Among adults without diabetes, quitting smoking, compared with continuing smoking, was associated with a lower risk of cardiovascular disease despite subsequent weight gain, according to a new study.

Brain imaging soon after mild traumatic brain injury (mTBI) or mild concussion can detect tiny lesions that may eventually provide a target for treating people with mTBI.

Vincetoxicum rossicum, commonly known as dog-strangling vine, is an alien invasive plant from the Ukraine and southwestern Russia that has now established itself in the northeastern United States and southern Ontario, Canada. This species successfully displaces local native plants, demonstrating high tolerance for environmental variables such as light and soil moisture.

Acute kidney injury, a common and serious complication of hospitalization, is on the increase worldwide, affecting an estimated 6 percent of all hospitalized patients and 30-40 percent of adults and children having cardiopulmonary bypass surgery.

Among other tragedies in countries with HIV epidemics, political violence can have the additional long-term consequence of an increase in viral resistance to treatment and HIV treatment failure, say experts. The researchers, who have studied post-strife treatment failure and resistance in Kenya, argue that officials and health care providers need to study and prepare for how violence disrupts antiretroviral treatment and complicates the epidemic.

Mouse model studies show that administered genetically or topically, protein Smad7 protects against or heals mouth sores commonly associated with cancer treatment.

Children with an autism spectrum disorder may be at greater risk for contemplating suicide or attempting suicide than children without autism, according to researchers.

The number of potentially habitable planets is greater than previously thought, according to a new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars.

Female professors are underrepresented on corporates science advisory boards, and the gender gap decreases when academic administrators work to raise the profile of their high-performing female scientists.

Children as young as 3 years old know when they are not sure about a decision, and can use that uncertainty to guide decision making, according to new research.

New hope for reversing the effects of spinal cord injury may be found in a combination of stem cell therapy and physical therapy according to new findings.

It is possible to hide secret messages in simple jokes, according to new research.

A new study shows that bitter melon juice restricts the ability of pancreatic cancer cells to metabolize glucose, thus cutting the cells' energy source and eventually killing them.

A twist on thin-film technology may provide a way to optically detect and analyze multiple substances simultaneously, leading to quicker diagnostics in such industries as health care and homeland security, according to researchers.

Ongoing glacier loss in the Canadian high Arctic is accelerating and probably irreversible, new model projections suggest. The Canadian high Arctic is home to the largest clustering of glacier ice outside of Greenland and Antarctica -- 146,000 square kilometers (about 60,000 square miles) of glacier ice spread across 36,000 islands.

Scientists have for the first time documented detailed records of dinosaur egg fossils in the Coll de Nargó archaeological site in Lleida, Spain. Up until now, only one type of dinosaur egg had been documented in the region.

Alex Pyron's expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles.

Dr. Sharon Toker of Tel Aviv University has found a link between job burnout and coronary heart disease (CHD), the buildup of plaque in the coronary arteries that leads to angina and heart attacks. She says that her findings were more extreme than she expected and make burnout a stronger predictor of CHD than many other risk factors.

Patients who receive hemodialysis are at a significant risk of developing infections, a leading cause of hospitalization and death in this patient population. A new study highlights the need to improve antibiotic use in outpatient dialysis facilities as data shows nearly a third of antibiotic prescriptions are deemed inappropriate.

New research reveals that B cells regulate obesity-associated inflammation and type 2 diabetes through two specific mechanisms. The study indicates the importance of continuing to explore B cells as a therapeutic target to treat these diseases.
