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 / 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 / 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 / Not all humans are 'super-scary' to wildlife, animal behavior study suggests
Humans have climbed to the top of the food chain by skillfully hunting, trapping, and fishing for other animals at scales that far exceed other predators, altering how the animals behave and earning the tag of a "super-predator." ...
Phys.org / First-ever shark recorded in Antarctic waters filmed at 490 meters in near‑freezing water
An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun's rays to illuminate was an unexpected sight.
Phys.org / AI system TongGeometry generates and solves olympiad-level geometry problems
The International Mathematical Olympiad (IMO) is a prestigious competition featuring talented high school students from around the world, in which competitors solve complicated mathematical problems. Geometry problems from ...
Tech Xplore / Robot hand approaches human-like dexterity with new visual-tactile training
Human hands are a wonder of nature and unmatched in the animal kingdom. They can twist caps, flick switches, handle tiny objects with ease, and perform thousands of tasks every day. Robot hands struggle to keep up. They typically ...
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 ...
Tech Xplore / Ultrafast 3D printing method creates complex objects in under a second
High-speed 3D printing has just gotten a lot faster. Researchers from Tsinghua University in China have developed a new high-speed printing technology capable of creating complex millimeter-scale objects in just 0.6 seconds. ...
Phys.org / Antarctic ice melt can change global ocean circulation, sediment cores suggest
A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in the Southern Ocean. The ...
