I have been fascinated with living things since childhood. Growing up in northern California, I spent a lot of time playing outdoors among plants and animals.
// Editor's note: Brain Basics from Scientific American Mind is a series of short video primers on the brain and how we feel, think and act.
According to the New York Times, synthetic biology is creating DNA out of thin air. A recent article about synthetic biology and consumer goods describes DNA synthesis as a process where “DNA is created on computers and inserted into organisms.” Computers are pretty cool and really useful in synthetic biology labs, but it takes a [...]..
Describing a new species for science is not quite as easy as it was in the days of 17th- or 18th-century naturalists. But that just means we have to look a little more closely.
A federal task force should look seriously at investing in genomic methods that allow the simultaneous study of multiple genes
What if you could trace brain circuits as if you were sequencing genes? A scientist at Cold Spring Harbor Laboratory thinks you can.
The controversial requirement would require 3.5 million people to submit samples to a new government database
One of the greatest breakthroughs in twentieth century biology was the finding that RNA can serve as a catalyst and drive some of life’s essential chemical reactions.

Last month forest rangers in India arrested a 21-year-old engineering student and his friend who had been caught carrying a tiger skin that they intended to sell for nearly $25,000.
“Film is a powerful way to tell stories. … The right story, told well, can be engaging, informative, and memorable.” —Sean B. Carroll The Howard Hughes Medical Institute (HHMI) is adding four new films to its award-winning catalog of short science documentaries for the classroom...
Somewhere deep in my grandmother’s veins, a blood clot breaks free. Her blood carries the clot past her heart, to her lungs, where it becomes stuck in a pulmonary artery.
It's a sad fact that as members of a species become rarer they tend to suffer from inbreeding. This lack of genetic diversity can lead to birth defects and other problems, making a species even more endangered as time progresses...
DNA origami—the art of folding DNA—has expanded hugely in the 10 years since its conception. Nature Video finds out how you can fold DNA into robots. This article was reproduced with permission and was first published on March 18, 2016...
Using the CRISPR–Cas9 system, scientists can do much more than gene editing—they can boost gene transcription or use fluorescent proteins to paint and track a chromosome. In this Nature Video animation, several innovative uses for CRISPR are outlined and explained. This video was reproduced with permission and was first published on October 31, 2017...
An engineered bacterium is able to copy DNA that contains unnatural genetic code
