Phys.org / MIZ-ing in action: How much of Antarctic sea ice is affected by waves?
Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and crucial region of the Antarctic sea-ice system for the first time. The Marginal Ice Zone (MIZ) ...
Phys.org / New Gulf Coast plan uses ocean technology to trap carbon dioxide
The motion of the ocean may be the key to removing carbon dioxide from the atmosphere, so University of Houston researchers set out to determine which U.S. coastlines are best suited for the process in a new study.
Phys.org / Green stones buried with Panama's ancient chiefs confirmed as Colombian emeralds
More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have ...
Phys.org / The solar wind's secret hammerheads and what they tell us about heat in space
The proton sharks showed up on a Friday. In a routine data calibration meeting for NASA's Parker Solar Probe in 2020, a small group of scientists were scrolling through visualizations of their data showing solar winds. Suddenly, ...
Phys.org / How bean plants call on wasps for help when hungry caterpillars attack
Some plants are not the sitting ducks they appear to be when they come under attack. If a hungry caterpillar starts to chomp on the succulent leaves of a common bean plant, a highly sophisticated defense system kicks into ...
Phys.org / Electrical pulses reverse aging in sea squirts, offering clues for extending human longevity
A tiny sea creature might hold the secret to reversing the aging process. When treated with a brief series of electrical pulses, sea squirts experience dramatic and long-lasting health improvements that can significantly ...
Phys.org / Bare supercontinent may have tipped ancient Earth into 'Snowball' phase
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped ...
Phys.org / The generation of massive Schrödinger cat states using ultracold atoms
Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, specifically at the scale of atoms and subatomic particles. An effect predicted by the laws of quantum mechanics ...
Phys.org / Hailstorms could grow more dangerous and damaging with climate change
Hailstorms can be incredibly dangerous, posing risks to life and property. Then there's the economic damage to cars, crops, and infrastructure caused by large balls of ice falling at high speed from the sky. And the problems ...
Phys.org / Ripples in fire-ant collectives suggest motions are driven by neighbor alignments
Researchers in Spain have discovered that in collectives of moving fire ants, rippling "waves" of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.
Phys.org / New MRI sensors detect target molecules in the brain and body with high sensitivity
When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body's muscles, organs, and bones. It can monitor blood flow ...
Phys.org / Introduced wild pigs linked to fewer invasive plants, while native deer show the opposite pattern
Wild pigs are generally considered among the world's most problematic invasive mammals. But a major new study from Aarhus Universitet shows that the introduced animals may actually have beneficial effects in North American ...
