National Geographic has a nice video (as well as a long story by Carl Zimmer) about scientists who are trying to learn more about the way the brain works by slicing mice brains into incredibly thin sections, fore to aft, and then using scans of those slices to create what amounts to a wiring diagram. The goal is to see how all the parts connect and, hopefully, get a better idea of how they all work together.
The video is lovely, with some great shots of lab work and an animated tour of the mouse brain slices. The animation looks, at first, like a time-lapse thing, but it's actually more like driving down a highway and watching buildings on the roadside appearing, becoming larger, and then shrinking in the rearview. Really great stuff! It also underlines a bit why I'm pretty skeptical of Ray Kurzweil's singularity. Or, at least, his estimations of how long it will take for scientists to understand our brains well enough that they could be replicated digitally.
Russian scientist Denis Rebrikov claims that he’s begun a gene-editing process to eventually enable couples who both carry a specific genetic mutation that causes deafness to birth children who can hear. Rebrikov formerly announced his effort to use the CRISPR tool for gene editing to create babies resistant to HIV. From Nature: In his e-mail […]
Caltech theoretical physicist Sean Carroll, author of Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime, explains the concept of a “dimensions” at five different levels of complexity. Dr. Carroll sure has a big brane.
In 1936, the Tasmanian tiger (Thylacinus cynocephalus) was declared to be extinct. Yet in the last three years, there have been eight reported sightings according to Tasmania’s Department of Primary Industries, Parks, Water and Environment. I hope it’s true. From CNN: While stories abound that some continue to live in the remote wilds of Tasmania, […]
Everybody could use a little improvement, especially those of us on the hunt for new careers. Each job requires a different set of skills, and that list can change from year to year or even month to month as new technologies emerge. When you’re in that race and need to learn fast, the old model […]
In recent years, natural language processing technology and language translation technology have advanced greatly. The trouble is, language translation software typically comes in the form of apps. And while your mileage may vary on their usefulness, they share one thing in common: a serious drain on the battery for your smartphone, the very thing you’ll […]
