Philadelphia to end mask mandate, days after...

PHILADELPHIA (AP) — Philadelphia is ending its indoor mask mandate, city health officials said Thursday night, abruptly reversing course just days after city residents had to start wearing masks again amid a sharp increase in infections. The Board of Health voted Thursday to rescind the mandate, according to the Philadelphia health department, which released a statement that cited “decreasing hospitalizations and a leveling of case counts.” The mandate went into effect Monday. Philadelphia had ended its earlier indoor mask…

Kauai's 2018 record-setting rain caused by a...

A record-setting rainstorm over Kaua’i, Hawai’i in April 2018 resulted in severe flash flooding and estimated damage of nearly $180 million. The deluge damaged or destroyed 532 homes, and landslides left people along Kaua’i’s north coast without access to their homes. In a recently published study, atmospheric scientists at the University of Hawai’i at Manoa revealed that severe supercell thunderstorms were to blame. The rainstorm inundated some areas with nearly 50 inches of rainfall in a 24-hour period, smashing…

The Triumphant Story of Britain's Desi Pubs

Despite being a long walk from a high street in outer West London, The Scotsman is very busy for a drab Monday lunchtime. Before I open the door, I hear loud voices and music, at odds with its austere-looking Edwardian exterior. I pause, wondering what welcome I, a brown drinker, will receive in a locals’ pub unfamiliar to me. I needn’t have worried. Two old Asian boozers glued to their barstools nod when I approach, and the brown bartender……

Monkeys Love Their Alcohol

In 1990, biologist Robert Dudley was enjoying a beer on a wide veranda overlooking a dense rainforest canopy. It had been a long, hot day on Barro Colorado Island, a six-square-mile landmass in the Panama Canal that’s become one of the world’s most researched rainforests thanks to the Smithsonian Tropical Research Institute there. Dudley was there to study insects, but that afternoon he was thinking about monkeys. As he sipped his beer and looked out at the spider monkeys……

Strengthening students’ knowledge and experience in climate...

Tackling the climate crisis is central to MIT. Critical to this mission is harnessing the innovation, passion, and expertise of MIT’s talented students, from a variety of disciplines and backgrounds. To help raise this student involvement to the next level, the MIT Climate and Sustainability Consortium (MCSC) recently launched a program that will engage MIT undergraduates in a unique, year-long, interdisciplinary experience both developing and implementing climate and sustainability research projects. The MCSC Climate and Sustainability Scholars Program is……

Walthamstow Market in London, England

The distinction between the superlatives of a place being the largest or the longest may seem a bit pedantic. But in cases like that of Walthamstow Market, it is still an important one. While the largest outdoor market in Europe might be The Hague’s Haagse Mart, Walthamstow Market takes great pride in its title as possibly the longest. While often said to occupy a mile of this neighborhood’s High Street, its actual length is in fact closer to a……

A new state of the art for...

Labeling data can be a chore. It’s the main source of sustenance for computer-vision models; without it, they’d have a lot of difficulty identifying objects, people, and other important image characteristics. Yet producing just an hour of tagged and labeled data can take a whopping 800 hours of human time. Our high-fidelity understanding of the world develops as machines can better perceive and interact with our surroundings. But they need more help. Scientists from MIT’s Computer Science and Artificial……

Anticipating others’ behavior on the road

Humans may be one of the biggest roadblocks keeping fully autonomous vehicles off city streets. If a robot is going to navigate a vehicle safely through downtown Boston, it must be able to predict what nearby drivers, cyclists, and pedestrians are going to do next. Behavior prediction is a tough problem, however, and current artificial intelligence solutions are either too simplistic (they may assume pedestrians always walk in a straight line), too conservative (to avoid pedestrians, the robot just……

“Spring-loaded” system pops phosphorus into molecular rings

MIT chemists have devised a new chemical reaction that allows them to synthesize a phosphorus-containing ring, using a catalyst to add phosphorus to simple organic compounds called alkenes. Their reaction, which yields a ring containing two carbon atoms and one phosphorus atom, can be performed at normal temperature and pressure, and makes use of a novel “spring-loaded” phosphorus-containing molecule that supplies the phosphorus atom. “This is a rare example of a discovery of a new catalytic reaction, and it……

BOSTON (AP) — Celtics fans got under Kyrie Irving’s skin in the opening game of their first-round matchup with the Nets.

This Challah is Key to Good Fortune...

When Rochel Schulgasser asks her neighbor Nava to bring over a house key each spring, it isn’t because Nava needs daffodils watered or a repairman let in. It’s always right after Passover, so it’s not like Nava has gone out of town and needs someone to housesit her home in Passaic, New Jersey. Instead, Schulgasser asks for her neighbor’s key so that she can bake it inside a challah bread. You know, as one does. Each year, on the……
