Through the nano hole: lego technique reveals the physics of DNA transport through nanopores

Researchers at the University of Leicester have developed a new method to recycle electric vehicle batteries using a ground-breaking new approach that many will have experienced in the dentist's chair. The Faraday Institution project on the recycling of lithium-ion batteries (ReLiB) led by Professor Andy Abbott at the University of Leicester used a new method, involving ultrasonic waves, to solve a critical challenge: how to separate out valuable materials from electrodes so that the materials can be fully recovered from batteries at the end of their life. Current recycling ...

A new corona test developed at the University Hospital Bonn can analyze a large number of swabs simultaneously using sequencing technology and has a similarly high sensitivity as the common qPCR test. The innovative method offers great potential, especially for systematic testing in daycare centers, schools or companies. Today, the results of the study on the new Corona test have been published in the renowned journal "Nature Biotechnology". Bonn, 6/29/2021 - In addition to vaccination, systematic testing of the population remains of central importance in order to effectively monitor and contain the spread of infections during the Coronavirus pandemic. Only in this way can the spread of the virus be effectively monitored and ...

Crystallization is one of the most fundamental processes found in nature - and it's what gives minerals, gems, metals, and even proteins their structure. In the past couple of decades, scientists have tried to uncover how natural crystals self-assemble and grow - and their pioneering work has led to some exciting new technologies - from the quantum dots behind colorful QLED TV displays, to peptoids, a protein-mimic that has inspired dozens of biotech breakthroughs. Now, a research team led by scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley has developed a nanoparticle composite that grows ...

The electronic properties of graphene can be specifically modified by stretching the material evenly, say researchers at the University of Basel. These results open the door to the development of new types of electronic components. Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice. The material is very flexible and has excellent electronic properties, making it attractive for numerous applications - electronic components in particular. Researchers led by Professor Christian Schönenberger at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel have now studied how the material's ...

Mineral resources from Chile are of great importance to Germany. According to statistics from the World Bank, thousands of tons of valuable minerals are imported from the South American country every year, including raw materials for lithium-ion batteries. But their extraction causes ecological and social problems: "The use of the limited freshwater resources in northern Chile for mining regularly fuels conflicts with the local population," says Professor Thomas Kohl from KIT's Institute of Applied Geosciences (AGW). "Northern Chile is one of the driest regions on earth, but has extensive geothermal resources. With a novel type of plant, it is not only possible to generate electricity in a climate-friendly way, but also to extract ...

When positioned strategically, garment seams sewn with conductive yarn can be used to accurately track body motion, according to computer scientists at the University of Bath in the UK. Best of all, these charged seams are able to respond to subtle movements that aren't picked up by popular fitness trackers, such as watches and wristbands. In a new study, the Bath researchers found that clothing made with conductive seams can be analysed to identify the wearer's movements. PhD student Olivia Ruston, who presented the work at the ACM Designing Interactive Systems conference this month, said: "There are lots of potential applications for conductive yarn in any activity where you want to identify and improve ...

Mice are an important animal model of human vision due to the powerful genetic tools available in this species. However, mouse vision was thought to be different to that of humans because humans have a region of the retina specialized for fine details called the 'fovea' whereas mice do not. Researchers from the Netherlands Institute of Neuroscience (NIN) have shown that the visual cortex of mice does contain a region of enhanced visual sensitivity dubbed the 'focea', making the mouse a better model of human vision than previously expected. The findings were published ...

Lithia, Florida -- June 29, 2021 -- Surgical resident training has traditionally occurred in a master-apprentice-type relationship, with graduated responsibilities until trainees are expected to perform procedures on their own. Given recent changes in the health care system, including reduced operating room time, increased difficulty of procedures and working hour restrictions, there is less time for residents to learn using traditional methods. Researchers from the University of Manitoba and the Pan Am Clinic recently published a paper in the journal Arthroscopy, Sports Medicine, ...

Aerosol generated by playing woodwind and brass instruments is less than that produced when vocalising (speaking and singing) and is no different than a person breathing, new research has found. The findings, published online in the journal Aerosol Science and Technology, could be crucial to developing a roadmap for lifting COVID-19 restrictions in the performing arts, which have been significantly restricted since the start of the pandemic. The research project, known as PERFORM (ParticulatE Respiratory Matter to InForm Guidance for the Safe Distancing of PerfOrmeRs in a COVID-19 PandeMic), was supported by Public Health England, the Department for Digital, Culture, Media and Sport (DCMS), and UKRI and was carried out by a collaborative team from ...

The death of neurons specialised in the synthesis of dopamine, one of the brain's main neurotransmissors, deteriorates the motor and cognitive capacities of those with Parkinson's disease. The loss of these neurons is related to alpha-synuclein aggregation. Recent studies show that oligomers, the initial aggregates of this protein, are the most pathogenic forms of α-synuclein and are responsible for the spreading of the disease in the brain. Therefore, one of the more promising approaches in fighting this disorder consists in neutralising these oligomers and, thus, slow down the pathological progression. ...
