Rampant wildfires in the Americas drove a jump in global greenhouse gas emissions from fires in the year to February, new research found Thursday, warning that climate change was fanning the flames.
When the James Webb Space Telescope (JWST) began operations, one of its earliest surveys was of galaxies that existed during the very early universe. In December 2022, these observations revealed multiple objects that appeared as "little red dots" (LRDs), fueling speculation as
When we think of lead poisoning, most of us imagine modern human-made pollution, paint, old pipes, or exhaust fumes.
After Christmas dinner in 2021, our family was glued to the television, watching the nail-biting launch of NASA's US$10 billion (AU$15 billion) James Webb Space Telescope. There had not been such a leap forward in telescope technology since Hubble was launched in 1990.
Taking greater investment risks with technologies and new lines of business can help lower emissions from the aviation industry, one of the world's fastest-growing sources of climate pollution, according to new research from UCD Michael Smurfit Graduate Business School. The
Autonomy algorithms developed by researchers at the University of Toronto Institute for Aerospace Studies (UTIAS) could one day make cargo transport on the moon safer and more efficient for astronauts.
Weight-loss surgery dramatically outperformed GLP-1 medications in improving longevity and reducing heart, kidney, and eye complications for people with obesity and diabetes. Over 10 years, patients lost far more weight and required fewer medications. Experts say surgery
Stanford scientists have solved a long-standing challenge in growing brain organoids by using a simple food additive to keep them from sticking together. The breakthrough enables the production of thousands of identical mini-brains at once, making large-scale testing and
This week, researchers reported the discovery of four Late Bronze Age stone megastructures likely used for trapping herds of wild animals. Physicists have proven that a central law of thermodynamics does not apply to atomic-scale objects that are linked via quantum correlation.
The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c2), primordial black
Editor in Chief Nancy Shute explores the science behind major questions on food and health — from the addictive potential of ultraprocessed foods to the high-protein diet craze to the drawbacks of keto.
The most recent torrential rains in east-central Mexico, which have left at least 72 dead and dozens more missing, have raised questions again about the government's ability to alert people to severe weather in time.
Chinese Nobel Prize-winning physicist Chen Ning Yang, one of the most influential scientists in modern physics, died in Beijing on Saturday. He was 103.
A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. Scientists say these results
EMBL researchers created SDR-seq, a next-generation tool that decodes both DNA and RNA from the same cell. It finally opens access to non-coding regions, where most disease-associated genetic variants lie. By revealing how these variants affect gene activity, scientists can
A collaboration between the University of Michigan and AFRL has resulted in 3D-printed metamaterials that can block vibrations using complex geometries. Inspired by nature and theoretical physics, these “kagome tubes” demonstrate how geometry can yield properties that chemistry
Semaglutide, tirzepatide, and other GLP-1 drugs appear to slow alcohol absorption and blunt its intoxicating effects, according to new research. The study found participants on these medications felt less drunk despite consuming the same amount of alcohol. This could point to a
Quantum computers hold great potential for solving many problems more quickly or efficiently than conventional computers, but researchers are starting to identify where they could falter
How awe and wonder transform science and you The post More Than a Feeling appeared first on Nautilus .
One of the longest trials of artificial sweeteners to date found that they may increase beneficial gut bacteria, though the boost may also be related to weight loss
Many of the world's most important systems, such as the atmosphere, turbulent fluids, and even the motion of planets, behave unpredictably due to chaos and noise. Scientists often study these systems through their "invariant" measures, long-term statistical behaviors, rather
A team of researchers from the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, has developed a sensor that can identify sodium nitrite (NaNO2) in various beverages, including mineral water, orange juice, and wine. This inorganic salt is used as a
Negative interactions are impacting on conservation activities as they erode public support for endangered species, driving biodiversity loss.
