The Food and Drug Administration on Wednesday authorized the first rapid coronavirus test that doesn’t need any special computer equipment to get results.The 15-minute test from Abbott Laboratories will sell for , giving it a competitive edge over similar tests that need to be popped into a small machine. The size of a credit card, the self-contained test is based on the same technology used to test for the flu, strep throat and other infections.It’s the latest cheaper, simpler test to hit the U.S. market, providing new options to expand testing as schools and businesses struggle to reopen and flu season approaches. The FDA also recently greenlighted a saliva test from Yale University that bypasses some of the supplies that have led to testing bottlenecks.Both tests have limitations and neither can be done at home. Several companies are developing rapid, at-home tests, but none have yet won approval. Abbott’s new test still requires a nasal swab by a health worker, like most older coronavirus tests. The Yale saliva test eliminates the need for a swab, but can only be run at high-grade laboratories.And in general, rapid tests like Abbott’s are less accurate than lab-developed tests. The FDA said in a statement announcing the decision that negative results with Abbott’s test may need to be confirmed with a lab test in some cases. The agency granted Abbott’s test an emergency use authorization late Wednesday for patients with suspected COVID-19.The two additions should help expand the number of available tests. The U.S. is now testing about 690,000 people per day, down from a peak of 850,000 daily tests late last month. Many public health experts believe the country will soon need to test vastly more people to find those who are infected, isolate them and contain the virus.The FDA noted that Abbott’s test could be used in a doctor’s office, emergency room or some schools. “Given the simple nature of this test, it is likely that these tests could be made broadly available,” the FDA said.Since the start of the pandemic, nasal swab tests that are sent to a lab have been the standard for COVID-19 screening. While considered highly accurate, the tests rely on expensive, specialized machines and chemicals. Shortages of those supplies have led to repeated delays in reporting results, especially during a spike in cases last month.Government and health experts view rapid tests that can be run outside the laboratory system as key to boosting capacity.“Those screening tests are what we need in schools, workplaces and nursing homes in order to catch asymptomatic spreaders,” said Dr. Jonathan Quick of the Rockefeller Foundation, in an interview earlier this month. The nonprofit group has called for the U.S. to conduct about 4 millions per day by October, mostly rapid, point-of-care tests.Abbott’s BinaxNOW is the fourth rapid test that detects COVID-19 antigens, proteins found on the surface of the coronavirus, rather than the virus itself. It’s considered a faster, though sometimes less precise, screening method. The other tests need to be inserted into a small machine.Inside the Abbott test is a specially coated strip that interacts with COVID-19 antigens. The patient’s nasal swab is inserted into the card and a few drops of a chemical solution are added. Markings appear on the card to indicate whether the sample is positive or negative — much like a pregnancy test.Two other makers of antigen tests — Quidel and Becton Dickinson have said they haven’t been able to meet demand for the tests. A third, LumiraDx, plans to begin shipping its recently approved antigen tests by the end of this month. Abbott expects to begin shipping tests in September, reaching 50 million tests a month in October.The influx of antigen tests will go a long way toward meeting the Trump administration’s projection that 90 million COVID-19 tests a month will be available by September if needed. But U.S. “testing czar” Adm. Brett Giroir has stressed that the U.S. can contain the outbreak with far fewer tests.“That’s the capacity ... we do not need that many tests to safely and sensibly reopen,” Giroir told reporters on a recent call. He pointed to several key indicators that have been falling, including new infections and hospitalizations, even as testing has slowed.Earlier this month, the FDA authorized Yale’s saliva-based test, which is expected to cut the time and cost compared with similar tests. It’s the fifth COVID-19 saliva tests OK’d by regulators. All require lab processing.Developed by Yale’s School of Public Health, SalivaDirect can use any sterile container to collect a sample, not the special tube needed with earlier tests, and requires less chemicals. Outside experts welcomed the new approach but noted its limitations.“It’s not a rapid test, it’s a laboratory-based test that will still be prone to the same massive delays as any other test,” said Dr. Michael Mina of Harvard University.___Follow Matthew Perrone on Twitter: @ AP_FDAwriter.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The Democratic National Committee is suing the Trump campaign, Russia, WikiLeaks founder Julian Assange and several associates of President Donald Trump alleging a grand racketeering, hacking and fraudulent conspiracy that harmed Democrats through WikiLeaks' publication of internal party emails during the 2016 presidential campaign.Those named in the lawsuit include several top Trump advisers who attended the now-infamous June 2016 meeting in Trump Tower, longtime Trump confidant Roger Stone, former Trump campaign chairman Paul Manafort and former campaign adviser George Papadopoulos and others.The 66-page lawsuit filed in Manhattan federal court on Friday lays out how the Trumps curried favor in Russia through their family business, and then Russia allegedly worked with Trump advisers before the presidential election to disseminate the spoils from a cyberattack of the DNC.The Democratic Party says the conspiracy and the hacking hurt their relationship with voters, chilled donations, disrupted their political convention and subjected their staffers to harassment. The lawsuit outlines nearly every known communication between Trump advisers and Russians.The Washington Post first reported the lawsuit.Special counsel Robert Mueller was appointed by Deputy Attorney General Rod Rosenstein last year to investigate Russian efforts to interfere in the 2016 election. As part of that mandate, Mueller is empowered to investigate any links between the Russian government and Trump campaign associates.The US intelligence community has concluded that Russian President Vladimir Putin ordered "an influence campaign" in 2016 with the goal of undermining public confidence in the US democratic process and eroding Hillary Clinton's chances of winning the presidency.Trump, however, has repeatedly insisted that there was no collusion between his campaign and the Russians, and has denounced the special counsel investigation as a "witch hunt."In the summer of 2016, the Democratic National Committee went public with claims that Russians hackers had gained access to their computer systems, obtaining emails and opposition research against Trump.Then, just days before the Democratic National Convention when Clinton was set to receive the party's presidential nomination, WikiLeaks published tens of thousands of hacked DNC emails.The release of the emails, which included messages disparaging Bernie Sanders, threw the Democratic Party into turmoil at a moment when the party was supposed to be coming together in support of a nominee, and intensified in-fighting between supporters of Clinton and Sanders.  2630

  

The flower fields have been around for 50 years. The Flower Fields are owned and operated by the Ecke Family, the onsite grower and floral sales is handled by Mellano and Company. They share their passion for beauty and expertise inthe flower business, with a combined experience of 100 years.The Flowers Fields are known all over the world. There is no other place like it with over 50 acres of ranunculus flowers in 13 different colors. The flowers are delicate, its seed is tiny, paper thin, and smaller than an oat flake. The seed has to be mixed with water and sand, then it is placed in a cooler for two weeks to trick the seed into thinking it had a winter. Ranunculus do best in temperate climate. Morning fog, cool mornings, and temperatures in the 50s and 60s help the flower production. The flower fields are ecofriendly, they use a drip irrigation system. It places water exactly where the seed is, using the water needed and not more than that.Extreme temperatures can be costly and one of the biggest threats to the crop. Winter warm ups are less than ideal but too much rain is also bad. The team at the Flower Fields has learned to tackle the weather, but every year presents new challenges. This year they are expecting the best season yet, you can visit the Flower Fields through Mother’s Day weekend. Next year expect a new color to be added to the already beautiful fields. 1402

  

The Food and Drug Administration warned pregnant women on Thursday of using some pain and fever medications during the second half of pregnancies.According to the FDA, these nonsteroidal anti-inflammatory drugs can cause rare but serious kidney problems in the unborn baby, which can cause pregnancy-related complications. Nonsteroidal anti-inflammatory drugs include ibuprofen, naproxen, diclofenac, and celecoxib. The FDA added that its warning does not apply to low-dose aspirin.“It is important that women understand the benefits and risks of the medications they may take over the course of their pregnancy,” said Patrizia Cavazzoni, M.D., acting director of FDA’s Center for Drug Evaluation and Research. “To this end, the agency is using its regulatory authority to inform women and their health care providers about the risks if NSAIDs are used after around 20 weeks of pregnancy and beyond.”The FDA says that warnings on prescription nonsteroidal anti-inflammatory drugs already advise of complications past 30 weeks. The newest guidance calls on health care providers to only prescribe the lowest effective dose for the shortest period possible for women 20 to 30 weeks into their pregnancy.More information on the warning can be found here. 1259
