Phys.org / First evidence of a subsurface lava tube on Venus
Volcanic activity is not unique to Earth: traces of volcanic activity, such as lava tubes, have been found on Mars and the moon. Now, the University of Trento has demonstrated the existence of an empty lava tube even in the ...
Phys.org / Wireless sensor assesses subsoil health in effort to cut costs and refine farming
A new smart platform invented by Purdue University researchers to wirelessly monitor subsoil health could change the landscape of agricultural sensing systems. The invention addresses a critical need in agriculture nationwide: ...
Phys.org / Bee bandits: How a yeast influences nectar-robbing behavior in bumble bees
From fundamental biological units as tiny as genes to complex societies, ecological systems rely on cooperation. All manner of organisms can benefit from working together to survive in a dog-eat-dog world. "Mutualism is a ...
Phys.org / Eco-friendly catalyst switches oxygen source based on particle size, study finds
As the climate crisis becomes a part of daily life with unprecedented heat waves and cold snaps, technology to effectively remove greenhouse gases is emerging as a critical global challenge. In particular, catalytic technology ...
Phys.org / Deep-sea microbes get unexpected energy boost from marine snow, researchers discover
For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that ...
Phys.org / 3D 'polar chiral bobbers' identified in ferroelectric thin films
A novel type of three-dimensional (3D) polar topological structure, termed the "polar chiral bobber," has been discovered in ferroelectric oxide thin films, demonstrating promising potential for high-density multistate non-volatile ...
Phys.org / DeepChopper model improves RNA sequencing research by mitigating chimera artifacts
Scientists in the laboratory of Rendong Yang, Ph.D., associate professor of Urology, have developed a new large language model that can interpret transcriptomic data in cancer cell lines more accurately than conventional ...
Phys.org / A quick stretch switches this polymer's capacity to transport heat
Most materials have an inherent capacity to handle heat. Plastic, for instance, is typically a poor thermal conductor, whereas materials like marble move heat more efficiently. If you were to place one hand on a marble countertop ...
Phys.org / Why does rough grinding make stainless steel more prone to corrosion?
Stainless steel is widely known for its impressive corrosion resistance, but it is not invincible. When exposed to environments containing chloride ions, such as seawater, the risk of corrosion increases. To achieve the sleek, ...
Phys.org / Nanodevice tugs single proteins to reveal how cells sense force
Physical forces from gravity, muscle contraction, and more have strong impacts on how the cells in our bodies behave. For instance, weight-bearing exercise helps stave off osteoporosis because cells in our bones sense that ...
Phys.org / Capturing the instant of electrical switching to pave the way for faster memory
As artificial intelligence advances, computers demand faster and more efficient memory. The key to ultra-high-speed, low-power semiconductors lies in the "switching" principle—the mechanism by which memory materials turn ...
Phys.org / How the spring thaw influences arsenic levels in lakes
From 1948 to 1953, a gold mine called Giant Mine released about 5 tons of arsenic trioxide per day into the environment around Yellowknife, Northwest Territories, Canada. Emissions declined from the 1950s until the mine closed ...
