Materials with negative thermal expansion as electrodes for lithium-ion batteries. Image Credit: Angewandte ChemieMost solids expand as temperatures increase and shrink as they cool. Some materials do the opposite, expanding in the cold. Lithium titanium phosphate is one such substance and could provide a solution to the problem of steeply declining performance of lithium-ion batteries in cold environments. In the journal Angewandte Chemie, a Chinese team has demonstrated its suitability for use in electrodes for rechargeable batteries. Temperatures Pose a…
Jülich scientists use novel RNA technology to selectively switch off tumours in the brain. An Adaptable Platform Technology That Destroys Glioblastoma Cancer Cells Using novel RNA technology to selectively switch off tumors in the brain, excerpt from infographic. Copyright: Forschungszentrum Jülich / Bernd HoffmannUsing a special RNA molecule, a team led by Jülich scientists has specifically attacked and destroyed glioblastoma cancer cells. The so-called selectively expressed RNA (seRNA) causes the diseased cells to produce a protein that leads to their…
Can strength and endurance training be beneficial for patients with a certain form of heart failure? A research team from Greifswald investigated this question together with seven other research centers in Germany. In the largest study of its kind to date, the effect of one year of training on the health of patients was examined. The research team was able to prove that those affected benefited from better performance and resilience in everyday life. The results have now been published…
Overfishing, illegal fishing and increasing marketing of shark meat pose significant threats to the more than 80 species of sharks and rays that inhabit the Mediterranean Sea, according to a new study. Current Legislation for Elasmobranch Conservation The research examined current levels of legislation in place to protect elasmobranch populations (which include sharks, rays and skates) within each of the 22 coastal states of the Mediterranean region. Across those countries – stretching from Spain and Morocco in the west to…
Children and young people with high levels of mental health needs are struggling to receive the help they need, or to have their difficulties recognised, according to a new study. STADIA Decodes Young People’s Emotional Struggles The STADIA trial, which is published in the Journal of Child Psychology and Psychiatry, was led by experts from the School of Medicine at the University of Nottingham, and was funded by the National Institute for Health and Care Research (NIHR). The large study, which spans different parts…
Researchers from Osaka University introduced an innovative technology to lower power consumption for modern memory devices. Stepping up the Memory Game: Overcoming the Limitations of Traditional RAM Osaka, Japan – Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers several advantages over conventional RAM, including its non-volatility, high speed, increased storage capacity and enhanced endurance. Although…
Cutting-Edge Framework for Enhancing System Security Researchers at the University of Electro-Communications have developed a groundbreaking framework for improving system security by analyzing business process logs. This framework focuses on ensuring that role-based access control (RBAC) rules-critical to managing who can access specific system resources-are correctly implemented. Noncompliance with these rules, whether due to error or malicious activity, can result in unauthorized access and pose significant risks to organizations. Challenges in Ensuring Compliance with RBAC Policies RBAC is a widely…
Microorganisms are everywhere and have been influencing the Earth’s environment for over 3.5 billion years. Researchers from Germany, Austria and Taiwan have now deciphered the role they play in the formation of lime – for the first time in the deep sea rather than in the laboratory. The basis was a five-meter-long lime core obtained during an expedition. The team of authors has now published their results in the journal Communications Earth & Environment. Correlation between Microorganisms and Mineral Formation…
Analysis of three decades of aerial survey data reveals major changes In the Arctic, the old, multiyear ice is increasingly melting, dramatically reducing the frequency and size of pressure ridges. These ridges are created when ice floes press against each other and become stacked, and are a characteristic feature of Arctic sea ice, an obstacle for shipping, but also an essential component of the ecosystem. In a recently released study in the journal Nature Climate Change, experts from the Alfred Wegener…
Results of a comprehensive analysis refute assumptions that a key immune checkpoint receptor functions the same in rodents and humans The Discovery of PD-1: A Milestone in Cancer Treatment Since its discovery in the 1990s, “programmed cell death protein 1,” or PD-1, has been regarded as a leading target in cancer treatments. A “checkpoint” receptor that often resides on the surface of immune system cells, the PD-1 molecule works as a type of off switch that keeps immune cells from…
First large cohort study at the Heart and Diabetes Center NRW awarded – Hilke Jung presents research project at the FoRUM conference of the Ruhr University Bochum A working group led by Prof. Dr. Vera von Dossow, Director of the Institute for Anaesthesiology and Pain Therapy at the Heart and Diabetes Center NRW (HDZ NRW), Bad Oeynhausen, has now demonstrated for the first time in a large retrospective cohort study that longer and more frequent phases of intraoperatively low blood…
To stay healthy, plants balance the energy they put into growing with the amount they use to defend against harmful bacteria. The mechanisms behind this equilibrium have largely remained mysterious. Soil Bacteria: The Unexpected Key to Plant Immunity Now, engineers at Princeton have found an answer in an unexpected place: the harmless, or sometimes beneficial, bacteria that cluster around plants’ roots. In an article published Dec. 24 in the journal Cell Reports, researchers showed that some types of soil bacteria can influence a…
The longest natural metagenome time series ever collected, with microbes, reveals a startling evolutionary pattern on repeat. A Microbial “Groundhog Year” in Lake Mendota Like Bill Murray in the movie “Groundhog Day,” bacteria species in a Wisconsin lake are in a kind of endless loop that they can’t seem to shake. Except in this case, it’s more like Groundhog Year. According to a new study in Nature Microbiology, researchers found that through the course of a year, most individual species of bacteria in…
Achilles tendon injuries are common but challenging to monitor during recovery due to the limitations of current imaging techniques. Researchers, led by Associate Professor Zeng Nan from the International Graduate School at Shenzhen, Tsinghua University, have applied Mueller matrix polarimetry, a non-invasive imaging method, to more accurately observe and evaluate the healing of Achilles tendon injuries. This technique offers unique insights by capturing the subtle changes in tendon tissue without needing labels or dyes, allowing for more natural tissue characterization….
Researchers have come up with a new way to identify more infectious variants of viruses or bacteria that start spreading in humans – including those causing flu, COVID, whooping cough and tuberculosis. Real-Time Monitoring of Pathogens The new approach uses samples from infected humans to allow real-time monitoring of pathogens circulating in human populations, and enable vaccine-evading bugs to be quickly and automatically identified. This could inform the development of vaccines that are more effective in preventing disease. The approach…
Groundbreaking cerium oxide-based thermal switches achieve remarkable performance, transforming heat flow control with sustainable and efficient technology. Cerium Oxide-Based Thermal Switches Revolutionize Heat Flow Control Thermal switches, which electrically control heat transfer, are essential for the advancement of sophisticated thermal management systems.
