Cancer treatment potential discovered in gene repair mechanism

Posted: 30 Dec 2014 11:52 AM PST

A two-pronged therapeutic approach has been discovered that shows great potential for weakening and then defeating cancer cells. The research team's complex mix of genetic and biochemical experiments unearthed a way to increase the presence of a tumor-suppressing protein which, in turn, gives it the strength to direct cancer cells toward a path that leads to their destruction.

Detecting extraterrestrial life through motion

Posted: 29 Dec 2014 01:48 PM PST

An extremely sensitive device that can detect life forms by sensing the slightest motion has been developed by scientists. The chemistry-free system can be used to rapidly test antibiotics or even to search for life on other planets, the researchers say.

Report on remission in patients with MS three years after stem cell transplant

Posted: 29 Dec 2014 01:48 PM PST

Three years after a small number of patients with multiple sclerosis (MS) were treated with high-dose immunosuppressive therapy and then transplanted with their own hematopoietic stem cells, most of the patients sustained remission of active relapsing-remitting MS and had improvements in neurological function, according to a study.

Year of birth significantly changes impact of obesity-associated gene variant

Posted: 29 Dec 2014 01:48 PM PST

Investigators working to unravel the impact of genetics versus environment on traits such as obesity may also need to consider a new factor: when individuals were born. A new study finds that the impact of a variant in the FTO gene that previous research has linked to obesity risk largely depends on birth year, with no correlation between gene variant and obesity in study participants born in earlier years and a far stronger correlation than previously reported for those born in later years.

Sugar molecule links red meat consumption and elevated cancer risk in mice

Posted: 29 Dec 2014 12:22 PM PST

While people who eat a lot of red meat are known to be at higher risk for certain cancers, other carnivores are not, prompting researchers to investigate the possible tumor-forming role of a sugar called Neu5Gc, which is naturally found in most mammals but not in humans.

Prospects of developing computing and communication technologies based on quantum properties of light and matter may have taken a major step forward thanks to new research.

Binge drinking disrupts immune system in young adults, study finds

Posted: 29 Dec 2014 06:26 AM PST

Binge drinking in young, healthy adults significantly disrupts the immune system, according to a study. Drinkers generally understand how binge drinking alters behavior, researchers note, however, there is less awareness of alcohol's harmful effects in other areas, such as the immune system.

Christmas colors disguise gliding lizards in the rainforest

By mimicking the red and green colors of falling leaves, Bornean lizards avoid falling prey to birds whilst gliding, new research has found.

Dominant people can be surprisingly social

Posted: 20 Nov 2014 09:30 AM PST

In contrast to the lay stereotype, dominant people prove to be avid social learners, just like dominant individuals in the animal kingdom. Neuroscientists show this with a complex decision-making task. They offer a more subtle perspective on the lay view wherein dominant individuals ignore others' views and advice.

Spinach extract decreases cravings, aids weight loss

A spinach extract containing green leaf membranes called thylakoids decreases hedonic hunger with up to 95 percent -- and increases weight loss with 43 percent, research concludes.

Link between vitamin D, dementia risk confirmed

Posted: 06 Aug 2014 01:16 PM PDT

Vitamin D deficiency is associated with a substantially increased risk of dementia and Alzheimer's disease in older people, according to the most robust study of its kind ever conducted. An international team found that study participants who were severely vitamin D deficient were more than twice as likely to develop dementia and Alzheimer's disease.
