What if we could use a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope? This would allow us to measure the chemical properties of materials at unprecedented time and spatial resolutions.

This new technique has now been developed by physicists at the University of California, Irvine, according to a statement released by the institution on Friday.

“This project represents an advance in both the measurement technique and the scientific question the approach allowed us to explore,” said in the press release co-author of the new study Wilson Ho, Donald Bren Professor of physics & astronomy and chemistry.

Teledyne FLIR Defense has announced the partnership with MFE Inspection Solutions to integrate the FLIR MUVE C360 multi-gas detector on Boston Dynamics’ Spot robot and commercial unmanned aerial systems (UAS). The integrated solutions will enable remote monitoring of chemical threats in industrial and public safety applications.

The compact multi-gas detector can detect and classify airborne gas or chemical hazards, allowing inspection personnel to perform their job more safely and efficiently with integrated remote sensing capabilities from both the air and ground.

MUVE C360 is designed to operate on Boston Dynamics‘Spot mobile robot, which can autonomously inspect dangerous, inaccessible, or remote environments. It is also compatible with common commercial UAS systems, which allow operators to fly the C360 into a scene to perform hazard assessments in real-time.

Existing memristive devices cannot be reconfigured to meet the diverse volatile and non-volatile switching requirements, and hence rely on tailored material designs specific to the targeted application, limiting their universality. “Reconfigurable memristors” that combine both ionic diffusive and drift mechanisms could address these limitations, but they remain elusive. Here we present a reconfigurable halide perovskite nanocrystal memristor that achieves on-demand switching between diffusive/volatile and drift/non-volatile modes by controllable electrochemical reactions. Judicious selection of the perovskite nanocrystals and organic capping ligands enable state-of-the-art endurance performances in both modes – volatile (2 × 10⁶ cycles) and non-volatile (5.6 × 10³ cycles). We demonstrate the relevance of such proof-of-concept perovskite devices on a benchmark reservoir network with volatile recurrent and non-volatile readout layers based on 19,900 measurements across 25 dynamically-configured devices.

Our brains are awash with various unsung chemical heroes, making sure the electrical signals traveling all over the place don’t get out of control.

A new mouse study has now detailed the function of a pair of proteins vital to maintaining this balance – this could help us better understand a range of neurological disorders from epilepsy to schizophrenia.

The two proteins – Rab3-interacting molecule 1 (RIM1) and an enzyme called serine arginine protein kinase 2 (SRPK2) – work together to modify the transmission of information across the gaps between nerves called synapses.

This is a 10-minute version with my picks on an hour-and-a-half interview on the longevity science made by Rhonda Patrick to Morgan Levine.

The link to the entire interview, which took place on April 12, 2022, is in the description of the video.

She gives a great analogy of slowing aging versus reversing aging, and I did not realize Yamanaka Factors were not so perfect in current use.

In this video Eleanor talks about the her view on Longevity Escape Velocity and reprogramming with Yamanaka factors and some of the issues around this technology.

This new technique can also be applied to analysis of two-dimensional materials which have the potential to play a role in advanced energy systems, electronics and quantum computers.

Today in Science, the researchers in UCI’s Department of Physics & Astronomy and Department of Chemistry describe how they positioned two bound atoms of hydrogen in between the silver tip of the STM and a sample composed of a flat copper surface arrayed with small islands of copper nitride. With pulses of the laser lasting trillionths of a second, the scientists were able to excite the hydrogen molecule and detect changes in its quantum states at cryogenic temperatures and in the ultrahigh vacuum environment of the instrument, rendering atomic-scale, time-lapsed images of the sample.
