A new report in the Wall Street Journal states that Trump administrati stanley website on officials are working on creating a travel corridor between New York City and London  as soon as the holidays.  The arrangement would require travelers to be tested for covid-19, the disease caused by the novel coronavirus, before their flight and then again upon arrival. It would also include shorter quarantine periods when travelers arrive at their destinations. According to the Journal, Trump administration officials decided to focus on implementing travel corridors between the U.S. and international destinations because of the growing availability of covid-19 tests in the U.S.     U.S. officials expect to rely on rapid tests as the primary tool to maintain covid-free travel corridors, the Journal reported. Although the type of test was not specified, its probable that the tests involved would be聽antigen tests, which are carried out with a nasal or throat swab and provide results in one hour or less. According to the Food and Drug Administration, positive covid-19 results from antigen tests are usually highly accurate, but nega stanley water bottle tive results may need to be confirmed with a molecular test. Molecular te stanley water bottle sts are typically highly accurate and usually do not need to be repeated, the FDA states, but getting results can take anywhere from a day to a week.

 Within four million years of the Cretaceous-Paleogene mass extinction event  K-Pg 鈥攁 mere blink of the eye in evolutionary terms鈥攁s many as ten major bird lineages were already in place, according to new research published yesterday in Proceedings of the National Academy of Science. With the dinosaurs gone, and with habitats re-emerging, many of these pioneering species would diversify even further, eventually evolving into the 10,000 species聽of birds around today.     https://gizmodo/this-new-dinosaur-looked-an-awful-lot-like-a-chicken-1794833786 Birds evolved from dinosaurs, but dinosaurs didnt just su stanley website ddenly become birds during the K-Pg extinction event. The relatives of modern birds first emerged around 1 stanley cup 25 million years ago, during the Early Cretaceous. Thats about 60 million years before that dreaded asteroid struck the Yucatan Peninsula, wiping out an estimated 75 percent of all species on Earth鈥攁nd virtually every creature larger than 55 pounds. The K-Pg event may not have created birds, but it did produce a filter through which only a select group of bird species were able to squeeze through. A similar process happened to mammals, and as a recent study pointed out, amphibian stanley usa s. As the old saying goes, the meek shall inherit the Earth, and this is what scientists assumed happened for birds at the K-Pg boundary. Unfortunately, these feathered creatures, with their brittle and easily breakable bones, dont fossilize well, and theres a frustrating fossil gap around this tim
