Scientists at Tokyo Institute of Technology have designed and fabricated a tiny, but incredibly fast, reliable, and accurate 28-GHz transceiver meant for stable high-speed 5G communications. The fabricated transceiver trumps previous designs in various regards by taking a new approach for beam steering.

The importance of wireless communications is evident in modern societies, and thus, a lot of work has been done on 5G communications as it is the upcoming big step in mobile networks...

Our immune system sees Neu5GC as foreign and antibodies are made to attack it. This cancause inflammation and may promote cancer cell growth.

Neu5Gc, a non-human sialic acid sugar molecule common in red meat that increases the risk of tumor formation in humans, is also prevalent in pig organs, with concentrations increasing as the organs are cooked, a study by researchers from the UC Davis School of Medicine and Xiamen University School of Medicine has found. The research suggests that Neu5Gc may pose a significant health hazard among those who regularly consume organ meats from pigs.

Neu5Gc is naturally found on cell surfaces in most mammals but not in humans. It gets incorporated into human cells by eating meats, organs and some dairy products...

A new highly efficient power amplifier for electronics could help make possible next-generation cell phones, low-cost collision-avoidance radar for cars and lightweight microsatellites for communications. 5G mobile devices expected around 2019 will require improved power amplifiers operating at very high frequencies...

The future of wireless technology—from charging devices to boosting communication signals—relies on the antennas that transmit electromagnetic waves becoming increasingly versatile, durable and easy to manufacture. Researchers at Drexel University and the University of British Columbia believe kirigami, the ancient Japanese art of cutting and folding paper to create intricate three-dimensional designs, could provide a model for manufacturing the next generation of antennas.

Recently published in the journal Nature Communications, research from the Drexel-UBC team showed how kirigami—a variation of origami—can transform a single sheet of acetate coated with conductive MXene ink into a flexible 3D microwave antenna whose transmission frequency can be adju...
