Biology Genetically-engineered mosquitoes suppress survival of their kind, in field trials designed to reduce mosquito-borne diseases
Biology A clam presumed extinct for 40,000 years has been found alive. Known as Cymatioa cooki, the clam had only ever been found as a fossil, and scientists presumed that the species had been extinct for more than 40,000 years.
Biology Deer-vehicle collisions spike when daylight saving time ends. The change to standard time in autumn corresponds with an average 16 percent increase in deer-vehicle collisions in the United States.The researchers estimate that eliminating the switch could save nearly 37,000 deer — and 33 human lives.
Biology Danish study found that children who have expressed a desire at the age of 11 to be a different gender enter puberty earlier than their peers. In the study, both birth-assigned boys and girls with a previous expressed desire to change gender entered puberty around two months earlier than their peers
Biology Scientists find biomarkers of cuproptosis, a very novel form of regulated cell death, predict autism spectrum disorder with 90% accuracy
Biology A review concluded that "marijuana can cause bronchitis, but a moderate body of literature suggests that distal airway/parenchymal lung disease does not occur; marijuana does not cause chronic obstructive pulmonary disease and probably does not cause lung cancer, distinctly different from tobacco."
Biology World’s heaviest bird may be self-medicating on plants used in traditional medicine. Study suggests that great bustards actively seek out two plants with compounds that can kill pathogens. They may thus be a rare example of a bird that uses plants against disease – that is, self-medication.
Biology Peer-Reviewed Study: Healthy Plant-Based Diets "Significantly Increase Sperm Density and Motility"
Biology A new study focuses on the crucial question of why people are more vulnerable to catching colds during the months of winter. The answer hinges on an evolved defense system, innate to the human nose, that is numbed by frigid temperatures.
Biology Newly discovered “social fluid” unites ants across developmental stages into one, colony-wide superorganism. The study, published in Nature, describes how larvae rely on the fluid to grow and how, if they fail to drink it, intermediate-stage pupae die before reaching adulthood.
Biology Neanderthals appear to have been carnivores: Researchers have for the first time used zinc isotope analysis to determine the position of Neanderthals in the food chain. Their findings suggest that they were in fact carnivores.
Biology Low-protein highly processed foods lead to higher energy intake because of the biological response to macronutrient imbalance driven by a dominant appetite for protein. This study supports a central role for protein in the obesity epidemiconlinelibrary.wiley.com
Biology Dancers pick up the pace on a bass beat — even though it’s inaudible. Concertgoers were not conscious of a low-frequency sound, but grooved more energetically when it played.
