Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those
Regions with greater socioeconomic inequalities are more affected by cold weather, whereas areas with higher levels of wealth and urbanization are at greater risk during heat waves and lower risk during cold spells. This is shown by a study led by the Barcelona Institute for
Malaysia is resorting to cloud seeding to bring much-needed rain to the country's "rice bowl" north, where a drought has delayed planting of the staple crop and raised supply fears.
The European Union's climate monitor said Friday that ocean temperatures are edging toward record highs as conditions shift toward a potentially powerful El Niño weather pattern.
Scientists may have uncovered a surprising secret behind why life exists at all. A new study suggests that the Universe’s fundamental constants — the deep physical rules that govern everything from atoms to stars — appear to sit within an incredibly narrow “sweet spot” that
A mysterious comet from beyond our solar system is giving astronomers a rare glimpse into alien worlds — and it may have formed in a place far colder and stranger than anything around our Sun. The interstellar visitor, called 3I/ATLAS, contains an astonishingly high amount of
The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated smashups inside

A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells,
The question sounds simple. The answer, once you examine the actual measurement science behind it, is more interesting than either "yes" or "no."
A new computational method could dramatically accelerate efforts to map the body's cells in space, according to a study published in Nature Genetics. Spatial multi-omics technologies—often described as ultra-high-resolution maps of tissues—allow scientists to see not only which
Satellite images, weather maps and other data are collected in enormous quantities—but much of this remains unused. The reason is simple: the data is fragmented, difficult to interpret, and stored in different formats. Dr. Arka Ghosh has developed a system capable of
Garlic is not a substance that most people consider an aphrodisiac. It turns out that mosquitoes agree. In fact, a new Yale study finds that garlic also functions as a de facto birth control for mosquitoes and other winged insects, an insight that could lead to eco-friendly
For decades, the common explanation for why children struggle to read has stayed remarkably consistent. Smart kids read well. Kids who don't simply aren't smart enough. And when children strain over a page, the assumption has often been that something about how they see the
Forming social connections online and via social media reduces how much people engage with and learn from the content posted but significantly boosts their networking performance, according to new research. The study, published in Journal of Experimental Social Psychology, led
University of Birmingham researchers have demonstrated a new method to break down toxic pollutants in wastewater, using sunlight and molecular-thin catalysts created using an innovative "mechanical" approach. Non-degradable dyes originating from industries such as textiles,
Eating eggs might do more than just start your day—it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27%
Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding contamination in the food supply. The work is published
When most people think about biodiversity in lakes and rivers, they imagine fish, plants, or perhaps birds and amphibians. But beneath the surface exists another world that often goes unnoticed: microscopic parasites that quietly shape aquatic ecosystems in ways scientists are
With over 60,000 ships passing through the Strait of Gibraltar each year, this stretch between the Atlantic and Mediterranean is one of the busiest waterways on the planet. This narrow strip of water is also home to a critically endangered population of long-finned pilot whales
