Researchers who examined Canadian child welfare data found that Black children were not only investigated at a higher rate than their white peers but were also more likely to be taken from their homes, even when the only difference between cases was the child's race. [...]
A smaller white dwarf star (left) pulls material from a larger star into a swirling accretion disk in this artist's concept released Nov. 19, 2025, to illustrate the first use of NASA's IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star. [...]
A tiny beetle responsible for killing hundreds of thousands of oak trees in Southern California has reached Ventura County, marking a troubling expansion. [...]
Happiness and well-being depend on how much volition, choice and control people feel they have over their life—their sense of autonomy. Researchers have acknowledged this connection, but there's been disagreement about whether it's universal or simply a reflection of the situation in wealthier, more individualistic countries. Understanding this nuance would help policymakers focus efforts to boost well-being where they matter most. [...]
Aboard an aluminum skiff or one of her five kayaks, fourth-generation shrimper and fisherwoman Diane Wilson often plies the coastal bays and streams near her tiny hometown of Seadrift, Texas. [...]
Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what the mechanisms, or the causes behind those specific genetic changes, are. Recent studies using fission yeast, which can act as an ideal model for human cells, have highlighted one possible mechanism linked to disease onset. [...]
Heat-resilient biofertilizers could help crops cope with rising temperatures but engineering them has been slow and uncertain. A new study at the National Institutes for Quantum Science and Technology (QST) shows that pairing experimental evolution with controlled gamma-ray mutagenesis can accelerate the path to heat-tolerant nitrogen-fixing bacteria, shortening development timelines and opening practical routes to more reliable, climate-ready microbial products for agriculture, food processing, pharmaceuticals, and biofuel production. [...]
On Jan. 9, The Environmental Protection Agency determined Colorado cannot order the closure of coal-fired power plants under the Clean Air Act, and, therefore, the agency will deny the state's plan to reduce the haze that clouds views at Rocky Mountain National Park and other federal lands. [...]
Today, trans people face politicization of their lives and vilification from politicians, media and parts of broader society. [...]
Water extremes such as droughts and floods have a huge impact on communities, ecosystems, and economies. Researchers with The University of Texas at Austin have turned their attention to tracking these extremes across Earth and have discovered what is driving them. [...]
A new Stanford-led analysis of corporate carbon disclosures finds that companies undercount emissions from their supply chains by billions of tons. [...]
For decades, the United Nations' Intergovernmental Panel on Climate Change (IPCC) has offered a snapshot of the planet's changing climate—but University of Toronto researchers have found that some of the underlying data underrepresents a key driver of Arctic warming. [...]
As the climate changes, scientists are concerned about how well plants and animals will adapt to rapid warming. A new University of Vermont study has explored the early embryonic life stage of a globally common fruit fly, Drosophila melanogaster, looking at how the eggs responded to temperature variability at the genomic level. [...]
Mitochondrial dysfunction is associated with various chronic diseases and cancers, including neurodegenerative diseases and metabolic syndrome. Gently extracting a single mitochondrion from within a living cell—without causing damage and without the guidance of fluorescent makers—has long been a challenge akin to threading a needle in a storm for scientists. [...]
Whether they are laundry detergents, mascara, or Christmas chocolate, many everyday products contain fatty acids from palm oil or coconut oil. However, the extraction of these raw materials is associated with massive environmental issues: Rainforests are cleared, habitats for endangered species are destroyed, and traditional farmers lose their livelihoods. [...]
Cereals have natural resistance to pathogenic fungi, but powdery mildew, for example, can overcome this resistance. A team at the University of Zurich has now discovered a new mechanism that enables powdery mildew to outsmart the immune system of wheat. This opens the door to targeted development of resistant varieties with a reduced risk of resistance breakthrough. [...]
"The UN estimates that by 2050, common bacterial infections could kill more people than cancer," says Arnold Mathijssen, a biophysicist at the University of Pennsylvania who studies how active particles like bacteria move in fluidic systems. "Bacteria are remarkably fast, adaptive swimmers, capable of moving hundreds of body lengths per second while being subjected to strong fluid flows." [...]
McGill engineering researchers have introduced an open-source model that makes it easier for experts and non-experts alike to evaluate greenhouse gas emissions from U.S. natural gas supply chains and yields more accurate results. [...]
By fine-tuning the surroundings of single cobalt atoms, researchers reveal how tiny design changes can steer oxygen reactions toward cleaner and more efficient hydrogen peroxide production. [...]
We know the genes, but not their functions—to resolve this long-standing bottleneck in microbial research, a joint research team has proposed a cutting-edge research strategy that leverages artificial intelligence (AI) to drastically accelerate the discovery of microbial gene functions. [...]
At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the extent to which Mars is quietly tugging on Earth's orbit and shaping the cycles that drive long-term climate patterns here, including ice ages. [...]
Newly published interdisciplinary research led by the University of Tennessee, Knoxville, and University of Maryland shows that viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water. [...]
An international team of researchers has uncovered hidden clues about life in the hills of ancient southwest Samos, Greece. [...]
Plastic is everywhere in modern society. While it has paved the way for enormous progress, the pollution it leaves behind is now creating major challenges. [...]
For decades, researchers have focused on the problem of overgrazing, in which expanding herds of cattle and other livestock degrade grasslands, steppes and desert plains. But a new global study reveals that in large regions of the world, livestock numbers are substantially declining, not growing—a process the authors call destocking. [...]
The fault beneath Istanbul doesn't behave the way scientists once thought. [...]
This new NASA Hubble Space Telescope image captures a jet of gas from a forming star shooting across the dark expanse. The bright pink and green patches running diagonally through the image are HH 80/81, a pair of Herbig-Haro (HH) objects previously observed by Hubble in 1995. The patch to the upper left is part of HH 81, and the bottom streak is part of HH 80. [...]
A collaboration between Stuart Parkin's group at the Max Planck Institute of Microstructure Physics in Halle (Saale) and Claudia Felser's group at the Max Planck Institute for Chemical Physics of Solids in Dresden has realized a fundamentally new way to control quantum particles in solids. Writing in Nature, the researchers report the experimental demonstration of a chiral fermionic valve—a device that spatially separates quantum particles of opposite chirality using quantum geometry alone, without magnetic fields or magnetic materials. [...]
Multiple monkeys are on the loose in St. Louis, and AI-generated images are complicating the effort to find them. [...]
A new study by the University of Minnesota challenges previous classifications paleontologists use to determine how the fossil record is formed. They investigated how dinosaur and mammal bones are transported and buried by floodwaters to understand how the remains of animals might disperse prior to being buried and becoming fossils. [...]
