PHILADELPHIA — For tens of thousands of years, the genomes of malaria parasites and humans have been at war with one another. Now, University of Pennsylvania geneticists, in collaboration with an international team of scientists, have developed a new picture of one way that the human genome has fought back. The international team was led by Sarah Tishkoff, a Penn Integrates Knowledge professor with appointments in the genetics department in Penn's Perelman School of Medicine and the biology department of biology in the School of Arts and Sciences, and Wen-Ya Ko, a postdoctoral ...

(Garrison, NY) Should physicians be banned from assisting in a lethal injection execution, or lose professional certification for doing so? A recent ruling by the American Board of Anesthesiology will revoke certification of anesthesiologists who participate in capital punishment, and other medical boards may act similarly. An article in the Hastings Center Report concludes that decertification of physicians participating in lethal injections by a professional certifying organization goes too far—though individual physicians and private medical groups like the AMA are ...

After eight years of work, researchers have unearthed what has been a well-kept secret of our immune system's success. The findings published online on June 9th in Immunity, a Cell Press publication, offer an explanation for how specialized immune cells are able to kill infected or cancerous cells without killing themselves in the process. The focus of the study is a molecule known as perforin, whose job it is to open up a pore in cells targeted for destruction. With that pore in place, proteases known as granzymes can enter target cells and destroy them. Perforin ...

PROVIDENCE, R.I. [Brown University] — Given how much patients invest in in vitro fertilization (IVF), both financially and emotionally, tools to inform couples about what they might expect during their treatment can be welcome. A study by researchers at Brown University and Women & Infants Hospital shows that as the IVF cycle is beginning, a blood test for levels of a hormone called AMH, or antimullerian hormone, can help predict the number of eggs that will be harvested. "Clinicians can measure AMH before or during ovarian stimulation to counsel couples about their likelihood ...

EAST LANSING, Mich. — It's time for the United States to consider establishing higher standards for math teachers if the nation is going to break its "vicious cycle" of mediocrity, a Michigan State University education scholar argues in Science magazine. As American students continue to be outpaced in mathematics by pupils in countries such as Russia and Taiwan, William Schmidt recommends adopting more rigorous, demanding and internationally benchmarked teacher-preparation standards for math teachers. "Our research shows that current teacher-preparation programs for ...

A new study uncovers a brain mechanism that could be targeted for new medications designed to help people quit smoking without gaining weight. This research, funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, shows that a specific subclass of brain nicotinic receptor is involved in nicotine's ability to reduce food intake in rodents. Prior research shows that the average weight gain after smoking is less than 10 pounds, but fear of weight gain can discourage some people who would like to quit. In the study, to be published ...

On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms. "A photon, the unit of light, is just energy, which, when captured by the pigment rhodopsin, most of the time causes ...

COLUMBUS, Ohio – A Detroit entrepreneur surprised university engineers here recently, when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record – in less than 10 seconds. In fact, the steel, now trademarked as Flash Bainite, has tested stronger and more shock-absorbing than the most common titanium alloys used by industry. Now the entrepreneur is working with researchers at Ohio State University to better understand the science behind the new treatment, called flash processing. What they've discovered may hold the key to making ...

WEST LAFAYETTE, Ind. - Researchers have developed a new type of imaging technology to diagnose cardiovascular disease and other disorders by measuring ultrasound signals from molecules exposed to a fast-pulsing laser. The new method could be used to take precise three-dimensional images of plaques lining arteries, said Ji-Xin Cheng, an associate professor of biomedical engineering and chemistry at Purdue University. Other imaging methods that provide molecular information are unable to penetrate tissue deep enough to reveal the three-dimensional structure of the plaques, ...

Strong thunderstorms are the life's blood of tropical cyclones, and infrared and radar satellite data from NASA today confirms that the eastern Pacific Ocean's first hurricane has plenty of them and they're over 9 miles high. Adrian exploded in growth overnight from a tropical storm on June 8 to a major hurricane today. NASA's Aqua satellite flew over Hurricane Adrian this morning at 8:29 UTC (1:59 a.m. EDT), and the Atmospheric Infrared Sounder instrument took an infrared snapshot of the storm's many strong thunderstorms and warm ocean water below. The infrared data ...

New research shows how the protein missing in fragile X syndrome – the most common inherited form of intellectual disability – acts as a molecular toggle switch in brain cells. The fragile X protein, called FMRP, hooks up with a group of molecules called microRNAs to switch the production of other proteins on and off in response to chemical signals, scientists at Emory University School of Medicine have discovered. The results appear in the June 10 issue of Molecular Cell. "For learning and memory to take place, neurons need to be able to make new proteins on demand, ...

GOES-13 satellite imagery on June 9 shows that the pesky low pressure area in the north Caribbean Sea is stretching out and bringing soaking rains to Cuba, Hispaniola, Jamaica and Puerto Rico. The Geostationary Operational Environmental Satellite called GOES-13 captured an image of this low on June 9 at 1740 UTC (1:40 p.m. EDT) System 94L, and the cloud cover appears centered over eastern Cuba and Jamaica while the outer portion of the low stretches over Hispaniola, Puerto Rico and now south Florida. The elongated low has a minimum central pressure of 1001 millibars and ...

In April 2007, teacher Irka Elsevier and then-graduate student Biance Moebius-Clune began their second inquiry unit designed to enable high school students to better understand soil science concepts through their own research and experiments. Moebius-Clune was an NSF fellow in the Cornell Science Inquiry Partnerships (CSIP) program, which allowed the pair to develop inquiry curriculum to guide students through the process of doing research themselves. Soil is fundamental to life and relevant to some of today's most pressing global issues, such as climate change and demand ...

NASA's Aqua satellite and the GOES-13 satellite both captured their own unique views of the eruption of the Puyehue-Cordón Caulle volcano in Chile this week. One satellite provided a high-resolution image of the ash plume while the other provided a video showing the plumes movement over several days. NASA's GOES Project released a satellite animation of the Puyehue-Cordón Caulle volcano that shows the movement of the ash plume over several days. The NASA GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md. created the animation from images obtained ...

Some asteroids may have been like "molecular factories" cranking out life's ingredients and shipping them to Earth via meteorite impacts, according to scientists who've made discoveries of molecules essential for life in material from certain kinds of asteroids and comets. Now it appears that at least one may have been less like a rigid assembly line and more like a flexible diner that doesn't mind making changes to the menu. In January, 2000, a large meteoroid exploded in the atmosphere over northern British Columbia, Canada, and rained fragments across the frozen surface ...

AMARILLO – A two-year study by a Texas AgriLife Research team in Amarillo has helped bring a new product to market that could allow the cattle feeding industry to realize efficiencies in mills and more weight on cattle, according to Dr. Jim MacDonald. MacDonald, an AgriLife Research beef cattle nutritionist, finished his second trial of cattle early this year studying starter diets in feedlots during the transition phase from pasture to feed yard. Typically, a steer or heifer will come off of a forage diet when it goes into the feedlot, he explained. For the first ...
