The insects, created by biotech firm Oxitec, will be non-biting males engineered to only produce viable male offspring, per the company

Dried cochineal insects — shown here in the center of the photo — can be processed to create several natural dyes such as carmine and cochineal extract. These products get their red hue from carminic acid, a chemical found within the insect.

Scientists Are Making Cochineal, a Red Dye From Bugs, in the Lab

Used to color foods and cosmetics, carminic acid is traditionally 'farmed' from an insect. But researchers are moving to engineer it in microbes

Using human genomes, researchers have developed a massive family tree identifying nearly 27 million ancestors dating back more than 100,000 years ago.

Black-legged ticks, also called deer ticks, carry a variety of diseases that can be passed to humans.

Scientists Edit Tick Genes for the First Time

Altering tick genomes could bring scientists closer to managing ticks and tick-borne illnesses like Lyme disease

Fetal alcohol spectrum disorders could affect between 1 and 5 percent of children in the United States.

New Tools May Help Diagnose Fetal Alcohol Spectrum Disorders

If conditions stemming from exposure to alcohol in-utero can be better identified, then scientists can more effectively research treatments

Researchers have located a genetic mutation associated with smaller dogs.
