The robot can drive on various surfaces such as concrete or packed soil and carry up to three times its own weight in equipment such as a camera or sensors.

Imagine a tiny robot that can move on its own, powered by light and radio waves. It can carry a camera, a sensor, or a Bluetooth device and transmit data over long distances. It can navigate through different terrains and environments and follow light sources to keep going. It sounds like science fiction, right?

Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and NASA’s Hubble Space Telescope has caught the action.

The nebula, called the Cygnus Loop, forms a bubble-like shape that is about 120 light-years in diameter. The distance to its center is approximately 2,600 light-years. The entire nebula has a width of six full moons as seen on the sky.

Astronomers used Hubble to zoom into a very small slice of the leading edge of this expanding supernova bubble, where the supernova blast wave plows into surrounding material in space. Hubble images taken from 2001 to 2020 clearly demonstrate how the remnant’s shock front has expanded over time, and they used the crisp images to clock its speed.

The combination of nuclear magnetic resonance with first-principles calculations uncovers the stacking patterns of layers of a quantum material—information that could enable a deeper understanding of the material’s behavior.

A group of researchers from Tohoku University, Massachusetts Institute of Technology (MIT), Rice University, Hanoi University of Science and Technology, Zhejiang University, and Oak Ridge National Laboratory have proposed a new mechanism to enhance short-wavelength light (100–300 nm) by second harmonic generation (SHG) in a two-dimensional (2D), thin material composed entirely of commonplace elements.

Since UV light with SHG plays an important role in semiconductor lithography equipment and medical applications that do not use fluorescent materials, this discovery has important implications for existing industries and all optical applications.

Details of the research were published in the journal ACS Nano on August 29, 2023. The study was selected to be featured on the cover.

A color-changing system inspired by the wings of butterflies can also help scientists provide compound eye vision to robots, but why do scientists want robots to see like insects?

Would you like to try a T-shirt whose color changes with the weather? How about a bandage that alerts you by changing its color when an infection occurs at the site of an injury?

Researchers unveil a revolutionary material, tungsten oxide hydrate, enabling dynamic windows that adapt to light and temperature, boosting energy efficiency.

Dynamic windows have long been the dream of architects and engineers, promising buildings that adapt to varying light and temperature conditions.

Now, researchers from NC State University have taken a giant leap forward in this field by unveiling a revolutionary material known as tungsten oxide hydrate. This innovation could pave the way for the next generation of dynamic windows, offering building occupants the ability to switch their windows between three distinct modes: transparency, infrared light blocking, and glare control, according to a university release.

YouTuber Lucas VRTech has designed and built a pair of finger-tracking VR gloves using just $22 in materials — and he’s released all the details on the build so others can make their own.

The challenge: We use our hands to manipulate objects in the real world, but in VR, users typically have to use controllers with buttons and joysticks.

That breaks some of the immersion, limiting the use of VR for not only gaming, but also applications like therapy and job training.

The material can help scientists understand the origins of the Earth.

Using a metallic grating and infrared light, researchers have uncovered a light–matter coupling regime where the local coupling strength can be 3.5 times higher than the global average for the material.
