Making days longer than 24 hours
People at a research hospital in Boston have been living 24-hour, 39-minute days. They were part of an experiment to show that the 24-hour human sleep-wake cycle can be adapted to other biological rhythms like the longer days on Mars.
Pioneering study maps attention, memory and language links in the human brain
A University of Arizona scientist who has specialized in studying how fireflies and other creatures communicate has won a million-dollar grant to conduct a pioneering 5-year study on the roles that attention and memory play when the human brain hears and processes spoken language.
Biologists reveal neuronal channel that regulates breathing
Biologists at the University of Pennsylvania have found a link between a recently discovered protein in the brain and the nervous system's duty to regulate respiration.
Students devise oral quick-dissolve strips for rotavirus vaccine
A thin strip that dissolves in the mouth like a popular breath-freshener could someday provide life-saving rotavirus vaccine to infants in impoverished areas. The innovative drug-delivery system was developed by Johns Hopkins undergraduate biomedical engineering students.
Growing nerve cells in 3-d dramatically affects gene expression
When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes.
Bigger is smarter
When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species' body size may be a mistake. The findings were reported by researchers at Grand Valley State University and the Anthropological Institute and Museum at the University of Zürich, Switzerland. The study has now been published online in the journal Brain, Behavior, and Evolution.
'Star trek'-type scanning may reveal genetic activity of tumors
Peering into the body and visualizing its molecular secrets, once the stuff of science fiction, is one step closer to reality with a study from researchers at the Stanford University School of Medicine and the University of California, San Diego School of Medicine.
'Supersize me' mice research offers grim warning for america's fast food consumers
It's research that may have you thinking twice before upgrading to the large size at your favorite fast food joint. Saint Louis University research presented in Washington, D.C., shows the dangers of high-fat food combined with high fructose corn syrup and a sedentary lifestyle – in other words, what may be becoming commonplace among Americans.
Babies able to tell through visual cues when speakers switch languages
At four months, babies can tell whether a speaker has switched to a different language from visual cues alone, according to a University of British Columbia study.
Gene thought to assist chemo may help cancer thrive
A gene thought to be essential in helping chemotherapy kill cancer cells, may actually help them thrive. In a new study of chemo patients, scientists at the Georgia Institute of Technology and the Ovarian Cancer Institute found that 70 percent of subjects whose tumors had mutations in the gene p53 were still alive after five years. Patients with normal p53 displayed only a 30 percent survival rate. The findings raise the possibility of a new strategy for fighting cancer - namely, developing drugs to disable the functioning of this gene in the tumors of patients undergoing chemotherapy.

Study reveals why bad things happen inside the brain when we inhale pure oxygen
It's a scenario straight out of "Grey's Anatomy"— a paramedic or doctor plops a mask over the face of a person struggling to breathe and begins dispensing pure oxygen.
Wearable technology helps monitor mental illness
Psychiatric researchers at the University of California, San Diego (UCSD) School of Medicine reported important new findings from a study of patients with bipolar affective disorder and schizophrenia at the upcoming meeting of the Society of Biological Psychiatry.
Skip buying extra stuff and take a vacation instead
Shopping for that new high-definition television this summer? Skip it, and take a vacation instead, says a University of Colorado at Boulder psychologist who studies happiness.
An apple peel a day might keep cancer at bay
An apple a day keeps the doctor away? Or, what appears to be more accurate: An apple peel a day might help keep cancer at bay, according to a new Cornell study.
The scientist and the contortionist
Watching a ballet dancer or circus acrobat perform, who hasn't winced at the thought of trying to replicate the impossible flexibility on display? Emilie Mackie '07, a neuroscience major, wondered what exactly is happening to the brain during this type of visceral response to someone else's physical state, so she cast about for a contortionist.
Children can perform approximate math without arithmetic instruction
Children are able to solve approximate addition or subtraction problems involving large numbers even before they have been taught arithmetic, according to a study conducted at Harvard University by researchers from the University of Nottingham and Harvard.
Human antibodies protect mice from avian flu
An international team of scientists, including researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, report using antibodies derived from immune cells from recent human survivors of H5N1 avian influenza to successfully treat H5N1-infected mice as well as protect them from an otherwise lethal dose of the virus.
Brain activity reflects differences in types of anxiety
All anxiety is not created equal, and a research team at the University of Illinois now has the data to prove it. The team has found the most compelling evidence yet of differing patterns of brain activity associated with each of two types of anxiety: anxious apprehension (verbal rumination, worry) and anxious arousal (intense fear, panic, or both).
DNA-damage test could aid drug development
In the daunting marathon that leads to successful drugs, promising drug candidates must pass toxicity tests before entering clinical trials. Researchers from MIT and the Whitehead Institute have developed a cell culture test for assessing a compound's genetic toxicity that may prove dramatically cheaper than existing animal tests. This assay would allow genetic toxicity to be examined far earlier in the drug development process, making it much more efficient.
Research links brain chemistry with aggressive personality
An image depicting research findings linking brain chemistry with aggressive personality has been named "2007 Image of the Year" by the Society for Nuclear Medicine (SNM). The research, which was performed at the U.S. Department of Energy's Brookhaven National Laboratory, showed that healthy men with lower levels of a particular brain enzyme exhibited more aggressive personality traits, as measured by a standard personality questionnaire.
