Scientists are getting closer to tracing the sources of meteorites that fall to Earth.
Simulations predict that behavioral interventions such as imposing strict no-food restrictions after meals can be as effective as strong anorectic drugs in reducing food intake in rodents, according to a study.
Rats exchange information about danger in a reciprocal fashion, and this information transfer is at least partially mediated by a brain region called the anterior cingulate cortex.
Organizations aren't moving quickly enough on cyber security threats linked to the drive toward using personal mobile devices in the workplace.
A newly engineered peptide called IBP-CP24 has the potential to be further developed as a long-acting anti-HIV drug that can be used alone or in combination with a broad neutralizing antibody for the treatment and prevention of HIV-1 infection, according to a new study.
Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn't all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of the skulls of 160 non-avian dinosaurs revealed the evolution of common traits in the skulls and teeth of plant-eating members of otherwise very...
Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body.
A fundamental change in our understanding of the childhood kidney cancer Wilms' tumor is on the horizon, after the discovery of its earliest genetic root by scientists. By comparing genome sequences from normal kidney tissue and tumors, the team identified patches of normal-looking kidney tissue that in fact carried DNA changes that cause Wilms' tumor.
Tropical species are six times more sensitive to forests being broken up for logging or farming than temperate species, says new research.
Researchers have found that a 10-hour time-restricted eating intervention, when combined with traditional medications, resulted in weight loss, reduced abdominal fat, lower blood pressure and cholesterol for participants. The pilot study could lead to a new treatment option for metabolic syndrome patients who are at risk for developing life-altering and costly medical conditions such as diabetes.
Researchers report the discovery of three cell types in the eye that detect light and align the brain's circadian rhythm to our ambient light. The study marks the first direct assessment in humans of light responses from these cells, called intrinsically photosensitive retinal ganglion cells (ipRGCs) -- and the implications for health are substantial.
Scientists are recommending early diagnosis, prevention and treatment of severe chronic inflammation to reduce the risk of chronic disease and death worldwide.
sci-Plex, a new cell-response screening method, pools genetically different cells and shows what happens to individual cells when the sample is treated, such as with cancer drugs. The technology collects information on changes in genetic expression in each labeled cell, providing data useful in exploring mechanisms triggered by drugs or other agents.
Researchers have cleared a major obstacle in the development of an HIV vaccine, proving in animal models that effective, yet short-lasting antibodies can be coaxed into multiplying as a fighting force against the virus.
Bats face many threats -- from habitat loss and climate change to emerging diseases, such as white-nose syndrome. But it appears that wildfire is not among those threats.
Tropical species are six times more sensitive to forests being broken up for logging or farming than temperate species, says new research.
A joint research team led by Mao Fangyuan from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and Meng Jin from the American Museum of Natural History reported a new symmetrodont, Origolestes lii, a stem therian mammal from the Early Cretaceous Jehol Biota, in China's Liaoning Province.

SpaceX launched a 3-ton shipment to the International Space Station on Thursday, including "mighty mice" for a muscle study, a robot sensitive to astronauts' emotions and a miniature version of a brewery's malt house.
A fresh SpaceX Falcon 9 rocket launched a recycled robotic Dragon cargo capsule today, carrying 5,700 pounds of supplies, satellites and science to the International Space Station. In contrast with Wednesday's planned launch attempt, which was called off due to excessively high upper-level winds, today's countdown proceeded smoothly to liftoff at 12:29 p.m. ET (9:29 a.m. PT) from Cape...
A random conversation between two Cornell researchers at a child's birthday party led to a collaboration and new understanding of how bacteria resist toxins, which may lead to new tools in the fight against harmful infections.
Caldera-forming eruptions are among Earth’s most hazardous natural phenomena, yet the architecture of subcaldera magma reservoirs and the conditions that trigger collapse are poorly understood. Observations from the formation of a 0.8–cubic kilometer basaltic caldera at Kīlauea Volcano in 2018 included the draining of an active lava lake, which provided a window into pressure...
Changes in magma chemistry that affect eruptive behavior occur during many volcanic eruptions, but typical analytical techniques are too slow to contribute to hazard monitoring. We used rapid energy-dispersive x-ray fluorescence analysis to measure diagnostic elements in lava samples within a few hours of collection during the 2018 Kīlauea eruption. The geochemical data provided important...
