Cheaper, quicker, and easier. One COVID-19 testing rolling out in the fall looks to achieve all three and maybe even one day mail the tests straight to your home.“Involves just a nasal swab so not a nasopharyngeal swab, just around the rim of the inside of the nose rather than tickling the brain,” said Dr. Joseph Petrosino.The test costs and lets you know if you’ve got the coronavirus within 15 minutes.So far it’s reporting an accuracy rate in clinical labs of 97%.Dr. Petrosino, a molecular virologist with Baylor College of Medicine, took an independent look at the Binax Now ABBOT Rapid test rolling out in October.He says they’re reliable, easy to use, and less vulnerable to supply chain interruptions.“The test is just made out of cardboard and paper, it doesn’t rely on a lot of supply chain plastics or other needs that could potentially hold things up,” said Dr. Petrosino.However, antigen tests like these have been found to produce more false negatives than lab-based tests.Dr. Petrosino says the key is the affordability that would allow large numbers of people at schools and businesses to get tested more frequently, isolating potential outbreaks.“What’ll happen is you’ll have a band that appears if you’re positive as well as a band that relates to whether or not the test worked itself,” said Dr. Petrosino.There’s also a free app that works in conjunction with the test.It allows people to display their results in places where negative tests may eventually be needed for entry, such as schools, workplaces, or large events.Last week, President Donald Trump said the federal government will buy 150 million of the tests to distribute across the country.Fifty million are expected to be available to purchase in October, but folks interested will need to get them at a medical clinic, at least for now.“Currently, you can’t get this test directly, but in the future, you may be able to,” said Dr. Petrosino.This story was first published by Cameron Polom at KNXV in Phoenix, Arizona. 2015

CAPE CANAVERAL, Fla. (AP) — The spacecraft team that brought us close-ups of Pluto will ring in the new year by exploring an even more distant and mysterious world.NASA's New Horizons spacecraft will zip past the scrawny, icy object nicknamed Ultima Thule (TOO-lee) soon after the stroke of midnight.One billion miles beyond Pluto and an astounding 4 billion miles from Earth (1.6 billion kilometers and 6.4 billion kilometers), Ultima Thule will be the farthest world ever explored by humankind. That's what makes this deep-freeze target so enticing; it's a preserved relic dating all the way back to our solar system's origin 4.5 billion years ago. No spacecraft has visited anything so primitive."What could be more exciting than that?" said project scientist Hal Weaver of Johns Hopkins University, part of the New Horizons team.Lead scientist Alan Stern of Southwest Research Institute in Boulder, Colorado, expects the New Year's encounter to be riskier and more difficult than the rendezvous with Pluto: The spacecraft is older, the target is smaller, the flyby is closer and the distance from us is greater.NEW HORIZONSNASA launched the spacecraft in 2006; it's about the size of a baby grand piano. It flew past Pluto in 2015, providing the first close-up views of the dwarf planet. With the wildly successful flyby behind them, mission planners won an extension from NASA and set their sights on a destination deep inside the Kuiper Belt. As distant as it is, Pluto is barely in the Kuiper Belt, the so-called Twilight Zone stretching beyond Neptune. Ultima Thule is in the Twilight Zone's heart.ULTIMA THULEThis Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote. In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world. When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.ARE WE THERE YET?New Horizons will make its closest approach in the wee hours of Jan. 1 — 12:33 a.m. EST. The spacecraft will zoom within 2,200 miles (3,500 kilometers) of Ultima Thule, its seven science instruments going full blast. The coast should be clear: Scientists have yet to find any rings or moons around it that could batter the spacecraft. New Horizons hurtles through space at 31,500 mph (50,700 kph), and even something as minuscule as a grain of rice could demolish it. "There's some danger and some suspense," Stern said at a fall meeting of astronomers. It will take about 10 hours to get confirmation that the spacecraft completed — and survived — the encounter.POSSIBLY TWINSScientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, it's likely 20 miles (32 kilometers) long at most. Envision a baked potato. "Cucumber, whatever. Pick your favorite vegetable," said astronomer Carey Lisse of Johns Hopkins. It could even be two bodies connected by a neck. If twins, each could be 9 miles to 12 miles (15 kilometers to 20 kilometers) in diameter.MAPPING MISSONScientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth. As for color, Ultima Thule should be darker than coal, burned by eons of cosmic rays, with a reddish hue. Nothing is certain, though, including its orbit, so big that it takes almost 300 of our Earth years to circle the sun. Scientists say they know just enough about the orbit to intercept it.COMPARING FLYBYSNew Horizons will get considerably closer to Ultima Thule than it did to Pluto: 2,220 miles versus 7,770 miles (3,500 kilometers vs. 12,500 kilometers). At the same time, Ultima Thule is 100 times smaller than Pluto and therefore harder to track, making everything more challenging. It took 4 ? hours, each way, for flight controllers at Johns Hopkins' Applied Physics Lab in Laurel, Maryland, to get a message to or from New Horizons at Pluto. Compare that with more than six hours at Ultima Thule.WHAT'S NEXTIt will take almost two years for New Horizons to beam back all its data on Ultima Thule. A flyby of an even more distant world could be in the offing in the 2020s, if NASA approves another mission extension and the spacecraft remains healthy. At the very least, the nuclear-powered New Horizons will continue to observe objects from afar, as it pushes deeper into the Kuiper Belt. There are countless objects out there, waiting to be explored. 4591

CAPE CANAVERAL, Fla. (AP) — The first astronauts launched by SpaceX are breaking new ground for style with hip spacesuits, gull-wing Teslas and a sleek, matching rocketship. The color coordinating — white with black trim — is thanks to Elon Musk, the driving force behind both SpaceX and Tesla. NASA astronauts Doug Hurley and Bob Behnken like the new look. The true test comes Wednesday when Hurley and Behnken climb aboard a SpaceX Dragon capsule atop a SpaceX Falcon 9 rocket and, equipment and weather permitting, shoot into space. It will be the first astronaut launch from Florida’s Kennedy Space Center since the last shuttle flight in 2011.The launch also marks the first attempt by a private company to send astronauts into orbit. Only the governments of the U.S., Russia, and China have done that. 815

Carl Kasell, a fixture on NPR for more than 30 years on "Morning Edition" and later its quiz show "Wait Wait ... Don't Tell Me!," died Tuesday from complications from Alzheimer's disease. He was 84.Kasell began his career at NPR as a part-time employee on "All Things Considered" in the mid-1970s, then became the news announcer for the first broadcast of "Morning Edition" in 1979.In that role Kasell became one of public radio's most recognizable voices. Yet after years of being associated with breaking news, he had the opportunity to showcase a lighter side of himself starting in 1998 as judge and scorekeeper on "Wait Wait," hosted by Peter Sagal. An early prize for winners was to have Kasell record the outgoing message on their answering machine.In a statement, Sagal called him "the kindest, most decent person I have ever known," adding that after listening to him for years, "Hearing him say my name, that very first time, made me feel like I had somehow made it." Kasell became "scorekeeper emeritus" in 2014.Kasell's interest in radio began as a teenager, and that extended into his time at the University of North Carolina. He served in the military after college, returning to take a job at an all-news station. 1236
