The signals that cells use to switch genes on have remained almost unchanged across 2 billion years of evolution, but the ...

Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward.

Neurons transmit information to the next cell by converting electrical signals into chemical signals. A critical step in this ...

Optical frequency combs generate many evenly spaced light frequencies for applications such as optical clocks, precision spectroscopy, and high-speed communications. They are produced in compact Kerr ...

The Army successfully tested a cutting-edge electronic warfare system designed to disrupt enemy precision weapons. But key ...

Biologically plausible learning now reaches 96.7% on MNIST and 61.7% on CIFAR-10 without backpropagation, as Sakana AI ...

Artificial intelligence is consuming enormous amounts of energy, but researchers at the University of Florida have built a chip that could change everything by using light instead of electricity for a ...

Abstract: Improving the decoding performance of steady-state visual evoked (SSVEP) signals is crucial for the practical application of SSVEP-based brain-computer interface (BCI) systems. Although ...

The team over at Waves must be feeling particularly generous this week, as the software developer announces that it's releasing a bundle of seven free plugins that features a convolution reverb, FM ...

A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the ...
