Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new UCL-led research.
Predicted by Einstein’s general theory of relativity, gravitational waves are ripples in space–time generated by certain movements of massive objects. They are important to study because they allow us to detect events in the universe that would otherwise leave little or no observable light, like black hole collisions.

The origin of our teeth goes back more than 400 million years back in time, to the period when strange armored fish first developed jaws and began to catch live prey. We are the descendants of these fish, as are all the other 60,000 living species of jawed vertebrates — sharks, bony fish, amphibians, reptiles, birds and mammals. An international team of scientists led by Uppsala University (Sweden), in collaboration with the ESRF, the European Synchrotron (France), the…
Report Finds Police Use-of-Force Policies Fall Short of Human Rights Standards
Law School scholars: Police departments in 20 largest U.S. cities fail to meet basic principles.
Police use-of-force policies in the nation’s 20 largest cities fail to meet international human rights standards, according to a new report from the University of Chicago Law School.
Let's face it: we know almost nothing about the universe. Sure, we've got some things nailed down: we know about the existence of dark matter and dark energy. We know about the Big Bang. We know how galaxies form over the course of billions of years. And most painfully of all, we know that "normal" matter (the kind of matter that makes stars, galaxies, planets and you) is no more than 5% of all the mass and energy in the universe.

Lucky skywatchers across the world are currently able to see a newly discovered comet, dubbed Comet C/2020 F3 NEOWISE at predawn. This comet NEOWISE will reach its maximum point in the dawn sky on July 11 before disappearing below the horizon. But there's some good news for skywatchers, especially for the ones living India as they'll be able to see the comet right after sunset between July 12-15 with just a pair of binoculars or even with their naked eyes. It will make its closest approach to Earth on July 22-23, passing just over 10 crore kilometres from us.
