Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid particles are evenly distributed. If the concentration of particles in such a mixture is very high, phenomena can be observed that contradict our everyday understanding of…
When U.S. President Donald Trump imposed sweeping new tariffs on imported goods on April 2, 2025—upending global trade and sending markets into a tailspin—he presented the move as a response to a crisis. In an executive order released the same day, the White House said the move was necessary to address “the national emergency posed…
Research teams from USTC have realized a high-performance single-photon source with an efficiency beyond the scalable linear optical quantum computing loss tolerance threshold for the first time. Led by Prof. Pan Jianwei, Lu Chaoyang and Hu Yongheng, the study was published in Nature Photonics on February 28. Research teams from USTC have realized a high-performance single-photon…
According to researchers, debates about diversity programs in companies and public institutions, and the question of how to deal with social diversity, are often oversimplified.

The winter growth period for sea ice in the Arctic Ocean is now over, with levels at a record low. The winter ice extent on 21 March 2025 was lower than at any time since continuous satellite recording began in 1979. The winter growth period for sea ice in the Arctic Ocean is now over, with…
There are trillions of microplastic particles, ranging in size from about one micrometer to a few millimeters, on Earth. Many of these particles end up in the oceans, where they disrupt nutrient cycles, are ingested by marine animals or transport pollutants. To better understand how microplastics accumulate and disperse in marine environments, new research published…
A mission will deliver rock and soil from Mars to laboratories on Earth in the 2030s. Mars Sample Return (MSR) is led by NASA with participation from the European Space Agency (ESA). The mission will allow scientists to use the best laboratory instruments on Earth to determine whether Mars hosted microbial life billions of years…
Can your accent make you sound aggressive? Exeter City football manager Gary Caldwell thinks so—he blamed his Scottish accent for his being sent off the pitch for the second time this season.

The problem of the disadvantage gap—also known as the attainment gap—is a persistent one in education in England. It refers to how children from certain groups, such as those from poorer backgrounds, ethnic minorities or who have been in care, do worse at school than their peers. The problem of the disadvantage gap—also known as the…
For the better part of a century, the quantum objects known as quasiparticles have been all dressed up with nowhere to go. But that may change, now that a Yale-led team of physicists has shown it is possible to exert a greater level of control over at least one type of quasiparticle. For the better part…
