Scientists at EPFL and IBM Research have developed a compact optical amplifier based on a photonic chip that vastly outperforms traditional optical amplifiers in both bandwidth and efficiency. This breakthrough could reshape data center interconnects, AI accelerators, and high-performance computing.

Studying spinal cord injuries requires a material that can transmit clear signals yet remain flexible for when patients move around. Researchers at Binghamton University, State University of New York think they have hit upon a solution that will offer the best of both requirements. In a recently published paper in Nature Communications, Assistant Professor Siyuan Rao and her team have created a hydrogel electrode that includes conductive carbon nanotubes to monitor nerve activity.

This recent research clarifies this matter thanks to the design of a new model of brain computational analysis, called CHARM (Complex Harmonics Decomposition). It is the most accurate model to date for examining the functions of long-distance brain connections, which link neurons that are far apart and play a fundamental role in the brain dynamics that are activated when making critical decisions. It is also the first model to apply quantum mechanics as an instrument for analysing the brain.

Four crew members will embark on a new long-duration science expedition when they launch to the International Space Station (ISSInternational Space Station) on a SpaceX Falcon 9 rocket and Dragon spacecraft as part of NASA’s SpaceX Crew-10 mission. While on station, the crew will engage in a wide variety of research sponsored by the ISS National Laboratory®, including materials and physical sciences experiments and biomedical research. Findings from these investigations will benefit humanity and drive commerce in low Earth orbit(Abbreviation: LEO) The orbit around the Earth that extends up to an altitude of 2,000 km (1,200 miles) from Earth’s surface. The International Space Station’s orbit is in LEO, at an altitude of approximately 250 miles..

In developing hearts, cells shuffle around, bumping into each other to find their place, and the stakes are high: pairing with the wrong cell could mean the difference between a beating heart and one that falters. A study publishing on March 12 in the Cell Press journal Biophysical Journal demonstrates how heart cells go about this “matchmaking” process. The researchers model the intricate movements of these cells and predict how genetic variations could disrupt the heart development process in fruit flies.

SAN ANTONIO — March 12, 2025 — Four small suitcase-sized spacecraft, designed and built by Southwest Research Institute headquartered in San Antonio, launched from Vandenberg Space Force Base in California on March 11. NASA’s Polarimeter to Unify the Corona and Heliosphere, or PUNCH, constellation has spread out in a low-Earth orbit along the day-night line, providing a clear view in all directions for its two-year primary mission.
