UCLA has performed its first transcatheter aortic valve replacement (TAVR), using a new device approved by the U.S. Food and Drug Administration to replace an aortic valve in a patient who was not a candidate for open-heart surgery. The procedure took place on Aug. 9.

Ronald Reagan UCLA Medical Center is part of a growing trend of hospitals nationwide offering this new minimally invasive procedure. (more…)

Synopsis

Will Montgomery is a master thief who after being double-crossed in a heist gone awry is sent to prison for 8 years. Upon his release he’s ready to leave his criminal past behind and try to rebuild a relationship with his estranged daughter Allison. The FBI and his old cohorts believe that he hid the loot from the last heist eight years ago, $10 million in bonds. To get his hands on it, his old partner Vincent kidnaps Allison and demands the entire $10 million as ransom. Keeping her in the soundproofed trunk of a taxi cab, he’s able to stay mobile amongst the throngs of taxis out during Mardi Gras, making it nearly impossible to find. Montgomery only has one day to get the $10 million ransom, but much to the disbelief of the FBI on his trail and Vincent, Will doesn’t actually have it. Instead, he must trust his instincts and his old partner in crime, the beautiful, sexy and smart Riley, to do one more clever heist to get his daughter back alive before it’s too late. (more…)

USGS Releases U.S. Oil & Gas Reserve Growth Estimates

WASHINGTON – The U.S. Geological Survey (USGS) has released a new estimate for potential additions to domestic oil and gas reserves from reserve growth in discovered, conventional accumulations in the United States. The USGS estimates that the mean potential undiscovered, conventional reserve additions for the United States total 32 billion barrels (bb) of oil, 291 trillion cubic feet (tcf) of natural gas, and 10 bb of natural gas liquids, constituting about 10 percent of the overall U.S. oil and gas endowment.

“As part of the Obama Administration’s all-of-the-above energy strategy, we are taking aggressive steps to safely and responsibly expand domestic energy production,” said Interior Secretary Ken Salazar. “USGS’s ongoing work to identify and estimate U.S. energy supplies – and to make that information available to everyone – is fundamental to our efforts to continue to grow America’s energy economy.” (more…)

Common Parasite May Trigger Suicide Attempts

EAST LANSING, Mich. — A parasite thought to be harmless and found in many people may actually be causing subtle changes in the brain, leading to suicide attempts.

New research appearing in the August issue of The Journal of Clinical Psychiatry adds to the growing work linking an infection caused by the Toxoplasma gondii parasite to suicide attempts. Michigan State University’s Lena Brundin was one of the lead researchers on the team.

About 10-20 percent of people in the United States have Toxoplasma gondii, or T. gondii, in their bodies, but in most it was thought to lie dormant, said Brundin, an associate professor of experimental psychiatry in MSU’s College of Human Medicine. In fact, it appears the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. (more…)

UF Scientists Find State Record 87 Eggs In Largest Python From Everglades

GAINESVILLE, Fla. — University of Florida researchers curating a 17-foot-7-inch Burmese python, the largest found in Florida, discovered 87 eggs in the snake, also a state record.

Scientists at the Florida Museum of Natural History on the UF campus examined the internal anatomy of the 164.5-pound snake Friday. The animal was brought to the Florida Museum from Everglades National Park as part of a long-term project with the U.S. Department of the Interior to research methods for managing the state’s invasive Burmese python problem. Following scientific investigation, the snake will be mounted for exhibition at the museum for about five years, and then returned for exhibition at Everglades National Park. (more…)

Berkeley Lab and UC Berkeley Researchers Record First Direct Observations of Quantum Effects in an Optomechanical System

A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects – recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into the Death Star. While tractor beams of this sort remain science fiction, beams of light today are being used to mechanically manipulate atoms or tiny glass beads, with rapid progress being made to control increasingly larger objects. Those who see major roles for optomechanical systems in a host of future technologies will take heart in the latest results from a first-of-its-kind experiment. (more…)

UCLA School of Nursing study shows walnuts improve sperm quality

Eating about two handfuls of walnuts a day may provide men the added boost they need to improve their fertility, according to a breakthrough study by researchers at the UCLA School of Nursing.

Findings from the study, “Walnuts Improve Semen Quality in Men Consuming a Western-Style Diet: Randomized Control Dietary Intervention Trial,” are published Aug. 15 in the “papers in press” section of the peer-reviewed journal Biology of Reproduction.

This is the first study to look at the effects of a plant source of omega-3 on sperm, the researchers say. Statistics from the American Society for Reproductive Medicine show that one in six couples is infertile, with about 40 percent of these cases due to a male factor. (more…)

MU Researchers Work to Further Biofuel Production without Increasing Food Prices

COLUMBIA, Mo. – America is looking for more biofuel through the use of crops such as corn and soybeans, but concerns about higher food prices persist when land for biofuel displaces land for food crops. Now, researchers at the University of Missouri are hoping to increase biofuel production without impacting food production. This fall, MU scientists are beginning a study to determine how non-food biofuel crops, such as switchgrass, grow in marginal land along the floodplains, where most crops cannot thrive. (more…)
