Scientists have identified a protein that can be modified to improve the effectiveness of one of the most common drugs used to treat pancreatic cancer. ANI

How mushrooms evolved alongside humans
A researcher at Oregon State University and her team has published one of the most detailed genetic analyses ever done on morels or mushrooms, to help identify their ancestry, show how they evolved and what conservation policies may be needed to manage and protect this valuable resource. ANI

Higher brain rhythm linked to increased sleep fragility
A new study has found that a brain rhythm signifies an individual's vulnerability to disturbance by the outside world while asleep. ANI

Brain cells prone to Alzheimer's attack grown in lab
Scientists have grown brain cells that are prone to an attack from Alzheimer's for the first time in a breakthrough that could help reverse memory loss. ANI

Soot on Tibetan snow 'causes more rainfall over India and China'
A new study has suggested that in some cases, soot - the fine, black carbon silt that is released from stoves, cars and manufacturing plants - can pack more of a climatic punch than greenhouse gases. ANI

New HIV/AIDS study could turn treatment 'on its head'
A new study of anti-HIV/AIDS medicines in the developing world is on the verge of turning "the whole treatment world on its head," says expert. ANI

Chinese medicinal plant extract may help develop anticancer drugs
A natural product isolated from a traditional Chinese medicinal plant commonly known as thunder god vine and used for rheumatoid arthritis could be a starting point for developing new anticancer drugs, suggest scientists. ANI

Study finds enzyme that gives rats better long-term memories
A new study has found that increased levels of a natural brain enzyme gives rats better recall of old remembrances. ANI

'David and Goliath' viruses key to origin of jumping genes
Researchers have discovered a pair of 'David and Goliath' viruses that could provide clues to the evolutionary origin of some jumping genes found in other organisms. ANI

Study finds enzyme that is 'the killer you can't live without'
Scientists have discovered an enzyme that has a double role - on one end it can push cells to commit suicide but on the other, it may actually short circuit a second form of cell death. ANI

Here's how the Arctic will look by the end of this century
A new study has estimated climate change's impact on Arctic regions by 2099. ANI

Some Antarctic ice is building up from bottom
New findings by scientists working in the remotest part of Antarctica could reshape our understanding of how the ice sheet expands and moves, and how it might react to climate change. ANI

Increasing CO2 'causing plants to release less water to atmosphere'
Scientists have reported that as carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the atmosphere. ANI

'Eye tracking' laptop, 'telepresence robot' debut at Germany Science fair
There might come a day soon when you won't even have to lift your hand to click an icon on the screen - instead all you have to do is move your eyes and your laptop will do as you wish - open files, play music or view pictures. ANI

Genetic pathways involved in breast cancer identified
Scientists have uncovered a genetic pathway that affects the development of breast cancer. ANI

Men living in low-income neighborhoods 'drink more than women'
A new study has shown that men living in low-income neighbourhoods consume more than three times as many alcoholic drinks each week compared to women in these neighbourhoods. ANI

Genetic treatment to thwart HIV shows promise
A ground-breaking treatment to prevent HIV by genetically altering blood cells so the virus cannot invade them has shown promise in initial tests. ANI

Liver, not brain, may be source of Alzheimer's plaques
A new study has suggested that the plaques associated with Alzheimer's disease start in the liver and not in the brain-completely altering scientists' ideas about the disease. ANI

Discrimination increases health problems in obese people
Scientists have suggested that the discrimination that obese people feel, whether it is poor service at a restaurant or being treated differently in the workplace, may have a direct impact on their physical health. ANI

MRSA danger in gyms may be exaggerated
A new study has found that community gym surfaces do not appear to be reservoirs for MRSA transmission. ANI

Experts have found that star-shaped brain cells called astrocytes, which were earlier considered little more than structures to fill the gaps between all-important neurons, have a function that's a lot more important. ANI

Our ancestors preferred to live on shaky ground
A new study has suggested that our earliest ancestors preferred to settle in locations that have something in common with cities like San Francisco, Naples and Istanbul-they are often on active tectonic faults in areas that have an earthquake risk or volcanoes, or both. ANI
