A study now published in Nature Communications brings remarkable insights into the enigmatic behavior of supercritical fluids, a hybrid state of matter occupying a unique space between liquids and gases, and arising in domains that go from the pharmaceutical industry to planetary science. The obtained results are at the limit of current experimental possibilities and could only be obtained in a high flux neutron source such as the Institut Laue-Langevin (ILL). [...]

According to a study published in Current Biology on May 22, the genetic components of the ancient populations in the western Tibetan Plateau are closest to ancient populations in the southern Tibetan Plateau, and their major genetic components have been maintained over the past 3,500 years. In addition, these ancient populations in the western Tibetan Plateau had complex and frequent interactions with ancient populations inside and outside the plateau. [...]

New research by EMBL scientists shows how different modes of cell division used by animals and fungi might have evolved to support diverse life cycles. [...]

Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable. The chemical method identified to tackle hard-to-recycle packaging material, cutting landfill waste [...]

Scientists at Bath, have introduced a breakthrough carbon-based sensor for detecting lactic acid levels in saliva—avoiding the need for an electrical power source. [...]

Researchers from TU Delft and Brown University have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object—approaching what is currently only achievable near absolute zero temperatures. Their study, published in Nature Communications, pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors. [...]

In the rapidly evolving field of photonics, an advancement has emerged from Korea, redefining the possibilities of structural color manipulation. Scientists have developed a pioneering technology capable of omnidirectional wavelength tuning, which promises to revolutionize a myriad of tunable photonic applications. [...]

Discoveries and progress in materials science often lay the foundation for technological breakthroughs that reshape many industrial and commercial fields, including medicine, consumer electronics, and energy generation, to name a few. [...]

Rising sea levels and urban development are accelerating coastal erosion at an alarming rate in Southern California with significant ripple effects on the region's economy, a USC study reveals. [...]

Nature lovers will know the scene well. A flurry of birdsong, a shake of a tree and out pops a flock of birds flying away in unison together. [...]

The National Institute for Materials Science (NIMS) has established a technique for cultivating human mesenchymal stem cells, widely used in regenerative medicine, on the surface of an ionic liquid. [...]

Genetic predispositions guide population-specific song learning in wild birds, shows new research from Stockholm University. By studying adult pied flycatchers that had been translocated as eggs from the Netherlands to Sweden, the researchers found that the songs of translocated birds resembled both their social environment in Sweden as well as their ancestral Dutch population. [...]

Australia lacks fearsome large carnivores like lions and wolves, and the relative lack of fear that marsupials like kangaroos and wallabies show to dogs (and other introduced carnivores) has been attributed to a lack of evolutionary experience with large mammalian predators. This, however, overlooks the 50,000-year-long presence in Australia of the world's most fearsome predator—the human "super predator." [...]

The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is generated deep within the star. But an MIT study finds that the sun's activity may be shaped by a much shallower process. [...]

Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. [...]

We've been told, "The eyes are the window to the soul." Well, windows work two ways. Our eyes are also our windows to the world. What we see and how we see it help determine how we move through the world. In other words, our vision helps guide our actions, including social behaviors. [...]

Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel. [...]

Researchers in Carnegie Mellon University's Department of Chemistry have developed a nucleic-acid-based photocatalyst that can precisely control atom transfer radical polymerization (ATRP), a popular method used to generate a wide range of materials with highly specific, tailored functionalities. [...]

An international study headed by the University of Bonn has now demonstrated the important role of the plant root system in maize, a crop that can grow successfully in very different local conditions. [...]

Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. [...]

For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a telescope or microscope. [...]

A solitary, wandering weasel species capable of traversing mountain passes and covering up to 15 miles a day will return to Colorado after a century-long absence. [...]

A research team, jointly led by Professors Jiyun Kim, Chaenyung Cha, and Myoung Hoon Song from the Department of Materials Science and Engineering at UNIST, has unveiled the world's first flexible, biodegradable bioelectronic paper with homogeneously distributed wireless stimulation functionality for simple personalization of bioelectronic implants. [...]

The first crewed launch of Boeing's Starliner spacecraft to the International Space Station has again been delayed, according to NASA, with no new date immediately set. [...]

Researchers have shown how different swimming formations may save fish energy and suggest that they only switch positions to save energy for the group when under pressure. [...]

In a study published in Science Advances, Prof. Wang Can from the Institute of Physics of the Chinese Academy of Sciences and Prof. Xu Xiulai of Peking University have demonstrated for the first time the dependence of valley polarization switching and polarization degree on the moiré period by twist engineering in electrically controlled transition metal dichalcogenide heterobilayers (hBLs).

Quantum computers, computing devices that leverage the principles of quantum mechanics, could outperform classical computing on some complex optimization and processing tasks. In quantum computers, classical units of information (bits), which can either have a value of 1 or 0, are substituted by quantum bits or qubits, which can be in a mixture of both 0 and 1 simultaneously.
