This summer, Yishu Wang was awarded a $719,000 research grant from the United States Department of Energy (DOE) to study the dynamic and microscopic behaviors of magnets with quantum mechanical properties. Magnetism originates from electrons in a material. When the electrons in a material all spin in the same direction, as they do in metals like iron, the material is magnetic, with poles that attract or repel other magnetic materials. “Magnets that we are using today can be viewed as static orderings of electrons, analogous to the static pattern of brushstrokes in a painting,” said Wang, a joint assistant professor in the Department of Materials Science and Engineering ...

Terahertz communications represent the next frontier in wireless technology, promising data transmission rates far exceeding current systems. By operating at terahertz frequencies, these systems can support unprecedented bandwidth, enabling ultra-fast wireless communication and data transfer. However, one of the significant challenges in terahertz communications is effectively managing and utilising the available spectrum. The team has developed the first integrated terahertz polarisation (de)multiplexer implemented on a substrateless silicon base which they have successfully tested in the sub-terahertz J-band (220-330 GHz) for 6G communications and beyond. The University of Adelaide’s ...

Studies have shown that undergraduate students who participate in research activities under the guidance of a faculty mentor are more likely to finish college. That’s one of the many reasons universities like The University of Texas at Arlington are increasing their investment into undergraduate research.

An ancient gene is crucial for the development of the distinctive waist that divides the spider body plan in two, according to a study publishing August 29th in the open-access journal PLOS Biology by Emily Setton from the University of Wisconsin-Madison, US, and colleagues. The spider body is divided into two sections, separated by a narrow waist. Compared to insects and crustaceans, relatively little is known about embryonic development in spiders, and the genes involved in the formation of the spider waist are poorly understood. To investigate, researchers sequenced genes expressed in embryos of the Texas brown tarantula (Aphonopelma hentzi) ...

A new study paves the way to understanding biotic recovery after an ecological crisis in the Mediterranean Sea about 5.5 million years ago. An international team led by Konstantina Agiadi from the University of Vienna has now been able to quantify how marine biota was impacted by the salinization of the Mediterranean: Only 11 percent of the endemic species survived the crisis, and the biodiversity did not recover for at least another 1.7 million years. The study was just published in the renowned journal Science. Lithospheric movements throughout Earth history have repeatedly led to the isolation of regional seas from the ...

Staphylococcus aureus has the potential to develop durable vancomycin resistance, according to a study published August 28, 2024, in the open-access journal PLOS Pathogens by Samuel Blechman and Erik Wright from the University of Pittsburgh, USA. Despite decades of widespread treatment with the antibiotic vancomycin, vancomycin resistance among the bacterium S. aureus is extremely uncommon—only 16 such cases have reported in the U.S. to date. Vancomycin resistance mutations enable bacteria to grow in the presence of vancomycin, but they do so at a cost. Vancomycin-resistant S. aureus (VRSA) strains grow more slowly and will often lose their resistance mutations if vancomycin ...

A person’s exhaled breath – which provides information that could unveil diverse health insights – has been hard to analyze. Now, a novel “smart mask” provides real-time, non-invasive monitoring of what people exhale. The mask, dubbed EBCare, captures and analyzes exhaled breath condensate (EBC), and it offers a promising solution for continuous EBC analysis at an affordable cost. “The significance of EBCare lies in its role as a versatile, convenient, efficient, real-time research platform and solution in various medical domains, ...

Challenging long-held beliefs that bird nest building is solely influenced by genetics or the environment, researchers report that the white-browed sparrow weavers of the Kalahari Desert, Africa, build nests with distinct architectural styles that reflect group-specific cultural traditions. “Behavioral traditions in birds have been well documented for song, migration, foraging, and tool use. Here, we add building behavior and show that architectural styles emerge from birds that build together,” write the ...

Reactive oxygen species (ROS) from mitochondria are key drivers of genetic chaos in cancer by causing the collapse of micronuclear envelopes, a process that fuels the chromosomal instability (CIN) often observed in aggressive tumor behavior. These are the findings of two new studies. The findings identify key proteins in this destructive process – p62 and CHMP7 – revealing potential prognostic markers and therapeutic targets for high-CIN tumors. Errors in chromosome segregation during cell division can lead to chromosomal instability, a key feature of cancer. These errors result in the formation of micronuclei, which are small structures ...

A meta-analysis of Mediterranean Sea marine species reveals the profound impact of the Messinian Salinity Crisis – a drastic environmental event that resulted in the almost complete evaporation of the Mediterranean Sea roughly 5.5 million years ago. According to the new study’s findings, the event nearly reset the region’s biodiversity. The findings offer novel insights linking tectonic and palaeoceanographic changes to marine biodiversity, highlighting the significant role of salt giants in shaping biogeographic patterns, including those that still influence ecosystems today. The Messinian Salinity Crisis (MSC), ...

New study from Hebrew University reveals that marmoset monkeys use specific calls, known as "phee-calls," to name each other, a behavior previously known to exist only in humans, dolphins, and elephants.
