Leonardo da Vinci robot wows Tokyo crowd

The International Robot Exhibition 2015 (iREX) opened its doors to the public on Wednesday (December 2) at the Tokyo Big Sight center for five days of displays and seminars on the latest robot technology. Attracting much attention were disaster response robots created by Japan's NEDO (New Energy and Industrial Technology Development Organization). "Most of our jobs, of course, are for human beings, and so we think humanoids can handle these kinds of things," explained Satoshi Kochiyama, Project Manager in the Machine Systems Department.

Lightest Metal Ever Is 99.9 Percent Air

How do you build the world’s lightest metal? The material, known as a "microlattice," was developed by scientists at HRL Laboratories in Malibu, California, which is co-owned by Boeing and General Motors. The new microlattice is made up of a network of tiny hollow tubes and is roughly 100 times lighter than Styrofoam.

Biblical King's Royal Seal Unearthed Near Temple Mount

The royal seal of an ancient biblical king has been unearthed near the Temple Mount in Jerusalem. The seal, a clay impression depicting a two-winged sun with two ankh symbols on either side, was once used to seal papyrus documents associated with King Hezekiah, who ruled the kingdom of Judea from 727 B.C. to 698 B.C. The seal was unearthed in a trash heap near the walls of the ancient Temple Mount. "Although seal impressions bearing King Hezekiah's name have already been known from the antiquities market since the middle of the 1990s — some with a winged scarab (dung beetle) symbol and others with a winged sun — this is the first time that a seal impression of an Israelite or Judean king has ever come to light in a scientific archaeological excavation," Eilat Mazar, an archaeologist at the Hebrew University of Jerusalem who led the excavations, said in a statement.

New Type of Carbon Is Harder and Brighter Than Diamonds

"This new phase is very unique," said study co-author Jagdish Narayan, a materials scientist at North Carolina State University. In this subterranean pressure cooker, carbon dioxide molecules were crushed with pressures of about 725,000 lbs. per square inch (5 million kilopascals) and heated to a sweltering 2,200 degrees Fahrenheit (1,200 degrees Celsius), according to a 2012 study in the journal Nature.

'Spooky Action at a Distance' Author George Musser Talks Physics Loopholes

All of the phenomena are examples of nonlocality, which Albert Einstein famously described as "spooky action at a distance." (The book's subtitle refers to the phenomenon's significance to black holes, the Big Bang and theories of everything.) There are hints of nonlocality in multiple fields of physics, and Musser chronicles the messy struggle to understand how it fits into the theories and assumptions that make up physicists' understanding of the universe. Space.com talked with Musser about his new book and the concept of nonlocality, which he called unsettling, in the sense of something that drives research forward — unsettling but also intriguing.

Hawaii court revokes permit for telescope project on volcano

(Story corrects Thursday to Wednesday in paragraph 5) By Suzannah Gonzales (Reuters) - The Hawaii Supreme Court on Wednesday revoked a permit that would have allowed the controversial construction of one of the world's largest telescopes on a dormant volcano considered an ideal location on Earth to view the stars. Issuing the permit to construct a 180-foot high, $1.4 billion astronomical observatory on the Mauna Kea volcano on Hawaii's Big Island did not comply with case law, statutes or the state constitution, court documents showed. In November, the court temporarily blocked construction of the telescope, a collaboration between China, India, Canada, Japan and the United States, after a challenge by Native Hawaiians and environmentalists who said the project would damage sacred lands.
