DNA

The mold growing on batches of Bayley Hazen Blue cheese changed from green to white between 2016 and the present day.

Scientists Watch Fungi Evolve in Real Time, Thanks to a Marriage Proposal in a Cheese Cave

A new study pinpoints a disruption in a gene that made a beloved blue cheese’s rind go from green to white

An egg with a human skin cell nucleus before fertilization

Scientists Made Functional Human Eggs With Skin Cells in ‘Proof of Concept’ for Advancing Fertility

The research could open up avenues for fertility treatments after additional refinement and trials, but it also raises ethical concerns

The epigenetic clock is emerging as a wildlife conservation tool.

This ‘Clock’ Could Warn of Hidden Stresses to Animals, Offering a Long-Sought Signal That a Population Is Nearing Collapse

The epigenetic clock measures biological age and could help scientists assess the health of polar bears, dolphins, baboons and other threatened creatures “while recovery is still possible”

 Maria Branyas Morera on her 117th birthday

Scientists Studied the Genes of a Woman Who Lived 117 Years. Here’s What They Learned

Maria Branyas Morera, formerly the world’s oldest person, allowed researchers to take a detailed look at her biology before she died last year

Stuttering affects roughly 1 percent of the world's population, yet it is not well researched.

What Causes Stuttering? A Large DNA Analysis Study Offers New Clues, Uncovering Links to 48 Genes

Scientists analyzed data from more than one million users of 23andMe and found associations between certain genes and stuttering

Scientists are considering what limits to potentially place on mirror-image cell research.

Scientists Weigh the Risks of ‘Mirror Life,’ Synthetic Molecules With a Reverse Version of Life’s Building Blocks

Though mirror biology might lead to improved drugs and other innovations, scientists have warned against potentially devastating consequences of this research

The researchers studied the genomes of thousands of ant specimens stored in museum collections.

Fiji’s Ants Are Struggling. Scientists Say They’re Part of the Broader ‘Insect Apocalypse’

New research finds that 79 percent of Fiji’s endemic ant species—those that are native to and only found on the archipelago—are in decline

Researchers studied genetic samples from 483 mammoths, including from their tusks, bones, skin and molars (shown here).

Scientists Investigate the Bacteria That Colonized Extinct Mammoths—and Uncover the Oldest Known Microbial DNA From a Host

Some of the microbes might have been benign or helpful, while others could have caused deadly diseases

Golden apple snails and humans have similar eyes with related structures. Understanding how the snails can regrow them could help scientists heal human eyes.

This Snail Can Regrow Its Eyes—and Understanding How May One Day Help Humans With Injuries

Researchers pinpointed a gene related to eye development in golden apple snails, which can regenerate amputated eyes within about a month

An illustration of E. coli. Scientists have been racing to shrink the genetic code of this bacterium.

Scientists Rewrite the Genetic Code of E. Coli, and It’s Drastically Different From Anything Found in Nature

The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64, freeing up space for further edits that might lead to new drugs or virus-resistant microbes

New light microscopy techniques can distinguish objects down to less than ten nanometers. 

These Super-Resolution Microscopes Are Revealing the Inner Lives of Cells

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases

A Late Neolithic skull. For the recent study, scientists extracted DNA from skulls and teeth to look for traces of diseases.

With Ancient DNA, Scientists Have Mapped 37,000 Years of Disease Across Europe and Asia

Zoonoses—diseases that spread from animals to humans—began to gain prevalence some 6,500 years ago with the rise of animal husbandry, a new study suggests

Scientists sequenced ancient proteins in a tooth from a prehistoric rhino relative that had been preserved in Canada's High Arctic for up to 24 million years.

Scientists Recover Ancient Proteins From Animal Teeth Up to 24 Million Years Old, Opening Doors to Learning About the Past

Two new papers analyze fossils found in Canada and Kenya, respectively—vastly different environments for the preservation of genetic material

Greenlandic sled dogs, also known as Qimmit, play while resting.

Greenland Sled Dog DNA Reveals a Story of Human Migration and Ancestry of the Unique Breed

Researchers analyzed ancient and modern genetic samples of the Greenlandic Qimmit breed to shed light on the long relationship between the Inuit and their dogs in the Arctic

For the first time ever, the genome of a knotty sea spider was sequenced in high resolution.

These ‘Weird’ Sea Spiders Don’t Have Abdomens—and Instead Store Organs in Their Legs. With DNA, Scientists Are Learning Why

Researchers sequenced the knotty sea spider’s genome for the first time, revealing a missing gene that many other animals have

A facial reconstruction using a 3D scan of the skull

New Research

Scientists Have Sequenced an Ancient Egyptian Skeleton’s Entire Genome for the Very First Time. Here’s What They Found

Dating back more than 4,500 years, the skeleton belonged to a middle-aged man who may have worked as a potter and likely descended from ancestors in North Africa and Mesopotamia

A catch of Baltic Sea cod in 1987 shows fish that grew more than three feet long, with Finnish fisheries biologist Eero Kalevi Aro.

These Cod Have Been Shrinking Dramatically for Decades. Now, Scientists Say They’ve Solved the Mystery

Eastern Baltic cod grow to much smaller sizes than they did just 30 years ago, because overfishing altered their genes, according to new research

The new study analyzed 131 skeletons dated to between 7100 and 5950 B.C.E.

Ancient DNA Reveals That Men Moved in With Their Brides’ Families in This Neolithic Settlement

A new study suggests that a 9,000-year-old society in Catalhoyuk, a proto-city in southern Anatolia, may have established a “female-centered” social structure

Scientists and artists collaborated to reconstruct the face of a 10,500-year-old woman whose remains were found in the Meuse Valley of Belgium.

See the Face of a 10,500-Year-Old Woman, Reconstructed by Archaeologists and Artists

Using well-preserved ancient DNA, researchers have created a life-like facial reconstruction of a woman who lived in Belgium’s Meuse Valley during the Mesolithic period

These skeletons of two hunter-gatherer individuals excavated at the Checua archaeological site north of Bogotá, Colombia, helped uncover the genetic details of a mysterious population.

Ancient DNA Reveals Mysterious New Group of Humans in Colombia With No Genetic Ties to People Today

The previously undocumented lineage of hunter-gatherers seems to have disappeared around 2,000 years ago
