Unlimited capacity in wireless networks with massive MIMO

Massive MIMO is an antenna technology that is considered the most promising for future superfast 5G networks, although researchers have until now believed that there is an upper limit for how much data can be transferred. ...

A milestone in petahertz electronics

In a semiconductor, electrons can be excited by absorbing laser light. Advances in the past decade have enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10-15 s). Now, physicists at ...

The occurrence of magnetism in the universe

Flows of molten metal can generate magnetic fields. This so-called dynamo effect creates cosmic magnetic fields, like those found on planets, moons and even asteroids. In the coming years, researchers are conducting a unique ...

Marine exploration sensing with light and sound

Oceanic sensor networks that collect and transmit high-quality, real-time data could transform the understanding of marine ecology, improve pollution and disaster management, and inform multiple industries that draw on ocean ...

Plants overcome hunger with the aid of autophagy

Researchers at Tohoku University have found that plants activate autophagy in their leaf cells to derive amino acids that are used for survival under energy-starved conditions. The findings show that amino acid utilization ...
