RNA origami: Artificial cytoskeletons to build synthetic cells

Sciencedaily.com 

With the long-term goal of creating living cells from non-living components, scientists in the field of synthetic biology work with RNA origami. This tool uses the multifunctionality of the natural RNA biomolecule to fold new building blocks, making protein synthesis superfluous. In pursuit of the artificial cell, a research team has cleared a crucial hurdle. Using the RNA origami technique, they succeeded in producing nanotubes that fold into cytoskeleton-like structures.

ICE Has An Internet Surveillance Power Tool That Keeps Tabs On More Than 200 Websites

This has been part of the so-called “enhanced screening” protocols for several years now, deployed against foreign residents upon arrival in this nation, whether at border crossings or international airports where they’re just flying in for a short-term […]



First documented sighting of a group of bowhead whales in Canada's Churchill River Estuary

Phys.org 

In the summer of 2020, researchers from the University of Manitoba set up a time-lapse camera overlooking the Churchill River Estuary. The goal of their research was to understand the interactions between beluga whales and marine vessels. However, what they captured was unexpected—a group of bowhead whales, a phenomenon never before documented in the area.
