First horned dinosaur from Mexico: Plant-eater had largest horns of any dinosaur Posted: 29 May 2010 02:00 PM PDT A new species of horned dinosaur unearthed in Mexico has larger horns that any other species -- up to 4 feet long -- and has given scientists fresh insights into the ancient history of western North America, according to paleontologists.

Experimental treatment protects monkeys from lethal Ebola virus post-exposure Posted: 29 May 2010 02:00 PM PDT Scientists using tiny particles of genetic material to interfere in the replication process of the deadly Ebola virus have successfully prevented monkeys exposed to that virus from dying of hemorrhagic fever. The proof-of-concept study suggests that such protection also should be possible in humans.

Snails on methamphetamine: Memories formed by snails under influence of meth are harder to forget Posted: 29 May 2010 02:00 PM PDT Crystal meth (methamphetamine) is a highly addictive drug, which improves memory, but once hooked, addicts find the habit hard to break. One researcher wondered whether she could learn more about the effects of meth by studying the effect it has pond snail's memories. She found that memories formed by snails under the influence of meth are harder to forget and could help us understand human addiction.

Novel protein essential for successful pregnancy Posted: 29 May 2010 02:00 PM PDT Researchers have helped clarify the function of a unique protein called preimplantation factor, which is produced by healthy embryos to direct embryo attachment and help the mother adapt to pregnancy.

Researcher decodes Rembrandt's 'magic' Posted: 29 May 2010 02:00 PM PDT A researcher using computer-rendering programs has uncovered what makes Rembrandt's masterful portraits so appealing. Rembrandt may have pioneered a technique that guides the viewer's gaze around a portrait, creating a special narrative and "calmer" viewing experience.

Clue to origin of Milky Way gas clouds discovered Posted: 29 May 2010 08:00 AM PDT A study of hydrogen gas clouds in two different regions of the Milky Way shows that they are much more abundant above areas of intense star formation, indicating they are blown away from the Galaxy's plane by stellar winds and supernova explosions.

Cold sore virus may contribute to cognitive and brain abnormalities in schizophrenia Posted: 29 May 2010 08:00 AM PDT Exposure to the common virus that causes cold sores may be partially responsible for shrinking regions of the brain and the loss of concentration skills, memory, coordinated movement and dexterity widely seen in patients with schizophrenia, according to research led by Johns Hopkins scientists.

Deep subduction of the Indian continental crust beneath Asia Posted: 29 May 2010 08:00 AM PDT Geological investigations in the Himalayas have revealed evidence that when India and Asia collided some 90 million years ago, the continental crust of the Indian tectonic plate was forced down under the Asian plate, sinking down into the Earth's mantle to a depth of at least 200 km.

Cut the salt and ditch the drugs: Controlling blood pressure in dialysis patients Posted: 29 May 2010 08:00 AM PDT For kidney patients trying to control their blood pressure, reducing fluid build-up in the blood is more effective than using antihypertensive medications, according to a new analysis. The research suggests that lowering salt intake may help reduce build-up.

Zeroing in on quantum effects: New materials yield clues about high-temperature superconductors Posted: 29 May 2010 08:00 AM PDT US and Chinese physicists are zeroing in on critical effects at the heart of the newest high-temperature superconductors, the family of iron-based compounds called "pnictides." The scientists used similarly structured materials called "oxychalcogenides" to investigate the effect of expanding the distance between iron atoms in the crystal lattice.

Empathy: College students don't have as much as they used to, study finds Posted: 29 May 2010 08:00 AM PDT Today's college students are not as empathetic as college students of the 1980s and '90s, a new study shows.

How do bumblebees get predators to buzz off? Posted: 29 May 2010 02:00 AM PDT Toxic or venomous animals, like bumblebees, are often brightly colored to tell would-be predators to keep away. However scientists in the UK have found a bumblebee's defense could extend further than its distinctive color pattern and may indeed be linked to their characteristic shape, flight pattern or buzzing sound.

Dieting alone may not help stave off type 2 diabetes; muscle mass, strength important Posted: 29 May 2010 02:00 AM PDT Sarcopenia -- low skeletal muscle mass and strength -- was associated with insulin resistance in both obese and non-obese individuals. It was also associated with high blood-sugar levels in obese people but not in thin people. These associations were stronger in people under age 60, in whom sarcopenia was associated with high levels of blood sugar in both obese and thin people, and with diabetes in obese individuals.

Experts gather as volcanic dust settles Posted: 29 May 2010 02:00 AM PDT Following the eruption of Iceland's Eyjafjallajoekull volcano that spewed huge amounts of ash and grounded numerous flights, more than 50 experts from around the world gathered at a workshop organized by ESA and EUMETSAT to discuss what has been learned and identify future opportunities for volcanic ash monitoring.

Genetic research shows degeneration in aging worm Posted: 29 May 2010 02:00 AM PDT Genetic research focusing on the soil nematode C. elegans has generated fundamental new insights into the way in which these tiny worms age. During the aging process, the activity of the worm's genes gradually becomes more turbulent and gene regulation declines. Because degenerative processes in worms and humans are similar, the research results offer clues for the prevention and medication of geriatric diseases.

Genome comparison tools found to be susceptible to slip-ups Posted: 29 May 2010 02:00 AM PDT Tools used to align genomes from different species have serious quality-control issues, according to a new study.

Many with HIV start care too late Posted: 29 May 2010 02:00 AM PDT Despite growing evidence that the earlier people are diagnosed with HIV and get access to care, the better their clinical outcomes, many HIV-infected people in the United States and Canada are not receiving the care they need early enough.

'Law-like' mathematical patterns in human preference behavior discovered Posted: 28 May 2010 05:00 PM PDT Scientists have found mathematical patterns underlying the way individuals unconsciously distribute their preferences regarding approaching or avoiding objects in their environment. These patterns appear to meet the strict criteria used to determine whether something is a scientific law and, if confirmed in future studies, could potentially be used to guide diagnosis and treatment of psychiatric disorders.

Toward a useful quantum computer: Researchers design and test microfabricated planar ion traps Posted: 28 May 2010 05:00 PM PDT Researchers are designing, fabricating and testing planar ion traps that can be more readily combined into large, interconnected trap arrays. In the future, these arrays may be used to create a useful quantum computer.

Light shed on deadly GI disease in infants born with complex congenital heart disease Posted: 28 May 2010 05:00 PM PDT Infants born with complex congenital heart disease are not only at risk for serious heart-related complications, but also for developing a deadly bowel disease, regardless of the type of surgical intervention they receive for their heart.

Novel 'cuckoo search algorithm' beats particle swarm optimization in engineering design Posted: 28 May 2010 05:00 PM PDT The familiar early summer call of the cuckoo has inspired composer and poet alike, but the sound belies the bird's true parasitic nature. Now, researchers have taken the cuckoo's wont to deposit its eggs in the nests of other birds as inspiration for a new approach to engineering design.

Planetary scientists solve 40-year-old mysteries of Mars' northern ice cap Posted: 28 May 2010 02:00 PM PDT Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars -- a chasm larger than the Grand Canyon and a series of spiral troughs -- solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars.

Modified measles virus shows potential for treating childhood brain tumors Posted: 28 May 2010 02:00 PM PDT The use of modified measles virus may represent a new treatment for a childhood brain tumor known as medulloblastoma, according to a new study.

Little-known mouth fluid may lead to test for gum disease Posted: 28 May 2010 02:00 PM PDT A little-known fluid produced in tiny amounts in the gums, those tough pink tissues that hold the teeth in place, has become a hot topic for scientists trying to develop an early, noninvasive test for gum disease, the No. 1 cause of tooth loss in adults. It's gingival crevicular fluid (GCF), produced at the rate of millionths of a quart per tooth.

Slow-release NSAIDs pose greater risk of GI bleeding, study finds Posted: 28 May 2010 02:00 PM PDT The risk of gastrointestinal complications due to non-steroidal anti-inflammatory drug (NSAID) use varies by specific NSAID administered and by dosage, according to new research. The study further determined that NSAIDs with a long half-life or slow-release formulation are associated with a greater risk of GI bleeding or perforation.

Electric supercar team aims for UK first in lead-up to world record attempt across the Americas Posted: 28 May 2010 02:00 PM PDT Students driving an electric supercar are attempting to be the first to drive an all-electric vehicle around the M25 twice on one battery charge, in the lead-up to the team's attempt to cross the Americas in July this year and break a world record.

Deep voice of alpha male: Rival's masculine voice not enough to challenge a man's dominance Posted: 28 May 2010 02:00 PM PDT Men with a deep, masculine voice are seen as more dominant by other men but a man's own dominance - perceived or actual - does not affect how attentive he is to his rivals' voices. His own dominance does however influence how he rates his competitors' dominance: the more dominant he thinks he is, the less dominant he rates his rival's voice, according to new research.

If you don't brush your teeth twice a day, you're more likely to develop heart disease, study finds Posted: 28 May 2010 11:00 AM PDT Individuals who have poor oral hygiene have an increased risk of heart disease compared to those who brush their teeth twice a day, finds new research.
