Researchers have demonstrated a compact optical wireless transmitter that delivers very high data rates while consuming significantly less energy than conventional WiFi systems. The chip-scale platform integrates a 5 × 5 array of tiny semiconductor lasers with custom beam-shaping optics, enabling parallel data transmission and controlled light distribution for multiuser indoor environments. In experiments, the system achieved an aggregate data rate of more than 360 gigabits per second over a two-meter free-space link, with energy consumption per bit roughly half that of state-of-the-art WiFi. The results highlight the potential of optical wireless communication as an energy-efficient complement to radio-based networks for future high-capacity indoor connectivity.

Understanding how representative currently known proteins are of the overall potential diversity can help inform strategies for a wide range of applications, including therapeutic, biocatalysis, or biomaterials development. Published in PNAS, an OIST-led international team investigated the relationship between protein evolution and sequence space, identifying the limiting factors behind protein diversification. Their findings reinforce theories of DNA recombination as a driving force of ancestral protein formation and highlight the limitations of many cutting-edge AI protein design methods.

AMHERST, Mass. — Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink the size of quantum computers, an achievement aligned with the shrinking of integrated microprocessors in the 1970s, 80s and 90s that allowed computers to move from room-sized behemoths to today’s ultrathin smartphones.

Virtual reality feels more “real” when users can touch a physical prop, but most haptic proxies follow a one-object-one-model approach that is costly and hard to deploy. A new fabric topological haptic proxy (FTHP) integrates origami-inspired constraints and embedded sensing fibers so a single cloth can switch among flat, folded and transforming states for different interactions. A lightweight neural network decodes the signals and achieves about 92.4% action recognition accuracy.

The chemical composition of meteorites and asteroids acts as a kind of fingerprint, providing information about the origin of the building materials that formed the Earth. 

Using a new analysis of existing data, the researchers show that this material must exclusively come from the inner solar system. 

The material that formed the Earth is similar to that found on Mars and the asteroid Vesta. The Earth is thus part of a trend line extending from the Sun. 

This close relationship also enables predictions to be made about the composition of Venus and Mercury, from which we have no known samples. 

Six partners from research and industry, including Helmholtz-Zentrum Berlin (HZB), the Fritz-Haber-Institute of the Max Planck Society (FHI), BASF, Dunia Innovations, Siemens Energy, and the Technical University Berlin are launching a joint project to accelerate the catalyst discovery. The German Federal Ministry for Science, Technology and Space (BMFTR) is providing €30 million in funding for ASCEND (Accelerated Solutions for Catalysis using Emerging Nanotechnology and Digital Innovation). The research initiative targets the defossilisation of energy-intensive industries while safeguarding industrial competitiveness, with a focus on the chemical sector. The five-year project will start on 1^st April 2026.

Researchers have developed a new brain–computer interface that records neural signals from the brain’s lateral ventricle, a fluid-filled cavity traditionally used only for clinical drainage. Using a lantern-inspired expandable electrode, the system delivers stable, high-quality recordings for months and decodes memory-guided decisions with up to 98% accuracy in rats. The approach reduces immune response compared with conventional cortical implants and opens a new route for long-term, minimally invasive brain–machine interfaces.

A new study reveals that surface water ice in the Moon’s permanently shaded regions (PSRs) is less abundant than previously anticipated. Published recently in Science Advances, the research provides the most detailed look yet into the lunar PSRs where sunlight cannot reach directly, suggesting that while ice may exist, it is likely present in low concentrations or small, isolated pockets.
