"Borgs" are extrachromosomal elements, meaning that these DNA sequences are found outside the chromosomes that lie within the nucleus of most cells and that contain the majority of an organism’s genetic material. Examples of extrachromosomal elements include plasmids, which can...

Cannabinoids are the next big thing in the pot industry

It’s 2021 and regular THC isn’t going to cut it for the budding weed industry. Neither will CBD. Instead, a host of startups are betting that weed consumers will be clamoring for something that nature alone can’t provide.

In Berkeley, California, the startup Demetrix, is preparing to manufacture “metric tons” of...

CRISPR and the Code Breaker

March 8, 2021

Visionary biochemist Jennifer Doudna shared the Nobel Prize last year for the gene-editing technology known as CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats), which has the potential to cure diseases caused by genetic mutations. Correspondent David Pogue talks with Doudna about the promises and perils of CRISPR; and with Walter Isaacson, author of the new book "The Code Breaker," about why the biotech revolution will dwarf the digital revolution in importance.

Since my colleagues and I first described CRISPR as a genome-engineering tool in 2012, the technique has transformed fundamental research. More than 15,000 papers containing the term have been published, hundreds of different organisms have been edited and this...

Alumna tackles tuberculosis with new portable diagnostic tool

Tuberculosis is caused by Mycobacterium tuberculosis, a bacteria with a cell wall thick enough to block out most drugs. Mireille Kamariza designed a molecule that embeds into that wall and lights up — researchers only need a microscope and a reagent to see it. Photo by Fred Tomlin.

Growing up in Bujumbura, Burundi, Mireille Kamariza (M.S. '15,...

The race to repurpose nature’s protein factories

February 8, 2021

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between standard α-amino acids to make peptides and proteins.

Ribosomes are so good at their job that researchers want to harness them to make other polymers...
