It’s getting too easy to create dangerous viruses. The upcoming national biodefense strategy should ensure that scientific journals don’t help terrorists learn how.

The news that researchers have recreated an extinct cousin to the smallpox virus using only commercially available technology and items purchased over the Internet renews concerns that bioterrorists could do the same if detailed information about the methods were published. Here’s the problem: scientific journals are geared toward publication, often without sufficient understanding of the public-security risks. We need a better system to ensure that information that could help bad actors stays unpublished.

It took David Evans’ team of scientists at the University of Alberta in Edmonton, Canada, about six months and $100,000 to recreate the horsepox virus, a close relative of the smallpox virus that killed perhaps 300 million people in the 20th century before it was eradicated in 1980. In a summary of the research, the World Health Advisory Committee on Variola Virus Research wrote that “recreation of such viral genomes did not require exceptional biochemical knowledge or skills, significant funds, or significant time.”

You never hear much about cryogenics outside of the US.


Bereaved partner believes science will one day find a cure for the cancer that took his wife, and return her to him.

In the study, 22-month-old rats — who were considered old — received stem cells from four-month-old rats.

Across the board, all of them experienced improved heart function, improved their exercise capacity by an average of 20 percent, and regrew hair faster than rats that didn’t receive the cells.

They also demonstrated longer heart cell telomeres.


Until now, scientists have tested the method to repair damage. But the Cedars-Sinai team in LA — who did the world’s first cardiac stem cell infusion in 2009 — have shown it can also reverse aging.

Let’s keep up the momentum and continue to show the world what power the crowd can have in standing up to age-related disease. # LifespanIO # CrowdfundTheCure.

What I wonder here is if you could do this with uninjured cells, remaking the whole body with new cells.


The new technique, called tissue nanotransfection, is based on a tiny device that sits on the surface of the skin of a living body. An intense, focused electric field is then applied across the device, allowing it to deliver genes to the skin cells beneath it – turning them into different types of cells.

Coming from a fusion of the words ‘protein’ (a molecule that a cell uses as a machine or scaffolding) and ‘stasis’ (meaning to keep the same), the term ‘proteostasis’ can essentially be simplified into “Each function reliant on proteins is running as it should. There are enough proteins to serve a function, and the concentrations of proteins are being maintained at healthy levels.”

Proteostasis is the process that cells perform in order to have all their proteins functioning properly; this, in turn, allows cells to work properly. Since cells are the building blocks of our bodies, when they work properly, we are healthy.

When proteostasis is not maintained, cells become dysfunctional and can die; this failure can lead to aging, cancer, neurodegenerative diseases, inflammation, developmental defects, and other problems. The loss of proteostasis is thought to be a primary reason we age, and we discuss how this happens in more detail here.
