Functionalization of Polymer Networks for Diverse Applications

While silicon has been the go-to material for sensor applications, could polymer be used as a suitable substitute since silicon has always lacked flexibility to be used in specific applications? This is what a recent grant from the National Science Foundation hopes to address, as Dr. Elsa Reichmanis of Lehigh University was recently awarded $550,000 to investigate how polymers could potentially be used as semiconductors for sensor applications, including Internet of Things, healthcare, and environmental applications.

“We’ll be creating the polymers that could be the building blocks of future sensors,” said Dr. Reichmanis, who is an Anderson Chair in Chemical Engineering in the Department of Chemical and Biomolecular Engineering at Lehigh University. “The systems we’re looking at have the ability to interact with ions and transport ionic charges, and in the right environment, conduct electronic charges.”

Project Astra demo | Solving math problems

Watch Project Astra factorise a maths problem and even correct a graph. All shot on a prototype glasses device, in a single take in real time.

Project Astra is a prototype that explores the future of AI assistants. Building on our Gemini models, we’ve developed AI agents that can quickly process multimodal information, reason about the context you’re in, and respond to questions at a conversational pace, making interactions feel much more natural.

Altered States of Consciousness More Common Than Believed in Mind-Body Practices

Summary: A new study finds that altered states of consciousness (ASCs), like those experienced during meditation, are more common than previously thought. 45% of respondents reported experiencing ASCs at least once, often leading to positive outcomes.

However, a significant minority also reported negative or even life-threatening suffering, highlighting the need for better support and understanding of these experiences.

Citizen Scientists help Discover Record-Breaking Exoplanet in Binary Star System

A team of astronomers and citizen scientists has discovered a planet in the habitable zone of an unusual star system, including two stars and potentially another exoplanet.

The planet hunters spotted the Neptune-like planet as it crossed in front of its host star, temporarily dimming the star’s light in a way akin to a solar eclipse on Earth. This “transit method” usually identifies planets with tight orbits, as they are more likely to follow paths that put them between Earth and their host star and, when following such paths, move into light-blocking positions more frequently. That’s why this newly discovered planet is considered unusually far out, with the planet taking 272 days to lap its star.

Furthermore, the star is now by far the brightest one known to host a transiting planet in the habitable zone where liquid water can exist.
