New discovery shows human cells can write RNA sequences into DNA — ScienceDaily

Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell. That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository of recipes, so they can be read more efficiently into proteins. But polymerases were thought to only work in one direction DNA into DNA or RNA. This prevents RNA messages from being rewritten back into the master recipe book of genomic DNA.…

Tumblr for a new user on iOS I have…

We’re currently rolling out an opt-in beta for a new post editor on web which will leverage the Neue Post Format behind the scenes. It’s been a very long time coming – work on the Neue Post Format began in 2015 and was originally codenamed “Poster Child”, and it was borne out of a lot of things we learned dealing with the previous new post editor we released on web around that time. Over the years, the landscape of how…

Drone with 3D mapping tech gives first responders near real-time data

Credit: ResponDrone Project The international ResponDrone project has integrated into its situation awareness system for emergency situations a near real-time 3D mapping solution to provide on-site emergency teams with tools that will help them to better evaluate their working environment. The upgraded ResponDrone System will provide accurate location information to first responders, especially in relation to infrastructure, when called on to deal with a fire, flood or any other natural disaster. ResponDrone has signed an agreement with Hivemapper to integrate…

Bird-like wings could help drones keep stable in gusts

Need a DIY project? How to modify a 3D printer to make food or ceramics

While the pandemic has restricted us from doing many activities we like, household hobbies such as DIY, baking and crafts have become more popular. Now there’s a way to combine all of these skills to create something entirely new. What you will need, however, is a 3D printer. 3D printers will print anything made of plastic, quickly and in any shape you like. But there’s a lot they cannot do. You couldn’t 3D-print pasta shaped like your children’s favorite cartoon…

Common diabetes drug shows promise as treatment for COVID-19 lung inflammation — ScienceDaily

Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans. Metformin works by lowering glucose production in the liver, reducing blood sugar levels that, in turn, improve the body’s response to insulin. But scientists have also noted that metformin possesses anti-inflammatory properties, though the basis for this activity was not known. In a study published online…
