Engineers tap DNA to create ‘lifelike’ machines

Posted by in categories: biotech/medical, genetics

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.

A Moss Can Naturally Clean Harmful Arsenic From Water

Posted by in categories: biotech/medical, food, sustainability

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.

This moss-covered wall is as air-purifying as 275 urban trees

Posted by in categories: environmental, health, space, sustainability, transportation

From smog-sucking bikes to electric taxis and paint made of car exhaust, designers and architects are stepping up to address air pollution—the world’s single largest health risk. But a new air filter making the rounds in Oslo, Paris, Brussels, and Hong Kong shows that nature may be our best ally in this battle.

Essentially a moss-covered wall, each CityTree removes CO2, nitrogen oxides, and particulate matter from the air while also producing oxygen. A single tree is able to absorb 250 grams of particulate matter a day and remove 240 metric tons of CO2 each year—a level roughly on par with the air purification impact of 275 urban trees. Thirteen feet tall, with a metal frame, the CityTrees are easily installed in a public space, and they even have built-in seating at their base.

Zapping Elderly People’s Brains Supercharges Their Working Memory

Posted by in category: neuroscience

Stimulating the brains of elderly people with electrical currents allowed them to perform just as well on a memory test as people in their 20s — a sign that researchers may have found a noninvasive way to turn back the hands of time when it comes to human memory.

“It’s opening up a whole new avenue of potential research and treatment options,” researcher Rob Reinhart said in a press release regarding the study, “and we’re super excited about it.”

Scientists Say New Quantum Material Could “‘Download’ Your Brain”

Posted by in categories: computing, health, neuroscience, quantum physics

Scientists say they’ve developed a new “quantum material” that could one day transfer information directly from human brains to a computer.

The research is in early stages, but it invokes ideas like uploading brains to the cloud or hooking people up to a computer to track deep health metrics — concepts that until now existed solely in science fiction.

An Interview with Drs. Kelsey Moody & Huda Suliman

Posted by in categories: biotech/medical, life extension

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.
