80% Of Americans Support Mandatory Labels On Foods Containing DNA. DNA!

A recent survey conducted by the Oklahoma State University Department of Agricultural Economics found that 80.44% of respondents supported a government policy mandating labels on foods containing DNA. Not GMOs. DNA, the genetic material contained in every living thing known to science and practically every food,… » 1/18/15 11:08am 1/18/15 11:08am

This Viral DNA Infects Cells by Changing From a Solid to a Liquid

Two new studies are showing that viral infections are possible owing to a remarkable biological phase transition. The research shows that viral DNA transforms from a glassy solid to a fluid-like state when the conditions for infection are just right. The new insight could result in new antiviral therapies. » 10/02/14 3:40pm 10/02/14 3:40pm

Inside the Forensic Lab That Fights Crime and Counterfeits With DNA

What you're looking at is me, being blasted by a fog machine. It's not a prop for a rave or a haunted house; it's vapor laced with custom DNA particles that could prove I was at the scene of a crime. And it's just one way a cutting-edge security firm is using life's building blocks to detect counterfeits and bust… » 9/27/14 5:29pm 9/27/14 5:29pm

You Are Alive Today Thanks to the Symbionts in Your Body

Mitochondria float around in the goo of your cells, tirelessly making the molecules that power your body. But these mitochondria used to be independent of your body; they were bacteria, floating free in the world. You are, at a fundamental level, the result of symbiosis — the interdependence of two life forms. » 9/23/14 11:27am 9/23/14 11:27am

Soviet Doctors Cured Infections With Viruses, and Soon Yours Might Too

In the Soviet Union, western antibiotics couldn't make it past the Iron Curtain. So Eastern Bloc doctors figured out how to use viruses to kill infectious bacteria. Now, with antibiotic-resistant bugs vexing doctors, that eerie yet effective method might come our way. In post-antibiotic world, infection cures you! » 6/07/14 4:51pm 6/07/14 4:51pm

New Double Helix Visualization Revises What We Know About DNA

By using an advanced microscopy technique, researchers have collected the most precise measurements to date of DNA's tangled structure. Their results showed significant variations to the well-known double helix — variations that are offering fresh insights into the inner workings of this life-bearing molecule. » 5/16/14 3:20pm 5/16/14 3:20pm

The First Lifeform Capable Of Passing Down A Juiced-Up Version Of DNA

Scientists have engineered the first living microbe that can carry and pass down an expanded genetic code to future generations — one that has six base pairs instead of the usual four. It's a breakthrough that will not only allow us to build powerful new forms of life, it's also changing what we know about evolution. » 5/08/14 8:00am 5/08/14 8:00am
