3D-printed artificial intelligence running at the speed of light—from object classification to optical component design

Deep learning is one of the fastest-growing machine learning methods that relies on multi-layered artificial neural networks. Traditionally, deep learning systems are implemented to be executed on a computer to digitally learn data representation and abstraction, and perform advanced tasks, comparable to or even superior than the performance of human experts. Recent successful applications of deep learning include medical image analysis, speech recognition, language translation, image classification, as well as addressing more specific tasks, such as solving inverse imaging problems.

Looking inside the lithium battery's black box

Researchers report the use of SRS microscopy, a technique widely used in biomedical studies, to explore the mechanism behind dendrite growth in lithium batteries, the first team of material scientists to directly observe ion transport in electrolytes. They were able to see not only why lithium dendrites form but also how to inhibit their growth. Visualizing ion movement could help improve the performance of electrochemical devices, from batteries to fuel cells to sensors.

LHC accelerates its first 'atoms'

Protons might be the Large Hadron Collider's bread and butter, but that doesn't mean it can't crave more exotic tastes from time to time. On Wednesday, 25 July, for the very first time, operators injected not just atomic nuclei but lead "atoms" containing a single electron into the LHC. This was one of the first proof-of-principle tests for a new idea called the Gamma Factory, part of CERN's Physics Beyond Colliders project.

Optical neural network demo

Researchers have made a silicon chip that distributes optical signals precisely across a miniature brain-like grid, showcasing a potential new design for neural networks.

New algorithm could help find new physics

Scientists have developed an algorithm that could provide meaningful answers to condensed matter physicists in their searches for novel and emergent properties in materials.

NASA Gives $1.4 Million to Help Minority-Serving Colleges Develop New STEM Courses

The MUREP Innovations in Space Technology Curriculum (MISTC) awards align with the priorities of the agency’s Space Technology Mission Directorate (STMD), which is responsible for developing the crosscutting, pioneering new technologies and capabilities the agency needs for current and future missions.
