How your hands feel what you see

How your hands feel what you seeWashington, September 29 : Just to pick up a cup of morning coffee your brain makes a set of complex decisions.

It need to decide how to aim your hand, grasp the handle and raise the cup to your mouth, all without spilling the contents on your lap.

Now, a new Northwestern University study has revealed that, not only does your brain handle such complex decisions for you, it also hides information from you about how those decisions are made.

Women twice as likely to suffer UTI

Women twice as likely to suffer UTIWashington, Sep 27 - Women are more than twice as likely as men to suffer from urinary tract infections (UTI) caused by kidney stones, says a new finding.

Regenerating human limbs not easy: Study

Regenerating human limbs not easy: StudyWashington, Sep 26 - Regenerating a new limb or organ in humans may not be as easy as mad scientist Curt Connors makes it out to be in the Spider-man movies.

But by studying a real lizard-like amphibian, the salamander, which can grow missing limbs, Salk Institute of Biological Studies researchers discovered that it isn't enough to activate genes that kick start the regenerative process.


Synthetic drug shows promise in brain cancer

Synthetic drug shows promise in brain cancerWashington, Sep 26 - Researchers led by an Indian-origin investigator are testing the suitability of a synthetic cannabinoid drug - dexanabinol - for curing brain cancer. Preliminary tests show that it kills cultured cancer cells derived from many tumour types, a US report says.


Researchers get skin virus to knock out acne

Castration `secret of longer life for men

Castration `secret of longer life for menWashington, September 25 : Male sex hormones are responsible for shortening the lives of men, a new study has suggested.

The evidence comes after careful study of genealogy records of noble members of the Imperial court of the Korean Chosun dynasty (AD 1392-1910).

“This discovery adds an important clue for understanding why there is a difference in the expected life span between men and women,” Kyung-Jin Min of Inha University said.


Plastic additive BPA `harms human reproduction`

Plastic additive BPA `harms human reproduction`Washington, September 25 : In a new study, researchers have found new evidence that the plastic additive BPA can disrupt women’s reproductive systems, causing chromosome damage, miscarriages and birth defects.

Washington State University geneticist Patricia Hunt and colleagues at WSU and the University of California, Davis, report seeing reproductive abnormalities in rhesus monkeys with BPA levels similar to those of humans.


Alzheimer’s-like memory loss in animal models reversed

Alzheimer’s-like memory loss in animal models reversedWashington, September 25 : A team of neuroscientists and chemists have suggested that a class of currently used anti-cancer drugs as well as several previously untested synthetic compounds show effectiveness in reversing memory loss in two animal models of Alzheimer’s disease.


Depressed people can’t tell difference between feeling angry and guilty

Depressed people can’t tell difference between feeling angry and guiltyWashington, September 25 : Clinically depressed people may be less able to discriminate between different types of negative emotions compared to healthy individuals, suggests a new study.

These people often experience feelings of sadness, anger, fear, or frustration that interfere with everyday life.


Cancer research yields 'greening' of nylon

Cancer research yields 'greening' of nylonWashington, Sep 24 - Working on a cancer cure, researchers have discovered a molecule which would facilitate 'greening' of nylon production.

"In our lab, we study genetic changes that cause healthy tissues to go bad and grow into tumours. The goal of this research is to understand how the tumours develop in order to design better treatments," says Zachary J. Reitman, research associate at Duke University Medical Centre, who led the study.


Mole-rats hold key to pain relief

African naked mole rats `may hold clues to pain relief`

African naked mole rats `may hold clues to pain relief`Washington, September 22 : Researchers have described how naked mole-rats have evolved to thrive in an acidic environment that other mammals, including humans, would find intolerable.

In the tightly crowded burrows of the African naked mole-rats' world, carbon dioxide builds up to levels that would be toxic for other mammals, and the air becomes highly acidic.

Missing protein `kick-starts` male fertility

Missing protein `kick-starts` male fertilityWashington, September 22 : Adding a missing protein to infertile human sperm can "kick-start" its ability to fertilise an egg and dramatically increase the chances of a successful pregnancy, researchers say.

A team of researchers from Cardiff University first found that sperm transfers a vital protein, known as PLC-zeta (PLCz), to the egg upon fertilisation.


Dairy products `won’t make you skinny`

Dairy products `won’t make you skinny`Washington, September 22 : Adding a couple of servings of milk or yogurt to your daily diet won't help you drop any pants sizes, a new analysis of past studies has claimed.

Some research has suggested that dairy products may help people feel full for longer, or that the calcium in milk and yogurt can prevent the build-up of fat tissue but those remain unproven theories.
