New skeletons from the age of dinosaurs answer century-old questions about prehistoric reptile Typothorax Posted: 31 May 2010 08:00 AM PDT More than 100 years ago, paleontologist E. D. Cope of "Dinosaur Wars" fame found a few fragmentary bones of a reptile in the deserts of New Mexico. He named the reptile Typothorax. A century later, Typothorax -- which belongs to a group of reptiles called aetosaurs -- remained something of a mystery, known mainly from pieces of armor, a few limb bones, and some sections of tail. Now, thanks to two remarkably complete skeletons, paleontologists are finally revealing what Typothorax really looked like.

Natural self-repair mechanisms that kick in after spinal cord injury identified Posted: 31 May 2010 08:00 AM PDT University of Alberta researchers have identified one of the body's natural self-repair mechanisms that kick in after spinal cord injury which could lead to the development of more effective treatments.

Air traffic poised to become a major factor in global warming, scientists predict Posted: 31 May 2010 08:00 AM PDT The first new projections of future aircraft emissions in 10 years predict that carbon dioxide and other gases from air traffic will become a significant source of global warming as they double or triple by 2050.

Surgery outperforms drug therapy in treatment of benign prostatic hyperplasia, research finds Posted: 31 May 2010 08:00 AM PDT A 17-year-long community study looking at symptoms of enlarged prostate in over 2,000 men age 40 to 79 years suggests that surgery for benign prostatic hyperplasia offers more relief from incontinence and obstruction symptoms than treatment from drug-based therapy, according to a new study.

Reforestation may lower the climate change mitigation potential of forests Posted: 31 May 2010 08:00 AM PDT Scientists in the U.S. and China have found that reforestation and afforestation -- the creation of new forests -- may lower the potential of forests for climate change lessening.

Genetic makeup of Hispanic/Latino Americans influenced by Native American, European and African-American ancestries Posted: 31 May 2010 08:00 AM PDT A new study finds that the imprint of European colonialism and imperialism is evident in the genetic makeup of today's Hispanic/Latino American populations. Scientists discovered that Europeans, Native Americans, as well as West Africans brought to the US and Latin America by the trans-Atlantic slave trade, have influenced the genes of the current Hispanic/Latino populations. However, a large variation in genes among individuals within each population were still found to exist.

Acupuncture's molecular effects pinned down: New insights spur effort to boost treatment's impact significantly Posted: 31 May 2010 05:00 AM PDT Scientists have identified the molecule adenosine as a central player in parlaying some of the effects of acupuncture in the body.

NOAA predicts below normal Eastern Pacific hurricane season Posted: 31 May 2010 02:00 AM PDT NOAA's National Weather Service Climate Prediction Center has announced that projected climate conditions point to a below normal hurricane season in the Eastern Pacific this year. The outlook calls for a 75 percent probability of a below normal season, a 20 percent probability of a near normal season and a five percent probability of an above normal season.

New technology will make election voting more efficient Posted: 31 May 2010 02:00 AM PDT Did you stay up all night to hear your local result during the recent election? Time-consuming manual vote-counts and ballot boxes could soon be consigned to the history books, thanks to innovative new secure voting technology.

How whales have changed over 35 million years Posted: 30 May 2010 11:00 PM PDT Evolutionary biologists have looked back 35 million years to provide the first test of why whales show such rich diversity. Species diversification and body size of whales were established early in their evolution.

Genes associated with throat cancer found through study of over 10,000 subjects Posted: 30 May 2010 11:00 PM PDT Scientists from Singapore, China and USA have identified three new susceptibility genes in a genome-wide association study of nasopharyngeal carcinoma (NPC). The study advances understanding of the important role of host genetic variation in influencing susceptibility to NPC.

Spawning habitat of bluefin tuna in Gulf of Mexico: Critical area intersects Deepwater Horizon oil spill Posted: 30 May 2010 11:00 PM PDT Electronic tagging and fisheries catch data have revealed pronounced differences in preferred habitat of Atlantic bluefin tuna and yellowfin tuna in the Gulf of Mexico, despite their close ancestry, according to a new study. Bluefin tuna return to the same regions of the Gulf of Mexico during spring months to spawn. Yellowfin tuna are more widely distributed throughout the warm Gulf waters and occupy the region throughout the year.

Comparison of overall survival for non-small cell lung cancer patients Posted: 30 May 2010 11:00 PM PDT Patients with early stages of NSCLC are typically treated with surgery, but those with stage IIIA present more of a challenge because they are such a diverse group. However, new research shows that patient's with stage IIIA NSCLC who receive surgery, lobectomy in particular, have increased overall survival compared to those who received chemoradiation alone -- those receiving lobectomy plus chemoradation had survival rates that were higher than previously reported as well.

NOAA expands fishing closed area in Gulf of Mexico; approximately 75 percent of Gulf still open for fishing Posted: 30 May 2010 11:00 PM PDT NOAA has extended the closed fishing area in the Gulf of Mexico to include a large area of oil sheen patches crossing the eastern edge of the current boundary, as well as an area currently outside the southern boundary which a small portion of the sheen is moving toward.

Consent forms for research: Have they improved in 25 years? Posted: 30 May 2010 11:00 PM PDT Consent forms that people sign before participating in research are widely considered difficult to understand and sometimes inaccurate. Lack of clarity was implicated in a high-profile legal settlement in April between Arizona State University and a Native American tribe, which claimed that blood samples that its members provided for genetic research were used for purposes not stated in the consent form. Efforts have been made to improve the forms, but how effective are they?

Clocks in the Americas and the Caribbean Islands now ticking in unison Posted: 30 May 2010 02:00 PM PDT Clocks in the Americas and the Caribbean Islands are now ticking in unison thanks to the work of the Sistema Interamericano de Metrologia (SIM), a regional metrology organization that works to promote accurate measurements throughout the Americas.

Consumers: Why do you like what I like, but I don't like what you like? Posted: 30 May 2010 02:00 PM PDT When we like a product, do we think others will like it, too? And when we believe others like a product, do we like it as well? A new study says these two questions are fundamentally different.

Coastal birds carry toxic ocean metals inland Posted: 30 May 2010 08:00 AM PDT Biologists has found that potent metals like mercury and lead, ingested by Arctic seabirds feeding in the ocean, end up in the sediment of polar ponds.

Those with allergic asthma face double trouble during flu season, findings suggest Posted: 30 May 2010 08:00 AM PDT New research suggests that allergic reactions to pet dander, dust mites and mold may prevent people with allergic asthma from generating a healthy immune response to respiratory viruses such as influenza.

New explaination of how certain cancers develop Posted: 30 May 2010 08:00 AM PDT Researchers have discovered a new interaction between a cell signaling system and a specific gene that may be the cause of B-cell lymphoma. The finding suggests a similar interaction could be occurring during the development of other types of cancer, leading to further understanding of how cancer works -- and how it might be stopped.

How RNA viruses copy themselves: Hijack cellular enzyme to create viral replication factories on cell membranes Posted: 30 May 2010 08:00 AM PDT Researchers have made a significant new discovery about RNA (ribonucleic acid) viruses and how they replicate themselves. Certain RNA viruses -- poliovirus, hepatitis C virus and coxsackievirus -- and possibly many other families of viruses copy themselves by seizing an enzyme from their host cell to create replication factories enriched in a specific lipid. The scientists have uncovered that certain RNA viruses take control of a cellular enzyme to design a replication compartment on the cell's membrane filled with PI4P lipids. Those lipids, in turn, allow the RNA viruses to attract and stimulate the enzymes they need for replication.

Underwater robot sent to study Deepwater Horizon spill Posted: 30 May 2010 08:00 AM PDT A high-tech robotic submersible has been sent to the oily waters of the Gulf of Mexico. The goal is to collect information about the oil plume from the Deepwater Horizon drilling rig accident for the National Oceanic and Atmospheric Administration.

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.
