What killed King Tut? And what happened to his body afterward?
British archaeologist Howard Carter first discovered the Egyptian pharaoh’s well-preserved mummy in 1922. Ever since, scientists have tried to figure out what killed the pharaoh, who reigned for 10 years until his death at age 19 around the year 1324 B.C. Theories include everything from epilepsy to blunt force trauma.
But there’s never been a clear consensus.
Now British egyptologist Dr. Chris Naunton, director of the Egypt Exploration Society, has thrown his hat into the already-crowded ring. A new documentary will present his findings, which suggest King Tut died in a chariot accident — and then later spontaneously combusted inside his sarcophagus due to a botched embalming.
Holy smokes!

Give these dancing water droplets a stage.
In a new video, part of upcoming research out of Clemson University, scientists make levitating water drops bob and jive using ultrasonic waves.
While researchers have demonstrated similar spectacles before — the process is called acoustic levitation — the Clemson team took the experiment a step further and influenced the shape of the water drops.
How did they do it?
The team explains in their pre-published research that when a drop of water is positioned within an acoustic field, the pressure exerted on it creates a flattened spherical shape. The water droplet levitates when multiple sound waves with the same frequency interfere with each other and create a standing wave, causing anything within the acoustic field to be suspended. To mold the shape of the water droplet, researchers used an ultrasonic standing wave to manipulate the field by increasing/decreasing the strength and changing the frequency. The end result is pretty mesmerizing.

Were the Vikings even more brutal than we realized?
From the ninth century to the 11th century, marauding Viking warriors laid waste to a broad swath of Europe, and in the process often took slaves for physical labor and sex. Now researchers from the University of Oslo in Norway say they’ve found new evidence suggesting that when their Viking masters died, slaves were beheaded and buried along with them.
Elise Naumann, an archaeologist at the university, and her colleagues reached this conclusion after analyzing the skeletal remains of 10 Viking-era bodies originally discovered decades ago in Flakstad, Norway. The researchers paid particular attention to graves that contained the remains of two or more bodies — but only one head.
“We were curious about the Flakstad double burials,” Naumann told The Huffington Post in an email. “They are poorly documented, and the definition of double burial was doubted at the time. It was thus strange that only one skull was retrieved from each double burial, but postcranial bones from two or three individuals.”

A new video lets viewers experience the sensation of flying over the Martian surface based on actual topographical data taken by a European satellite orbiting the red planet.
The mountains, craters, ancient river beds and lava flows that mark the Martian landscape are visible in images from a stereographic camera aboard ESA’s Mars Express probe.
The German Aerospace Center (DLR) released the video as part of celebrations commemorating ten years since Mars Express launched in June 2003, and the DLR’s Stephan Elgner, a member of the mission’s planetary cartography team, wrote the original soundtrack.
Mars Express has so far orbited the planet nearly 12,500 times, building up an almost planet-wide digital topographical model.

The tomb of a prestigious ancient Egyptian physician who counted pharaohs among his clients is believed to have been found in a vast necropolis southwest of Cairo.
Part of a large plot measuring roughly 70 feet by 46 feet, the tomb of Shepseskaf-Ankh was unearthed this week in Abusir near modern-day Giza, the Agence France-Presse reports. The site is a burial place for many important figures from the Fifth Dynasty, which existed about 4,000 years ago.
“This discovery is important because this is the tomb of one of the greatest doctors from the time of the pyramid builders, one of the doctors closely tied to the king,” Antiquities Minister Ibrahim Ali said in a statement, per AFP.

The age on your driver’s license may not be exactly correct — well, for certain parts of your body anyway.
A new study, published Monday in peer-reviewed journal Genome Biology, suggests that we all have an internal biological clock that tracks the aging process — and may reveal the true age of our cells and tissues. It’s hidden right in our DNA.
“The epigenetic clock really allows someone to objectively measure the age of cells and tissues,” study author Dr. Steve Horvath, a professor of human genetics and biostatistics at the University of California, Los Angeles, told The Huffington Post. “Therefore, it can be used to study aging.”
This internal “timepiece” may also be used to compare the various ages of elements in the body. For instance, in his research, Horvath found that female breast tissue ages several years faster than the rest of the body, which may explain why breast cancer is the most common cancer in women. Cancer also greatly accelerates the age of affected tissues.

The earliest, now-extinct human lineages, once thought to be multiple species, may actually have been one species, researchers now controversially suggest.
Modern humans, Homo sapiens, are the only living member of the human lineage, Homo, which is thought to have arisen in Africa about 2 million years ago at the beginning of the ice age, also referred to as the Pleistocene Epoch. Many extinct human species were thought to once roam the Earth, such as Homo habilis, suspected to be among the first stone-tool makers; the relatively larger-brained Homo rudolfensis; the relatively slender Homo ergaster; and Homo erectus, the first to regularly keep tools it made.
To learn more about the roots of the human family tree, scientists investigated a completely intact, approximately 1.8-million-year-old skull excavated from the medieval hilltop town of Dmanisi in the Republic of Georgia. Archaeological excavations there about 30 years ago unexpectedly revealed that Dmanisi is one of the oldest-known sites for ancient human species out of Africa and the most complete collection of Homo erectus skulls and jaws found so far. The world’s largest, extinct cheetah species once lived in the area, and scientists cannot rule out whether it fed on these early humans.

Ah, the weekend. Many of us who work long hours during the week may see the weekend as an opportunity to “catch up” on some rest by sleeping in. But is it really possible to recover from sleep loss by finding time later to snooze, and does it do the mind and body any good?
For starters, a study published in the current issue of the American Journal of Physiology-Endocrinology and Metabolism suggests that using your weekend to sleep in actually doesn’t fix all the damage caused by missing out on some slumber during the week.
“The major take away message is that extended sleep helps, but only to some extent,” study co-author Dr. Alexandros Vgontzas, professor at Penn State University’s Hershey Sleep Research & Treatment Center, told The Huffington Post in an email. “The repeated cycle of restriction/recovery may be harmful to your health in the long run.

Researchers studying clay balls from Mesopotamia have discovered clues to a lost code that was used for record-keeping about 200 years before writing was invented.
The clay balls may represent the world’s “very first data storage system,” at least the first that scientists know of, said Christopher Woods, a professor at the University of Chicago’s Oriental Institute, in a lecture at Toronto’s Royal Ontario Museum, where he presented initial findings.
The balls, often called “envelopes” by researchers, were sealed and contain tokens in a variety of geometric shapes — the balls varying from golf ball-size to baseball-size. Only about 150 intact examples survive worldwide today.
The researchers used high-resolution CT scans and 3D modeling to look inside more than 20 examples that were excavated at the site of Choga Mish, in western Iran, in the late 1960s. They were created about 5,500 years ago at a time when early cities were flourishing in Mesopotamia.

While Albert Einstein, considered one of the foremost geniuses of the 20th century, has transformed scientists’ understanding of physics and astronomy with his theories, the intellect of Einstein himself has remained misunderstood.
Ever since pathologist Dr. Thomas Harvey harvested the scientist’s brain in 1955, researchers have tried to crack the mystery of Einstein’s genius by observing that brain.
Now scientists think they’ve found a clue. A new study, published in the journal Brain on September 24, 2013, suggests that the two hemispheres in Einstein’s brain were unusually well connected.
“This study, more than any other to date, really gets at the ‘inside’ of Einstein’s brain,” study co-author Dean Falk, an evolutionary anthropologist at Florida State University, said in a written statement. “It provides new information that helps make sense of what is known about the surface of Einstein’s brain.”
In the study, Falk and her colleagues looked at a series of unpublished photographs of the brain, taken from many angles. The team analyzed the thickness of the brain’s corpus callosum — the large bundle of fibers that connects the brain’s two cerebral hemispheres and allows them to communicate with each other. Then the researchers compared that part of Einstein’s brain to the same structure in 15 elderly males and 52 younger men from 1905.
