Identifying a topological fingerprint

HARWELL, UK (29 June 2021) Researchers working on the Faraday Institution project on the recycling of lithium-ion batteries (ReLiB) at the Universities of Leicester and Birmingham have solved a critical challenge in the recovery of materials used in electric vehicle batteries at the end of their life, enabling their re-use in the manufacture of new batteries. The new method, which uses ultrasonic waves to separate out valuable material from the electrodes, is 100 times quicker, greener and leads to a higher purity of recovered materials relative to current separation methods. The research has been published in Green Chemistry and the team have applied for a patent for the technique. To ...

Patients with mild Covid-19 infections experience a significantly increased longer lasting reduced sense of taste and smell. This is also the case for long-term shortness of breath, although relatively few people are affected. And women and the elderly are particularly affected. This is shown by new research findings from Aarhus University Aarhus University Hospital and Regional Hospital West Jutland The last 14 months have taught us that there are different symptoms and outcomes of Covid-19. However, the vast majority of people who fall ill with Covid-19 experience mild symptoms and get over ...

Attention Deficit Hyperactivity Disorder (ADHD) affects about 7% of children, with a two out of three chance of persisting into adulthood. This neurodevelopmental disorder is characterised by concentration difficulties, increased distractibility, impulsivity and hyperactivity. Today, ADHD is treated with pharmaceutical drugs that may have unwanted side effects. This is why scientists from the University of Geneva (UNIGE) and the University Hospitals of Geneva (HUG), Switzerland, explored a new technique called 'neurofeedback', which enables ADHD patients to train their attention, based on instant feedback from the level of their brain activity. The team of neuroscientists found that not only did the training have a positive effect on patients' concentration abilities, but also that the ...

An international team of researchers has identified a novel mechanism in barley plants, which could help crop growers achieve high yields as temperatures rise. With grain production highly sensitive to changing environmental conditions, rising temperatures are known to reduce the number of seeds that can be produced on each plant. One solution is to increase the number of flowers or branches on each 'spike', which is the reproductive structure from which grain is harvested. In a study published in Nature Plants, research led by Professor Dabing Zhang from the University of Adelaide's Waite Research Institute and Shanghai Jiao Tong University's Joint Lab for Plant Science and Breeding, explored the possibility of increasing seed production through ...

Tsukuba, Japan - As far back as the 1930s, inventors have commercialized fuel cells as a versatile source of power. Now, researchers from Japan have highlighted the impressive chemistry of an essential component of an upcoming fuel cell technology. In a study recently published in The Journal of Physical Chemistry Letters, researchers from the University of Tsukuba have revealed successive proton transport--energy transfer--in an advanced carbon-based crystal for future fuel cells, and the chemistry that underpins this phenomenon. Such crystals are exciting as solid electrolytes--energy transfer media--in upcoming fuel cell technologies. Solid electrolytes have advantages, such as high power efficiency and long-term ...

Researchers have revealed that praying mantis (mantids) infected with parasitic hairworms are attracted to horizontally polarized light that is strongly reflected off the surface of water, which causes them to enter the water. In a world-first, these research results demonstrate that parasites can manipulate the host's specific light perception system to their advantage, causing the host to behave in an abnormal manner. This discovery was made by an international research group consisting of Graduate student OBAYASHI Nasono, Associate Professor SAKURA Midori and Associate Professor SATO Takuya of Kobe University's Graduate School of Science, Associate Professor IWATANI Yasushi (Faculty of Science and Technology, Hirosaki University), ...

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a test kit for malaria that delivers results in 30 minutes. The kit could facilitate the diagnosis of malaria in the field, as the equipment needed is anticipated to be lightweight, easy-to-use, and able to detect the disease in its early stages. According to the World Health Organisation (WHO), an estimated 229 million people suffered from malaria in 2019. The disease, transmitted by mosquitoes, caused the deaths of 409,000 people across 87 mainly developing countries. Efforts to treat and control malaria in ...

A microfilter device that can easily separate and capture trace amounts of cancer cells in blood has been developed by a Kumamoto University research group. The palm-sized device is expected to contribute to the development of new cancer diagnostic technologies based on cancer cells in the blood, such as early detection by blood test, postoperative management, and recurrence monitoring. The blood of people with cancer contains trace amounts of cancer cells (CTCs) that have detached from the primary cancer site. However, the amount of these cells is only a few per milliliter, whereas red or white blood cells number in the billions, making ...

INDIANAPOLIS - With the growing prevalence of chronic pain, depression, anxiety, and other symptom-based conditions, physicians and the healthcare systems for which they work are increasingly considering how to augment the care they can provide within the limited time allotted for patient appointments. According to Regenstrief Institute Research Scientist Kurt Kroenke, M.D., writing in the Journal of General Internal Medicine (JGIM), collaborative care can and should play a major role targeting the treatment of symptoms and functional decline, both too frequently marginalized in medically oriented care delivery. Collaborative care is a team-based ...

Neoadjuvant immune checkpoint blockade (ICB) is a promising treatment for melanoma and other cancer types, and has recently been shown to provide a modest survival benefit for patients with recurrent glioblastoma. To improve the treatment efficacy, researchers are looking for vulnerabilities in surgically removed glioblastoma tissues, but this has been difficult due to the vast differences within the tumor and between patients. To address this challenge, researchers at Institute for Systems Biology (ISB) and their collaborators developed a new way to study tumors. The method builds ...
