NASA’s Roman Telescope Will Spot Distant Black Holes That Shred Stars

Lee esta nota de prensa en español aquí. How do black holes at the center of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances, which existed much earlier in the universe’s history. New research suggests NASA’s Nancy Grace Roman Space Telescope, which […]

Eating chili peppers may raise the risk of one deadly cancer

A major review found that people who consumed the most chili peppers had a substantially higher risk of esophageal cancer, though the evidence was less clear for stomach and colorectal cancers. Researchers emphasize that the findings show an association, not proof of cause and effect, and that more research is needed to determine whether moderate consumption carries similar risks.

Are there aliens on exoplanet K2-18b? Scientists just scanned it for signals

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced software analyzed millions of signals, filtering out Earth-based interference and other false positives. No convincing artificial radio transmissions were found, but the project demonstrated a powerful new approach that will make future SETI searches faster and far more effective.

A 37-year soil experiment revealed a hidden climate threat

The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely protected. That releases extra carbon dioxide into the atmosphere, potentially accelerating global warming.

Can humans hibernate their way to Mars?

Scientists are trying to recreate the biology that lets animals survive months without food or water, in hopes of making deep-space travel possibleLong-term space travel is bad for your health. Very bad. Being in space exposes humans to dangerously high levels of radiation; extended exposure to microgravity can damage a range of organ systems, including muscles, bones and eyes. Living for months or years in tight quarters can have severe psychological effects.The key to solving these problems co

Popular weight-loss drugs Ozempic and Wegovy may slow biological aging

Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging. Although the findings are encouraging, scientists say larger studies are needed before concluding that the medication can help people age more slowly.

Heat can be deadly, but sunshine itself? Science says we could use more of it | Rowan Jacobsen

Extreme exposure should be avoided, but we’ve gone too far the other way – enjoyed safely, the sun can have enormous health benefitsHigh summer has returned to the UK, and with it, the usual warnings about the dangers of sunlight and reminders to seek shade and cover up. After years of such advice, most members of the public naturally assume that the science connecting sun exposure to poor health is well established, so people are often shocked to learn that the opposite is true: those who spend

This dinosaur fossil captures the final moments of a T. rex attack

A fossilized Edmontosaurus skull with a Tyrannosaurus tooth still embedded in its face has given scientists rare evidence of a dramatic predator-prey encounter. The discovery suggests the giant carnivore delivered an incredibly powerful face-to-face bite, offering new clues about how Tyrannosaurus hunted.

Giving nature a say: why Scottish marine scientists appointed the ocean to their board

As the rights of nature are increasingly being recognised, the Scottish Association for Marine Science is the latest organisation to make the ocean a trusteeIn a boardroom in an office building in Oban, a picturesque town on the west coast of Scotland, trustees attending meetings have long been able to see the breaking waves of the Atlantic through the windows. But since last month, the ocean has also been present in the room, with an unusual new initiative ensuring that it now has a say on deci

NASA's Perseverance just completed a marathon on Mars

NASA's Perseverance rover has reached an impressive new milestone on Mars, completing the equivalent of a full marathon by driving 26.2 miles (42.195 kilometers) across the Red Planet. It accomplished the feat in just five years and four months, reaching the distance on its 1,890th Martian day, less than half the time it took the previous record holder, NASA's Opportunity rover.

NASA selects four new Moon missions to build a permanent lunar base

NASA is ramping up its lunar ambitions by awarding nearly $600 million for four commercial Moon landings planned for late 2028. Each mission will carry the same trio of science instruments to improve lunar navigation, study dangerous dust kicked up during landings, and map the Moon's radiation environment. The agency also revealed plans for new rovers, communication satellites, and additional cargo missions as it lays the groundwork for a permanent Moon Base.

Fungi: the invisible force protecting our planet – podcast

Scientists often talk about the importance of flora and fauna to the health of our planet, but Dr Toby Kiers, an evolutionary biologist and founder of the Society for the Protection of Underground Networks, wants us to consider another force: fungi.

Alan Turing's biggest AI assumption may have been wrong

A new book claims AI has been built on a flawed assumption dating back to Alan Turing's famous 1950 paper. Peter J. Denning argues that the most important parts of human intelligence, including common sense, intuition, culture, and practical know-how, cannot be encoded into computers. He believes this makes true human-level AI impossible, regardless of how large language models become.

New dark matter theory could solve multiple cosmic mysteries at once

Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward. This simple idea could explain several puzzling cosmic observations that have frustrated astronomers for years, from unusually diffuse dwarf galaxies to surprisingly dense dark matter clumps that bend light through gr
