| How fasting diets could harm future generations Posted: 11 May 2021 05:11 PM PDT New research which shows that fasting diets could harm the health of future generations. Fasting diets have risen in popularity in recent years, however little is known about the long-term impact of these diets, particularly for future generations. The new study reveals that reduced food intake in roundworms has a detrimental effect on three generations of offspring - particularly when those descendants have access to unlimited food. |
| Newly described horned dinosaur from New Mexico was the earliest of its kind Posted: 11 May 2021 01:07 PM PDT With a frilled head and beaked face, Menefeeceratops sealeyi lived 82 million years ago, predating its relative, Triceratops. |
| How one of the oldest natural insecticides keeps mosquitoes away Posted: 11 May 2021 01:07 PM PDT A new study has identified a scent receptor in mosquitoes that helps them sniff out and avoid trace amounts of pyrethrum, a plant extract used for centuries to repel biting insects. These findings could help researchers develop new broad spectrum repellents to keep a variety of mosquito species at bay, and by extension stop them from biting people and spreading disease. |
| Posted: 11 May 2021 09:38 AM PDT Scientists describe a fossil skeleton of an ancient shark, which is assigned to a new, previously unknown genus and species. |
| Lichens slow to return after wildfire Posted: 11 May 2021 09:36 AM PDT Lichen communities may take decades -- and in some cases up to a century -- to fully return to chaparral ecosystems after wildfire. |
| Discovering candidate for reflex network of walking cats: Understanding animals with robots Posted: 11 May 2021 09:35 AM PDT A group of researchers developed a quadruped robot platform that can reproduce the neuromuscular dynamics of animals, discovering that a steady gait and experimental behaviors of walking cats emerged from the reflex circuit in walking experiments on this robot. |
| How to predict severe influenza in hospitalized patients Posted: 11 May 2021 09:35 AM PDT Researchers have identified predictors of both severe disease and recovery in hospitalized influenza patients, finding that the immune system works in concert to fight influenza. |
| Quantum mechanics paves the way for more stable organic solar cells Posted: 11 May 2021 09:35 AM PDT Quantum mechanics can be used to create more stable and more easily produced organic solar cells. |
| Protecting local water has global benefits Posted: 11 May 2021 06:20 AM PDT A new article demonstrates why keeping local lakes and other waterbodies clean produces cost-effective benefits locally and globally. |
| New material to treat wounds can protect against resistant bacteria Posted: 11 May 2021 05:12 AM PDT Researchers have developed a new material that prevents infections in wounds - a specially designed hydrogel, that works against all types of bacteria, including antibiotic-resistant ones. The new material offers great hope for combating a growing global problem. |
| Glyphosate inhibits symbiotic bacteria in the saw-toothed grain beetle Posted: 11 May 2021 05:12 AM PDT Susceptibility of their microbial partners to the herbicide may be an underestimated weak spot of insects that could add to their decline. |
| Hidden within African diamonds, a billion-plus years of deep-earth history Posted: 11 May 2021 05:12 AM PDT A team has come up with a way to solve two longstanding puzzles: the ages of individual fluid-bearing diamonds, and the chemistry of their parent material. The research has allowed them to sketch out geologic events going back more than a billion years -- a potential breakthrough not only in the study of diamonds, but of planetary evolution. |
| Researchers develop magnetic thin film for spin-thermoelectric energy conversion Posted: 11 May 2021 05:11 AM PDT Engineers have proposed a satellite-aided drought monitoring method that can adequately represent the complex drought conditions into a single integrated drought index. |
| Sex cells in parasites are doing their own thing Posted: 11 May 2021 05:11 AM PDT Researchers have discovered how microbes responsible for human African sleeping sickness produce sex cells. |
| The Aqueduct of Constantinople: Managing the longest water channel of the ancient world Posted: 11 May 2021 05:11 AM PDT Aqueducts are very impressive examples of the art of construction in the Roman Empire. Even today, they still provide us with new insights into aesthetic, practical, and technical aspects of construction and use. Scientists investigated the longest aqueduct of the time, the 426-kilometer-long Aqueduct of Valens supplying Constantinople, and revealed new insights into how this structure was maintained back in time. |
| Team 'reads minds' to understand human tool use Posted: 10 May 2021 10:32 AM PDT Researchers have made an astonishing new discovery about how our brains control our hands. The team used MRI data to study which parts of the brain are used when we handle tools. The findings could help shed light on the regions of the brain that evolved in humans and set us apart from primates, and could pave the way for the development of next-generation prosthetic limbs that tap into the brain's control center. |
| Bacteria do not colonize the gut before birth Posted: 10 May 2021 10:31 AM PDT Researchers examined prenatal stool (meconium) samples collected from 20 babies during breech Cesarean delivery. By including only breech caesarean deliveries in healthy pregnant women they were able to avoid the transmission of bacteria that occurs naturally during a vaginal birth. |
