Researchers develop new method for specializing and purifying human stem cells into interneurons

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

Injury to the spinal cord often leads life changing disability, with decreased or complete loss of sensation and movement below the site of injury. From drugs to transplantation, there are many scientific advances aiming to restore function following spinal cord injury.

One promising approach is the use of stem cell derived neurons to replace those damaged. New research from the Centre for Gene Therapy & Regenerative Medicine and Centre for Neurodevelopment at King’s College London hopes to improve on this approach by providing pure populations of neurons made from stem cells.

The spinal cord is a delicate structure, with neurons carry messages from your brain to the rest of your body to allow movement and sensation. Integral to this system are interneurons, or the cells that relay information between your brain and other neurons. Research has previously shown that transplanting a class of interneurons, ventral spinal interneurons, to treat spinal cord injury in animal models provides promising recovery of sensory and motor function.

Transplanting a Gene Common in Centenarians Could Rewind The Heart’s Age

Posted by in categories: biotech/medical, life extension

Age catches up with us all eventually, but in some people the right genes can make that chase into our twilight years a relatively leisurely one.

A few years ago Italian researchers discovered something special about people who live well into their 90s and beyond: they commonly have a version of a gene called BPIFB4 that protects against cardiovascular damage and keeps the heart in good shape for a longer period of time.

By introducing the mutated gene into older mice, the scientists have now seen how the variant rewinds markers of biological heart aging by the equivalent of more than 10 human years.

A CEO who sold his company for $800 million has helped build 4 $1 billion companies — here’s why he thinks investors should get in early on one of tech’s unsexy, neglected markets

Posted by in categories: biotech/medical, life extension

Bryan Johnson is 45 years old but, according to a new report, his test results show he has the heart of a 37-year-old and the lungs of a young adult.

Johnson is a biotech entrepreneur who hopes to game nature’s course of aging and have the organs and health of an 18-year-old by going through an intense data-driven experimental program he’s called Project Blueprint.

According to a recent Bloomberg profile of the CEO, Johnson could spend up to $2 million on his body this year and there are early glimpses that show he may be on track to unlocking the secret to age reversal.

More people are living to be 100: Here’s why

Posted by in categories: genetics, life extension

Does the secret to reaching extreme old age lie in lifestyle or genetics? Story at a glance America’s population is aging, with more people living to be 100. Reaching extreme old age depends on multiple factors like location, gender, lifestyle and parental age of death.

Will Revitalizing Old Blood Slow Aging?

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

Rejuvenating an older person’s blood may now be within reach, based on recent findings from Passegué’s lab published in Nature Cell Biology(link is external and opens in a new window).

Passegué, with her graduate student Carl Mitchell, found that an anti-inflammatory drug, already approved for use in rheumatoid arthritis, can turn back time in mice and reverse some of the effects of age on the hematopoietic system.

Researcher uses AI to make texts that are thousands of years old readable

Posted by in categories: life extension, robotics/AI

How should we live when we know we must die? This question is posed by the first work of world literature, the Gilgamesh epic. More than 4,000 years ago, Gilgamesh set out on a quest for immortality. Like all Babylonian literature, the saga has survived only in fragments. Nevertheless, scholars have managed to bring two-thirds of the text into readable condition since it was rediscovered in the 19th century.

The Babylonians wrote in cuneiform characters on clay tablets, which have survived in the form of countless fragments. Over centuries, scholars transferred the characters imprinted on the pieces of clay onto paper. Then they would painstakingly compare their transcripts and—in the best case—recognize which fragments belong together and fill in the gaps. The texts were written in the languages Sumerian and Akkadian, which have complicated writing systems. This was a Sisyphean task, one that the experts in the Electronic Babylonian Literature project can scarcely imagine today.

Enrique Jiménez, Professor of Ancient Near Eastern Literatures at LMU’s Institute of Assyriology, and his team have been working on the digitization of all surviving cuneiform tablets since 2018. In that time, the project has processed as many as 22,000 text fragments.
