Not metaphorically. Not theoretically. Literally, in a lab, on camera, measured to the nanosecond. A team of physicists led by researchers at the Technion-Israel Institute of Technology, working alongside collaborators from Harvard, MIT, and Stanford, has published a landmark study in the journal Nature confirming something physicists have quietly suspected since the 1970s.

We may finally know what first lit up the cosmic dawn in the early Universe.

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space. A paper about the research was published in February 2024.

"This discovery unveils the crucial role played by ultra-faint galaxies in the early Universe's evolution," said astrophysicist Iryna Chemerynska of the Institut d'Astrophysique de Paris.

A landmark study from Oregon State University, published in the peer-reviewed journal Addiction, tracked more than 850,000 college students across 590 campuses over a decade and found that in states where recreational marijuana was legal, students over 21 showed a greater drop in binge drinking than their peers in states where it was not legal.

A study led by researchers at Heidelberg University in Germany surveyed 55,000 people aged 50 and older across 16 European countries and found that parents reported greater life satisfaction and fewer symptoms of depression than people without children, but only under one specific condition: their children had already moved out of the house.
