DNA

Some people are genetically built to require less sleep than the rest of us.

Why Do Some People Thrive on So Little Sleep?

Short sleepers cruise by on four to six hours a night and don’t seem to suffer ill effects

DNA on Earth is built from sugars with a property known as right-handedness. Though left-handed sugars aren't used by any known life, scientists can create them—but now, researchers say they shouldn't.

Scientists Warn of an ‘Unprecedented Risk’ From Synthetic ‘Mirror Life,’ Built With a Reverse Version of Natural Proteins and Sugars

So-called mirror cells could rampage through our ecosystems, food supply and immune systems, experts say, potentially without existing barriers to protect against them

The genetic basis for orange cats' coloration has long been unknown to scientists.

Geneticists Solve the Mystery of Why Some Cats Are Orange—and Why They Tend to Be Males

Two new, preliminary papers identify a gene related to a cat’s coloration. The work also explains why tortoiseshell and calico cats tend to be females

Divers recovered rye seeds from the James R. Bentley shipwreck in Lake Huron.

Scientists Are Trying to Make Whiskey Using Rye Seeds That Were Submerged in a Lake Huron Shipwreck for Nearly 150 Years

Divers, distillers and researchers recently recovered grain from the “James R. Bentley,” a wooden schooner that sank during a storm in 1878

Fat tissue, as seen here under a scanning electron micrograph, maintains a "memory" of obesity, new research suggests.

Fat Cells Retain a ‘Memory’ of Obesity, Making It Hard to Lose Weight and Keep It Off, Study Suggests

Obesity leads to DNA alterations that affect gene activity and linger after weight loss, a finding that researchers say could help reduce stigma around the disease

Four plaster casts from the House of the Golden Bracelet were made in 1974.

New Research

DNA Evidence Is Rewriting the Stories of Victims Who Perished in Pompeii Nearly 2,000 Years Ago

A new study has shattered historians’ long-held assumptions about some of the people who died in Mount Vesuvius’ eruption in 79 C.E.

Researchers performed DNA testing on the bones highlighted in this image.

New Research

Archaeologists Are Bewildered by a Skeleton Made From the Bones of at Least Eight People Who Died Thousands of Years Apart

Found in a cremation cemetery in Belgium, the skeleton includes bones dating to the Neolithic period and a Roman-era skull, according to a new study

The man's remains were found in 1938 in a well by Sverresborg Castle, near the modern-day city of Trondheim.

New Research

Scientists Think a Skeleton Found in a Well Is the Same Man Described in an 800-Year-Old Norse Text

The remains were discovered during excavations in 1938. Now, researchers have learned new information about his identity by analyzing DNA from his tooth

Researchers are trying to "bring back" the thylacine, or Tasmanian tiger, a species that has not been officially recorded since 1936.

A 110-Year-Old Pickled Thylacine Head Helped Build the Most Complete Ancient Genome to Date, Says ‘De-Extinction’ Company

Colossal Biosciences reports it extracted DNA and RNA from the Tasmanian tiger specimen, a key step forward in its effort to create a modern proxy of the extinct species. Other scientists are calling for data to back up the claim

Scientists traced the history of AMY1, the gene that's responsible for the production of amylase, an enzyme that helps break down complex carbohydrates.

Can’t Get Enough Carbs? That Craving Might Have Started More Than 800,000 Years Ago

New research traces the genetic underpinnings of the enzyme amylase, which helps humans digest starches and sugars

The lions have been housed as taxidermy specimens at the Field Museum in Chicago since 1925.

Two Lions Went on a Man-Eating Spree in 1898. Now, DNA Evidence Reveals Their Diets

The notorious predators, nicknamed the “Man-Eaters of Tsavo,” terrorized railway workers in Kenya for roughly nine months

David Baker, Demis Hassabis and John M. Jumper shared the Nobel Prize in Chemistry on Wednesday for their work on protein structure.

Scientists’ Work on Protein Structure, Which Governs All Aspects of Life, Wins Nobel Prize in Chemistry

David Baker, Demis Hassabis and John M. Jumper revealed how amino acids shape protein structure, a finding that could aid in drug discovery

The Nobel Prize in Physiology or Medicine was awarded to Victor Ambros and Gary Ruvkun, who together discovered microRNA.

American Scientists Win Nobel Prize in Medicine for ‘Groundbreaking’ Gene Discovery Made by Studying Worms

Victor Ambros and Gary Ruvkun discovered microRNA, tiny molecules that play a crucial role in how cells develop, paving the way for new treatments for diseases

James Fitzjames was a captain aboard the HMS Erebus. Now, researchers have identified his remains with DNA analysis.

DNA Reveals Identity of Officer on the Lost Franklin Expedition—and His Remains Show Signs of Cannibalism

Researchers recently identified James Fitzjames, a captain on the ill-fated HMS Erebus that went looking for the Northwest Passage in 1845

This "everlasting" crystal contains the entire human genome, recorded using ultra-fast lasers, and is meant to instruct future species on how to create humans.

In Case Humans Go Extinct, This Memory Crystal Will Store Our Genome for Billions of Years

Scientists have created “a form of information immortality” meant to instruct future species on how to recreate humans. But who, or what, will find it?

Construction of the famous stone statues of Rapa Nui, called moai, was previously thought to have contributed to the island's population collapse.

Easter Island’s Ancient Population Never Faced Ecological Collapse, Suggests Another Study

New DNA analysis adds to growing research indicating the famous Pacific island did not collapse from overuse of resources before the arrival of Europeans

Researchers discovered Thorin's fossilized remains in 2015 in a cave in southern France.

Ancient DNA Reveals Neanderthal Group Was Isolated for 50,000 Years

A new study, based on the remains of a Neanderthal nicknamed Thorin, is shaking up what archaeologists long thought about these early humans in Europe

Recent genetic research could be used to produce plants without prickles, making it easier for gardeners to pluck roses without getting jabbed.

Scientists Identify the Gene Behind Thorny Roses and Other Prickly Plants

A recent study could pave the way to cultivating various thornless plants, making them easier to grow and potentially more widely available

Grave 109 at Oakington is a rare triple burial, holding the remains of a female infant, a young woman (left) and an older woman (center). 

Archaeologists Uncover the Real Story of How England Became England
