Recovering the USS Oklahoma was the largest naval salvage operation ever attempted

In 1943, engineers spent three months using 21 giant winches and an intricate cable system to right the capsized USS Oklahoma. It was the largest naval salvage effort ever attempted at the time and remains one of the most complex in history.

An archive of some of America's most significant shipwrecks

From The Portland—known as New England's "Titanic"—to the Civil War's USS Monitor, this archive from the National Oceanic and Atmospheric Administration provides overviews of some of the most well-known shipwrecks in US history.

A new scan of the Titanic reveals details about its final hours

Using over 700,000 images captured by underwater robots, researchers created a highly detailed 3D "digital twin" of the Titanic. The analysis gives us new insights into the life of the ship that lays 3,800m down in the icy waters of the Atlantic. Emerging details from close-up images, such as a smashed porthole likely caused by the iceberg, match the eye-witness accounts of what happened. Read for more insights into the devastating wreck.

A single bomb on the USS Arizona killed 1,177 crew members in seconds

Historians estimate only 1% of shipwrecks have been discovered

The oldest known shipwreck dates to around 2,700–2,300 BCE, but evidence suggests humans started open-ocean sailing at least 50,000 years ago. Many have completely deteriorated but artifacts aboard the vessels remain, while many lack historical records of the event or location.

In 1915, workers recovered a submarine-like vessel from the Chicago River, prompting fears of German espionage

The Foolkiller: The mysterious submarine at the bottom of the Chicago River

Cadaver dogs are helping archaeologists uncover decaying history

Archaeologists are increasingly relying on dogs to help find decaying bodies at burial sites, some of them up to thousands of years old. This is helping archaeologists to detect past remains without ever touching a shovel, which means there's less...

Evidence suggests some of the Challenger's crew may have been alive after the explosion

Recovery of the intact crew cabin and later analysis of flight data led investigators to conclude the astronauts likely survived the initial breakup and remained alive during the roughly two-minute descent before the cabin struck the ocean.

The Golden State killer case spotlights how genetic testing can affect your—and your relatives'—privacy

Police managed to use consumer DNA test results to close a case 32 years after a killer was believed to have committed at least 12 murders and 50 rapes. Their "smoking gun": They compared a DNA sample from the crime scene to genetic data relatives had shared on an open-source genealogy database. The suspect was caught after investigators explored family trees on this database and connected the dots from over 100 distant relatives who had some percentage of DNA that matched the killer. (Some users may encounter a paywall.)

What happens when a whale dies and falls to the ocean floor

A large whale's body can blanket more than 538 square feet of ocean floor. That's an enormous amount of organic matter, providing food for the ecosystem for centuries. Researchers have discovered bones on the seafloor from whale species that have been extinct for over 100,000 years.

Scientific advances have transformed understanding of Stonehenge’s builders

Techniques such as radiocarbon dating, DNA analysis, and isotopic testing have revised scholars' understanding of Stonehenge. This article presents evidence suggesting that societies were more cooperative and less violent than earlier theories had suggested.

Abraham Lincoln's assassination helped create the multibillion-dollar funeral business

After the president was killed in April 1865, he became one of the first well-publicized embalming examples in the US. The burgeoning science enabled his body to go on a multistate tour. Prices soon climbed for the process and fueled more wakes, perhaps helping to lay the foundation for the pricy funeral industry.

At the beginning of the 20th century, a group of young men ate standard American food—replete with food additives like borax and formaldehyde—as part of government research to better understand food safety.

Santa Barbara divers helped innovate deepwater diving technology

Divers in the Santa Barbara channel innovated a more efficient type of diving helmet in the 1960s that used helium to allow for longer, deeper excursions for oil surveying, abalone collecting, and more. These innovators have since set the standard worldwide for military and industrial diving.

The US Navy prohibited sailors from toasting with water

A 1986 manual stated that "Tradition is that the object of a toast with water will die by drowning." The superstition is rooted in ancient Greek mythology, where the dead in the underworld drank from the River Lethe to forget their previous lives. As such, the Greeks believed toasting someone with water to be a way of cursing them to the underworld.

Native American tribes still are waiting for museums to return the remains of their ancestors

The remains of more than 100,000 Native Americans are held by prestigious US institutions, despite a 1990 law meant to return them to tribal nations. Here’s how their ancestors were stolen—and how tribes are working to get them back.

The final shots of the Civil War were fired in the Arctic over 2 months after the South's surrender

In June 1865—two months after Lee's surrender—the Confederate raider CSS Shenandoah unknowingly attacked Union whaling ships in the Arctic. When the crew learned the war was over, they sailed 9,000 miles to surrender in Liverpool, England.

The ghost of Bobby Dunbar

In 1912, a four-year-old Louisiana boy went missing for eight months. Contemporary accounts differed in his mother's reaction upon seeing him; some claimed she was overjoyed, others that she didn't recognize him. Shortly after, a second woman claimed the child was hers, though he remained with the first woman. In 2004, DNA analysis determined the child had not been related to the family, suggesting the kidnapping was never solved.

Sewage on cruise ships is cleaned onboard by bacteria and advanced filtration systems

A cruise ship's onboard sewage plant processes black water, human waste or sewage, and gray water, wastewater from sinks, showers, and washing machines. Treated water is stored until the ship reaches a distance where it can legally discharge it.

The first identification of Alzheimer's was made in 1906

The first case of Alzheimer's disease dates to the early 20th century when Dr. Alois Alzheimer had 51-year-old Auguste Deter as a patient. Deter struggled with sudden memory issues and aggressive, irrational behavior. After Deter's death, Alzheimer examined her brain and found strange collections of molecular pileups.

Oxford scientists turned Fleming’s mold discovery into medicine
