While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ultrasound to reveal capillaries and cells across living organs -- something that wasn't possible before.

A switch of just two weeks from a traditional African diet to a Western diet causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Conversely, an African diet rich in vegetables, fiber, and fermented foods has positive effects. This study highlights the significant impact of diet on the immune system and metabolism.

A solar wind event from 2017 that hit Jupiter and compressed its magnetosphere created a hot region spanning half Jupiter's circumference.

The same dirt that clings to astronauts' boots may one day keep their lights on. Researchers created solar cells made out of simulated Moon dust. The cells convert sunlight into energy efficiently, withstand radiation damage, and mitigate the need for transporting heavy materials into space, offering a potential solution to one of space exploration's biggest challenges: reliable energy sources.

A new study has found that the world's finest yodellers aren't from Austria or Switzerland, but the rainforests of Latin America. The research provides significant new insights into the diverse vocal sounds of non-human primates, and reveals for the first time how certain calls are produced. The researchers have discovered that special anatomical structures called vocal membranes allow monkeys to introduce 'voice breaks' to their calls. These have the same rapid transitions in frequency heard in Alpine yodelling, or in Tarzan's famous yell, but cover a much wider frequency range.

An international team has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing.

For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe. The James Webb space telescope now reveals that galaxies stopped forming stars earlier than expected. A recent discovery deepens the tension between theoretical models of cosmic evolution and actual observations. Among hundreds of spectra obtained with the Webb program RUBIES, the team has found a record-breaking galaxy that had already stopped forming stars during an epoch where galaxies are normally growing very rapidly.

An international team is currently closely tracking the near-Earth asteroid 2024 YR4. The impact probability estimates for the year 2032 has been reduced from a peak of 3 percent to below 0.001 percent.

A new kind of press-on nails come in all shapes and colors -- and when you're done with them, you can melt them down and reuse the materials to make your next look.

In new images, scientists have gotten the closest look yet at Sagittarius C -- a 'stellar nursery' where clouds of gas and dust have collapsed to form thousands of new stars.

Miso is a traditional Japanese condiment made by fermenting cooked soybeans and salt. Researchers successfully made miso on the International Space Station (ISS). They found that the miso smelled and tasted similar to miso fermented on Earth -- just with a slightly nuttier, more roasted flavor. The team hopes this research will help broaden the culinary options available to astronauts, improving the quality of life for long-term space travelers.

Researchers interrogated the 'sounds' of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution.

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light.

Medical imaging experts are adept at solving common optical illusions, according to new research. The research is the first to show that people can be trained to do better at solving visual illusions, which was previously thought to be near-impossible. The study shows that medical imaging experts are particularly accurate at judging the size of objects in common optical illusions. In other words, they also literally see better in everyday life!

Every night, bats emerge out of roosts in massive numbers, creating what scientists have called a 'cocktail party nightmare' of clashing echolocations. Nobody knew how bats managed this severe sensorial challenge. Now, scientists have tracked bats within a group of thousands to find out: when bats first emerge from the roost, they increase their distance from the center of the group and adjust their echolocation to maneuver safely in the areas of highest bat density.

Cold water immersion for seven days significantly improves cellular resilience and autophagic function, helping cells manage stress better. This adaptation could enhance health and longevity, potentially preventing diseases and slowing aging at a cellular level.

Novel artificial neurons learn independently and are more strongly modeled on their biological counterparts. A team of researchers has programmed these infomorphic neurons and constructed artificial neural networks from them. The special feature is that the individual artificial neurons learn in a self-organized way and draw the necessary information from their immediate environment in the network.

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to quantitatively describe the much more complex rolling physics of real-world objects. They have now combined theory, simulations, and experiments to understand what happens when an imperfect, spherical object is placed on an inclined plane.

Researchers have discovered brand new interference patterns in twisted two-dimensional tungsten ditelluride lattices. These so-called moir patterns can be tuned to look like periodic spots or even one-dimensional bands by adjusting the twist angle between layers, and they can drastically alter the physical properties of the material.

The reuse of human urine would allow for the production of sustainable fertilizers for urban agriculture, with significant environmental benefits, a new study concludes. The research evaluates the environmental impact of nitrogen recovery from the yellow waters of buildings. In addition to promoting sustainable agriculture, it would reduce carbon dioxide emissions and water consumption.

Imagine navigating a virtual reality with contact lenses or operating your smartphone under water: This and more could soon be a reality thanks to innovative e-skins. A research team has developed an electronic skin that detects and precisely tracks magnetic fields with a single global sensor. This artificial skin is not only light, transparent and permeable, but also mimics the interactions of real skin and the brain.

Researchers asked generative AI to write a research paper. While adept at some steps, it wholly failed at others.

Researchers conducted the first clinical trial of an AI-powered therapy chatbot and found that, on average, people with diagnosed mental disorders experienced clinically significant improvements in their symptoms over eight weeks, according to new results. Users engaged with the software, known as Therabot, through a smartphone app and reported that interactions were comparable to working with a mental-health professional. The researchers conclude that while AI-powered therapy is in critical need of clinician oversight, it has the potential to provide real-time support for the many people who lack regular or immediate access to a professional.

Most haptic devices only deliver feedback as simple vibrations. New device applies dynamic forces in any direction to simulate a more realistic sense of touch. Small, lightweight device can enhance virtual reality, help individuals with visual impairments, provide tactile feedback for remote health visits and more.

A new species of fossil is 444 million years-old with soft insides perfectly preserved. Research 'ultramarathon' saw palaeontologist puzzled by bizarre fossil for 25 years.
