Free and unimpeded internet access is no longer a convenience or a luxury. It is high time it was made a human right enshrined in law, says philosopher Merten Reglitz

Rearing our unusually underdeveloped young may account for the evolution of language. Michael Marshall is intrigued, but wants more evidence from Madeleine Beekman's The Origin of Language

Psychiatric medicine hasn't changed much since the 1960s. Could blocking the effects of chronic inflammation on the brain be the step change we need?

Battlestar Galactica meets FTL in this just-announced "story-rich tactical roguelite" from the makers of Crying Suns.

Russia launched its Bion-M No. 2 biosatellite today (Aug. 20), sending 75 mice, 1,000 fruit flies and other organisms to orbit to learn more about the health effects of spaceflight.

A fireball exploded into life in the skies above Japan on Aug. 19, briefly turning night to day before fragmenting close to the horizon.

Viking 1 was launched by a Titan-Centaur rocket from Complex 41 at Cape Canaveral Air Force Station at 5:22 p.m. EDT on Aug. 20, 1975, to begin a half-billion mile, 11-month journey through space to explore Mars. The 4-ton spacecraft went into orbit around the red planet in mid-1976 and landed on Mars on July 20, 1976.

A Titan-Centaur rocket carrying the Viking 1 spacecraft launches from Complex 41 at Cape Canaveral Air Force Station on Aug. 20, 1975. Viking 1 touched down on the red planet on July 20, 1976, becoming the first truly successful landing on Mars. Viking 1 was the first of a pair of complex deep space probes that were designed to reach Mars and to collect evidence on the possibility on life on Mars.

NASA’s exploration of Mars continues, with rovers exploring the planet’s surface and spacecraft studying from orbit. The agency’s Artemis missions will also lay the groundwork for the first crewed missions to Mars.

A 1989 experiment offered the promise of nuclear fusion without the need for high temperatures, but this "cold fusion" was quickly debunked. Now, some of the techniques involved have been resurrected in a new experiment that could actually improve efforts to achieve practical fusion power
