EU researchers have developed a graphene-enabled detector for terahertz light that is faster and more sensitive than existing room-temperature technologies. This can lead to a fully digital low-cost terahertz camera system. This could be as cheap as the camera inside the smartphone, since such a detector has proven to have a very low power consumption and is fully compatible with CMOS technology.

Detecting terahertz (THz) light is extremely useful for two main reasons. Firstly, THz technology is becoming a key element in applications regarding security (such as airport scanners), wireless data communication, and quality control, to mention just a few. However, current THz detectors have shown strong limitations in terms of simultaneously meeting the requirements for sensitivity, speed, spectral range, being able to operate at room temperature.

Secondly, it is a very safe type of radiation due to its low-energy photons, with more than a hundred times less energy than that of photons in the visible light range.

Indeed, Schindler stressed that Google would generate personalized Maps recommendations in “privacy-sensitive, opt-in ways.”

The company is betting that adding more data about places and businesses to Maps will lead people to spend more time on the service. As users expect more from Maps, Google has extra space to introduce more ads.

“We want to be able to highlight things that are around you and surface them nearby to you in a way that’s not disrupting your experience,’’ said Rajas Moonka, director of product management for Google Maps. Because so much of what users are looking for in Google Maps is commercial in nature, ads can be a helpful addition to the experience, he said.

Back in the late 1990s, a traveler from Lebanon to London would have noticed something interesting about telecommunications in the two countries, while many people in Lebanon owned a mobile phone, London was still accustomed to using red telephone boxes to make calls on the run. What caused such a difference? During the Lebanese Civil War, all landline infrastructures were destroyed, and the Lebanese leapfrogged to owning mobile phones. Fast-forward 20 years to today and one can see a similar pattern in many developing countries, where landlines and personal computers are bypassed for mobile internet. 5G is going to make that shift even more dramatic and in many other similar areas, technology is enabling us to bypass existing infrastructure and to rethink the way things are made.

Manufacturing cars is highly efficient and in most 21st century facilities you hardly see any people. Everything is done by robots on a moving assembly line. But it makes you wonder if such a factory setup would make sense for new product categories, which in the beginning are a novelty at best? For example, flying cars or Unmanned Aerial Vehicles ( UAV). The questions we should be asking: How are we going to do it cost-effectively and with similar automation as automotive factories? And can Additive Manufacturing help these novel product categories excel, cut costs and completely skip the assembly line altogether? Just like when Henry Ford created the first moving assembly line back in 1913, it was then a necessity for industrial production to take place. If we wish to cut costs, simplify assembly, reduce factory footprints and part counts, Additive Manufacturing starts becoming a necessity and as a result, we can start questioning the 100-year-old assembly line.

One day, phones will be made from stardust and unicorns. For now, though, we have four choices.

It’s a difficult choice: Go hungry or go it alone.

When soldiers are weighed down on the battlefield by food supplies and the heavy battery packs that power their communication equipment, they often choose to ditch the rations. It’s a sacrifice made to keep devices powered up and communication lines open in the field.

Smaller, longer-lasting batteries would help lighten a soldier’s load, so USC researchers are working with the U.S. Department of Defense to develop better batteries that weigh half as much as current power packs.

Switching your phone off for important meetings or trips to the cinema can be a pain in the ass. Victor Johansson has a solution, though: he’s designed the Escape Jacket, which features a Faraday cage in the inside pocket to immediately take your phone off the grid.

UK-based designer Johansson says that the concept is all about you-time. He explains:

South Korea will become the first country to commercially launch fifth-generation (5G) services as it rolls out the latest wireless technology with Samsung’s new 5G-enabled Galaxy S10.

Over the past twenty years, neuroscientists have been quietly building a revolutionary technology called BrainGate that wirelessly connects the human mind to computers and it just hit the world stage. Entrepreneurs such as Elon Musk and Mark Zuckerberg have entered the race with goals of figuring out how to get computer chips into everyone’s brains. The attention of Musk and Zuckerberg means the potential for giant leaps forward. But the question no one seems to be asking is whether our dependence on machines and technology has finally gone too far. Countries annually celebrate their independence from other countries, but it now seems we should start asking deeper questions about our personal independence.

60 Minutes recently ran a piece showing how engineers are using what scientists have learned about the brain to manipulate us into staying perpetually addicted to our smartphones. The anxiety most of us feel when we are away from our phone is real: During the 60 Minutes piece, researchers at California State University Dominguez Hills connected electrodes to reporter Anderson Cooper’s fingers to measure changes in heart rate and perspiration. Then they sent text messages to his phone, which was out of his reach, and watched his anxiety spike with each notification.

The segment revealed that virtually every app on your phone is calibrated to keep you using it as often and as long as possible. The show made an important point: a relatively small number of Silicon Valley engineers are experimenting with, and changing in a significant way, human behavior and brain function. And they’re doing it with little insight into the long-term consequences. It seems the fight for independence has gone digital.

We all know the feeling of a mobile phone vibrating in our hands when announcing an incoming call. If we perceive these vibrations so clearly, it is due to specialized receptors that transduce them into neural signals sent to our brain. But how does the latter encode their physical characteristics? To understand this, neuroscientists from the University of Geneva (UNIGE) have observed what happens in the brains of mice whose forepaws perceive vibrations. They discovered that neurons in the somatosensory cortex are activated in a manner similar to those in the sound-reactive auditory cortex. These results, published in the journal Nature, suggest that feeling a phone vibrate or hearing it ring is ultimately based on the same brain codes.

If you place a glass of water on your desk, you can probably see on its surface the concentric oscillatory motions created by the small movements that occur nearby. These oscillations are caused by vibrations that propagate through the floor, desk, glass and all other solid surfaces. These vibrations are also important sensory stimuli that we use to detect, for example, an approaching train or to identify the familiar step of our office neighbor. «We live surrounded by vibrations that are extremely important in how we perceive the world,» explains Daniel Huber at the Department of Basic Neurosciences at the UNIGE Faculty of Medicine, who led this work. «So we wanted to know how the brain perceives and represents them.».
