How Do More Contagious COVID-19 Viral Strains Emerge?

Health, Uncategorized

COVID-19 vaccines are needed now more than ever. They arrive right on time as UK’s and South Africa’s problematic new strains emerge, B.1.1.7 and 501Y.V2, respectively. The strains have multiple mutations that appear to make the virus more transmissible. Both strains are different but share a mutation – called N501Y – which is in a crucial part of the virus that it uses to infect the body’s cells. The UK strain is now being discovered in many countries around the world.

Many people and also scientists ask themselves:

What happened? Why now?

How does our personality affect our gut microbiome?

Uncategorized

Our personality is formed by our genes, our lifestyle, our life history, and our environment. Now we learn it is perhaps molded by our inside environment, our microbiome, the ecosystem of gut microbes that live inside us and metabolize our food. As reported yesterday in Inverse, Katerina Johnson, a research associate at the University of Oxford, is publishing a study in the March 2020 edition of the Human Microbiome Journal, in which the gut microbiome is investigated with respect to human personality. The study reveals that people with larger social networks tend to have a more diverse microbiome, and as we know, a more diverse microbiome is associated with more optimal health. The study also found, like many other studies before, that anxiety and stress are linked to reduced diversity and an altered microbiome composition.

How to validate microbiome testing services now that uBiome got busted?

Uncategorized

When science discovers new links between our health, the bacteria in our gut, what we eat, our brain functions, and our moods, people pay attention. Microbiome research has uncovered those gut-brain-axis links after the National Institutes of Health launched a five-year, $150 million research effort, which in turn gave rise to several microbiome testing and research startups who received hundreds of millions in financing, among them Finch TherapeuticsKallyopeSecond Genome, which research specific diseases, and startups such as uBiomeViomeThryve, DayTwo selling direct-to-consumer testing kits for disease prevention. There is also a public, not-for-profit project called American Gut, which has the lowest price for sequencing people’s microbiome at $99 but is limited in its results. Microbiome testing, like all types of genome sequencing or genomics tests, sequences the DNA (or RNA) of living organisms, bacteria and other microbes in this case.

One of these companies, uBiome, will no longer be included in that list. uBiome raised $83 million in venture capital, and was worth a whopping $600 million at the start of 2019, making the deep dive they took recently to nothing more than a liquidation valuation even more dramatic. After a series of unfortunate events of their own making, uBiome got busted for bad accounting practices, and most recently, for faulty science. It has now filed for Chapter 7 with plans to shut down. As reported by FierceBiotech, CVS stores turned down stocking their shelves with uBiome’s at-home, Explorer microbiome consumer test, after the shocking news were revealed. Two weeks ago, Business Insider reported that uBiome lost their laboratory certifications, forcing them to stop their clinical tests activities. Perhaps worse than the accounting practices are the news that the Explorer test had been tainted by using a reference sequence database that included samples from minors, infants and at least one animal and that was populated by fecal samples volunteered by employees and participants from an online fundraiser.
