Rapidly Melting Permafrost Has Tipped the Arctic Into Being a Net Greenhouse Gas Emitter
Global warming’s disproportionate effect on the planet’s polar regions has turned the Arctic into a net carbon emitter, with one-third of the region’s forests, tundra and wetlands now emitting more greenhouse gases than they absorb as the previously-frozen permafrost thaws. “It is the first time that we’re seeing this shift
‘Age Against the Machine’: Like Humans, AI Suffers Cognitive Decline as it Ages
One of the strengths of artificial intelligence is that the structure of the coded neural nets that make machine learning possible is based on the layout of the neurons of our own brains, a branching, neurological-like network capable of learning from trial and error. However, a new study has discovered
A Long-Lost Interview Details Albert Einstein’s Involvement with the Roswell UFO Crash
As part of their attempt to address the puzzle presented by the debris and bodies recovered from the 1947 UFO crash at Roswell, New Mexico, the U.S. government enlisted the expertise of renowned theoretical physicist Albert Einstein, according to a previously-lost interview with a student aide who claims to have accompanied
‘City-Killer’ Asteroid has a Small—but Non-Zero—Risk of Striking Earth in 2032
A sizable “city-killer” asteroid that was discovered late last year has been calculated to have a one in 77 chance of striking the Earth just eight years from now, according to NASA’s Jet Propulsion Laboratory. Although the chance of impact is still very low, the object’s higher than one
The Sun is Expected to Enter a ‘Battle Zone’ After the Crescendo of Solar Maximum
The Sun will soon enter a so-called ‘battle zone’ phase that is expected to follow this solar cycle’s maximum, according to newly-formed space weather prediction company Lynker Space. Although this phase stabilizes the swarm of magnetic fields across the surface of the Sun, it also increases the chance that large
