Exploring the function of sleep
Is sleep essential? Ask that question to a sleep-deprived new parent or a student who has just pulled an "all-nighter," and the answer will be a grouchy, "Of course!"

Study reveals how blood flow force prevents clogged arteries
Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology.

New evidence debunks 'stupid' Neanderthal myth
Research by UK and American scientists has struck another blow to the theory that Neanderthals (Homo neanderthalensis) became extinct because they were less intelligent than our ancestors (Homo sapiens).

Alcohol consumption can cause too much cell death, fetal abnormalities
The initial signs of fetal alcohol syndrome are slight but classic: facial malformations such as a flat and high upper lip, small eye openings and a short nose.

Why wind turbines can mean death for bats
Power-generating wind turbines have long been recognized as a potentially life-threatening hazard for birds. But at most wind facilities, bats actually die in much greater numbers.

How does bluetongue virus survive through the winter?
In 2006, Bluetongue virus - which infects livestock - reached Northern Europe for the first time. Some people thought that the outbreak would be limited to that particular year, as winter was expected to kill off the midges that host and spread the disease, bringing the threat of infection to an end. In actuality, the disease escalated in the following year, spreading to the UK. So, how did the virus survive the winter?

Study: DNA barcoding in danger of 'ringing up' wrong species
DNA barcoding is a movement to catalog all life on earth by a simple standardized genetic tag, similar to stores labeling products with unique barcodes. The effort promises foolproof food inspection, improved border security, and better defenses against disease-causing insects, among many other applications.

75 percent of athletes' parents let their child skip exams for a game
Three quarters of parents of young athletes let their child forgo an exam for an important game, a new study conducted at the University of Haifa has found. In comparison, only 47% of parents of young musicians will agree to their child choosing a performance over an exam.

How to get a college roommate you can live with
Anxious college freshmen can relax. No matter who will be sharing their dorm room, they have the power to make the relationship better, University of Michigan research suggests.

How 'secondary' sex characters can drive the origin of species
The ostentatious, sometimes bizarre qualities that improve a creature's chances of finding a mate may also drive the reproductive separation of populations and the evolution of new species, say two Indiana University Bloomington biologists.

Anti-psychotic drug use in the elderly increases despite drug safety warnings
Three regulatory warnings of serious adverse events slowed the growth of use of atypical antipsychotic drugs among elderly patients with dementia, but they did not reduce the overall prescription rate of these drugs.

Century-old rule of chemistry overturned -- major implications for drug delivery
A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls.

New hope for stroke patients
If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain.

Hospice and palliative medicine specialty strives to prepare physicians for aging baby boomers
The American Academy of Hospice and Palliative Medicine announces two important medical education courses in hospice and palliative medicine and a significantly revised book series in keeping with the Academy's ongoing commitment to prevent and relieve pain and suffering during serious illness.

Carnegie Mellon system thwarts Internet eavesdropping
The growth of shared Wi-Fi and other wireless computer networks has increased the risk of eavesdropping on Internet communications, but researchers at Carnegie Mellon University's School of Computer Science and College of Engineering have devised a low-cost system that can thwart these "Man-in-the-Middle" (MitM) attacks.

Women may stop anticoagulants after blood clots
Women may safely discontinue oral anticoagulants (blood thinners) after 6 months of treatment following a first unprovoked venous blood clot (thromboembolism) if they have no or one risk factor.

Looking beyond the drug receptor for clues to drug effectiveness
Antipsychotic drugs that are widely used to treat schizophrenia and other problems may not work as scientists have assumed, according to findings from Duke University Medical Center researchers that could lead to changes in how these drugs are developed and prescribed.

Normalizing tumor vessels to improve cancer therapy
Chemotherapy drugs often never reach the tumors they're intended to treat, and radiation therapy is not always effective, because the blood vessels feeding the tumors are abnormal-"leaky and twisty" in the words of the late Judah Folkman, MD, founder of the Vascular Biology program at Children's Hospital Boston.

'Perfect pitch' in humans far more prevalent than expected
Researchers at the University of Rochester's Eastman School of Music and Department of Brain and Cognitive Sciences have developed a unique test for perfect pitch, and have found surprising results.

New findings explain genetic disorder's unique shift
Findings reported in this month's issue of PLoS Biology give insight into the unique characteristics of the birth defect known as Prader-Willi Syndrome (PWS), and at the same time, may help explain the way that a certain type of gene is expressed in all humans.

CSHL scientists identify new drug target against virulent type of breast cancer
Tumor cells in a particular subset of breast cancer patients churn out too much of a protein called ErbB2 -- also often called HER2 -- which drives the cells to proliferate unchecked. Patients unlucky enough to be in this group -- about one in four -- have poorer prognoses and clinical outcomes than those who don't.

Potential diabetes treatment selectively kills autoimmune cells from human patients

AgriLife Research breeder develops drought-tolerant corn
At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist.
