| Plant-eating lizards on the cusp of tooth evolution Posted: 15 Oct 2021 03:43 PM PDT Researchers found that complex teeth, a hallmark of mammals, also evolved several times in reptiles, prompting the evolutionary success of plant-eating lizards. However, contrary to mammals their tooth evolution was not unidirectional. |
| Posted: 15 Oct 2021 03:42 PM PDT Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many organisms to head to the poles and form new communities -- with unforeseeable consequences for marine food webs. |
| Behavior resembling human ADHD seen in dogs Posted: 15 Oct 2021 03:42 PM PDT A study involving some 11,000 dogs demonstrated that the gender, age and breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD). |
| Flu and heart disease: The surprising connection that should convince you to schedule your shot Posted: 15 Oct 2021 03:42 PM PDT Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiovascular risks. |
| Cellular environments shape molecular architecture Posted: 15 Oct 2021 08:12 AM PDT An important cellular structure called the nuclear pore complex (NPC) has larger dimensions than previously thought. A research team made this discovery using cryo-focused ion beam (cryo-FIB) milling and cryo-electron tomography (cryo-ET) -- which allowed them to analyze the NPC directly inside cells. |
| Plant-based jet fuel could reduce emissions by 68% Posted: 14 Oct 2021 02:27 PM PDT Replacing petroleum-based aviation fuel with sustainable aviation fuel derived from a type of mustard plant can reduce carbon emissions by up to 68%, according to new research. |
| Hedges reduce pollution at breathing height in shallow street canyons, study confirms Posted: 14 Oct 2021 10:12 AM PDT An extensive field study into air quality along a road lined with buildings has confirmed that hedges can help mitigate traffic-related pollution up to 1.7m, reducing the pollutants breathed by pedestrians, young children and cyclists. |
| Possible alternative treatment for Lyme disease Posted: 14 Oct 2021 10:11 AM PDT Researchers have described a new antibiotic that appears to have the potential to cure Lyme disease. |
| Clues emerge: How harmless bacteria go rogue turning into deadly flesh-eating variants Posted: 14 Oct 2021 10:11 AM PDT A new study found that the environmental lifestyle that bacteria possess reveal why some go rogue and turn deadly while others remain harmless to humans. The findings focus on Vibrio vulnificus, better known as the flesh-eating bacteria. However, what the scientists found could help create a model that may well extend to other human pathogens. |
| New statistical study finds link between protein evolution and thermal variation Posted: 14 Oct 2021 08:12 AM PDT A recent statistical study has revealed some of the constraints and directions in the evolution of the structure and function of proteins. Better models of protein structural dynamics may allow researchers to understand more of this fundamental mystery in living organisms. |
| Ranking healthfulness of foods from first to worst Posted: 14 Oct 2021 08:12 AM PDT Food Compass, a new nutrient profiling system, rates the healthfulness of foods, beverages, and mixed meals on a score of 1-100 based on a wide range of science-based attributes. This adaptable tool aims to encourage healthier choices, spur industry reformulation, and guide nutrition policies. |
| Scientists map brain circuit that drives activity in fertile females Posted: 14 Oct 2021 07:20 AM PDT Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile. |
| Cell-based influenza vaccine provides protection against the flu in children Posted: 14 Oct 2021 07:20 AM PDT A cell-based influenza vaccine has effectively provided protection against the flu in children and adolescents, according to a new study. |
| Sustainable farming: There’s no one solution Posted: 14 Oct 2021 07:02 AM PDT Sustainable agriculture will not be achieved by one universal solution. A meta-analysis shows that the current focus on no-till farming does not achieve the desired results. A sustainable system of agriculture must be designed for local needs and in dialog with local farmers. |
