Increasing total sleep time may help improve athletic performance

Young basketball players spend hours dribbling up and down the court aspiring to NBA stardom. Now, new Stanford University School of Medicine research suggests another tactic to achieving their hoop dreams: sleep.

Scientists use statistical approach to assess order of genetic abnormalities in cancers

Zeroing in on the early cell mutations that enable a cancer to grow is one of the best ways to find a personalized therapy to stop it. Scientists were able to use a statistical approach for the first time to map out the order in which these abnormalities form to analyze the pattern of DNA changes in advanced skin and ovarian tumors.

Infected astrocytes can cause neuroAIDS

A longstanding medical mystery - why so many people with HIV experience memory loss and other cognitive problems despite potent antiretroviral therapy - may have been solved by researchers at Albert Einstein College of Medicine of Yeshiva University.

DHS S&T develops personal dosimeter to measure radiation exposure

No matter how many plastic cards currently crowd your wallet, one day you may wish to make room for one more. The Department of Homeland Security's Science and Technology Directorate has developed a miniaturized version of a dosimeter, a portable device used for measuring exposure to ionizing radiation, which can provide life-saving early detection in the unlikely event of a nuclear accident or dirty bomb.

New stem cell bioprinting for uniform, controlled size embryoid body formation

Ever since an ordinary office inkjet printer had its ink cartridges swapped out for a cargo of cells about 10 years ago and sprayed out cell-packed droplets to create living tissue, scientists and engineers have never looked at office equipment in quite the same way. They dream of using a specialized bio-inkjet printer to grow new body parts for organ transplants or tissues for making regenerative medicine repairs to ailing bodies.

Aquatain surface layer helps control malaria mosquitoes in rice-agro ecosystems

A thin, liquid layer applied on the surface of inundated rice paddies effectively kills malaria mosquito larvae without having an impact on other aquatic life. Rice yield remains the same and water was saved because of the anti-evaporative properties of the layer.

MGH researchers discover new plant compounds that block blood vessel growth

Massachusetts General Hospital (MGH) researchers have discovered the first of an entirely new class of antiangiogenesis drugs - agents that interfere with the development of blood vessels.

Changes in individual sport performance linked to physiological laws

Geoffroy Berthelot and Stephane Len, both researchers at the IRMES, have published their findings in AGE, the official journal of the American Aging Association, describing the evolution of performances in elite athletes and chess grandmasters.

Antimicrobial copper surfaces reduce risk of acquiring hospital infection

Professor Bill Keevil, Head of the Microbiology Group and Director of the Environmental Healthcare Unit at the University of Southampton, has presented research into the mechanism by which copper exerts its antimicrobial effect on antibiotic-resistant organisms at the World Health Organization's first International Conference on Prevention and Infection Control.

GWAS identifies 15 gene variants responsible for diversity of white blood cell counts

A trio of large-scale genome-wide association studies, or GWAS, have identified more than 15 gene variants responsible for the diversity of white blood cell counts among whites, African-Americans, and Japanese.

Unhealthy food adverts on TV induce children to to eat high-fat and high-sugar foods

Researchers at the University of Liverpool have found that children who watch adverts for unhealthy food on television are more likely to want to eat high-fat and high-sugar foods.

Scientists discover enzyme that can regulate breast cancer development

Researchers at Cold Spring Harbor Laboratory (CSHL) have identified an enzyme that appears to be a significant regulator of breast cancer development. Called PTPN23, the enzyme is a member of a family called protein tyrosine phosphatases, or PTPs, that plays a fundamental role in switching cell signaling on and off.

Research sheds light on well-documented 'other-race effect'

Northwestern University researchers have provided new biological evidence suggesting that the brain works differently when memorizing the face of a person from one's own race than when memorizing a face from another race.

New analytical approach can organize large amounts of varied cancer genetic data

The technology that allows scientists to profile the entire genome of individual tumors offers new hope for discovering ways to select the best treatment for each patient's particular type of cancer. However, these profiles produce huge amounts of data, and the volume alone creates unique analytical problems.

Sleep extension improves athletic performance

A study in the July 1 issue of the journal SLEEP shows that sleep extension is beneficial to athletic performance, reaction time, vigor, fatigue and mood in collegiate basketball players. The study is the first to document sleep extension and the athletic performance of actively competing athletes.

Study provides novel information about clinical potential of anti-cancer antibiotics

Most of us have had a doctor prescribe an antibiotic for a stubborn bacterial infection, or for a cut that gets infected. However, prescribing an antibiotic to fight cancer? In fact, anti-cancer antibiotics have been used since the 1950s to successfully treat several forms of cancer, but often the side effects limit the duration they can be given to a patient.

New technique can remove oil spill from soil

It is well known just how damaging oil can be to nature. It is also well known just how difficult it can be to clean up after a spill or contamination. Removing an oil spill or contamination from soil is hard and requires very different techniques to removing oil from water.
