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.

The fruity with a hint of double helix assertion is not backed by strong science
The controversial requirement would require 3.5 million people to submit samples to a new government database
Five intriguing discoveries and recent news items

A federal task force should look seriously at investing in genomic methods that allow the simultaneous study of multiple genes
Editor's Note: "Along the Tiger's Trail" is a series about the efforts to monitor tigers and their prey in the Malenad landscape in southwestern India that harbors one of the world's largest population of wild tigers.
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.
As many mysteries as the octopus holds—its comprehensive camouflage, smart suckers, agile brain—its genome is surely holding many more (including how it can regenerate its arms—suckers, nerves and all).
The organisms that cause us untold suffering can also be astounding works of art, sculpted by evolution into elegant, deadly packages. Such is the case for the trypanosomes, the protists I discussed last time as the source of Chagas Disease, but which also cause sleeping sickness in Africa.
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.
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.
New work from the University of Cambridge solidifies link between epigenetic effects from in utero diet and health problems across generations
Tony Zador Tony Zador is a professor of biology at the Cold Spring Harbor Laboratory who studies auditory processing, attention and decision-making in rodents.
// 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 [...]
An engineered bacterium is able to copy DNA that contains unnatural genetic code
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.
Elderly men who have lost the Y in blood cells have their lives cut short, compared with men who still have the little chromosome
