Quantum Squeezing Boosts Frequency Comb Sensitivity for Rapid Detection
Optical frequency comb lasers are used to detect toxic airborne substances ranging from methane leaks to the COVID-19 virus. Rapid detection can protect everyone in the vicinity of the leak from harm.
“Say you were in a situation where you needed to detect minute quantities of a dangerous gas leak in a factory setting,” Scott Diddams, professor at the University of Colorado Boulder (CU Boulder), said. “Requiring only 10 minutes versus 20 minutes can make a big difference in keeping people safe.”

Polymer Optical Fibers for Optogenetics Reduce Inflammation Risk
To deliver light to the brain safely and efficiently, a research team at the Technical University of Denmark designed tapered optical fibers made with soft, biocompatible polymer. The tapered fibers are optimized for light-based neural stimulation techniques like optogenetics. They could be used in studies to develop treatments and interventions for a range of neurological conditions.
The tapered fibers have a conical shape that allows light to leak from the sides of the fiber along the length of the tapered tip. The conical design increases the volume that can be illuminated, enabling homogeneous light delivery to a large volume as well as spatially resolved illumination, while being minimally invasive.
“Unlike standard...

Magneto-Optics Increases Photonic Processing Efficiency for AI
A platform for in-memory photonic computing using magneto-optic material has the potential to offer efficient, nonvolatile data processing with unlimited read/write capabilities and sub-nanosecond programming speeds. The magneto-optic memory platform was developed by researchers from the University of California, Santa Barbara (UCSB) and several international institutions. It addresses multiple limitations of existing photonic processing techniques.
Data-intensive applications like AI require ever greater computational power, while at the same time, the computing capacity of digital hardware has begun to flatten. Optical solutions use less energy and process data faster than traditional, electronic-based processing techniques.

New Metal Foams Enable World’s Brightest X-Ray Source
By combining the National Ignition Facility (NIF)’s X-ray laser and ultralight metal foams, researchers at Lawrence Livermore National Laboratory (LLNL) have produced the brightest X-ray source to date — about twice as bright as previous solid metal versions.
These ultrabright, high-energy X-rays can be used to image and study extremely dense matter, like the plasmas created during inertial confinement fusion.
LLNL scientist Jeff Colvin compared the source to the machine used to find cavities by a dentist.
“Your dentist's machine creates an electron beam that is crashed into a heavy metal plate. The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays,” he...

Time-Shared Optical Tweezers Simplify Study of Viscoelasticity and Aging
A technique to study the link between physiological aging and disease, from the Institute of Photonic Sciences (ICFO), uses single-laser-based optical tweezers to measure the viscoelasticity of biological materials as they mature.
In biology, changes in viscoelasticity can lead to cancer, neurodegenerative disorders, and other diseases. Knowledge of the viscoelasticity and other rheological properties of intracellular organelles, cells, and whole tissues is central to understanding their physiological functions. Knowledge of how changes to viscoelasticity affect cellular health could help speed diagnosis and drug development.
Optical tweezers are well-suited to obtaining the material properties of biological materials because...

Snapshot Video Rate Hyperspectral Imaging Excels in Environmental Applications
Hyperspectral imaging is widely favored for a broad range of applications in the industrial, life sciences, and space imaging sectors. The technology combines the capabilities of imaging and spectroscopy in a single instrument, and is differentiated from traditional RGB imaging, which provides three channels of visible colors across an image. By contrast, hyperspectral imaging provides a complete spectrum with tens or even hundreds of bands, usually extending outside of the visible and in some cases even beyond the NIR band (Main Image). It enables users to obtain valuable spectral information as a result, which can be used for image classifications, real-time detection, and surveillance.
Even as technological advances have led to...

Scalable Error-Correction Signals Forthcoming Efficiency Gains for Quantum Compute
Quantum computers hold tremendous promise, and the potential to solve a range of complex problems which are currently intractable due to the limitations of today’s super-computers. These problems span the fields of quantum chemistry and condensed matter physics — which have direct applications in crucial research areas such as drug discovery and the design of materials for more powerful and efficient batteries.
Early prototypes of quantum computers were brought online in the last decade. The performances of these forerunners invited skeptics to loudly claim that the industry would never reach the levels of performance that we have since come to see in the present.

Bioluminescent Tags Track RNA Dynamics in Live Cells in Real Time
A bioluminescent tag that can be attached to RNA will enable scientists to track RNA in real time as it moves through the human body.
To understand the central role of RNA in cellular processes, scientists must be able to track RNA in vivo. The new platform will allow scientists to observe the dynamics of RNA in numerous biological processes, from virus propagation to memory formation, in real time.
The bioluminescent RNA tag was developed by researchers at the University of California, Irvine. The researchers used luciferase, the enzyme that induces bioluminescence in fireflies, glowworms, jellyfish, and other organisms to make the tags. They engineered the RNA tags to recruit light-emitting luciferase fragments, called RNA...
