Since then, Sophia has spoken to audiences across the globe (in multiple languages), been interviewed on countless TV shows, and even earned a United Nations title (a first for a non-human).

Today, she’s arguably the most famous robot in the world, but she’s isn’t going to be unique for much longer. Her maker, Hanson Robotics, has announced plans to begin mass-producing Sophia the robot this year — so that she can help the world cope with the pandemic.

If everything goes to plan, Webb will remake astronomy by peering at cosmic phenomena such as the most distant galaxies ever seen, the atmospheres of far-off planets and the hearts of star-forming regions swaddled in dust. Roughly 100 times more powerful than its predecessor, the Hubble Space Telescope, which has transformed our understanding of the cosmos over the past 31 years, Webb will reveal previously hidden aspects of the Universe.

Three decades after it was conceived, Hubble’s successor is set for launch. Here’s why astronomers around the world can’t wait.

NASA is getting out LEO — and letting private companies take its place.

NASA recently announced conctracts for three new space stations, all of them designed and built by private space companies. NASA is getting out LEO.

An artificial leaf converts water and light to oxygen, and that’s good news for road-tripping to places beyond Earth.

“If we’re going to use scrap aluminum for hydrogen generation in a practical application, we need to be able to better predict what hydrogen generation characteristics we’re going to observe from the aluminum-water reaction,” says Laureen Meroueh PhD ’20, who earned her doctorate in mechanical engineering.

Since the fundamental steps in the reaction aren’t well understood, it’s been hard to predict the rate and volume at which hydrogen forms from scrap aluminum, which can contain varying types and concentrations of alloying elements. So Hart, Meroueh, and Thomas W. Eagar, a professor of materials engineering and engineering management in the MIT Department of Materials Science and Engineering, decided to examine — in a systematic fashion — the impacts of those alloying elements on the aluminum-water reaction and on a promising technique for preventing the formation of the interfering oxide layer.

To prepare, they had experts at Novelis Inc. fabricate samples of pure aluminum and of specific aluminum alloys made of commercially pure aluminum combined with either 0.6 percent silicon (by weight), 1 percent magnesium, or both — compositions that are typical of scrap aluminum from a variety of sources. Using those samples, the MIT researchers performed a series of tests to explore different aspects of the aluminum-water reaction.

Shifts in polar weather have accompanied the replenishment of the ozone layer.

As Russia ramps up preparations for a possible assault on Ukraine, President Biden has ruled out sending U.S. troops, but an invasion would still face serious resistance and Ukraine’s defense minister promising a ‘bloody massacre’ if Russia invades. While Ukraine is heavily outmatched by Russian forces, the threat of heavy casualties is one which Russian cannot ignore. This is why uncrewed systems – remote-controlled robot warriors – could play an important part where the fighting is heaviest.

Soviet Russia shrugged off mass casualties, with Stalin remarking, “One death is a tragedy; a million deaths is a statistic.” During World War II – the Great Patriotic War to Russians – the Soviet Union lost more than 8 million members of its armed forces, 20 times as many as the United States. Names like Stalingrad became legendary for bloody battles and tough resistance regardless of casualties.

Modern Russia is very different. Unlike Stalin, President Putin cannot ignore public opinion, and his media machine will hide or deny Russian casualties in foreign operations. Mercenaries are increasingly used to keep conflict at arm’s length, as the loss of contractors does not play so badly in the motherland.

According to a news release by The University of Manchester, a groundbreaking study published in the journal Scientific Reports provides new evidence that helps us to understand the asteroid impact that brought an end to 75 percent of life on Earth, including non-avian dinosaurs, at the Cretaceous-Paleogene transition 66 million years ago.

This project has been a huge undertaking but well worth it. For so many years we’ve collected and processed the data, and now we have compelling evidence that changes how we think of the KPg event, but can simultaneously help us better prepare for future ecological and environmental hazards.

Time of year plays an important role in many biological functions— reproduction, available food sources, feeding strategies, host-parasite interactions, seasonal dormancy, breeding patterns, to name a few. It is hence no surprise that the time of year for a global-scale disaster can play a big role in how harshly it impacts life. The seasonal timing of the Chicxulub impact has therefore been a critical question for the story of the end-Cretaceous extinction. Until now the answer to that question has remained unclear.
