How protein-rich diets curb hunger
... a study of rats, Mithieux and colleagues made the surprising discovery that diets heavy in protein spark the production of glucose in the small intestine. That rise in glucose, sensed in the liver and relayed to the brain, led the animals to eat less, they reported. "The current findings provide an answer to t...The brain is broadly wired for reproduction
...ation back to those relay areas," said Buck. "This surprising finding suggests that the GnRH neurons are influencing the processing of odor and pheromone signals in the brain. It may be the brain's way of saying whether or not it wants to receive particular sensory information -- depending on the reproductive c...New marine research shows global warming may affect organic matter recycling differently
...cademy of Natural Sciences in Philadelphia. "These surprising results show that temperature dependence strongly affects the efficiency of organic matter breakdown and need to be taken into account in models of the role of sediments in the global carbon cycle," said Paul Kemp, program director in the National Sc...Other highlights in the November 16 JNCI

However, the observation that hysterectomy prevalence is higher among young blacks compared with whites suggests that hysterectomy prevalenc...Innovative research set to push boundaries of cancer care

Based on this novel and surprising discovery, a team of researchers has shown that P. aeruginosa preferentially enters human melanoma and breast cancer cells, triggering apoptotic cell death. They further discovered that azurin sets off this death sequence by forming a complex with th...War on terror meets war on cancer

That conclusion was based on their surprising discovery that water inside the bacterial cells (intracellular water) has a different oxygen-18-to-oxygen-16 ratio than water outside the cells (extracellular water). "We've shown a significant portion of the water inside the bacteria can come from ...AKT cancer cell pathway demonstrates unexpected function
...er parts of the body researchers have uncovered a surprising role for the AKT/PKB (protein kinase B) enzyme, providing important new insights into cancer metastasis and suggesting that current efforts to develop cancer therapies by inhibiting AKT may be inadvertently promoting the spread of the disease.

The discovery also suggests a new avenue for the treatment of hereditary hemochromatosis, an iron-overload disease that is one of the most common genetic disorders among Caucasian...ORNL-led study shows forests thrive with increased CO2 levels

Researchers analyzed data from four experiments in which young forest stands were exposed for multiple years to an atmosphere with a carbon dioxide concent...New research examines genetics of successful aging

"It would not be surprising if the collection of genes that influences the capacity to reach old age with normal mental capacity differs somewhat for men and women." The results of the study also highlighted the detrimental effects of cigarette smoking and excessive drinking ...Another world-record achievement for National High Magnetic Field Laboratory

The research team used a computational approach to demonstrate that an unprecedented 50 perecent of the bone DNA was...Light-sensing cells in retina develop before vision
...GCs) are active and functioning at birth. That was surprising because the mouse retina doesn't develop fully until a mouse is almost three weeks old, and the first rod cells don't appear until about 10 days after birth.

In this study, Tudor-SN was found to be responsible for degrading miRNAs that had ...Research tracks whales by listening to sounds

Sperm whales, for example, have been detected in the Gulf of Alaska year-round, although this species has been generally thought to migrate to midlatitudes in winter. And critically endangered North Pacific right whales hav......coustic neuroma by one-and-a-half times.
