Researchers discover one of the largest known bacteria-to-animal gene transfers inside a fruit fly

Posted by in categories: biotech/medical, genetics

A fruit fly genome is not a just made up of fruit fly DNA—at least for one fruit fly species. New research from the University of Maryland School of Medicine’s (UMSOM) Institute for Genome Sciences (IGS) shows that one fruit fly species contains whole genomes of a kind of bacteria, making this finding the largest bacteria-to-animal transfer of genetic material ever discovered. The new research also sheds light on how this happens.

The IGS researchers, led by Julie Dunning Hotopp, Ph.D., Professor of Microbiology and Immunology at UMSOM and IGS, used new genetic long-read sequencing technology to show how genes from the bacteria Wolbachia incorporated themselves into the fly genome up to 8,000 years ago.

The researchers say their findings show that unlike Darwin’s finches or Mendel’s peas, isn’t always small, incremental, and predictable.

Nanoscale Rotors Constructed From DNA — Smallest Flow-Driven Motors in the World

Posted by in categories: biotech/medical, nanotechnology

Scientists have constructed the smallest flow-driven motors in the world. Inspired by iconic Dutch windmills and biological motor proteins, they created a self-configuring flow-driven rotor from DNA that converts energy from an electrical or salt gradient into useful mechanical work. The results ope.

Transfusing blood from an old mouse to a younger mouse causes ageing

Posted by in categories: biotech/medical, life extension

View insights.


Transfusing young mice with blood from older rodents quickly triggers ageing, suggesting that cellular ageing isn’t just a case of wear and tear.

There is a longstanding hypothesis that surgically connecting an old mouse with a young rodent causes a transfer of blood that de-ages the older animal. While this benefits the older mouse, the effects on the young donor rodent were less clear.

Bioelectronics will be commonly used by 2025

Posted by in category: biotech/medical

Bioelectronics are a relatively new scientific field that could one day result in a new class of medicines that would not be pills or injections but miniaturised, implantable devices.

GSK believes that these devices could be programmed to read and correct the electrical signals that pass along the nerves of the body, including irregular or altered impulses that can occur in association with a broad range of diseases. The hope is that through these devices, disorders as diverse as inflammatory bowel disease, arthritis, asthma, hypertension and diabetes could be treated.

What Life Will be Like with Bioelectronic Medicine

Posted by in categories: biotech/medical, health

In a first-of-its-kind gathering at the New York Academy of Sciences, researchers from some of the world’s leading universities and institutions convened to discuss at the 13th annual Key Symposium the various applications of bioelectronic medicine, the cutting-edge field that uses technology to treat disease and injury. While still in early stages of development, bioelectronic medicine has already been proven in studies and clinical trials to successfully treat conditions including paralysis and rheumatoid arthritis.

This panel, moderated by Miles O’Brien from PBS’ NewsHour, discusses what life will be like when we can fully modulate the nervous system and the impact that would have on disease, drugs, the healthcare industry, personal freedom, and privacy. The panel includes Polina Anikeeva, PhD, from the Massachusetts Institute of Technology, Chad Bouton from The Feinstein Institute for Medical Research at Northwell Health, Peder S. Olofsson, MD, PhD, from the Karolinska Institutet, and Doug Weber, PhD, from the U.S. Defense Advanced Research Projects Administration.

New DNA repair-kit successfully fixes hereditary disease in patient-derived cells

Posted by in categories: biotech/medical, genetics

Genetic mutations which cause a debilitating hereditary kidney disease affecting children and young adults have been fixed in patient-derived kidney cells using a potentially game-changing DNA repair-kit. The advance, developed by University of Bristol scientists, is published in Nucleic Acids Research.

In this new study, the international team describe how they created a DNA repair vehicle to genetically fix faulty podocin, a common genetic cause of inheritable Steroid Resistant Nephrotic Syndrome (SRNS).

Podocin is a protein normally located on the surface of specialized and essential for . Faulty podocin, however, remains stuck inside the cell and never makes it to the surface, terminally damaging the podocytes. Since the disease cannot be cured with medications, gene therapy which repairs the causing the faulty podocin offers hope for patients.

For more information on Aubrey de Grey, please visit our website www.tedxmuenchen.de.

Dr. Aubrey de Grey is a biomedical gerontologist based Mountain View, California, USA, and is the Chief Science Officer of SENS Research Foundation, a California-based 501©(3) biomedical research charity that performs and funds laboratory research dedicated to combating the aging process. He is also Editor-in-Chief of Rejuvenation Research, the world’s highest-impact peer-reviewed journal focused on intervention in aging. He received his BA in computer science and Ph.D. in biology from the University of Cambridge. His research interests encompass the characterisation of all the accumulating and eventually pathogenic molecular and cellular side-effects of metabolism (“damage”) that constitute mammalian aging and the design of interventions to repair and/or obviate that damage.
