Vets of the study say that if breeders and the public stop selecting the bulldog’s current characteristic features, the future English bulldog will have a longer face, trimmer head, and no skin folds.

The Selective Breeding of English Bulldogs Has Led to a Lot of Health Problems

Their deep facial folds, pronounced underbite and other distinctive features lead to issues

Scientists are turning scientific date, like DNA sequences, into sound.

Why Scientists Are Turning Molecules Into Music

Converting DNA sequences and particle vibrations into notes allows researchers to recognize unseen patterns and create songs for outreach

Researchers surveyed the owners of 18,385 dogs and sequenced the DNA of 2,155 dogs for a new study analyzing dog behavior and breed.   

Dog Breed Doesn't Affect Behavior, According to New Genetic Research

Personality is shaped by a combination of factors, including a pup’s environment

Biotech firm Oxitec is genetically modifying mosquitoes in the hopes of curbing the overall population. The company completed its first open-air release of the bugs in Florida.

First U.S. Open-Air Test of Genetically Modified Mosquitoes Deemed a Success

Biotech firm Oxitec engineered the bugs in an effort to curb their numbers and help stop the spread of disease

Filling in genome gaps could help scientists better the genetic basis for certain diseases and lead to new medical discoveries.

Scientists Have Finally Sequenced a 'Gapless' Human Genome

Scientists have deciphered the missing eight percent of our genetic blueprint, setting the stage for new discoveries in human evolution and disease

After analyzing the DNA of 50 domestic cats, researchers identified regions along the two genes that code for Fel d 1 that the team could cut and edit with CRISPR.

Researchers Are Closer to Creating Hypoallergenic Cats Using CRISPR Technology

The allergen-causing protein Fel d 1 was removed from feline cells using the gene-editing tool

Aedes aegypti can carry several diseases, including yellow fever, dengue and Zika virus. 

Why a U.S. Company Plans to Release 2.4 Billion Genetically Modified Mosquitoes

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.

Mice Birthed From Unfertilized Eggs for the First Time

The lab rodent, which only had genes from its mother, grew to adulthood and successfully reproduced, which was thought to be impossible in mammals

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.
