Phys.org / Circular polarization could cut laser backscatter in fusion experiments
Experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the ...
Phys.org / Fermi mission uncovers possible sibling supernova remnants
A new study of two supernova remnants, the debris left behind after stars explode, suggests the explosions came from stellar siblings that once orbited each other. The first star's detonation sent its binary companion hurtling ...
Phys.org / Hidden fungus inside desert moss could rewrite 470-million-year story of how plants moved onto land
Mosses are survivors. They can dry into what looks like green dust, only to spring back to life minutes after rain. They can grow on rocks, in deserts, and there's talk of using them to terraform Mars someday. According to ...
Phys.org / Alpha Magnetic Spectrometer reveals four cosmic ray classes across 20 elements, defying current models
Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life. In fact, the star may ...
Phys.org / Rice gene switch helps plants rebound from cold and use nitrogen more efficiently
Global climate change has increased the frequency of regional cold spells, causing substantial yield losses and even crop failure. Meanwhile, excessive nitrogen fertilizer use in agriculture has increased non-point-source ...
Phys.org / How a telescope's mirror stability makes or breaks exoplanet detection
Finding life beyond our solar system is a major goal of modern astronomy. NASA's planned Habitable Worlds Observatory (HWO) aims to take direct images of Earth-sized planets around stars other than our sun. This task, however, ...
Phys.org / Trace additive unlocks faster bioplastic biodegradation without losing transparency or strength
Compostable plastics could be part of a solution to the world's plastic waste problem. But currently these materials need industrial composting facilities to break down. In a step toward making a home-compostable plastic, ...
Phys.org / Mating reveals cholesterol's hidden role in male fruit fly lifespan
Scientists have discovered that the optimal diet for male fruit flies may depend strongly on whether they are reproducing, challenging long-standing assumptions about nutrition and aging. Led by researchers from the University ...
Phys.org / Heat waves increase wildfire risk—a new study explains how much, and it's not a small number
When heat waves hit the Western United States, the risk of wildfires quickly rises. The prolonged heat dries out vegetation, but that's only part of the cause—heat waves also play other roles in spreading wildfires.
Phys.org / Missing DNA replication step revealed in first image of pre-initiation complex
Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick has recorded the missing ...
Phys.org / Describing past relationship as a story may help women process breakups
Breaking up with a loved one is often a painful life experience, one that is difficult to recover from. Researchers from SWPS University, however, suggest that a simple step can help. Writing down the story of a past relationship ...
Phys.org / People are marrying holograms and making friends with chatbots. But can AI bring true happiness?
Can technology really replace human relationships? As philosophy scholars who focus on human happiness and on artificial intelligence (AI), we tackle this question in a recent paper.
