The Sloan Digital Sky Survey (SDSS), the largest multispectral imaging and spectroscopic redshift survey of the cosmos, has released its 20th data release (DR 20). It is also the third release of the survey's fifth phase (SDSS-V), representing a massive operational expansion of
Superconductors are materials that conduct electricity without electrical resistance when cooled below a specific critical temperature. These materials have proved promising for the development of various technologies, including medical imaging instruments, particle
War destroys laboratories and instruments. It also severs the human networks through which science reproduces itself. It disrupts mentorship, collaborations and informal ties that turn students into researchers.
Toiling around the clock, haggard Indonesian firefighters on the island of Borneo cannot keep up with the blazes devouring landscapes and shrouding communities in a cloying haze.
When rescue dog Chloe is not tumbling across the grass on a farm outside India's tech capital, Bengaluru, she is learning to sniff human breath for cancer with a little help from AI.
About 1 million young people in the UK are not in education, employment or training (NEET). The consequences for their health and income can be significant and long-lasting, with costs to the economy as well.
A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease. These cells, known as peripheral blood mononuclear cells (PBMCs), are widely used to study infections, autoimmune disorders, cancer and the immune
A large study involving more than 270,000 people has linked higher blood levels of the amino acid tyrosine to a shorter lifespan in men. Using both observational data and genetic analysis, researchers found that elevated tyrosine could potentially reduce male life expectancy by
While the highly virulent avian influenza strain has only recently been discovered on Australian shores, researchers at Deakin University have been working behind the scenes for years, anticipating what an outbreak might look like.
Researchers have mapped breast tumors in striking detail and uncovered hidden pockets of dormant cancer cells that may help explain why cancer can return after treatment. Unlike rapidly dividing cells, these quiet cells can essentially hibernate, allowing them to evade
Certain chemical substances, broadly called luminogens, have an inherent ability to emit light. Most fluorescent molecules emit light in solution but lose their emission in the solid state, where the molecules aggregate.
Older adults at risk of dementia improved their memory and thinking after following lifestyle programs combining exercise, healthy eating, cognitive training, and social engagement. Those who received regular coaching and structured support improved substantially more than
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study published in the journal JGR Solid Earth, a group of
Sorbitol, a sugar alcohol commonly used in sugar-free candy, gum, and other low-calorie foods, may not be as harmless as it seems. Researchers at Washington University in St. Louis found that the body can convert sorbitol into a form of fructose in the liver, potentially
With their slender bodies and long front legs, Miracinonyx trumani—often nicknamed the "American cheetah"—was long thought to be a North American analog of the African big cat. But in a new study published in the journal Current Biology, researchers reveal that the extinct cat
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, as scientists have created one of the longest
The Pantone color of the year for 2026 is white. It's called Cloud Dancer, which is described as a "lofty white." This choice reflects a growing trend away from color in our visual world.
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. The three glitches included one that changed its
Autocracy wasn’t inevitable in early civilizations. But when riches were there to monopolize, strongmen and inequalities emerged
Several space missions are searching for extraterrestrial life, which could come in the form of microbes The post Many Space Missions Are Searching for Life Beyond Earth—But Are We Prepared for the Fallout If They Succeed? appeared first on Nautilus .
