Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / Perceived naturalness emerges as key driver of public support for climate technology
From nuclear energy to lab-grown meat, the list of effective but unpopular climate solutions is long. A new University of Colorado Boulder study sheds light on why people reject or accept some proposed sustainability technologies: ...
Phys.org / Star cluster discovery could change how scientists measure the universe
University of Missouri researchers have uncovered evidence that challenges one of astronomy's most trusted assumptions, a breakthrough that could reshape how scientists measure galaxies and reconstruct the history of the ...
Phys.org / More than a decade of observation in Seattle suburbs shows where sensitive bird species won't go
Nearly 30 years ago, a simple question sent University of Washington researchers into the Puget Sound lowlands to look for birds. With Seattle's population swelling and housing developments pushing into once-forested suburbs, ...
Phys.org / Beyond color: Fluorescence lifetime imaging distinguishes multiple proteins in living plant cells
Fluorescent protein imaging is an indispensable tool in life science research, enabling visualization of protein movement and localization, gene expression, signaling pathways, protein-protein interactions and more. For simultaneous ...
Phys.org / Early farmers' larger grains may reflect rainfall, not genetic selection
A new archaeobotanical study by researchers from the University of Oxford and Kiel University (CAU) has revealed that increases in cereal grain size at the dawn of agriculture, more than 11,000 years ago, were initially driven ...
Phys.org / First evidence of Neanderthal bone tool use in Romania discovered
Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.
Phys.org / Under-the-radar creeks could be sweeping carbon out of salt marshes
Salt marshes are coastal wetlands that are alternately inundated and exposed by tides. These marshes, like other coastal ecosystems, are hotspots of carbon cycling.
Phys.org / Scientists uncover a hidden mechanism that drives RNA synthesis
Scientists have long been fascinated by two promising classes of antibiotics that disable RNA polymerase (RNAP). They knew that these drugs could grind gene expression to a halt in several pathogens, including the bacterium ...
Phys.org / Porous material can arrange disordered gas molecules into a crystal-like structure, study predicts
Capturing carbon or storing hydrogen to combat global warming requires compressing gases into sponge-like porous materials. Until now, gas molecules were thought to adsorb in a disordered manner throughout the pores. But ...
Phys.org / Twisted magnetic field around newborn star confirms decades-old jet theory
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) is a partner, have captured the first direct, high-resolution ...
Phys.org / Webb reveals oxygen-rich dust and water surviving near Milky Way's central black hole
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky ...
