Cancer cure in mice to be tested in humans
Scientists at Wake Forest University Baptist Medical Center are about to embark on a human trial to test whether a new cancer treatment will be as effective at eradicating cancer in humans as it has proven to be in mice.
New map ids the core of the human brain
An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex -- the outer layer of the brain responsible for higher level thinking -- connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to the workings of both hemispheres of the brain.
Cancer cells revert to normal at specific signal threshold
Cancer starts when key cellular signals run amok, driving uncontrolled cell growth. But scientists at the Stanford University School of Medicine report that lowering levels of one cancer signal under a specific threshold reverses this process in mice, returning tumor cells to their normal, healthy state. The finding could help target cancer chemotherapy to tumors while minimizing side effects for the body's healthy cells.
When using gestures, rules of grammar remain the same despite speakers' language
The mind appears to have has a consistent way of organizing an event that defies the order in which subjects, verbs, and objects typically appear in languages, according to research at the University of Chicago.
Post-exercise caffeine helps muscles refuel
Recipe to recover more quickly from exercise: Finish workout, eat pasta, and wash down with five or six cups of strong coffee.
Parasite vaccines within reach
Even though parasites are complex creatures, the mammalian immune response to them is surprisingly simple, leading University of California, Berkeley, researchers to predict that creating vaccines for parasitic diseases such as malaria may be more straightforward than initially thought.
New titanium coating improves joint replacements
Research at the Georgia Institute of Technology shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone.
Smart contact lenses
"Smart" contact lenses that measure pressure within the eye and dispense medication accordingly could be made possible using a new material developed by biomedical engineers at UC Davis.
Exercise in a pill
Trying to reap the health benefits of exercise? Forget treadmills and spin classes, researchers at the Salk Institute for Biological Studies may have found a way around the sweat and pain. They identified two signaling pathways that are activated in response to exercise and converge to dramatically increase endurance.
Low-gravity training machine reduces joint, muscle impacts on runners by half
A University of Colorado at Boulder study of a space-age, low-gravity training machine used by several 2008 Olympic runners showed it reduced impacts on muscles and joints by nearly half when subjects ran at the equivalent of 50 percent of their body weight.

Hypnosis shown to reduce symptoms of dementia
A scientist at the University of Liverpool has found that hypnosis can slow down the impacts of dementia and improve quality of life for those living with the condition.
OSU study shows exposure to bad air raises blood pressure
The air people breathe while walking in the park, working in the garden or shopping downtown may be unhealthy enough to seriously spike their blood pressure, a new study suggests.
Whom do we fear or trust? Faces instantly guide us, scientists say
What's in a face? Plenty, according to scientists at Princeton University. A pair of Princeton psychology researchers has developed a computer program that allows scientists to analyze better than ever before what it is about certain human faces that makes them look either trustworthy or fearsome. In doing so, they have also found that the program allows them to construct computer-generated faces that display the most trustworthy or dominant faces possible.
Not quite a teen, not fully an adult
Fueled by hormone fluctuations, the teenage years can be a time of huge emotional upheaval. But, as an initiative by MIT's Young Adult Development Project finds, the roller coaster may not end at the 18th birthday.
Alzheimer's disease patients show improvement in trial of new drug
A new drug has been shown to improve the brain function of people with early stage Alzheimer's disease and reduce a key protein associated with the disease in the spinal fluid, in a small study published in the journal Lancet Neurology and presented at the 2008 Alzheimer's Association International Conference on Alzheimer's Disease.
Daily walk can help control diabetes
Just an extra 45 minute walk a day can help people control Type 2 diabetes, according to a new study at Newcastle University.
Why the slow paced world could make it difficult to catch a ball
BBSRC researchers at the University of Birmingham have uncovered new information about the way that we perceive fast moving, incoming objects - such as tennis or cricket balls. The new research, published in the Proceedings of the National Academy of Sciences (PNAS), studies why the human brain has difficulty perceiving fast moving objects coming from straight ahead; something that should be a key survival skill.
Vitamin C injections slow tumor growth in mice
High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences. The researchers traced ascorbate's anti-cancer effect to the formation of hydrogen peroxide in the extracellular fluid surrounding the tumors. Normal cells were unaffected.
Parents shape whether their children learn to eat fruits and vegetables
Providing fruits for snacks and serving vegetables at dinner can shape a preschooler's eating patterns for his or her lifetime.
Songbirds may hold key to advances in treatment of brain degeneration
NIH-funded research being conducted by Lehigh's Colin Saldanha is exploring how hormones affect learning, memory and brain function.
