Mar 15, 2023 (Nanowerk News) In a step forward for genetic engineering and synthetic biology, researchers have modified a strain of Escherichia coli bacteria to be immune to natural viral infections while also minimizing the potential for the bacteria or their modified genes to escape into the wild. The work...

Mar 14, 2023 (Nanowerk News) Electrochemical DNA biosensors hold significant promise for monitoring of various diseases. Overall, their detection applications are vast, from target DNA analytes such as bacterial genes and tumor sequences to clinically relevant concentrations of SARS CoV-2 biomarkers, for example. However, to achieve appropriate sensitivity and selectivity...

Mar 15, 2023 (Nanowerk News) An international team led by researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) have found the earliest evidence of parts of the universe that were heated to temperatures more characteristic to the intergalactic gas medium where most atoms...

Mar 15, 2023 (Nanowerk News) Researchers at ETH Zurich, Empa and EPFL are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured in the shoe and thus during any activity. This helps athletes or patients to determine performance and therapy progress. In...

Mar 14, 2023 (Nanowerk News) In a paper published in SCIENCE CHINA Chemistry ("Tracking lithiation with transmission electron microscopy"), the research progress of transmission electron microscopy study on Li ion battery materials has been reviewed in three aspects: analytical TEM to directly identify Li ions, cryo-TEM technique to explore beam-sensitive...

Mar 14, 2023 (Nanowerk News) Each year, an estimated two trillion dollars is lost globally due to counterfeit products ranging from jewelry to medicine. As current security labels and product authentication methods are rapidly becoming obsolete or easy to hack, there is a rising urgency for more secure anti- counterfeiting...

Mar 14, 2023 (Nanowerk News) When it comes to studying particles in motion, experimentalists have followed a 100-year-old theory that claims the microscopic motion of a particle is determined by random collisions with molecules of the surrounding medium, regardless of the macroscopic forces that drive that motion. Scientists at Lawrence...

Mar 14, 2023 (Nanowerk News) When astronauts begin to build a permanent base on the moon, as NASA plans to do in the coming years, they’ll need help. Robots could potentially do the heavy lifting by laying cables, deploying solar panels, erecting communications towers, and building habitats. But if each...

Mar 14, 2023 (Nanowerk News) Researchers at West Virginia University have engineered a material with the potential to dramatically cut the amount of heat power plants release into the atmosphere. A team led by Xueyan Song, professor and George B. Berry Chair of Engineering at the Benjamin M. Statler College...

Mar 14, 2023 (Nanowerk News) COVID is not yet under control. Despite a bevy of vaccines, monoclonal antibodies, and antivirals, the virus continues to mutate and elude us. One solution that scientists have been exploring since the early days of the pandemic may come in the form of tiny antibodies...
