Earth is reflecting less sunlight, and absorbing more heat, than it did several decades ago. Global warming is advancing faster than climate models predicted, with observed temperatures exceeding projections in 2023 and 2024. These trends have scientists scrambling to
People need to feel that climate change is affecting them now or that taking action is a patriotic act for their country to overcome apathy toward environmental efforts, a new global study has found.
Tropical countries from Cameroon to Colombia could earn tens of millions of dollars a year under a novel approach to protecting the world's rainforests being launched at the COP30 summit in Brazil.
A suspected strike by "tiny space debris" has delayed the return of the Chinese spaceship Shenzhou-20 and three astronauts, Beijing's space agency said on Wednesday.

New Zealand is planning a national space mission which could see a small fleet of state-owned satellites launched into the skies over the Pacific nation, a minister told AFP on Wednesday.
India is the world's most populous country, the third-biggest emitter of greenhouse gases, and remains deeply dependent on polluting coal to meet soaring energy demand.
Engineers at the University of Delaware have uncovered a way to bridge magnetism and electricity through magnons—tiny waves that carry information without electrical current. These magnetic waves can generate measurable electric signals within antiferromagnetic materials,
The European Union's member states have not yet reached an agreement on key emissions targets before the UN's COP30 summit in Brazil, and ministers will meet again on Wednesday to thrash out a deal, according to Brussels officials.
A satellite imagery analysis shows that the 2021 "heat dome" scorched almost 5% of the forested area in western Oregon and western Washington, turning foliage in canopies from a healthy green to red or orange, sometimes within a matter of hours.
Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long thought to come from pulsars. The findings revive dark matter as a major
Initiatives on the table at COP30 aim to evaluate which countries are most vulnerable, support efforts to clean up industries and pay for the protection of tropical forests
Most offices have that one worker who has problems controlling their indoor voice. Either too loud or too soft, it can be distracting to colleagues—especially as workplaces become increasingly open concept, with fewer closed offices to ensure privacy and quiet.
Hops are an essential ingredient in beer brewing and an important economic crop. The female flowers of hops are covered in tiny glandular trichomes that synthesize and store a variety of specialized metabolites, collectively defining the flavor and quality of beer. Terpenes
As the world approaches critical tipping points, a comprehensive global scientific report shows that resilience—the ability to live and develop with change and crises—must now be placed at the heart of global decision-making.
Cockroach infestations don’t just bring creepy crawlers, they fill homes with allergens and bacterial toxins that can trigger asthma and allergies. NC State researchers found that larger infestations meant higher toxin levels, especially from female roaches. When extermination
Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people — and one strain moves as fast as swine flu. Using genomic data from the UK and Norway, scientists modeled bacterial transmission rates and discovered key differences between
Scientists at Mizzou have identified two small molecules, agmatine and thiamine, that could both reveal and fight glaucoma. Their research shows these compounds are lower in glaucoma patients, suggesting they may serve as early warning markers. Even better, they might help
In our modern society, aging tends to be something we ignore, and then try to avoid. Mainstream culture is geared toward the young, using the young to gauge trends and styles, and targeting their spending power. Meanwhile, the anti-aging industry is booming, with billions of
