what the researchers:

    (CNN)After years of examining centuries-old writings and digging up artifacts, researchers recently confirmed that an 18th-century building on the College of William & Mary campus was once a school for free and enslaved Black children. The building in Williamsburg, Virginia, that formerly housed the Bray School is thought to be the oldest building in the US dedicated to the education of Black children -- but the lessons students learned there were designed to reinforce slavery, historians said. Now, William & Mary and the Colonial Williamsburg Foundation are relocating and restoring the building together, an effort historians from both institutions hope will fill in a crucial piece of Black history previously missing from studies of the famous settlement. "[Its discovery] comes at a time when we so desperately need to tell the full history of early America," said Ronald Hurst, vice president of museums, preservation and historic resources at the Colonial...
    What is the potential of collaborative innovation and what challenges must companies face to innovate together? It is to answer these questions that the Coo-innov chair (for “Coopétition” and “Ecosystem of innovation”) at the University of Montpellier was created in February 2020. It brings together around fifteen teacher-researchers and doctoral students from the University of Montpellier and Montpellier Business School. “We can no longer do innovation alone in today’s world because it requires budgets, knowledge, etc., observe Frédéric Le Roy and Anne-Sophie Fernandez, teachers at the University of Montpellier Management, researchers in the Montpellier Research Management laboratory, and co-directors of the Coo-innov chair. So collaborative innovation is developing more and more. See the example of the 1st Covid vaccine, designed by Pfizer and BioNTech. “ Benefits and risks Today, business innovation therefore involves the development of joint projects with partners of different kinds, whether they are suppliers, universities, start-ups....

The visit has been shrouded in secrecy, with neither China nor the WHO revealing exactly what the team will do or where it will go. The search for the origins is likely to be a years-long effort that could help prevent future pandemics. Why Wuhan? The industrial and transportation hub on the Yangtze River is the first place the coronavirus surfaced in the world. It’s possible that the virus came to Wuhan undetected...
    A Greenpeace boat in Neko Harbour, Antarctica, on February 16. Alexandre Meneghini/Reuters On December 21, a Chilean research base in Antarctica reported the first cases of coronavirus on the remote continent. For months, Antarctica remained untouched by the virus, and researchers' lives had been as normal as pre-pandemic conditions. That life, which is met with freezing weather and dark winters, is no easy feat. Here's a look at what life is like in the research stations in Antarctica. Visit Insider's homepage for more stories. For months, one of the few places in the world without a single reported case of the coronavirus was the expansive, remote continent of Antarctica. That changed on Monday, when a Chilean research base reported 36 cases of COVID-19, local paper El Mercurio reported.  The 26 Army personnel and 10 civilian contractors who tested positive for the virus are in good condition and...
    Even as the COVID-19 pandemic continues to affect countries around the globe, researchers are hard at work trying to understand what happened and how such tragedies can either be prevented or mitigated in the future. Prominent among these efforts is a new spreadsheet developed by the London School of Hygiene & Tropical Medicine (LSHTM), where a team is attempting to track what are described as "ARS-CoV-2 Superspreading Events from Around the World" — and Colorado appears all too often on it. The document (accessible on Google Drive by clicking here), currently includes 137 superspread events in this state out of a total 1,521. As noted by Florida's Poynter Institute, which is touting the spreadsheet, the database provides information and brief descriptions about each event's location and whether it took place inside or outside, as well as geographic coordinates for mapping purposes. A wide range of countries is included, from Argentina and...
    (Reuters) - Here's what you need to know about the coronavirus right now: Fauci warns against vaccine roll-out before safety checks Distributing a COVID-19 vaccine under special emergency use guidelines before it has been proved safe and effective in large trials is a bad idea that could have a chilling effect on the testing of other vaccines, Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, told Reuters in a phone interview. "One of the potential dangers if you prematurely let a vaccine out is that it would make it difficult, if not impossible, for the other vaccines to enrol people in their trial," Fauci said. Fauci said the U.S. Food and Drug Administration guidance on vaccines - both for full approval and for an EUA (emergency use authorization) - explicitly requires a demonstration that it is both safe and effective.

    These very low temperatures require clear skies and the air to be extremely dry as well, because water vapor blocks heat loss from the snow’s surface. In addition, the high elevation of the eastern Antarctic plateau also favors these extreme conditions: the researchers observed that snow surface temperatures regularly dropped below -90 degrees Celsius almost every winter in a wide region of the plateau, at more than 3500 meters above sea level. Within this broad region, they found that dozens of sites had much colder temperatures. Almost 100 places reached surface temperatures of -98 degrees Celsius. The researchers observed the ultra-low temperatures in small drops or shallow hollows in the Antarctic ice sheet, where cold, dense, descending air collects above the surface and can linger for several days. This allows the surface, and the air above it, to cool even more, until the clear, calm and dry conditions break...
    In fact, in 2013, researchers at the University of Michigan looked at the electrical signals inside the brains of nine anesthetized rats after being induced to have a heart attack. Brief moments after clinical death, The researchers observed patterns of activity in the brain related to a state of ‘hyper alert’. During a heart attack, a clogged artery prevents blood from reaching part of the heart, which can cause that section to die, even though the heart continues to beat. As a result, the electrical signals that control the pumping action of the heart are disrupted, the heart stops beating, and death occurs soon after. The cerebral cortex, the ‘thinking part’ of the brain, is also instantly down, meaning that no brain waves, at least visible on a monitor, are produced for about 20 seconds. This first reaction starts a chain of cellular processes that results in brain death. But,...
    Coronavirus — This is the most effective mask against covid-19 1:24 . –– The use of face masks and coatings is recommended ––and in some places mandatory–– in public spaces to help stop the spread of covid-19. But what type of fabric (or homemade) mask offers the best protection? Researchers at Florida Atlantic University conducted experiments with different materials and styles of masks that are not for medical use, and found that a well-fitted face mask made from two layers of padded fabric was most effective in stopping the spread of cough drops and simulated sneezes. The experiment also compared a slightly folded home mask – like what you can do with a scarf or a T-shirt -, a bandana-type face covering, and a non-sterile conical-style commercial mask that is generally available at drugstores. Covid-19: what is the efficiency of wearing masks? 0:45 The researchers explained that they...
    Stimulus checks and expanded unemployment payments could help keep America’s poverty rate around where it was before the coronavirus outbreak — as long as enough people can access the money. That’s according to new research from Columbia University digging into the “promises and pitfalls” of the Coronavirus Aid, Relief and Economic Security (CARES) Act, the $2.2 trillion dollar stimulus bill that lawmakers passed in March to quickly get cash to families and businesses faltering from the pandemic. One measure of poverty would have climbed from an estimated 12.5% rate to 16.3% without any sort of federal intervention, the researchers said. (Great Recession-era levels peaked at approximately 16%, according to U.S. Census Bureau data.) But because of the money from stimulus checks and expanded unemployment, that poverty rate stayed at an estimated 12.7%, the Columbia researchers projected.
