A new world record in wireless transmission, promising faster and more reliable wireless communications, has been set by researchers. The total bandwidth of 145GHz is more than five times higher than the previous wireless transmission world record. A new world record in wireless transmission, promising faster and more reliable wireless communications, has been set by

Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to conventional technologies. KAIST researchers have overcome the limitations of existing

Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are expensive. However, cheaper alternatives have been developed -- for example, cobalt-manganese catalysts. They have a high activity and are stable over a long period of time. The decisive factor for these characteristics is their manganese content. Why manganese plays this essential

Researchers have developed photoswitching molecules that reversibly change properties not only with light, but also with heat. They showed that the molecules can be used as a rewritable recording medium as well. In this age of cloud storage, few people are backing up data on CD-RWs. The technology to rewrite data on compact discs was

How long do free neutrons live until they decay? This has been a hotly debated topic, because different measurement techniques lead to different results. A possible new solution has now been proposed: All the results can be explained, assuming there are different neutron states with different lifetimes. Neutrons are among the basic building blocks of

Researchers have developed a new method using the Allen Telescope Array to search for interplanetary radio communication in the TRAPPIST-1 star system. A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to

With heart attacks, every second counts. A new blood test diagnoses them in minutes rather than hours and could be adapted as a tool for first responders and people at home.

Engineers have developed a new system for full-body motion capture -- and it doesn't require specialized rooms, expensive equipment, bulky cameras or an array of sensors. Instead, it requires only a smartphone, smartwatch or earbuds. Northwestern University engineers have developed a new system for full-body motion capture -- and it doesn't require specialized rooms, expensive

Experts have announced that the Sun has reached its solar maximum period, which could continue for the next year. Scientists will not be able to determine the exact peak of this solar maximum period for many months because it's only identifiable after they've tracked a consistent decline in solar activity after that peak. However, scientists

Researchers explore how the domesticated flightless silkworm moth (Bombyx mori), a prominent insect model in olfactory research, uses wing flapping to manipulate airflow, enhancing their ability to detect distant pheromones. These findings highlight how moths guide pheromones to their odor sensors in antennae, and suggest potential applications for designing advanced robotic systems for odor source

Researchers have unveiled a vision system inspired by feline eyes to enhance object detection in various lighting conditions. Featuring a unique shape and reflective surface, the system reduces glare in bright environments and boosts sensitivity in low-light scenarios. By filtering unnecessary details, this technology significantly improves the performance of single-lens cameras, representing a notable advancement

Researchers produced 3D-printed, semiconductor-free logic gates, which perform computations in active electronic devices. As they don't require semiconductor materials, they represent a step toward 3D printing an entire active electronic device. Active electronics -- components that can control electrical signals -- usually contain semiconductor devices that receive, store, and process information. These components, which must
