Common cold virus came from birds

Posted On: November 20, 2008 - 3:00pm

A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article published in the December issue of the Journal of General Virology. Scientists hope their findings will help us understand how potentially deadly viruses emerge in humans.

Bad cholesterol inhibits the breakdown of peripheral fat

Posted On: November 20, 2008 - 3:00pm

[PRESS RELEASE, 20 November 2008] The so called bad cholesterol (LDL) inhibits the breakdown of fat in cells of peripheral deposits, according to a study from the Swedish medical university Karolinska Institutet. The discovery reveals a novel function of LDL as a regulator of fat turnover besides its well-established detrimental effects in promoting atherosclerosis.

New method for tracing metal pollution back to its sources

Posted On: November 20, 2008 - 3:00pm

A new way of pinpointing where zinc pollution in the atmosphere comes from could improve pollution monitoring and regulation, says research out this week in the journal Analytical Chemistry.

Imperial College London researchers say their work is a major breakthrough as current methods for analysing zinc pollution only measure pollution in the atmosphere; they do not trace it back to its source.

People who have lost the ability to interpret emotion after a severe brain injury can regain this vital social skill by being re-educated to read body language, facial expressions and voice tone in others, according to a new study.

The research, published in the Journal of Head Trauma Rehabilitation, reveals that appropriate training can result in significant gains in "emotional perception", which is crucial for successful social communication.

Stopping germs from ganging up on humans

Posted On: November 20, 2008 - 3:00pm

Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson.

John W. Pepper proposes a new strategy in the arms race between humans and germs-- targeting the teamwork within gangs of germs.

Most drugs used to fight infections kill the vulnerable disease-causing organisms, or pathogens, but the resistant ones survive. The next generation will all carry the resistance to the drug.

New material could make gases more transportable

Posted On: November 20, 2008 - 2:40pm

Chemists at the University of Liverpool have developed a way of converting methane gas into a powder form in order to make it more transportable.

Scientists have developed a material made out of a mixture of silica and water which can soak up large quantities of methane molecules. The material looks and acts like a fine white powder which, if developed for industrial use, might be easily transported or used as a vehicle fuel.

Surgeons perform world's first pediatric robotic bladder reconstruction

Posted On: November 20, 2008 - 2:00pm

A 10-year-old Chicago girl born with an abnormally small bladder that made her incontinent has become the first patient to benefit from a new robotic-assisted bladder-reconstruction method developed by surgeons at the University of Chicago Medical Center.

The surgeons describe their innovative technique in the December 2008 issue of the journal Urology. They have now performed the operation, using the DaVinci robotic surgical system, six times, with good results and no significant complications.
