Youth high on cocaine run stroke risk within 24 hours

Youth high on cocaine run stroke risk within 24 hoursNew York, Feb 13 - Cocaine is not only addictive, it can also lead to disability or death from stroke within 24 hours of use, warn researchers.

Cocaine greatly increases ischemic stroke risk in young adults within a day of use.

Ischemic strokes occur when a blood vessel supplying blood to the brain becomes blocked, preventing a continuous supply of blood to the brain.

Device that listens to bacteria is here

Device that listens to bacteria is hereNew York, Feb 11 - Here comes a chip that can be used for a most unusual application - the study of signalling in bacterial colonies.

Researchers at Columbia University have developed a chip based on complementary metal-oxide-semiconductor (CMOS) technology that enables them to electrochemically image the signalling molecules from bacteria.

In effect, they have developed chips that 'listen' to bacteria.


Smoking may increase breast cancer risk

Smoking may increase breast cancer riskNew York, Feb 10 : Young women who smoke have a significantly higher risk of developing most common type of breast cancer, a study shows.

The majority of recent studies evaluating the relationship between smoking and breast cancer risk among young women have found that smoking is linked with an increased risk.

The present study, published in the online journal Cancer, evaluates the risks according to different subtypes of breast cancer.


Decoded: How brain controls hunger

Decoded: How brain controls hungerNew York, Feb 9 - Although hunger is essential for survival, abnormal hunger can lead to obesity and eating disorders that are now reaching near-epidemic proportions around the world. The solution lies somewhere deep inside your brain.

To unlock the mystery behind hunger pangs, researchers are creating a wiring diagram of the complex brain circuits that regulate the intense urge to munch in office or rush for refrigerator in night.


Believe it! Tumour removed from under the nail

TumourNew York, Feb 8 - Ever heard of a tumour under a fingernail? Even the man who has been diagnosed with one didn't believe it.

The man, in his 40s, noticed a dark line under his nail after an injury, which he assumed was a splinter.

But the mark remained in the same place for three years without changing, according to media reports.


Decoding why motor functions decline with age

New York, Feb 8 - Research has found a clue why muscles weaken with age.

According to scientists from University of Texas' health science center at San Antonio, 'set points' in the nervous system are not inalterably determined during development but instead can be reset with age.

They observed a change in 'set point' that resulted in significantly diminished motor function in aging fruit flies.


Even shivering can help you burn fat!

Even shivering can help you burn fat!New York, Feb 5 : Can shivering due to cold weather lead to weight loss? Not exactly. But shivering does trigger a response in muscles of people out in the cold similar to that of exercise, showed research.

The muscles of shivering people triggers the release of a hormone called irisin that activates brown fat - a type of fat found in humans that burns energy to generate heat.
