Inside The Forensic Lab That Fights Crime And Counterfeits With DNA

What you’re looking at is me, being blasted by a fog machine. It’s not a prop for a rave or a haunted house; it’s vapor laced with custom DNA particles that could prove I was at the scene of a crime. And it’s just one way a cutting-edge security firm is using life’s building blocks to detect counterfeits and bust criminals.


The World's First Handheld DNA Amplifier Is A Genetics Lab In A Box

DNA sequencing is crucial for identifying and tracking nasty viruses like E. coli and the flu. But current tabletop-size DNA sequencing machines aren’t readily portable. Researchers at the University of Otago in New Zealand have a solution in a brick-sized DNA sequencer that connects wirelessly to a smartphone or laptop.


DIY Diagnosis: How One Woman Uncovered Her Own Genetic Flaw

When Kim Goodsell discovered that she had two extremely rare genetic diseases, she taught herself genetics to help find out why.


This Is Why We Have Brains In Our Heads And Not Our Bums

Video: This video explains why our brains are at the end of our bodies in our heads. Evolutionary advantage led to sensory organs clustered together around animals’ eating ends and early brains developed. Only later did animals start to protect these assets with skulls and then develop other advantages such as jaws.


Mystery Illnesses Could Now Be Diagnosed With A Rapid DNA Test

When we think of medicine, we usually think of the treatment: drugs, surgery, therapy. But before all that comes the diagnosis — a tricky proposition when symptoms are confusing and information scant. Now for the first time ever, doctors were able to use rapid DNA sequencing to identify an obscure bacterium in time to save a boy’s life.


Artist Regrows Van Gogh's Ear Using His DNA

Artist Diemut Strebe made a living replica of Vincent van Gogh’s ear, grown from genetic samples provided by Lieuwe van Gogh, the great-great-grandson of Vincent’s brother Theo. They share about 1/16th of the same genes, including the Y-chromosome, passed down the male lineage.


How England's Yeast Vault Saved A Brewery After A Disastrous Flood

A commercial brewery is really a factory. Raw ingredients like grain and water go in one end, flow through pipes and tanks, and beer comes out the other side. But you could gut and replace all those pipes and tanks, switch from one grain supplier to another, swap out the walls and the controllers, and the same beer would still flow from the taps, metaphorically speaking.


This Mechanical Nano-Lance Is One Hundredth The Size Of A Human Hair

You may think this looks like the surface of the Death Star, but it’s actually a microscopic device that delivers DNA into the nucleus of a single cell. The process has been awesomely dubbed metamorphic nanoinjection by Brigham Young University scientists, and it benefits all kinds of genetic research for diseases like cancer and Alzheimer’s.


Scientists Have Created 'Alien' DNA

After 15 years of work, scientists have successfully created a living cell that contains two unnatural DNA building blocks. The breakthrough brings us one step closer to being able to synthesise cells that can produce drugs on demand. It even opens the door to a future where we could create life that’s unlike anything ever found on Earth.


DNA Sequences Can Trace Your Ancestors To Within 50km

DNA sequencing can already tell us a lot about our ancestors. But a new technique developed by an international team of scientists now allows them to pinpoint a person’s geographical origin — going back 1000 years.
