WASHINGTON, D.C. — A home test for COVID-19 will soon be on U.S. store shelves.The U.S. Food and Drug Administration (FDA) on Tuesday issued an emergency use authorization for the first kit that consumers can buy without a prescription to test themselves entirely at home.Regulators granted use for a similar home test last month, but it requires a doctor’s prescription.The new test kit from Australian company Ellume allows users to swab themselves and get the results at home in about 20 minutes.The test detects fragments of proteins of the coronavirus from a nasal swab sample from anyone 2 years old and up. It connect to a digital app to help users interpret the results.Similar to other antigen tests, the FDA says a small percentage of positive and negative results from this test may be false. Therefore, for patients without symptoms, positive results should be treated as presumptively positive until confirmed by another test as soon as possible.Individuals with positive results should self-isolate and seek additional care from their health care provider. Those who test negative and experience COVID-like symptoms should follow up with their health care provider as negative results do not preclude an individual from coronavirus infection.The company says it will have 3 million tests available next month.“The FDA strongly supports innovation in test development and we have worked tirelessly with test developers to support the shared goal of getting more accurate and reliable tests to Americans who need them. Today is a promising step forward and we are eager to continue advancing additional innovation in COVID-19 testing that the science supports,” said Jeff Shuren, M.D., J.D., director of FDA’s Center for Devices and Radiological Health. 1773

We see them everywhere. People are flying them all over the place, but there's a more serious, nefarious side to what should just be fun.Hackers are turning drones into devices that steal our personal information."It's got a bunch of peripherals…to hack basically anything over the air," Francis Brown, co-founder of Bishop Fox, said.Brown works to find holes in other companies' security systems. He says drones are now taking the bad guys where they're usually not allowed to go."Anything within the vicinity that's speaking over the air that's kind of an ideal platform to kind of just go land to do a drive by outside the window or go land on the roof and then hack something over the air, Brown said."Hackers attach a little computer called a Raspberry Pi to a drone. It looks like a big computer chip and then it's just flown around."These quad copters basically are little laptops with hacker tools on them," Brown said.Wireless, Blue Tooth, and R-F-I-D signals are all vulnerable, these drone can access places a normal hacker couldn't even reach."Buildings that are centrally located inside a corporate campus. There are you know near the street buildings where you couldn't necessarily see the Wi-Fi from the parking lot because it's a secure campus lesser or a wireless in a conference room on the 50th floor that witnesses are going to get from the ground,"  Brown said. So how often is this happening? Brown says it's tough to track, because companies are embarrassed to say if they've been hacked this way. He says the threat alone, should be a wake up call."One of the biggest advantages from a hacker's perspective is that it reduces your chances of getting caught is even more brazen," Brown said.Brown says anyone could be targeted, from an office park to your neighborhood block preventing drones from being there is extremely difficult.  Signal blockers in those frequencies to stop the drones from flying are illegal. 1961

WASHINGTON, D.C. – President Donald Trump and the first lady were greeted with boos Thursday as they visited the Supreme Court to pay their respects to the late Justice Ruth Bader Ginsburg.As Trump stood next to the justice's casket, a crowd chanted “vote him out” and “honor her wish,” referring to Ginsburg’s request that the next president should fill her open seat.Just days before her death, Ginsburg’s granddaughter, Clara Spera, says the justice dictated this statement to her, “My most fervent wish is that I will not be replaced until a new president is installed.”Ginsburg died last week at the age of 87. She is currently lying in repose at the Supreme Court for a second day.The president will announce his candidate to replace Ginsburg on Saturday. His decision to name a candidate and the Senate’s decision to quickly hold hearings ahead of the November 3 election has sparked controversy.Hundreds of mourners passed by her coffin Wednesday outside the Supreme Court, following a ceremony including Ginsburg’s family, close friends, colleagues from the court, and more than 100 former law clerks.Friday, Ginsburg’s coffin will be moved to the U.S Capitol, where she will become the first woman to lie in state since the honor started in 1852.A private graveside ceremony will be held next week at Arlington National Cemetery. 1347

  

WASHINGTON (AP) — President Donald Trump is insisting the Navy “will NOT be taking away Warfighter and Navy Seal Eddie Gallagher’s Trident Pin” that designates him a SEAL.Attorneys for Chief Petty Officer Edward Gallagher had accused the Navy of trying to remove the designation in retaliation for Trump’s decision last week to restore Gallagher’s rank.Gallagher was acquitted of a murder charge in the stabbing death of an Islamic State militant captive, but a military jury convicted him of posing with the corpse while in Iraq in 2017. He was demoted to chief.Trump tweeted, “This case was handled very badly from the beginning” and urged those involved to “Get back to business!”Gallagher filed a complaint with the inspector general accusing a rear admiral of insubordination for defying Trump’s actions. 817

  

Wednesday was the first full day of class for students at Marjory Stoneman Douglas High School since the Feb. 14 shooting killed 17 people at the Broward County school. FULL COVERAGE: Parkland school shootingSince returning to class on Feb. 28, the school had been on a modified schedule. Wednesday's classes ended at 2:40 p.m."The mood is like sad, emotional," Sebastian Benitez, a freshman at Stoneman Douglas said. "People are happy to see their friends but it’s still hard to think about all those lives that were lost.”U.S. Education Secretary Betsy DeVos was on campus meeting with students and teachers. The meeting might give her more insight as she continues her broader talks on how to prevent such a tragedy from happening again. DeVos has said she is open to allowing guns in schools but says the decision should be left to local communities.President Trump is in favor of arming teachers, saying that too many of these shootings happen in gun free zones.“A gun-free zone is, ‘Let’s go in and let’s attack, because bullets aren’t coming back at us,'” Trump said.Students at Stoneman Douglas have been vocal for change since the shooting last month. Their rallies were heard loudly and they have put pressure on lawmakers to enact gun reform during their visits to Tallahassee and during school walkouts. During a news conference, DeVos gave credit to the students for finding their voice and for taking interest in seeing what adults are going to do in response to the massacre. "People across the country in states and communities have addressed some of the concerns, some of the issues that have arisen here," DeVos said. "But we need to help elevate those opportunities and make sure people know there are solutions that can be engaged immediately."When pressed about the solutions she referenced, the secretary did not offer specifics. DeVos did however say she was looking forward to returning to the school in the future.  2033
