But in the days since, that exciting news melted into a pool of confusion after it became clear that the 90 percent figure came about from a complete accident. Now, experts are scratching their heads over what actually happened in the trial and what it means for the vaccine’s future. The Read More

We quickly started getting answers on some of these, but they were all imperfect in various ways. We could trace all the cases in controlled environments, like a cruise ship or Read More

Winter Weather, Holidays And Coronavirus Hoarding – A Recipe For

admin November 24, 2020

Share to Facebook Share to Twitter Share to Linkedin I live in the South. The mere mention of a winter weather threat induces an often irrational reaction. People flock to the stores to buy inordinate amounts of bread, milk, eggs, and other products. I often joke that French Toast is popular here during snow days. In reality, it is quite rare that an snow event in Georgia will cause people to be stranded for days in need of that much food. We are now entering our first winter within a Coronavirus pandemic, and two major holidays are approaching. How will Read More

Social media lit up with dramatic smartphone videos showing large crowds of workers pushing against guards in white hazmat suits in the airport’s parking structure. By Monday morning, local authorities grabbed hold of the situations, tweeting out videos of the 17,719 workers Read More

The announcement marks the third vaccine to show strong efficacy in late-stage trials against the pandemic coronavirus, SARS-CoV-2. Though AstraZeneca’s vaccine efficacy numbers are not as impressively high as those for the vaccines before it—mRNA vaccines from Pfizer/BioNTech and Moderna—AstraZeneca's does offer some advantages over those vaccines. In all, the Read More

Archaeologists find two more bodies among the ruins of Pompeii

EnlargeReuters Archaeologists found the remains of two men lying in an underground room in a large villa on the outskirts of the Roman city of Pompeii, in southern Italy, Reuters reports. Based on the condition of their skeletons and clues from preserved traces of clothing, one man appears to have been a wealthy person in his 30s, while the other was likely a slave or laborer in his early 20s. They died together at the villa of Civita Giuliana, probably while trying to flee or seek better shelter from a dense, fast-moving cloud of superheated volcanic gas and ash. The Read More

It was the wee hours of Thanksgiving morning in 1991. Up in space, the crew members on board space shuttle Atlantis were sleeping. Now all of a sudden, Lead Flight Director Milt Heflin faced a crisis. The flight dynamics officer in Mission Control informed Heflin that the Cheyenne Mountain Air Force Station, which tracked orbital traffic, had called to warn that a dormant Read More

Why are nuclear plants so expensive? Safety’s only part of

admin November 21, 2020

EnlargeUS DOE Should any discussion of nuclear power go on for long enough, it becomes inevitable that someone will rant that the only reason they've become unaffordable is a proliferation of safety regulations. The argument is rarely (if ever) fleshed out—no specific regulation is ever identified as problematic, and there seems to be no consideration given to the fact that we might have learned something at, say, Fukushima that might merit addressing through regulations. But there's now a paper out that provides some empirical evidence that safety changes have contributed to the cost of building new nuclear Read More
