The first mission involving the autonomous submarine vehicle Autosub Long Range (better known as 'Boaty McBoatface') has for the first time shed light on a key process linking increasing Antarctic winds to rising sea temperatures. Data collected from the expedition will help climate scientists build more accurate predictions of the effects of climate change on rising sea levels.
Modern hyenas are known as hunters and scavengers in Asian and African ecosystems such as the savanna. But in ancient times, these powerful carnivores also roamed a very different landscape, inhabiting the frigid Arctic during the last ice age. A new study reports on the first hyena fossils discovered in the Arctic -- two teeth.
Scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils. They didn't find the protein, but they did find huge colonies of modern bacteria living inside the dinosaur bones.
Adolescents with autism need the support of their parents or guardians to prioritize independence so that they are prepared for learning to drive, according to a study of specialized driving instructors who have worked specifically with young autistic drivers.
New research offers insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. The findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for developing future weight-loss treatments, they said.
Using a rat model for high blood pressure (hypertension), a common chronic cardiovascular condition, researchers found that preexisting hypertension altered normal reflexes in the lungs to affect autonomic regulation of the heart when an irritant mimicking air pollution was inhaled.
Newly developed geological techniques help uncover the most accurate and high-resolution climate records to date, according to a new study. The research finds that the standard practice of using modern and fossil coral to measure sea-surface temperatures may not be as straightforward as originally thought. By combining high-resolution microscopic techniques and geochemical modeling, researchers are using the formational history of Porites coral skeletons to fine-tune the records used to make global climate predictions.
Ecologists have long relied on their senses when it comes to recording animal populations and species diversity. However, modern programmable sound recording devices are now the better option for logging animal vocalizations. Scientists have investigated this using studies of birds as an example.
Administering anti-inflammatory treatments that prevent inflammation as well as proresolution treatments that tamp down the body's inflammatory response to surgery or chemotherapy can promote long-term survival in experimental animal cancer models, new research shows.
A new study shows that over the past 10,000 years, humanity has experienced a number of foundational transitions, or 'bottlenecks.' During these periods of transition, the advance or decline of societies was related to energy availability in the form of a benign climate and other factors.
Leptin, a hormone secreted by fat cells, informs the brain about sufficiency of fuel stores. When insufficient, leptin levels fall, triggering increases in appetite. A study by researchers from Yale University School of Medicine and Harvard Medical School has demonstrated a mechanism by which low leptin stimulates food intake in rodents. Leptin informs the brain [...]
Feet from the raw bars and sherbet-colored condominiums of Florida's Cedar Key, researchers discovered a new species of egg-sucking sea slug, a rare outlier in a group famous for being ultra-vegetarians.
