This finding has significant implications for developing new ways to detect, diagnose and treat cancer and diseases of the immune system.

But macrophages do much more than that -- not only do they act as antimicrobial warriors, they also play critical roles in immune regulation and wound-healing.

They can respond to a variety of cellular signals and change their physiology in response to local cues.

That's according to a new study that examined the role of laughter in jury deliberations during a capital murder case.

Researchers were given access to the full transcript of jury deliberations in the 2004 Ohio trial of Mark Ducic, a white male charged with two murders and 30 additional counts, largely related to drug violations.

Thirty-one of 75 patients hospitalised for opioid detoxification told researchers that they first got hooked on drugs legitimately prescribed for pain.

Women who ate an average of one to two servings of high cocoa chocolate per week had a 32 per cent lower risk of developing heart failure.

The flexible plastic sheets have inspired a new inexpensive way to create, test and mass-produce large-area patterns on the nanoscale.

The team from the Universities of Manchester and York say that the home dates to at least 8,500 BC -- when Britain was still attached to the continental European landmass.

These positions include manager of research and development, director of finance, mechanical engineer and construction supervisor.

We also imitate other people's speech patterns, including inflections, talking speed and speaking style -- even foreign accents of people we talk to.

A new study shows that unintentional speech imitation can even make us sound like people whose voices we never hear.

Scientists have previously found genetic material from retroviruses in vertebrate genomes.

Now a team of researchers have now discovered that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses -- two deadly virus families.

Researchers have devised a new method for simpler, faster 'data mining' -- a way to simply extract and analyse massive amounts of this data.

Buckyballs were previously thought to float through space, but they had evaded detection until now.

Current flu vaccines do not generate such broadly neutralising antibodies -- which is why they must be re-formulated each year to match the predominant virus strains in circulation.

Now another small fish is living in the oxygen-depleted dead zone and feasting upon the ecologically dead-end jellyfish.

The synthetic cannabinoid called MDA19 seems to avoid side effects by targeting one specific subtype of the cannabinoid receptor.
