#Scientists finetune odds asteroid hitting earth series# Trees store records of atmospheric activity in their annual 'growth rings' as they age. The researchers studied the rings of some ancient trees. In this case, New Zealand's kauri trees were studied, which have been preserved in sediments for over 40,000 years and were alive during Adam's Event. The Carbon-14 isotope, or radiocarbon, is rarely found in nature in large quantities. Guided by the spike in radiocarbon levels some 40,000 years ago, scientists were able to date and measure the rise in atmospheric radiocarbon from the collapse of Earth’s magnetic field. While it was known the magnetic poles had temporarily flipped around 41 or 42,000 years ago in an event called the ‘Laschamps Excursion’, scientists were not aware how it had impacted life on the planet, if at all, the statement continued.Īfter ascertaining the time window of Adams event, the team compared the changes seen in the climate across the world during the same time. They found that megafauna across mainland Australia and Tasmania went through simultaneous extinctions 42,000 years ago. Also, the researchers believe that the event could explain the extinction of Neanderthals and the sudden appearance of art in caves around the globe.The logo of NASA’s Frontier Development Lab. NASA’s Frontier Development Lab (FDL) is pioneering a new approach, however, which could dramatically improve our chances of responding to a threatening object hurtling toward us. We’ve turned to artificial intelligence and machine learning–in essence, teaching a computer how to learn by itself, so that it becomes better and better at a set task without needing a human programmer to fine-tune it. #Scientists finetune odds asteroid hitting earth how to# It’s not the all-encompassing AI Skynet from the Terminator movie series, but it’s along the same lines. #Scientists finetune odds asteroid hitting earth movie# Just ignore all that business with the nuclear bombs and time travel. Similar methods are being used in almost every field, often with striking success–from diagnosing cancer patients more quickly in hospitals, to predicting future human behavior from video clips in AI labs and from companies like Apple, which are making personal-assistant AIs more intuitive and helpful than ever before, to improving real-time translation with services like Google Translate.
