Lifeboat Foundation

(https://hscrb.harvard.edu/labs/whited-lab/) is an Assistant Professor of Stem Cell and Regenerative Biology at Harvard University where her lab focuses on limb regeneration in axolotl salamanders and where they develop tools to manipulate gene expression during limb regeneration, and explore signaling events following wound healing that initiate the regenerative process.

Dr. Whited earned a B.A. in Philosophy and a B.S. in Biological Sciences from the University of Missouri, and obtained her Ph.D. in Biology from MIT, where she studied in Dr. Paul Garrity’s laboratory.

David Sinclair shares another side of himself. Compassion for all people. He wants to make sure that longevity technologies are available for all people, not just for the super wealthy and their pets. He also speaks of emerging elderly populations who can live well up until death rather than suffering for so long, and instead start new careers and hobbies.

Researchers have restored vision in animal by resetting some of the thousands of chemical marks that accumulate on DNA as cells age. The work, by Dr David Sinclair Lab, published in Nature Dec 2020, suggests a new approach to reversing age-related decline, by reprogramming some cells to a ‘younger’ state in which they are better able to repair or replace damaged tissue.

By making remarkable breakthroughs in a number of fields, unlocking new approaches to science, and accelerating the pace of science and innovation.

In 2020, Google’s AI team DeepMind announced that its algorithm, AlphaFold, had solved the protein-folding problem. At first, this stunning breakthrough was met with excitement from most, with scientists always ready to test a new tool, and amusement by some. After all, wasn’t this the same company whose algorithm AlphaGo had defeated the world champion in the Chinese strategy game Go, just a few years before? Mastering a game more complex than chess, difficult as that is, felt trivial compared to the protein-folding problem. But AlphaFold proved its scientific mettle by sweeping an annual competition in which teams of biologists guess the structure of proteins based only on their genetic code. The algorithm far outpaced its human rivals, posting scores that predicted the final shape within an angstrom, the width of a single atom. Soon after, AlphaFold passed its first real-world test by correctly predicting the shape of the SARS-CoV-2 ‘spike’ protein, the virus’ conspicuous membrane receptor that is targeted by vaccines.

The success of AlphaFold soon became impossible to ignore, and scientists began trying out the algorithm in their labs. By 2021 Science magazine crowned an open-source version of AlphaFold the “Method of the Year.” Biochemist and Editor-in-Chief H. Holden Thorp of the journal Science wrote in an editorial, “The breakthrough in protein-folding is one of the greatest ever in terms of both the scientific achievement and the enabling of future research.” Today, AlphaFold’s predictions are so accurate that the protein-folding problem is considered solved after more than 70 years of searching. And while the protein-folding problem may be the highest profile achievement of AI in science to date, artificial intelligence is quietly making discoveries in a number of scientific fields.

Cells not replaced, but old cells that are still there are rejuvenated.

Dr David Sinclair explains the mechanism behind how to reprogramm the old cells rejuvenate to be young again. He also clarify the process is based on cell autonomous effect and does not involve or rely on any stem cells in this clip.

Whatever you are doing, whether it is driving a car, going for a jog, or even at your laziest, eating chips and watching TV on the couch, there is an entire suite of molecular machinery inside each of your cells hard at work. That machinery, far too small to see with the naked eye or even with many microscopes, creates energy for the cell, manufactures its proteins, makes copies of its DNA, and much more.

Among those pieces of machinery, and one of the most complex, is something known as the nuclear pore complex (NPC). The NPC, which is made of more than 1,000 individual proteins, is an incredibly discriminating gatekeeper for the cell’s nucleus, the membrane-bound region inside a cell that holds that cell’s genetic material. Anything going in or out of the nucleus has to pass through the NPC on its way.

“When the Human Genome Project began in 1990, it had a projected budget of $3 billion. […] Now, one company claims to have achieved the major milestone of whole genome sequencing for just $100.”

Ultima Genomics, a biotech company based in California, has emerged from stealth mode with a new high-throughput, low-cost sequencing platform that it claims can deliver a $100 genome.

When the Human Genome Project began in 1990, it had a projected budget of $3 billion. Some researchers believed it would take centuries to map all 20,000+ genes and to determine the sequence of chemical base pairs making up DNA, though in the end it took 13 years. Since then, genome sequencing has undergone technology and cost improvements at a rate faster than Moore’s Law (a long-term trend in the computer industry that involves a doubling of performance every two years). What used to require billions of dollars and many years of work is now several orders of magnitude cheaper and possible in a matter of hours.

Not that Thier should be more animals raised for meat.

But beefalo does have its opponents.

“We just don’t think there should be beefalo,” said Martha McFarland, farmland viability coordinator for the advocacy group Practical Farmers of Iowa. She also raises cattle and bison, but said she would never mix the two.

Having multiple conditions that affect the heart are linked to a greater risk of dementia than having high genetic risk, according to a largescale new study.

Led by Oxford University and the University of Exeter, the study is among the largest ever to examine the link between several heart-related conditions and dementia, and one of the few to look at the complex issue of multiple health conditions.

Published in The Lancet Healthy Longevity, the paper looked at data from more than 200,000 people, aged 60 or above, and of European ancestry in UK Biobank. The international research team identified those who had been diagnosed with the cardiometabolic conditions diabetes, stroke, or a heart attack, or any combination of the three, and those who went on to develop dementia.
