Ukrainian media coverage casts land as both lifeline and danger zone
An international team led by Alexander Vorbrugg analyzed (online) media reporting on war-related land changes in Ukraine. The study asked: How is damage to land represented? What knowledge do these representations draw on? How does the war affect the symbolic meaning of land
Ultrafast light can control ferromagnetism without relying on heating
Despite being known for more mundane uses such as sticking notes to refrigerators or keeping bags shut, magnetization is one of the most fundamental and useful properties of a material. Indeed, it forms the physical basis for storing most of our digital information, encoding
Better data analysis links to stronger marketing and innovation in Thai retail sector
A study of 500 Thai retailers has found that businesses with stronger big data analytics capabilities tend to be better at identifying market needs, innovating and executing effective marketing strategies. Moreover, large retailers report higher capability levels than smaller
When a few people break the rules, bad behavior spreads quickly
The old saying that one bad apple spoils the barrel suggests that an individual behaving badly can have a negative influence on the entire group. The idea now has some fresh scientific backing.
Methane emissions in Baltimore show seasonal, daily trends
Natural gas leaks are a significant source of methane emissions in cities, but it can be hard to pinpoint exactly where and why they happen. And methane, a potent greenhouse gas that is the main chemical component of natural gas, has been historically undercounted or omitted in

Poor ocean conditions leave murrelet chicks exposed to nest predators for longer
Less favorable ocean conditions mean marbled murrelet chicks take longer to leave the nest, making them more vulnerable to predation, according to a new study of the Pacific Northwest seabird by Oregon State University scientists.
Childhood experiences of war loom large over CEOs' decision-making
The trauma of war has long-lasting reverberations, influencing business decisions made decades later, argue Eun Hye Jo and Jenny Jung-Wha Lee, accounting professors at Costello College of Business based at George Mason University Korea.
Two-in-one tool tracks viral RNA inside live infected cells in real time
Viruses are sneaky intruders, hijacking the internal machinery of host cells and replicating out of sight. Understanding these dynamics is the first step to developing effective antiviral strategies that could stop infections, but scientists have largely been left in the dark

AI could turn scientific papers into research assistants
An AI ‘virtual author’ can help scientists use a paper’s methods on new data. But it’s not going to match a human author’s expertise.
Africa's bats could survive climate change—if they can find somewhere to live
Climate change and changes in the way land is used are the two biggest threats to wildlife because they change the environment in which animals survive and thrive. Knowing how species respond to these pressures is central to planning conservation actions.
Reindeer grazing changes plant roots in pine forests
Reindeer grazing changes the vegetation of northern pine forests below ground as well as above it. In a recent study in Finland, trees and understory vegetation in grazed forests had nearly 30% less shallow-root biomass than those in ungrazed areas. Root structure also changed,
Reexamined Viking 2 signal reveals possible marsquake from region active decades later
Earthquakes and the seismic waves they generate provide some of the best clues to Earth's interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking Mars landers, which reached Mars in 1976. Though the
Super Typhoon Champi sets the record for strongest storm of 2026
The cyclone’s winds hit 185 miles per hour—the strongest windspeed of any storm this year
How life on Earth experiences climate change
Climate change can look very different at the scale of a forest, field or hillside. A new review shows how changes in vegetation and atmospheric conditions can cause local microclimates to warm at very different rates from the regional climate—and why this matters for
Migratory birds spread avian influenza to Greenland's polar bears
Migrating birds that breed in the Arctic are spreading avian influenza to polar bears in eastern Greenland, according to a new study that found evidence of infections in bear blood samples acquired from Greenland Inuit subsistence hunters.
Light-based method could offer first way to detect hypothetical 'mirror life'
Scientists have proposed what they believe is the first method for detecting "mirror life"—a hypothetical form of life made from molecular building blocks that are the mirror image of those found naturally on Earth. Researchers at the University of Strathclyde and the
South Korea guides crowd-pulling shark out of canal
A shark that has become a viral sensation in South Korea was coaxed out of a canal in which it was stuck, authorities said on Wednesday, as falling temperatures raised concerns for its survival.

Mirror-image molecules are difficult to separate from their counterparts, but a new catalytic method might be the answer
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team of researchers in Japan might have found a solution.
'Invisible' tweak could help make protein shakes less clumpy
Scientists from RMIT University and Riga Technical University in Latvia have shown that static charge left on surfaces can be controlled, which may have big benefits for companies needing to avoid the little zap in production of common household goods. The discovery could even
'The fishing's terrible': Deforestation devastates Central African river
Sitting in his narrow dugout canoe, Jean-Romeo Senguemboli frowned at the meager catch in his nets on the Central African Republic's Mbali River, where experts say deforestation is devastating the fish population.
A lifesaving medication is not behind the drop in U.S. overdose deaths
A possible reason for the overdose deaths drop is more use of naloxone, which reverses opioid overdoses. But while still a key tool, its use fell too.
Report pinpoints future exploration sites on the moon
Besides building crewed outposts at the lunar south pole, where else should astronauts go on the moon? An authoritative new report has suggestions
UN projections say world is losing ground in fight to curb climate change, faulting US a bit
Losing more ground in the fight against climate change, humanity is heading for a hotter world than experts projected last year—and the United States is a big reason for that, a new United Nations report says.
Bending a liquid: Liquid membranes flex 100 times more easily than cell membranes
Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for membraneless compartments inside cells and for
Arrival of the Suebi, Alans and Visigoths did not erase deep genetic legacy of Roman Hispania
An international study led by the Institute of Evolutionary Biology (IBE, CSIC-UPF) in Barcelona, the Natural Sciences Museum of Barcelona, Harvard University and the University of the Basque Country (EHU) has reconstructed the genetic history of the Iberian Peninsula between
Newly identified metabolic pathway helps explain how cold extends lifespan
Moderately cold temperatures have proven to effectively extend lifespan and delay age-related decline in animals. However, how cold temperatures trigger these beneficial effects at the molecular level has remained largely unclear.
Scientists reveal how deadly Andes hantavirus attaches to human cells
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. In a study published in Nature, scientists at Albert Einstein College of Medicine and
