A prehistoric monster worm that terrorized the Devonian seas some 400 million years ago has been identified by an international team of paleontologists from the University of Bristol, Lund University and the Royal Ontario Museum. The team, led by Lund University Professor Mats Eriksson, studied an ancient fossil, which has been stored at the Royal [...]
Researchers looked at data from nearly 2,000 randomly chosen people to determine if their circadian or biological clock rhythm (chronotype) affected what they ate and at what time. Clear differences in both energy and macronutrients between the two chronotypes abound, with morning people making healthier choices throughout the day. Evening types ate less protein overall and ate more sucrose in the morning. In the evening, they ate more sucrose, fat and saturated fatty acids.
Researchers are using artificial intelligence called fuzzy logic to get drones to navigate and land themselves on moving platforms. This holds promise for commercial uses such as delivering packages from moving vehicles.
Oregon experienced very low snowpack levels in 2014 and historically low snowpack levels in 2015. Now a new study suggests that these occurrences may not be anomalous in the future and could become much more common if average temperatures warm just two degrees (Celsius).
Scientists have created a three-dimensional organ-on-a-chip that can mimic the heart's amazing biomechanical properties in order to study cardiac disease, determine the effects that different drugs have on the heart and screen for new drugs to treat heart ailments.
A new study has shown evidence linking the biology of aging with idiopathic pulmonary fibrosis, a disease that impairs lung function and causes shortness of breath, fatigue, declining quality of life, and, ultimately, death. Researchers believe that these findings are the next step toward a possible therapy for individuals suffering from idiopathic pulmonary fibrosis.
Infections caused by a type of bacteria resistant to multiple antibiotics are occurring more frequently in US children and are associated with longer hospital stays and a trend towards greater risk of death, according to a new study.
The protein P-S6S240 may serve as an indicator of poor prognosis for patients with a hard-to-treat type of uterine sarcoma called leiomyosarcoma, and preclinical data suggest that patients whose tumors have this protein may respond to PI3K/mTOR inhibitors.
People who suffer long-term stress may also be more prone to obesity, according to research that involved examining hair samples for levels of cortisol, a hormone which regulates the body's response to stress.
A new study deployed 55 aircraft ocean instruments from the National Oceanographic Atmospheric Administration's WP-3D aircraft. The purpose of the scientific mission was to measure ocean temperature, salinity, and currents to understand the structure of these warm-water eddies.
A recently discovered fossil of a giant penguin with a body length of around 150 centimeters has been described in a new article. The new find dates back to the Paleocene era and, with an age of approximately 61 million years, counts among the oldest penguin fossils in the world. The bones differ significantly from those of other discoveries of the same age and indicate that the diversity of Paleocene penguins was higher than previously assumed. The team of scientists therefore postulates that the evolution of penguins started much earlier than previously thought, probably already during the age of dinosaurs.
Our blood stem cells generate around a thousand billion new blood cells every day. But the blood stem cells’ capacity to produce blood changes as we age. This leads to older people being more susceptible to anemia, lowered immunity and a greater risk of developing certain kinds of blood cancer. Now for the first time, a research team has succeeded in rejuvenating blood stem cells with established reduced function in aging mice.
A new study aimed at identifying areas of highest conservation priority in the world's oceans found six 'hot spots of marine biodiversity' that are severely impacted by climate change and fishing pressures.
