 Bones of MammothsN Mexico City

Last year, archaeologists discovered huge earthen pits dug by humans some 15,000 years ago in an area just north of Mexico City. Inside those pits were the remains of more than a dozen woolly mammoths, some of which showed signs of being butchered. This discovery led researchers to hypothesize that these pits were in fact traps laid by human ancestors to capture huge, prehistoric prey. In 2020,  another mammoth graveyard has been found just six miles away, though archaeologists so far see no signs of human involvement in the demise of the roughly 60 mammoths that have been unearthed.

Autism and the Israeli Army

Six years ago, three former Mossad agents launched an experimental Israeli Army program to recruit those on the autism spectrum, harnessing their unique aptitudes—their "superpowers," as one soldier puts it. The name of this big military success? Roim Rachok, Hebrew for "seeing into the future," and it may bring neurodiversity to the broader workforce. They’re part of an innovative military program called Roim Rachok, Hebrew for “seeing into the future.” The elite group consists entirely of members of a burgeoning but underserved and overlooked population with powers as special as their needs: autistic teens.

There were folks dressed in lab coats and pink knit brain hats. There were costumed characters and festooned pets. And there were many, many signs. Across the nation and abroad, as thousands of scientists and their supporters convened on Earth Day to defend science against proposed government cuts and political interference, many got their messages across with colorful and candid protest signs.  Here are some of the best signs we have seen

5G is innovating medicine—connecting surgeons with patients in understaffed hospitals in remote parts of the world and providing a seamless surgical experience for telesurgery. The surgery itself was old hat for Dr. Patel. As Chief Interventional Cardiologist at the Apex Heart institute in Ahmedabad, Patel had performed countless coronary angioplasties, a surgery where a balloon is inserted into the arteries of the heart and inflated to widen the artery and increase blood flow. A small mesh tube, called a stent, is then placed in the artery to keep it from narrowing again.

 Popo August 2019 Eruption

Scientific examinations of historical accounts suggest that up to 40 percent of Mexico’s population lives along a zone that is more seismically active than suspected. Ash spews from Mexico's Popocatépetl volcano in August 14, 2019 (see above photo). The peak is part of the Trans-Mexican Volcanic Belt, a region which seismologists say may present a greater earthquake hazard than anticipated. According to the Anales de Tlatelolco, the earth cracked open in central Mexico on February 19, 1575. The ancient codex, composed around the time the Aztec Empire fell to Spanish conquistadors, features a story of a convulsion that lasted for up to five days, creating landslides and opening up a nearly three-mile-long scar in the ground.
