London, Apr 2: Scientists are on their way to provide double bonanza to women looking for healthy skin – a moisturiser containing Viagra that could resolve cellulite issues.

The drug sildenafil has had mixed success as a drug for women, but according to Croatian researchers incorporating the stuff into a moisturiser could open up a whole new market, reports New Scientist.

London, Apr 2 : Scientists have discovered a method that can manage the amount of fat that cells store for use as a back-up energy source, and can eventually lead to therapies for liver disease and diabetes.

Researchers at Albert Einstein College of Medicine of Yeshiva University have also found that the process, if disrupted, can enable cellular fat to accumulate, a key factor in age-related metabolic diseases such as obesity and type 2 diabetes.

They reckon that the discovery of this previously unknown fat-fighting pathway may lead to novel drugs for the treatment of metabolic syndrome - characterised by obesity, blood lipid disorders, and insulin resistance - and for a common liver disease known as "fatty liver" or steatohepatitis.

Washington, April 2 : Cannabinoids such as the main active component of marijuana (THC) have anticancer effects on human brain cancer cells, a new study has found.

In the study, Guillermo Velasco and colleagues at Complutense University, Spain, found that THC induced the death of various human brain cancer cell lines and primary cultured human brain cancer cells by a process known as autophagy.

Consistent with the in vitro data, administration of THC to mice with human tumours decreased tumour growth and induced the tumour cells to undergo autophagy.

Washington, Apr 2: Researchers from UC Davis Cancer Centre have identified a protein that may allow breast cancer to spread and make it resistant to drugs.

The research team led by Kermit Carraway have discovered a protein called Muc4, which belongs to a group of proteins called mucins, commonly found in fluids such as tears and mucus.

"Breast cancer deaths are caused by metastasis, not by the primary tumour," said Carraway.

Washington, Apr 2: Proposing a new theory of autism, scientists have revealed that the brains of autistic people are structurally normal but dysregulated, which implies that the disorder might be reversible.

The theory put forward by scientists at Albert Einstein College of Medicine of Yeshiva University is centred on the principle that autism is a developmental disorder caused by impaired regulation of the locus coeruleus-a bundle of neurons in the brain stem that processes sensory signals from all areas of the body.

Washington, Apr 2 : Think you're doing your teeth a favor by sipping white wine instead of tea or coffee? Well, its time you rework the tooth-whitening mantra, for a new study has found that the transparent beverage increases the risk of dark dental stains.

In the study, NYU dental researchers compared two sets of six cow teeth, whose surface closely resembles that of human teeth, and used a spectrophotometer, an instrument that measures color intensities, to evaluate staining levels.
