From Wheelchair To Walking! How Amanda Leverett Davis Beat Cancer at CHIPSA

Posted by in category: biotech/medical

Amanda Leverett Davis was diagnosed with an aggressive bone cancer called chondroblastic osteosarcoma in March of 2017. By the time her doctors discovered it, the disease had metastasized and advanced to stage 3. Amanda was told it was non-curative.

But nearly two years after her initial diagnosis, Amanda is still alive to share her story, and remarkably, she’s cancer free.

Scissors get stuck—another way bacteria use CRISPR/Cas9

Posted by in categories: bioengineering, biotech/medical

In biotech these days, CRISPR/Cas9 is a hot topic, because of its utility as a precise gene editing tool. Before humans repurposed it, CRISPR/Cas9 was a sort of internal immune system bacteria use to defend themselves against phages, or viruses that infect bacteria, by slicing up the phages’ DNA.

Scientists at Emory University School of Medicine and the Max Planck Unit for the Science of Pathogens have found that the “scissors” component of CRISPR/Cas9 sometimes gets stuck.

Cas9, an enzyme that cuts DNA, can also block without doing any cutting. In the pathogenic bacterium Francisella novicida, Cas9 regulates that need to be shut off for the bacteria to cause disease.

Have mice really been cured of HIV using CRISPR gene editing?

Posted by in categories: bioengineering, biotech/medical

Some mice receiving a therapy that includes CRISPR gene editing appear to have been cured of HIV, but safety concerns must be overcome before human trials.

How a healthy microbiome could supercharge the body’s natural cancer-fighting cells

Posted by in categories: biotech/medical, health

The ways in which the communities of bacteria living within our bodies influence our overall well-being are becoming better understood all the time, and with that better understanding comes potential new ways to intervene for better health outcomes. Adding to this is a new discovery by researchers in Melbourne, who have described how a healthy microbiome can boost the activity of killer immune cells that are vital to fighting off infections and cancer.

U.S. Army Making Synthetic Biology a Priority

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

New thermal cloaking, insect proof uniforms are on the horizon, if the U.S. can get out in front of China.

The U.S. Army’s new Futures Command is accelerating research into synthetic biotechnology to help the military develop next-generation living camouflage and other never-before-seen organisms and materials.

Dimitra Stratis-Cullum, who is overseeing the research in synthetic biology for the U.S. Army Research Laboratory’s Combat Capabilities Development Command, detailed the effort on Thursday at the fourth annual Defense One Tech Summit.

The Rejuvenation Market in Singapore

Posted by in categories: biotech/medical, economics, finance, government, life extension

With its growing aging population, Singapore has a looming crisis, but could also be primed to become a major player in the rejuvenation biotechnology industry.


Singapore has one of the fastest-aging populations in the world. Senior citizens 65 years old or older are expected to make up almost half of Singapore’s population by 2050. Unfortunately, this swelling population is spending more time living with sickness, even though they live longer. While average lifespans have been extended, healthspans have not. [1] Singaporeans have an impressive average life expectancy of 84.8 years, but an average Singaporean born in 2017 is predicted to spend the last ten and a half years in sickness, compared to how a Singaporean born in 1999 is likely to spend only nine twilight years in deteriorating health.

This is becoming a massive concern for the Singaporean government because of the financial strain that this is imposing on Singapore’s budget. Having the world’s second-lowest birth rate coupled with a rapidly aging population means that the ratio of working adults to senior citizens is quickly shrinking. In 2007, there were 6.9 working adults for every senior citizen. By 2030, there will be 2.3 working adults per senior citizen.

21CM Cryopreservation Eval Page Foundation

21st Century Medicine (21CM) is a cryobiology research company whose core mission is to develop a cryopreservation protocol sufficiently benign that whole, donated human organs could be vitrified (stored below −130 degrees Celsius without ice formation) and rewarmed when needed for transplantation –an incredibly ambitious goal that has so far eluded medical researchers. 21CM’s scientists are the original pioneers of whole organ vitrification and have been diligently working on the technique for decades. A significant milestone of their progress toward that goal is their demonstration work on rabbit kidneys. Two of their most relevant publications are “Cryopreservation of organs by vitrification: perspectives and recent advances” (Fahy, Wowk, Wu, Phan, Rasch, Chang & Zendejas 2004) and “Physical and biological aspects of renal vitrification” (Fahy, Wowk, Pagotan, Chang, Phan, Thomson & Phan 2009). These papers are a fantastic resource for anyone interested in just how difficult it is to cryopreserve large organs (and by extension whole animals) for long-term storage with the intent on later recovery of biological function. In short, it is incredibly difficult but progress is slowly being made.

The state-of-the-art whole organ vitrification techniques developed by 21CM are the basis of the human cryopreservation protocols used by some cryonics companies (e.g. Alcor). This is made clear in Alcor’s 2004 publication in the New York Academy of Sciences “The Arrest of Biological Time as a Bridge to Engineered Negligible Senescence” (Lemler, Harris, Platt & Huffman 2004).

A genetic “cheat code” that activates dormant DNA

Posted by in categories: biotech/medical, genetics

Circa 2011


Scientists have found a gene that can ‘lock’ and ‘unlock’ certain sections of your genetic code, allowing other genes to be expressed in your body. If you are under enough stress, this gene springs into action.

So you think you have access to all your DNA just by being born? Think again. You have to earn it, people. You have to work to get there. You have to suffer. Epigeneticists have proved this to be so, but they also might have a cheat code.
