Why scholars have created global guidelines for ancient DNA research

Studying ancient DNA in Africa is valuable for understanding human evolution, population migrations, and human history locally, regionally and globally.

Messenger RNA: how it works in nature and in making vaccines

Thanks to the collaborative efforts of governments, funding agencies, academia, biotech and pharmaceutical companies, large-scale manufacturing of mRNA drug products is becoming a reality.

Is it possible to recreate dinosaurs from their DNA?

Ever since moviegoers saw the first ‘Jurassic Park,’ millions have wondered if scientists could make a dinosaur in the lab.

Mixed-ancestry genetic research shows a bit of Native American DNA could reduce risk of Alzheimer’s disease

Using a technique called admixture mapping, researchers can leverage the diversity of people with mixed ancestry to look for hard-to-find genetic risk factors for diseases like Alzheimer’s disease.

DNA analysis reveals the identity of a member of the doomed Franklin Arctic expedition

129 officers and crew died during the 1845 Franklin Northwest Passage expedition. DNA analysis from their remains of members can reveal the identity of the men who perished during the journey.

Microfluidics: The tiny, beautiful tech hidden all around you

Electronics are not the only technology to have been miniaturized. Using the strange behavior of fluids in tiny spaces, microfluidic devices are critical to medicine, science and the modern world.

DNA ‘Lite-Brite’ is a promising way to archive data for decades or longer

DNA has been storing vast amounts of biological information for billions of years. Researchers are working to harness DNA for archiving data. A new method uses light to simplify the process.
A complete human genome, seen here in pairs of chromosomes, offers a wealth of information, but it is hard connect genetics to traits or disease. HYanWong/Wikimedia Comons

Scientists are on a path to sequencing 1 million human genomes and use big data to unlock genetic secrets

The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.
