A new UCSF study shows that overweight and obese women who suffer from hot flashes can reduce the severity of their hot flashes if they lose weight through diet or exercise.

Disruption of two genes that control circadian rhythms can lead to diabetes, a researcher at UT Southwestern Medical Center has found in an animal study.

A new collection of some of North America's hottest foods -- an eclectic range of New World chili peppers -- were delivered to the cool Arctic Circle environs of the Svalbard Global Seed Vault this week, where their exotic tongue-scorching qualities can be kept safe for centuries.

A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters.

The same molecular mechanism that increases life span through calorie restriction may help boost memory and brainpower, researchers at MIT's Picower Institute for Learning and Memory report in the July 11 issue of Nature.

New research being presented today at the UK National Stem Cell Network Annual Science Meeting in Nottingham shows that adding fat to mouse stem cells grown in the lab affects their response to the signals that push them to develop into one or other of the main types of fat storage cells -- subcutaneous (under the skin) or visceral (around the organs).

Professor Fiona Watt will today give the Anne McLaren Memorial Lecture at the UK National Stem Cell Network annual science meeting and will detail a new approach to screening for drugs that target stem cells. To begin with, this is being developed for adult skin stem cells, giving hope for new drugs to promote wound healing and aid the use of stem cells to, for example, treat severe burns.

Dr. Andrew Johnson is speaking today at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells -- research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies.

Scientists at Cold Spring Harbor Laboratory and California-based Isis Pharmaceuticals have succeeded in reversing symptoms of type III SMA, a relatively mild form of spinal muscular atrophy, in mice by introducing chemically modified RNA pieces called ASOs into their spinal cords. The ASOs fix the molecular mistake underlying SMA by redirecting a cellular editing process called alternative splicing.

Asthma is the most common complication of pregnancy in Australia with harmful effects on babies, but many of these could be prevented a University of Adelaide researcher says.

Researchers at Mathematics Research Centre and Universitat Autonoma de Barcelona have discovered the mathematical relation between the number of hurricanes produced in certain parts of the planet and the energy they release.

Pfizer today announced that the results of a number of hemophilia studies will be presented at the World Federation of Hemophilia (WFH) 2010 Congress taking place July 10-14, 2010, in Buenos Aires, Argentina. Key research includes a pre-clinical evaluation of recombinant factor Xa as a potential new approach to restoring hemostasis, as well as a study assessing the potential for an engineered recombinant factor VIIa molecule to improve therapeutic outcomes in mouse models of hemophilia.

A study of 690,000 children found extremely obese children have a 40 percent higher risk of gastroesophageal reflux disease and moderately obese children have a 30 percent higher risk of GERD compared to normal weight children.This large population-based study establishes an association between obesity and GERD in children, an association previously reported in adults. GERD leads to chronic respiratory conditions, and increased risk for esophageal cancer, the nation's fastest growing cancer.

An ultra-low-molecular-weight heparin called semuloparin has been found to reduce the incidence of venous thromboembolism in orthopedic surgery patients

Chang Lu and his chemical engineering research group at Virginia Tech have discovered how to "greatly enhance" the delivery of DNA payloads into cells. The description of their work will be featured on the cover of Lab on a Chip, the premier journal for researchers in microfluidics. The work also appears in the July 8 issue of Nature magazine.
