New U.S. airport security measures mark the end of broad national and racial profiling in favor of intelligence-based screening criteria.
New U.S. airport security measures mark the end of broad national and racial profiling in favor of intelligence-based screening criteria. "Travellers will be picked out according to how closely they match intelligence on potential terrorist threats. A senior administration official, who spoke to reporters on condition of anonymity, said the new system would require travellers who match information about terrorism suspects, such as a physical description, partial name or travel pattern, to undergo additional screening. 'So it's much more tailored to what the intel is telling us, what the threat is telling us, as opposed to stopping all individuals of a particular nationality or all individuals using a particular passport,' the official said. He described the measures being scrapped as a 'blunt-force instrument'. The names of terrorism suspects identified by the US government will continue to be included on security watch lists and no-fly lists as a part of airline security. The new policy affects US citizens, as well as travellers coming into the United States from abroad. The measures in force since January required that passengers travelling to the US from 14 countries be subjected to especially rigorous pre-flight screening."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
