The unusually acrobatic sauteur d’Alfort rabbits were first discovered in France in 1935

Jennifer Doudna, a Nobel Prize recipient for her work on the gene-editing tool CRISPR, and the "life sciences revolution" are the dual subjects of Walter Isaacson's latest biography.

How Scientist Jennifer Doudna Is Leading the Next Technological Revolution

A new book from Steve Jobs biographer Walter Isaacson offers an incisive portrait of the gene editing field that is changing modern medicine

C. elegans are roundworms that are about one millimeter long and commonly used in scientific experiments as model organisms.

These Worms Have No Eyes, but They Avoid the Color Blue

When a scientist noticed that blind nematodes avoid bacteria that make blue toxin, he wondered if they took color into account

Elizabeth Ann, the first cloned black-footed ferret and the first cloned endangered species native to North America, pictured here at 50 days old.

Elizabeth Ann Is the First Cloned Black-Footed Ferret

The creature, the first cloned endangered species native to North America, could provide the fragile population with desperately needed genetic diversity

Steppe mammoths evolved shaggy coats over a million years ago, a trait inherited by woolly mammoths.

Oldest DNA Sequenced Yet Comes From Million-Year-Old Mammoths

Genetic material from three ancient molars reveals secrets of about how the Ice Age elephants evolved

An analysis of the genome of the B.1.1.7 variant of the coronavirus overlaid on the CDC's map of different states' genome sequencing rates. Darker-shaded states have processed more genomes (relative to their total case count) than lighter, greener states.

Why the U.S. Is Struggling to Track Coronavirus Variants

A scattered and underfunded effort at genomic sequencing has hindered the country’s ability to detect different forms of the virus

The protein RAC1 can cause some sperm to spin in circles until they die

Mice Sperm Sabotage Other Swimmers With Poison

A study in mice found that poison-spewing sperm make others swim in circles, but carry the antidote for themselves

Zebrafish are classic study animals for understanding genetics and development.

A Single Altered Gene Can Make Fish Fins More Like Limbs

Researchers find a mutation that offers clues to the ancient sea-to-land transition of vertebrates

These five skulls, which range from an approximately 2.5-million-year-old Australopithecus africanus on the left to an approximately 4,800-year-old Homo sapiens on the right, show changes in the size of the braincase, slope of the face and shape of the brow ridges over just less than half of human evolutionary history.

An Evolutionary Timeline of Homo Sapiens

Scientists share the findings that helped them pinpoint key moments in the rise of our species

An Australian lungfish (Neoceratodus forsteri) at the Haus des Meeres in Vienna, Austria.

Australian Lungfish Has Biggest Genome Ever Sequenced

The air-breathing fish dethrones the Mexican axolotl for the title of largest known genome in the animal kingdom

An artist's illustration of two gray wolves (lower left) vying with a pack of dire wolves for a bison carcass near the tar pits in Rancho La Brea roughly 15,000 years ago.

Dire Wolves Weren't Actually Wolves, DNA Analysis Reveals

Ancient DNA extracted from fossils shows the beast split off from Canis lupus and coyotes nearly 6 million years ago

Out of 381 pairs of identical twins involved in the new study, 39 had more than 100 differences in their DNA.

Many Identical Twins Actually Have Slightly Different DNA

In a new study of over 300 pairs of identical twins, only 38 had perfectly identical DNA

If the platypus looks like a mixture of bird and mammal features, it's because it is.

Platypus Genes Are Just as Odd as the Creature Itself

These egg-laying, lactating animals have genes in common with mammals as well as birds

Archaic Age people—like the ones who made these blades—arrived in the Caribbean around 6,000 years ago.

What Ancient DNA Reveals About the First People to Populate the Caribbean

New study suggests a group of migrants almost totally replaced the islands' original population

Nearly 80 percent of the world's vanilla beans are produced by small farmers in Madagascar. The global supply is tiny compared with demand and is often threatened by extreme weather and disease.

Newly Sequenced Vanilla Genome Could Boost Tiny Global Supply

Tweaking the crop’s genes could help increase its yields and make it more resistant to disease and natural disasters

Of the deep-water samples collected by this team, they identified 11 fish families, 11 genera and eight species. This fish, from the genus Leptochilichthys, was discovered at nearly 3,000 feet deep.

Scientists Collect Floating Bits of DNA to Study Deep Sea Creatures

Analyzing seawater samples reveals what critters lurk there—without having to see them

Scientists caught a juvenile female vaquita in October of 2017 and released her after she showed signs of stress.

Vaquita Genome Offers Hope for Species' Survival

A new study suggests the marine mammal can recover naturally if illegal fishing is eliminated

A genetic analysis revealed that by the end of the last ice age—around 11,000 years ago—there were a least five distinct lineages that gave rise to dogs in New Guinea, the Americas, northern Europe, the Near East and Siberia.

How Dogs and Humans Evolved and Migrated in Tandem

Our relationship with pups spans millennia, and new DNA analysis shows just how much people influenced canine evolution

Rotten fish contain a smellable chemical found in bad breath, faeces and blood, but some people identified it as sweets or roses.

If Rotten Fish Smell Like Roses to You, a Genetic Mutation Might Be to Blame

A new study in Iceland found a connection between a person’s ability to sniff stinky fish and a gene called TAAR5
