Record-breaking neutrino detected by huge underwater telescope

In this episode:

00:45 An elusive, cosmic neutrino with a record-breaking energy

An enormous array of detectors, deep under the Mediterranean Sea, has captured evidence of the highest-energy neutrino particle ever recorded, although researchers aren’t sure exactly where in the cosmos it originated. Calculations revealed this particle had over 30 times the energy of previously detected neutrinos. The team hopes that further study and future detections will help reveal the secrets of high-energy phenomena like supernovae.

14:15 US judge puts NIH grant cuts on hold

A judge has blocked a policy that would have slashed billions of dollars of funding for US research institutions, which come as part of President Donald Trump’s controversial crackdown on government spending. We discuss the reasoning behind the proposed cuts and the impacts they may have if enacted. We also look at the effects that President Trump’s executive orders targeting diversity, equity and inclusion (DEI) policies and funding are having across the US.
