Researchers unravel key mechanism of cellular damage in aging and disease
Researchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few. According to a study published today in the journal Cell, researchers have discovered a tool that can monitor related damage and determine the degree to which antioxidant drugs effectively combat disease.

Missing link found between circadian clock and metabolism
Two new research studies have discovered a long sought molecular link between our metabolism and components of the internal clock that drives circadian rhythms, keeping us to a roughly 24-hour schedule. The findings appear in the July 25 issue of the journal Cell, a publication of Cell Press.

Older people may need less sleep, study finds
Along with all the other changes that come with age, healthy older people also lose some capacity for sleep, according to a new report published online on July 24 in Current Biology, a Cell Press publication. When asked to stay in bed for 16 hours in the dark each day for several days, younger people get an average of 9 hours of shuteye compared to 7.5 for older people, the researchers report.

Consortium develops new method enabling routine targeted gene modification
A multi-institutional team led by Massachusetts General Hospital investigators has developed a powerful new tool for genomic research and medicine -- a robust method for generating synthetic enzymes that can target particular DNA sequences for inactivation or repair.

Scientists break record by finding northernmost hydrothermal vent field
Inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. The cluster of vents -- one towering nearly four stories -- are venting water as hot as 570 F. Dissolved sulfide minerals that solidify when vent water hits the icy cold of the deep sea have, over the years, accumulated around the vents in what is one of the most massive hydrothermal sulfide deposits ever found on the seafloor.

Energy drinks linked to risk-taking behaviors among college students
Over the last decade, energy drinks -- such as Red Bull, Monster and Rockstar -- have become nearly ubiquitous on college campuses. Although few researchers have examined energy drink consumption, a researcher at the University at Buffalo's Research Institute on Addictions has been investigating links between energy drinks and public health concerns like substance abuse and risky behaviors.

Joy Luck Club: The health benefits of daughters-in-law
In a new twist on the Confucian ideal of filial piety, a study finds that the assistance of daughters-in-law -- but not their own children -- helps mitigate depression among older people in China. Almost two-thirds of the older population in China lives in rural areas, making it the largest concentration of older adults in the world.

Researchers identify gene responsible for rare childhood disease
The chromosomal abnormality that causes a rare, but often fatal, disorder that affects infants has been identified by researchers at the University of California, San Diego School of Medicine, who happened to treat two young children with the disease in San Diego -- two of perhaps a dozen children in the entire country diagnosed with the disorder.

Genetic mutation identified for eye complaint
Researchers at the Peninsula Medical School, the Children's Hospital in Boston and King's College London have identified a gene that, when modified, causes the eye disease Duane syndrome. Importantly, by identifying this gene the team has discovered how the visual system develops which may lead to new ways to treat other vision disorders.

Electron microscopy enters the picometer scale
Juelich scientists have succeeded in precisely measuring atomic spacings down to a few picometers using new methods in ultrahigh-resolution electron microscopy. This makes it possible to find out decisive parameters determining the physical properties of materials directly on an atomic level in a microscope. Knut Urban from Forschungszentrum Juelich, a member of the Helmholtz Association, reports on this in the latest issue of the scientific high-impact journal Science.
