DNA Computers are in the Lab Now

Although it isn’t very real-world practical, researchers at Cal Tech have produced a DNA-based programmable computer. Spectrum reports that the system executes programs using a set of instructions written in DNA using six bits. Like any programmable computer, this one can execute many programs, but so far they run 21 …read more

Open-Source Biology and Biohacking Hack Chat

Join us on Wednesday at noon Pacific time for the open-source biology and biohacking Hack Chat!

Justin Atkin‘s name might not ring a bell, but you’ve probably seen his popular YouTube channel The Thought Emporium, devoted to regular doses of open source science. Justin’s interests span a wide range, literally from the heavens above to the microscopic world.

His current interest is to genetically modify yeast to produce spider silk, and to perhaps even use the yeast for brewing beer. He and the Thought Emporium team have been busy building out a complete DIY biology lab to support the effort, …read more

Hacked Heating Instruments for the DIY Biology Lab

[Justin] from The Thought Emporium takes on a common molecular biology problem with these homebrew heating instruments for the DIY biology lab.

The action at the molecular biology bench boils down to a few simple tasks: suck stuff, spit stuff, cool stuff, and heat stuff. Pipettes take care of the sucking and spitting, while ice buckets and refrigerators do the cooling. The heating, however, can be problematic; vessels of various sizes need to be accommodated at different, carefully controlled temperatures. It’s not uncommon to see dozens of different incubators, heat blocks, heat plates, and even walk-in environmental chambers in the …read more

Françoise Barré-Sinoussi: Virus Hunter

It was early 1983 and Françoise Barré-Sinoussi of the prestigious Pasteur Institute in Paris was busy at the centrifuge trying to detect the presence of a retrovirus. The sample in the centrifuge came from an AIDS patient, though the disease wasn’t called AIDS yet.

Just two years earlier in the US, a cluster of young men had been reported as suffering from unusual infections and forms of cancer normally experienced by the very old or by people using drugs designed to suppress the immune system. More cases were reported and US Centers for Disease Control and Prevention (CDC) formed a …read more
