An extraordinary ancient Syrian settlement shines a light on one of the most important moments in human history.

Joan Oates’s sharp blue eyes spotted something that was not right. Standing on the windy summit of a vast, human-made mound in northeastern Syria, the wiry 81-year-old archaeologist noticed an ugly scar that had been left by a backhoe on one of the smaller mounds ringing the ancient city of Nagar, where she has excavated for a quarter century. Oates had just arrived to begin her latest season at the site, and this blemish on her cherished landscape annoyed her. Two young men on her team volunteered to investigate the damage. They returned, shaken. Jumping into the trench, one of them had come face-to-face with a skull. “Everywhere we looked, there were human bones,” one recalls. “There were an enormous number of dead people.”

From Technology Review:

Autoantibodies could alert doctors to cancer development.

A new screening tool developed by scientists in Denmark may help detect the earliest stages of cancer by taking advantage of the body's own defenses. The researchers constructed a microarray system that analyzes patients' blood for a specific class of immune agents called autoantibodies. These are agents that attack the body's own tissue, targeting what they perceive as "foreign" cells, such as specific molecules on the surface of tumors.

From Popular Mechanics:

Can the much-maligned tilt-rotor aircraft earn respect on the job?

USS Bataan—After a couple of days working just under the flight deck of the amphibious assault ship USS Bataan you begin to recognize the signature sounds of various helicopters: The high-pitch rip of an HH-60 Knighthawk, the deep, rapid drum beat of the giant CH-53D Super Stallion or the rhythmic song of a UH-1 Huey. So the crew of the USS Bataan, outside Haiti, knows when something new lands onboard. Seconds after a bass-drum vibration shook the ward-room lounge, an excited Marine officer stuck his head in and announced "The Ospreys are taking off! Let's go up to the top of the island and watch!"

Genetic Disorder Turns Risk-Averse Into Gamblers

The study found that people with a damaged amygdala had a higher inclination to risk losing money as a result of reckless gambling. Alamy

From The Independent:

The brains of people who risk everything when gambling may be wired up differently to those of the naturally cautious, according to a study that appears to have discovered a neurological basis for reckless behaviour.

The research found that people were far more gullible to high-risk gambling when a small but distinct part of their brain had been damaged as a result of a rare genetic disorder. They showed little of the natural aversion to losing something of value that most people are born with.

From The Guardian:

It will soon be half a century since the American astronomer Frank Drake first pointed a radio telescope at the star Tau Ceti in the hope of picking up an extraterrestrial broadcast, and we still haven't heard anything. So is there anyone out there?

Fifty years ago Frank Drake – then a young astronomer from Cornell University – began an experiment that would have profound implications for humanity's understanding of its place in the cosmos. He turned the newly constructed Green Bank radio telescope in West Virginia towards Tau Ceti, a nearby star that is similar to our own Sun.

Smoking May Pose 'Third-Hand' Cancer Hazard

From New Scientist:

Residues of cigarette smoke deposited on indoor surfaces can turn carcinogenic when they react with airborne chemicals. This "third-hand" exposure could in theory cause health problems, particularly in children, says Hugo Destaillats, a specialist in indoor pollution at Lawrence Berkeley National Laboratory in California.

His team found several chemicals on the inside of the cab of a half-pack-a-day smoker's truck, including a carcinogen called a NNK. Destaillats's team reckon that NNK is produced when nicotine from tobacco smoke reacts with nitrous acid in the air.
