Therapy-induced senescent (TIS) cells are cancer cells that become resistant to therapies and enter a dormant stage. These cells can emerge from dormancy and induce tumor resistance and relapse. To provide insight into how TIS cells evolve, it is crucial to develop simple, reproducible methods to study the onset and progression of these cells in human cancer cell cultures.

An international team from Johns Hopkins University and Italy’s Politecnico di Milano, Fondazione Istituto Nazionale dei Tumori, and Consiglio Nazionale delle Ricerche developed a noninvasive, multimodal imaging technique to allow early identification of TIS cells. The new technique could improve clinical outcomes by enabling more comprehensive research into...]]>

OLEDs Could Be Solution to Electrically Driven, Organic Semi Lasers
The researchers used indirect OLED pumping to power the laser. They built an integrated device structure that efficiently coupled an OLED that had very high light output with a polymer-based, distributed feedback laser.

Most organic semiconductor lasers are optically pumped by another laser — a complicated, expensive process. Electrical pumping, which involves injecting a current to generate a population inversion, is challenging to achieve in organic...]]>

THz Generation Technique Could Transform Field of Ultrafast Electronics
Terahertz (THz) waves can be used to probe the magnetic properties of new materials. Efficient THz wave generation could advance applications in energy harvesting, ultrafast electronics, and THz spectroscopy.

Bright, coherent THz light sources can be achieved via high-frequency, high-density charge currents. It is possible to produce strong current density that is several orders of magnitude higher than what is typically found in electronic devices, by exciting nanometer-scale, metallic interfaces with femtosecond laser pulses.

To harness the power of high-density charge currents for generating THz waves, researchers at Fudan University, Shanghai Research Center for Quantum Sciences, and Beijing Normal University developed an...]]>

Wearable Sensor Could Lower Mortality Due to Postpartum Blood Loss
Postpartum hemorrhage, the leading and most preventable cause of maternal mortality, can be hard to detect, because physiological compensation mechanisms can mask excessive bleeding. In the early stages of hemorrhage, the sympathetic nervous system becomes activated to ensure adequate perfusion of vital organs and, in turn, vital signs remain stable.

Worldwide, the most common methods of diagnosing postpartum hemorrhage are visual estimation of blood loss or monitoring of vital signs. Blood loss is routinely underestimated beyond the point of early intervention.

To diagnose postpartum hemorrhage in its early stages, a multidisciplinary research team at Washington University in St. Louis developed a wearable optical device that...]]>

Photonic-Electronic NIC Serves Live Machine Learning Inference Requests
A burgeoning growth in machine learning applications is occurring alongside shrinking computing resources. As computers approach the limits of their power according to Moore’s law, the need to design platforms that support the computational demands of machine learning applications intensifies.

Lightning, a hybrid computing platform developed by an MIT research team, is the first photonic computing system to serve machine learning inference requests in real time. Lightning is a reconfigurable, photonic-electronic, smart network interface card (smartNIC) that is both fast and energy-efficient.

Unlike their electronic counterparts, photonic computing devices lack the memory or instructions to control dataflows. Lightning...]]>

Using LCDs to Create a More Comfortable, Immersive VR Experience
Researchers from Innolux Corp. have developed a 3.1-in. light-field liquid crystal display (LCD) featuring an ultrahigh pixel density to overcome limitations in near-eye display, such as light-field resolution issues. Light-field technology could also have applications beyond VR displays, such as in vision correction for VR systems.

Near-eye displays are vital to portable devices, providing individuals with immersive virtual reality experiences. The primary objectives in developing these displays are to create immersive experiences and ensure visual comfort. While a larger field of view (FOV) enhances immersion in virtual reality, addressing the vergence-accommodation conflict (VAC), a phenomenon that occurs when one’s eyes...]]>

Single-Layer OLED Design Offers Efficiency Without Complexity
With the development of a single-layer, blue-emitting OLED, researchers at the Max Planck Institute (MPI) for Polymer Research demonstrated that one-layer OLEDs can achieve a performance level comparable to commercial OLEDs with multiple layers, while simplifying OLED design, fabrication, and analysis.

Early OLEDs had a simple device structure. A semiconducting layer was sandwiched between two electrodes. Holes were injected into the organic semiconductor layer via the anode, and electrons via the cathode. Since then, considerable efficiency gains have been made by increasing the number of functional layers in OLEDs.

However, multilayer OLEDs are complex to design and fabricate. The need for additional fabrication steps can...]]>

More Efficient Microcombs on Road to Commercialization
Researchers at Chalmers University have developed a method to make microcombs 10 times more efficient, opening pathways to discovery in space and health care, and paving the way for high-performance lasers in a range of technologies. The team has established a company to commercialize the new technology.

Laser frequency combs can measure frequency with extreme levels of precision, analogous to a ruler made of light. The principle is based on a laser sending photons that circulate within a small cavity — a so-called microresonator — where the light is divided into a wide range of frequencies. These frequencies are precisely positioned in relation to each other, like the markings on a ruler. Therefore, a new kind of light...]]>

Single-Cell Analysis Fluidics Tool Delivers on Demand
An on-demand optical system for exporting target droplets from a static droplet array (SDA) provides a simple way to export specific cells or analytes for analysis without compromising efficiency or accuracy. Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology of the Chinese Academy of Sciences developed the system, called optical on-demand droplet release (OODR). The developers and their collaborators believe that OODR could promote SDAs as a valuable tool for use with high-capacity screening assays with applications in diverse fields. They said that the technique in its current stage of development has the potential to be used in single-molecule/cell analysis, drug screening, and phenotype-based cell sorting.
