Acorns—not deer—can predict a rise in Lyme-spreading ticks
Despite deer’s essential role in tick reproduction, looking to acorn numbers instead can forecast Lyme disease booms almost two years in advance
Want to fly to the moon? NASA is looking for new astronauts to help grow its Artemis program
Want to fly to the moon and help build a permanent lunar base? NASA is accepting applications for a new astronaut class that will help grow the Artemis program.
Chimp sanctuary delivers an ape's food by drone amid Florida floods
A Florida chimpanzee sanctuary had to deliver food to one of its 200 apes by drone this week because the property was swamped by heavy rain. But the animals stayed safe, and the water finally was receding significantly on Saturday, the organization said.
A 24-hour fast triggers a surprising repair response in the gut
Scientists have discovered that fasting for just 24 hours increases a beneficial gut bacterium that helps the intestines regenerate after radiation damage. The preclinical findings could pave the way for new treatments that protect healthy tissue during cancer therapy,
MIT scientists turn immune cells into cancer killers inside the body
MIT scientists have developed nanoparticles that reprogram immune cells directly inside the body to attack cancer and harmful immune cells, eliminating tumors and reversing liver damage in mouse experiments. The breakthrough could make powerful immune therapies dramatically
A nuclear blast could save Earth from an asteroid, but there's a catch
A nuclear explosion might save Earth from a deadly asteroid, but new research suggests that hitting the wrong side could make the difference between success and disaster. Scientists found that an asteroid's irregular shape can dramatically affect how it responds to an X-ray
Low testosterone linked to 18% higher risk of dying from cancer
A major international study tracking more than 26,000 men found that very low testosterone levels were associated with an 18% higher risk of dying from cancer later in life. Surprisingly, testosterone itself showed no clear link to prostate cancer, although two other sex
Ancient Siberian tomb reveals surprising secrets of cannabis use 2,800 years ago
Scientists investigating a 2,800-year-old Siberian tomb discovered roughly 1,000 cannabis seeds and chemical evidence suggesting ancient Scythians used the plant for its intoxicating effects. The remarkable find, surrounded by evidence of elaborate burial rituals and animal
Scientists discover hidden brain changes linked to common sleep disorders
Scientists have discovered that sleep disorders are associated with structural changes in brain regions that control attention, decision-making, and emotions, potentially explaining why disrupted sleep can affect everyday thinking and behavior. The findings, drawn from 57 brain
Scientists squeeze record-breaking X-ray power into an incredibly tiny spot
Scientists have created record-breaking X-ray flashes lasting just 300 attoseconds, concentrating enormous power into an incredibly tiny spot. The breakthrough could unlock a new way to observe electrons in action and potentially control the ultrafast processes that drive
Stronger flu shot linked to nearly 55% lower Alzheimer's risk
A surprising new study suggests that a stronger flu shot could offer older adults significantly greater protection against Alzheimer's disease. Researchers at UTHealth Houston analyzed nearly 200,000 adults ages 65 and older and found that those who received a high-dose
Why the tropics lose the most birds when cities expand
Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics—known as the latitudinal diversity gradient—is pervasive across branches of the tree of life, and fossil evidence suggests it has
Scientists discover a hidden warning sign of cannabis addiction
A study of more than 17,700 US adults found that people who use cannabis in multiple forms have dramatically higher rates of daily consumption and addiction symptoms than those who stick primarily to one method. Nearly 67% of those who used almost every form met criteria for
Mysterious gas leaks suggest Mars may still be volcanically alive
Mysterious gas emissions and fresh volcanic fissures suggest that Mars may not be geologically dead after all, with hot magma potentially still active deep underground. The discovery could point to hidden pockets of warmth and chemical energy capable of supporting microbial
A hidden limit of space and time could unlock electronics 100,000 times faster
Scientists have discovered a surprising quantum limit that prevents electrons from being tracked with unlimited precision in both space and time. The breakthrough could pave the way for manipulating chemical reactions and developing electronics hundreds of thousands of times
Personalized savings reminders can help boost retirement savings
Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don't save, or you emphasize what they stand to gain if they do. To
NASA reveals new lunar rover, PROMISE, to launch to moon in 2028
At a press event on Saturday, the agency’s officials stressed that rovers and other infrastructure will be critical to ensuring human survival on the moon
Student finds proof of rare wild cat in northern New Mexico
Armed with dozens of motion-sensing cameras, William Grooms spent this past summer documenting wildlife across Carson National Forest in northern New Mexico. It was his first field season collecting photos for a two-year study to understand how forest structure influences
The hidden ways insects support animal life—from habitat to health—go way beyond being food
There are at least 14 million insect species on Earth, and they play highly diverse roles in sustaining the natural world. Insects provide many well-known benefits—what scientists often call "ecosystem services." For example, you can thank a bee or a hoverfly for pollinating
Different text genres help doctoral students adapt their writing to reach new readers
An academic abstract, a blog post and a public outreach article all place different demands on the writer. Readers' prior knowledge varies, as does the purpose of the text and what needs explaining. Mastering one kind of text therefore does not automatically mean being able to
Two paths, one flux: Trapped ions simulate Aharonov–Bohm interference in a lattice gauge theory
In a new Nature Physics study, researchers demonstrated the Aharonov-Bohm effect in a quantum simulation of a lattice gauge theory using a hybrid trapped-ion quantum computer.
Earth's gravity may have kept the early moon's volcanic heart beating
We typically think of the moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception. That understanding is grounded in physics—the moon should have cooled rapidly after forming when
Scientists discover new jellyfish species in waters off Alicante in Spain
The Mediterranean Sea still holds species unknown to science. One of them is Copula lucentia, a tiny jellyfish measuring just a few millimeters. Discovered off El Campello, in Alicante, it was formally described in 2024 by a research team at the University of Alicante (UA)
Heavy rain can more than double glacier speeds in Alaska
Glaciers are often thought of as unyielding blocks of ice that slowly carve out the landscape as they move downhill by gravity. But sometimes their slow crawl becomes a surge that sees them move orders of magnitude faster than their usual speed.
Earth’s Rocks Have a Missing Layer Spanning Up to a Billion Years
Now we finally know where it went The post Earth’s Rocks Have a Missing Layer Spanning Up to a Billion Years appeared first on Nautilus .
The introduction of a medieval public health system exposed the population to roundworm
Medieval health and sanitation efforts involved deliberate interventions; however, some of these measures had the opposite effect, leading to an increased spread of disease in Trondheim.
Theory predicting an older universe without dark matter or dark energy passes key cosmological tests
An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study. The research, titled "A Big Bang Nucleosynthesis Consistency Test
