News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells.

They also found that common cholesterol-lowering drugs protected zebrafi...

Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.

News: Quanergy's New $250 Solid-State LiDAR Could Bring Self-Driving to the Masses

One of the big hurdles when equipping vehicles with sensors for autonomous driving is the cost. For example, the Light Detection and Ranging (LiDAR) sensors that power many versions of self-driving car technology are pricey, currently ranging from around several thousand dollars up to $85,000 per sensor—and vehicles often need multiple sensors to see enough of what is going on around them to drive safely.

How To: Create a Reusable Burner OS with Docker, Part 1: Making an Ubuntu Hacking Container

Containers are isolated software instances representing applications, servers, and even operating systems—complete with all of their dependencies, libraries configuration files, etc.—and they're taking over the corporate world. The ephemeral, portable nature of containers help them stay current and speedy, and they can work on pretty much any computer, virtual machine, and cloud.
