How this odd-looking animal outsmarted aging
Naked mole-rats seem to have found nature’s cheat code for longevity. Scientists discovered that small tweaks in one of their proteins make it better at fixing DNA damage, helping the animals resist aging. Even fruit flies with the same changes lived longer, hinting at a
A once-in-a-generation discovery is transforming a Michigan dairy farm
At first glance, the 400 acres of soybeans growing on the Preston family's dairy farm in southern Michigan looks like a typical field. But these aren't ordinary soybeans. They represent a breakthrough partnership with Michigan State University that's saving the family tens of
Are cancer surgeries removing the body’s secret weapon against cancer?
Scientists have found that preserving lymph nodes during cancer surgery could dramatically improve how patients respond to immunotherapy. The research shows that lymph nodes are essential for training and sustaining cancer-fighting T cells. Removing them may unintentionally
85 years of big tree history available in one place for the first time
Whether strolling through the woods or taking a rest from outdoor labor, autumn is a time when people contemplate the value of our trees and forests. The curious can now also explore the historical documents of the nation's biggest trees dating back to the 1940s online, in one

Hybrid metasurface modulates light at low voltages for energy-efficient optics
Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to develop a wide range of advanced technologies, including optical photonic,
Microscopic DNA 'flowers' could deliver medicine exactly where it's needed
Researchers at the University of North Carolina have created microscopic soft robots shaped like flowers that can change shape and behavior in response to their surroundings, just like living organisms do. These tiny "DNA flowers" are made from special crystals formed by
2D devices have hidden cavities that can modify electronic behavior
In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists
Neanderthal-human hybrids may have been scourged by a genetic mismatch
When Homo sapiens and Neanderthals interbred, a genetic variation affecting red blood cells may have hindered reproduction in women who were hybrids, and this might have played a part in Neanderthals’ demise
Scientists reveal the best exercise to ease knee arthritis pain
A sweeping review of over 200 studies finds that aerobic exercises like walking and cycling offer the best pain relief and mobility gains for knee osteoarthritis. Compared to other types of exercise, aerobic training showed the strongest evidence across short- and long-term
Flood reckoning for Bali on overdevelopment, waste
Standing where her family home once was, Ruth Deidree Boelan closed her eyes and prayed for relatives missing in devastating flash floods that swept resort island Bali this year.
Toxic haze chokes Indian capital
India's capital New Delhi was shrouded in a thick, toxic haze on Monday as air pollution levels soared to more than 16 times the World Health Organization's recommended daily maximum.
Invisible poison: Airborne mercury from gold mining is contaminating African food crops, study warns
In a recent study published in the journal Biogeosciences, scientists have confirmed that mercury pollution from artisanal and small-scale gold mining (ASGM) is contaminating food crops not through the soil, as previously believed, but directly from the air. Driven by the
Your DNA may shape how you use cannabis
A major collaboration between UC San Diego and 23andMe identified genes that shape cannabis use behaviors. The study linked the CADM2 and GRM3 genes to cannabis use and connected these patterns to more than 100 traits across mental and physical health. Researchers say
This new iron supplement heals anemia without hurting your gut
Researchers have created a new iron supplement that merges iron, probiotics, and prebiotics. This “three-in-one” formula restores iron levels while maintaining gut health and preventing inflammation. In mice studies, it normalized hemoglobin and gut bacteria without side
The hidden evolution making men’s sperm more dangerous with age
Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed dozens of genes under selective pressure, many linked to serious disorders. The
Glowing sugars show how microbes eat the ocean's carbon
Researchers have developed a light-emitting sugar probe that exposes how marine microbes break down complex carbohydrates. The innovative fluorescent tool allows scientists to visualize when and where sugars are degraded in the ocean. This breakthrough helps map microbial
Marriage is hard, but it's even harder when you immigrate together
Canadian immigration policy has long emphasized family reunification. In fact, most of Canada's 200,000 yearly newcomers migrate as a couple or a family unit.
As a glacier retreats, a gold mine advances. Why are some locals angry?
A small Canadian mining company, Canagold, is seeking permits and approvals to renew gold mining operations at a remote site in northwestern British Columbia (B.C.). Called the New Polaris Mine, it faces opposition from First Nations, environmental nonprofits and downstream
World's carbon dioxide levels hit a record high in 2024: Report
Carbon dioxide (CO2) levels in the atmosphere soared by a record amount to new highs in 2024, committing the planet to more long-term temperature increase, according to a new report from the World Meteorological Organization (WMO).
This powerful drug combo cuts prostate cancer deaths by 40%
A new drug combo of enzalutamide and hormone therapy has been shown to extend survival for men with recurring prostate cancer, reducing death risk by over 40%. The study followed more than 1,000 patients worldwide and was led by Cedars-Sinai researchers. Experts call it a game
Cancer patients who got a COVID vaccine lived much longer
A groundbreaking study reveals that cancer patients who received a COVID-19 mRNA vaccine within 100 days of starting immunotherapy lived dramatically longer than those who didn’t. Researchers from the University of Florida and MD Anderson Cancer Center discovered that the
Astronomers discover a gigantic bridge of gas connecting two galaxies
Researchers from The University of Western Australia node at the International Centre for Radio Astronomy Research (ICRAR) have uncovered a colossal bridge of neutral hydrogen gas linking two dwarf galaxies, which spans an astonishing 185,000 light-years between galaxies NGC
A clue to ancient life? What scientists found inside Mars’ frozen vortex
Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture lets ozone build up unchecked. This discovery, made with data from ESA’s and
Clocking into the internal rhythm of wheat plants
Circadian clocks of wheat can provide a window into the plant's nutrient content and life cycle, finds new research that could improve agricultural production and crop resilience in a changing climate.
