Scientists May Be Able to Double Efficacy of Radiation Therapy

20.12.2011   |   Press monitoring

Scientists may have a way to double the efficacy and reduce the side effects of radiation therapy. Georgia Health Sciences University scientists have devised a way to reduce lung cancer cells' ability to repair the lethal double-strand DNA breaks caused by radiation therapy. "Radiation is a great therapy -- the problem is the side effects," said...

Hand hygiene -- clean hands, healthy body

19.12.2011   |   Press monitoring

Our hands are one of the chief ways we interact with our environment. Think about what you touch daily – doors, desks, food, other people, pets.

In Third-Degree Burn Treatment, Hydrogel Helps Grow New, Scar-Free Skin

16.12.2011   |   Press monitoring

Johns Hopkins researchers have developed a jelly-like material and wound treatment method that, in early experiments on skin damaged by severe burns, appeared to regenerate healthy, scar-free tissue. The researchers reported their promising results from mouse tissue tests. The new treatment has not yet been tested on human patients. But the...

Scientists identify human proteins that may fuel HIV/AIDS transmission

15.12.2011   |   Press monitoring

Scientists at the Gladstone Institutes have discovered new protein fragments in semen that enhance the ability of HIV, to infect new cells. Previously, scientists in Germany discovered that HIV transmission is linked to the presence of an amyloid fibril in semen. This fibril -- a small, positively charged structure derived from a larger protein...

Aging Human Bodies and Aging Human Oocytes Run On Different Clocks

12.12.2011   |   Press monitoring

Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span. The different genetic pathways help explain why a woman's fertility begins to decline after she is 35 years old, while her other cells do not show...

Rice as a source of arsenic exposure

9.12.2011   |   Press monitoring

The study just published by a Dartmouth team of scientists in the Proceedings of the National Academy of Sciences (PNAS) advances our understanding of the sources of human exposure to arsenic and focuses attention on the potential for consuming harmful levels of arsenic via rice. Arsenic occurs naturally in the environment and in elevated...

Why aren't we smarter already? Evolutionary limits on cognition

8.12.2011   |   Press monitoring

We put a lot of energy into improving our memory, intelligence, and attention. There are even drugs that make us sharper, such as Ritalin and caffeine. But maybe smarter isn’t really all that better. A new paper published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, warns that there are...

How fruit flies can teach us about curing chronic pain and halting mosquito-borne diseases

7.12.2011   |   Press monitoring

Studies of a protein that fruit flies use to sense heat and chemicals may someday provide solutions to human pain and the control of disease-spreading mosquitoes. In the current issue of Nature, biologist Paul Garrity of the National Center for Behavioral Genomics at Brandeis University and his team, spearheaded by KyeongJin Kang and Vince...

Breakthrough in the production of flood-tolerant crops

5.12.2011   |   Press monitoring

As countries such as Pakistan, Bangladesh, Vietnam and parts of the United States and United Kingdom have fallen victim to catastrophic flooding in recent years, tolerance of crops to partial or complete submergence is a key target for global food security. Starved of oxygen, crops cannot survive a flood for long periods of time, leading to...
