Stay informed about scientific discoveries, research developments and new findings from around the world.
A catastrophic flood in Nepal that left thousands missing began with a collapse of ice and rock high in the mountains—a warning that disaster planning must prepare for chains of hazards, not isolated events, experts say.
Scientists have discovered that Mercury’s surface contains far less silicon dioxide than previously thought, pointing to an unexpectedly hot volcanic past. The finding suggests ancient lava may have originated from deeper, more extensively melted parts of the planet’s mantle.
The story of Dan Blumstein's decision to share videos of marmots from the Rocky Mountain Biological Laboratory field study on an OnlyFans account called OnlyMarms has captured attention around the world over the past few weeks.
Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers hope these genetic tricks could eventually reveal new ways to protect human health during aging.
Hydrogen (H2) evolution via photocatalytic water splitting is an environmentally friendly and sustainable technology for solar-to-chemical energy conversion. Although interfacial interactions are recognized as key determinants of photocatalytic performance, systematic experimental studies explicitly targeting the structure and reactivity of the water-catalyst interface remain limited. A major challenge lies in probing the molecular structure of interfacial water, especially under hydrogen-evolving conditions.
RhoBAST is a tiny RNA molecule that activates fluorescent dyes, enabling researchers to track RNA molecules in living cells with super-resolution. An international collaboration, which includes Ronald Micura and his team from the Institute of Organic Chemistry, has now shown that a small, local "nucleotide flip" within the RNA controls this fluorescence activation.
A feather discovered inside 66-million-year-old fossilized dinosaur poop may help explain why modern birds survived the asteroid catastrophe. The extinct bird it came from had more primitive insulating feathers, suggesting superior plumage may have helped the ancestors of living birds endure the deadly impact winter.
As our telescopes have improved and we've been able to peer farther back in time, we've begun finding more fascinating features of the universe. But one thing we haven't found for sure is Population III (Pop III) stars. These were the earliest stars in the universe, formed completely from pristine hydrogen and helium, with no "metals" (i.e., elements heavier than those two) polluting their processes.
Packaging already tells us where food comes from, when it was made, what's in it and how many calories it contains. But researchers see a future where packaging can "see," in real time, what's happening inside and translate that into information that producers and consumers can act on.
Metallic nanostructures are exceptionally effective at concentrating light into tiny volumes, while dielectric nanostructures excel at storing light with minimal energy loss. Combining these complementary properties has traditionally required complicated hybrid structures in which the two optical modes become mixed, making them difficult to control independently.
An international team of scientists, including Donald Danforth Plant Science Center member emerita Elizabeth "Toby" Kellogg, Ph.D., has produced a chromosome-level genome assembly that offers a new view of the earliest evolution of grasses, the plant family that includes many of the world's most important food crops.
New research shows how artificial intelligence, combined with advanced experimental science, can help find "hidden" and unexplored proteins in the human body and reveal what they actually do, according to a new study published in Nature.
Researchers from the Institute of Microbiology of the Chinese Academy of Sciences (IMCAS) have characterized the structural and functional properties of the emerging SARS-CoV-2 sublineage BA.3.2.2 by studying RE.2.2, the lineage designation for the BA.3.2.2 branch gaining prevalence after prolonged low detection in European surveillance datasets.
Researchers from Aarhus University and the Danish Technological Institute have taken a new approach in the search for enzymes capable of breaking down some of the most difficult types of plastic to recycle. They collected millions of bacteria from a landfill in Kenya, Randers Regnskov Tropical Zoo, the guts of larvae and a compost heap near Aarhus—and examined their enzymes. They found 12 that work.
Loose fibers from functional clothing, discarded PET bottles or abandoned packaging: When such plastic materials enter the environment, they often persist there for a long time. UV radiation, precipitation and ozone cause them to become brittle—and over time, mechanical forces break them down into increasingly smaller particles. Swirled up by the wind, they are carried farther through the atmosphere. Until now, it was unclear how much microplastic ends up back in Swiss soil and water bodies through this process.
Research teams from INRAE, the University of Clermont Auvergne and the CNRS have reconstructed 10 ancient genomes (paleogenomes) that are the common ancestors of 84 botanical species of agronomic interest. Their work makes it possible to identify particular genes, shared across different species of plants and retained throughout their evolutionary history, that might play a key role in adapting to environmental constraints such as drought.
Does the academic discipline of a scientist's doctorate accurately capture their disciplinary affiliation decades later? Consider a scientist who earned a doctorate in physics 25 years ago who now studies climate change, publishes primarily in interdisciplinary journals and considers herself a climate scientist. Does "physics" still accurately describe where she fits in science?
When will the glacier in your valley disappear? Will the glacier you visited as a child still exist in 2050? And how much difference would limiting global warming make?
Life is not always easy for a bee: Not all plants place their pollen outside. Some flowers have to be set to vibrating before the pollen can get out of their tube-like stamens. Certain bee species have developed a special technique for this: They bite on the flower and use their flight muscles to generate rapid vibrations. The stamen is shaken and the pollen is released. This phenomenon is known as "buzz pollination."
While chemical bonds usually determine the structure and properties of a material, bonds between neighboring metal atoms can also change as temperature or other conditions change. These changes can lead to unusual electronic and magnetic behaviors.
Scientists have identified the mechanisms that allow plants to change their root anatomy to maximize survival when nutrients are scarce. The findings could pave the way for developing new ways to improve beneficial plant-microbe interactions in agriculture.
OpenAI is at the center of another controversy over machines tackling big math problems. This one’s about the twin prime conjecture.
Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they do the next best thing: recreate those extreme conditions in the lab.
A study by Politecnico di Milano and the University of Insubria (Varese and Como) has been published in PLOS Digital Health. The study involved more than 700 children from primary and lower secondary school. The participants used the THInkPen (Tele-Health Ink Pen) while completing two BVSCO-3 tasks from the Battery for the Clinical Assessment of Writing and Orthographic Skills. This is the most widely used test in Italy for assessing writing difficulties, dysgraphia and dysorthography.
