In a new study, a team of scientists was able to rewrite a bacteria’s genome entirely from scratch

Posted by in categories: bioengineering, biotech/medical

Model of the human genome.

A special nutrient must be fed to these bacteria or else they die off. Unless they find this selfsame nutrient in the environment, which Church says is unlikely, they would not be able to survive. Another fail-safe is a special barrier which has been erected to make it impossible for the bacteria to mate or reproduce, outside of the lab. But other experts wonder how “unbeatable” Church’s fail-safe’s actually are. Carr says that instead of discussing these measures as foolproof, we should be framing it in degrees of risk.

The next step is further testing of the artificial genes that have been made. Afterward, Church and colleagues will take this same genome and produce an entirely new organism with it. Since DNA is the essential blueprint for almost all life on earth, being able to rewrite it could give humans an almost god-like power over it. That capability is perhaps decades away. Even so, combined with gene editing and gene modification, and the idea of a race of super humans is not outside the realm of possibility.

A Refrigerator Backpack Could Help Transport Vaccines And Organs

Posted by in categories: biotech/medical, life extension, transportation

Medical supply transportation is a serious problem in remote regions, where it may take weeks to transport a vaccine where it’s most needed. But a British student has developed a simple device that might help get supplies where they need to go and save millions of lives in the process.

Will Broadway of Loughborough University created the tank as a way to extend the life of fragile medical supplies, like vaccines, samples, and organs.

The device uses a simple ammonia reaction that creates a cooling effect when charged. It can keep vaccines within a stable temperature realm for up to 30 days. While it’s currently designed for vaccines, Broadway next wants to make it transport organs and tissues to people in need.

Biotech startup says it has nearly perfected making wine in a lab

Posted by in categories: biotech/medical, food

Ava Winery’s first public taste test didn’t exactly go well. Two reporters on camera at New Scientist compared the biotech startup’s artificial wine with a glass of the Moscato D’Asti that it was based on. They complained that the fake wine had too little color, too little viscosity, and an unpleasant plastic smell.

But that was May, and this is September, and Ava is already bragging about making huge improvements in its product, to the point where it is all but indistinguishable from fermented grape juice, and looking ahead to how it’s going to change the world.

“What we have done since then is leaps and bounds beyond what they were able to taste back in May,” co-founder Alec Lee says. “Now we’re at the point where about 90% of people fail out blind taste test.”

Aubrey de Grey & Matthew O’Connor AMA! • /r/Futurology

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

The Aubrey de Grey and Matthew O’Connor SENS AMA on reddit Monday 12th 11am PST.


I am Dr. Aubrey De Grey, biologist, gerontologist PhD and author of the book Ending Aging and Chief Science Officer at the SENS Research Foundation. I am here with researcher Dr. Matthew O’Connor from the MitoSENS project who is an expert on “allotopic expression” of mitochondrial genes. His team has been working on engineering mitochondrial genes to be expressed from the nucleus and targeted to the mitochondia as part of the MitoSENS approach to one of the damages of aging.

Each cell in the body is dependent on the efficient generation of cellular energy by mitochondria to stay alive. Critical to this process are genes encoded within the mitochondrial genome. Over time however, mutations in these genes occur as a result of constant exposure to reactive oxygen species produced by oxidative phosphorylation, the mitochondrial energy generation process. Unlike genes within the nucleus, mitochondria lack an efficient system to repair damaged DNA. This leads to accumulated mutations, resulting in mitochondrial defects and an increase in oxidative stress throughout the body. Closely correlated with this is the observation that organisms which age more slowly also consistently display lower rates of mitochondrial free radical damage. Thus, reversing and/or preventing damage to mitochondrial DNA may be a key factor in slowing the aging process.

Measuring forces in the DNA molecule

Posted by in categories: biotech/medical, genetics

DNA, our genetic material, normally has the structure of a twisted rope ladder. Experts call this structure a double helix. Among other things, it is stabilized by stacking forces between base pairs. Scientists at the Technical University of Munich (TUM) have succeeded at measuring these forces for the very first time on the level of single base pairs. This new knowledge could help to construct precise molecular machines out of DNA. The researchers published their findings in the journal Science.

Over 60 years ago, the researchers Crick and Watson identified the structure of deoxyribonucleic acid, which is more commonly known as DNA. They compared the double helix to a rope ladder that had been twisted into a spiral. The rungs of this ladder consisted of guanine/cytosine and thymine/adenine . But what keeps the DNA strands in that spiral structure?

DARPA reveals program to address ‘safety gaps’ in gene editing

Posted by in categories: bioengineering, biotech/medical

Recent plans to use these techniques to obstruct mosquitoes’ disease-carrying abilities have raised concerns from both experts and the public, and some have even argued that the tool can be used to create biological weapons.

Now, the US Defense Advanced Research Projects Agency has revealed a new program that aims to set a ‘safe course’ for this field, with hopes that their toolkit can work both to support bio-innovation and combat bio-threats.
