Scientists uncover a surprising connection between number theory and evolutionary genetics
Number theory, the study of the properties of positive integers, is perhaps the purest form of mathematics. At first sight, it may seem far too abstract to apply to the natural world. In fact, the influential American number theorist Leonard Dickson.....»»
Genetics provide key to fight crown-of-thorns starfish
Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a University of Queensland study into the pest's genetics......»»
New research employs shutter speed analogies to validate 55-year-old theory about chemical reaction rates
Chemical reactions are commonly depicted as transitions from reactants to products. However, such reactions involve many molecules, and the individual molecules themselves undergo frequently-occurring structural changes as they transform from the rea.....»»

Tiger beetles fight off bat attacks with ultrasonic mimicry
Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat echolocation. To date, scientists have found at leas.....»»

In a study published in PeerJ, scientists have revealed the intricate vocal patterns of Bornean orangutans, shedding new light on the complexities of their communication. Titled "Vocal Complexity in the Long Calls of Bornean Orangutans," the research.....»»
Study discovers distinct population of "troublemaker" platelet cells appear with aging
As people age, they become more prone to blood clotting diseases, when blood cells called platelets clump together when they don't need to and can cause major issues such as strokes and cardiovascular disease. For decades, scientists have studied why.....»»
Using AI to speed up and improve the most computationally-intensive aspects of plasma physics in fusion
The intricate dance of atoms fusing and releasing energy has fascinated scientists for decades. Now, human ingenuity and artificial intelligence are coming together at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) t.....»»
Scientists develop sticky pesticide to combat pest insects
Researchers from Wageningen University & Research (WUR) and Leiden University have engineered a biological barrier that protects plants from diseases and pests. It concerns a sticky substance that is sprayed on leaves, to which pests stick......»»
Scientists create an "optical conveyor belt" for quasiparticles
Using interference between two lasers, a research group led by scientists from RIKEN and NTT Research have created an "optical conveyor belt" that can move polaritons—a type of light-matter hybrid particle—in semiconductor-based microcavities. Th.....»»
