Hiroshima blast debris reveals a previously unknown alloy
The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly produce materials that could never form under
Drone cameras can measure pigments indicating surface health of dryland soils
Drylands soils are being degraded by human activities and climate change, threatening the thin living layers covering their surface, called biocrusts, according to the U.S. Geological Survey. Composed of cyanobacteria, lichens, mosses, algae, fungi and bacteria, biocrusts play
Does misinformation on Facebook and Instagram change what you believe?
For years, social media companies have faced pressure from users and government watchdogs to stop misinformation from distorting elections, deepening political divisions and undermining Americans' trust in institutions. But what if dramatically reducing people's exposure to
One LED produces four stable colors at room temperature
Full-color displays normally require separate red, green and blue light emitters. A team from the University of Osaka and Ritsumeikan University has demonstrated another approach: a single light-emitting layer that produces several colors when electrically powered at room
New research shows the Golgi complex is involved in DNA repair control
Our DNA is under constant threat. Chemicals, radiation and the everyday errors of cell division all damage it, and if left unrepaired, this can lead to diseases such as cancer. Cells invest heavily in finding and fixing these errors. A new study from EMBL Heidelberg's Pepperkok
Neptune's inner moons may be shattered remains of ancient icy worlds
In 1989, the Voyager 2 mission discovered six new moons orbiting Neptune, including five tiny ones that orbit just outside the planet's main rings. Because of their small sizes and locations, these satellites have been difficult to study from Earth. Now, using NASA's James Webb

What if the brain does not create consciousness?
Christof Koch is taking on one of science’s deepest mysteries: how the brain creates conscious experience, or whether it creates it at all. He argues that materialism has yet to solve this “hard problem” and will explore puzzling phenomena such as near-death experiences and

This 4,000-year-old city defied the rules of history
As Mohenjo-daro prospered, the gap between its richest and poorest households actually shrank. Its shared infrastructure, fair trade systems, and lack of powerful royal elites suggest that equality may have helped fuel the ancient city’s success.
Mapping endangered habitats with the help of citizen scientists and satellite data
As biodiversity declines and many of the UK's most important habitats become smaller and more fragmented, conservation organizations need accurate, up-to-date maps to protect wildlife and restore nature. However, creating these maps by surveying every site on foot is
Two Arctic charr populations evolved in less than a century, study finds
Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster pace, particularly when they are isolated from other

A canopy call, a partial photo and DNA revealed a new primate species — one that may already be at risk of extinction.
Rice bran compound may help ease irritable bowel symptoms
A compound in rice bran may help calm an overactive gut by reducing the calcium signals that cause intestinal muscles to contract. Ferulic acid suppressed contractions triggered by several chemical messengers in laboratory experiments. The discovery could eventually support new
First dogs in the UK treated with new bee and wasp venom immunotherapy
The University of Glasgow's Small Animal Hospital is the first in the UK to use a treatment for dogs suffering from serious allergic reactions to bee and wasp stings. The treatment, Hymenoptera Venom Immunotherapy (VIT), has now been successfully used on a number of patients,
Research finds exposure to 'untrustworthy' social media is rare, the fine print is less reassuring
How much of what you see on social media comes from sources that repeatedly post falsehoods? And if that content quietly vanished from your feed, would you believe anything different months later?
Tread softly: A new 'light touch' way to detect kauri dieback
Kauri dieback is one of the most serious threats facing Aotearoa New Zealand's kauri forests. The disease is caused by a soil-dwelling microbe, Phytophthora agathidicida, which infects kauri roots and eventually kills the tree. There is no cure, so finding infected trees early
Scientists found evolution repeating itself in the Galápagos Islands
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise. Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes. Researchers also found

Physicists create Bose–Einstein condensate from ultracold polar molecules
Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]). In these states, particles occupy the same quantum state and exhibit interesting
Could quantum physics help us find Earth 2.0?
When astronomers talk about directly imaging an exoplanet orbiting a faraway star, the analogy they most commonly use is trying to spot a firefly next to a massive searchlight. An Earth-like exoplanet is incredibly dim—usually between 100 million and 10 billion times fainter
