Aubrey de Grey — COVID19 — Fighting Infections with Rejuvenation Biotechnology

Posted by in categories: biotech/medical, genetics, life extension

Can Rejuvenation Biotech Help Boost Immune Response to Infectious Diseases? Aging of the immune system makes reduces immune response in elderly — 3 main reasons: cell loss (naive t-cells), accumulation of cells we don’t want (death resistant cells), and changes to internal constitution of the cells.

Early stage research by Janko Nikolich-Žugich indicates that the naive T-cells* produced by the thyamus may not work properly because of something going on with the lymph nodes.

CDC: Asymptomatic children could play important role in coronavirus spread

Posted by in category: biotech/medical

Compared to adults, children with the coronavirus are less likely to be hospitalized or show symptoms like a fever, cough or shortness of breath, new U.S. data from the Centers for Disease Control and Prevention show.

Why it matters: Those with less serious illness or who are asymptomatic likely play a large role in transmitting the disease. Social distancing is thus important for all age groups, the CDC stressed.

By the numbers: Among the 149,082 confirmed U.S. cases of COVID-19 that the CDC tracked as of April 2, 1.7% were patients under the age of 18.

COVID-19 Update 8: Zinc and chloroquine for the treatment of COVID-19?

Posted by in categories: biotech/medical, education, health, media & arts

Anecdotal evidence suggests that the combination of zinc and hydroxychloroquine may be beneficial for the treatment of Covid-19:


We have been asked again and again — “What else can I do, apart from social distancing, hand hygiene, and so on, to protect myself from COVID-19?” There are additional actions that can be taken.

These brain-boosting devices could give us intelligence superpowers

Posted by in categories: biotech/medical, Elon Musk, health, robotics/AI

Circa 2017


The era of merging our minds with technology has begun. Already, we can hack the brain to treat diseases such as Parkinson’s or help paralyzed people move again. But what if you could install a chip in your head that would not only fix any health issues, but could amp up your brainpower — would you remember every word said during a meeting, finish crossword puzzles faster, drive better thanks to enhanced senses, or pick up a new language before your next trip?

That’s the future envisioned by Elon Musk, the Tesla and SpaceX CEO who recently announced Neuralink, a new company dedicated to blending human brains with computers. In Musk’s view, we’ll have to keep pace with ever-smarter artificial intelligence by implanting a “neural lace,” or sci-fi inspired machine interface that will make us smarter.

A new perspective

Posted by in category: biotech/medical

The rapidly spreading COVID-19 epidemic has created an unusual situation: in each population that is infected by the virus, large parts of the population will be infected within a well-defined short time period, with near certainty. A major question is thus: Can the unusual predictability of the infections’ timing be utilized to mitigate the imminent infection’s length, severity, and probability of complications?

We suggest that priming the immune system for attack shortly before it is expected to occur, e.g. via a vaccine that elicits a broad anti-viral immune response, may have this desired effect. Early activation of the immune system would allow it to clear the infection faster and with less complications than otherwise. This would alleviate adverse clinical outcomes at the individual level, and mitigate population-level risk by reducing need for hospitalizations and decreasing the infectious period of individuals, thus slowing the epidemic’s spread and reducing its impact.

Ancient tooth proteins reveal our relation to mysterious human species

Posted by in categories: biotech/medical, evolution

It’s hard to piece together the full history of human evolution from piles of old bones. But now, scientists have made use of a new method to study proteins in dental enamel of an 800,000-year-old human species, helping place it in the family tree.

Although Homo sapiens is the only human species still alive today, the road to get here is paved with extinct relatives. And untangling how they’re all related to each other is a task that scientists continue to wrestle with. The timeline is usually determined through various dating processes, both on the bones themselves and the sediment layers they’re found in. Relationships between species are then determined from this timeline, and by examining the structures and features of the bones to track the progress of evolution.

For the new study, researchers at the University of Copenhagen have used a new tool called palaeoproteomics to get a more precise picture. This involves sequencing proteins from ancient remains, and it works on samples that are far too old to have intact DNA. In this case, the team applied it to the 800,000-year-old teeth of a mysterious, archaic human species called Homo antecessor.

Why do some young people die of coronavirus?

Posted by in category: biotech/medical

Covid-19 hits the old hardest, but young people are dying too. Scientists say it may be down to genes or ‘viral load’.

Real life ‘shrink ray’ can reduce 3D structures

Posted by in categories: biotech/medical, quantum physics

Could used for anything to reduce size just like an ant man suit :3.


Scientists can put all kinds of useful materials in the polymer before they shrink it such as metals, quantum dots and DNA. Pictured is the machine used to shrink objects.

The polyacrylate forms the scaffold over which other materials can be attached.

HIV drug showing signs of successfully treating coronavirus patients

Posted by in category: biotech/medical

A drug used to treat HIV and cancer patients has shown success in treating some of the most severe coronavirus patients and was just cleared by the U.S. Food and Drug Administration to start a phase two clinical trial. Much of the work behind the drug is happening in Washington state.
