Scientists from the Jupiter campus of the Scripps Research Institute have shown a novel way to dramatically raise the potency of drug candidates targeting RNA, resulting in a 2,500-fold improvement in potency and significantly increasing their potential as therapeutic agents. Fuente :...

More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience. The discovery provides scientists with another piece of the mercury puzzle, bringing them one step closer to understanding the challenges associated...

A group of pediatric surgeons at hospitals around the country have designed a system to collect and analyze data on surgical outcomes in children -- the National Surgical Quality Improvement Program is the first national database able to reliably compare outcomes among different hospitals where...

Screening everyone for HIV in the emergency department may be superior to testing only those with apparent risk, when trying to identify patients with undiagnosed HIV infection, according to a new results by researchers at the University of Cincinnati and published in the Journal of Acquired Immune Deficiency Syndromes.

Molecules could soon be "scanned" in a fashion similar to imaging screenings at airports, thanks to a detector developed by University of Pittsburgh physicists. Fuente : http://www.eurekalert.org/pub_releases/2013-08/uop...

Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging...

Proteins are the workhorses of cells, adopting conformations that allow them to set off chemical reactions, send signals and transport materials. But when a scientist is designing a new drug, trying to visualize the processes inside cells, or probe how molecules interact with each other, they can't always find a protein that...

Tropical Depression Gil has been weakening for a couple of days, while Tropical Storm Henriette appears to be strengthening in the Eastern Pacific Ocean. NOAA's GOES-15 satellite captured both storms in one image that clearly showed Henriette was the larger storm, and NASA's Aqua satellite peered under Henriette's clouds to...

Researchers at the Harvard School of Engineering and Applied Sciences have developed a way for photographers and microscopists to create a 3D image through a single lens -- i.e. a regular camera or microscope -- without moving the camera. This improbable-sounding technology relies only on...

Researchers at Mayo Clinic in Florida have revealed the process by which chronic inflammation of the pancreas, pancreatitis, morphs into pancreatic cancer. Fuente : http://www.eurekalert.org/pub_releases/2013-08/mc-...

Climate changes how species interact with one another -- and not just today. Scientists are studying trends from fossil records to understand how climate change impacted the world in the ancient past and to identify ways to predict how things may change in the future, according to a new study published in the Aug. 2 issue of...

In a study carried out at the University of Eastern Finland, bone histomorphometry and infrared spectroscopy revealed abnormal bone properties in children with vertebral fractures and in children after solid organ transplantation. Bone compositional changes in children with vertebral fractures and after different types of organ...

Mothers who breastfeed their children may have a lower risk of developing Alzheimer's Disease, with longer periods of breastfeeding also lowering the overall risk, a new study suggests. Fuente : http://www.eurekalert.org/pub_releases/2013-08/uoc...

Chronic harvesting of a tropical tree that many local communities in Western Africa depend on can alter the tree's reproduction and drastically curtail fruit and seed yields over the tree's lifetime, according to a new study. Fuente : http://www.eurekalert.org/pub_releases/2013-08/nif...

White Americans who are obese are twice as likely as black Americans to have surgery to tackle the problem, a study has found. Fuente : http://www.eurekalert.org/pub_releases/2013-08/icl...

Scientists at the University of East Anglia have shown that sequencing the DNA of crushed up creepy crawlies can accelerate the monitoring and cataloging of biodiversity around the world. Research published today shows that a process known as "metabarcoding" is much faster than and just as reliable as standard biodiversity...

Scientists have determined the structure of NatA, an enzyme complex that modifies one end of most human proteins and is made at elevated levels in numerous forms of cancer. Their findings, they believe, will allow them to create an inhibitor -- a potential drug -- that could knock out NatA in order...

Chemically modified inhibitors of the COX-2 enzyme relieve anxiety behaviors in mice by activating natural "endocannabinoids" without gastrointestinal side effects, scientists report. Endocannabinoids are natural signaling molecules that activate cannabinoid receptors in the brain, the same...

Researchers have deciphered how oxytocin, acting as a neurohormone in the brain, not only reduces background noise, but more importantly, increases the strength of desired signals. These findings may be relevant to autism, which affects one in 88 children in the United States. Fuente :...
