Water-Born Glass Shows Transparent, Adhesive, Self-Healing Properties
Researchers from Tel Aviv University have created a type of glass that is formed spontaneously when a powdered substance comes into contact with water at room temperature. The glass is a strong adhesive, fully transparent, and has self-healing properties. It is expected to have applications in a broad range of industries, from satellite communications to medical fields.

Programmable Sensor Provides Fast, High-Quality Imaging of Neural Changes
To study brain functions like memory, neuroscientists track the electrical communications of neurons. These voltage changes can be subtle and happen on a millisecond timescale. A programmable image sensor from MIT could improve the ability to measure these signals, potentially allowing greater insight into how they affect brain function.

Measuring Starlight with an Ultrafast Laser: Astrocomb Development for the Extremely Large Telescope
Tue, Aug 6, 2024 10:00 AM - 11:00 AM EDT
In this webinar, Yuk Shan Cheng of Heriot-Watt University explores the important role of the Extremely Large Telescope's (ELT) ANDES spectrograph and its need for a high-precision frequency calibrator in order to pursue exciting ventures. She focuses on the development of astrocombs, which are laser frequency comb systems that can provide thousands of stable, atomically referenceable, and evenly spaced calibration lines. Despite their demonstrated success in labs and various telescopes worldwide, integrating astrocombs into modern telescope facilities presents challenges, including aligning their mode spacings with the spectrograph's resolving power and achieving broad spectral coverage, particularly in the UV-blue/green wave band. This presentation covers the approaches to these challenges, recent implementation at the Southern African Large Telescope, and advancements in astrocomb technology at Heriot-Watt University, including the development of the first continuous UV-blue/green astrocomb.
