Women with moderate to severe menstrual cramps may find relief in a class of erectile dysfunction drugs, according to a team of researchers led by Penn State College of Medicines Richard Legro. Primary dysmenorrhea, also called PD, is the most common cause of pelvic pain in women. Show More Summary
Coffee and beer are polar opposites in the beverage world -- coffee picks you up, and beer winds you down. Now researchers have discovered that the beverages may also have opposite effects on your genome. Working with a kind of yeast...Show More Summary
LA JOLLA, CA—December 5, 2013—Avian influenza virus H7N9, which killed several dozen people in China earlier this year, has not yet acquired the changes needed to infect humans easily, according to a new study by scientists at The Scripps Research Institute (TSRI). Show More Summary
Hummingbird metabolism is a marvel of evolutionary engineering. These tiny birds can power all of their energetic hovering flight by burning the sugar contained in the floral nectar of their diet. Now new research from the University...Show More Summary
For the first time, scientists have measured the frictional heat produced by the fault slip during an earthquake. Their results, published December 5 in Science, show that friction on the fault was remarkably low during the magnitude 9.0 Tohoku-Oki earthquake that struck off the coast of Japan in March 2011 and triggered a devastating tsunami. read more
Geoscientists estimate that the New Jersey shore will likely experience a sea-level rise of about 1.5 feet by 2050 and of about 3.5 feet by 2100 -- 11 to 15 inches higher than the average for sea-level rise globally over the century...
The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today's supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. Show More Summary
Genomes must be replicated in two copies during cell division. This process occurs at structures called 'replication forks', which are equipped with enzymes and move along the separated DNA strands. In tumour cells, the replication forks are frequently damaged, giving rise to breaks in the double-stranded DNA. Show More Summary
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics -- so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."
A team of scientists, led by principal investigator Paul S. Mischel, MD, a member of the Ludwig Institute for Cancer Research and professor in the Department of Pathology at the University of California, San Diego School of Medicine,...Show More Summary
Autism spectrum disorder (ASD) is diagnosed when individuals exhibit characteristic behaviors, decreased social interactions, and impaired communication. Curiously, many with ASD also suffer from gastrointestinal issues, like abdominal cramps and constipation. Show More Summary
University of Iowa researchers may have come up with the right matchmaking formula for online dating sites: Pair people according to their past interests and online mating success, rather than who they say they're interested in. read more
The devastating tsunami that struck Japan's Tohoku region in March 2011 was touched off by a submarine earthquake far more massive than anything geologists had expected in that zone. Now, a team of scientists including McGill University...Show More Summary
Scientists have found that the very receptors in the mosquito's maxillary palp that detect carbon dioxide are ones that detect skin odors as well, thus explaining why mosquitoes are attracted to skin odor -- smelly socks, worn clothes, bedding -- even in the absence of carbon dioxide.

ITHACA, N.Y. — Despite widespread fascination with sharks, the world's oldest ocean predators have long been a genetic mystery. The first deep dive into a great white shark's genetic code has fished up big surprises behind a design so...Show More Summary
Astronomers have discovered the most distantly orbiting planet found to date around a single, sun-like star. Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b is unlike anything in our own Solar System and defies current planet formation theories.
CORVALLIS, Ore. – An international team of scientists that installed a borehole temperature observatory following the 2011 Tohoku-Oki earthquake in Japan has been able to measure the "frictional heat" generated during the rupture ofShow More Summary
