Phys.org / Removing livestock from grasslands could compromise long-term soil carbon storage
Removing sheep and other livestock entirely from upland grasslands—a strategy often promoted as a way to boost carbon storage and tackle climate change—may actually reduce the most stable forms of soil carbon, according ...
Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena
The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...
Phys.org / Focusing and defocusing light without a lens: First demonstration of the structured Montgomery effect in free space
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, all without the use of ...
Phys.org / Jupiter's slimmer profile: Giant planet revealed to be narrower at equator
For over 50 years, we thought we knew the size and shape of Jupiter, the solar system's largest planet. Now, Weizmann Institute of Science researchers have revised that knowledge using new data and technology. In a new study ...
Phys.org / Tiny new dinosaur Foskeia pelendonum fills in an evolutionary gap
An international team has described Foskeia pelendonum, a tiny Early Cretaceous ornithopod from Vegagete (Burgos, Spain), measuring barely half a meter long. Led by Paul-Emile Dieudonné (National University of Río Negro, ...
Phys.org / Some tropical land may heat up nearly twice as much as oceans under climate change, sediment record suggests
Some tropical land regions may warm more dramatically than previously predicted, as climate change progresses, according to a new CU Boulder study that looks millions of years into Earth's past. Using lake sediments from ...
Phys.org / Cells adapt to aging by actively remodeling endoplasmic reticulum, study reveals
Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of life, but it is associated ...
Phys.org / Biochemists find solution that lets bacteriophages bypass bacterial immunity
Antimicrobial resistance—when bacteria and fungi defend themselves against the drugs designed to kill them—is an urgent threat to global public health, according to the Centers for Disease Control and Prevention. To combat ...
Phys.org / Unexpected climate feedback links Antarctic ice sheet with reduced carbon uptake
A study in Nature Geoscience reveals that changes in the West Antarctic Ice Sheet (WAIS) closely tracked marine algae growth in the Southern Ocean over previous glacial cycles, but not in the way scientists expected. The ...
Phys.org / Machine learning accelerates plasma mirror design for high-power lasers
Plasma mirrors capable of withstanding the intensity of powerful lasers are being designed through an emerging machine learning framework. Researchers in Physics and Computer Science at the University of Strathclyde have ...
Phys.org / Natural magnetic materials can control light in unprecedented ways
Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction, could transform ...
Phys.org / Bubble bots: Simple biocompatible microrobots autonomously target tumors
The potential of microrobots is enormous. These miniature objects can be designed to carry out actions within the body, such as sensing biomarkers, manipulating objects like blood clots, or delivering drug therapies to tumor ...
