A new quantum sensor developed by researchers from Korea and Germany can measure magnetic fields at the atomic scale with high precision. This technology uses a single molecule for detection, offering superior resolution and the potential for significant advancements in quantum materials and molecular systems analysis.

In a scientific breakthrough, an international research team from Korea’s IBS Center for Quantum Nanoscience (QNS) and Germany’s Forschungszentrum Jülich developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.

Aging is associated with blood flow changes in the brain.

These changes may be linked to an increased risk of neurodegenerative conditions.

Researchers have mapped the aging processes of blood vessels in the brains of mice in an effort to establish how they affect cognitive decline.

The effective integration of extremely thin insulating layers with two-dimensional (2D) semiconductors could enable the fabrication of 2D transistors with an electrical capacitance comparable to SiO₂ with thicknesses below 1-nm. These transistors could, in turn, help to boost the performance and reduce the power consumption of electronic devices.

Researchers at Nankai University in China recently introduced a new strategy to synthesize single-crystalline metal nanosheets that could be easily transferred onto 2D substrates. This strategy, outlined in a paper in Nature Electronics, was successfully used to deposit 2-nm-thick dielectrics based on Al₂O₃ or HfO₂ for highly performing top-gated transistors.

“At the very beginning, we aimed to developing the chemical vapor deposition (CVD) synthetic strategy of 2D Cu₂O, which is a p-type high-mobility 2D semiconductor,” Jinxiong Wu, corresponding author of the paper, told Tech Xplore.

We occasionally see animals that don’t look like they belong in the 21st century. Here are seven prehistoric-looking creatures that stand out more than most.

ACE, a groundbreaking DNA-powered signal amplification technology, significantly enhances the sensitivity of mass cytometry, providing new insights into various biological and pathological processes.

Since the 1950s, researchers have employed “flow cytometry,” a renowned technique devised by Wallace Coulter, to characterize various types of immune cells in research studies and human blood samples. This method has significantly enhanced our understanding of immune cell development and provided innovative approaches for evaluating human health and diagnosing various blood cancers. Eventually, flow cytometry was extended to analyze other cell types as well.

In traditional flow cytometry, cell surface and intracellular proteins are detected with antibody molecules that are linked to fluorescent probes. However, while providing single-cell sensitivity, this method is limited in detecting multiple proteins by the number of fluorophores that can be clearly distinguished within the entire spectrum of fluorescent light.

Summary: Researchers developed a computer model that mimics how the hippocampus stores new episodic memories without erasing old ones. This model demonstrates that the CA3 region of the hippocampus serves as an anchor point for memories, allowing efficient storage in surrounding regions.

The findings reveal insights into how the brain organizes personal experiences and maintains stability despite constant updates. The model shows promise for enhancing our understanding of memory retention and cognitive processing.
