Engineering the Microbiome: CRISPR Leads the Way
Mariella Bodemeier Loayza Careaga, PhD | Mar 15, 2024 | 10+ min read
Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

HIV Hitches a Ride The statistics are grim: More than 34 million people worldwide affected with HIV/AIDS, and 800,000- 900,000 cases in the United States with a steady rate of 40,000 new HIV infections each year. Fueled by such statistics, HIV research continues with scientists at the National Institute of Allergy and Infectious Diseases (NIAID) recently discovering a mechanism providing insight into the pathogenesis of the virus in which HIV may hitch a ride from select cells to target cells.

Genetic Parasites and a Whole Lot More

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c

When Stop Means Go

A survey of trillions of base pairs of microbial DNA reveals a considerable degree of stop codon reassignment.
A Genomic View of Oceanic Life
Leslie Pray | Oct 14, 2001 | 6 min read
Last year, scientists discovered a unique, energy-generating, light-absorbing protein previously unknown to exist in oceanic life. They named the protein proteorhodopsin.1 The bacteria that harbor it are a distinct phylogenetic group known as SAR86. This year, scientists learned that as much as 10 percent of the ocean's surface is occupied by these proteorhodopsin-containing bacteria--as many as 1x105 cells per milliliter of sea water.2 The researchers, led by marine microbiologist Edward DeLo
