Famed polar explorer Ernest Shackleton famously defied the odds to survive the sinking of his ship, Endurance , which became trapped in sea ice in 1914. His luck ran out on his follow-up expedition; he died unexpectedly of a heart attack in 1922 on board a ship called Quest . The ship survived that expedition and sailed for another 40 years, eventually sinking in 1962 after its hull was pierced by ice on a seal-hunting run. Shipwreck hunters have now located the remains of the converted Norwegian sealer in the Labrador Sea, off the coast of Newfoundland, Canada. The wreckage of Endurance was found in pristine condition in 2022 at the bottom of the Weddell Sea.

The Quest expedition's relatively minor accomplishments might lack the nail-biting drama of the Endurance saga, but the wreck is nonetheless historically significant. "His final voyage kind of ended that Heroic Age of Exploration, of polar exploration, certainly in the south," renowned shipwreck hunter David Mearns, who directed the operation, told the BBC . "Afterwards, it was what you would call the scientific age. In the pantheon of polar ships, Quest is definitely an icon."

As previously reported , Endurance set sail from Plymouth, Massachusetts, on August 6, 1914, with Shackleton joining his crew in Buenos Aires, Argentina. By January 1915, the ship had become hopelessly locked in sea ice, unable to continue its voyage. For 10 months, the crew endured the freezing conditions, waiting for the ice to break up. The ship's structure remained intact, but by October 25, Shackleton realized Endurance was doomed. He and his men opted to camp out on the ice some two miles (3.2 km) away, taking as many supplies as they could with them.

Gamers of a certain age may remember Nintendo's Game & Watch line, which predated the cartridge-based Game Boy by offering simple, single-serving LCD games that can fetch a pretty penny at auction today . But even most ancient gamers probably don't remember Mego's "Time Out" line, which took the internal of Nintendo's early Game & Watch titles and rebranded them for an American audience that hadn't yet heard of the Japanese game maker.

Now, the Video Game History Foundation (VGHF) has helped preserve the original film of an early Mego Time Out commercial , marking the recovered, digitized video as "what we believe is the first commercial for a Nintendo product in the United States." The 30-second TV spot—which is now available in a high-quality digital transfer for the first time—provides a fascinating glimpse into how marketers positioned some of Nintendo's earliest games to a public that still needed to be sold on the very idea of portable gaming.

Imagine an “electronic sport”

Founded in the 1950s, Mego made a name for itself in the 1970s with licensed movie action figures and early robotic toys like the 2-XL (a childhood favorite of your humble author). In 1980, though, Mego branched out to partner with a brand-new, pre- Donkey Kong Nintendo of America to release rebranded versions of four early Game & Watch titles: Ball (which became Mego's "Toss-Up"), Vermin ("Exterminator"), Fire ("Fireman Fireman"), and Flagman ("Flag Man").

Ludwig van Beethoven is one of the greatest composers of all time, but he was plagued throughout his life by myriad health problems, most notably going mostly deaf by 1818. These issues certainly affected his career and emotional state, so much so that Beethoven requested— via a letter addressed to his brothers—that his favorite physician examine his body after his death to determine the cause of all his suffering.

Nearly two centuries after the composer's demise, scientists say they have sequenced his genome based on preserved locks of hair. While the analysis of that genome failed to pinpoint a definitive cause of Beethoven's hearing loss or chronic digestive problems, he did have numerous risk factors for liver disease and was infected with hepatitis B, according to a new paper published in the journal Current Biology. The researchers also found genetic evidence that somewhere in the Beethoven paternal line, an ancestor had an extramarital affair.

“We cannot say definitely what killed Beethoven, but we can now at least confirm the presence of significant heritable risk and an infection with hepatitis B virus,” said co-author Johannes Krause , an expert in ancient DNA at the Max Planck Institute of Evolutionary Anthropology. “We can also eliminate several other less plausible genetic causes.” The fully sequenced genome will be made publicly available so other researchers can have access to conduct future studies.

Could Leonardo da Vinci's mother, Caterina, have been a slave kidnapped from the mountainous Caucasus region of Central Asia? That's the latest hypothesis re-igniting a long-running debate about the identity of this mysterious woman largely lost to history. Historian Carlo Vecce of the University of Naples told reporters at a Tuesday press conference that he discovered a previously unknown document supporting the claim. He's also written a historical novel about Caterina's life ( Il Sorriso di Caterina or Caterina's Smile ) based on his research.

It's well-established that Leonardo was born in 1452, the illegitimate son of a Florentine notary named Ser Piero d’Antonio and a woman named Caterina. Ser Piero went on to marry a woman named Albiera Amadori, followed by three subsequent marriages after her 1464 death. His various unions produced 16 children (11 of whom survived their early years), in addition to Leonardo, who grew up in his father’s household and received a solid education.

As for Caterina, many historians have identified her as a local peasant girl and eventual wife of a kiln worker named Antonio di Piero del Vacca (nicknamed "L'Accattabriga" or "the quarrelsome one"). But that's all we know of her. So naturally, over the years, various alternative identifications have been suggested. Perhaps the most controversial, proposed in 2014 by Italian historian Angelo Paratico, is that Caterina had been a Chinese domestic slave imported from Crimea by Venetian traders and sold to a Florentine banker.

In a world where millions of people carry a 1990s-grade supercomputer in their pockets , it's fun to revisit tech from a time when a 1 megahertz machine on a desktop represented a significant leap forward. Recently, a collector named Brian Green showed off his vintage computer collection on Twitter, and we thought it would be fun to ask him about why and how he set up his at-home computer lab.

By day, Green works as a senior systems engineer based in Arkansas. But in his off hours, "Ice Breaker" (as he's often known online) focuses his passion on a vintage computer collection that he has been building for decades—and a bulletin board system ( BBS ) called "Particles" he has been running since 1992.

Green's interest in computers dates back to 1980, when he first used an Apple II+ at elementary school. "My older sister brought home a printout from a BASIC program she was working on, and I was fascinated that you could tell a computer what to do using something that resembled English," recalls Green. "Once I realized you could code games, I was hooked."

Polish astronomer Nicolaus Copernicus revolutionized science when he challenged the 1,400-year dominance of Ptolemaic cosmology with the publication of De Revolutionibus Orbium Coelestium ( On the Revolutions of the Heavenly Spheres ) in 1543. His manuscript suggested that the Sun, not the Earth, was at the center of the Solar System, thereby altering our entire view of the Universe and our place in it. Now, a rare, pristine first edition is up for sale for $2.5 million.

The high price tag is a testament not just to the historical importance of the work, but also to the clear provenance and excellent condition of this particular edition, according to Christian Westergaard of Sophia Rare Books, who is handling the sale. (He will be exhibiting the edition at the upcoming New York International Antiquarian Book Fair next month.) A similar copy with just a couple of repairs and a contemporary binding sold at auction for $2.2 million in 2008. But most first editions of De Revolutionibus that come up for sale have dubious provenance, fake bindings, facsimile pages, stamps removed, or similar alterations that decrease the value.

Noted Copernican scholar Owen Gingerich spent 35 years tracking down and examining every surviving copy of the first two editions of De Revolutionibus, ultimately locating 276 first-edition copies (of about 500 originally printed) around the world, most of them part of institutional collections. There are only a handful of editions from Gingerich's census (maybe 10 to 15) in the hands of private collectors, including this one. "It's the holy grail for me," Westergaard told Ars. "If you're going to handle a book in this price range, you want good provenance. You don't want it to suddenly be reported stolen from some library. You want it to be in Gingerich's census. In my opinion, this copy has it all."

Odds are good you read at least one of the umpteen media stories last month about a possible 2,000-year-old "dildo" unearthed near the remains of a Roman auxiliary fort in the UK called Vindolanda. Well, it's either a dildo; a pestle used for grinding cooking, cosmetic, or medicinal ingredients; or something meant to be inserted into a statue and rubbed for good fortune (a common Roman practice). That's what the authors of a February paper in Antiquity concluded, anyway. But now we have another possible explanation to consider: The phallus-shaped artifact might be a drop spindle used for spinning yarn.

As we've reported previously , the Vindolanda site is located south of the defense fortification known as Hadrian's Wall . An antiquarian named William Camden recorded the existence of the ruins in a 1586 treatise. Over the next 200 years, many people visited the site, discovering a military bathhouse in 1702 and an altar in 1715. The Rev. Anthony Hedley began excavating the site in 1814, but he died before he could record what he found for posterity. Another altar found in 1914 confirmed that the fort had been called Vindolanda.

Serious archaeological excavation at the site began in the 1930s under the leadership of Eric Birley , whose sons and grandson continued the work after his death, right up to the present day. The oxygen-deprived conditions of the deposits (some of which extend 6 meters, or 19 feet, into the earth) mean that the recovered artifacts are remarkably well-preserved. These include wooden writing tablets and over 100 boxwood combs, which would have disintegrated long ago in more oxygen-rich conditions.

When Napoleon was infamously defeated at Waterloo in 1815, the conflict left a battlefield littered with thousands of corpses and the inevitable detritus of war. But what happened to all those dead bodies? Only one full skeleton has been found at the site, much to the bewilderment of archaeologists. Contemporary accounts tell of French bodies being burned by local peasants, with other bodies being dumped into mass graves. And some accounts describe how scattered bones were collected and ground up into meal to use as fertilizer.

It's that last claim that particularly interests Tony Pollard, director of the Center for Battlefield Archaeology at the University of Glasgow. He has examined historical source materials like memoirs and journals of early visitors, as well as artworks, to map the missing grave sites on the Waterloo battlefield in hopes of finding a definitive answer. He recently provided an update on his efforts thus far in a recent paper published in the Journal of Conflict Archaeology.

Napoleon had initially been defeated and deposed as emperor of France in 1813, ending up in exile on the island of Elba in the Mediterranean. He briefly returned to power in March 1815 for what is now known as the Hundred Days . Several states opposed to his rule formed the Seventh Coalition, including a British-led multinational army led by the Duke of Wellington, and a larger Prussian army under the command of Field Marshal von Blücher. Those were the armies that clashed with Napoleon's Armée du Nord at Waterloo.
