As global audiences follow ongoing conflicts, stories of personal sacrifice often stand out. New research from the Kelley School of Business shows that people across the United States consistently view self-sacrificial actions as more heroic and inspiring—even when they lead to
The ability to control the movement of negatively charged particles (i.e., electrons) is central to the functioning of all modern electronic devices. This control is typically attained using a gate, an electrode via which an applied electric field alters a material's electrical
If the supernova remnant is confirmed, it would be one of the closest to the supermassive black hole that lies in the center of the Milky Way
This young researcher’s unlikely journey into academia will change the way you think about science, failure and belonging
Climate change is altering where and when rocks are most likely to fracture across Spain, according to new research that suggests warming temperatures are redistributing a key process responsible for breaking down mountain landscapes.
Bee species that nest in plant stems appear to be at the greatest short-term risk from increasing temperatures due to climate change, while those that nest in the ground are better able to evade extreme heat, according to new research from Australian evolutionary ecologists.
On his fishing boat moored in the Greek port of Ierapetra in southwestern Crete, Alexis Charlambakis pries open the mouth of a freshly caught pufferfish to reveal two massive teeth on each jaw.
Oxford physicists have created an entirely new type of Schrödinger’s cat-like quantum state using components that are themselves highly quantum in nature. The advance could open new possibilities for more resilient quantum computers and deeper insights into the strange rules
Beneath our feet lies a vast hidden fungal superhighway that helps sustain much of life on Earth—and scientists have now mapped it for the first time. Researchers estimate that these underground networks stretch an astonishing 110 quadrillion kilometers, move about 4 billion
A new whey protein manufacturing technique could make protein shakes taste better and feel smoother in the mouth. Researchers traced unwanted bitterness to concentrated minerals and found a way to remove them without sacrificing the improved texture.
Citizen science data from the popular platform iNaturalist has helped uncover the evolution of parental guarding behavior in harvestmen spiders, as shown in research published in the Zoological Journal of the Linnean Society.
A method to interpret artificial intelligence (AI) models used in materials discovery by analyzing their learned features has been developed by researchers from Japan. The method extracts key features from an AI model trained on atomic structural data and optical absorption
The UK Space Agency has announced an agreement with Vast—a US commercial space company—that could send British astronaut John McFall into orbit as early as 2027. If the mission goes ahead, he would become the first person with a physical disability to live and work in space.
Sulfur is one of the most abundant elements in the universe. If you peer into a diffuse interstellar cloud, you find loads of it—about the amount expected based on fusion patterns in the stars it was born in. However, if you look at a dense, cold molecular cloud—the kind where
We see glass objects every day and often don't think much about them. Mass-produced glass has become so cheap we barely think about the things it allows us to do.
One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner and thinner, most people would expect it to become
Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path. Some repeated their routes so precisely that they flew only centimeters from where they had flown before. Landmarks like trees helped
Scaffolded DNA and RNA origami is a technique that allows scientists to build tiny, highly precise two- and three-dimensional objects. Because these nanostructures can interact naturally with biological systems, they could have important future uses in health care and agritech.
The increased public attention on racial injustice after the murder of George Floyd influenced how Black and white employees interacted at work, new University of Washington research suggests. The study, recently published in the Academy of Management Journal, examines how
Steel and metal production are among the largest contributors to global greenhouse gas emissions, accounting for approximately 10% of global CO2 emissions. At the same time, modern technology relies on tailored steels and metals for applications in fields such as mobility,
A debate has been raging among planetary scientists for more than a decade—why are there so few exoplanets with a radius of about 1.8 times that of Earth? Exoplanets are currently largely grouped into two distinct categories—"super-Earths" are below that size and have rocky
Few animals put on a show quite like manakins. In the rainforests of Central and South America, males of these small tropical birds, with strikingly bright plumage, often gather at communal display sites (leks), where they clear their own dance courts and spend much of their
Many insects will eat almost anything in their sight, such as certain beetles, grasshoppers and locusts, while others are remarkably picky eaters. For example, numerous insect herbivores will feed only on a single plant family or a specific type of tree. But why is this so?
Archaeological evidence from the Canary Islands suggests that by the 11th century, people there were harvesting and processing a variety of fish and other marine organisms—indicating that coastal resources may have played a vital role in the economic system, according to a
If we're to reach another star, chemical propulsion will not get us there in any reasonable time frame. We're going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These giant reflective surfaces form the basis of many
When a whale dies, a very special natural phenomenon can come alive. The carcass might float at the surface for some time, attracting sharks and other predators. As it becomes weathered, it may start to sink, falling through the water until it eventually settles on the
Most people have seen nylon listed as a material on their clothing tags, but nylon is used in an array of other products, too, including automotive parts, wire insulation and medical supplies. Unfortunately, one of the building blocks of nylon, adipic acid, is produced from
In a first, a large, international team led by multiple labs at Harvard Medical School and Princeton University has published a complete wiring diagram of all the connections between neurons in the central nervous system of an adult fruit fly.
Parents who come down hard on their children for telling lies or misbehaving may believe they are teaching the child right from wrong. But new research by NUS suggests that overly strict or punitive parenting could be part of what drives the behavior in the first place.
Archaeologists digging at an Inca site on the arid coast of southern Peru have unearthed two rare, roughly 500-year-old freeze-dried potatoes. The potatoes are among the only ones found in more than a century and would have been transported across the empire from the freezing
Some barley beers labeled "gluten-free" contain small amounts of gluten residues that may trigger celiac disease but are not detected by the standard antibody-based tests currently in use, according to a study by the Leibniz Institute for Food Systems Biology at the Technical
A new study reveals that, for the first time, areas of Canada's boreal peatlands damaged by oil and gas exploration have failed to recover as scientists and companies predicted and instead have led to a tripling of methane emissions, with global implications. The study,
Engineers often treat impurities as a problem to eliminate to improve material performance. But new research from Osaka Metropolitan University and Fraunhofer Institute for Mechanics of Materials IWM suggests that in some cases, a little chemical messiness is exactly what helps
Early biological systems likely relied on RNA molecules to copy themselves and drive simple chemical reactions. Any system that could generate guanosine-triphosphate (GTP)—which is necessary for RNA synthesis—from prebiotic chemicals would gain a crucial advantage toward
Bringing blood sugar levels back to normal may dramatically reduce the danger posed by prediabetes. Researchers found that people who reversed prediabetes cut their risk of cardiovascular death or hospitalization for heart failure by 58% and lowered their chances of major heart
A new catalyst design could significantly improve the conversion of CO2 into methanol, an important fuel and chemical feedstock. Researchers separated key reaction steps across different catalyst sites, avoiding a long-standing trade-off between speed and efficiency. The result
Researchers at the UCLA Samueli School of Engineering and CNSI (California NanoSystems Institute), led by Professor Aydogan Ozcan, introduced a snapshot 3D image projection system that integrates a digital encoder with a passive diffractive optical decoder, jointly optimized
Using data from NASA's Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings was published in The Astrophysical Journal.
Fossilized poo harbors remains from mammoths, bison and big cats, including some of the oldest DNA ever reconstructed
Digital matching platforms—from professional networking to ride-sharing and accommodation services—add value by bringing supply and demand into balance. But deep-seated asymmetries can prove difficult to expunge, causing platforms' functionality and productivity to suffer. This
