Fight Aging! Newsletter, March 21st 2022
This study was the first to examine how these networks interact with physical activity and fitness to impact how the brain functions. "This paper is exciting because it gives us some evidence that when people whose brain networks aren't functioning optimally engage in physical activity, we see improvement in their executive function and their independence. Maybe just take the stairs on the way to work. Stand up and walk around a little bit more. That's where you get the most bang for your buck, not crazy, high-intensity exercise."

The (sort of, partial) Father mRNA Vaccines Who Now Spreads Vaccine Misinformation (Part 2)
By DAVID WARMFLASH, MD This is part 2 of David Warmlash’s takedown of Robert W. Malone’s appearance (transcript) on the Rogan podcast. Part 1 is here Menstruation and Fertility Much more than the line about reproductive damage in the Wisconsin News clip that we used to open the story, Malone used the Rogan interview to dive more deeply into the topic, starting with:  …there’s a huge number of dysmenorrhea and menometrorrhagia… By that, he meant excessive menstrual cramping and very heavy, often irregular, bleeding, which he followed up with: …they DENY it… Judging by other parts ...

The (sort of, partial) Father mRNA Vaccines Who Now Spreads Vaccine Misinformation (Part 1)
By DAVID WARMFLASH, MD Robert W. Malone, MD MS, is a physician-scientist who will live in infamy, thanks to the Joe Rogan Experience Podcast boosting his visibility this past December regarding his criticism of COVID-19 vaccines, particularly the mRNA vaccines (Moderna and Pfizer-BioNTech). Subsequently, Malone was banned from Twitter, which further boosted his celebrity status. Describing himself as the inventor of mRNA vaccine technology, he has been reaching a growing number of people with a narrative that makes COVID-19 vaccination sound scary. We cannot embed clips from the Rogan interview, which lasted about three...

Reviewing the Mechanisms that Allow Senescent Cells to Resist Apoptosis
A large portion of research into senescent cells in the context of degenerative aging is focused on how these cells fail to destroy themselves. Senescent cells are primed to enter the programmed cell death process of apoptosis, but various mechanisms hold this off. Sabotaging some of those mechanisms is an effective way to clear a sizable fraction of senescent cells in many old tissues, as demonstrated by the initial small molecule senolytic treatments, such as the dasatinib and quercetin combination. As the authors of today's open access paper note, the fact that these apoptosis-inducing senolytics are only partial...

Modified Red Blood Cells for COVID-19 Vaccination
Researchers at McMaster University in Ontario, Canada created engineered red blood cells to act as a new COVID-19 vaccine technology. The cell membranes have been studded with the SARS-CoV-2 spike protein, and in experiments the researchers have conducted in mice the cells can trigger an immune response with minimal side-effects. The team reports that the technique is relatively quick and easy to perform, and it could be useful in developing vaccines against a variety of viruses and future COVID-19 variants. It appears that humans work most effectively under pressure and times of crisis can be a powerful catalyst for in...

Microfluidic Device for Quick and Accurate SARS-CoV-2 Testing
Researchers at the Institute of Photonic Sciences in Barcelona, Spain, have created a microfluidic chip that can detect the SARS-CoV-2 virus in less than 30 minutes, and with a similar level of accuracy as the current gold-standard test, PCR. The technology combines the speed of antigen tests with the accuracy of PCR and may be useful for point-of-care testing. The technique involves combining a few drops of saliva with fluorescent antibodies against the virus. Then, the saliva sample is passed through a microfluidic channel, where a laser illuminates bound fluorescent antibodies and an optical detector rapidly assesses if...
