RIVERSIDE, Calif. — A research team led by biogeochemists at the University of California, Riverside has filled in a billion-year gap in our understanding of conditions in the early ocean during a critical time in the history of life on Earth. It is now well accepted that appreciable oxygen first accumulated in the atmosphere about 2.4 to 2.3 billion years ago. It is equally well accepted that the build-up of oxygen in the ocean may have lagged the atmospheric increase by well over a billion years, but the details of those conditions have long been elusive because of ...

WASHINGTON -- A new National Research Council report finds that by the year 2050, the U.S. may be able to reduce petroleum consumption and greenhouse gas emissions by 80 percent for light-duty vehicles -- cars and small trucks -- via a combination of more efficient vehicles; the use of alternative fuels like biofuels, electricity, and hydrogen; and strong government policies to overcome high costs and influence consumer choices. While achieving these goals will be difficult, improving technologies driven by strong and effective policies could make deep reductions possible. "To ...

People suffering from complicated grief may have difficulty recalling specific events from their past or imagining specific events in the future, but not when those events involve the partner they lost, according to a new study published in Clinical Psychological Science, a journal of the Association for Psychological Science. The death of a loved one is among the most painful and disruptive experiences a person can face. For most, the grief subsides over time. But those who suffer from complicated grief continue to yearn for the lost loved one, experience waves of painful ...

CHAMPAIGN, Ill. — New research suggests that elite athletes – Olympic medalists in volleyball, for example – perform better than the rest of us in yet another way. These athletes excel not only in their sport of choice but also in how fast their brains take in and respond to new information – cognitive abilities that are important on and off the court. The study, of 87 top-ranked Brazilian volleyball players (some of them medalists in the Beijing and London Olympics) and 67 of their nonathletic contemporaries, also found that being an athlete minimizes the performance ...

A team of five Las Cumbres engineers, technicians, and a postdoc, convened at Sutherland for three weeks during late February and early March to achieve this feat. "The South African Astronomical Observatory is pleased to collaborate with the Las Cumbres Observatory Global Telescope project, and ...

Some diseases are caused by single gene mutations. Current techniques for identifying the disease-causing gene in a patient produce hundreds of potential gene candidates, making it difficult for scientists to pinpoint the single causative gene. Now, a team of researchers led by Rockefeller University scientists have created a map of gene "shortcuts" to simplify the hunt for disease-causing genes. The investigation, spearheaded by Yuval Itan, a postdoctoral fellow in the St. Giles Laboratory of Human Genetics of Infectious Diseases, has led to the creation of what he calls ...

Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition. The finding, published in Proceedings of the National Academy of Sciences, profiles the SR1 bacteria, a group of microbes present in many environments, ranging from the mouth to deep within the Earth, that have never been cultivated in the laboratory. Human oral SR1 bacteria are elevated in periodontitis, a disease marked by inflammation and infection of the ligaments and bones ...

PROVIDENCE, R.I. [Brown University] — Large chunks of an ancient tectonic plate that slid under North America millions of years ago are still present under parts of central California and Mexico, according to new research led by Brown University geophysicists. Around 100 million years ago, the Farallon oceanic plate lay between the converging Pacific and North American plates, which eventually came together to form the San Andreas fault. As those plates converged, much of the Farallon was subducted underneath North America and eventually sank deep into the mantle. Off ...

Infrared satellite imagery tells the temperature of the cloud tops within a tropical cyclone as well as the sea surface temperatures around the storms. A recent infrared image from NASA's Aqua satellite showed very little strength in the remnants of ex-cyclone Tim offshore from southeastern Queensland. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured an infrared image of Cyclone Tim on March 18 at 0355 UTC (March 17 at 11:55 p.m. EDT). The AIRS image showed that cloud top temperatures had warmed significantly since the previous ...

A study in the JAMA Neurology (formerly the Archives of Neurology) suggests that controlling or preventing risk factors such as hypertension earlier in life may limit or delay the brain changes associated with Alzheimer's disease and other age-related neurological deterioration. Dr. Karen Rodrigue, assistant professor in the UT Dallas Center for Vital Longevity (CVL), was lead author on a study that looked at whether people with both hypertension and a common gene associated with risk of Alzheimer's disease (the APOE-4 gene carried by about 20 percent of the population) ...

Stingrays living in one of the world's most famous and heavily visited ecotourism sites — Stingray City/Sandbar in the Cayman Islands — have profoundly changed their ways, raising questions about the impact of so-called "interactive ecotourism" on marine wildlife, reports a new study published March 18 in the journal PLOS ONE. Researchers from Nova Southeastern University's Guy Harvey Research Institute in Hollywood, Fla., and the University of Rhode Island studied the southern stingray population of Stingray City — a sandbar in the Cayman Islands that draws nearly a ...

Lowering the costs of healthy foods in supermarkets increases the amount of fruits, vegetables and whole grain foods that people eat, while also appearing to reduce consumption of nutritionally less-desirable foods, according to research from the RAND Corporation. Researchers examined a program available to members of South Africa's largest private health insurance company that provides a rebate of 10 percent or 25 percent on purchases of healthy foods. The program, started in 2009, now has about 800 participating supermarkets and enrolls more than 260,000 households. ...

CHICAGO — Many of today's running shoes feature a heavy cushioned heel. New research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that these shoes may alter an adolescent runner's biomechanics (the forces exerted by muscles and gravity on the skeletal structure) and diminish performance. Researchers recruited 12 adolescent competitive athletes from local track teams, and asked them to run on a treadmill in large heel trainers, track flats and without any shoes (barefoot) at four different speeds. Biomechanics ...

CHICAGO — Osteoarthritis of the hip or knee, affecting millions of Americans each year, is known to limit sexual activity. New research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that total hip (THR) or total knee replacement (TKR) surgery improves sexual function in 90 percent of patients. In the study, 147 patients under age 70, scheduled for primary THR or TKR, agreed to participate in a study requiring the completion of questionnaires prior to surgery, at six months post surgery, and at one year post surgery. ...

CHICAGO — New research presented today at the at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that overall, sports and recreation musculoskeletal injuries have declined 12.4 percent in the U.S. over the past 10 years for children ages 5 to 14 years. However, injuries sustained during football and soccer continues to rise. In 2000, the U.S. Centers for Disease Control (CDC) reported the top eight sports and recreational activities responsible for injuries in children ages 5 to 14, and estimated their annual cost at more than $33 ...

CHICAGO – Magnetic Resonance Imaging (MRI) can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Early detection can result in timely revision surgery, decreasing the risk for further tissue damage and pain. Researchers reviewed the MRI images of 70 patients who ultimately underwent revision surgery for a failed MoM implant. The images were assessed for the presence of tissue damage, swelling and other characteristics. ...

CHICAGO – High-energy lower-extremity trauma (HELET) is common in modern warfare, often resulting in severe tissue damage, chronic pain, neurovascular injury and significant muscle loss, according to the new research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). The Return to Run (RTR) program is an integrated orthotic and rehabilitation initiative designed to return high-level function to wounded warriors.

CHICAGO – Smoking is a known risk factor for back pain and disc disease. In a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers reviewed smoking cessation rates and related pain in 6,779 patients undergoing treatment for spinal disorders with severe axial (spine) or radicular (leg) pain. Information on each patient's age, gender, weight, smoking history, assessment of pain, treatment type and co-morbid depression also were assessed. Overall, 8.9 percent of patients over the age of 55 smoked compared ...

CHICAGO – While it is well known that a majority of hip fracture patients of all ages and both sexes have insufficient or deficient levels of vitamin D, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) looks at whether or not living in a warm, sunny climate improves patient vitamin D levels. Researchers retrospectively reviewed the vitamin D levels of 1,539 patients, including 448 acute hip fracture patients and 1,091 total hip (THR) or total knee replacement (TKR) patients, from December 2010 to December 2011 ...
