三管齐下的方法辨别量子自旋液体的性质

In 1973, physicist Phil Anderson hypothesized that the quantum spin liquid, or QSL, state existed on some triangular lattices, but he lacked the tools to delve deeper. Fifty years later, a team led by researchers associated with the Quantum Science Center

土壤中的微塑料:中子和X射线层析成像显示颗粒沉积的位置

It is a real problem: Microplastic particles are everywhere. Now a team from the University of Potsdam and HZB has developed a method that allows it for the first time to precisely localise microplastic particles in the soil. The 3D tomographies show wher

结束塑料分离焦虑

Bio-based plastics such as polylactic acid (PLA) were invented to help solve the plastic waste crisis, but they often end up making waste management more challenging. Because these materials look and feel so similar to conventional, petroleum-based plasti

人工智能发现如何预测巨浪的公式

Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years' worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Victoria

清除二战弹药的爆炸可能会污染海洋

World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but con

“白云石问题”:200年地质之谜解开

For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, a team of researchers from the University of Michigan and Hokkaido University in Sapporo, Japan have finally p

分离海底记录的信号

Blame it on plate tectonics. The deep ocean is never preserved, but instead is lost to time as the seafloor is subducted. Geologists are mostly left with shallower rocks from closer to the shoreline to inform their studies of Earth history.
