The U-led study is the first attempt to map escape routes for wildland fire fighters from an aerial perspective. The researchers used LiDAR technology to analyze the terrain slope, ground surface roughness and vegetation density of a fire-prone region in central Utah, and assessed how each landscape condition impeded a person’s ability to travel.
A new report shows how microsystems can be used to understand processes in heart tissue in detail and to test newly developed compounds applied in the treatment of cardiac diseases.
Liraglutide injection, a prescription medication used to treat type-2 diabetes and obesity is associated with marked slowing of stomach emptying and is an effective weight loss therapy. These are the findings of a randomized, double-blind, placebo-controlled study by Mayo Clinic researchers published today in The Lancet Gastroenterology & Hepatology.
Use of activity trackers, such as wearable devices and smartphone apps, is on the rise, and a new study shows that 80 percent of users stuck with the device for at least six months. Though the gadgets may help motivate users to increase exercise, the populations that could benefit most may not be using the technologies. In the first national study of a large, diverse population, researchers at the Perelman School of Medicine at the University of Pennsylvania and colleagues, found that 1.2 percent of the study population engaged with devices, and that most of the individuals who started using an activity tracker were younger and had higher-incomes than people who opted not to use the devices.
Two drugs, already approved for safe use in people, may be able to improve therapy for chronic myeloid leukemia (CML), a blood cancer that affects myeloid cells, according to results from a University of Iowa study in mice.
Using X-ray techniques, scientists are developing an analysis tool that can more accurately predict how sulfur compounds in a batch of crude oil might corrode equipment– an important safety issue for the oil industry.
Pediatric researchers in the Roberts Collaborative for Genetics and Individualized Medicine at Children's Hospital of Philadelphia have identified common gene variants that raise the risk of developing an aggressive form of the childhood cancer neuroblastoma. The discovery, in the MMP20 gene, may assist doctors in better diagnosing subtypes of neuroblastoma.
Do you really need that MRI? Your doctor may order an MRI based on factors other than your actual medical need for imaging, researchers in UT Southwestern’s Center for Patient-Centered Outcomes Research found. Their study in JAMA Internal Medicine showed that a physician’s prior image-ordering habits, as well as ownership of the equipment, were strong indicators of unnecessary imaging orders.
People taking a new oral medication for Type 2 diabetes can breathe a sigh of relief concerning suspicions they might be at an increased risk for many types of cancer, according to Indiana University researchers.
Scientists have nailed the biomechanics of a centuries-long puzzle on how freshwater flatworms reproduce. Asexual flatworms called planarians tear themselves into two pieces that go on to form two new worms. Researchers are now able to predict where planarian fission occurs based on its anatomy.
Mayo Clinic scientists have shown that injections of a hunger hormone blocker in mice can halt the typical weight gain after dieting and help prevent rebound obesity in the long term.
A University of Wisconsin–Madison physicist and his colleagues are turning IceCube, the world’s most sensitive neutrino telescope, to the task of helping demystify powerful pulses of radio energy generated up to billions of light-years from Earth.
Heart function improved by up to 25 percent in a trial using gene therapy to reverse cardiac damage from congestive heart failure in a large animal model, Mount Sinai researchers report. This is the first study using a novel vector for gene therapy to improve heart function in non-ischemic heart failure.
Researchers at Osaka University in Japan are working to exploit stochastic resonance to enhance signal transmission for a new generation of devices, using single-walled carbon nanotubes. They created a summing network SR device that detects subthreshold signals, fabricated to include a self-noise component. The researchers report their findings this week in the journal Applied Physics Letters.
A Texas A&M University research team has examined a 100,000-year-old ocean core and found that there have been at least eight occurrences of iron penetrating the Pacific Ocean, each likely associated with abrupt global climate change over thousands of years.
A study to be published in the September 29 issue of the Journal of Biological Chemistry reports the use of an emerging method to identify proteins that allows two organelles, the mitochondria and the endoplasmic reticulum, to attach to each other.
A University of Washington-led study of college students has found that the social dynamics of a group, such as whether one person dominates the conversation or whether students work with a friend, affect academic performance. Put simply, the more comfortable students are, the better they do, which yields benefits beyond the classroom.
Satellite data shows underground water reserves in California’s Silicon Valley rebounded quickly after the recent severe drought. The research points to the success of aggressive conservation measures and lays the groundwork for low-cost monitoring of subterranean water reserves around the world.
A new type of “bijel” created by Berkeley Lab scientists could one day lead to applications in soft robotics, liquid circuitry, and energy conversion.
Largest study to date identifies gender-specific patterns of autism and related disorders occurrence among sibling pairs.
