The nose is the probable starting point for COVID-19 infections. Richard Boucher and Ralph Baric at the University of North Carolina at Chapel Hill and their colleagues tracked the ease with which the new coronavirus infects various cell types in the respiratory tract. The researchers found a gradient of infectivity that decreases from the upper to the lower respiratory tract: the most easily infected cells are in the nasal cavity, and the least easily infected deep in the lungs.

More than 100 people in Melbourne and Brisbane have signed up to be involved in the first human trials of a vaccine for COVID-19. Clinical research organisation Nucleus Network will be in charge of the early stages of testing the vaccine NVX-CoV2373, before the trial expands to Brisbane within a week.

A unique challenge is emerging in the search for a COVID-19 vaccine: how to balance intellectual property rights with serving the public good. Unfortunately, very few pharmaceutical and biotechnology corporations are participating in the pledge.

The researchers found that their machine learning algorithm was able to detect, segment, quantify and differentiate between types of brain lesions using images of CT scans.

And it's not..No magic bullets either.

We’ve seen AI outperform doctors in spotting breast cancer, lung cancer and skin cancer. Now, researchers from Intel and the University of Pennsylvania are turning their attention to brain tumors. Using Intel’s AI hardware and software, Penn Medicine will lead 29 international healthcare and research institutions in creating an AI model trained on the largest brain tumor dataset ever -- and will do so without sharing sensitive patient data.

Institut Pasteur Korea announced on May 14 that nafamostat, an acute pancreatitis treatment and a blood anticoagulant component, has antiviral effects against the new coronavirus.Institut Pasteur Korea has been conducting drug recreation research since February to discover candidates for COVID-19 tr

Pre–COVID-19, my Instagram feed was a steady stream of my friends, my friends’ kids, and my friends’ meals, with ads for startup kitchen gear and drop-shipped “designer” goods mixed in between. Now, in the middle of the coronavirus pandemic, sponsored posts for a new field of brass and copper “touch tools” are intermingled among those for masks and hand sanitizer. Coming from a range of brands (including some you may have heard of before, like the Peel Touch Tool or the Keysmart CleanKey, and plenty you likely haven’t)...

Aspirin is associated with a reduction in the risk of developing several cancers of the digestive tract, including some that are almost invariably fatal, such as pancreatic and liver cancers. The largest and most comprehensive analysis to date of the link between aspirin and digestive tract cancers found reductions in the risk of these cancers of between 22% and 38%.

Without much of a health budget, Senegal is being championed for controlling the novel coronavirus. From early-detection mobile kits to 3D-printed ventilators, the West African nation is demonstrating a possible model in curbing COVID-19, relying on their experience of managing the Ebola outbreak. In this episode, The Take is joined by Nicolas Haque, Al Jazeera journalist in Dakar, Senegal; Anta James, a regional representative for Catholic Relief Services; Dan Honig, assistant professor at Johns Hopkins University; and Shannon Underwood, an immigration lawyer in Dakar, Senegal.

Famotidine, the active ingredient in Pepcid AC and other heartburn medicines, is being studied as a coronavirus treatment. There’s no word yet that it could be useful at all, but that isn’t stopping people from stocking up.

Blockchain in healthcare was meant to be. With such a large amount of sensitive data to store, the medical field can’t go without the most reliable method of recording, storing and sharing information.

As the drive towards a vaccine against the new coronavirus accelerates, there’s some good news: People with COVID-19 have robust immune responses against the virus, scientists say. The researchers based their conclusions after testing immune T-cell counts in 20 patients who recovered from the infection.

The gene-editing tool CRISPR has been used for the first time inside the body of an adult patient, in an attempt to cure a form of blindness. The treatment: According to the Associated Press, doctors dripped just a few drops of a gene-editing mixture beneath the retina of a patient in Oregon who suffers from Leber congenital amaurosis, a rare inherited disease that leads to progressive vision loss.

Thousands of retired healthcare workers have signed up to help fight coronavirus, but Health Secretary Matt Hancock has stressed that many more are needed. In just 48 hours, 4,000 nurses and 500 doctors answered the call to return to work, Mr Hancock said.

A five-minute, point-of-care coronavirus test could be coming to urgent care clinics next week, and experts say it could be "game-changing." The U.S. Food and Drug Administration issued Emergency Use Authorization to Illinois-based medical device maker Abbott Labs on Friday for a coronavirus test that delivers positive results in as little as five minutes and negative results in 13 minutes, the company said.

This is a profound discussion,do watch.

There is currently no vaccine or specific treatment for COVID-19.

Initial peer-reviewed tests of a potential COVID-19 vaccine shows that it produces antibodies in sufficient amounts to combat the virus.

Yet another insightful interview with the vaccine master.
