Sedentary mice given the drug ran longer without training.

Researchers investigated which commonly recommended first aid actions are the most effective for Physalia, man 'o war jellyfish, stings. They found the best first aid is to rinse with vinegar to remove any residual sting...

New research has provided the first evidence that viruses and hosts share highly similar regulatory sequences in their promoters -- the initiation sequences of human genes that code for functional proteins.

In this first ever molecular drug-imaging study in children, researchers used whole-body positron emission tomography/computed tomography (PET/CT) scans to determine whether bevacizumab (Avastin) treatment of diffuse int...

In balancing speed and accuracy to duplicate DNA and produce proteins, researchers find evolution determined that speed is favored much more.

Scientists have discovered why some cancers may reoccur after years in remission. Importantly, the scientists demonstrated that the escaping tumor cells reach the bloodstream by entering blood vessels deep within the den...

Researchers have successfully developed a method to grow inner ear tissue from human stem cells, a finding that could lead to new platforms to model disease and new therapies for the treatment of hearing and balance diso...

The black bear population in southern New York has grown and expanded its range since the early 1990s, which has led to increased encounters with humans.

Knowing the signs of becoming drowsy behind the wheel, many of which are similar to distracted and drunk driving, could potentially be lifesaving.

Pancreatic beta cells help maintain normal blood glucose levels by producing the hormone insulin -- the master regulator of energy (glucose). Impairment and the loss of beta cells interrupts insulin production, leading t...

Nonalcoholic fatty liver disease (NAFLD) -- a condition that can lead to liver cirrhosis and cancer -- isn't typically detected until well advanced. Even then, diagnosis requires a biopsy. To more easily detect NAFLD, re...

A hormone called FGF21 that is secreted by the liver after eating sweets may determine who has a sweet tooth and who doesn't, according to a new study. Researchers found that people with particular variants of the FGF21 ...

Implementation of policies at academic medical centers that restricted pharmaceutical detailing (pharmaceutical representative sales visits to physicians) was associated with modest but significant reductions in prescrib...

Specific genetic changes in the placentas of women who gave birth to growth-restricted infants have been discovered by researchers. Up to 10 percent of pregnancies worldwide are affected by intrauterine growth restrictio...

Amantadine hydrochloride may be the most common medication you've never heard of. Now, chemists have published the very first data on this important chemical's thermodynamic properties, including data on how it responds ...

Using two simple blood tests, researchers were able to drastically improve treatment for resistant hypertension across three sites in Nigeria, Kenya and South Africa. The study demonstrates that for patients in Africa wi...

The US space agency's involvement with the ISS is funded until 2024, but it might run out of space suits before then, despite spending $200 million on new designs

A 145-million-year-old dinosaur about the size of a wild turkey sported a plume of tail feathers that were surprisingly modern-looking and aerodynamic in shape, a new study finds.

According to the Fermi LAT collaboration, the galaxy's excessive gamma-ray glow likely comes from pulsars, the remains of collapsed ancient stars. A mysterious gamma-ray glow at the center of the Milky Way is most likely...

Kidney cancer patients may soon have more treatment choices that provide a higher quality of life, thanks to new research. A recent study showed that treating metastatic kidney cancer with an advanced and focused form of...

Researchers have developed an innovative fruit fly-based model of the types of harmful cysts that can form on kidneys. The model has enormous potential for assisting the study of how cells proliferate in polycystic kidne...

Bacteria need mutations -- changes in their DNA code -- to survive under difficult circumstances. When necessary, they can even mutate at different speeds. The findings open up various new avenues for research, ranging f...
