FBH at Photonics Days 2024. On October 9 and 10, 2024, the Ferdinand-Braun-Institut will contribute to the Photonics Days Berlin Brandenburg with lectures and the accompanying exhibition. For two days, experts from research and industry will meet in Berlin Adlershof to discuss current trends in laser technology, heterointegration, microsystems technology, and various other topics. A key focus on October 9 and 10 will be on quantum technologies. Prof. Tim Schröder, who heads the Joint Lab Diamond Nanophotonics at Ferdinand-Braun-Institut (FBH)…
New brain organoid model replicates human cortical domains. Brain organoids provide unique insights into the human brain. Now, the group of Jürgen Knoblich at the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences, developed a new method that allows scientists to cultivate brain organoids with distinct cortical areas and front-to-back patterning. Together with collaborators at the Human Technopole and the University of Milan-Bicocca, they reported a method that gives scientists a deeper look into human-specific brain development…
By controlling silk protein nanostructure for the first time, scientists at PNNL pave the way for advanced microelectronic and computing applications. After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing. While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands. Now, a research team led by…
After an unexpected measurement by the Collider Detector at Fermilab (CDF) experiment in 2022, physicists on the Compact Muon Solenoid experiment (CMS) at the Large Hadron Collider (LHC) announced today a new mass measurement of the W boson, one of nature’s force-carrying particles. This new measurement, which is a first for the CMS experiment, uses a new technique that makes it the most elaborate investigation of the W boson’s mass to date. Following nearly a decade of analysis, CMS has found…
The spacecraft bus that will deliver NASA’s Nancy Grace Roman Space Telescope to its orbit and enable it to function once there is now complete after years of construction, installation, and testing. Now that the spacecraft is assembled, engineers will begin working to integrate the observatory’s other major components, including the science instruments and the telescope itself. “They call it a spacecraft bus for a reason — it gets the telescope to where it needs to be in space,” said…
The AQT quantum computer, featuring 20 qubits based on trapped-ion technology, is now operational at LRZ’s Quantum Integration Centre (QIC), making it the first of its kind in a computing center. The system supports both MQV’s quantum software development efforts and selected research groups from Munich Quantum Valley (MQV) accessing the system during a pilot phase starting in October. The system was purchased by MQV and funded by the Free State of Bavaria with around 9.8 million Euros as part…
Theorists turn to supercomputers to help build a 3D picture of the structures of protons and neutrons. Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom’s nucleus — particles called hadrons that a high school student would recognize as protons and neutrons — are made up of a seething mixture of interacting quarks and gluons, known collectively as partons. A group of physicists has now come…
Retrons raise the bar for gene research. Gladstone scientists undertake a major effort to examine the diversity of retrons, bacterial defense systems that can be leveraged for precise gene editing. Within bacterial cells, specialized immune systems known as retrons fend off viral attacks. But that’s not all they can do. Scientists, including Seth Shipman, PhD, at Gladstone Institutes, have shown that retrons also serve an important purpose in the lab: precise DNA editing. In fact, retrons can be combined with…
TU Wien (Vienna) has succeeded in generating laser-synchronised ion pulses with a duration of well under 500 picoseconds, which can be used to observe chemical processes on material surfaces. If you want to photograph something very fast, you need a camera with a very short exposure time. The same principle applies everywhere in physics: for example, extremely short laser pulses are used to visualise the processes that take place within atoms. However, it is not only laser pulses that provide…
Plan will advance knowledge of virus biology to improve detection, treatment and prevention. As part of the U.S. government response to the current mpox outbreak, the National Institutes of Health’s (NIH) National Institute of Allergy and Infectious Diseases (NIAID) has released an update on its priorities for mpox research. The NIAID mpox research agenda focuses on four key objectives: increasing knowledge about the biology of all clades—also known as strains—of the virus that causes mpox, including how the virus is…
New model of the skin microbiome allows laboratory testing in realistic conditions Impact of cosmetic ingredients on microbial communities is now measurable Scientifically substantiated efficacy claims are growth drivers for the cosmetics industry Evonik has developed a new model of the skin microbiome. For the first time, this model allows a scientifically substantiated evaluation of the influence of cosmetic ingredients and products on skin microbiota in laboratory tests. The company is currently testing cosmetic ingredients from its own product portfolio…
A different qubit architecture could enable easier manufacturing of quantum computer building blocks without compromising performance. Scientists from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have shown that a type of qubit whose architecture is more amenable to mass production can perform comparably to qubits currently dominating the field. With a series of mathematical analyses, the scientists have provided a roadmap for simpler qubit fabrication that enables robust and reliable manufacturing of these quantum computer building blocks. This…
Researchers from the Cluster of Excellence ct.qmat have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world. Gravity is no longer a mystery to physicists – at least when it comes to large distances: thanks to science, we can calculate the orbits of planets, predict tides, and send rockets into space with precision. However, the theoretical description of gravity reaches its limits at the…
Columbia Engineers develop new powerful battery “fuel” — an electrolyte that not only lasts longer but is also cheaper to produce. Renewable energy sources like wind and solar are critical to sustaining our planet, but they come with a big challenge: they don’t always generate power when it’s needed. To make the most of them, we need efficient and affordable ways to store the energy they produce, so we have power even when the wind isn’t blowing or the sun…
Going beyond fertility, treatment also fixes hormone production and overall health. Medication to reduce ovarian scarring helps extends overall health of reproductive system Freezing eggs only addresses age-related infertility, not ovarian hormone loss. New treatment would ‘fix the root of the issue’ Findings also have implications for developing treatments for ovarian cancer A woman’s ovaries are like a factory where eggs grow and produce hormones that regulate everything from menstruation and pregnancy to bone density and mood. As she and…
Researchers at the University of Bonn and the University of Cambridge have identified an important control circuit involved in the eating process. The study has revealed that fly larvae have special sensors, or receptors, in their esophagus that are triggered as soon as the animal swallows something. If the larva has swallowed food, they tell the brain to release serotonin. This messenger substance – which is often also referred to as the feel-good hormone – ensures that the larva continues…
