Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected.
Large-scale oyster reef restoration in the Chesapeake Bay is successfully creating three-dimensional habitats that support larger, more diverse fish communities, according to new research from scientists at the University of Maryland, Baltimore County (UMBC), the Smithsonian Environmental Research Center and the National Oceanic and Atmospheric Administration (NOAA). The study, published in Ecosphere, provides compelling evidence that restoration efforts are shifting underwater ecosystems from communities dominated by small, transient schooling fish to those supporting larger, resident species.
When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, known as phonons. They may also collide with one another. Frustratingly, a conventional temperature test warms the electrons and the lattice together, so the effects arrive tangled in the same resistance measurement.
Forty-four years ago, Nadrian Seeman published his groundbreaking ideas on using DNA as a structural material, expanding DNA's significance far beyond its role as a carrier of genetic information. Since then, the steadily growing field of DNA nanotechnology has seen numerous innovations. One was the DNA origami technique, which enables researchers to fold a single long strand of DNA into a desired 2D or 3D shape.
A square peg doesn't fit a round hole. But what if the peg could change the shape of the hole? A newly developed drug molecule can do something surprisingly similar when binding to its target protein, according to a University at Buffalo-led study published Tuesday (Sept. 15) in Angewandte Chemie International Edition.
Sir John Gage, a key figure in Henry VIII's dissolution of the monasteries, saved a dangerous Catholic book from likely destruction, a new study suggests. The identification of six lost pages of a medieval bestseller—illicitly prized by Catholics in the Reformation—as belonging to Gage, exposes the split loyalties of one of Tudor England's great survivors.
Archaeologists have analyzed insect remains preserved in the 7th to 9th centuries AD funerary cave of Cruz de la Esquina, Gran Canaria, and found that it was used by the island's Indigenous people for food storage before being adapted into a burial site. The findings have been published in the journal Antiquity.
The ocean's aphotic zone—the dark, high-pressure region below the surface, where sunlight cannot reach—is home to a vast wealth of microbial life. Yet scientists know relatively little about the genetic makeup, growth and function of many of these enigmatic organisms.
Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small plant takes an unexpected route. In a new study published in Nature, an international team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne has shown that the Brazilian beak-sedge Rhynchospora tenuis reproduces sexually—producing pollen, fertilizing its egg cells and setting seeds—but has completely lost the reshuffling of DNA between chromosomes from each parent. The offspring retained the same genetic makeup as their mothers, effectively mimicking clonal reproduction.
In March 2026, scientists succeeded in transporting antiprotons by road for the first time in a purpose-built trap loaded on a truck. The BASE collaboration, which realized this experiment at the European Organization for Nuclear Research (CERN) in Geneva under the lead of Professor Dr Stefan Ulmer and Dr Christian Smorra from Heinrich Heine University Düsseldorf (HHU), now presents its findings and experiences from this pioneering experiment in the journal Nature. Among other things, they report that it was possible to store antiprotons in a mobile transport vessel for more than a month for the first time ever.
Eastern oyster larvae are only 100–300 micrometers long, but their dense calcium carbonate shells make them substantially heavier than the surrounding seawater. A new study led by the Woods Hole Oceanographic Institution (WHOI) shows that this excess weight allows gravity to drive the feeding currents the larvae use to bring food to their mouths, a finding that reveals a critical role for gravity in how these tiny animals feed and survive.
New research led by the ARC Center of Excellence for Transformative Meta-Optical Systems (TMOS) at the University of Melbourne demonstrates a new way to make invisible infrared light visible without relying on the expensive detector technology used in today's infrared cameras.
The Black Death is often remembered as a single catastrophic event that swept across Europe between 1347 and 1353, killing millions. Yet the disease did not disappear after that first devastating outbreak. For more than four centuries, plague continued to return in recurring waves, reshaping communities, economies and societies across Europe and beyond. A new study led by researchers at the University of Tartu sheds fresh light on this long and complex history by analyzing the DNA of the plague bacterium preserved in archaeological human remains. The study is published in the journal Proceedings of the National Academy of Sciences.
Oxford University researchers have captured the step-by-step assembly of individual virus-like particles, revealing how simple molecular interactions can reliably build these complex biological structures. The results were published today (September 16) in Nature.
In recent years, numerous attempts have been made to use artificial intelligence to decipher the communication of bats, whales, birds and other animals. However, a new study led by a team of researchers from Tel Aviv University points to a fundamental problem with this approach: AI models focus on the physical properties of a sound, but this does not mean they understand the meaning attributed to it by the animal receiving it.
Much of organic chemistry, including the type used to create and alter medicinal drugs, relies on modifying carbon bonds. Rice University's Julian West has been developing a less expensive, faster and more environmentally friendly way to catalyze these reactions, with a breakthrough published in the journal Nature Catalysis.
Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State's College of Agricultural Sciences. The research—published in Journal of Microbiological Methods—details a new method for detecting Pseudomonas syringae, a common bacterium that infects a wide variety of crops, vegetables and woody ornamentals.
Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: nanoscale infrared (IR) spectroscopy (s-SNOM) with ultrathin silicon-based membranes.
When it rains, traveling waves appear on steep asphalt pavement, slowly making their way down the slope. Because these so-called "roll waves" propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineering. Understanding unsteady flows like roll waves is crucial for the design, management and safety of hydraulic structures such as dam spillway chutes.
Researchers at Queen Mary University of London are closer to understanding tendinopathy, a common condition that can cause persistent pain and impaired movement in people and many animals.
