An earthquake typically sets off ruptures that ripple out from its underground origins. But on rare occasions, seismologists have observed quakes that reverse course, further shaking up areas that they passed through only seconds before. These "boomerang" earthquakes often occur in regions with complex fault systems. But a new study by MIT researchers predicts that such ricochet ruptures can occur even along simple faults. [...]
A research team led by Professor Tae-Woo Lee has developed a technology to mass produce ultra-high color purity perovskite nanocrystals (PeNCs), the core material for next-generation displays, without the need for high temperature, vacuum, or specialized gas facilities. This study, which proves that 100% photoluminescence quantum yield (PLQY) can be maintained from lab to industrial scale, was published in the journal, Nature, on February 18, 2026. [...]
Due to climate change, extreme weather events such as flooding are expected to increase in Germany in the future. This poses hidden risks to the health care system that have hardly been the focus of resilience planning to date: restrictions on access to hospitals and the supply of medical products due to flood-related traffic disruptions. [...]
Up to 30% of bird diversity hotspots, places where large numbers of different bird species occur, in the western United States face threats from high-severity wildfires in the future that could eliminate critical forest habitats, according to research published in the journal Nature Communications. [...]
Birds currently inhabiting many territories across Africa, Latin America and Asia are, on average, considerably smaller than those that predominated in 1940. This is the conclusion of an international study led by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), which documents—drawing on the collective ecological memory of 10 Indigenous Peoples and local communities—a reduction of up to 72% in the mean body mass of the bird species present in their territories between 1940 and 2020. [...]
In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the kitchen table, it will eventually melt and become room temperature. That concept rooted in energy transport is known as thermalization, and it is easy to comprehend because we see it happen every day. But this is not always how things behave at the smallest scales of the universe. [...]
Researchers at the University of Oklahoma have developed new hybrid materials that challenge conventional thinking about how light-emitting compounds work and could advance the field of fast radiation detection. The research, published in the Journal of the American Chemical Society, presents a novel approach to designing layered perovskite materials that combine the best of both organic and inorganic components. [...]
University of Missouri researchers have released the world's largest collection of protein models with quality assessment—a groundbreaking new resource that could accelerate drug development for diseases such as Alzheimer's and cancer. The database, called PSBench, includes 1.4 million annotated protein structure models, all verified by independent experts. It gives scientists the reliable information they need to build more accurate artificial intelligence (AI) systems for assessing the quality of protein structure models, which is critical for developing future medical treatments. [...]
Scientists have pinpointed crucial genetic resistance to a fungal disease that threatens the global banana supply in a wild subspecies of the fruit. In a valuable step forward for banana breeding programs, Dr. Andrew Chen and Professor Elizabeth Aitken from the University of Queensland have identified the genomic region that controls resistance to Fusarium wilt Subtropical Race 4 (STR4). The study is published in the journal Horticulture Research. [...]
A research team led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) has published a foundational inventory of emissions produced by structures destroyed by fires in the wildland-urban interface (WUI). Previously, researchers suspected that fires in WUI areas—spaces where human development and undeveloped wildland meet—produce emissions that are likely more harmful than those produced by forest or grass fires. However, the amount of emissions had not been quantified. [...]
An ecosystem is not a still life. Even where everything looks stable—a woodland, a lake, the soil—the internal "bookkeeping" keeps changing: how many individuals belong to which species, and for how long. Some populations expand, others crash. That dynamism is part of what we call biodiversity, but it also carries risk: when numbers are very low, chance events and short spells of unfavorable conditions can increase the likelihood that a species disappears locally. [...]
In a paper published in the journal Small, a team of physicists from IISER Pune have developed tiny electronic devices from a special semiconductor material called bismuth oxyselenide (Bi2O2Se). This development has potential applications in future flexible smartphones, wearable health monitors, smart fabrics, and bendable electronic gadgets. [...]
By applying new methods of machine learning to quantum chemistry research, Heidelberg University scientists have made significant strides in computational chemistry. They have achieved a major breakthrough toward solving a decades-old dilemma in quantum chemistry: the precise and stable calculation of molecular energies and electron densities with a so-called orbital-free approach, which uses considerably less computational power and therefore permits calculations for very large molecules. [...]
Despite rare earth elements' importance in manufacturing cell phones, magnets and a host of other consumer and commercial electronics, the lack of a sustainable, environmentally friendly approach to obtaining these metals has led to a global shortage, according to Amir Sheikhi, associate professor of chemical engineering at Pennsylvania State University. [...]
Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales. The narrowest regions of ion channels can be just a few angstroms wide, about the size of individual atoms, making reproducible and precise fabrication a major challenge in modern nanotechnology. [...]
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein synthesis machinery, and blurs the line between cellular life and viruses. [...]
For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its limits. In a perspective article published in the journal Genetics, an international group of leading geneticists and evolutionary biologists, including Detlef Weigel, Director of the Department of Molecular Biology at the Max Planck Institute for Biology Tübingen and Luisa Pallares, Max Planck Research Group Leader at the Friedrich Miescher Laboratory in Tübingen, calls for a fundamental shift in focus: away from searching for isolated, clearly defined gene effects and towards experimental approaches that treat genetic complexity not as noise, but as the starting point. [...]
Violence and harassment in Canadian schools have reached such crisis levels that these public institutions should be categorized as hazardous workplaces, says a national report conducted by researchers in the School of Psychology and the Department of Criminology at the University of Ottawa. [...]
Researchers at Case Western Reserve University have discovered a way to breach one of cancer's most stubborn defenses: the impenetrable fortress that solid tumors build around themselves. [...]
Corralling a wild rhinoceros into a small chute to give it eyedrops might seem like a crazy plan. But if it's crazy and it works, then it's not crazy. [...]
Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the number of possible interactions between quantum bits before a serious error occurs in the highly sensitive system. For this reason, it is important to keep computing operations as efficient and lean as possible. [...]
A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a significant step in the treatment of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. Dr. Travis Craddock, a professor of biology at the University of Waterloo and Canada Research Chair in Quantum Neurobiology, led the research team that is the first to use weak magnetic fields and isotopes to change the structure of cells. [...]
A Purdue University digital forestry team has created a computational tool to obtain and analyze urban tree inventories on public and private lands with record-breaking speed at an unprecedented scale. The team accomplished the feat by developing a novel AI-enhanced visual computing method that accurately determines the locations of trees in over 330 U.S. cities with a population of 100,000 or more. The method so far has individually identified 280 million urban trees. [...]
The performance of rechargeable batteries is governed by processes deep within their components. A fundamental understanding of electrochemistry, structure–property–performance relationships and the effects of processing and operating conditions is essential for accelerating the development of next-generation battery technologies capable of powering electric vehicles, portable electronic devices and grid-scale energy storage. [...]
In the vast tapestry of the universe, most galaxies shine brightly across cosmic time and space. Yet a rare class of galaxies remains nearly invisible—low-surface-brightness galaxies dominated by dark matter and containing only a sparse scattering of faint stars. [...]
A new study from the School of Neurobiology, Biochemistry, and Biophysics reveals a surprising insight into the operation of the ancestral brain: the visual cortex of turtles is capable of detecting unexpected visual stimuli in a way that is independent of their position on the retina, a property that, until now, was thought to exist only in the highly developed cortices of mammals, including humans. In light of these findings, the research team assesses that advanced brain mechanisms previously thought to be unique to mammals were already present hundreds of millions of years ago. [...]
Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on its own from countless interactions between molecules that are constantly moving and rearranging. One of the most striking examples of this emerging order is the left-right asymmetry. [...]
Proteins often function in pairs or groups, concealing their internal connection points and making it difficult for scientists to study their individual units without altering their natural structure. In a study published in the Journal of the American Chemical Society, researchers successfully isolated single units of the protein SOD1, which is linked to amyotrophic lateral sclerosis (ALS), by chemically tagging the protein and encapsulating it within tiny, self-assembled artificial cages. [...]
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, as they explain in a paper available on the arXiv preprint server. [...]
The Antarctic ice sheet does not behave as one single tipping element, but as a set of interacting basins with different critical thresholds. This is the finding of a new study by the Potsdam Institute for Climate Impact Research (PIK) and the Max Planck Institute of Geoanthropology (MPI-GEA). With today's warming, about 40% of the ice stored in West Antarctica may already be committed to long-term loss, while parts of East Antarctica could cross thresholds at moderate levels of warming between 2 to 3°C compared to pre-industrial levels, contributing significantly to global long-term sea-level rise.
