Turn.bio is based on the scientific breakthrough work at Stanford of Vittorio Sebastiano, Jay Sarkar, and Marco Quarta. They are now leading the team to develop therapies that return mature differentiated cells to a dramatically younger state leaving their differentiated identity unaltered. Congrats!

On the Transhumanist Wishlist by Prof George Church, or the genes we have to change to enhance the human body and mind, a new post.
Here are some selections from the so-called Transhumanist Wishlist, drawing upon the philosophical movement of transhumanism that calls for using technology to enhance human physiology and intellect, leading to a transformation of what it means to be human:
Charlotte Trainer thought she was out of options when she was diagnosed with Stage-4 inoperable Endometrial cancer in November of 2017. After having a full hysterectomy and 25 rounds of radiation, her doctors told her that the cancer had metastasized to her lungs. There was nothing else they could offer her.
Today, she celebrates being cancer free for one full year after being treated at CHIPSA hospital.
More broadly, biologists are wondering how else deep learning — the AI technique used by both approaches — might be applied to the prediction of protein arrangements, which ultimately dictate a protein’s function. These approaches are cheaper and faster than existing lab techniques such as X-ray crystallography, and the knowledge could help researchers to better understand diseases and design drugs. “There’s a lot of excitement about where things might go now,” says John Moult, a biologist at the University of Maryland in College Park and the founder of the biennial competition, called Critical Assessment of protein Structure Prediction (CASP), where teams are challenged to design computer programs that predict protein structures from sequences.
Deep learning makes its mark on protein-structure prediction.
Millions of people who take aspirin to prevent a heart attack may need to rethink the pill-popping, Harvard researchers reported Monday.
A daily low-dose aspirin is recommended for people who have already had a heart attack or stroke and for those diagnosed with heart disease.
But for the otherwise healthy, that advice has been overturned. Guidelines released this year ruled out routine aspirin use for many older adults who don’t already have heart disease — and said it’s only for certain younger people under doctor’s orders.
A few years ago, researchers discovered that abnormalities in microbial communities, or microbiomes, in the intestine appear to contribute to childhood malnutrition. Now comes word that this discovery is being translated into action, with a new study showing that foods formulated to repair the “gut microbiome” may help malnourished kids rebuild their health [1].
In a month-long clinical trial in Bangladesh, 63 children received either regular foods to treat malnutrition or alternative formulations for needed calories and nutrition that also encouraged growth of beneficial microbes in the intestines. The kids who ate the microbiome-friendly diets showed improvements in their microbiome, which helps to extract and metabolize nutrients in our food to help the body grow. They also had significant improvements in key blood proteins associated with bone growth, brain development, immunity, and metabolism; those who ate standard therapeutic food did not experience the same benefit.
Globally, malnutrition affects an estimated 238 million children under the age 5, stunting their normal growth, compromising their health, and limiting their mental development [2]. Malnutrition can arise not only from a shortage of food but from dietary imbalances that don’t satisfy the body’s need for essential nutrients. Far too often, especially in impoverished areas, the condition can turn extremely severe and deadly. And the long term effects on intellectual development can limit the ability of a country’s citizens to lift themselves out of poverty.
Cilantro, also known as coriander, has been traditionally used as a folk medicine for thousands of years, with one of those uses being as an anticonvulsant to prevent the onset of epileptic seizures. New research from University of California, Irvine, has now for the first time homed in on the specific molecular action that explains how this herb can reduce seizures.
Recently, we had the opportunity to interview Professor George Church, a well-known geneticist and rejuvenation expert whom we have previously interviewed. Prof. Church’s company, Rejuvenate Bio, will be launching a clinical trial to test a rejuvenation therapy in dogs this fall.
In your recent paper on enabling large-scale genome editing, you talked about manipulating endogenous transposable elements with the help of dead Cas9 base editors. At Ending Age-Related Diseases, Andrei Gudkov spoke about the super mutagenic phenotype that arises from the expression of LINE1 reverse transcriptase. In this context, he mentioned the possibility of the retrobiome (as he referred to it) being the main driver of all types of cellular damage, which is consequently improperly addressed due to immunosenescence. Do you share his views on the contribution of LINEs and SINEs in aging? If not, why?
Yes. That is one of the reasons why we explored the tech for editing of repeats. We are now extending this to the germline engineering of repeats.
