How Scientists Stored a Movie Inside DNA
If you thought flash drives were small, wait until you see this: Researchers have encoded the data to make a short video into the DNA molecules of bacteria. They also...

Colonizing Mars may require humanity to tweak its DNA
Genetic engineering may be a big part of our future on Mars. If humanity is ever going to settle down on Mars, we may need to become a little less human....

Identical Twins Accumulate Genetic Differences in the Womb
DNA replication errors during cell division cause monozygotic twins to diverge from each other even during the earliest stages of development, a new study finds. Rather than having exactly the...

COVID-19’s Effects on the Brain
Autopsy studies have yet to find clear evidence of destructive viral invasion into patients’ brains, pushing researchers to consider alternative explanations of how SARS-CoV-2 causes neurological symptoms. When epidemics and...

We’re not prepared for the genetic revolution that’s coming
When humans’ genetic information (known as the genome) was mapped 15 years ago, it promised to change the world. Optimists anticipated an era in which all genetic diseases would be...

The Promise of mRNA Vaccines
Long before Moderna’s and Pfizer’s COVID-19 shots, scientists had been considering the use of genetically encoded vaccines in the fight against infectious diseases, cancer, and more. Earlier this month, the...

Identical twins don’t share 100% of their DNA
Identical twins form from the same egg and get the same genetic material from their parents — but that doesn't mean they're genetically identical by the time they're born. That's...

CRISPR gene editing used to store data in DNA inside living cells
DNA inside living bacterial cells has been edited with CRISPR technology to encode and store information. This could be a step towards developing a new medium for long-term data storage. Life’s genetic...

Gene editing could destroy herpes viruses living inside you
Almost all of us carry one form or another of the herpes virus, and the consequences can be far worse than the occasional cold sore. Herpes viruses also cause shingles and...
