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 ...
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 / Real-time view inside microreactor reveals 2D semiconductor growth secrets
As the miniaturization of silicon-based semiconductor devices approaches fundamental physical limits, the electronics industry faces an urgent need for alternative materials that can deliver higher integration and lower power ...
Phys.org / Complex tongue bones, fleshy teeth on the roof of earliest known bird's mouth might have helped it snag food
Flying is really hard work. Compared to walking, swimming, or running, flying is the form of movement that takes the most energy and requires the most calories. That means that birds have had to evolve specialized ways to ...
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 / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
