A Weighty Matter:
Is Earth Getting Lighter or Heavier?
As time goes on, does the Earth lose mass or gain it?
A physicist has calculated that the planet sucks in tonnes of space dust every year due to gravity, but it's still losing mass.
From BBC News:
For instance, the Earth's core is like a giant nuclear reactor that is gradually losing energy over time, and that loss in energy translates into a loss of mass.

Breaking Down Brain Waves To Hear
US scientists have demonstrated that the brain decodes sounds into patterns of electrical currents and based on the correlation between sound and electric activity in brain's temporal lobe they were able to predict the words the person heard.
However any practical use in case of patients who cannot talk is a long way of because this research is based on what a person actually hears, rather than thinks of...
From The Guardian:
Experiments on 15 patients in the US showed that a computer could decipher their brain activity and play back words they heard, though at times the words were difficult to recognise.
"This is exciting in terms of the basic science of how the brain decodes what we hear," said Robert Knight, a senior member of the team and director of the Helen Wills Neuroscience Institute at the University of California, Berkeley.

Hot Topic:
Is Global Warming Just Hot Air?
Global warming is one of the most controversial issues of our time.
Now 16 scientists have publishing an op-ed in the Wall Street Journal that casts doubt on the orthodox view of climate change.
From The Wall Street Journal:
In September, Nobel Prize-winning physicist Ivar Giaever, a supporter of President Obama in the last election, publicly resigned from the American Physical Society (APS) with a letter that begins: "I did not renew [my membership] because I cannot live with the [APS policy] statement: 'The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth's physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.' In the APS it is OK to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible?"

Happy Anniversary:
Mars Rover's Eight Year Mission
The Mars rover Opportunity has just marked eight years on the red planet.
While its companion rover Spirit bit the dust long ago, Opportunity has managed to keep on trucking as it searches for signs of life.
From Time:
It was on January 25, 2004 that the rover Opportunity — swaddled in its cocoon of shock-absorbing air bags — bounced down on Mars for a mission designed to last a minimum of three months and a maximum of just a year or two. Eight years later, Opportunity is slower, creakier and much, much dirtier, and yet it's still at work, hunkering down on the crater rim as it prepares to ride out another bitter Martian winter. When the relative warmth and sunlight of spring return, the golf-cart-sized rover will resume its wanderings, adding to the mass of data it's already collected about Mars's wet, balmy, and perhaps biologically active past.

Russia Eyes Moon Base With Nasa
In spite of the failure of the recent Phobos-Grunt mission, Russia's space programme is still forging ahead with ambitious ideas.
One possible way forward might be a joint base on the Moon in cooperation with Nasa.
From The Register:
"We don’t want the man to just step on the Moon,” agency chief Vladimir Popovkin said in an interview with Vesti FM radio station. “Today, we know enough about it. We know that there is water in its polar areas," he added. "We are now discussing how to begin [the Moon’s] exploration with NASA and the European Space Agency."

No Guts, No Glory:
Genetically Engineered Gut Bacteria Turn Seaweed Into Biofuel
Biofuels have been controversial as they have caused the prices of crops such as corn to rise.
But researchers may have found a way to turn abundant seaweed into ethanol using genetically engineered E.coli bacteria -- which could eventually be used to manufacture other substances such as plastics.
From Scientific American:
The microbe could turn out to be useful for making molecules other than ethanol, such as isobutanol or even the precursors of plastics, Yoshikuni says. "Consider the microbe as the chassis with engineered functional modules," or pathways to produce a specific molecule, Yoshikuni says. "If we integrate other pathways instead of the ethanol pathway, this microbe can be a platform for converting sugar into a variety of molecules."

Hotshots:
Coronal Mass Ejection From Sun Heads For Earth
A coronal mass ejection (CME) from the Sun is heading for Earth but don't panic just yet.
Whilst the CME was originally predicted to head straight for us, it now looks like we're in for a near miss.
From The Washington Post:
“At first glance, it was, ‘Oh my God, it’s at the center of the [sun’s] disk, it ought to go right to the Earth,’ ” Kunches said. But upon further review and “head-scratching” Thursday, NOAA’s space weather team calculated that most of the plasma blob should pass harmlessly over the top of our planet.

Methods to defeat counterfeiters such as holograms often don't take long to be circumvented.
So the US Department of Defense are turning to DNA as a way of embedded invisible 'barcodes' that are impractical to replicate.
From Wired:
“DNA is beyond what the bad guys can copy,” Hayward says. “You can counterfeit your way through visual inspection, through X-Rays. DNA is easily the strongest platform for authentication in the world.”

Here's Ears:
Scientists Create Tiniest Microphone Ever
Scientists have developed the smallest microphone ever created, using gold nanoparticles and lasers.
The tiny microphone could record the sound of activity inside the smallest cells.
From ScienceNOW:
Feldmann's team recorded and analyzed the movements of this particle in response to acoustic vibrations caused by the laser-induced heating of other gold nanoparticles in the water nearby. As well as having unprecedented sensitivity, their nano-ear could also calculate the direction the sound had come from. They suggest three-dimensional arrays of nano-ears working together could be used to listen in on cells or microorganisms such as bacteria and viruses, all of which emit very faint acoustic vibrations as they move and respire. "There are definitely medical opportunities which we can tackle together with the right people," Feldmann says, "but we just have to see how it works first."

iPhone 1983:
Archives Reveal Apple's Early Telephony Experiments
A peek into Stanford University's archives has revealed that Apple experimented with prototype phones as early as 1983.
The company gave its archives to Stanford in 1997 but most of the material has remained private until now.
From Mashable:
The phone was designed for Apple by Hartmut Esslinger, an influential designer who helped make the Apple IIc computer (Apple’s first “portable” computer) and later founded Frogdesign. The 1983 iPhone certainly fits in with Esslinger’s other designs for Apple. It also foreshadows the touchscreens of both the iPhone and iPad.

Junk Food Causes Brain Shrinkage
A diet rich in trans fats from junk food could result in brain shrinkage and eventual dementia, according to new research.
By avoiding these harmful fats and consuming more beneficial omega fatty acids, this shrinkage could be prevented.
From BBC News:
Study author Gene Bowman of Oregon Health and Science University said: "These results need to be confirmed, but obviously it is very exciting to think that people could potentially stop their brains from shrinking and keep them sharp by adjusting their diet."

Japan Pioneers Biometrics of the Bottom
Biometrics for security such as iris recognition is becoming more commonplace.
The newest variation has been created by Japanese researchers -- a car seat that identifies you by the impression left by your bottom.
From PhysOrg:
They say that traditional biometric techniques such as iris scanners and fingerprint readers cause stress to people undergoing identity checks, while the simple act of getting seated carries less psychological baggage. Their other point is that other technologies such as fingerprint scanning can be compromised when sensor surfaces are unclean, or when there is poor lighting as in iris scanning, contaminating results.

Adults Only:
Vending Machine That Detects Your Age
When food manufacturer Kraft wanted to distribute samples of a new pudding, they didn't want to attract negative publicity by giving them to children.
To that end, they have introduced a new type of vending machine that uses facial recognition to detect if you are an adult or not.
From Gizmag:
Kraft's goal of course is to ensure its samples are reaching their target demographic, but also hopes the odd machines will draw in consumers as well. According to Charlotte Maumus, PR rep for Kraft:
"Temptations is the first Jell-O dessert made just for adults, so it makes sense that this breakthrough technology dispenses free samples to adults only. Showcasing the future of how consumers could interact with products and sample more easily, if the machine detects a child, it will shut down, asking the child to step away from the machine. But if it detects an adult, then a tasty sample is dispensed."

LHC Discovers New Particle, But It's Not The Higgs Boson
Scientists analysing data from the Large Hadron Collider believe that they have discovered a new kind of particle, but it's not a Higgs boson.
The Chi-b(3P) is a boson like the Higgs that combines a beauty quark and its antiquark so that they bind together.
From The University of Birmingham:
Professor Roger Jones, Head of the Lancaster ATLAS group said: ‘While people are rightly interested in the Higgs boson, which we believe gives particles their mass and may have started to reveal itself, a lot of the mass of everyday objects comes from the strong interaction we are investigating using the Chi-b.’

Recently developed at Harvard University this cheap and biodegradable material promises wide applications either in consumer market or medical professions.
Called "Shrilk" as it is made of of protein in silk and chitin (commonly extracted from shrimp shells) it has properties similar to an aluminium alloy but only half the weight and it degrades quickly. One of the many practical uses could be a replacement for ubiquitous plastic bags.

Kepler-22b potentially has liquid water and consequently could support life.
From BBC News:
Kepler 22-b lies 15% closer to its sun than the Earth is to our Sun, and its year takes about 290 days. However, the planet's host star puts out about 25% less light, keeping the planet at its balmy temperature that would support the existence of liquid water.

The problem has grown so large that restauranteurs are planning to use DNA fingerprinting to ensure diners get what they pay for.
From AP
Mislabeling is widespread in the seafood industry and usually involves cheaper types of fish being sold as more expensive varieties. A pair of New York high school students using DNA barcoding of food stocked in their own kitchens found in a 2009 study that caviar labeled as sturgeon was actually Mississippi paddlefish.

Help Wanted:
US Military Need Help Securing Networks
Darpa, the US military research agency responsible for the creation of the Internet, has admitted that it needs more help to secure networks.
Public networks like the Internet are far too porous and vulnerable to attack, so Darpa is soliciting ideas for solutions to the problem.
From Wired:
Because it’s the blue-sky research agency that helped create the internet, Darpa framed the problem as a deep, existential one, not a pedestrian question of insecure code. “It is the makings of novels and poetry from Dickens to Gibran that the best and the worst occupy the same time, that wisdom and foolishness appear in the same age, light and darkness in the same season,” mused Regina Dugan, Darpa’s director. She’s talking about the internet. “These are the timeless words of our existence. We know it is true of everything.”

Lifelike:
Biology Inspires Technology
One of the biggest trends in contemporary science is biomimicry, where new developments are based on techniques already seen in nature.
Now researchers have developed a reusable adhesive tape with remarkable properties based on the wall climbing abilities of gecko lizards.
From Gizmag:
The secret to the wall climbing ability of many insects and geckos lies in the thousands of tiny hairs called setae that cover their feet and legs. The sheer abundance of these hairs, coupled with flattened tips that can splay out to maximize contact on even rough surface areas, make it sufficient for the Van der Waals forces, which operate at a molecular level and are relatively weak compared to normal chemical bonds, to provide the requisite adhesive strength that allows them to scurry along walls and ceilings.

A Fishy Tale:
Fish Evolve to Survive Toxic Conditions
Researchers have discovered certain fish living in New York's Hudson river have mutated to survive in toxic conditions.
Polychlorinated biphenyls (PCBs) are amongst the most toxic substances known to humanity, yet the fish in question have adapted.
From The Economist:
The species of interest to Dr Wirgin is the Atlantic tomcod of the Hudson river in upstate New York. Part of the Hudson was polluted with PCBs by two General Electric plants. Dr Hahn is looking at a different animal, the killifish (pictured), in New Bedford harbour, Massachusetts, which was polluted by other producers. Both Hudson tomcod and New Bedford killifish are able to tolerate levels of PCB far higher than those that would kill such fish in cleaner waters. The question is, why?

Genes From Food Found in Bloodstream
Scientists have discovered that genetic material from the food we consume can enter our bloodstream and affect the expression of genes.
Micro RNA molecules found in food can bind with messenger RNA in our cells and alter our metabolism.
From Discover:
It’s only logical that what we eat has an effect on the expression of our genes, in the general sense that nutrients from food are involved in cellular processes that control and are controlled by gene expression. But this is an unusually direct route, and surprising from an organism that’s so different from mammals.

3D printers are used for a variety of applications from rapid prototyping to creating artificial blood vessels for transplant.
But criminals are also using the technology to fashion flawless card skimmers used to steal money from ATM users.
From Krebs on Security:
“Just looking at the idea of 3D printing a potential skimming device, a criminal could invest in buying a desktop 3D printer,” De Schouwer wrote in an email to KrebsOnSecurity. “Not a kit printer in the line of a Makerbot or a RepMan but a desktop printer of a high end manufacturer of 3D printers like Objet, 3D Systems or Stratasys (HP). You could get one of those between $10,000 – $20,000 and they will print a high quality skimming device that, including some post finishing, will look like the real thing.”

Lithium batteries used in laptops and handhelds have experienced safety problems in the past that led to them exploding.
But a new technique replaces the liquid electrolyte used in the batteries with a gel that makes them much safer.
From BBC News:
"Safety is of paramount importance in lithium batteries. Conventional lithium batteries use electrolytes based on organic liquids; this is what you see burning in pictures of lithium batteries that catch fire. Replacing liquid electrolytes by a polymer or gel electrolyte should improve safety and lead to an all-solid-state cell," said Professor Peter Bruce from the University of St Andrews, who was not involved in the study.

Bright Idea:
Nuclear Fusion With Lasers
The UK has joined an initiative to create power from nuclear fusion using lasers.
The approach taken by the National Ignition Facility (Nif) is yielding more promising results than previous efforts using Tokamaks.
From BBC News:
Dr Moses said that a single shot from the Nif's laser - the largest in the world - released a million billion neutrons and produced for a tiny fraction of a second more power than the world was consuming.

Larry vs Larry:
Judge Asks Oracle & Google to Attend Mediation
Oracle is currently suing Google over the use of Java in the Android operating system for mobiles.
Now the judge in the case is recommending that the respective heads of both companies attend mediation to resolve the case.
From ITworld:
Now it's up to the magistrate judge, Paul Singh Grewal, to decide which executives should appear. In his Thursday order, Alsup referred the mediation to Grewal and recommended that he order Ellison and Page, as well as the executives the companies already suggested, to attend. But he said the final determination is up to Grewal.

Small Wonder:
World's Smallest Electric Motor
Scientists have created an electric motor from a single molecule.
The motor is one nanometre long and could eventually be used in applications such as cooling microprocessors.
From New Scientist:
If accepted by Guinness, the motor will be a record smasher. The current world-record holder for the smallest electric motor is a giant by comparison, composed of two 200-nanometre-long carbon nanotubes. Current running through these nanotubes pushes drops of molten metal from the outside of one tube to the other.

Orbital Junkyard:
Space Debris Reaches 'Tipping Point'
Orbital debris has reached a 'tipping point' that could prove disastrous, according to a new report.
The amount of space junk currently in orbit could lead to a self-sustaining chain reaction and drastically worsen the problem.
From Reuters:
Some computer models show the amount of orbital debris "has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures," the research council said in a statement released Thursday as part its 182-page report.

WikiLeaks Leaks:
Cache of Unredacted Cables Unearthed
German newspaper Der Freitag claims to have unearthed a cache of unredacted diplomatic cables from WikiLeaks.
How exactly the cache came to light is unclear, but it may indicate a leak within the ranks of WikiLeaks itself.
From PC Magazine:
WikiLeaks usually redacts documents before it releases them, meaning it removes the names of informants or vulnerable sources. Many of the of the documents uncovered by Der Freitag had been published by WikiLeaks in the past, but they're not official WikiLeaks files and they have not been edited for sensitive information in the usual way. Its pages contained "named or otherwise identifiable 'informers' and 'suspected intelligence agents' from Israel, Jordan, Iran, and Afghanistan," Der Freitag said.

Abandonment Issues:
Space Station Could Be Mothballed
The recent failure of a Russian supply rocket to the International Space Station could have disastrous consequences for the crew currently in orbit.
With the end of the Space Shuttle program and the grounding of the Soyuz-U rocket until investigations are completed, the ISS crew may have to vacate the station by the end of the year.
From Discovery:
Should no resolution be found, 11 years of continuous manned presence on the ISS will come to an end, experiments will be shelved and there will likely be lengthy delays to SpaceX's plans of carrying out an unmanned docking of their Dragon vehicle by the end of the year.

Genes For Green:
Cannabis Genome Sequenced
A Dutch genomics company has released the first complete genetic sequence for Cannabis sativa.
This could lead to the development of pharmaceutical drugs based on the plant's therapeutic qualities.
From Nature:
Thus far the company is only posting the raw sequence reads – meaning that the over 131 billion bases of shotgun sequence have not yet undergone the important and arduous process of being assembled into contiguous chunks. For now, the sequence is fragmented into hundreds of thousands of snippets. But Medicinal Genomics founder Kevin McKernan says he estimates the size of the C. sativa genome to be about 400 million bases – roughly three times the genome of that other weed, the model plant Arabidopsis thaliana.

13-Year-Old Scientist Makes Solar Power Breakthrough
A 13-year-old scientist has invented a new kind of solar array based on the mathematics behind the growth of trees.
Using the Fibonacci sequence, Aidan Dwyer designed a tree-like solar array that is more efficient than current designs.
From The American Museum of Natural History:
My conclusions suggest that the Fibonacci pattern in trees makes an evolutionary difference. This is probably why the Fibonacci pattern is found in deciduous trees living in higher latitudes. The Fibonacci pattern gives plants like the oak tree a competitive edge while collecting sunlight when the Sun moves through the sky.

It's A Small World:
Earth Is Not Expanding
Since Darwin's time, scientists have wondered whether the Earth is expanding.
A recent study has concluded that Earth's radius expands by 0.1 miliimetres a year -- an amount so minuscule that it's not statistically significant.
From ScienceDaily:
The team applied a new data calculation technique to estimate the rate of change in the solid Earth's average radius over time, taking into account the effects of other geophysical processes. The previously discussed geodetic techniques (satellite laser ranging, very-long baseline interferometry and GPS) were used to obtain data on Earth surface movements from a global network of carefully selected sites. These data were then combined with measurements of Earth's gravity from NASA's Gravity Recovery and Climate Experiment (GRACE) spacecraft and models of ocean bottom pressure, which help scientists interpret gravity change data over the ocean.

Amazon CEO Proposes Airbags For Mobiles
Jeff Bezos, CEO of Amazon, has filed a patent for a system that protects mobile devices from damage.
When a device is dropped, airbags could be deployed inside the casing to prevent damage.
From GeekWire:
One idea is to embed one or more small airbags inside the phone, according to the filing. If the device is at risk of damage from a fall, the airbags would instantly inflate via an embedded cartridge of compressed air or carbon dioxide. The monitoring system could either detect which side of the phone will hit the ground, and deploy the airbag there, or pop airbags out of multiple sides of the device.

Antisec Hacks Police Academy
Antisec, a hacking group affiliated with Anonymous, have released over 7,000 records taken from a police training academy's website.
The intrusion is supposedly in retaliation for the recent arrest of 14 individuals relating to last December's attack on PayPal's servers.
From The Register:
Many of the passwords employed by the officers were ordinary dictionary words, or were identical to their names or badge numbers, showing that law enforcement agents often make the same careless mistakes others do in setting up security pass codes. Assuming these people used the same password for other accounts, as is common, their email accounts would also be compromised.

The Whole Truth:
Is Space-Time Holographic?
Could everything we see around us actually be a hologram?
Some scientists are wondering if our 3D universe is generated from a 2D interference pattern, much like the way a hologram is created.
From New Scientist:
It sounds crazy, but we have already seen a sign that it may be true. Theoretical physicists have long suspected that space-time is pixelated, or grainy. Since a 2D surface cannot store sufficient information to render a 3D object perfectly, these pixels would be bigger in a hologram. "Being in the [holographic] universe is like being in a 3D movie," says Craig Hogan of Fermilab in Batavia, Illinois. "On a large scale, it looks smooth and three-dimensional, but if you get close to the screen, you can tell that it is flat and pixelated.

Professor Bradley Joliff of Washington University in St. Louis and his colleague found an upsurge of magma composed of molten silicon and radioactive thorium among other elements.
From ScienceDaily:
"We don't have a way to get an absolute date on the Compton-Belkovich volcanic feature because we don't have rocks in hand," Jolliff says, "but since there are relatively few craters, the surface actually looks pretty fresh. And we see small-scale features that haven't been completely beaten up and obliterated by the impact process.

Texas Rejects Creationist Textbooks
The Texas Board of Education has approved textbooks based on scientific theories of evolution over those proposing creationism.
Two years ago, the board changed the curriculum to allow teaching of 'intelligent design', but the creationist textbooks submitted for approval were riddled with errors.
"This is a huge victory for Texas students and teachers," said Josh Rosenau, NCSE programs and policy director, who testified at the hearings this week. In his testimony, Rosenau urged the board to approve the supplements--recommended by a review panel largely composed of scientists and science educators--without amendments, and to reject International Database's creationist submission. The board did just that, and asked for only minimal changes to the approved supplements.

Memory Drain:
Is Google Affecting Our Ability to Remember?
Technology is meant to improve our lives yet it could have unintended consequences.
Researchers are investigating whether our increasing reliance on tools such as search engines is compromising our ability to remember information.
From Wired:
These results suggest that processes of human memory are adapting to the advent of new computing and communication technology. Just as we learn through transactive memory who knows what in our families and offices, we are learning what the computer “knows” and when we should attend to where we have stored information in our computer-based memories. We are becoming symbiotic with our computer tools, growing into interconnected systems that remember less by knowing information than by knowing where the information can be found.

Computer Learns Language by Playing Games
Researchers have developed an artificial intelligence (AI) that can read a game manual and go on to learn language through gameplay.
Giving the AI a manual increased its rate of victory from 46 per cent to 79 per cent.
From MIT:
“Games are used as a test bed for artificial-intelligence techniques simply because of their complexity,” says Branavan, who was first author on both ACL papers. “Every action that you take in the game doesn’t have a predetermined outcome, because the game or the opponent can randomly react to what you do. So you need a technique that can handle very complex scenarios that react in potentially random ways.”

Francis Thackeray previously found traces of cannabis in pipe fragments found in the Bard's garden.
From io9:
Thackeray says that if there is any hair or nail fragments left on the corpse, his team would be able to perform chemical analyses that could detect even highly minute quantities of marijuana. Thackeray says he plans to use laser surface scanning, which could image the skeletons of Shakespeare, his wife Anne Hathaway, and his daughter Susanna without directly disturbing them. There's also the possibility of taking DNA samples from the bard's teeth, which could also reveal what Shakespeare's diet was like.

From New Scientist:
Having successfully hijacked a hand, the researchers tried to teach it how to play the koto, a traditional Japanese stringed instrument. Koto players wear different picks on three fingers, but pluck the strings with all five fingertips, so each finger produces a distinctive sound. A koto score tells players which fingers should be moved and when, and from this Tamaki and her team were able to generate instructions telling their device how and when to stimulate the wearer's muscles.

Revolutionary Camera Announced
A new start-up has revealed a innovative approach to photography.
Lytro's camera captures the entire 'light field' rather than a single shot, meaning you can tweak focusing post-shot and even create 3D images.
From TechCrunch:
Of course there are big risks with any business this jaw-droppingly innovative. Will they be able to get the price point low enough that people will buy the camera? Right now, the closest Ng will commit on price is somewhere between north of $1 and less than $10,000. That’s a pretty broad ballpark. We won’t be able to see the devices until the also vague “sometime this year.” An equally important question is whether the user experience be as simple as the company claims.

Solar activity may decline in the next few years according to recent research.
This may lead to a drop in temperatures here on Earth.
From Network World:
"This is highly unusual and unexpected," stated Dr. Frank Hill, associate director of the NSO's Solar Synoptic Network, in a statement. "But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation. We expected to see the start of the zonal flow for Cycle 25 by now, but we see no sign of it. This indicates that the start of Cycle 25 may be delayed to 2021 or 2022, or may not happen at all."

Scientists now believe that the Moon has far more water than previously suspected.
Analysis of volcanic glass beads found on the Moon in 1972 has revealed a water level comparable to that found in Earth's upper mantle magma.
From Discover:
In this new research, the scientists found (in 2008, actually, but their results are now confirmed) that the beads have a water content of about 750 parts per million, roughly equivalent to what you’d find in magma in the Earth’s upper mantle. That’s very surprising; many of the rocks on the Moon’s surface are very dry*, which for years has led scientists to assume the Moon itself was very dry.

Did the Universe Start Out as a 1D Line?
Whilst the Big Bang Theory is favoured by most physicists as an explanation for the universe's origins, there are alternative theories being advanced.
One states that our 3D universe originated as a 1D line that grew to become more intricate.
From MMN:
"In 1-D, there's a new sense of unification," Stojkovic told Life's Little Mysteries, a sister site to SPACE.com. "Right now, you see the diverse world because you're in 3-D. When you go down to 1-D, things become much simpler. Properties that distinguish all the different particles don't exist anymore, so they all become alike. There is no rotation. All you have is forward and backward, and energy moving in either direction."

Quantum Teleportation Breakthrough
Researchers have successfully teleported light, a breakthrough in the emerging fields of quantum communications and computing.
While quantum teleportation has been theorised about for a decade, it has been difficult to put into practice.
From PhysOrg:
"Just about any quantum technology relies on quantum teleportation. The value of this discovery is that it allows us, for the first time, to quickly and reliably move quantum information around. This information can be carried by light, and it’s a powerful way to represent and process information. Previous attempts to transmit were either very slow or the information might be changed. This process means we will be able to move blocks of quantum information3 around within a computer or across a network, just as we do now with existing computer technologies.

Cannabis is considered by many to be a wonder drug, but its euphoric qualities have held back widespread use as a mediciine.
Now a breakthrough has identified a way to use cannabis compounds for pain relief without the high.
From io9:
Physiologist Li Zhang and colleagues discovered that THC targets several parts of the nervous system, some of which are called inhibitory glycine receptors (GlyRs). These receptors, according to Zhang, help regulate "neuromotor activity, pain sensation, muscle relaxation and anxiety." He and his fellow researchers speculate that a synthetic THC could be made that targets just GlyRs - hence, a form of cannabis that works as a painkiller but doesn't get you high.

Breast of Breed:
GM Cows Produce 'Human-Like' Milk
Scientists have genetically modified cows to produce milk similar to that from humans.
But GM campaigners are likely to be critical of the new development.
From The Sunday Telegraph:
The scientists also revealed at an exhibition at the China Agricultural University that they have boosted milk fat content by around 20 per cent and have also changed the levels of milk solids, making it closer to the composition of human milk as well as having the same immune-boosting properties.

Making Ripples:
Comets Perturb Jupiter and Saturn's Rings
Ripples in the rings of Saturn and Jupiter have been traced back to collisions with cometary fragments that took place more than a decade ago.
In Jupiter's case, the culprit was the transit of comet Shoemaker-Levy 9 through our solar system in 1994.
From Science Daily:
"What's cool is we're finding evidence that a planet's rings can be affected by specific, traceable events that happened in the last 30 years, rather than a hundred million years ago," said Matthew Hedman, a Cassini imaging team associate, lead author of one of the papers, and a research associate at Cornell University, Ithaca, N.Y. "The solar system is a much more dynamic place than we gave it credit for."

Hide & Seek:
Covert Robot Knows How to Hide
Lockheed Martn have developed a surveillance robot that can infiltrate a building whilst avoiding humans.
The robot uses lasers to create a 3D map of the building and has sensors to detect approaching footsteps.
From New Scientist:
"Lockheed Martin's approach does include a sort of basic theory of mind, in the sense that the robot makes assumptions about how to act covertly in the presence of humans," says Alan Wagner of the Georgia Institute of Technology in Atlanta, who works on artificial intelligence and robot deception.

Seeing the Light:
Minature Lasers Could Revolutionise Computing
As ever increasing amounts of data are transmitted over the internet, conventional technologies will begin to struggle with heavy loads.
But a newly developed minature laser could revolutionise the way we communicate.
From Science Daily:
"The new laser diodes represent a sharp departure from past commercial devices in how they are made," Deppe said from his lab inside the College of Optics and Photonics. "The new devices show almost no change in operation under stress conditions that cause commercial devices to rapidly fail."

Steel This Bike:
Bicycle Made From Nylon as Strong as Steel
Aerospace company EADS have developed a bicycle made from nylon that is as strong as steel.
The bike's components are 'grown' from a fine nylon powde using a technique similar to 3D printing.
From Gizmag:
Complete sections are "grown" from the chosen structural material, with the wheels, bearings and axle incorporated within the process and built at the same time. EADS says that the nylon components produced by the ALM process are strong enough to replace steel or aluminum. Unsurprisingly perhaps for the company, the eight-bladed wheels are based on the scimitar propeller design of the Airbus A400M, and the bike's name follows a similar line to that of Airbus, the first EADS company to use the technology.

Heavy Drinking:
Happy Hours Lead to Violence
Researchers at Cardiff University have established a link between 'happy hour' drinks promotions and alcohol-fuelled violence.
The study highlights the need for bar staff to be more vigilant about serving drinks to already intoxicated customers.
From ScienceDaily:
Dr Simon Moore, of Cardiff University's award-winning Violence and Society Research Group, who led the study, said: "Our findings clearly show that alcohol misuse and violence are not simply caused by drinkers' weaknesses. The way premises are run also contributes, suggesting the industry still has more to do in playing its part."

A Quantum of Solace:
Quantum Computers Come One Step Closer
Quantum computers have come one step closer with the development of a quantum 'antenna'.
The antenna allows communication between memory cells on a quantum computing chip.
From Science Daily:
"The new technology offers the possibility to distribute entanglement. At the same time, we are able to target each memory cell individually," explains Rainer Blatt. The new quantum computer could be based on a chip with many micro traps, where ions communicate with each other through electromagnetic coupling. This new approach represents an important step towards practical quantum technologies for information processing.

Rocket Science:
ISS Could Go Interplanetary
Nasa researchers have come up with an innovative and inexpensive solution for interplanetary travel.
They want to attach rockets to the International Space Station and turn it into a spaceship.
From Discovery:
The designers optimistically believe that such a planet-roaming "space station with rockets" could be ready by 2020 at a cost of under $4 billion. If this number is realistic, the vehicle would be cheaper than the projected costs for the "Apollo-on steroids" Orion capsule.

Hot Stuff:
Iceland Looks to Magma for Energy
Iceland has been looking into hot springs as a way of generating energy.
When a borehole struck magma in 2009, it was seen as a setback initially.
But now researchers think that magma could be a huge source of energy for the country.
From PhysOrg:
"Because we drilled into magma, this borehole could now be a really high-quality geothermal well," said Peter Schiffmann, professor of geology at UC Davis and a member of the research team along with fellow UC Davis geology professor Robert Zierenberg and UC Davis graduate student Naomi Marks. The project was led by Wilfred Elders, a geology professor at UC Riverside.

Source Code:
CEO Open Sources His Genome
Open source software has made today's net possible -- many of the servers you use everyday rely on code released by the author for public use.
Manu Sporny, founder and CEO of Digital Bazaar, has taken the idea to the next level.
He has released around one million of his genetic markers into the public domain and ceded all rights to the data.
From Geek:
The body has around 10 million single-nucleotide polymorphisms (SNPs) – the genetic markers Manu shared – of which 23andme analyze 1 million by placing your saliva sample on a genotyping beadchip. Of those million, only 14,515 are known about in science, and only 160 are used by 23andme for analysis.

Skynet Edges Closer:
Robots Share Abilities on Web
Researchers are working on a 'web for robots' that will allow the devices to share information over a network.
This could mean that robots could extend their programming to take on tasks they were not originally developed to do.
From Engadget:
It's not quite war-ready, but a new Skynet-like initiative called RoboEarth could have you reaching for your guide to automaton Armageddon sooner than you think. The network, which is dubbed the "World Wide Web for robots," was designed by a team of European scientists and engineers to allow robots to learn from the experience of their peers, thus enabling them to take on tasks that they weren't necessarily programmed to perform.

Electricity in Mind:
Electric Brain Fields Unlock Secrets of Cognition
It has been assumed that brain function depends on neurons connected directly by synapses.
Now scientists believe that electric fields generated in the brain could cause unconnected neurons to fire.
From Caltech:
The brain—awake and sleeping—is awash in electrical activity, and not just from the individual pings of single neurons communicating with each other. In fact, the brain is enveloped in countless overlapping electric fields, generated by the neural circuits of scores of communicating neurons. The fields were once thought to be an "epiphenomenon" similar to the sound the heart makes—which is useful to the cardiologist diagnosing a faulty heart beat, but doesn't serve any purpose to the body, says Christof Koch, the Lois and Victor Troendle Professor of Cognitive and Behavioral Biology and professor of computation and neural systems at the California Institute of Technology (Caltech).
New work by Koch and neuroscientist Costas Anastassiou, a postdoctoral scholar in biology, and his colleagues, however, suggests that the fields do much more—and that they may, in fact, represent an additional form of neural communication.

Fingered:
Getting Fingerprints From Clothing
It has been virtually impossible to get fingerprints from clothing until now.
Researchers have found a way to reveal prints using gold vapour.
From Gizmag:
The researchers used a method known as vacuum metal deposition that's already been used to recover print detail on smooth surfaces like carrier bags, plastics and glass since the 1970s, but has not previously been applied to fingerprint detection on fabrics.
The fabric is placed in a vacuum chamber. Gold is heated and evaporated and spread in a fine layer over the fabric. Heated zinc is then applied, which attaches to the gold layer where the fabric has no fingerprints, leaving the original fabric to show through where contact has been made.

Bigger Than It Looks:
Universe Could Be 250 Times Larger Than Previously Thought
The size of the Universe is a topic that has exercised cosmologist's brains for decades.
A new statistical analysis indicates that the Universe may be 250 times larger than previously thought.
From Technology Review:
They say that the curvature of the Universe is tightly constrained around 0. In other words, the most likely model is that the Universe is flat. A flat Universe would also be infinite and their calculations are consistent with this too. These show that the Universe is at least 250 times bigger than the Hubble volume. (The Hubble volume is similar to the size of the observable universe.)

A Load of Gas?:
Synthetic Petroleum From Hydrogen
Scientists have developed a synthetic form of petroleum derived from hydrogen.
The hydrogen-based fuel may be suitable for use in petrol engines without modification.
From Gizmag:
“We have developed new micro-beads that can be used in an existing gasoline or petrol vehicle to replace oil-based fuels,” said Voller. “Early indications are that the micro-beads can be used in existing vehicles without engine modification.”
“The materials are hydrogen-based, and so when used produce no carbon emissions at the point of use, in a similar way to electric vehicles”, said Voller.

Old Amoeba Had a Farm:
The Amoeba That Farms Bacteria
A species of amoeba that farms its own food source has been discovered.
Dictyostelium discoideum spores contain the bacteria that the slime mould relies on.
From BBC News:
Once Ms Brock spotted the amoebas' fruiting bodies carrying bacteria, she measured how many of the spores were responsible, finding that about a third of them traveled with their bacterial seeds.
The behaviour seems to be genetically built-in; clones of the "farmer" amoebas in turn developed into farmers, while clones of the "non-farmers" did not.
"To think of a single-celled amoeba performing something that you could consider farming, I think, is surprising," Ms Brock said.

The Worm That Turned:
Controlling Worms With Laser Light
Scientists have discovered a way to control the behaviour of worms using laser light.
Individual neurons can be turned on and off using an emerging technique known as Optogenetics.
From Science News:
“This tool allows us to go in and poke and prod at those neurons in an animal as it’s moving, and see exactly what each neuron does,” says study coauthor Andrew Leifer of Harvard University.
The system is based on the emerging field of optogenetics, in which light is used to turn cells on or off. Leifer and his colleagues genetically engineered light-responsive molecules into particular groups of cells in the worm.
Then, a computer program that the team developed figures out where in the microscope’s field of view a target cell is. Once the cell is pinpointed, the program directs lasers so that a tiny beam of light hits the cell.

Woolly Thinking:
Scientist Plans to Resurrect Mammoths
Advances in genetics have opened up the possibility that long extinct species could be resurrected.
So a Japanese scientist is on the hunt for a sample of soft tissue from a Wooly Mammoth that could lead to the return of the species.
From the Daily Telegraph:
Previous efforts in the 1990s to recover nuclei in cells from the skin and muscle tissue from mammoths found in the Siberian permafrost failed because they had been too badly damaged by the extreme cold.
But a technique pioneered in 2008 by Dr. Teruhiko Wakayama, of the Riken Centre for Developmental Biology, was successful in cloning a mouse from the cells of another mouse that had been frozen for 16 years.

That Which is Not Dead Can Eternal Lie:
34,000 Year Old Bacteria Discovered
A scientist has discovered 34,000 year old bacteria still living inside salt crystals.
As their DNA would have been damaged over the years, the discovery could shed light on how DNA repair takes place.
From Yahoo News:
"It was actually a very big surprise to me," said Brian Schubert, who discovered ancient bacteria living within tiny, fluid-filled chambers inside the salt crystals.
Salt crystals grow very quickly, imprisoning whatever happens to be floating - or living - nearby inside tiny bubbles just a few microns across, akin to naturally made, miniature snow-globes.
"It's permanently sealed inside the salt, like little time capsules," said Tim Lowenstein, a professor in the geology department at Binghamton University and Schubert's advisor at the time.

There's a Fly in My Soup:
Insects as a Green Source of Protein
Environmental problems could pose a threat to the world's food supply. Our current system of intensive farming may not have much of a future.
But scientists have come up with an alternative to the resource-intensive raising of livestock: insects.
From Science Daily:
The study indicates that proteins originating from insects in principle form an environmentally-friendly alternative to proteins from meat originating from conventional livestock. Further research is required to ascertain whether the production of a kilogram of insect protein is also more environmentally friendly than conventional animal protein when the entire production chain is taken into account.

Regeneration:
Turning Old Black & White TV Programmes Into Colour
The BBC is notorious for having wiped hundreds of TV programmes in the 1970s to save on the costs of video tape.
Over a hundred episodes of Doctor Who were lost. But a number of episodes were transferred to black & white 16mm film for export to countries such as Australia that were still broadcasting in monochrome.
Now restoration experts are using a clever application of science to restore these black and white prints to full colour.
From Wired UK:
Their method is a refined version of that trialled on the 2009 Planet of the Daleks rerelease; it is now being deployed on a seven-part 1970 Jon Pertwee adventure, The Ambassadors of Death. "It seemed almost impossible," says Steve Roberts, 35, the team's supervisor and a BBC senior engineer. "But when they made the black-and-white recordings, they didn't filter off the colour carrier [encoded as a 'chroma dot' pattern in each frame], which for the last few decades has been nothing more than an annoyance." Team member Richard Russell used the signal to reverse-engineer raw colour pictures that could be retouched frame by frame. "It's very, very labour intensive -- several hundred man hours' work every episode," says Roberts. Luckily, a new "quadrant editor" is helping them to produce better source material upfront, so they hope to deliver the Ambassadors episodes to the BBC within weeks.

Project Aims to Simulate Entirety of Earth
A group of scientists hope to create a simulator that can replicate everything happening on Earth.
The Living Earth Simulator aims to improve scientific understanding of what is taking place on the planet.
From BBC News:
Thanks to projects such as the Large Hadron Collider, the particle accelerator built by Cern, scientists know more about the early universe than they do about our own planet, claims Dr Helbing.
What is needed is a knowledge accelerator, to collide different branches of knowledge, he says.
"Revealing the hidden laws and processes underlying societies constitutes the most pressing scientific grand challenge of our century."

The Rules of Attraction:
Why Does Earth's Magnetic North Pole Drift?
As well as the geographic north pole, there is a magnetic north pole nearby. But the location of the magnetic pole moves from year to year for reasons unknown.
Finding an explanation for the phenomenon could unlock some of the secrets held beneath Earth's crust.
From Scientific American:
The north magnetic pole (NMP), also known as the dip pole, is the point on Earth where the planet's magnetic field points straight down into the ground. Scottish explorer James Clark Ross first located the NMP in 1831 on the Boothia Peninsula in what is now northern Canada, and with the planting of a flag claimed it for Great Britain.
But the NMP drifts from year to year as geophysical processes within Earth change. For more than 150 years after Ross's measurement its movement was gradual, generally less than 15 kilometers per year. But then, in the 1990s, it picked up speed in a big way, bolting north–northwest into the Arctic Ocean at more than 55 kilometers per year. If it keeps going it could pass the geographic north pole in a decade or so and carry on toward Siberia. But why?

Wildlife:
Drug-Using Animals
It may come as a surprise to learn that animals in the wild make use of psychoactive substances just like humans.
Many recreational drugs may in fact have been discovered by observing the behaviour of animals.
From PJ Online:
On the prairies of the south-west US, horses and other grazing mammals can become addicted to hallucinogen-containing plants known generically as locoweed. These plants, mainly species of Astragalus and Oxytropis, are normally avoided, but animals that try them can come back time and again for a repeat fix. Symptoms include altered gait, aimless wandering, impaired vision, erratic behaviour and listlessness.
In South America’s rain forests, jaguars have been filmed behaving in a kittenish manner after gnawing the bitter roots and bark of yage (Banisteriopsis caapi), a hallucinogenic vine that is also used by native tribes in ritualistic ceremonies. Some anthropologists believe that man first learnt to use the drug after watching jaguars

Light Touch:
A Hands-free Way to Review Radiological Images
Microsoft's Kinect motion-controller has been adapted to provide doctors with a hands-free way to review radiological images.
This allows them to maintain sterility by eliminating the need to touch any physical controls that could harbour pathogens.
From Gizmag:
With software based on ofxKinect, libfreenect and open frameworks, the prototype uses a mix of voice control via a wireless headset and gesture control via the Kinect’s 3D video camera to control OsiriX, an image processing application specially designed for navigation and visualization of medical images. The user can switch modes using voice commands and then navigate the images – zooming in or out and moving the view through a 3D image – using one or two-handed gestures.
While the focus of the Virtopsy project is to make use of new technologies to replace standard autopsy with minimally invasive procedures, such a touch-free interface also has obvious benefits for surgeons needing to navigate medical images in a surgery environment. Gesture and voice controls would allow them to maintain sterility by doing away with the need to directly touch any keyboards, buttons, joysticks or touchscreens.

The End of the World is Not Nigh:
Large Hadron Collider Doesn't Create Black Holes
The Large Hadron Collider (LHC) was mired in controversy before its launch when some thought that it could generate microscopic black holes. There were even allegations that the Earth could get sucked into one of these black holes.
But it turns out that Armageddon will probably not be caused by the LHC. Experiments that theoretically could have generated microscopic black holes have failed to yield any evidence of their existence.
From PhysOrg:
Microscopic black holes are predicted to exist in some theoretical models that attempt to unify General Relativity and Quantum Mechanics by postulating the existence of extra "curled-up" dimensions, in addition to the three familiar spatial dimensions.
At the high energies of the Large Hadron Collider, such theories predict that particles may collide "closely enough" to be sensitive to these postulated extra dimensions. In such a case, the colliding particles could interact gravitationally with strengths similar to those of the other three fundamental forces – the Electromagnetic, Weak and Strong interactions. The two colliding particles might then form a microscopic black hole.
