Innovative New Nanotechnology Will Enable “Healthy” Electric Current Production Inside the Human Body

Posted by in categories: bioengineering, biotech/medical, nanotechnology

The innovative material that creates green energy through mechanical force.

A new nanotechnology development by an international research team led by Tel Aviv University researchers will make it possible to generate electric currents and voltage within the human body through the activation of various organs (mechanical force). The researchers explain that the development involves a new and very strong biological material, similar to collagen, which is non-toxic and causes no harm to the body’s tissues. The researchers believe that this new nanotechnology has many potential applications in medicine, including harvesting clean energy to operate devices implanted in the body (such as pacemakers) through the body’s natural movements, eliminating the need for batteries.

The study was led by Prof. Ehud Gazit of the Shmunis School of Biomedicine and Cancer Research at the Wise Faculty of Life Sciences, the Department of Materials Science and Engineering at the Fleischman Faculty of Engineering, and the Center for Nanoscience and Nanotechnology, along with his lab team, Dr. Santu Bera and Dr. Wei Ji.

Scientists Discover That Mating Can Cause Epigenetic Changes That Last for 300 Generations

Posted by in categories: biotech/medical, genetics

University of Maryland scientists discover that match matters: The right combination of parents in nematode worms can turn a gene off indefinitely.

Evidence suggests that what happens in one generation — diet, toxin exposure, trauma, fear — can have lasting effects on future generations. Scientists believe these effects result from epigenetic changes that occur in response to the environment and turn genes on or off without altering the genome or DNA sequence.

But how these changes are passed down through generations has not been understood, in part, because scientists have not had a simple way to study the phenomenon. A new study by researchers at the University of Maryland provides a potential tool for unraveling the mystery of how experiences can cause inheritable changes to an animal’s biology. By mating nematode worms, they produced permanent epigenetic changes that lasted for more than 300 generations. The research was published on July 9, 2021, in the journal Nature Communications.

Cell Structure Previously Associated With Disease Actually Improves Brain Function

Posted by in categories: biotech/medical, neuroscience

Summary: Axonal swelling in the Purkinje cells of mice had no detrimental impact on firing rate or the speed at which axons transmit signals. At peak firing rate, axons with swellings were less likely to fail than those without.

Source: McGill University.

Researchers at McGill University have shown that a brain cell structure previously thought to be pathological in fact enhances cells’ ability to transmit information and correlates with better learning on certain tasks.

GSK and Vir, navigating early antibody pitfalls, tout delta variant-busting data for latecomer sotrovimab

Posted by in categories: biotech/medical, health

To develop its drug, Vir “deliberately isolated an antibody that binds to a part of the virus that is very difficult for the virus to mutate,” he said. That piece of the virus is “conserved, not only in all the variants, but in SARS-1… and in a whole family of coronaviruses.”

Vir knew the variant onslaught was coming, said the company’s executive vice president of research and chief scientific officer, Herbert “Skip” Virgin, M.D., Ph.D. So far, added Scangos, its premise of targeting a conserved site to maintain efficacy against mutations “seems to be holding true.”

Sotrovimab “appears to retain activity against variants of concern” like alpha, beta, gamma, epsilon and iota, the National Institutes of Health noted in recently updated COVID-19 treatment guidelines. Last week, GSK and Vir provided data suggesting that delta also belongs to that list. Updated lab experiment data posted on the preprint repository bioRxiv showed sotrovimab’s activity against 14 variants including the troubling delta variant—which first surfaced in India and appears to spread more rapidly than the already-speedy alpha—was very similar to that against the original SARS-CoV-2 virus.

Rise of the cyborgs: Inside the technology transcending humanity’s biological limits

Posted by in categories: biotech/medical, cyborgs, neuroscience

Humans are integrating with technology. Not in the future – now. With the emergence of custom prosthetics that make us stronger and faster, neural implants that change how our brains work, and new senses and abilities that you’ve never dreamed of having, it’s time to start imagining what a better version of you might look like.


From reality-enhancing implants to brain-controlled exoskeletons, breakthroughs in bio-tech have fuelled a new fusion of machinery and organic matter.

World Economic Forum Founder Klaus Schwab opens Cyber Polygon 2021 with a warning: “A lack of cybersecurity has become a clear and immediate danger to our society worldwide.”

Giving the welcoming remarks at Cyber Polygon for the second year in a row, Schwab spoke at length about the World Economic Forum’s (WEF) desire to tackle cybersecurity by bringing together a closer merger of corporations, small businesses, and governments.

Researchers discover new genetic driver of autism and other developmental disorders

Posted by in categories: biotech/medical, genetics, neuroscience

Using CRISPR-Cas9, the researchers subsequently removed the one copy of the Ndn gene from the 15q dup mouse model to generate mice with a normalized genomic copy number for this gene (15q dupΔNdn mouse). Using this model, they demonstrated that the abnormalities observed in 15q dup mice (abnormal spine turnover rate and decreased inhibitory synaptic input) could be ameliorated.


A research group including Kobe University’s Professor TAKUMI Toru (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) and Assistant Professor TAMADA Kota, both of the Physiology Division in the Graduate School of Medicine, has revealed a causal gene (Necdin, NDN) in autism model mice that have the chromosomal abnormality called copy number variation.

The researchers hope to illuminate the NDN gene’s molecular mechanism in order to contribute towards the creation of new treatment strategies for developmental disorders including autism.
