Phys.org / Single ion maps 3D electromagnetic fields above chips with record sensitivity
Researchers at ETH Zurich have developed a method that uses a single ion to detect electromagnetic fields above a surface and to create a three-dimensional map of them. In the future, this approach can be used to improve ...
Medical Xpress / Zebrafish brains reveal alternate route for senses to the forebrain shared with mammals
Line up the brains of a fish, bird and a mammal, and something unexpected comes up. You do not see three different answers to the problem of making sense of the world. You see one answer, tilted three different ways. "You ...
Phys.org / Himalayan pangolin emerges as distinct species, confirmed with DNA from 19th-century specimen
The pangolin is a midsize mammal found only in Africa and Asia. The pangolins' scales make them unique, but these scales have become their undoing. Pangolins are poached for their scales, making them the most highly trafficked ...
Phys.org / Giant exoplanet may hold a magnetic grip on its host star
Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.
Phys.org / Spider venoms could stop deadly varroa mites killing honey bees
Spider venoms contain ingredients that could lead to a new treatment to protect honeybees from the deadly Varroa destructor mite, according to a study led by the University of the Sunshine Coast. Researchers identified components ...
Phys.org / Simulation reveals how glaciers transported rocks across the Alps 24,000 years ago
Many of the boulders scattered across the Swiss landscape did not originate where they now stand. Instead, they were carried by ice nearly 24,000 years ago. For the first time, researchers at the University of Lausanne (UNIL) ...
Medical Xpress / Molecules link lower weight babies and chronic diseases
Researchers have long sought to discover why babies who weigh less than expected at birth, a condition known as small for gestational age, or SGA, are at higher risk for heart, lung and metabolic diseases as adults.
Phys.org / How signals in the embryo tell cells what to become: A lab's final discovery
Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan Kettering Institute Developmental Biology Chair Kathryn Anderson, Ph.D., is publishing its final study.
Phys.org / When companies face hostile takeover threats, they turn to ESG, and the whole community benefits
When a company faces the prospect of a hostile takeover, its board may reach for traditional anti-takeover defenses. "Poison pills," for instance, allow existing shareholders to buy additional shares at a discount, diluting ...
Phys.org / Last-minute launch problem delays satellite rescue mission for NASA
A rush rescue mission to save a NASA space telescope remains grounded, this time because of a last-minute launch problem.
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Phys.org / Walkable, greener neighborhoods linked to better physical and mental health across the U.S.
A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents—especially when cities provide walking opportunities, greenery and mixed-use streets with a blend of commercial and residential ...
