Empowering kids to address Covid-19 through coding

When schools around the world closed their doors due to the coronavirus pandemic, the team behind MIT App Inventor — a web-based, visual-programming environment that allows children to develop applications for smartphones and tablets — began thinking about how they could not only help keep children engaged and learning, but also empower them to create new tools to address the pandemic. In April, the App Inventor team launched a new challenge that encourages children and adults around the world……

Engineers design a reusable, silicone rubber face...

Researchers at MIT and Brigham and Women’s Hospital have designed a new face mask that they believe could stop viral particles as effectively as N95 masks. Unlike N95 masks, the new masks were designed to be easily sterilized and used many times. As the number of new Covid-19 cases in the United States continues to rise, there is still an urgent need for N95 masks for health care workers and others. The new mask is made of durable silicone……

To engineers’ surprise, radiation can slow corrosion...

Radiation nearly always degrades the materials exposed to it, hastening their deterioration and requiring replacement of key components in high-radiation environments such as nuclear reactors. But for certain alloys that could be used in fission or fusion reactors, the opposite turns out to be true: Researchers at MIT and in California have now found that instead of hastening the material’s degradation, radiation actually improves its resistance, potentially doubling the material’s useful lifetime. The finding could be a boon for……

Virus projects renew questions about UAE’s mass...

DUBAI, United Arab Emirates (AP) — Efforts by the United Arab Emirates to fight the coronavirus have renewed questions about mass surveillance in this U.S.-allied federation of seven sheikhdoms. Experts believe the UAE has one of the highest per capita concentrations of surveillance cameras in the world. From the streets of the capital of Abu Dhabi to the tourist attractions of skyscraper-studded Dubai, the cameras keep track of the license plates and faces of those passing by them. While…

Coinbase reported to consider late 2020, early...

Coinbase is the latest mega-startup that may approach the public markets. The digital currency exchange company could follow Palantir, which is also nearing its IPO, after the secretive data-focused unicorn announced that it had filed privately. Earlier today Reuters reported that Coinbase, a popular American-based cryptocurrency trading platform, could pursue a public debut later this year, or early next year. Plans remain fluid, according to the report, which went on to say that the crypto-focused fintech company “has been……

World’s Largest Working Wooden Yo-Yo in Chico,...

Bird in Hand, a gift shop in downtown Chico, is home to the U.S. National Yo-Yo Museum as well as the largest functioning wooden yo-yo in the world. Modeled after Tom Kuhn’s No-Jive Three-in-One, the gargantuan yo-yo earned its place in the Guinness Book of World Records in 1982 as the world’s biggest working wooden yo-yo. Not even the strongest of yo-yo-tossing humans could take on this four-foot tall, 256-pound toy; only a giant crane has been able to……

Piè di Marmo (Marble Foot) in Rome,...

A colossal marble left foot is tucked at the end of a small alley near the Pantheon in Rome, giving the adjacent street, where it was originally found, its name: Via del Piè di Marmo (Marble Foot Way). The foot is actually four feet long, which has led archaeologists to believe that the complete statue must have been some 25 feet tall. The foot is believed to be a fragment of a colossal statue from the Temple of Serapis……

The Latest: China easing into reopening as...

BEIJING — China says it has nine new confirmed coronavirus cases, all of them brought from outside the country, and no new deaths. Thursday’s report buttresses growing signs the virus has been essentially contained inside the nation in which it first appeared late last year. The near elimination of local virus transmission has allowed the reopening of most businesses and resumption of some social activities, including the holding of the crucial annual college entrance exams. Sports, tourism and cultural…

Flatworms muscle new eyes' wiring into their...

If anything happens to the eyes of the tiny, freshwater-dwelling planarian Schmidtea mediterranea, they can grow them back within just a few days. How they do this is a scientific conundrum — one that Peter Reddien’s lab at Whitehead Institute has been studying for years. The lab’s latest project offers some insight: in a paper published in Science June 26, researchers in Reddien’s lab have identified a new type of cell that likely serves as a guidepost to help route axons……

Europe’s New Mars Yard Is Like a...

Probably never before in the history of the industry has a maker of bridge cranes—the kind that are mounted on a gantry—been asked to slow one of its machines down. There’s a practical reason for that: The machines are usually used in factories and warehouses to move heavy things around and, after all, time is money. But the world of science doesn’t cling to the same view of time. “We contacted the company in charge of the bridge crane……

Found: A Letter From Frederick Douglass, About...

The debate over historical monuments currently roiling the United States is, in fact, nothing new. Back in 1876, none other than Frederick Douglass himself took issue with a Washington, D.C., statue of Abraham Lincoln, which activists are now lobbying to have taken down. Only now, however, do historians have proof of what Douglass thought of it when it went up. The statue in Lincoln Park, known as the Emancipation Memorial, depicts the 16th president beside a Black man who,……

Ghost Town of Rovaiolo Vecchio in Brallo...

Rovaiolo Vecchio is an ancient village in the mountains in the province of Pavia, halfway between Milan and the sea. Or at least it was. Before the construction of highways and railways, the road that passes through the town was of primary importance for the importing of salt to population centers in the Po Valley.  One day in 1960, local officials ordered the immediate evacuation of the whole village: The mountain was sliding down onto it. Within a few……

Archaeology Dogs Can Help Scholars Sniff Out...

This piece was originally published in SAPIENS. On a sunny, cloudless afternoon in Croatia, a fierce wind known as a bora can whip over the Velebit mountain range and across the Adriatic Sea. When it reaches hurricane force, this cold, dry wind can render the steep, arid terrain freezing at midday. This coastal region is dominated by karst, a porous rock topography. Despite the area’s challenging conditions, humans eked out an existence here thousands of years ago. Archaeologist Vedrana……
