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 / 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 / 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 / X-ray analysis reveals the inner life of leaves while advancing engineering efforts to reduce 'crop sweat'
In the Midwestern summer, humans and plants have to breathe through the heat and humidity. Researchers hope that a retooled crop plant—one with an improved ventilation system within its leaves—could thrive while avoiding ...
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 / Today's Mediterranean diet leans on olive oil, veggies and fish—But the ancients mainly ate bread
The Roman emperor Julian (332–363 CE) called bread the food that "among us is thought to be the most nourishing."
Phys.org / Japan's earthquake shows extreme heat can turn one disaster into two
Emergency workers attempting to rescue survivors after a recent earthquake in Kyushu, Japan, also had to cope with extreme summer heat.
Phys.org / Three energy-loss routes may explain Tarantula Nebula's X-ray shortfall
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the ...
Medical Xpress / Air pollution-linked blood changes detected years before lung cancer diagnosis
A new study, published Tuesday in Nature Communications, found measurable changes in people's blood associated with exposure to air pollution and the subsequent development of lung cancer. The findings provide promising clues ...
Phys.org / Fungal chitin offers new route to tougher hydrogels for medical devices and soft robots
Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) and the University of Tennessee (UT), Knoxville, have made an advance by using a natural substance from fungi called chitin to create hydrogels ...
Medical Xpress / Long before adulthood, a chemical mark may quietly shape how the brain handles stress
Stress or trauma during childhood may leave people more vulnerable to mental health struggles and stress later in life. Scientists think one reason could be that early-life stress leaves lasting molecular bookmarks on DNA, ...
Phys.org / Major genetic weakness threatens future corn breeding, study reveals
A new study led by University of Illinois Urbana-Champaign scientists reveals critically low genetic variation in one of the country's primary breeding stocks for corn. The finding relates specifically to grain yield in intermediate-maturity ...
