Alzheimer's disease is best known for its effects on memory and cognition, but the disease also involves changes in how brain cells produce and use energy. Mitochondria, the structures that supply much of a cell's energy, can become dysfunctional in Alzheimer's disease. At the
Naming a chicken and describing its favorite habits is enough to make preschoolers choose poultry less often. This effect translates into verbal declarations and actual meal choices, but food preferences still most often win over empathy, according to a new paper by researchers
What happens when political violence is presented as a justified response to threat or injustice coming from an out-group? A study by Ursula Daxecker, director at the Max Planck Institute for Politics and Social Science in Göttingen, and Neeraj Prasad of the University of
Scientists have discovered a gene that determines whether Japanese snails develop shells that are left- or right-coiling—with implications for understanding the underlying handedness of our own bodies. The researchers from the University of Nottingham and Tohoku University
The European rabbit is a common sight in the British countryside today. Yet it was not always so. They are not native to the British Isles and are one of the most devastating invasive species.

Plants begin responding to spaceflight almost immediately after leaving Earth, according to a new University of Florida study that captured the earliest stages of biological adaptation during a commercial suborbital mission. Published in the journal npj Microgravity, the study
How do young stars reshape the clouds from which they are born? A new high-resolution 3D model developed by an international team led by Dr Brandt Gaches from the University of Duisburg-Essen shows how the uneven structure of stellar nurseries creates shadows that alter their
Every time a tissue grows or renews itself, cells must divide inside an already crowded environment. That creates a fundamental problem that scientists have not fully understood: How does a tightly packed sheet of cells make room for two daughter cells when there was once only
Andrew Tate, a self-described misogynist and an online influencer with millions of followers, faces charges in several countries of allegedly causing physical harm, including rape and sex trafficking of women and girls.
Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, developing and fine-tuning quantum computers requires
Australian researchers and international collaborators have demonstrated a solar-driven approach to convert glycerol, a low-value byproduct of biodiesel production, into hydrogen and higher-value chemicals. Using advanced techniques at the Australian Synchrotron, they revealed
For the first time, scientists have achieved strong coupling between light and long-lived acoustic vibrations in an optical fiber. Optical fibers are used in both classical telecommunications and quantum communication and could serve not only as connections between computing
Researchers have developed and tested a new locking method for gravitational wave detectors that will advance the discovery of distant black holes and neutron stars colliding.
A Ph.D. student at the University of Sydney has produced the first comprehensive classification system and map of Martian soils, creating a new framework that could help scientists compare landscapes across the Red Planet and identify promising locations for future exploration,
Researchers already know that humans have a tendency to use egocentric anchoring—a cognitive bias in which people use their own preferences, beliefs and perspectives as a mental starting point (or anchor) to understand or predict what another person thinks, feels or prefers.

A German cockroach races across a kitchen floor. Someone grabs a bottle of essential oil spray, soaks the insect and watches it die. The product worked, but a new University of Kentucky study suggests the larger infestation probably did not notice.
A new University of Melbourne-led study has identified insights and evidence that could help mitigate the fast-rising climate impact of lithium-ion batteries (LIBs).
With the 2026 midterm elections around the corner, voters may be feeling everything from excitement to fear. But how might anger motivate political activism and, ultimately, influence who turns out to vote?
A Université de Montréal–led research team has analyzed the genetic origins of human remains found in Old Montreal—and uncovered unexpected results.
A viral documentary has everyone talking about Elizabeth Holmes’s fraudulent blood testing start-up again—but scientists never stopped
A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate affects them. New Dartmouth-led studies look at the
Most natural gas leakage in Indianapolis likely originates from homes and other buildings, not exterior pipelines and large-scale distribution infrastructure that deliver the fossil fuel, according to Penn State researchers who assessed nearly a decade of data.
Structural metals used in engineering projects are expected to have both high strength and high ductility: the ability to withstand heavy loads and deform before failure. Achieving both of these properties at the same time, however, is challenging.
Sustainable packaging is only the beginning. What a medicine is made from—and how its ingredients are produced—matters just as much. Yet the synthesis of compounds for pharmaceutical research can still depend on fossil feedstocks, high temperatures, strong oxidants and metals
Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair.
An artificial intelligence (AI) model can score English essays with improved accuracy across different writing topics, according to work published in the International Journal of Continuing Engineering Education and Life-Long Learning. The tool could help schools assess student
Cortisol is a hormone that helps humans and many other animals regulate their energy use and respond to changing conditions. For a long time, sharks and rays were believed to rely on a different steroid hormone for these functions, without producing cortisol themselves. Now, a
Since its introduction more than 150 years ago, the thought-provoking idea of Maxwell's demon has profoundly shaped our understanding of the relationship between information and energy. Maxwell's demon is an imagined microscopic gatekeeper that exploits information at the
With up to 75% of the world's soils degraded, restoration projects try to reestablish functional and biodiverse environments to secure adequate food production, biodiversity, climate regulation and human well-being.
From the hairs on our arms to the microscopic sensory structures of the inner ear, many tissues in the body are built with a clear sense of direction. To build these structures throughout development, individual cells must establish which way they are facing—and coordinate that
A new study has found that adaptive molecular convergence—the process by which distantly related or unrelated species evolve the same genomic changes—is not as rare as previously thought.
