Researchers from Austria and USA have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team led by Peter Zoller demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics. Fermionic atoms are atoms that obey the Pauli exclusion principle, which means that no…
Researchers from Japan and Vietnam develop a new approach that utilizes fuzzy logic to estimate unknown parameters and control nonlinear pneumatic artificial muscles. In recent years, pneumatic artificial muscles (PAMs) have emerged as promising actuators for simulating human-like movements, with prominent applications in various industries including robotics, rehabilitation, and prosthetics. PAMs are usually composed of rubber and covered with braided yarn and can mimic the mechanics of human muscles. They can stiffen and contract on being supplied with pressurized air…

Already creating a buzz, the platform is now collecting data and generating…
Coral reefs in one part of the Pacific Ocean have likely adjusted to higher ocean temperatures which could reduce future bleaching impacts of climate change, new research reveals. A Newcastle University-led study focused on the Pacific Island nation of Palau and has shown that historic increases in the thermal tolerance of coral reefs are possible. The results demonstrate how this capacity could reduce future bleaching impacts if global carbon emissions are cut down. Drawing on decades of field observations, the…
Airborne computing platform would improve drone communication. A University of Texas at Arlington researcher is constructing an open-networked airborne computing platform to enable unmanned aerial vehicles (UAVs) to help first responders better coordinate their efforts during emergency or disaster responses. UT Arlington also is developing a universal plug-in hardware unit that can fit into any UAV to allow for this computing platform to be used. The National Science Foundation (NSF) is funding the research through a $1.8 million grant to…
A new theory shows how water underneath glaciers may surge — creating a dangerous feedback cycle. Two Georgia Tech researchers, Alex Robel and Shi Joyce Sim, have collaborated on a new model for how water moves under glaciers. The new theory shows that up to twice the amount of subglacial water that was originally predicted might be draining into the ocean – potentially increasing glacial melt, sea level rise, and biological disturbances. Shi Joyce Sim is a research scientist…
Using the Fraunhofer Versatile Video Decoder (VVdeC), Electronic Team, Inc. has introduced H.266/VVC Codec support to its popular Elmedia Player. The free media player for macOS is the first to natively support the playback of video encoded with the most recent and most efficient video coding standard Versatile Video Coding (VVC). VVdeC was developed at the “Video Communication and Applications” department of Fraunhofer Heinrich-Hertz-Institut (HHI). Fraunhofer HHI and Electronic Team, Inc. successfully collaborated to implement native support for the H.266/VVC…
Mice on a time-restricted feeding schedule had better memory and less accumulation of amyloid proteins in the brain compared to controls. One of the hallmarks of Alzheimer’s disease is disruption to the body’s circadian rhythm, the internal biological clock that regulates many of our physiological processes. Nearly 80% of people with Alzheimer’s experience these issues, including difficulty sleeping and worsening cognitive function at night. However, there are no existing treatments for Alzheimer’s that target this aspect of the disease. A…
Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers at DZNE come to this conclusion on the basis of studies on cell cultures. They report on this in the journal “Nature Communications”. In their view, such “endogenous retroviruses” could contribute to the spread of aberrant protein aggregates – hallmarks of certain dementias – in the brain. Thus, these viral relicts would be potential targets for therapies. It has been…
SARS-CoV-2 viruses manage to hijack human cells with a minimum of their own proteins and use them as incubators for their offspring. One of these multifunctional viral proteins is the nucleocapsid protein (N), which plays a key role in viral replication and packaging. Researchers from Goethe University Frankfurt have now discovered how N recognizes both viral RNA in general as well as specific RNA positions with the help of “fingers”. In the latter, N adapts to the increased temperature of…
The dynamic interplay where high-performance computing meets biophysical exploration, pushing the frontiers of knowledge and catalyzing a new era of unprecedented discoveries in biology. In a recently published article featured on the cover of the Biophysical Journal, Dr. Rafael Bernardi, assistant professor of biophysics at the Department of Physics at Auburn University, and Dr. Marcelo Melo, a postdoctoral researcher in Dr. Bernardi’s group, shed light on the transformative capabilities of the next generation of supercomputers in reshaping the landscape of…
Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure. Alloys, a combination of two or more types of metals, are used in many applications, like turbines for jet engines and light-weight alloys for automotive applications, because they have very good mechanical properties due to those embedded precipitates. The average precipitate size, however, tends to increase over…
The process could usher in an era of shot-free vaccines, researchers say. Rutgers scientists have devised a highly accurate method for creating coatings of biologically active materials for a variety of medical products. Such a technique could pave the way for a new era of transdermal medication, including shot-free vaccinations, the researchers said. Writing in Nature Communications, researchers described a new approach to electrospray deposition, an industrial spray-coating process. Essentially, Rutgers scientists developed a way to better control the target…
How a supposed “nuclear” receptor makes TCR signaling possible. According to new research in the journal Immunity, T cells have a nuclear receptor doing something very odd—but very important—to help them fight pathogens and destroy cancer cells. This receptor, called retinoic acid receptor alpha (RARα), is known to control gene expression programs in the nucleus, but it also now appears to operate outside the cell nucleus to coordinate the early events triggered at the cell surface that lead to T cell…

Cultivated autologous limbal epithelial cells (CALEC) procedure shown to be safe and feasible with early positive results of restored cornea surfaces or vision gains in four patients with severe chemical burns. A team led by researchers from Mass Eye and Ear, a member of Mass General Brigham, reports the results of a phase I trial of a revolutionary stem cell treatment called cultivated autologous limbal epithelial cell transplantation (CALEC), which was found to…
