Could rats be genetically wired for New York City living?

Rats May Be Genetically Adapted to New York Living

Perhaps it was not just a massive slice that made Pizza Rat a true New Yorker

Ginkgo trees, which produce characteristic fan-shaped leaves, can live for thousands of years.

New Research

A Genetic Elixir of Life Helps Millennia-Old Ginkgo Trees Escape Death

These trees have developed an army of molecular weapons to stay healthy in old age

“Their bone size indicates that they were probably militiamen,” says archaeologist Nicholas Bellantoni. "Their femur bones show that they clearly walked a lot and carried a lot of weight back in their day.”

Cool Finds

Skeletons Unearthed in Connecticut May Belong to Revolutionary War Soldiers

If confirmed, the bones would be the first remains recovered from Revolutionary War soldiers in the Constitution State

An undated composite sketch of Joseph Henry Loveless, whose headless torso was found in a remote Idaho cave 40 years ago

DNA Evidence Identifies Headless Corpse in Cave as 1916 Axe Murderer

Joseph Henry Loveless murdered his wife with an axe more than 100 years ago. Now, his dismembered remains have been identified

Formalin-fixed lung collected in 1912 in Berlin from a 2-year-old girl who died of measles-related pneumonia

Century-Old Lungs May Push Origin of Measles Back 1,500 Years

The viral infection may have made its first hop into humans when large cities arose

Nearly a century ago, archaeologists started to shift the focus of human origins research from Europe to Africa’s ‘cradles of humankind’ like Oldupai (Olduvai) Gorge in Tanzania.

Archaeologists Are Unearthing the Stories of the Past Faster Than Ever Before

Recent research helps reveal the origins of humans, determine what ancient people ate and monitor historical sites from the sky

A 5,700-year-old piece of birch tar, chewed as gum, contains the genome, mouth microbes, and even dietary information about its former chewer.

Human Genome Recovered From 5,700-Year-Old Chewing Gum

The piece of Birch tar, found in Denmark, also contained the mouth microbes of its ancient chewer, as well as remnants of food to reveal what she ate

Unlike classic CRISPR-based editing, which fully cleaves DNA in two, prime editing starts with a cut to only one strand of the double helix.

A New Gene Editing Tool Could Make CRISPR More Precise

Prime editing offers a new way to make changes to DNA while avoiding some of the drawbacks and clunkiness of traditional CRISPR

The skull of the 1.77-million-year-old Stephanorhinus rhino.

1.7-Million-Year-Old Rhino Tooth Provides Oldest Genetic Information Ever Studied

Researchers read the proteins preserved in the tooth enamel of an ancient rhino, a trick that may allow them to sequence fossils millions of years old

A photograph of a red slipped ware globular pot placed near the head of the skeleton that yielded ancient DNA. There are lines as well as indentations on the upper right side, just below the rim. The indentations on the body of the pot could be examples of ancient graffiti and/or "Indus script."

Rare Ancient DNA Provides Window Into a 5,000-Year-Old South Asian Civilization

The Indus Valley Civilization flourished alongside Mesopotamia and Egypt, but the early society remains shrouded in mystery

Excavation of the Philistine cemetery at Ashkelon.

When Ancient DNA Gets Politicized

What responsibility do archaeologists have when their research about prehistoric finds is appropriated to make 21st-century arguments about ethnicity?

Excavation of the Philistine cemetery at Ashkelon.

Ancient DNA Sheds New Light on the Biblical Philistines

A team of scientists sequenced genomes from people who lived in a port city on the Mediterranean coast of Israel between the 12th and 8th centuries B.C.

The specimen is the first (partial) carcass of an adult Pleistocene steppe wolf—an extinct lineage distinct from modern wolves—ever found

Cool Finds

A Perfectly Preserved 32,000-Year-Old Wolf Head Was Found in Siberian Permafrost

Given the head’s state of preservation, researchers are hopeful that they can extract viable DNA and use it to sequence the wolf’s genome

An ancient population of Arctic hunter-gatherers, known as Paleo-Eskimos, made a significant genetic contribution to populations living in Arctic North America today.

Ancient DNA Reveals Complex Story of Human Migration Between Siberia and North America

Two studies greatly increase the amount of information we have about the peoples who first populated North America—from the Arctic to the Southwest U.S.

New Research

China’s ‘CRISPR Babies’ May Be More Likely to Die Young

The mutation that was intended to make them resistant to H.I.V. has now been linked to a shorter life expectancy

Most of the World’s Macadamias May Have Originated From a Single Australian Tree

But this lack of genetic diversity could put cultivated macadamias at risk

Cool Finds

Burial Mound Found on Kindergarten Playground Was Used for 2,000 Years

Thirty sets of human remains from the mound in southwest France show locals buried their dead in the same spot from the Stone Age to the Iron Age

They're all good dogs.

New Research

Breathing Problems in Pugs and Bulldogs Might Have a Genetic Component

It might not be their smushed-up snouts after all

The synthetic DNA contains 61 codons, as opposed to the 64 typically found in living organisms

Scientists Create E. Coli Bacteria With Completely Synthetic Genome

The synthetic organisms appear to function much like their natural counterparts

Tastier Tomatoes May Be Making a Comeback Thanks to Genetics

A new analysis found that a flavor-making gene variant absent in most older variations of the fruit is increasing in frequency
