Jupiter hosts more than 100 moons, with most attention focused on the four Galilean moons: Io, Europa, Ganymede and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast subsurface liquid-water ocean beneath its icy crust. However, Jupiter
Metal-insulator transitions (MITs), in which a material changes from a metallic state with low resistivity to an insulating state because of a change in an external parameter, such as temperature, pressure or an electric field, are a central topic in fundamental physics research.
Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195
Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did not match well-established patterns seen in other similar explosions. Now, in a new study published in the Astrophysical Journal on Aug. 3, astronomers have revealed why.
History educators around the world have expressed concerns about declining history enrollments in schools and universities over the past few decades.
Humans have been observing the sky for thousands of years. Our ancestors were undoubtedly fascinated by it, but observing the heavens also had practical uses: It helped people measure time, both over the course of the day and through the changing seasons, and became especially important with the spread of agriculture. What is now seen as scientific frontiers, such as cosmology and astrophysics, are in fact only the latest chapter in an evolving history of observing and interpreting the sky.
When high or low tide occurs, the water does not necessarily rise and fall uniformly along the entire coastline. In fact, the height of the tide in a bay can vary by up to one meter (3 feet) from one location to another just a few kilometers away.

The intestines rely on different strategies to rebuild themselves in response to diet changes versus infections, according to a new Cornell study
Researchers from Tokyo Metropolitan University have created a new system to test magnetohydrodynamic aerobraking for spacecraft reentering the atmosphere. Their platform generates intense magnetic fields with a powerful electromagnet as a miniature vessel is hit with a shock wave traveling at over seven kilometers per second (4.3 miles per second). The magnets reached far higher fields than previous work with permanent magnets and are a crucial stepping stone toward tests with real vessels in th
On the surface, posting online reviews looks like a win-win activity. It helps both businesses we like and people who might frequent them. But although posting reviews can benefit others, it can also put us all at risk, according to new research from the McCombs School of Business at The University of Texas at Austin. It can inadvertently expose our personal connections and make us and our online friends more vulnerable to cyberattacks.
Lucerne seed wasp (LSW) is a serious pest in alfalfa crops, causing damage that is difficult to see in the field. Its larvae feed inside developing seeds, meaning losses may not become apparent until harvest, cleaning or seed delivery, when it is too late to intervene. Each wasp represents a lost seed, with infested seeds removed by seed-cleaning facilities along with other impurities.
Slithering across the ceiling of an Australian rock shelter is a giant snake with a crocodile-like head, razor-sharp teeth and a long tongue. It

Whether employees are worried about losing their jobs to AI depends largely on their knowledge of artificial intelligence
Researchers from North Carolina State University have created teardrop-shaped soft robots that leap upward or forward when exposed to infrared light
A research team has uncovered fundamental molecular mechanisms governing the formation of tendons and ligaments, which are essential for musculoskeletal integration. Understanding these mechanisms could pave the way for the regeneration of tendons, ligaments and their attachment sites, known as entheses, which have limited capacity for functional repair after injury because of their poor vascularization.
In a landmark development, Meta reached a proposed settlement Wednesday with U.S. states over claims that it designed Facebook and Instagram to hook children.
Spreading finely crushed basalt across farmland has been promoted as a relatively simple way to remove large quantities of carbon dioxide from the atmosphere. But a new study led by Cornell researchers suggests the real-world potential of this method, known as enhanced weathering, may be far smaller than widely cited estimates.
Model checking helps automatically verify whether hardware and software systems satisfy specified requirements. It has become an important formal verification technique, but two major challenges remain: state-space explosion, which limits the size of systems that can be checked, and long verification times.
Before you prompt AI to answer another question or perform another task, a Wake Forest computer scientist wants you to know it could expose your sensitive data.
Meta agreed to pay a coalition of U.S. states as much as $16.7 billion and to impose sweeping new limits on how teenagers use Facebook and Instagram, according to a court filing Wednesday that ends a landmark trial in California.
A research team has developed a flexible near-infrared (NIR) photodetector that delivers photoresponsivity more than five times higher while maintaining its performance under repeated bending. The technology is expected to serve as a core platform for next-generation flexible optoelectronic devices, including wearable health care devices, medical diagnostic sensors and optical communication receivers.
Fuel cells, devices that generate electricity by converting the chemical energy of hydrogen or other fuels via electrochemical reactions, are promising solutions for powering large electric vehicles, industrial sites and remote facilities. To drive the necessary reactions, solid oxide fuel cells rely on ceramic, heat-resistant electrolytes, solid materials that transport ions between two electrodes.
The next time you need to freshen up the paint on your house or apply a bit of cosmetic glitter before heading out for the night, you might want to give a quick nod to the butterflies fluttering in a nearby garden. Taking inspiration from structures on those wings that create their vibrant colors, researchers are now devising more durable and adjustable colors that are also safer for human health and the environment.
Many Native American communities in rural areas rely on well water, but the quality and safety of that water can vary significantly. Researchers led by Jani C. Ingram measured levels of heavy metals in well water on tribal lands through a community partnership with the Navajo Nation. After compiling their water-quality data, the researchers and tribal leaders developed best practices for distributing educational resources about safe drinking water to residents of Navajo reservations.
A new study that combines paleoclimate data and climate models suggests that large volcanic eruptions can disrupt the relationship between atmospheric circulation patterns over the tropical Indian and Pacific oceans. In addition, human-caused greenhouse gas emissions are now driving an unprecedented breakdown in interbasin coupling, according to researchers at the Woods Hole Oceanographic Institution (WHOI).
A large-scale study of nearly 700 species reveals the evolutionary relationships and history of Neogastropoda, a diverse group of marine snails. The findings provide new evidence for their single origin, identify four new families and reveal a previously undetected burst of diversification in the early Cenozoic.
Consumer detectors sold to help people find hidden surveillance devices are often too difficult for typical users to interpret, potentially giving a false sense of security to those most at risk such as domestic abuse survivors, finds a new study led by UCL researchers.
Semiconductor devices such as LEDs and transistors generally consist of two halves: an n-type, which carries negative charge via electrons, and a p-type, which moves positive charge carriers called holes that are essentially electron voids. Both halves rely on contacts that allow electric current to flow in and out with minimal energy loss. These connections, known as ohmic contacts, have been an efficiency bottleneck in thin p-type GaN semiconductors for decades because of their high resistance
Experts have shown that the most powerful security defenses in Windows 11 can be dismantled by an attacker who never touches the target computer.
For people who are blind or have low vision, moving around independently is a daily challenge. Harvard researchers have developed a new tool that could help people navigate more quickly and safely with nothing more than a device they likely already have
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct chromosomes to recognize one another.
Researchers from Tokyo Metropolitan University have used a theoretical framework to derive design rules for creating new thermoelectric materials. The efficiency of converting thermal energy to electricity is often determined by parameters that strongly depend on each other, making it difficult to identify ideal recipes.
New research from Cardiff University and the University of Melbourne has investigated whether GenAI could mimic human marking when evaluating written student work. The results have been published in the journal Assessment
A 12-year study of rescued chimpanzees at the Ngamba Island Chimpanzee Sanctuary (NICS) in Uganda has revealed persistent intestinal schistosomiasis infections, highlighting the need for long-term disease surveillance to protect endangered wildlife.
Researchers at UC San Diego and UC Berkeley have found that certain landscapes surrounding California communities are associated with differing rates of Valley fever, a fungal respiratory infection caused by inhaling spores carried in windblown dust.
Immigration can produce a small economic gain for the native-born population overall while causing larger shifts in wages between different groups of workers, according to new research co-authored by King
Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While each pair eclipses its own two stars, as usual, only one pair eclipses the other. A paper outlining the properties of this unique system was submitted to the arXiv preprint server on Aug. 13. It has been accepted for publication in the journal Astronomy
For more than two decades, silicon carbide (SiC) has been promoted as the key to developing extreme-environment electronics. Yet despite its promise, the field has remained stuck at the stage of basic research, failing to result in the development of practical devices. Now, a team of researchers at Kyoto University has set out to change that.
