Scientists develop a fluorescence “lifetime” microscopy technique that uses frequency combs and no mechanical parts to observe dynamic biological phenomenaRead more
Multi-domain operations, the Army’s future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots.Read more
One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration has been exploring everyday transistors that are present in billions in all our mobile phones for their use as qubits.Read more
A team of New Jersey researchers has shown that gait training using robotic exoskeletons improved motor function in adolescents and young adults with acquired brain injury.Read more
Improved radiotherapy techniques and technologies allow an increasing number of children diagnosed with cancer to survive long into adulthood. Unfortunately, the very treatments that save their lives are associated with several severe, life-threatening, or even fatal chronic health conditions.
For example, children who received radiation therapy are at a heightened risk of developing heart disease later in life. Further improving radiation treatments to minimize this risk requires a deep understanding of the relationship between radiation exposure and heart disease that is currently lacking. A multi-institutional team of researchers in the US has enhanced a critical computational tool to enable new insights into this relationship.
Identifying anatomic changes shown on MRI scans during a course of pencil-beam proton therapy, and adapting treatment plans accordingly, could improve the treatment quality, effectiveness and safety. In a retrospective study, researchers at St. Jude Children’s Research Hospital determined that 27% of paediatric patients, the majority with brain tumours, would have benefited from mid-treatment plan changes.Read more
A low-cost, portable brain MRI scanner could expand access to MR neuroimaging, as well as enabling point-of-care diagnostics for neurological emergencies. With this aim, researchers at Massachusetts General Hospital/Harvard Medical School are developing a portable scanner based on a compact, lightweight permanent magnet.Read more
Researchers have developed an assay that can detect the presence of SARS-CoV-2 in a nasal swab using a device attached to an ordinary smartphone, they report December 4 in the journal Cell. Although more research is needed before such a test can be rolled out, the results are promising and ultimately may be applicable to screening more broadly for other viruses.Read more
Researchers at the US National Institute of Standards and Technology have now developed a solution based on a suite of sensors that detects the capacitance of liquid inside a spacecraft’s fuel tank and uses these data to reconstruct a three-dimensional picture of the remaining fuel.Read more
Researchers from the University of Houston, the Texas Heart Institute and the University of Chicago have developed an implantable rubber patch that can collect information about the heart and use it to diagnose cardiac conditions.Read more
