Tech Xplore / Laser-etched glass can store data for 10,000 years, Microsoft says
Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.
Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
Phys.org / How a certain form of dark matter may lead to the generation of cosmological magnetic fields
Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. ...
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Phys.org / One of the ocean's saltiest regions is freshening: What it means for circulation
The southern Indian Ocean off the west coast of Australia is becoming less salty at an astonishing rate, largely due to climate change, new research shows.
Phys.org / The Hubble tension: How magnetic fields could help solve one of the universe's biggest mysteries
It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.
Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
Phys.org / Astronomers may have just found one of the missing links in galaxy evolution
A team of 48 astronomers from 14 countries, led by the University of Massachusetts Amherst, has discovered a population of dusty, star-forming galaxies at the far edges of the universe that formed only a billion years after ...
Phys.org / Replacing humans with machines is leaving truckloads of food stranded and unusable
Supermarket shelves can look full despite the food systems underneath them being under strain. Fruit may be stacked neatly, chilled meat may be in place. It appears that supply chains are functioning well. But appearances ...
Phys.org / Is dark energy actually evolving?
Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing the expansion of the ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / A super stable laser on the moon could guide future lunar missions and improve our timekeeping
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, ...
