New brain-like transistor mimics human intelligence

Researchers develop transistor that simultaneously processes and stores information like the human brain. Transistor goes beyond categorization tasks to perform associative learning. Transistor identified similar patterns, even when given imperfect input. Previous similar devices could only operate at cryogenic temperatures; new transistor operates at room temperature, making it more practical.

This next generation blue light could potentially promote or hinder sleep on command

Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelengths. But now, researchers report that they have designed more 'human-centric' LEDs that could potentially enhance drowsiness or alertness on command.

This adaptive roof tile can cut both heating and cooling costs

In a new study, researchers present an adaptive tile, which when deployed in arrays on roofs, can lower heating bills in winter and cooling bills in summer, without the need for electronics.

Discovery of magnetic liquid crystal

A team of researchers succeeded at directly observing spin quadrupoles. This work was made possible through remarkable achievements over the last decades in synchrotron facility development.

New conductive, cotton-based fiber developed for smart textiles

A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.

Training algorithm breaks barriers to deep physical neural networks

Researchers have developed an algorithm to train an analog neural network just as accurately as a digital one, enabling the development of more efficient alternatives to power-hungry deep learning hardware.

Bowtie resonators that build themselves bridge the gap between nanoscopic and macroscopic

Two nanotechnology approaches converge by employing a new generation of fabrication technology. It combines the scalability of semiconductor technology with the atomic dimensions enabled by self-assembly.

Chemists create organic molecules in a rainbow of colors

Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.

New wearable communication system offers potential to reduce digital health divide

Researchers developed a wearable device that can transmit health data 2,400 times the distance of Wi-Fi without significant network infrastructure.

'Doughnut' beams help physicists see incredibly small objects

A new laser-based technique can create images of structures too tiny to view with traditional microscopes, and without damaging them. The approach could help scientists inspect nanoelectronics, including the semiconductors in computer chips.

Photonic chip that 'fits together like Lego' opens door to semiconductor industry

A new semiconductor architecture integrates traditional electronics with photonic, or light, components could have application in advanced radar, satellites, wireless networks and 6G telecommunications. And it provides a pathway for a local semiconductor industry.
