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...

Chemical studies show that dust particles originated in a low-temperature environment. Experiments conducted at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) helped to confirm that samples of interplanetary particles – collected from Earth’s upper atmosphere and believed to originate from comets – contain dust leftover from the initial formation of the solar system.

An international team, led by Hope Ishii, a researcher at the University of Hawaii at Manoa (UH Manoa), studied the particles’ chemical composition using infrared light at Ber...

Over the last decade, bariatric surgeons have made strides in performing weight loss surgery that not only reverses obesity but can also reverse type 2 diabetes in patients with both conditions. Despite dramatic improvements in quality of life and diabetes remission, the number of patients who pursue surgery remains relatively low, according to Ali Tavakkoli, MD, co-director of the Center for Weight Management and Metabolic Surgery at BWH...

Electrical dipole activity detected in a quantum material unlike any other tested. A theorized but never-before detected property of quantum matter has now been spotted in the lab, a team of scientists reports. The team proved that a particular quantum material can demonstrate electrical dipole fluctuations – irregular oscillations of tiny charged poles on the material – even in extremely cold conditions, in the neighborhood of -450 degrees Fahrenheit.

The material, first synthesized 20 years ago, is called k-(BEDT-TTF)2Hg(SCN)2 Br. It is derived from organic compounds, but behaves like a metal...
