2 types of stem cells are similar
Researchers saw substantial similarity between the two stem-cell types - pluripotent stem cells and embryonic stem cells, reported in a new study.

Good grades in high school lead to better health
The "A" grades that high schoolers earn aren't just good for making the honor roll - they also make them healthier as adults, too.

Inherited brain activity predicts childhood anxiety risk
A new study focused on anxiety and brain activity pinpoints the brain regions that are relevant to developing childhood anxiety.

Virus hybridization could create pandemic bird flu
Genetic interactions between avian H5N1 influenza and human seasonal influenza viruses have the potential to create hybrid strains combining the virulence of bird flu with the pandemic ability of H1N1, according to a new study.

Breast cancer drugs may prevent cervical cancer also
Researchers eliminated cervical cancer in mice with two FDA-approved drugs currently used to treat breast cancer and osteoporosis. The study is published in the Proceedings of the National Academy of Sciences.

Low calorie diet may slow aging
A nutritious and low calorie diet blunts aging and significantly delays the onset of such age-related disorders as cancer, diabetes, cardiovascular disease and brain atrophy, revealed by researchers.

Scientists isolate genes that made 1918 flu lethal
By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.

Genetic disease recreated in lab
When neurons started dying in Clive Svendsen's lab dishes, he couldn't have been more pleased. The dying cells – the same type lost in patients with the devastating neurological disease spinal muscular atrophy – confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient.

Heart tissue can be saved after heart attacks
A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.

Brain pathway responsible for obesity discovered
University of Wisconsin-Madison researchers, for the first time, have found a messaging system in the brain that directly affects food intake and body weight.

Brain strong during waking hours, weaken during sleep
Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more, and several hours of sleep will refresh it. Now new research from the University of Wisconsin School of Medicine and Public Health clarifies this phenomenon, supporting the idea that sleep plays a critical role in the brain's ability to change in response to its environment. This ability, called plasticity, is at the heart of learning.

Ebola virus disarmed by excising a single gene
The deadly Ebola virus, an emerging public health concern in Africa and a potential biological weapon, ranks among the most feared of exotic pathogens. Due to its virulent nature, and because no vaccines or treatments are available, scientists studying the agent have had to work under the most stringent biocontainment protocols, limiting research to a few highly specialized labs and hampering the ability of scientists to develop countermeasures.
