Advances in agriculture are being powered by CRISPR to boost carbon capture

CRISPR technology has improved crop resistance to pests and diseases

The gene editing tool is a modern version of the genetic modification that has been done on crops for centuries to create plants with preferred traits. Other applications of CRISPR include creating plants with higher yields and better resistance to climate challenges, as well as foods with improved shelf life and nutrition.

Genetic engineering has accelerated millennia of altering various crops' genes

Although farmers have long cross-bred crops to obtain plants with specific colors, sizes, and other characteristics, these processes took significant time. Today, genetic modification in agriculture involves scientists altering an organism's DNA for various purposes, including enhancing pathogen resistance, removing allergens, and delaying spoilage.

A deeper (nontechnical) dive into how CRISPR works

Extra crispy? No, it's CRISPR, but this gene-editing technology is "extra" in the sense of being momentous and destined to change everything. Through CRISPR, scientist exploit a quirk in bacteria immune systems, allowing them to potentially, and quickly, control genes, remove undesirable traits, and add preferred ones. The possibilities and applications are endless.

CRISPR turns 10 years old

When Dr. Jennifer Doudna and colleagues released a paper in 2012 demonstrating the ability to harness the cell's natural immunity machinery to edit DNA, it received little fanfare. A decade later, the gene editing technology has led to innovations in medicine, evolution, and agriculture—and raised profound ethical questions about altering human DNA.

Learn how environmental conditions are optimized to increase bioremediation efficacy

Through biostimulation, Indigenous microbes are provided with moisture, nutrients, or oxygen to prevent their death and ensure optimal progression of their biochemical reactions. Bioaugmentation can introduce new microbial cultures to target specific compounds not natively found in the environment, while landfarming can spread or aerate contaminated soil to improve access to contaminants.

Agricultural intensification has accelerated declines in pollinator populations

The practice of using farmland more frequently to increase its yield increases the number of residual pesticides and decreases botanical biodiversity. These processes tend to decrease carrying capacity for pollinators by eliminating food sources and nesting habitats.

Despite privacy risks, scientists are using DNA in the air to assess ecosystem health

While DNA in soil and water samples has long been used for such analyses, airborne DNA is being incorporated into such efforts to monitor individual species abundance, detect invasive species, measure biodiversity, and determine the success of conservation actions. Future work may include detecting attacks from biological weapons.

The ancient crops we've forgotten how to grow

Roughly half of all world calories today stem from maize, wheat, and rice. But for most of history, plants were domesticated in highly local places. This video dives into the scientists learning about crops no longer highly in use that once fueled entire civilizations in North America. Some forgotten crops include pitseed goosefoot, maygrass, and sumpweed.

The promise and peril of AI in agriculture

Robots. Drones. Artificial Intelligence. All three are touted as potential saviors for farmers, and are already being deployed on large farms, where they assist with such tasks as managing crops, milking cows, and helping farmers make decisions about their land.
