RAADcity: The marketplace of your future.

This is the first in a series of in-depth articles examining China’s efforts to build a stronger, domestic semiconductor industry amid rising trade tensions with US.

After several decades and billions of dollars of investment, only 16 per cent of semiconductors used in China today are manufactured domestically.

Researchers at the University of Waterloo have developed a cheaper and more efficient method for Internet-of-Things devices to receive high-speed wireless connectivity.

With 75 billion Internet of Things (IoT) devices expected to be in place by 2025, a growing strain will be placed on requirements of wireless networks. Contemporary WiFi and cellular networks won’t be enough to support the influx of IoT devices, the researchers highlighted in their new study.

Millimeter wave (mmWave), a network that offers multi-gigahertz of unlicensed bandwidth—more than 200 times that allocated to today’s WiFi and cellular networks, can be used to address the looming issue. In fact, 5G networks are going to be powered by mmWave technology. However, the hardware required to use mmWave is expensive and power-hungry, which are significant deterrents to it being deployed in many IoT applications.

As vital as clean water is for human life, unfortunately it’s not always easy for people to get enough. Adding insult to injury, the stuff is basically always floating around us in the air, unreachable. Now, researchers from the University of California Berkeley have developed a device that can wring drinkable amounts of water out of even the driest air.

The team says this new water harvester can produce more than 1.3 L (5.4 US cups) of water per day per kilogram (2.2 lb) of a particular water-absorbing material. This can be done even at less than 40 percent relative humidity. That’s not a whole lot of water, but it is more than enough to keep a person alive, if a situation was that dire.

The harvester was put to the test over three days in the Mojave Desert. During that time, the device produced 0.7 L (3 cups) of water per kg of material, and even on the driest day the harvester managed to wring 200 ml (6 oz) of water out of air that had an extremely low relative humidity of just seven percent.

Nobody can say for sure. Hundreds of years ago, atoms were thought to be the smallest particles in the universe. But since then, scientists like Indu invented tools such as particle detectors, accelerators, and colliders that can study them in great detail. Thanks to these tools, they have discovered a whole set of elementary particles, which are the smallest particles we know about today.

Quarks and gluons are two such elementary particles that combine to form protons and neutrons. These, along with electrons, make up atoms. Atoms constitute most of the matter that we know about—from trees and stones to animals and birds. But Indu was amazed to learn that there is a whole set of particles that exist but are not part of atoms at all. One such elementary particle is the neutrino, Indu’s absolute favourite! Neutrinos are everywhere. They whiz across the universe—from the sun and from elsewhere in outer space. Many of them reach us here on earth too. So, how common are they?

Tell you what. Snap your fingers right now. Done? In the amount of time it took you to do this, billions of neutrinos have passed through your thumb! Neutrinos may be tiny, but they are very important because our universe is full of them. Knowing the mass of a neutrino will help Indu understand the rate at which the universe is expanding.

Tesla is planning to ramp up installation of its new solar roof, but it needs to figure out a way to reduce installation time.

Now a new patent shows a possible solution by producing and installing solar roof tiles in jointed groups.

General Motors is the latest automaker reported to be working on solid-state lithium batteries, thanks to a $2 million grant from Uncle Sam.

The money is part of a larger grant to develop more fuel-efficient powertrains, CNET reported. The company is expected to use the rest of the money to develop a lighter-weight, more efficient engine for medium duty trucks, perhaps to replace the company’s 6.2-liter V-8.

Reaching a major milestone, engineers have successfully connected the two halves of NASA’s James Webb Space Telescope for the first time at Northrop Grumman’s facilities in Redondo Beach, California. Once it reaches space, NASA’s most powerful and complex space telescope will explore the cosmos using infrared light, from planets and moons within our solar system to the most ancient and distant galaxies.
