A ban on clinical trials involving gene editing rules out the controversial procedure done in China. But it also prevents procedures that could offer couples a chance for healthy children without genetic disorders.
Home DNA testing has made it easy and affordable for millions of people to learn about their ancestry. Now, police are using this genetic information to identify suspects in unsolved crimes.

Despite privacy concerns over police use of DNA uploaded to ancestry websites, many people are just excited that their genetic material could get a killer off the streets.
Spider glue is actually a specialized silk protein.

The glue that gives spider webs their stickiness is a form of spider silk protein. Researchers can imagine cool uses for a synthetic version – but had to wait for the tricky glue gene to be sequenced.
Screening millions of healthy people for their risk of disease can be cost-effective. But it raises ethical and regulatory concerns.

Estimating our ancestry is hard – because our backgrounds are much more mixed up than we thought. So don’t take your DNA ancestry test results literally: they’re just a prediction.
What’s the best way to put the brakes on current research?

Scientists and ethicists have called for a five-year moratorium on editing human genes that will pass on to future generations. Yes, society needs to figure out how to proceed – but is this the best way?

According to current regulations, animals that have been genetically edited, like pigs or cows, are considered drugs. What are the consequences of such rules on American livestock and agriculture?
When you share your genetic data – even with the NHS – you don’t know where it will end up, or how it will be used.
Revolutionary technologies like CRISPR are founded on discoveries uncovered through basic research that attracts very little attention.

On average, important new lab techniques like CRISPR take 23 years to develop – but there is a public expectation that scientific breakthroughs occur quickly and efficiently.
Police have powerful new genetic tools. How are we going to regulate their use? A Genetic Data Protection Act is one solution to ensure confidence in the way DNA is accessed and used.
One way to tackle this violent crime is through DNA profiling.
