Tissue processing advance can label proteins at the level of individual cells across whole, intact rodent brains and other large samples just as fast and uniformly as in dissociated single cells.

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team from the University of Innsbruck, together with a team from RWTH Aachen and Forschungszentrum Jülich, has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform all computing operations protected against errors.

A new study by researchers at the Department of Molecular Medicine at SDU sheds light on one of the most severe consequences of stroke: damage to the brain's "cables"—the so-called nerve fibers—which leads to permanent impairments. The study, which is based on unique tissue samples from Denmark's Brain Bank located at SDU, may pave the way for new treatments that help the brain repair itself.

A research team led by Associate Professor Ding PAN from the Department of Physics and the Department of Chemistry at the Hong Kong University of Science and Technology (HKUST), in collaboration with Prof. Yuan Yao from the Department of Mathematics, has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO₂) in supercritical water. These findings are crucial for understanding the molecular mechanisms of CO₂ mineralization and sequestration in nature and engineering, as well as the deep carbon cycle within the Earth's interior. This understanding will help pave the way for new directions in future carbon sequestration technologies. The study was published in the Proceedings of the National Academy of Sciences (PNAS)*.

A new theory predicts one of the effects of macroscopic mechanical forces on mechanochemical organic synthesis by a ball mill.

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap between the valence and conduction bands, allowing them to handle higher voltages, operate at higher frequencies, and provide greater efficiency compared to traditional materials like silicon. However, their unique properties make it challenging to probe and understand how charge and heat move on nanometer-to-micron scales. Visible light has a very limited ability to probe nanoscale properties, and moreover, it is not absorbed by diamond, so it cannot be used to launch currents or rapid heating.

Now, researchers at JILA, led by JILA Fellows and University of Colorado physics professors Margaret Murnane and Henry Kapteyn, along with graduate students Emma Nelson, Theodore Culman, Brendan McBennett, and former JILA postdoctoral researchers Albert Beardo and Joshua Knobloch, have developed a novel microscope that makes examining these materials possible on an unprecedented scale. The team’s work, recently published in Physical Review Applied, introduces a tabletop deep-ultraviolet (DUV) laser that can excite and probe nanoscale transport behaviors in materials such as diamond. This microscope uses high-energy DUV laser light to create a nanoscale interference pattern on a material’s surface, heating it in a controlled, periodic pattern. Observing how this pattern fades over time provides insights into the electronic, thermal, and mechanical properties at spatial resolutions as fine as 287 nanometers, well below the wavelength of visible light. 

Chirality is a fundamental property of matter that determines many biological, chemical and physical phenomena. Chiral solids, for example, offer exciting opportunities for catalysis, sensing and optical devices by enabling unique interactions with chiral molecules and polarized light. These properties are however established when the material is grown, that is, the left- and right-handed enantiomers cannot be converted into one another without melting and recrystallization. Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) and the University of Oxford have shown that terahertz light can induce chirality in a non-chiral crystal, allowing either left- or right-handed enantiomers to emerge on demand. The finding, reported in Science, opens up exciting possibilities for exploring novel non-equilibrium phenomena in complex materials.
