For molecular motors to be exploited effectively, they need to be able to operate in unison. However, integrating billions of these nanometer-sized motors into a single system, and getting them to operate in unison has proved to be quite a challenge. Organic chemists at the University of Groningen have now succeeded in integrating numerous unidirectional light-driven rotary motors into a metal-organic framework (a solid material with a 3D cage-like structure).
In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall past experiences tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval.
A breakthrough by engineers at The University of Texas at Austin offers new solution through solar-powered technology that absorbs moisture from the air and returns it as clean, usable water. This 'super-sponge' could be used in disaster situations, poverty-stricken areas and developing countries.
An international team from the Universities of Cordoba, Cambridge and Zurich conducted a study on bullying roles among peers. Children who are involved in bullying at age 11, may remain involved throughout their entire adolescence
Researchers at DOE's Lawrence Berkeley National Laboratory have developed a platform that uses living cells as 'scaffolds' for building self-assembled composite materials. The technology could open the door to self-healing materials and other advanced applications in bioelectronics, biosensing, and smart materials.
Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals perform whole-body regeneration, and uncovered a number of DNA switches that appear to control genes used in the process.
Using roundworms, one of Earth's simplest animals, Rice University bioscientists have found the first direct link between a diet containing too little vitamin B12 and an increased risk of infection by two potentially deadly pathogens.
A team of scientists from the Helmholtz Zentrum Muenchen, the Juelich Research Center, the Technical University of Munich and the Heinrich Heine University Duesseldorf has shown that harmless purple bacteria (Rhodobacter) are capable of visualizing heterogeneity in tumors. With the aid of optoacoustic imaging, the researchers used these microorganisms to visualize macrophages (Greek for 'big eaters'), that also play a role in tumor development. Their research findings have now been published in Nature Communications.
UW researchers have created a novel system that can measure platelet function within two minutes and can help doctors determine which trauma patients might need a blood transfusion upon being admitted to a hospital.
A novel machine-learning 'toolbox' that can read and analyse the sequences of proteins has been described today in the open-access journal eLife.
