Space-age ceramics get their toughest test

Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next generation gas turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge – until now. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first testing facility that enables CT-scanning of ceramic composites under controlled loads at ultrahigh temperatures and in real-time.

Metformin improves blood glucose levels and BMI in very obese children

Chevy Chase, MD ––Metformin therapy has a beneficial treatment effect over placebo in improving body mass index (BMI) and fasting glucose levels in obese children, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). The study showed reduction in BMI was sustained for six months.

Mother's vitamin D level linked to birth weight

Chevy Chase, MD –– Mothers' vitamin D levels at a gestation of 26 weeks or less were positively related to birth weight and head circumference, and, in the first trimester were negatively associated with risk of a baby being born small for gestational age, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Prevention through design: A new approach to reduce construction risks

"Some of the most pressing occupational health hazard risks in construction" are associated with masonry operations, asphalt roofing, and welding, wrote Deborah Young-Corbett in an article recently accepted by the Journal of Civil Engineering and Management.

Just 28 percent of young people in Spain read either online or conventional newspapers each day

A study at the Jaume I University in Castellón has verified the decrease in press consumption among young people between the ages of 16 and 30 years, which now stands at 28.8%. What is more, three out of every four individuals within this age bracket use social networking sites more than the television to get up to date.

News consumption habits among young people have changed radically in recent years. Since the beginning of the 21st century, various studies have indicated a decrease in readership of printed newspapers along with a constant fall in young readers.

Tracking gene flow in marine plant evolution

A new method that could give a deeper insight into evolutional biology by tracing directionality in gene migration has just appeared in EPJ Data Science. Paolo Masucci from the Centre for Advanced Spatial Analysis, at University College of London, UK, and colleagues identified the segregation of genes that a marine plant underwent during its evolution. They found that the exchange of genes, or gene flow, between populations of a marine plant went westward from the Mediterranean to the Atlantic.

Study of text messaging service shows participants prepared for motherhood

Following last week's mHealth Summit, the largest event of its kind where leaders focus on how wireless technology can improve health outcomes, text4baby announced results from the first randomized evaluation of its service. The largest mobile health initiative in the U.S., text4baby was found to be an effective service for pregnant women.

Stem cell research provides hope for infertile cancer survivors

Radiation and chemotherapy can pack a powerful punch against all kinds of cancers. Those who survive, however, are often left with bad news: Their treatments have rendered them infertile.

A UTSA professor has now demonstrated that it is possible to remove testicular stem cells from a monkey prior to chemotherapy, freeze them and later, after cancer treatments, transplant these cells where they can restart sperm production and restore fertility.

Benefit of PET or PET/CT in recurrent bowel cancer is not proven

For patients in whom a recurrence of bowel cancer is suspected, the study data currently available allow no robust conclusions as to the advantages and disadvantages of using positron emission tomography (PET), alone or in combination with computed tomography (CT). This is because no studies have directly compared the benefits of these imaging techniques in recurrent colorectal carcinoma (bowel cancer) with conventional diagnostic techniques. Although PET or PET/CT show a higher diagnostic accuracy, i.e.

In vitro study finds digested formula, but not breast milk, is toxic to cells

Free fatty acids created during the digestion of infant formula cause cellular death that may contribute to necrotizing enterocolitis, a severe intestinal condition that is often fatal and occurs most commonly in premature infants, according to a study by University of California, San Diego bioengineers. Their report, which was based on in vitro tests comparing the digestion of fresh human breast milk and nine different infant formulas, was published online in the journal Pediatric Research.

To make old skin cells act young again, boost their surroundings, U-M scientists show

ANN ARBOR, Mich. — As we get older, the trillions of cells in our body do too. And like us, they become less resilient and able to weather the stress of everyday life. Our skin especially tells the tale of what's happening throughout our bodies.

But recently, scientists have learned that aging cells bear only part of the blame for this downward spiral. And a new study shows that it might be possible to slow the decline of aging tissue – and even make it act younger -- by focusing on the stuff that surrounds those cells.

Leading experts urge Europe to implement personalized medicine in healthcare

Strasbourg, France, 10 December, 2012: Dedicated funding and support is required to ensure personalised medicine can be implemented across Europe's healthcare systems, according to a new report issued by the European Science Foundation's (ESF) membership organisation for all medical research councils in Europe, the European Medical Research Councils (EMRC).

Survey shows breakthrough medical research relies heavily on NIH funding

(ATLANTA, December 10, 2012) – A survey highlighting the correlation between today's cutting edge medical research and the National Institutes of Health (NIH) funding was released today at the 54th Annual Meeting of the American Society of Hematology (ASH), the preeminent medical meeting for physicians and scientists in hematology that draws more than 20,000 attendees from around the world. The survey, representing responses from 1,040 abstract presenters from the U.S. and abroad, demonstrates how critical NIH funding has been to the success of science and medicine.

Researchers demonstrate that a saliva analysis can reveal decision-making skills

A study conducted by researchers at the University of Granada Group of Neuropsychology and Clinical Psychoneuroimmunology has demonstrated that cortisol levels in saliva are associated with a person's ability to make good decisions in stressful situations.

To perform this study, the researchers exposed the participants (all women) to a stressful situation by using sophisticated virtual reality technology. The study revealed that people who are not skilled in decision-making have lower baseline cortisol levels in saliva as compared to skilled people.

Experiment finds ulcer bug's Achilles' heel

Experiments at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have revealed a potential new way to attack common stomach bacteria that cause ulcers and significantly increase the odds of developing stomach cancer.
