Physical surroundings affect everything from personal well-being to a neighborhood's safety. A new study from The Ohio State University finds that when it comes to preventing gun violence in a community, green space can help, but its location makes a big difference.

Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts that a rotating object, such as Earth, slightly drags the surrounding spacetime as it rotates, a phenomenon known as frame-dragging.

Countries highly vulnerable to the phase-out of oil, gas and coal account for just 6% of global economic output, countries in Africa stand to benefit from their vast solar energy potential, and the economic interests of the U.S., Europe and China are affected by climate policy in surprisingly similar ways. A study by the Potsdam Institute for Climate Impact Research (PIK) published in Nature Sustainability now shows, for 169 countries around the world, how the fight against global heating affects national assets—and what geopolitical challenges and opportunities arise as a result.

New research has revealed an unexpected new mechanism through which the killer fungus Candida auris is resisting antifungal drug treatment. A team led by the University of Exeter and City St George's, University of London, discovered that the fungus creates multiple versions of its entire genome, including mutating a gene that plays a role in cell wall integrity, called "Crazy-one" (CRZ1).

In the middle of nowhere, a small island emerges in the Atlantic Ocean. This unique territory completely changed in the 19th century thanks to the efforts of two British scientists: Charles Darwin and Joseph Dalton Hooker, researchers who stopped at the British naval base and documented the island during their expeditions.

Consumers may not fully understand precision fermentation yet, but many are curious enough to taste the results. New qualitative research from the EIT Food Consumer Observatory, published ahead of World Food Day on Oct. 16, suggests that this curiosity creates an important opportunity for food innovation, provided companies can answer consumers' questions clearly and deliver on the first bite.

A new report by CSIRO, Australia's national science agency, has found a growing suite of promising options already available to reduce on-farm emissions, as well as further opportunities for practical solutions for Australian producers.

Across the waters of West Africa, commercial fishing vessels vanish along international boundary lines.

The only lizard in the world that can live and forage at sea may now be in a fight for survival. International scientists warn black-market trafficking of Galapagos marine iguanas is peaking just as the super El Niño decimates their natural food source.

By 2025, 143 of 154 developing countries had a National Adaptation Plan process in place, yet implementation has not kept pace. Many countries still lack the institutional capacity, project preparation and finance needed to turn their priorities into strategies, bankable projects and results on the ground.

Artificial intelligence is increasingly being used by social service agencies to handle cases involving child abuse, intimate partner violence and elder abuse. But a University of Iowa researcher and former social worker says the agencies need to establish safeguards to ensure that AI technology does not lead to bias against vulnerable or disadvantaged populations.

Tourists who care deeply about sustainability are not necessarily willing to pay extra to reduce the environmental impact of their vacations, according to new research from the University of Portsmouth.

Nepal's disaster authority said Wednesday that an avalanche of rock and ice triggered a recent flash flood, echoing the mountain collapse that unleashed a tsunami-like wall of water in August.

What should you cook for dinner on a budget of 20 euros when you have a guest with a gluten intolerance? A shopper might ask a shop assistant for advice or consult, for example, Hopla, the AI-powered shopping assistant launched by French supermarket chain Carrefour. Behind this everyday choice lies a broader question: when faced with a recommendation, who do we trust more? A human being or an AI?

The transition to a low-carbon economy will not affect all people and places equally. Although its overall benefits may outweigh its costs, workers may lose jobs, households may face higher prices and communities dependent on carbon-intensive industries may experience lasting economic and social disruption.

University of Warwick astronomers have shown that white dwarf stars can glow in a range of colors, including the first star ever found that would appear green to the human eye.

Publishing scientific articles requires more than knowledge of academic writing conventions; it also depends on access to networks that support the research and publication process. Academic networks provide opportunities to exchange knowledge, receive feedback and develop collaborations that can strengthen both research and careers. For researchers in vulnerable situations, such connections can be crucial.

Agriculture in the Global South remains under pressure to produce more food while responding to climate change and resource constraints. Policy responses have focused on increasing production. But what about postharvest losses? Globally, about one-third of food produced for human consumption is estimated to be lost or wasted.

If you've ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That's why NASA researchers are working to develop a battery that could function in the brutal cold of the moon's south pole, where nighttime temperatures plunge to minus 328 degrees Fahrenheit (minus 200 degrees Celsius).

Busoga, in eastern Uganda, is a low, fertile plateau surrounded on three sides by Lake Victoria, the Nile River and Lake Kyoga. Most of its 4.3 million people farm small, rain-fed plots. Yet hunger is common: in the 2024 census, about a third of Busoga households reported going whole days without food.
