Material scientists at the University of Jena have developed a bone replacement based on calcium phosphate cement and reinforced with carbon fibers. The fibers increase damage tolerance and ensure that cracks in the material repair themselves.
Making catalysts to convert waste carbon dioxide into useful industrial products has been expensive and complicated -- until now. UNSW engineers show it's as easy as playing with Lego.
MicroRNAs (miRNAs) are gaining more attention in researches. To achieve fast and highly sensitive profiling of miRNAs, a research team from City University of Hong Kong (CityU) has developed a novel high-throughput intracellular biopsy technique that isolates targeted miRNAs from living cells within around 10 minutes by using diamond nanoneedles. The technique is simple and can be applied to other aspects, from the nucleic acid testing of viruses (e.g. COVID-19) to early cancer diagnosis.
Scientists from Kyushu University and Kumamoto University in Japan have developed a molecule capable of being a catalyst for three different hydrogen reactions--hydrogen splitting for energy generation, hydrogen formation for fuel production, and hydrogen addition for hydrogenation--by mimicking the structures of the three types of naturally occurring hydrogenase enzymes depending on how it twists.
Small and minimally invasive 'Detachable Microneedle Depots' effectively deliver stem cells for localized MSC therapy of skin disorders.
An algorithm which analyses MRI images and automatically detects small changes in knee joints over time could be used in the development of new treatments for arthritis.
Chemotherapy has been the lone suspect in a neurological ailment, but cancer also appears to be to blame. The havoc they wreak together is much more than additive.
Two exceptional strains of tuberculosis, isolated from East African patients with multi-resistant forms of the disease have been discovered. Genome analyses show that this lineage originated from an ancestral phylum which predates the branching point shared by all other lineages of common tuberculosis strains known to date. This discovery reinforces the hypothesis of an East African origin for the tuberculosis bacillus and provides additional molecular clues about the evolution towards a pathogenic lifestyle.
A new machine learning approach classifies a common type of brain tumour into low or high grades with almost 98% accuracy, researchers report in the journal IEEE Access. Scientists in India and Japan, including from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS), developed the method to help clinicians choose the most effective treatment strategy for individual patients.
An international team of scientists has said the artificial structures and reclaimed land that are now commonplace in coastal urban areas all over the world are often poor surrogates for the natural environment they replace.
