Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

A new study shows that sound isn’t just heard by the ears. Sound waves altered gene expression and influenced fat cell differentiation in culture. Kumeta wanted to know if the changes in gene ...
