The myriad of processes occurring in biological cells may seem unbelievably complex at first glance. Yet, in principle, they are merely a logical succession of events, and could even be used to form digital circuits.

Researchers have now developed a molecular switching circuit made of DNA, which can be used to mechanically alter gels, depending on the pH. DNA-based switching circuits could have applications in soft robotics, say the researchers in their article in Angewandte Chemie.

DNA is a long molecule that can be folded and twisted in various ways. It is comprise of a backbone with bases that stick outward in order to pair up with their counterparts in other DNA strands. When a series of these matching pairs comes together, they form a twisted, ladder-like double strand — the familiar DNA double

Show, don’t tell: how gaming contributes to education and science

Games and game-like elements have been used to help train human minds throughout history. Sports ‘games’ were created to get people to train and keep fit, board games like chess were made to educate soldiers on war strategies, and card games were used to help teach math.

Learning to game

As technology became more advanced, video games picked up this mantle. Turtle Academy released one of the first real educational games called Logo Programming back in 1967 to teach people how to program.

Many influential tech figures, including Mark Zuckerburg and Larry Page, say that playing video games from a young age helped them develop an interest in computing, providing them with the skills they needed to create their own programs.

Previously, gaming was seen by many as a distraction. However, its reputation has been transformed over the past decade. With the

Portals in Vilnius, Lublin give science fiction view hundreds of miles apart

A civic-minded team of scientists, city leaders and (we’re pretty sure) sci-fi fans has just hatched a cool idea that’s one part Stargate, one part Star Trek, and all parts awesome: placing a pair of high-tech public “portals” in two European cities, giving anyone who’s strolling past a real-time look into life as it’s happening hundreds of miles apart.

The pair of giant circular windows into other places have gone online in Lithuania and Poland, relying on massive video screens and the internet to give people a visual, if not quite physical, connection. The debut installation from a team called the PORTAL project, they’re the first of what the team hopes is several more two-way portals connecting far-away people and places across the world. Both portals are in high-traffic public areas; one is near a train station in the Lithuanian capital of Vilnius; the other is located
