Cancer patients welcome breakthrough ‘living drug’ that reprograms immune systems to fight disease
Posted by Quinn Sena in categories: biotech/medical, genetics, health
In a groundbreaking treatment, cancer patients’ immune systems are being genetically reprogrammed to fight their terminal cancer for them, with promising results.
In the UK, a number of National Health Service (NHS) patients with lymphoma at King’s College Hospital have been given CAR-T, a “living drug” that is unique to each patient as it contains some of their own cells.

Japanese sign up for DNA matchmaking as country faces demographic crisis
Posted by Genevieve Klien in categories: biotech/medical, genetics
The scene resembles a typical blind speed-dating event: 13 women and 13 men, seated on either side of a bamboo screen in an upmarket Tokyo restaurant, are chatting in pairs on a strictly timed three-minute rotation.
But the doctor hovering on the fringes and the scientific documents held in the participant’s hands, however, offer a hint that this is no ordinary dating event: for everyone attending has undergone a DNA test in a bid to find their best romantic match.
Welcome to the world of DNA matchmaking. Forget hobbies, professions, ages or nose sizes: one critical new criteria for finding the perfect partner was recently added to Japan’s fast-paced dating world, with the launch of a new service that promises to find love based on genetic compatibility.

Automatic Quantum Computer Programming: A Genetic Programming Approach
Posted by Quinn Sena in categories: computing, genetics, quantum physics
Provides an introduction to quantum computing for non-physicists, as well as an introduction to genetic programming for non-computer-scientists. The book explores several ways in which genetic programming can support automatic quantum computer programming and presents detailed descriptions of specific techniques, along with several examples of their human-competitive performance on specific problems. Source code for the author’s QGAME quantum computer simulator is included as an appendix, and pointers to additional online resources furnish the reader with an array of tools for automatic quantum computer programming.

Gensight Biologics Releases Data, CFO Responds to LEAF Inquiry
Posted by Steve Hill in categories: biotech/medical, genetics, life extension
Gensight Biologics, a company researching – among other things – the movement of mitochondrial genetic information to the nucleus to treat hereditary genetic diseases (a strategy that could also have an impact on aging according to the SENS Research Foundation), has recently released data for its latest trial of GS010, a therapy against the blindness-causing genetic disease LHON.

Neanderthal and unknown human ancestor DNA found in the “dark heart” of chromosomes
Posted by Genevieve Klien in categories: biotech/medical, genetics
Genes get shuffled and re-dealt with every new generation, meaning many are relatively recent. But while exploring the “dark heart” of the human genome, geneticists have now found some of the most ancient pieces of DNA, inherited from Neanderthals and an as-yet-unknown human relative, which may be affecting our sense of smell to this day.

How common gut bacteria trigger a lethal autoimmune disease
Posted by Paul Battista in categories: biotech/medical, genetics
What causes the immune system, designed to protect us, to turn on the body and attack healthy cells? Common bacteria that reside in the human gut may be partly to blame, say Yale researchers, who studied the origins of a serious autoimmune disease that frequently affects young women.
For their study, the research team focused on cells from patients with antiphospholipid syndrome, an immune system disorder that raises the risk of blood clots. This chronic condition can lead to lung clots, strokes, heart attacks, and in pregnant women, miscarriages or still births.
Using patient immune cells and antibodies, as well as animal models of the disease, the investigators did several experiments to explore the phenomenon. They found that a common gut bacterium, Roseburia intestinalis, can trigger the disease in individuals who have a genetic predisposition. In those patients, the immune system’s defender T and B cells react to a blood protein involved in clotting, and also to the bacteria, in certain amino acids found in the bacteria. Over time, this ongoing “cross-reactive” response leads to tissue damage and chronic disease.
