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 / Tibet's tectonic clash: New satellite view suggests weaker fault lines
A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth's fault lines are far weaker and the continents are less rigid than scientists previously thought. This finding is based on ground-monitoring ...
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 / 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 ...
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 / 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 / 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 / Unraveling the physics behind Kamchatka's 73-year earthquake cycle
A research team from University of Tsukuba and collaborating institutions has clarified why M9-class megathrust earthquakes recur off the Kamchatka Peninsula with an unusually short cycle of 73 years. By analyzing the rupture ...
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 ...
Dialog / Using data to reduce subjectivity in landslide susceptibility mapping
In recent years, numerous landslides on hillsides in urban and rural areas have underscored that understanding and predicting these phenomena is more than an academic curiosity—it is a human necessity. When unstable slopes ...
