DARIEN, IL - A new study found that after restricting sleep to 5 hours per night, caffeine use no longer improved alertness or performance after three nights.

Results show that relative to placebo, caffeine significantly improved Psychomotor Vigilance Task (PVT) performance during the first 2 days, but not the last 3 days of sleep restriction.

Lack of transportation is a hurdle for many families in Texas whose children could benefit from free summer meals from a federally funded program administered by Texas Department of Agriculture, according to a study by Texas Hunger Initiative at Baylor University.

A new experimental antibiotic developed by a team of scientists at Rutgers University successfully treats the deadly MRSA infection and restores the efficacy of a commonly prescribed antibiotic that has become ineffective against MRSA.

In research published in the July issue of Antimicrobial Agents and Chemotherapy, Rutgers scientists say that the combination of their newly developed antibiotic, TXA709, with cefdinir, an antibiotic that has been on the market for almost two decades, successfully treated the MRSA infection in animals.

Queen's University researcher Jacalyn Duffin and colleagues are recommending that Canada create a list of essential medicines to help protect against drug shortages.

Hundreds of countries have created an essential medicines list that typically includes between 200 and 500 medicines that the government commits to keep in stock. The list may include prescription drugs as well as over the counter drugs and natural products.

The next generation of nanosubmarines being developed at Rice University has been upgraded with tags that fluoresce longer, which enables the submersibles to be tracked for greater periods while being driven through a solution.

The single-molecule vehicles introduced by the Rice lab of chemist James Tour last year may someday be used to deliver drugs or other cargo. The new version built and tested with collaborators at Tel Aviv University in Israel is the subject of a recent paper in the American Chemical Society journal Organic Letters.

Examining databases of proteins' 3-D shapes, scientists at Washington University School of Medicine in St. Louis have identified more than 850 DNA mutations that appear to be linked to cancer. The information may expand the number of cancer patients who can benefit from existing drugs.

BAR HARBOR, MAINE - The MDI Biological Laboratory will offer three lectures for the public on the science of aging as part of its new signature course on aging. The presenters, all leaders in the field of aging research, will address tantalizing questions such as why do we age, what mechanisms regulate aging on a cellular level and can youthfulness be extended through genetic manipulation?

MANHATTAN, KANSAS -- Raelene Wouda's passion for improving cancer treatment starts with our four-legged friends.

Wouda, Kansas State University assistant professor of clinical sciences, is conducting clinical trials to treat cancers in dogs, cats and other companion animals.

When pet owners bring their dogs, cats, horses and other animals to the College of Veterinary Medicine's Veterinary Health Center for treatment, Wouda and the Oncology Service can offer groundbreaking new treatments often at a lower cost to pet owners.

Tracy C. Grikscheit, MD, pediatric surgeon and principal investigator at The Saban Research Institute of Children's Hospital Los Angeles, treats a large number of young patients who require surgery for various intestinal diseases. Since the intestinal microbiome is an important regulator of gut health and immune function, Grikscheit and her team investigated how surgical treatment of certain pediatric intestinal diseases have a long-term impact on intestinal flora.

DARIEN, IL - A new study found that alcohol-sleep relationship differed importantly by race and sex.

Exercise, particularly high-impact activity, builds stronger bones in children, even for those who carry genetic variants that predispose them to bone weakness, according to new research. The scientists say their findings underscore that genetics does not necessarily equate to destiny, and reinforce the importance of physical activity as a key factor to improve the bone health of children in the present and into later life.

COLLEGE STATION - Major rainfall across most of Texas triggering hordes of mosquitos coupled with seemingly constant mosquito-related Zika virus media reports from around the globe may have set the stage perfectly for what one researcher deems as a very significant discovery in man's war against earth's leading human disease carrier.

Researchers at The University of Texas Medical Branch at Galveston have found that cancer survivors who were diagnosed at adolescent and young adult ages are more likely to be current cigarette smokers than people who have not had cancer. The findings of this study are currently available in Cancer.

Smoking is the leading cause of cancer but the study found that cancer survivors were not staunch non-smokers.

Scientists used X-rays to discover what creates one butterfly effect: how the microscopic structures on the insect's wings reflect light to appear as brilliant colors to the eye.

The results, published today in Science Advances, could help researchers mimic the effect for reflective coatings, fiber optics or other applications.

A team led by researchers from UCSF and Yale has found that half of people newly infected with HIV experience neurologic issues. These neurologic findings are generally not severe and usually resolve after participants started anti-retroviral therapy.
