Reliably measuring whether rivers or lakes run out of air

Wastewater carries large quantities of organic substances into the rivers and lakes, leading to heavy growth of bacteria and oxygen deficiency. Measurement methods have so far been incapable of measuring this organic pollution ...

Distorted GPS signals reveal hurricane wind speeds

By pinpointing locations on Earth from space, GPS systems have long shown drivers the shortest route home and guided airline pilots across oceans. Now, by figuring out how messed up GPS satellite signals get when bouncing ...

Physicists create new 3D microchip

Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three dimensions. Currently, microchips can only pass digital information in a very ...

Improving speed measurements for cars, bullets

While today's law enforcement officers don't wear utility belts full of crimefighting gadgets like Batman, they do rely on a variety of state-of-the-art technologies to do their jobs efficiently and safely. Two of these devices—down-the-road ...

Fast magnetic imaging with diamond-based quantum sensor technology

Microscopic imaging of magnetic fields, enabled by quantum sensing, allows the measurement of the unique magnetic fingerprint of objects. This opens the door for fundamentally new applications in various fields such as materials ...
