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 / Bioengineers build branched, perfusable kidney collecting ducts using 3D bioprinting
The human kidney filters about a cup of blood every minute, removing waste, excess fluid, and toxins from it, while also regulating blood pressure, balancing important electrolytes, activating Vitamin D, and helping the body ...
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 / Mitochondrial superoxide signal helps preserve the nuclear envelope and delay aging, study finds
The nuclear envelope (NE) is a dynamic and selective barrier that organizes genome function and nucleocytoplasmic communication, and its structural deterioration is a hallmark of aging associated with diverse human diseases. ...
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 / How fast can a microlaser switch 'modes?' A simple rule reveals a power-law time scaling
Modern technologies increasingly rely on light sources that can be reconfigured on demand. Think of microlasers that can quickly switch between different operating states—much like a car shifting gears—so that an optical ...
Phys.org / Simple at-home tests strips can detect cat and dog viruses
Pet owners want quick answers when their beloved cat or dog is sick. And if these furry friends are experiencing digestive distress, lethargy and fever, it's important to rapidly rule out serious illnesses like feline panleukopenia ...
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 / 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 / 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 / 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 ...
