If you’ve watched enough reruns of shows like CSI, Bones, and Law and Order, you probably know by now that when forensic specialists find DNA evidence, the suspect is often identified within the next couple of minutes—as soon as the team sticks the results of DNA analysis into a computer program. Although the real life process isn’t quite as speedy, DNA certainly has been the highest bar for identification in forensics. But when it comes to hair samples of missing persons or those found at crime scenes, sequencing the proteins in those locks may work better than DNA.
Researchers in the United Kingdom have discovered how HIV’s protective shell helps it invade healthy cells without being detected by the immune system.
Could our genes continue thriving even though we have passed on? A new animal study suggests that genes continue to work up to 48 hours after death.
Last year, a biotech startup called Clear Labs performed DNA testing on a bunch of hot dogs and discovered that they often contain more than the label advertises. The same company has now used its arsenal of molecular technologies to break down America’s other favorite meat-on-a-bun product: burgers. Once again, there are some unsavory surprises.
Apologies to people keen on reviving extinct dinosaurs, but researchers have never recovered dinosaur DNA, which is necessary for cloning. But, intriguingly, they have found fragments of mystery DNA in dinosaur bone, experts told Live Science.
The killer read his Bible. He drank. Heavily. It was a fall night in 2006, when Bradley Waldroup walked out of his rural trailer in southeastern Tennessee, carrying his .22 caliber hunting rifle. His estranged wife and her friend, Leslie Bradshaw, had just pulled up to drop off the Waldroups’ four children. Waldroup began arguing with his wife and Bradshaw, who was unloading the car. Drawing his gun, Waldroup shot Bradshaw eight times, killing her. He used a knife to cut her head open.
Researchers from Temple University have used the CRISPR/Cas9 gene editing tool to clear out the entire HIV-1 genome from a patient’s infected immune cells. It’s a remarkable achievement that could have profound implications for the treatment of AIDS and other retroviruses.
