Summary: Zooming out to image larger areas of the brain while using fMRI technology allows researchers to capture additional relevant information, offering a better understanding of neural interplay.

Researchers have learned a lot about the human brain through functional magnetic resonance imaging (fMRI), a technique that can yield insight into brain function. But typical fMRI methods may be missing key information and providing only part of the picture, Yale researchers say.

Here are my thoughts on attending the 2022 Tesla Annual Shareholders Meeting.

Just as human counts are incomplete, so are animal counts. But the first worldwide compilation of animal cases is a start at understanding the extent of human-to-animal transmission, scientists say.

The researchers wanted to create robots that could pick up and sort molecules within a designated space. This makes it possible for DNA molecules to serve as the building blocks for 3D nanostructures that self-assemble in a predetermined shape. Tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

This enabled the researchers to design a nano-robot composed of three DNA origami structures. To help it maneuver within the designated space, the robot had a “leg” with a pair of feet. An “arm” with a “hand” allowed it to carry cargo, and a third component was added to tell the hand when a specific drop-off point had been reached so it would know to release the cargo. It allows researchers to carry out the entire design truly in 3D. Earlier design tools only allowed creation in 2D, forcing researchers to map their creations into 3D.

The software helps researchers design ways to take tiny strands of DNA and combine them into complex structures with parts like rotors and hinges that can move and complete a variety of tasks, including drug delivery. The robot will also enable researchers to more precisely determine important signaling pathways for a variety of biological and pathological processes that are stimulated at the cellular level during the application of force.

Holographic teleportation could solve the many issues that 2D virtual meetings have these days. Besides, you could simply beam into work while at home.

Researchers at the University of Western Ontario recently completed the world’s first-ever international holographic teleportation.

In the past, the city relied on complaints to identify people not following the rules, but new digital water meters installed city wide means the city doesn’t have to wait for someone to call.

The meters send water data back wirelessly. Customers can now monitor their daily and hourly water use through an app, alerting them to high usage rates or leaks.

The city though is also able to see high use rates at times when it doesn’t add up. Rates of 300-gallons per hour on a Monday, indicated someone probably had the sprinklers on, triggering a notice.

“Pamela” is an uncrewed surface vehicle (USV) developed as an entrepreneurial idea at the Norwegian University of Science and Technology (NTNU) for sampling a variety of surface water particles, from microplastic to plankton to salmon lice. The USV is a joint effort by an interdisciplinary team—Andrea Faltynkova, a Ph.D. candidate at the Department of Biology, and Artur Zolich, a postdoc at the Department of Engineering Cybernetics.

Faltynkova studies microplastics in the ocean. Microplastics are bits of plastic smaller than 5 mm, which is roughly the size of the end of a pencil. While researchers know that microplastics can have negative effects on marine or freshwater organisms, there’s less known about how they affect human health. But studying microplastics is a challenge because of the nature of the substance itself, she says.

“Microplastics are so heterogeneous. It’s a very large, diverse group of particles. Not only that but they are very unevenly distributed. Microplastic is not like other dissolved pollutants that can be detected even in small quantities of water or soil. If you go and you take a liter from the sea, and there’s no plastic in it, can you conclude that there is no plastic in the sea?” she asked.

The challenge: The building and construction sector is responsible for a big chunk of global carbon emissions. A lot of those emissions come from the production of cement, which is the second most consumed material on the planet behind water.

Cement produces emissions in two main ways. One is through the chemical reactions that occur while sintering limestone and other materials to make “clinker,” a key component of cement. The other comes from using fossil fuels to heat up kilns to very high temperatures.
