It's common to wonder as tax season ramps up: Are taxes too high? According to a new study by University of Cincinnati economics professor David Brasington, the answer is no, at least when it comes to Ohio's city service taxes. These taxes go toward local services such as funds for the fire department, road repair and park upkeep.
Researchers are continually looking for new ways to hack the cellular machinery of microbes like yeast and bacteria to make products that are useful for humans and society. In a new proof-of-concept study, a team from the Carl R. Woese Institute for Genomic Biology showed they can expand the biosynthetic capabilities of these microbes by using light to help access new types of chemical transformations.
A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand operation with record-high photon quality in the telecommunications C-band—a key step toward scalable photonic quantum computation and quantum communication. "The lack of a high-quality on-demand C-band photon source has been a major problem in quantum optics laboratories for over a decade—our new technology now removes this obstacle," says Prof. Stefanie Barz.
When waves are moving across ice-covered seas, they can cause sheets of ice to bend and ultimately break. Understanding the processes underlying these wave-induced ice fractures and predicting when they will occur could help to better forecast how climate change will impact the environment and marine ecosystems on Earth.
Researchers led by Yasunori Ichihashi at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan recently examined how different kinds of pesticides and fertilizers affect mandarin oranges across Japan. Their study, published in Plant Biotechnology, involving advanced statistical analysis, showed that while reducing pesticides enhanced the diversity of microbes in the soil, it also led to an increase in fruit disease caused by leaf pathogens.
NASA has delayed astronauts' upcoming trip to the moon because of near-freezing temperatures expected at the launch site.
The precise control of tiny droplets on surfaces is essential for advanced manufacturing, pharmaceuticals, and next‐generation lab‐on‐a‐chip diagnostics. However, once droplet volume reaches pico- and nanoliter scales, the droplets become extremely sensitive to microscopic surface irregularities, and friction at the solid‐liquid interface becomes a major obstacle to smooth transport.
Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeeded for the first time in performing optical measurements with atomic resolution. Their work is published in the journal Nano Letters.
The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control hub, according to a study by researchers at Science Tokyo. Deleting a single amino acid in this region transforms a full-length antibody into a stable half-IgG1 molecule with altered immune activity.
Cells operate on rules not vibes, including when on the precipice of persisting or perishing. Yet, with prior research methods, scientists studying this phenomenon had to infer how cells choose to sustain themselves or self-destruct based on the output of their protein factories. While much more advanced than a pundit's vibe check, these analyses were constrained by the inability to account for the activity of these proteins after their construction.
