After having to take a pandemic break of four years, the industrial laser technology community met at “AKL’22 – International Laser Technology Congress” in Aachen from May 4 to 6, 2022. The industry is doing well, and the biggest trend is the extensive digitalization of processes. At the same time, common beam sources are being pushed to ever new levels of peak performance. New to the conference program was the Quantum Technology & Photonics Forum, where major German companies presented…
Organoids that mimic human brain cortex in development and disease: “Outer Radial Glia” (oRG) cells are nervous system stem cells that are instrumental for the development of the human cortex and have been challenging to produce in the lab. Now, a team of Max Planck researchers from Berlin succeeded in generating brain organoids that are enriched with these stem cells by refining and standardizing existing protocols for these mini-organs. Organoids are advanced three-dimensional cell cultures that form miniature versions of…
New research introduces self-powered smart implants to monitor spinal fusion healing. Spinal fusion—fusing two vertebrae together—can treat a wide variety of spinal disorders. Often, surgeons will use a cage to provide support where the disk once was between the vertebrae. But what if those cages could support the spine’s healing in more ways than one? Researchers at the University of Pittsburgh Swanson School of Engineering are creating patient-specific 3D-printed smart metamaterial implants that double as sensors to monitor spinal healing….
Reading between the lines to model our galaxy’s central black hole. Looks can be deceiving. The light from an incandescent bulb seems steady, but it flickers 120 times per second. Because the brain only perceives an average of the information it receives, this flickering is blurred and the perception of constant illumination is a mere illusion. While light cannot escape a black hole, the bright glow of rapidly orbiting gas (recall the images of M87’s black hole and Sgr A*)…
The oceans are teeming with countless forms of life, from the world’s largest creature – the blue whale – to miniscule microorganisms. In addition to their vast numbers, these microorganisms are also crucial for ensuring that the entire eco- and climate system work properly. For instance, there are photosynthetically active varieties such as cyanobacteria that produce around 50 percent of the oxygen in the atmosphere. Moreover, by removing carbon dioxide from the atmosphere, microorganisms help counter global warming. Despite this…
The first report of room temperature ferroelectricity in bulk hafnia could extend Moore’s Law for data storage. The Science Ferroelectric materials are substances with spontaneous electrical polarization. Polarization refers to the separation of the negative and positive charges within a material. For ferroelectric materials, this means the “memory” of the material’s prior state (referred to as hysteresis) can store information in a way similar to magnetic storage devices such as hard disks. Ferroelectric materials based on the element hafnium show…
Rice lab draws on nature to create flexible precursors for drug and materials design. Inspired by your liver and activated by light, a chemical process developed in labs at Rice University and in China shows promise for drug design and the development of unique materials. Researchers led by Rice chemist Julian West and Xi-Sheng Wang at the University of Science and Technology of China, Hefei, are reporting their successful catalytic process to simultaneously add two distinct functional groups to single alkenes, organic molecules drawn…

Stem cells and progenitor cells play an important role in the renewal of multiple tissues. Professor Jyrki Heino’s research group from the University of Turku together and Professor Fiona Watt´s research group from King’s College London have discovered a molecule called embigin on the surface of epithelia progenitor cells and proven its significance to sebaceous gland function. In biochemical experiments conducted at the University of Turku, researchers were able to demonstrate that embigin binds to the extracellular matrix protein called…
An international team of researchers has demonstrated a technique that allows them to align gold nanorods using magnetic fields, while preserving the underlying optical properties of the gold nanorods. “Gold nanorods are of interest because they can absorb and scatter specific wavelengths of light, making them attractive for use in applications such as biomedical imaging, sensors, and other technologies,” says Joe Tracy, corresponding author of a paper on the work and a professor of materials science and engineering at North…
Researchers develop an olfactory sensor for biometric authentication using your breath. Biometric authentication like fingerprint and iris scans are a staple of any spy movie, and trying to circumvent those security measures is often a core plot point. But these days the technology is not limited to spies, as fingerprint verification and facial recognition are now common features on many of our phones. Now, researchers have developed a new potential odorous option for the biometric security toolkit: your breath. In…
The rhizosphere-on-a-chip offers an easier way to study a plant’s influence underground. The Science The rhizosphere is the living ecosystem around plant roots. It is a dynamic ecosystem of plant and microbes that is difficult to study because soil is opaque and complex. By creating a synthetic rhizosphere in the lab, scientists can study underground interactions in a simulated habitat that is less complex but that retains key characteristics of the natural ecosystem. Scientists have developed a rhizosphere-on-a-chip with a…

In a research work published June 19 in Journal of the American Chemical Society reported an innovative study that a group of scientists who have been engaged in Surface-enhanced Raman spectroscopy (SERS), made a nano-ruler to look deeply into longitudinal plasmonic field in a nanocavity. SERS is a highly sensitive and powerful spectral analysis technique applicable in various fields. In contrast to weak Raman scattering, SERS realized a dramatically enhanced Raman…
… using a 3D computational simulation. A team of researchers at Nagoya University in Japan has created a 3-Dimensional computational simulation of the process of genome structure formation in the human cell nucleus. They expect the model to contribute to the understanding of cellular regulatory mechanisms and diseases, such as cancer, that damage the genome. The three-dimensional structure of the genome plays a vital role in regulating the DNA functions of animal and plant cells because it affects its reading…
Osaka Metropolitan University researchers observed unprecedented collective resonance motion in chiral helimagnets that allow a boost in current frequency bands. When will 6G be a reality? The race to realize sixth generation (6G) wireless communication systems requires the development of suitable magnetic materials. Scientists from Osaka Metropolitan University and their colleagues detected an unprecedented collective resonance at high frequencies in a magnetic superstructure called a chiral spin soliton lattice (CSL), revealing CSL-hosting chiral helimagnets as a promising material for 6G…
