Trump On The Look Out of Doing Something Bad For The Most People Cancels Grants to EcoHealth Alliance

If he (Trump) does not understand it he won't let the government contribute, even if it means finding out how Covid-19 came about. As far as he is concern the pill in which he has put personal resources(a pill that kills lots more than helps, Hydroxychloroquine) and a vaccine from Moderna which is run by his pals and which the CDC has very little faith on the method being used and the speed in which they want to bring it to the market. I guess as far as he is concern the Coronavirus is almost over with his help and investments he is the hero.
This Bornean horseshoe bat and other bat species can harbor coronaviruses. The nonprofit group EcoHealth Alliance had U.S. government funding for an ongoing research project in China on bats and coronaviruses — until the money was cut on April 24.

In an open letter to a top Trump Administration official, 77 Nobel prize-winning American scientists say they are "gravely concerned" about the recent abrupt cancellation of a federal grant to a U.S. non-profit that was researching coronaviruses in China. The laureates say that the move, announced on April 24, "sets a dangerous precedent by interfering in the conduct of science" and "deprives the nation and the world of highly regarded science that could help control one of the greatest health crises in modern history and those that may arise in the future."
The research group in question, EcoHealth Alliance, specializes in hunting viruses worldwide. For years their scientists have been trapping bats in China in order to check their blood and saliva for new coronaviruses that could spark the next pandemic in humans. Last year the National Institutes of Health renewed funding for that project – granting EcoHealth Alliance $4 million to cover the next five years of research.
Then, last month, various U.S. officials began working to raise suspicions that a local Chinese lab that EcoHealth Alliance had partnered with – the Wuhan Institute of Virology—had accidentally released the virus causing COVID-19. (The Institute is located in the Chinese city where the current pandemic began.) 

Multiple virologists who are familiar with lab accidents as well as the way that coronavirus research is conducted have discounted the accident theory as nearly impossible. Yet a few days after a White House press conference at which President Trump promised action on the issue – and erroneously implied that the entirety of the grant had gone to the Wuhan Institute — NIH terminated the funding.
EcoHealth Alliance's president Peter Daszak has told NPR that as a result, his group hasn't just lost the ability to look for new viruses in China. They — and the many international researchers with whom they share their data – have also lost access to the vast collection of distinct coronavirus samples already collected. These include around 50 from a category that caused the 2002 outbreak of severe acute respiratory syndrome, or SARS, and, now, the COVID-19 pandemic. 
In an email informing EcoHealth of the grant termination, an NIH official said the reason was that the project did not align with NIH goals and priorities. In their letter Friday, the 77 Nobel laureates dismiss this as "preposterous." The writers – who are from the fields of medicine, chemistry and physics and represent honorees from nearly every year since 1975 — note that EcoHealth's grant application had received "a very high priority score" during peer review. And they add, "now is precisely the time when we need to support this kind of research if we aim to control the pandemic and prevent subsequent ones."
The letter is addressed to not only the head of the NIH but to the Trump-appointed cabinet member who oversees the agency — Secretary of Health and Human Services Alex Azar. The laureates conclude with a call for a "thorough review of the actions that led to the decision to terminate the grant" and "appropriate steps to rectify the injustices that may have been committed in revoking it."

On Thin Ice: Why Ice Loss Matters {Vid by NASA}

Over 90% of Earth’s ice mass is locked up in Greenland and Antarctica. As our greenhouse gas emissions warm the planet, those areas, along with glaciers worldwide, lose more ice, contributing to sea level rise. Watch the video to learn how many people are threatened by this phenomenon worldwide and how much global sea level is projected to rise by 2100.

This Diamond Shows There is an Ocean of Underneath the Earth

In what sounds like a chapter from Journey to the Centre of the Earth, the chemical makeup of a tiny, extremely rare gemstone has made researchers think that there are oceans that exist hundreds of miles beneath the Earth.
The gemstone in question is called ringwoodite, which is created when olivine, a material that is extremely common in the mantle, is highly pressurized; when it’s exposed to less pressurized environments, it reverts into olivine. It has previously been seen in meteorites and created in a laboratory, but until now had never been found in a sample of the Earth’s mantle. 
Diamond expert Graham Pearson of the University of Alberta came across a seemingly worthless, 3 millimeter piece of brown diamond that had been found in Mato Grosso, Brazil while he was researching another type of mineral. Within that diamond, he and his team found ringwoodite—and they found that roughly 1.5 percent of the ringwoodite’s weight was made up of trapped water. The findingsare published in Nature.
That water had to get in there somehow, and, using analyses of its depth and its water makeup, Pearson suggests that there's water deep beneath the Earth's surface—a lot of it. 
The finding “confirms predictions from high-pressure laboratory experiments that a water reservoir comparable in size to all the oceans combined is hidden deep in Earth’s mantle,” according to an analysis of Pearson’s findings by Hans Keppler of the University of Bayreuth in Germany. 
The Earth’s crust, including the deepest parts of the oceans, reach depths of roughly 100 kilometers. From there, the upper mantle takes up about another 300 kilometers. Between there and the lower mantle is where this piece of ringwoodite was originally from—an area between 410 and 660 kilometers beneath the Earth’s surface known as the “transition zone.” 
Scientists have long been divided about what, exactly, is in the transition zone. We’ve known that much of the upper mantle is made up of olivine, and, as Keppler said, scientists have long thought that Earth contained reservoirs of water deep beneath the crust. But they weren’t sure whether the water existed as low as the transition zone—the area between the upper and lower mantles. While some say that much of the oceans’ water may have originated there, others have said it is likely completely dry.

Pearson’s finding changes that. In the paper, he says that there are two possible explanations for water within the ringwoodite.
“In one, water within the ringwoodite reflects inheritance from a hydrous, diamond-forming fluid, from which the inclusion grew as a syngenetic phase. In this model, the hydrous fluid must originate locally, from the transition zone, because there is no evidence that the lower mantle contains a significant amount of water,” he wrote. Essentially, the extreme pressure and chemical makeup at those depths spontaneously creates water. 
“Alternatively, the ringwoodite is ‘protogenetic,’ that is, it was present before encapsulation by the diamond and its water content reflects that of the ambient transition zone," Pearson wrote. In that model, the water and the ringwoodite are already there, and the ringwoodite absorbs some of the water. Either way you slice it, there is a lot of water in the transition zone: “Both models implicate a transition zone that is at least locally water-rich,” he wrote.
So, how does a piece of ringwoodite that’s from at least 410 miles beneath the surface get up to a riverbed in Brazil? According to Keppler—and the fact that Pearson was looking for volcanic rocks—suggests that something, probably a volcanic eruption, quickly pushed it up to the surface. It was just a coincidence that Pearson was able to analyze it before the ringwoodite turned back into its non pressurized form. 
“It was a piece of luck, this discovery, as are many scientific discoveries,” Pearson said. 
And now we can imagine oceans beneath the oceans, where fantasy beings could exist.

Want to See The Earth Breathe For Real? NASA Makes Available Here

Wanna See the Earth Breathe for Real? Watch This Stunning GIF

Images laced together from NASA’s Visible Earth show the cycling seasons of our planet reduced to just a few seconds of ceaseless movement.

You can almost hear it sigh. Our third rock from the sun inhaling the solid ice of winter and exhaling in the heat of summer, as the world keeps turning and spinning.
John Nelson, a user-experience expert for the software firm IDV Solutions, posted this GIF, which laces together NASA's Visible Earthimages. The GIF is made up of 12 NASA photographs, one taken each month in 2004.
The GIF reveals the dramatic way Earth freezes over each season, only to thaw into the infinite blue deep in the warmth of a summer sun.
Unfortunately, climate change has the power to skew the yin-yang balance. Unprecedented Arctic ice cap loss could tip the scale in favor of the great watery drink, to the detriment of human and fauna alike.
