Phys.org / Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...
Phys.org / RNA droplets may have helped start life on Earth
It's one of the origins-of-life chicken-or-egg problems: How could RNA have helped give rise to the first cells before there were cells to contain it?
Phys.org / Hidden chemical pathway could keep phosphorus from fueling lake algal blooms
Why do some lakes remain plagued by harmful algal blooms even after phosphorus pollution has been reduced? Part of the answer lies beneath the surface. A new Concordia study has uncovered a previously overlooked chemical ...
Phys.org / Twenty years and 7,500 fossils reveal what blurs Earth's marine fossil record
In productive marine environments, a square meter (10.8 square feet) of seafloor can be perforated by hundreds to thousands of isolated and interconnected tunnels through which crawl and writhe a cornucopia of clams, shrimp, ...
Phys.org / Stellar spin may explain why repeated black hole flares grow dimmer
At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
Phys.org / Ocean plankton reveal sugar-for-nutrients partnership that sustains life in barren seas
In the vast, nutrient-poor regions of the world's oceans, there is a constant struggle for survival. Yet tiny organisms known as Collodaria have thrived there for millions of years. These Collodaria host microscopically small ...
Dialog / Seeing beneath the surface during metal additive manufacturing
When we watch a metal part being built by laser-based metal additive manufacturing (AM), we're only seeing part of the story. In one kind of metal AM process, a high-powered laser sweeps across a bed of metal powder, creating ...
Phys.org / Seeing the unseen: A new tool visualizes hidden structures in complex biological data
Modern biology research can now generate valuable data on an unprecedented scale. But there is one major obstacle: making sense of these complex high-dimensional datasets. A team at the University of Basel, Switzerland, has ...
Medical Xpress / Psychedelic exposure during adolescence disrupts a brain circuit linked to lasting social avoidance in rats
Psychedelics, drugs that alter people's perceptions, mood and thoughts, have recently shown promise for the treatment of some psychiatric disorders. Yet many psychedelic drugs remain controlled substances in most countries ...
Phys.org / Patience predicts longer education paths and faster earnings growth, real-money experiment finds
Some teenagers are happy to wait for a bigger reward tomorrow rather than cash in today. Others would rather take the sure thing now—or gamble on a risky, high-payoff bet. According to a new study, these everyday differences ...
Medical Xpress / Experimental drug shows promise in reversing high blood pressure's toll on kidneys and heart in mice
High blood pressure affects nearly 1 in 8 people worldwide, and its impact goes far beyond a number on a blood pressure monitor. It can quietly damage the heart, kidneys and brain, making it one of the world's biggest preventable ...
Phys.org / ALMA uncovers sulfur for the first time around a rare class of supergiant star
Astronomers have discovered a chemically rich collection of sulfur-bearing molecules surrounding the rare massive star HD 87643. The observations include the first detection of sulfur monoxide and sulfur dioxide around a ...
