Scientists have forced a solid magnetic metal into a spin liquid state, which may lead to insights into superconductivity and quantum computing.

A researcher has used new detection methods to identify 85 previously unknown submarine landslides that occurred in the Gulf of Mexico between 2008 and 2015, leading to questions about the stability of oil rigs and other structures, such as pipelines built in the region.
Physicists have found surprising evidence of a link between the 2D quantum Hall effect and 3D topological materials that could be used in quantum computing.
Humans have been wondering whether we alone in the universe since antiquity. We know from the geological record that life started relatively quickly, as soon our planet's environment was stable enough to support it. We also know that the first multicellular organism, which eventually produced today's technological civilization, took far longer to evolve, approximately 4 billion years.
Until recently, researchers have not inspected the interplay between three common chemicals found in drinking water. Research has now found they all affect each other and a closer look is needed.
In almost every region of the world where hurricanes form, their maximum sustained winds are getting stronger. That is according to a new study involving an analysis of nearly 40 years of hurricane satellite imagery.
A new study has shown for the first time the full extent of the areas burned by Victorian bushfires over the past two decades.
Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct 'fight or flight' and 'rest and digest' circuits. These results explain how mental states can affect the gut, and present new ways to treat gastrointestinal problems.
It's not just the presence of bacteria that can lead to disease; their spatial arrangement also matters. When scientists examined the bacteria that causes tooth decay, they found it 'shields' itself under blankets of sugars and other bacteria in a crown-like arrangement, helping it evade antimicrobials and concentrate its tooth-damaging acids.
Researchers have taken a close look at the flow of materials that have both liquid-like and solid-like states, such as toothpaste, mayonnaise, and ketchup, using both simulations and experiments.
After examining a dozen types of suns and a roster of planet surfaces, astronomers have developed a practical model - an environmental color ''decoder'' - to tease out climate clues for potentially habitable exoplanets in galaxies far away.
Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according to new research. Targeting those pathways via deep brain stimulation may stymie aggression associated with post-traumatic stress disorder.
A quirk in how the brain processes faces makes it harder to tell members of a racial outgroup apart, according to new research.
To break through a looming bandwidth bottleneck, engineers are exploring some of light's harder-to-control properties. Now, two new studies have shown a system that can manipulate and detect one such property: orbital angular momentum. Critically, they are the first to do so on small semiconductor chips and with enough precision that it can be used as a medium for transmitting information.
A research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It's located in an area where few people would have thought to look for an anti-pain center, the amygdala, which is often considered the home of negative emotions and responses, like the fight or flight response and...
A new study reveals clear evidence highlighting the importance of fish biodiversity to the health of spectacular tropical coral reef ecosystems. However, the study's results show that even though strong relationships between diversity and a healthy ecosystem persist, human-driven pressures of warming oceans and invasive species still diminish ecosystems in various ways.
A squad of climate-related factors is responsible for the massive Australian coral bleaching event of 2016. If we're counting culprits: it's two by sea, one by land.
Researchers identify three distinct cortical representations that develop independent of visual experience but undergo experience-dependent reshaping, an essential part of cortical network alignment and maturation.
The construction sector accounts for a quarter of carbon dioxide emissions, in Sweden and globally. Researchers studied the construction of an eight km stretch of road and calculated how emissions could be reduced now and by 2045, looking at everything from materials choice, production technology, supply chains and transport.
Physicists described a route to design the energy-efficient generation, manipulation and detection of spin currents using nonmagnetic two-dimensional materials. The research team observed highly efficient charge-to-spin interconversion via the gate-tunable Rashba-Edelstien effect (REE) in graphene heterostructures.
Scientists know that extreme heat has a negative impact on the human body -- causing distress in the respiratory and cardiovascular systems -- and they know that extreme air pollution can also have serious effects. But as climate change impacts continue globally, how often will humans be threatened by both of those extremes when they occur simultaneously?
The immune system's ability to marshal specialized cells to fight off infection relies in part on tiny molecules called microRNAs, which act as a release for the 'brakes' that keep cells dormant until needed, according to a new study.
Biologists have learned animals can alert future offspring of dangers they will encounter when born. In studies with roundworms and mouse cells, researchers showed how mothers pass chemical signals to their unfertilized eggs, where the warning is stored in the egg cells and passed to offspring after birth.
Despite physical distance, it's possible to create proximity between family members located in different places. This is according to a study that has investigated how video calls bring family members together. The results show that proximity in video calls is established mainly by way of the body and the senses, e.g. by giving a digital high five.
An accumulation of an unexpected intermediate of the peptidoglycan recycling pathway that is able to modulate the synthesis and structure of the cell wall, has been found.
