NASA Invites Public to Be Its Guests to Celebrate Historic 'Launch America'

NASA is inviting the public to help celebrate a historic milestone in human spaceflight as it prepares for #LaunchAmerica – the first flight into orbit of American astronauts on American rockets from American soil since the end of the space shuttle era in 2011.

NASA’s SpaceX Demo-2 test flight, which is targeted for lift off at 4:33 p.m. EDT Wednesday, May 27, this mission will send NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station as part of the agency’s Commercial Crew Program. Members of the public can attend the launch virtually, receiving mission updates and opportunities normally received by on-site guests.

SpaceX will use this rocket for its first manned space launch on May 27th

The SpaceX Crew Dragon capsule will be first private spacecraft to carry astronauts into orbit.

The launch is the first time astronauts will launch into orbit aboard a spacecraft built by a private company.

This will be the first time American astronauts pilot an American-made spacecraft launched from U.S. soil since NASA's Space Shuttle program ended in 2011.

Two astronauts will travel to the International Space Station aboard the Crew Dragon, although the spacecraft can carry up to seven passengers.

Moderna stock jumps after a positive vaccine trial

An early trial of its coronavirus vaccine candidate produced positive results.  All 45 volunteers in the trial produced antibodies that may help protect them against COVID-19.  The company hopes to soon start a mid-stage study of the vaccine candidate after the phase-one trial and move to a late-stage trial in July.

Moderna is aiming to have a vaccine ready for emergency use in the fall — a timeline that has never been seen for vaccine development.

Evidence suggests sun entering 'solar minimum' stage

100 days since there were any recorded sunspots.  So far this year, the Sun has been blank 76 percent of the time.  Last year, 2019, the Sun was blank 77 percent of the time.  Two consecutive years of record-setting spotlessness adds up to a very deep solar minimum.  This is called a solar minimum, and it is a regular part of the sunspot cycle.

The sun’s magnetic field has become weak, allowing extra cosmic rays into the solar system.  Excess cosmic rays pose a health hazard to astronauts and polar air travelers, affect the electro-chemistry of Earth’s upper atmosphere and may help trigger lightning.

Ozone's Effectiveness in Killing SARS Coronavirus Leads to Theory on COVID-19

Ozone has been proven to kill 99.999 percent of pathogens in the air, including SARS Coronavirus and influenzas such as H5N1.  In past studies, 99 percent of viruses have been destroyed and showed damage to their envelope proteins after 30 seconds of exposure to ozone.  This can result in the virus's failure to attach to normal, healthy cells, and the breakdown of the single-stranded RNA can lead to the destruction of the virus.

Viruses are small particles made up of crystals.  Ozone destroys viruses by attacking the nucleic acid core, thus damaging the viral RNA.  After destroying these particles, ozone dissipates and leaves breathable oxygen as its only byproduct.  COVID-19 is an enveloped virus.

Using ozonated water for handwashing kills bacteria and viruses on impact.  Ozone is created by special generators that release it in the air for purification or infuse it into water for disinfecting surfaces.  More information about ozone generators and how they work can be found here.

See this build-it-yourself virus-killing ozone generator.

Why are there so few antivirals?

Antibiotics treat bacterial infections.  Bacteria are cellular.

Unlike bacteria, viruses cannot replicate independently outside a host cell.  There is a debate over whether they are really living organisms at all.

To replicate, viruses enter a host cell and hijack its machinery.  Once inside, some viruses lie dormant, some replicate slowly and leak from cells over a prolonged period, and others make so many copies that the host cell bursts and dies.  The newly replicated virus particles then disperse and infect new host cells.

Different viruses vary from each other much more than different bacteria do.  There is extreme diversity between different viruses. Some have DNA genomes while others have RNA genomes, and some are single-stranded while others are double-stranded.  This makes it practically impossible to create a broad spectrum antiviral drug that will work across different virus types...

Black hole only 1,000 light-years from Earth discovered

The newly discovered black hole is dubbed HR 6819.  The star system was only spotted after two companion stars provided researchers with information on its whereabouts.  It can be seen on a clear night in the Southern Hemisphere without the use of a binocular or telescope, making it the first black hole to be seen without tools.

Though the black hole itself is invisible (as all black holes are) and does not have violent interactions with objects around it, the researchers are nonetheless certain it's there.  “An invisible object with a mass at least 4 times that of the Sun can only be a black hole."

The discovery was published in Astronomy & Astrophysics

The artist’s impression below shows the orbits of the objects in the HR 6819 triple system.  This system is made up of an inner binary with one star (orbit in blue) and a newly discovered black hole (orbit in red), as well as a third object, another star, in a wider orbit (also in blue).  (Credit: ESO)

FDA allows emergency use of remdesivir to treat coronavirus patients after promising study

President Trump announced Friday that the Food and Drug Administration (FDA) has authorized the emergency use of Gilead Science's experimental antiviral drug remdesivir to treat coronavirus patients after early results of a clinical study indicated the drug helps speed recovery.  Trump announced the news at the White House alongside Gilead CEO Daniel O'Day and FDA Commissioner Stephen Hahn.

Dr. Anthony Fauci, the nation's top infectious disease expert and the director of the National Institute of Allergy and Infectious Diseases, praised the drug Wednesday.

Gilead touts 'positive data' on drug as coronavirus treatment

Gilead Sciences said "positive data" emerging from a clinical trial studying one of its drugs as a potential treatment for COVID-19.

The National Institute of Allergy and Infectious Diseases’ study of remdesivir, an experimental antiviral, has reached its primary endpoint, meaning the drug was found to be effective in the trial.

There is no proven COVID-19 treatment yet, though hundreds of clinical trials are ongoing all around the world to find one.  Scientists have high hopes for remdesivir, which was originally developed as a potential treatment for Ebola.

Gilead disputes report that its coronavirus drug failed in China trial

Gilead said the findings were inconclusive because the study was terminated early

Gilead Sciences is responding to a World Health Organization report that its experimental antiviral drug failed to help patients with severe COVID-19 in a clinical trial conducted in China.  Gilead coronavirus drug could still be promising despite leaked negative results.

"We believe the post included inappropriate characterizations of the study. The study was terminated early due to low enrollment and, as a result, it was underpowered to enable statistically meaningful conclusions," according to a Gilead statement.  "As such, the study results are inconclusive, though trends in the data suggest a potential benefit for remdesivir, particularly among patients treated early in disease."

See the Emory University COVID-19 self-triage tool

The tool is basically for anyone who believes that they may have COVID-19 based on their symptoms (e.g., loss of smell, shortness of breath, fever).

It is designed, in part, to prevent a surge of patients at hospitals and healthcare facilities.

If you think you may have COVID-19, the website can answer questions to help you determine the best course of action (anything from stay at home and rest to get immediate medical attention).

For more information, see this news release, Emory helps build free online tool to assess COVID-19 risk.

Coronavirus has 'reactivated' in more than 100 South Koreans who recovered

More than 100 South Koreans who fully recovered from coronavirus have tested positive for a second time. Last week there were 51 cases of patients testing positive after being cleared of the virus. There have been no cases of the relapsed patients spreading the virus to anyone else.

From the Wall Street Journal:

Q: Is it useful to take common-cold remedies to help fight the virus?

A: Experts say remedies such as DayQuil are helpful for controlling the virus's symptoms. But they aren't a cure and won't prevent you from infecting others.

Europe could be close to herd immunity from coronavirus ALREADY with 15% of people carrying antibodies say researchers studying city dubbed 'German Wuhan'

Two researchers from Göttingen University claimed countries have only spotted six per cent of all COVID-19 cases, on average. Rates - which the researchers said were true up to March 31 - were staggeringly low in Britain (1.2 per cent), Italy (3.5 per cent), Spain (1.7 per cent) and the US (1.6 per cent). Because of the huge disparity, they described the official tallies trotted out by health ministers across the world each day as 'rather meaningless'.

Up to 15 per cent of people in hard-hit German town may already have immunity. If 15 per cent of people do have antibodies, then Germany's actual death rate could be as low as 0.37 per cent. This is five times lower than the current calculated level.

"This means a gradual relaxation of the lockdown is now possible."

With far more people infected than previously thought, Europe as a whole could be closer to herd immunity than expected.

Army researchers at Fort Detrick who helped discover Ebola treatment seek coronavirus vaccine

These are the same army scientists who helped develop vaccines for anthrax, the plague and Ebola. Now, they have been working double shifts growing large amounts of the COVID-19 virus at this sprawling lab complex.

"We can test about 300 drugs or compounds in each plate."

They have used sneeze labs -- a technology the U.S. Army invented -- to test how the virus has spread through the air. "It would mimic you and I walking through someone's sneeze. There's a swirl of virus within droplets, so it doesn't exist just in air, but it's in fine droplets of many different sizes. Large droplets would land on your mouth and eyes, maybe on your hands, on surfaces, small droplets. You breathe them into your nostrils. Some of them make it past your projections, get deep into the lungs."

"We're going to find this vaccine and we're gonna win in the end."

FDA Authorizes Use of Malaria Drugs for Coronavirus

The emergency-use authorization is for two oral prescription drugs, hydroxychloroquine and chloroquine, which are used primarily to treat malaria, but are now being investigated by federal agencies. 30 million doses of hydroxychloroquine sulfate and one million doses of chloroquine phosphate have been donated. The FDA will allow the drugs to be distributed and prescribed by doctors to hospitalized teen and adult patients with COVID-19, as appropriate.

As of early Monday morning, the coronavirus has infected more than 143,000 people in the U.S. and at least 2,513 people have died from the respiratory illness.

Up to 10 percent of recovered coronavirus patients test positive again, China reports

As many as 10% of recovered coronavirus patients in China tested positive again after being discharged from the hospital, according to a report. So far there is no evidence to suggest that they are infectious. The five patients who tested positive again did not have any symptoms and none of their close contacts had been infected.

Surveillance of similar patients showed that 80 to 90% had no trace of the virus in their system one month after being discharged from the hospital.

Additionally, health officials around the world are testing the concept of taking plasma from someone who has been infected, processing it, and injecting the antibodies into a sick person to stimulate their immune system.

Is the Coronavirus as Deadly as They Say?

"Fear of Covid-19 is based on its high estimated case fatality rate—2% to 4% of people with confirmed Covid-19 have died, according to the World Health Organization and others. We believe that estimate is deeply flawed. The true fatality rate is the portion of those infected who die, not the deaths from identified positive cases."

The deaths from identified positive cases are “misleading” because of limited data.

"The real fatality rate could in fact be closer to 0.06%."

Death in the U.S. by the numbers

For 2017, the latest year for which there are numbers, there were 2,813,503 deaths.

That means there were an average of 7,708 deaths per day in the U.S.

From the first Wuhan virus death in the U.S., on February 29th, to date, there have been 624 deaths due to the Wuhan virus.

That means there were an average of 24.88 deaths per day in the U.S. due to the Wuhan virus.

Deaths from the Wuhan virus are 00.32 % of the total deaths per day in the U.S.

To put that number in perspective, the infant mortality rate in the U.S. is 00.58 %
– almost twice as high.

See the CDC Deaths and Mortality webpage for more information.

The date of the first U.S. Wuhan virus mortality was taken from this news article, and the total number of deaths in the U.S. was taken from here.

The Hidden Epidemic Behind COVID-19: Myths & Misinformation

Protective N95 face masks, regular hand-washing, avoiding any contact with the infected person, coughing and sneezing hygiene, adequate isolation of the affected are the measures suggested.

Death does not happen inevitably with COVID-19 infection. The mortality rate is only 2%, much lesser than the similar strains causing illness like SARS or MERS in the past. Majority of cases are mild infections and the number of uncomplicated cases are on the rise. Death occurs due to pulmonary complications, mainly pneumonia and respiratory failure.

In any case, death is NOT imminent with this virus.

EPA publishes a list of potent ammunition against coronavirus

The Environmental Protection Agency has published a list of disinfecting chemicals and products that have been verified to be effective against the coronavirus.

Because viruses are unique kinds of microorganisms, not all antibacterial products will have the same degree of effectiveness; however, the soaps and cleaners on this list are known to dissolve the virus's "envelope," or outer coating.

In a spot of good news, the EPA states enveloped viruses like SARS-CoV2 are among the easiest to kill using the products on the list. This is partially because the virus envelopes are composed of lipids, which are fatty, oily types of compounds.

Just how you can wash grease from pans, you can scrub away the virus’s shell with vigorous, soapy handwashing.

Notable names on the list include the following widely available cleaning products:

• Clorox Multi-Surface Cleaner + Bleach

• Clorox Disinfecting Wipes

• Clorox Commercial Solutions® Clorox® Disinfecting Spray

• Lysol brand Heavy-Duty Cleaner Disinfectant Concentrate

• Lysol Disinfectant Max Cover Mist

• Lysol brand Clean & Fresh Multi-Surface Cleaner

• Purell Professional Surface Disinfectant Wipes

• Sani-Prime Germicidal Spray

You can see the complete list here, courtesy of the EPA.

Neandertal birch tar-hafted tool proves abstract conceptualization ability
"The production of birch tar adhesives was a major technological development, demonstrating complex Neandertal technology and advanced cognitive ability."

Summary:

A tar-backed tool from the present-day North Sea reveals the use of complex technology by Neandertals.   This article reports the discovery of a 50,000-year-old birch tar-hafted flint tool found off the present-day coastline of The Netherlands.   The production of birch tar adhesives and multicomponent tools was a major technological development.   It is considered complex technology and has a prominent place in discussions about the evolution of human behavior.   This find provides evidence on the technological capabilities of Neandertals and illuminates the currently debated conditions under which these technologies could be maintained.   The find demonstrates that birch tar was a routine part of the Neandertal technological repertoire.   Dating the geological provenance of the artifact firmly associates it with a host of Middle Paleolithic stone tools and a Neandertal fossil.   The object is a piece of birch tar, encompassing one-third of a flint flake.   This find demonstrates that Neandertals mastered complex adhesive production strategies and composite tool use.   The discovery also shows that a large population size is not a necessary condition for complex behavior and technology.

In a related article, the author states that "Neandertals used artificial adhesives to haft, or better handle, stone tools across their entire geographic range and since at least 200,000 years ago."   That is almost 130,000 years prior to H. Sapiens' final mental evolutionary change 70,000 years ago, and about 145,000 years before H. Sapiens made their way into the parts of Eurasia where H. Neanderthalis lived.

This is clear evidence that Neandertals possessed the ability for abstract conceptualization.   Abstract conceptualization is the mental capability that makes possible reasoning and thinking, which replaces the instinctual behavior that is otherwise universal among animals.   This discovery also makes clear that abstract conceptualization at some level preceded H. Sapiens.

More than a dozen prominent scientists will be presenting evidence Friday and Saturday casting doubt on the United Nations’ assertion that human activity is causing a global warming crisis.

Several of these scientists co-authored or reviewed portions of Climate Change Reconsidered, a series of comprehensive climate science volumes compiled by the Nongovernmental International Panel on Climate Change (NIPCC).

Among the highlights of the EIKE conference, scientists will discuss the latest science regarding natural climate cycles, sea level, solar variability versus atmospheric carbon dioxide concentrations, shortcomings regarding renewable power, flaws in asserted temperature histories, the benefits of a warmer world, desertification, and ulterior goals of climate activists.

“The scientific evidence and conclusions reported by climate scientists are far different than what the environmental left and their legacy media allies would like the public to believe.”

Measured temperature vs. what NOAA reports - See the fraud.

Historic temperatures do not show a warming trend.
