Superluminal Jets and Time Reversibility

Astrophysicists Jon Hakkila of the College of Charleston and Robert Nemiroff of the Michigan Technological University have published research indicating that blasts that create gamma-ray bursts may actually exceed the speed of light in surrounding gas clouds, but do so without violating Einstein's theory...

Ringing of a Newborn Black Hole

If Albert Einstein's theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself "ring" in the aftermath, producing gravitational waves much like a struck bell reverberates sound waves. Einstein predicted that the particular...

A set of five tiny fundamental parts can be assembled into a wide variety of functional devices including a tiny “walking” motor that can move back and forth across a surface or...

Neural Lander Uses AI to Land Drones Smoothly

Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are...

The characteristics of hybrid drives present a practical solution when a position needs to be detected with high precision

In the digital age, the measurement of rotation of a mechanical shaft on a motor or a rotating instrument knob needs to be done quickly and efficiently....

Smartphone App Programs Robots

A smartphone app was developed that allows a user to easily program any robot to perform a mundane activity such as picking up parts from one area and delivering them to another. The app, called VRa, uses...

While most cars today run on 12-volt DC batteries, cars in the future will run on 48 volts. This increased voltage could affect ball bearing performance.

A high-sensitivity and low-noise MEMS accelerometer was developed using multi-layer metal structures composed of multiple metal layers. The accelerometer achieves 1 μG level resolution that has...
