The Army has a new type of multi-polymer filament for commonly-used desktop 3-D printers. This advance may save money and facilitate fast printing of critical parts at the point of need.
Utilizing human cadaver retinas containing drusen, the researchers used fluorescence lifetime imaging microscopy (FLIM) to measure the light emission from tetracycline staining within those ocular mineral deposits.
A new international study published this week in the journal Nature Communications, applied a novel statistical method that -- for the first time -- captures the important interactions between tides and storm surges. These natural forces are caused by meteorological effects, such as strong winds and low atmospheric pressure, and their impacts have often been difficult to understand because of the complexity of Mother Nature.
University of Tsukuba researchers calculated the efficiencies of four important features of microwave-beam-powered propulsion systems for rockets. These findings are critical to minimizing or possibly reducing the cost of rocket propulsion systems.
Self-assembly is the process that built up life and its surrounding, atom-by-atom. Now, a team of scientists in Turkey has demonstrated the fundamental principles of a universal self-assembly process acting on a range of materials starting from a few atoms-large quantum dots up to nearly 100 trillion atoms-large human cells.
Engineers at the McKelvey School of Engineering at Washington University in St. Louis have received federal funding for a rapid COVID-19 test using a newly developed technology called plasmonic-fluor.
Ke Du and Blanca Lapizco-Encinas, both faculty-researchers in RIT's Kate Gleason College of Engineering, worked with an international team to collaborate on the design of a next-generation miniature lab device that uses magnetic nano-beads to isolate minute bacterial particles that cause diseases. This new technology improves how clinicians isolate drug-resistant strains of bacterial infections and difficult-to-detect micro-particles such as those making up Ebola and coronaviruses.
Inspired by how human bone and colorful coral reefs adjust mineral deposits in response to their surrounding environments, Johns Hopkins researchers have created a self-adapting material that can change its stiffness in response to the applied force. This advancement can someday open the doors for materials that can self-reinforce to prepare for increased force or stop further damage.
Diseases with a genetic cause could be treated by supplying a correct version of the faulty gene. However, in practice, delivering new genetic material to human cells is difficult. A promising method for the delivery of such genes involves the use of DNA/lipid complexes (lipoplexes). Scientists at the University of Groningen have now used advanced simulations to investigate how these lipoplexes deliver DNA fragments into cells. The results can be used to improve their efficiency.
In the first study of its kind, Johns Hopkins researchers provide evidence that an alternative imaging technique could someday replace current methods that require potentially harmful radiation.
