E.T. Phones Earth? 1,500 Years Until Contact, Experts Estimate

"Communicating with anybody is an incredibly slow, long-duration endeavor," said Evan Solomonides at a press conference June 14 at the American Astronomical Society's summer meeting in San Diego, California. Solomonides is an undergraduate student at Cornell University in New York, where he worked with Cornell radio astronomer Yervant Terzian to explore the mystery of the Fermi paradox: If life is abundant in the universe, the argument goes, it should have contacted Earth, yet there's no definitive sign of such an interaction. It takes a long time to reach anyone, even at the speed of light," he said.

Augmented-Reality Diving Helmets Join the US Navy

New high-tech diving helmets being developed by the U.S. Navy will incorporate augmented-reality tech to keep naval divers safe on underwater missions. The U.S. Navy announced this month a "next-generation" and "futuristic" system: the Divers Augmented Vision Display (DAVD). "By building this HUD directly inside the dive helmet instead of attaching a display on the outside, it can provide a capability similar to something from an 'Ironman' movie," Dennis Gallagher, underwater systems development project engineer at the Naval Surface Warfare Center Panama City Division, said in a statement.

Lost 5,000-Year-Old Neolithic Figurine Rediscovered in Scotland

A 5,000-year-old whalebone figurine, one of the oldest representations of a human form found in Britain, has been rediscovered after going missing for more than 150 years. The figurine was first discovered in the 1850s at the Skara Brae archaeological site in the Orkney Islands, at the northern tip of Scotland, and was part of the private collection of the local "laird," or landowner, in the 1860s. But it was thought lost until British archaeologist David Clark rediscovered it in a box in the archives of the Stromness Museum at Orkney in April.

Human flights to Mars still at least 15 years off: ESA head

You'll have to wait at least 15 years for the technology to be developed, the head of the European Space Agency (ESA) said, putting doubt on claims that the journey could happen sooner. "If there was enough money then we could possibly do it earlier but there is not as much now as the Apollo program had," ESA Director-General Jan Woerner said, referring to the U.S. project which landed the first people on the moon. Woerner says a permanent human settlement on the moon, where 3D printers could be used to turn moon rock into essential items needed for the two-year trip to Mars, would be a major step toward the red planet.

Male Doctors, Female Nurses: Subconscious Stereotypes Hard to Budge

The conscious mind is quick to adapt to information that flies in the face of stereotype, but the subconscious may ignore even the most glaring of facts, new research finds. When people are given two names, Jonathan and Elizabeth, and asked who is a doctor and who is a nurse, the respondents typically say that each is equally likely to be in either profession. This kind of implicit association, or subconscious pairing based on stereotype, is well-known in psychology.

Rays Don't Stray: Giant Mantas Stick Close to Home

Until recently, manta rays — which sail through tropical and temperate ocean waters, looking much like enormous kites — were thought to migrate great distances across ocean basins, as do many of the largest marine animals. Researchers investigated data gathered from tracking devices on the manta rays, as well as chemical and DNA analysis of the rays' muscle tissues. The discovery radically changes scientists' understanding of mantas' habits and carries dramatic implications for their conservation.

India launches 20 satellites at one go; most to serve U.S. customers

India successfully launched 20 satellites in a single mission on Wednesday, with most of them set to serve international customers as the South Asian country pursues a bigger share of the $300 billion global space industry. It was the most satellites India has put in space at one go, though Russia set the record of 37 for a single launch in 2014. Prime Minister Narendra Modi described the launch as "a monumental accomplishment" for the state-run Indian Space Research Organisation (ISRO).
