Thanks to a new calibration of the versatile argon-argon dating technique, geochronologists have established a more precise date for the dinosaur die-off at the end of the Cretaceous period: 65.95 million years ago, give or take 40,000 years.This improves on the previous date of 65.5 million years plus or minus 300,000 years, but more importantly, brings argon-argon dating into agreement with other dating methods.Transferring these so-called “qubits” allows information to be relayed securely and instantaneously.When a particle is entangled with another, everything that happens to one affects the other.All articles contain citations and abstracts and many are available in full text.Included journals often represent some of the core scholarly publications in that particular field and many are peer reviewed. Academic Universe This is the Lexis-Nexis database in a version tailored specifically for colleges and universities.The experiment saw Chinese scientists send a photon up away from Earth, further than ever before.Teleportation of this kind uses the bizarre effects of quantum entanglement, rather than physically hurling the object itself over distances.

The experiment is part of an ongoing effort by researchers using the Micius satellite to achieve long-distance quantum communication, a feat that would yield hacker-proof information networks.
In this most recent work, researchers from the University of Science and Technology of China beamed photons to the satellite and transmitted the state of other photons on the ground using entanglement.
The database also includes some full text monographs, reports and conference proceedings. It contains mostly full-text information in the areas of federal and state law, legal news and law reviews, finance, politics, government, taxation, medicine, health, company information, business, market news and general news .
Among the over 5000 publications included are magazines, journals, newspapers, wire services, federal & state statutes, federal & state court opinions, directories and SEC filings.
