As soon as upon a time, water flowed throughout the floor of Mars. Waves lapped in opposition to shorelines, sturdy winds gusted and howled, and driving rain fell from thick, cloudy skies. It wasn’t actually so totally different from our personal planet 4 billion years in the past, aside from one essential element—its dimension. Mars is about half the diameter of Earth, and that’s the place issues went unsuitable.
The Martian core cooled rapidly, quickly leaving the planet and not using a magnetic area. This, in flip, left it weak to the photo voltaic wind, which swept away a lot of its ambiance. And not using a important protect from the solar’s ultraviolet rays, Mars couldn’t retain its warmth. Among the oceans evaporated, and the subsurface absorbed the remaining, with solely a little bit of water left behind and frozen at its poles. If ever a blade of grass grew on Mars, these days are over.
However may they start once more? And what wouldn’t it take to develop vegetation to feed future astronauts on Mars? Learn the total story.

This lab robotic mixes chemical substances
Lab scientists spend a lot of their time doing laborious and repetitive duties, be it pipetting liquid samples or operating the identical analyses time and again. However what if they might merely inform a robotic to do the experiments, analyze the info, and generate a report?
Enter Organa, a benchtop robotic system devised by researchers on the College of Toronto that may do precisely that. The system may automate some chemistry lab duties utilizing a mixture of pc imaginative and prescient and a big language mannequin that interprets scientists’ verbal cues into an experimental pipeline. Learn the total story.
