DNA

Frozen seafood in the lab, ready for DNA testing.

The DNA Detectives That Reveal What Seafood You’re Really Eating

Genetic sequencing allows scientists to uncover increasingly prevalent seafood fraud

We All Experience Smells Differently From One Another

A difference of a single amino acid on one gene can cause that person to experience a smell differently than someone with another amino acid

One of the ancient human fossils found in Spain's La Sima de los Huesos.

Scientists Just Sequenced the DNA From A 400,000-Year-Old Early Human

The fossil, found in Spain, is mysteriously related to an ancient group of homonins called the Denisovans, previously found only in Siberia

Baby Mice Can Inherit Fear of Certain Smells From Their Parents

But researchers are far from pinning down the mechanism by which this may be possible, or what specific roles epigenetics plays in human disease

The Toxins That Affected Your Great-Grandparents Could Be In Your Genes

Biologist Michael Skinner has enraged the chemical community and shocked his peers with his breakthrough research

San Francisco-based entrepreneur Antony Evans plans to insert genes from bioluminescent bacteria into a species of flora as a first step to creating glowing trees.

Creating a New Kind of Night Light: Glow-in-the-Dark Trees

A group in California is starting to engineer plants that could one day replace streetlights

Eric D. Green is the director of the National Human Genome Research Institute.

Cracking the Code of the Human Genome

The Work Is Only Beginning on Understanding the Human Genome

Ten years ago, scientists released a map of our genetic blueprint. But, as Eric D. Green explains, there are many more mysteries left to unravel

Nitrogen-cooled tissue samples will represent half the life on earth.

What Genomic Research Can Tell Us About the Earth’s Biodiversity

Smithsonian scientists are gathering wildlife tissue samples from around the world to build the largest museum-based repository

The genetic blueprints of an athlete are as important as training.

How Olympians Could Beat the Competition by Tweaking Their Genes

The next horizon in getting that extra athletic advantage may not be steroids, but gene therapy

A monarchist displays images of the Romanovs. Many Russians regard the Romanovs, canonized by the Orthodox Church in 2000, as martyrs.

Resurrecting the Czar

In Russia, the recent discovery of the remains of the two missing Romanov children has pitted science against the church

"Now it's off to the races," botanist Dave Erickson says of a project to barcode 250 species of plant life on Plummers Island.

Cracking the DNA Code

On a small island near Washington, D.C., Smithsonian researchers have found a genetic code that could revolutionize botany

Conventional wisdom held that only a huge stretch of DNA could function as a gene. The discovery of an overlooked genetic entity upends that view. Croce "was stunned."

High Hopes for a New Kind of Gene

Scientists believe that microRNA may lead to breakthroughs in diagnosing and treating cancer

A US Air Force Boeing 707 disturbs a colony of sooty terns during takeoff.

The Perils of Bird-Plane Collisions

When airlines want to investigate dangerous bird strikes against planes, they turn to the head of the Smithsonian’s Feather Identification Lab

Born with a disease that has robbed her eyesight, Alisha Bacoccini (being examined by surgeon Albert Maguire) is undergoing experimental gene therapy at the University of Pennsylvania. If she weren't legally blind, says the 20-year-old massage therapist, she would want to be a forensic scientist.

Gene Therapy in a New Light

A husband-and-wife team’s experimental genetic treatment for blindness is renewing hopes for a controversial field of medicine

Jocelyn Kaiser graduated from Princeton University with a degree in chemical engineering. She now writes for Science magazine and is the author of Gene Therapy in a New Light, which appears in Smithsonian's January 2009 issue.

The ‘Secret Jews’ of San Luis Valley

In Colorado, the gene linked to a virulent form of breast cancer found mainly in Jewish women is discovered in Hispanic Catholics

How Breast Cancer Genes Work

Though we may talk of cancer as one disease, skin cancer has little in common with pancreatic cancer and breast cancer is something else entirely

When it dives, the platypus closes its eyes, ears and nostrils and finds its food through electrical receptors in its bill that detect the movement of small prey.

On the Evolutionary Gold Mine Down Under

What the platypus and other Australian species reveal about genetics
