Phys.org / Manakins' dazzling dances may owe their origins to an ancient diet shift
Few animals put on a show quite like manakins. In the rainforests of Central and South America, males of these small tropical birds, with strikingly bright plumage, often gather at communal display sites (leks), where they ...
Phys.org / Light-programmed system projects 28-layer 3D images in single shot
Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a ...
Phys.org / Interpretable AI in materials discovery: Uncovering how models make predictions
A method to interpret artificial intelligence (AI) models used in materials discovery by analyzing their learned features has been developed by researchers from Japan. The method extracts key features from an AI model trained ...
Phys.org / New tool to help build more reliable DNA nanostructures
Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with biological systems, they could ...
Phys.org / Damaged boreal peatlands may triple methane emissions, reshaping climate risk
A new study reveals that, for the first time, areas of Canada's boreal peatlands damaged by oil and gas exploration have failed to recover as scientists and companies predicted and instead have led to a tripling of methane ...
Phys.org / NASA's Chandra discovers possible supernova remnant in galactic center
Using data from NASA's Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings was published in The Astrophysical ...
Phys.org / Canary Island relics offer new clues into how North African cultures adapted to ocean living
Archaeological evidence from the Canary Islands suggests that by the 11th century, people there were harvesting and processing a variety of fish and other marine organisms—indicating that coastal resources may have played ...
Phys.org / Chemical impurities make carbon surfaces superslippery, researchers find
Engineers often treat impurities as a problem to eliminate to improve material performance. But new research from Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM suggests that in some ...
Phys.org / Harmonic radar tags reveal how mosquitoes move through fields and parkland
It's an insect everybody loves to hate. Pesky mosquitoes will be out in swarms as the weather warms up across the U.S.—and their bites aren't just itchy. They can transmit pathogens that can cause diseases like West Nile ...
Phys.org / Fusion reactors could be monitored for covert plutonium production
In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly ...
Phys.org / Chandra resolves NGC 6540's mysterious X-ray flare into three separate sources
Using NASA's Chandra X-ray spacecraft, astronomers have performed deep X-ray observations of a galactic globular cluster known as NGC 6540. The new observational campaign, described June 1 on the preprint server arXiv, focused ...
Phys.org / El Niño arrives and could rank among strongest events since 1950
The phenomenon El Niño has arrived, the U.S. weather agency said Thursday, and scientists expect the pattern, synonymous with droughts, floods and soaring temperatures, will intensify through the end of the year, potentially ...
