Sold: A $44,000 Doghouse With a Hole...

On April 23, 2019, at 9:07 PM, a meteorite struck a doghouse in rural Costa Rica. The doghouse’s resident at the time, a German shepherd named Rocky, was soundly asleep inside when the 69-pound space rock came flying through his rusty tin roof. The meteorite just barely missed the lounging Rocky, leaving a gaping seven-inch hole in its wake and destroying the doghouse’s weathered wooden floor. Professional meteorite hunters were on the scene almost immediately, having watched satellite images……

How to reach a tumbling target in...

In 2002, the European Space Agency launched Envisat, the largest civilian satellite (at the time) to go to low Earth orbit (LEO). For a decade, it observed our planet and sent back valuable data on Earth’s climate, tracking the decline of Arctic sea ice and more, until it went dark in 2012. One of the prevailing theories for its demise is that it simply ran out of fuel. As LEO becomes more crowded, Envisat is a school bus-sized example……

Whimsy and alkene isomerization in the Wendlandt...

Isomers are compounds that share identical chemical formulae but differ in structure or configuration, affecting their physical and chemical properties. A common example is glucose and fructose; both isomers of C6H12O6 are metabolized differently by our bodies due to a different arrangement of the same atoms. The process of transforming a compound into any of its isomers is called isomerization. This important tool allows scientists to access molecules that are not easily obtained, such as certain alkenes, which are……

Monson Steps in St. Augustine, Florida

Dr. Martin Luther King, Jr. was arrested on these steps in 1964. Charged with trespassing, his “crime” was attempting to join friends for lunch. The Monson Motor Lodge & Restaurant was a “Whites only” establishment. From a jail cell, King wrote to Rabbi Israel Dresner encouraging him to speak out against local injustice. This was also the scene of an infamous hate crime, when a motel owner poured acid into a swimming pool full of anti-segregationists. Both incidents made……

Old Mosque in Chinguetti, Mauritania

Visitors to Chinguetti have the chance to see new Chinguetti, where most accommodations are located, and old Chinguetti, the semi-abandoned, half-buried city where ancient libraries can be found. There is, however, a third Chinguetti, which has almost entirely been reclaimed by the desert. A little over one mile (two kilometers) northeast of modern Chinguetti, on the way to the village of Entkemkemt, the desert track runs through a set of unimpressive sand dunes. Buried under these sand dunes are……

Shepherdstown Public Library in Shepherdstown, West Virginia

Though it is now a library, this small white building in Shepherdstown, West Virginia, has had a number of other uses over the last 200 years.

'Inscription of the Island' in Singapore

In this sculpture at Changi Beach Park, artist Lim Soo Ngee imagines what the monumental relics of Bronze Age Singapore might look like. Taking inspiration from the Colossus of Rhodes, Lim envisioned a statue that stood by the Kingdom of Singapura’s trade routes, stretching out a finger to act as a sundial and guiding vessels from all around the region into Singapura’s port. Like much of classical Singapore’s history, the bulk of the imagined Colossus had since been lost,……

Point Breeze Estate in Bordentown, New Jersey

Born and raised amid the natural beauty of the Dominican Republic, Andrés Bisonó León feels a deep motivation to help solve a problem that has been threatening the Caribbean island nation’s tourism industry, its economy, and its people. As Bisonó León discussed with his long-time friend and mentor, the Walter M. May and A. Hazel May Professor of Mechanical Engineering (MechE) Alexander Slocum Sr., ugly mats of toxic sargassum seaweed have been encroaching on the Dominican Republic’s pristine beaches……

Using artificial intelligence to find anomalies hiding...

Identifying a malfunction in the nation’s power grid can be like trying to find a needle in an enormous haystack. Hundreds of thousands of interrelated sensors spread across the U.S. capture data on electric current, voltage, and other critical information in real time, often taking multiple recordings per second. Researchers at the MIT-IBM Watson AI Lab have devised a computationally efficient method that can automatically pinpoint anomalies in those data streams in real time. They demonstrated that their artificial……
