A team of researchers working at Stanford University has used time dilation in an atomic fountain to measure the curvature of space-time. In their study, reported in the journal Science, the group used the fountain as an ...
A new study led by researchers from McGill University and INRAE found that between 51-60% of the 64 million kilometres of rivers and streams on Earth that they investigated stop flowing periodically, or run dry for part of ...

The enzyme nitrogenase is a biological catalyst that can reduce dinitrogen (N2) to ammonia in the presence of a suite of complex metallocofactors. However, the mechanistic details of the reaction remain scarce. In a new report ...
A new study conducted by French astronomers has delivered new insights about central stellar population and gas outflow in the spiral galaxy NGC 1068. Results of the research, presented in a paper published May 22 on arXiv.org, ...
A pair of researchers, one with the Langevin Institute, the other a company called Greenerwave, both in France, has developed a way to use ordinary Wi-Fi signals to perform analog, wave-based computations. In their paper ...
A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported ...
