Recently, a research team achieved real-time tracking of electronic/magnetic structure evolution in Li-rich Mn-based materials during the initial cycling through the self-developed operando magnetism characterization device.

Their study, published in Advanced Materials, elucidated the critical mechanism underlying the oxygen reaction. The research team was led by Prof. Zhao Bangchuan from the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. Zhong Guohua from the Shenzhen Institute of Advanced Technology and Prof. Li Qiang from Qingdao University.

With the rise of electric vehicles and the low-altitude economy, the demand for high-energy-density batteries is growing. Li-rich Mn-based materials stand out due to their high capacity, wide voltage range, and .

Picture yourself at a busy pedestrian crossing. When the light is red, everyone waits—until one person starts to cross. Soon, others follow, and eventually everyone follows the crowd and crosses. Amsterdam physicists have discovered that a very similar process happens at the microscopic level, when two touching surfaces start to slide. Their results were published in Physical Review Letters this week.

In their experiment, Liang Peng, Thibault Roch, Daniel Bonn and Bart Weber pressed a smooth silicon surface against a rough one. The researchers, from the University of Amsterdam and the Advanced Research Center for Nanolithography, then explored how the friction behaved when the strength with which the two surfaces are pressed together was varied. Does it get harder to slide the two surfaces along one another when one presses harder? And, importantly: why?

“Our data shows that Oropouche virus is massively under-diagnosed in Latin America,” says Drexler, who also conducts research at the German Center for Infection Research (DZIF). “In some areas, at least one person in ten has experienced a prior infection with the pathogen.”

More widespread than thought – but still insufficiently investigated

Oropouche virus causes nonspecific symptoms such as fever, chills, headache, pain in the limbs, and, in some cases, nausea and skin rashes. For a long time, the disease was considered to be predominantly mild, and reports of more severe bouts, including meningitis, were rare.

Scientists at UC Berkeley have developed a new platform called “Oz” that can simultaneously control up to 1,000 photoreceptors in the eye, offering new insights into the mechanisms of human vision and the causes of vision loss. In Frank Baum’s original novel The Wonderful Wizard of Oz, the Emeral

This could also have a negative impact on research since patients with PSP may be misdiagnosed with Parkinson’s disease and be included in a trial that targets the wrong protein, influencing the results.

The research that led to the PSP breakthrough has roots in an earlier study. In previous research, Martinez-Valbuena and his colleagues developed a test that could detect misfolded alpha synuclein protein in the skin in patients with Parkinson’s.

Researchers have since validated that assay and hope it can be used in clinical trials, although the test is not yet available for clinical diagnoses.

Extract from “Evolution, Basal Cognition and Regenerative Medicine”, kindly contributed by Michael Levin in SEMF’s 2023 Interdisciplinary Summer School (https://semf.org.es/school2023/). Full talk: • Michael Levin | Evolution, Basal Cogn… TALK ABSTRACT Each of us has made the remarkable journey from a single cell (a quiescent oocyte) to a complex embodied mind. How do cells, which were once independent organisms, work together to pursue the anatomical and physiological goals that enable form and function to reliably self-assemble? In this talk, I will tell the story of the collective intelligence of cellular swarms that embodies William James’ definition of intelligence: same ends by different means. I will describe the amazing competencies of the morphogenetic process that builds bodies and minds, and our discoveries on bioelectricity — the cognitive glue that implements embryogenesis, regeneration, and cancer suppression. I will end with a perspective on how biophysical, informational, and behavioral sciences are coming together to redefine the boundaries of the possible in biomedicine and beyond.
