The “slow motion” modes on modern smartphones crank up the speed of video recording so that when it’s played back at regular speed, the motion you see on the screen is slowed down. It’s a neat feature to mess around with, but slow motion capture has some very serious scientific applications as well. Capturing the microscopic world at high speeds can help researchers shed light on all kinds of interesting behaviors and phenomena that shape our reality.

Now, imaging specialists have built what is being called the fastest camera on the planet, allowing for the capture of movement at up to 10 trillion frames per second. Forget slowing down a video of a home run at your kid’s softball game, this incredible contraption can slow down light itself.

A new paper published in Light: Science & Applications explains how the camera works, and boy is it complicated. To put it in its most basic terms, the camera uses laser pulses so ultra-fast that they are measured in quadrillionths of a second and combines those frames with images captured from a second camera moving at the same speed, allowing for high-quality images generated 10 trillion times every second.

Tesla is shaking up the automotive industry. But which of Tesla’s products and features are doing the disrupting, and who will be affected? A recent article by Benedict Evans delves into the details of this automotive disruption with comparisons to similar shake ups in the tech industry.

Evans uses the disruptive wave that Apple unleashed on Palm, Nokia, and other makers of previous-generation cell phones as an analogy. “When Nokia’s people looked at the first iPhone, they saw a not-great phone with some cool features that they were going to build too, being produced at a small fraction of the volumes they were selling,” he writes. “When many car company people look at a Tesla, they see a not-great car with some cool features that they’re going to build too, being produced at a small fraction of the volumes they’re selling.”

But can Tesla be considered the Apple of the auto industry, and if so, what would that mean? Disruption occurs when a new technology or concept changes the basis of competition in a field. However, not every new technology turns out to be disruptive. “Some things do not change the basis of competition enough, and for some things the incumbents are able to learn and absorb the new concept instead,” writes Evans, noting that business professor Clay Christensen calls this “sustaining innovation” as opposed to “disruptive innovation”.

Our smartphones are cold, passive devices that usually can’t move autonomously unless they’re falling onto our faces while we’re looking at them in bed. A research team in France is exploring ways to change that by giving our smartphones the ability to interact with us more (via New Scientist). MobiLimb is a robotic finger attachment that plugs in through a smartphone’s Micro USB port, moves using five servo motors, and is powered by an Arduino microcontroller. It can tap the user’s hand in response to phone notifications, be used as a joystick controller, or, with the addition of a little fuzzy sheath accessory, it can turn into a cat tail.

Get ready for the next generation of wifi technology: Wi-fi 6 (for so it is named) is going to be appearing on devices from next year. But will you have to throw out your old router and get a new one? And is this going to make your Netflix run faster? Here’s everything you need to know about the new standard.

A brief history of wifi

Those of you of a certain age will remember when home internet access was very much wired—only one computer could get online, a single MP3 took half an hour to download, and you couldn’t use the landline phone at the same time.

In the past, early adopters embraced inanimate technology, like smartphones. But what happens when transhumanism stops being sci-fi conjecture and goes mainstream? Will we be so ready to upgrade ourselves?

The display screens of modern televisions, cell phones and computer monitors rely on liquid crystals—materials that flow like liquids but have molecules oriented in crystal-like structures. However, liquid crystals may have played a far more ancient role: helping to assemble Earth’s first biomolecules. Researchers reporting in ACS Nano have found that short RNA molecules can form liquid crystals that encourage growth into longer chains.

Scientists have speculated that life on Earth originated in an “RNA world,” where RNA fulfilled the dual role of carrying genetic information and conducting metabolism before the dawn of DNA or proteins. Indeed, researchers have discovered catalytic RNA strands, or “ribozymes,” in modern genomes. Known ribozymes are about 16–150 nucleotides in length, so how did these sequences assemble in a primordial world without existing ribozymes or proteins? Tommaso Bellini and colleagues wondered if liquid crystals could help guide short RNA precursors to form longer strands.

To find out, the researchers explored different scenarios under which short RNAs could self-assemble. They found that at high concentrations, short RNA sequences (either 6 or 12 nucleotides long) spontaneously ordered into liquid crystal phases. Liquid crystals formed even more readily when the researchers added magnesium ions, which stabilized the crystals, or polyethylene glycol, which sequestered RNA into highly concentrated microdomains. Once the RNAs were held together in liquid crystals, a chemical activator could efficiently join their ends into much longer strands. This arrangement also helped avoid the formation of circular RNAs that could not be lengthened further. The researchers point out that polyethylene glycol and the chemical activator would not be found under primordial conditions, but they say that other molecular species could have played similar, if less efficient, roles.

The Commute tab for Maps first popped up in a limited rollout in early September, but starting today it’s rolling out to users on Android and iOS. Google says that this new feature is designed to help you “take control over your commute.” It built the feature with the fact that, in many cities across North America, rush hour traffic can result in a commute that takes up to 60% longer than expected.

With the new Commute tab, Google Maps can provide live data on traffic to help you best manage your daily trip to work. It automatically accounts for accidents or heavy traffic and can help you better budget your time to account for that or provide alternate routes. Android users will have notifications on these updates sent to their device before getting caught in the delay.
