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 .
Collectively intelligent bricks figure out if they’re in a boat, chair or guitar
Germany's Isar Aerospace launched a rocket into orbit from Norway on Saturday as Europe races to boost its ability to economically send satellites into space independently of the United States.
Indonesia’s dangerous peat fires are surging early in the 2026 fire season as a strengthening El Niño and severe drought dry out wetlands that can burn underground for months. These slow smoldering fires are especially destructive because they release far more fine particles
Acrid smoke hung heavily over the Malaysian town of Serian, seeping into homes and cloaking roadside stalls, as residents navigated an air-quality emergency fueled by transboundary haze from Indonesia's raging fires.
Princeton researchers have tested an AI system that can monitor and control fusion plasma in milliseconds, reacting far faster than a human operator. In one experiment, it predicted a damaging instability about 200 milliseconds before it appeared and adjusted the plasma to stop
Researchers may have found a new way to weaken glioblastoma’s defenses against treatment. Blocking a protein called SET prevented tumors from forming in preclinical models, while targeting related proteins made cancer cells more vulnerable to radiation. The strategy works by
Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for some of the lightest proposed forms of dark matter. The approach dramatically improved limits on ultralight axions and uncovered several intriguing dark photon signals that still need
Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The discovery suggests sophisticated
Heart disease and chronic kidney disease can accelerate one another, but new guidelines say simple screening and early treatment could substantially reduce the risks. Blood and urine tests, combined with proven heart and kidney therapies, may help catch problems sooner and
A common frog found across Ecuador and Colombia has finally been recognized as its own species after more than a century of mistaken identity. Museum specimens from the 1800s helped scientists reveal that Pristimantis milpe had been hiding in plain sight all along.
Scientists have found evidence that vulnerability to rheumatoid arthritis may begin before birth. Finger joints commonly affected by the disease develop with different tissue structures and larger populations of specialized fibroblasts than joints that are usually spared. Those
