As a genetic material, DNA is responsible for all known life. But DNA is also a polymer. Tapping into the unique nature of the molecule, Cornell engineers have created simple machines constructed of biomaterials with properties of living things.

Using what they call DASH (DNA-based Assembly and Synthesis of Hierarchical) , Cornell engineers constructed a DNA material with capabilities of , in addition to and organization – three key traits of life.

“We are introducing a brand-new, lifelike material concept powered by its very own artificial metabolism. We are not making something that’s alive, but we are creating materials that are much more lifelike than have ever been seen before,” said Dan Luo, professor of biological and environmental engineering in the College of Agriculture and Life Sciences.


If you happen to be thirsty in the woods, there are a lot of things you can stick in your canteen to help clean up your drinking water. There are chlorine pills and filters (not crystals — never crystals). And now scientists have identified a certain kind of moss that could do it, too.

The moss is called Warnstorfia fluitans. It grows in Swedish wetlands contaminated with the toxic arsenic from nearby mining operations. Researchers found that the moss brought the arsenic levels of water down to drinkable levels surprisingly quickly, according to research published in the journal Environmental Pollution.

In northern Sweden, iron mines have contaminated much of the water with arsenic, a metal that is also toxic to humans. That harmful combination works its way into agricultural products like rice, traveling throughout the food web.

At Undoing Aging 2019, we interviewed some of the best researchers who are involved in discovering therapies for the root causes of aging. Their research aims to ameliorate the damages of aging and may one day lead to a future without the diseases of aging.

We were glad to have the opportunity to conduct a joint interview with Dr. Kelsey Moody and Dr. Huda Suliman. They offered several keen insights on the future of Ichor Therapeutics and the nature of the rejuvenation biotechnology industry.

K: I’m Dr. Kelsey Moody. I’m the Chief Executive Officer of Ichor Therapeutics and its portfolio of companies. Ichor itself is a biopharmaceutical company that does drug discovery in the aging space, and we have a variety of portfolio companies, each of which is designed to target a different type of age-associated damage. Through these companies, we’re developing classes of different drugs to move into the clinic for conventional therapeutic applications as well as, hopefully, more anti-aging targeted therapies as well.

CHAMPAIGN, Ill. — Bacteria in the human body are sharing genes with one another at a higher rate than is typically seen in nature, and some of those genes appear to be traveling — independent of their microbial hosts — from one part of the body to another, researchers report in the journal Scientific Reports.

The findings are the result of a molecular data-mining method initially conceptualized by Kyung Mo Kim, a senior research scientist at the Korea Polar Research Institute. University of Illinois crop sciences and Carl R. Woese Institute for Genomic Biology professor Gustavo Caetano-Anollés developed the approach with his former student Arshan Nasir, of COMSATS University Islamabad, Pakistan, who is currently a Distinguished Fellow at the Los Alamos National Laboratory in New Mexico.

This computationally challenging method allowed them to identify instances of “horizontal gene transfer,” the direct transfer of genes between organisms outside of sexual or asexual reproduction.

Researchers may be closing in on a way to check athletes while they’re alive for signs of a degenerative brain disease that’s been linked to frequent head blows. Experimental scans found higher levels of an abnormal protein tied to the disease in a study of former National Football League players who were having mood and thinking problems.

It’s the first time a major study has tested these scans for detecting chronic traumatic encephalopathy, or CTE, which is only diagnosed now after death, with brain autopsies.

Doctors are searching for a way to tell when players, veterans or others with concussions or other head injuries are at risk for permanent damage. It’s too soon to know if the scans will enable that — so far they only show that these athletes are different as a group; they can’t be used to say a particular player does or does not have CTE.

Transforming the microbial environment in the guts of children diagnosed with autism could significantly ease the severity of their condition’s signature traits, according to newly published research.

A study on the effects of a form of faecal transplant therapy in children on the autism spectrum found participants not only experienced fewer gut problems, but continued to show ongoing improvements in autism symptoms two years after the procedure.

Arizona State University researchers had already discovered a dose of healthy gut microflora caused characteristics associated with autism spectrum disorder (ASD) to ease or vanish for at least a couple of months after treatment ended.
