A B-24 D-1 bomber plane transporting 11 American servicemen was shot down over the South Pacific on March 11, 1944. For more than 70 years, the final resting place of the aircraft nicknamed Heaven Can Wait and the men it carried remained a mystery. Now, through the efforts of Project Recover, it's finally been identified.

Project Recover is an organization dedicated to locating the remains of U.S. aircraft that crashed into the ocean during World War II. To find the wreckage of this particular plane, a team of marine scientists, archaeologists, and historians worked together to trace its final flight.

Heaven Can Wait was on its way to bomb Japanese anti-aircraft batteries around Hansa Bay off the north coast of Papua New Guinea when it went down. Before heading off to Papua New Guinea to survey the area, Project Recover compiled data on the crash from military reports, diary entries from airmen on associated planes, and extended family members.

With that information in hand, the team traveled to the suspected crash site and searched a 10-square-mile patch of sea floor with sonar, divers, and aerial and aquatic robots. It took them 11 days to locate the wreckage of Heaven Can Wait in Hansa Bay, 213 feet beneath the ocean's surface.

Now that the bomber has been found, the U.S. government will assess the site before potentially recovering the remains of the lost servicemen. “This is an important step toward our ultimate goal of identifying and returning home the crew of Heaven Can Wait who bravely served our country during the battle at Hansa Bay,” Dan Friedkin, Project Recover team member and chairman and CEO of the Friedkin Group, said in a statement. “Our search efforts for the more than 72,000 missing American service members from World War II will continue as we seek to bring closure to the families impacted by their loss.”

Scientists Find Fossil of 150-Million-Year-Old Flesh-Eating Fish—Plus a Few of Its Prey

A fossil of an unusual piranha-like fish from the Late Jurassic period has been unearthed by scientists in southern Germany, Australian news outlet the ABC reports. Even more remarkable than the fossil’s age—150 million years old—is the fact that the limestone deposit also contains some of the fish’s victims.

Fish with chunks missing from their fins were found near the predator fish, which has been named Piranhamesodon pinnatomus. Aside from the predator’s razor-sharp teeth, though, it doesn’t look like your usual flesh-eating fish. It belonged to an extinct order of bony fish that lived at the time of the dinosaurs, and until now, scientists didn’t realize there was a species of bony fish that tore into its prey in such a way. This makes it the first flesh-eating bony fish on record, long predating the piranha. 

“Fish as we know them, bony fishes, just did not bite flesh of other fishes at that time,” Dr. Martina Kölbl-Ebert, the paleontologist who found the fish with her husband, Martin Ebert, said in a statement. “Sharks have been able to bite out chunks of flesh, but throughout history bony fishes have either fed on invertebrates or largely swallowed their prey whole. Biting chunks of flesh or fins was something that came much later."

Kölbl-Ebert, the director of the Jura Museum in Eichstätt, Germany, says she was stunned to see the bony fish’s sharp teeth, comparing it to “finding a sheep with a snarl like a wolf.” This cunning disguise made the fish a fearful predator, and scientists believe the fish may have “exploited aggressive mimicry” to ambush unsuspecting fish.

The fossil was discovered in 2016 in southern Germany, but the find has only recently been described in the journal Current Biology. It was found at a quarry where other fossils, like those of the Archaeopteryx dinosaur, have been unearthed in the past.

Advanced CT Scans Reveal Blood Vessels and Skin Layers in a Mummy's Hand

Mummies hold some intriguing secrets to their pasts, like the food they ate and the diseases they had when they were alive. Now scientists are using a tool originally designed for medicine to get an even deeper look at the clues mummified bodies carry with them into the present day, Gizmodo reports.

In a proof-of-concept study published in the journal Radiology, researchers from the KTH Royal Institute of Technology in Sweden detail how a new-and-improved CT scanning technique can be used to visualize the interior of mummies on a microscopic level. By creating detailed X-ray images, CT scans allow doctors to see inside their patients without invasive surgery. Archaeologists have been using this technology to study delicate ancient artifacts for years, but the level of detail that can be achieved this way—especially when it comes to looking at interior soft tissue—is limited.

The upgraded version of the tech, called phase-contrast CT scanning, measures the phase shift, or the change in the position of a light wave, that occurs when X-rays pass through solid objects. The images generated this way have a higher contrast level than conventional X-rays, which means they capture more detail.

Doctors have been using this 10-year-old technology to examine soft tissues like organs and veins in living patients, but it hadn't been used on a mummy until recently. Working with a mummified human right hand dating back to 400 BCE in Egypt, which they borrowed from the Museum of Mediterranean and Near Eastern Antiquities in Stockholm, the researchers fired up a phase-contrast CT scanner. It produced images with a resolution of 6 to 9 microns, giving a clear picture of the different layers of skin, individual cells in the connective tissue, and the blood vessels in the nail bed—all without damaging the artifact. Previously, researchers looking to study these same tissues in mummies would have needed to use a scalpel.

As Ars Technica reports, a phase-contrast CT scanner is similar in cost to the conventional machine. The study authors hope their work will lead to phase-contrast CT scanning becoming just as common in archaeology as regular CT scanning, potentially creating new research opportunities in mummies that will be discovered in the future and even in artifacts that have already been examined.
