Nanobots can now enter brain cells to spy on what they’re doing

Posted by in categories: biotech/medical, genetics, nanotechnology, robotics/AI

The ability to cure all disease slowly comes in view. ANI into Agi into ASI needs to be primary focus. Followed by genetics research, and lastly an extreme focus on Medical Nanobots. ASI will of cured most diseases by 2035–2040.


Fleets of advanced versions may one day be able to detect disease and then go about surgically treating it — without ever opening the skull.

Why are male kidneys more vulnerable to disease than female kidneys? Mouse study points to testosterone

Posted by in categories: biotech/medical, genetics, life extension, sex

Female kidneys are known to be more resilient to disease and injury, but males need not despair. A new USC Stem Cell-led study published in Developmental Cell describes not only how sex hormones drive differences in male and female mouse kidneys, but also how lowering testosterone can “feminize” this organ and improve its resilience.

“By exploring how differences emerge in male and female kidneys during development, we can better understand how to address sex-related health disparities for patients with diseases,” said Professor Andy McMahon, the study’s corresponding author, and the director of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at the Keck School of Medicine of USC.

First authors Lingyun “Ivy” Xiong and Jing Liu from the McMahon Lab and their collaborators identified more than 1,000 genes with different levels of activity in male and female mouse kidneys, in a study supported by the National Institutes of Health. The differences were most evident in the section of the kidney’s filtering unit known as the proximal tubule, responsible for reabsorbing most of the nutrients such as glucose and amino acids back into the blood stream.

3D-printed ‘living material’ could clean up contaminated water

Posted by in categories: genetics, sustainability

Researchers at the University of California San Diego have developed a new type of material that could offer a sustainable and eco-friendly solution to clean pollutants from water.

Dubbed an “engineered living material,” it is a 3D-printed structure made of a seaweed-based polymer combined with bacteria that have been genetically engineered to produce an enzyme that transforms various organic pollutants into benign molecules. The bacteria were also engineered to self-destruct in the presence of a molecule called theophylline, which is often found in tea and chocolate. This offers a way to eliminate them after they have done their job.

Scientists Discover ‘Pure Math’ Is Written Into Evolutionary Genetics

Posted by in categories: evolution, genetics, mathematics

Mathematicians delight in the beauty of math that so many of us don’t see. But nature is a wonderful realm in which to observe beauty born out of mathematical relationships.

The natural world provides seemingly endless patterns underpinned by numbers – if we can recognize them.

Luckily for us, a motley team of researchers has just uncovered another striking connection between math and nature; between one of the purest forms of mathematics, number theory, and the mechanisms governing the evolution of life on molecular scales, genetics.

Curing aging should be a moral imperative for all of humanity

Posted by in categories: biotech/medical, cryonics, ethics, genetics, life extension, robotics/AI

The Death of Death is an international bestseller by José Cordeiro and David Wood that claims that “death will be optional by 2045” – or even earlier, if more public and private funds are invested in rejuvenation technologies.

Longevity. Technology: Already available in more than 10 languages, the book provides insight into recent exponential advances in AI, tissue regeneration, stem cell treatment, organ printing, cryopreservation and genetic therapies that, say the authors, offer a realistic chance to solve the problem of the aging of the human body for the first time in human history. In fact, the book’s subtitle is The Scientific Possibility of Physical Immortality and its Moral Defense.

Given that until relatively recently, just mentioning the concept of ‘biological immortality’ was enough to raise eyebrows and with most of the opinion that it should be filed away under ‘science fiction’ or ‘charlatanism’. However, longevity science is advancing at an incredible pace and today there are people who no longer wonder if immortality is possible, but when it will be a reality. We sat down with José Luis Corderio PhD to find out more.

Few People with Cancer Undergo Germline Testing

Posted by in categories: biotech/medical, genetics

Like biomarker tests, germline testing can help doctors determine the best treatments for patients, but such testing may also help identify people whose family members should be offered testing for potential cancer-causing gene changes.

Guidelines recommend that germline testing be offered to all people with male breast cancer, ovarian cancer, pancreatic cancer, and metastatic prostate cancer. For other cancers with lower likelihood of harmful inherited mutations, recommendations for germline testing vary.

But new findings from a study that is examining the extent of testing for germline mutations among people diagnosed with cancer in California and Georgia between 2013 and 2019 found that germline testing rates are still low. Among the more than 1.3 million people in the study, only about 93,000, or 6.8%, underwent germline genetic testing through March 31, 2021, according to findings published July 3 in JAMA.
