Abbott Launches 5-Minute Covid-19
Test for Use Almost Anywhere

Original Article

Abbott Laboratories is unveiling a coronavirus test that can tell if someone is infected in as little as 5 minutes, and is so small and portable it can be used in almost any health-care setting. The medical-device maker plans to supply 50,000 tests a day starting April 1, said John Frels, vice president of research and development at Abbott Diagnostics. The molecular test looks for fragments of the coronavirus genome, which can be detected in as little as five minutes when it’s present at high levels. A thorough search to definitively rule out an infection can take up to 13 minutes, he said.

Biotech breakthroughs, being applied to a new virus. Very cool. Apparently a fast, automated PCR-based test. Note that they quote a bit longer time for lower blood concentrations? They are cycling the system, doing PCR and exponentially multiplying the target fragment, cycle by cycle. Cool!

PCR in 5 - 15 min? Amazing! Best of luck with this project (and I don't care if a few clever folk exceed Bernie Sander's income threshold for scorn, ridicule and wealth confiscation).

#3, It seems like that is what they are doing. The info from the article says: "The molecular test looks for fragments of the coronavirus genome, which can quickly be detected when present at high levels. A thorough search to definitively rule out an infection can take up to 13 minutes, he said." Sounds to me like PCR amplification of the key fragments. If at low levels, say maybe 4 doubling cycles needed get 32X amplification and to reach detectable level , but at lower concentration in the sample, run, say 4 added cycles and increase concentration by a total factor of 1024X. The cycle time must be quite short, amazing.

Will the EU survive coronavirus? 25 replies

Will the European Union be one of the casualties of COVID-19? The worldwide pandemic has dealt a dramatic and obvious blow to the liberal ideas of free trade and freedom of movement that inspired and were inspired by the EU. The openness that made it possible to travel and do business seamlessly across a continent has provided the virus with a cornucopia of vectors for transmission. If the refugee crisis of the mid-2010s put strengthened borders back on the continent's political agenda, the pandemic has made the case for hunkering down nationally as well as individually hard to dispute.

NORTH HAVEN, Maine—The ferry to the island of North Haven, Maine, has space for a dozen or so vehicles and 220 passengers. This past Saturday afternoon, there were just three passengers: a cable operator on his way to check the island’s Internet service, and a lobsterman and his sternman returning from a supply run. They made the 12-mile crossing inside their trucks, opting not to venture into the ferry’s empty passenger compartments. About 75 minutes later, they docked at the town landing where a single car waited to depart. Normally, this time of year, the 12:30 p.m. ferry runs about half full.

CHAMBERSBURG, Pennsylvania — It is early Sunday morning along one of the few congested stretches of the Lincoln Highway when an empty parking lot below the familiar cheery yellow sign for the local Waffle House catches the eye. The 24-hour diner chain, born in Atlanta 65 years ago and now spread across 25 states in nearly 2,000 locations, is primarily known for its ability to serve as a touchstone in every community it serves. It feeds a cult-like following among foodies and road warriors. But it is also known for two other very remarkable distinctions: It closes for no disaster, and the stores have no locks.

  Back home in Oakland, Calif., Lisa Pezzino and Kit Center built a life that revolved around music and the people who make it — the musicians who recorded on Pezzino’s small label and performed in places where Center rigged the lights and sound equipment. Where they are now, deep in the redwood forest near Big Sur, 140 miles south along the California coast, there is mostly the towering silence of isolation. A tiny cabin, an outdoor kitchen, just one neighbor. This is life in the flight from the virus.

Covid-19: The Reality Show has taken cable TV by storm. The plot is nominally about a war against an invisible Chinese invader that has already killed over 1,200 Americans. But on another level, it is a family sitcom, a successor to Ozzie and Harriet, Leave It to Beaver, and The Cosby Show. The star is Daddy Donald, a brilliant if erratic father figure, who sometimes rambles on, as fathers are wont to do. He is ably supported by his younger brother, Uncle Mike, who is loyal, steady, competent, and boring. With every strand of his snow-white hair perfectly in place, Uncle Mike always says the right thing.

It is a given in politics that an incumbent has the advantage until things go wrong, at which point the challenger gets an edge. Then why, amidst panic, death and economic shutdown, is Joe Biden looking like the sick man of 2020? Biden’s predicament is odd considering a key pillar of Donald Trump’s presidency — record low unemployment — is being vaporized. Thursday’s 3.3 million new unemployment claims wiped out nearly half the jobs created in the last three years, and the worst is yet to come.

The World Health Organization (WHO) is being accused of "carrying China's water" after a senior adviser refused to acknowledge Taiwan during a bizarre interview with a Hong Kong news outlet. Canadian physician Dr. Bruce Aylward, an aide to WHO director-general Dr.Tedros Adhanom, sat down for a video interview with RTHK about the coronavirus outbreak where he was asked whether the organization would "consider Taiwan's membership." For several seconds, Aylward sat in silence. "Hello?" the reporter asked.

Prime Minister Netanyahu’s astonishing emergence with an agreement to remain the prime minister in a national unity government of Israel reminds us of the yarn about the rabbi, the cossack, and the cossack’s dog. It seems the rabbi is out for a walk when he encounters a cossack officer and his dog. The cossack draws his weapon, points it at the rabbi, and pulls back the hammer. “Don’t shoot, don’t shoot,” the rabbi cries, throwing up his arms. “Why not?” demands the cossack. “Because,” the rabbi exclaims, “if you give me a year, I will teach your dog to talk.”

The coronavirus crisis is a make-or-break moment for the American media. According to Wednesday’s Gallup poll on the coronavirus response, “Hospitals Rated Best, News Media Worst.” The survey shows that 44% of the public says the media has been doing “a good job.” This is high considering how the press fares in normal times, but let’s be honest: It can’t be comforting to a press corps that has been persistently adversarial to Donald Trump that it ranks 16 points lower than the approval of the president’s own handling of the crisis. Predictably, some of the media’s worst tendencies, such as myopic concerns about political correctness and electoral politics, have often

New York Governor Andy Cuomo, like President Trump, is delivering daily coronavirus briefings. Unlike President Trump, he is being swooned over by liberal reporters. At American Greatness, Julie Kelly collects some examples. Here is just one: “If social media is a reflection of how people are feeling, Cuomo’s image during the coronavirus outbreak is one of authority, yet hope—a role people value enough to begin visualizing his presidency,” one smitten CBS News reporter cooed. This is odd, if only because New York is the epicenter of COVID-19 infection in the U.S. The disease is more widespread there, and more problematic, than anywhere else.

Pelosi said, “First let me say how sad it is that even since the president’s signing of the bill, the number of deaths reported has doubled from 1,000 to 2,000 in our country. This is such a very, very sad time for us. We should be taking every precaution. The president, his denial at the beginning, was deadly.

Prince Harry 'regretted' having to stand down from his role in the military, and felt 'forced into it' after stepping down from royal duties, a source has claimed. The Duke of Sussex, 35, who decided to step back from the limelight with Meghan Markle, 38, and 10-month-old Archie after being subjected to intense scrutiny which brought back painful memories of Princess Diana's death, is said to have been apologetic about giving up his post as Captain General of The Royal Marines.

Whatever you think about President Trump and his response to this global pandemic that sparked from a Chinese “wet market” selling wildlife, you cannot exactly be heartened to behold the response offered by Democrats. The party’s presumed nominee, former Vice President Joseph R. Biden, finally mounted the barricades this week to personally combat the Wuhan virus by — what else? — setting up a television studio in his Delaware home to offer “counterprogramming” to the president and his crisis team of doctors, public health officials, industry leaders, and economic experts.

They are things that can’t continue. We are going to go through another phase of this. We have to be ahead of the curve, not behind like we were last time.” Host Chuck Todd asked,

Poll of the week: A new ABC News/Washington Post poll finds that President Donald Trump's approval rating among all adults in 48%, while his disapproval rating is 46%. Trump scores a very similar 49% approval rating and 47% disapproval rating with registered voters. What's the point: There's no doubt now that Trump is experiencing a bump in his popularity following his response to the coronavirus pandemic. The ABC News/Washington Post poll is quite similar to the Monmouth University poll that came out earlier this week, for instance. But what is interesting to me is that Trump's jump is coming disproportionality from non-voters. Normally Trump does considerably better among voters than among adults.
