Optogenetics Shows Relationship Between Brain and Gut Health
The brain-gut connection is known to influence hunger and mood, and it has also been associated with neurological and other disorders. To explore the signaling that occurs between these two organs, scientists at MIT integrated light sources, thermal sensors, microelectronics, and microfluidics in a device that enables stable bioelectronic interfaces with the brain and gastrointestinal tract in mice.

Compact, Single-Mode THz QCLs Get Boost from BICs
A team at Nanyang Technological University (NTU) developed an electrically pumped, topological, bulk quantum cascade laser (QCL) that operates in the terahertz (THz) frequency range. The THz QCL is governed by a mechanism known as bound states in the continuum (BICs). BICs are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. BICs can confine light with a theoretically infinite Q factor, which can improve light-matter interaction.

Confronting the Drug Epidemic with Portable Spectroscopy
Thu, Jul 6, 2023 1:00 PM - 2:00 PM EDT
Portable spectrometers have the potential to be a powerful tool for combatting the modern illicit drug trade in the field. The most significant advantage of portable spectrometers over other field tests is their capability to provide confirmatory analysis, which is rapid, reliable, and creates a reviewable record. Although no single portable spectrometer can analyze all samples, for example from bulk to trace or pure substances to complex mixtures, each modern instrument has its advantages and limitations with regard to the detection and identification of illicit drugs. Ultimately, a toolbox approach is needed to ensure that the right tool is used for the right job in the right way. Brooke Kammrath and Pauline Leary highlight applications of portable spectroscopy and spectrometry in field detection of illicit drugs which both have notable effects on the delivery of improved criminal justice.
