Imagine having arthritis in your jaw bones ... if they're over 2 meters long! A new study has found signs of a degenerative condition similar to human arthritis in the jaw of a pliosaur, an ancient sea reptile that lived ...

During the 2008 Beijing Olympics, changes in air pollution were associated with changes in biomarkers of systemic inflammation and thrombosis (formation of blood clot) as well as measures of cardiovascular physiology in healthy young persons, according to a new study. ...

A drug made from the saliva of the Gila monster lizard is effective in reducing the craving for food. Researchers have tested the drug on rats, who after treatment ceased their cravings for both food and chocolate. ...

A new study is the first to show how a diet steadily high in fructose slows the brain, hampering memory and learning -- and how omega-3 fatty acids can minimize the damage. ...

Surgeons have restored some hand function in a quadriplegic patient with a spinal cord injury at the C7 vertebra, the lowest bone in the neck. Instead of operating on the spine itself, the surgeons rerouted working nerves in the upper ...

Scientists have discovered that mice that lack a gene called Snf2l have brains that are 35 percent larger than normal. The research could lead to new approaches to stimulate brain regeneration and may provide important insight into developmental disorders such ...

In its early years, information theory was dominated by research on error-correcting codes: How do you encode information so as to guarantee its faithful transmission, even in the presence of the corrupting influences engineers call "noise"? Recently, one of the ...

A new study suggests that the guidelines governments use to determine when to evacuate people following a nuclear accident may be too conservative. ...

Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and "personalized medicine" tailored to the specific biochemistry of individual patients. ...

Amber from the Cretaceous period found in Spain has revealed the first ever fossil record of insect pollination. Scientists discovered and studied with X-rays at the ESRF a specimen of a tiny insect covered with pollen grains. This is the ...

A novel mechanism for anxiety behaviors, including a previously unrecognized inhibitory brain signal, may inspire new strategies for treating psychiatric disorders, researchers report. By testing the controversial role of a gene called Glo1 in anxiety, scientists uncovered a new inhibitory ...

Child abuse or neglect are strong predictors of major health and emotional problems, but little is known about how the chronicity of the maltreatment may increase future harm apart from other risk factors in a child's life. Scientist have now ...

Our decisions to trust people with our money are based more on how they look then how they behave, according to new research. ...

A DNA-covered submicroscopic bead used to deliver genes or drugs directly into cells to treat disease appears to have therapeutic value just by showing up, researchers report. ...

Medical researchers have identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease. ...

Scientists have identified how skeletal muscle stem cells respond to muscle injury and may be stimulated to improve muscle repair in Duchenne Muscular Dystrophy, a severe inherited disease of muscle that causes weakness, disability and, ultimately, heart and respiratory failure. ...

Researchers have identified a new biomarker and therapeutic target for pancreatic cancer, an often-fatal disease for which there is currently no reliable method for early detection or therapeutic intervention. ...

For the first time, researchers have been able to combine different climate models using spatial statistics - to project future seasonal temperature changes in regions across North America. ...

Food allergies pose a serious and growing problem in the West. Many foods can lead to allergic reactions and this situation is further complicated by so-called cross-reactions, whereby an allergy to one particular food can trigger allergic reactions to another ...

A new study consisting of inducing cells to express telomerase, the enzyme which -- metaphorically -- slows down the biological clock -- was successful. The research provides a "proof-of-principle" that this "feasible and safe" approach can effectively "improve health span." ...
