A University of Rochester biologist invented an inexpensive and environmentally friendly method for making artificial nacre using an innovative component: bacteria. The artificial nacre is made of biologically produced materials and has the toughness of natural nacre, while also being stiff and, surprisingly, bendable. The method used to create the novel material could lead to new applications in medicine, engineering -- and even constructing buildings on the moon.
Researchers from ETH Zurich demonstrate that genetically identical cells exhibit differing responses in their motility towards chemical attractants. Average values hide the full picture when it comes to describing the behavior of bacteria.
Conducted by Professor Fariba Deghani, Dr. Golnoosh Torabian and Dr. Peter Valtchev as part of the ARC Training Centre for the Australian Food Processing Industry that was established within the university's Faculty of Engineering and IT, the study showed that compounds from elderberries can directly inhibit the virus's entry and replication in human cells, and can help strengthen a person's immune response to the virus.
Japanese scientists at Tokyo University of Agriculture and Technology and Yokohama National University have identified the molecular mechanism that gives the skin secretions of a species of frog effective antimicrobial properties. Unravelling the molecular mechanism that facilitates antimicrobial activity of these peptides can help us better understand how the defense system of the frog has evolved, and how this can be used to fight microbial infections of medical importance.
Motor vehicle crashes are one of the most common causes of TBI-related emergency room visits, hospitalizations and deaths. Yet, much of TBI research is focused on military or sports-related injuries. University of Arizona aerospace and mechanical engineering professor Samy Missoum is working to identify the threshold separating car crashes that cause TBIs from those that don't.
Scientists at the University of Bristol have invented a new technology that could lead to the development of a new generation of smart surgical glues and dressings for chronic wounds. The new method, pioneered by Dr. Adam Perriman and colleagues, involves re-engineering the membranes of stem cells to effectively 'weld' the cells together.
Researchers from Queen Mary University of London and University College London have developed a new approach to repair defects in fetal membranes which could prevent life-long medical conditions and disabilities associated with preterm birth.
Researchers at Binghamton University, State University of New York have developed a method to treat bacterial infections which could result in better wound care.
Human skeletal muscles have a unique combination of properties that materials researchers seek for their own creations. They're strong, soft, full of water, and resistant to fatigue. A new study by MIT researchers has found one way to give synthetic hydrogels this total package of characteristics: putting them through a vigorous workout
Superinjection, the effect used in lasers and LEDs creation can work in 'pure' semiconductors, which was previously considered impossible. This opens up new prospects for designing highly efficient blue, violet, ultraviolet, and white LEDs, as well as light sources for optical wireless communication (Li-Fi), new types of lasers, transmitters for the quantum internet, and optical devices for early disease diagnostics.
