The reasons behind lithium-ion batteries’ rapid cost...

Lithium-ion batteries, those marvels of lightweight power that have made possible today’s age of handheld electronics and electric vehicles, have plunged in cost since their introduction three decades ago at a rate similar to the drop in solar panel prices, as documented by a study published last March. But what brought about such an astonishing cost decline, of about 97 percent? Some of the researchers behind that earlier study have now analyzed what accounted for the extraordinary savings. They……

Rittenhouse acquittal tightens the political vise for...

WILMINGTON, Del. (AP) — A difficult political atmosphere for President Joe Biden may have become even more treacherous with the acquittal of Kyle Rittenhouse. Biden was already facing sliding poll numbers with an electorate worn down by the coronavirus pandemic and increasing inflation. Now, the president finds himself caught between outraged Democrats — some of whom were already stewing over Biden’s inability to land police reform and voting rights legislation — and Republicans looking to use the Rittenhouse case…

5 Recipes From Indigenous Chefs to Add...

The modernized version of the Thanksgiving holiday is a blend of myth and fact. Although Plymouth Pilgrims did celebrate the harvest with members of the local Wampanoag tribe in 1621, a holiday called Thanksgiving wasn’t celebrated until the 1830s and wasn’t made official until 1863. By that point, European colonizers had committed countless atrocities against Indigenous communities, casting a dark shadow over the cross-cultural bread-breaking associated with the holiday. Instead of leaning into rosy, revisionist history, why not use……

A Photographer's Journey With the Ancient Baobabs...

When Tsitakakoike, one of the largest Grandidier’s baobab trees in Madagascar, with a circumference of almost 90 feet, split and collapsed in 2018 after years without rain, it was a huge loss. Not only are the fruit and bark of this species, also known as the “mother of the forest,” useful as food and rope-making material, but Tsitakakoike was estimated to be 1,400 years old and sacred to the residents of nearby Andombiro village. The villagers believed that the……

Design’s new frontier

In the 1960s, the advent of computer-aided design (CAD) sparked a revolution in design. For his PhD thesis in 1963, MIT Professor Ivan Sutherland developed Sketchpad, a game-changing software program that enabled users to draw, move, and resize shapes on a computer. Over the course of the next few decades, CAD software reshaped how everything from consumer products to buildings and airplanes were designed. “CAD was part of the first wave in computing in design. The ability of researchers……

Emiliano Zapata House Museum in Anenecuilco, Mexico

In front of a striking mural at the center of the sun-baked town of Anenecuilco stands the ruins of a house in which the iconic revolutionary Emiliano Zapata was born and grew up. Born in 1879 to a mestizo (mixed Indigenous and Spanish ancestry) and campesino (rural peasant) family, Zapata was orphaned at a young age. His early life was marked by misery, poverty, and exposure to the brutality and injustice of the hacienda system.  At the time, Mexico‘s hacienda system……

Cappella Suardi in Trescore Balneario, Italy

Cappella Suardi is an ordained place of worship that belongs to a private individual. The chapel itself is surprisingly small – just over nine meters in length and four meters in wide. Already in existence in the 15th-century, the chapel was located on a major artery connecting Bergamo to the rest of Europe. To appreciate the themes in the fresco, it is necessary to contextualize them in historical terms. The 16th-century was characterized by the turmoil caused by the……

Armstrong Tunnel in Pittsburgh, Pennsylvania

Running underneath the Bluff in Pittsburgh, Pennsylvania, there is a twin-bore tunnel with an unusual feature: a 45-degree bend near the northern portal. Built between 1926 and 1927, the Armstrong Tunnel was named after Joseph Armstrong, former County Director of Public Works, Commissioner, and Mayor of Pittsburgh.

A stealthy way to combat tumors

Under the right circumstances, the body’s T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor.  Scientists are now trying to find ways to help treat patients by jumpstarting those lackluster T cells. Much of the research in this field, known as cancer immunotherapy, has focused on finding ways to stimulate those T cells directly. MIT researchers have now uncovered a possible new way……

Tennessee governor’s aide warned new COVID law...

NASHVILLE, Tenn. (AP) — Tennessee Gov. Bill Lee’s office warned lawmakers that their sprawling bill limiting COVID-19 restrictions would violate federal law that protects people with disabilities and put the state at risk of losing federal funds, according to records obtained by The Associated Press. The Republican-controlled Legislature ignored the advice and passed the bill anyway. Less than two weeks later, the Republican governor signed it into law. Lee, who is up for reelection next year, has since said…

How to Find ‘Comets’ and Other Wonders...

Alexey Korolyov has some strong feelings about where to find wonder. “I am absolutely sure you do not need to travel far distances to capture a once-in-a-lifetime shot,” says Korolyov, a photographer based in Russia. “Just around the corner you can find inspiration.” Korolyov’s Instagram is full of unexpected close-ups that play with expectations: Frosty clumps of fallen leaves look like a satellite image of snow-dusted mountains, and stands of trees beside a pond transform into an Impressionist painting…….

Falls of Leny in Kilmahog, Scotland

The Falls of Leny are a series of cascading waterfalls that force their way through a narrow gorge before tumbling down the boulder-strewn ravine.

They occur where the river crosses the Highland Boundary Fault. The name Leny may be of Gaelic origin, and it is thought to have derived from the word……

Duino Mithraeum in Duino, Italy

A short drive west from Trieste and just above the town of Duino, in the Italian region of Friuli-Venezia Giulia, there is a Roman Mithraeum that dates to the first century B.C. A Mithraeum is a temple sacred to those who worshipped the god Mithras and followers of the Mithraic mysteries. Most Mithraeae are found in what was the Ancient Roman Empire.
