Frequent marijuana use can have negative effect on brains of teenagers

Frequent marijuana use can have a significant negative effect on the brains of teenagers and young adults, including cognitive decline, poor attention and memory, and decreased IQ, according to psychologists discussing public health implications of marijuana legalization at the American Psychological Association's 122nd Annual Convention.

Scientists find new clues to early detection, personalised treatment of ovarian cancer

Scientists at A*STAR's Institute of Medical Biology and the Bioinformatics Institute have found new clues to early detection and personalised treatment of ovarian cancer, currently one of the most difficult cancers to diagnose early due to the lack of symptoms that are unique to the illness.

Researchers awarded $3.3 million NIH grant to study role of genetics in protecting against frailty

Frailty is a common condition associated with old age, characterized by weight loss, weakness, decreased activity level and reduced mobility, which together increase the risk of injury and death. Yet, not all elderly people become frail; some remain vigorous and robust well into old-age.

Study: Younger and older adults show same responses for spatial attention tasks

At least one part of the human brain may be able to process information the same way in older age as it does in the prime of life, according to new research conducted at the University of Adelaide.

Scientists uncover new information on how stem cells in human bowel behave

For the first time, scientists have uncovered new information on how stem cells in the human bowel behave, revealing vital clues about the earliest stages in bowel cancer development and how we may begin to prevent it.

Research reveals that 59% of wines contain significant quantities of phthalate, dibutyl phthalate

Why alcohol may be even more damaging to your health then you first thought. We all know what risks our favourite wines and spirits pose to our health but now scientists reveal that the packaging of these drinks may be just as damaging. Is it time to leave that extra bottle of red on the supermarket shelf?

Scientists analyze genetic characteristics of cancers using multiple genomic technology platforms

New research partly led by UC San Francisco-affiliated scientists suggests that one in 10 cancer patients would be more accurately diagnosed if their tumors were defined by cellular and molecular criteria rather than by the tissues in which they originated, and that this information, in turn, could lead to more appropriate treatments.

Neurons derived from human iPSC and grafted into rats after spinal cord injury produce cells

Building upon previous research, scientists at the University of California, San Diego School of Medicine and Veteran's Affairs San Diego Healthcare System report that neurons derived from human induced pluripotent stem cells (iPSC) and grafted into rats after a spinal cord injury produced cells with tens of thousands of axons extending virtually the entire length of the animals' central nervous system.

Researchers find that animal's ability to endure internal parasite strongly influences reproductive success

In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success.

People who develop depression, MCI after age 65 are more vulnerable for accelerated brain aging

People who develop depression and mild cognitive impairment (MCI) after age 65 are more likely to have biological and brain imaging markers that reflect a greater vulnerability for accelerated brain aging, according to a study conducted by researchers at the University of Pittsburgh School of Medicine. The findings were published online in Molecular Psychiatry.

Infectious prion protein is marker for variant Creutzfeldt-Jakob disease

The misfolded and infectious prion protein that is a marker for variant Creutzfeldt-Jakob disease - linked to the consumption of infected cattle meat - has been detected in the urine of patients with the disease by researchers at The University of Texas Health Science Center at Houston (UTHealth) Medical School.
