(Max Planck Institute for Chemical Ecology) Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. This was discovered by scientists of the Friedrich Schiller University and the Max Planck Institute for Chemical Ecology in Jena, Germany, together with partners from Belgium. In experiments, Seminavis robusta diatoms directed their orientation either towards nutrient sources or mating partners, depending on the degree of starvation and the need to mate.
(DOE/Sandia National Laboratories) Sandia National Laboratories helped design the first generation of fueling stations for hydrogen-powered cars so that they're as safe as conventional gas stations. Now, Sandia is working to do the same for the next generation of hydrogen stations.
(Yokohama National University) Scientists at Yokohama National University and the University of Tokyo in Japan have designed an ion gel with excellent toughness and an ability to self-heal at ambient temperature without any external trigger or detectable change in the environment such as light or temperature. This new class of material has promising potential for building flexible electronic devices.
(Montana State University) The National Science Foundation grant will allow MSU assistant professor Amy Trowbridge to research the physiological and chemical response of pine trees in drought conditions.
(University of Illinois at Urbana-Champaign) Breaking the bonds between oxygen and hydrogen in water could be a key to the creation of hydrogen in a sustainable manner, but finding an economically viable technique for this has proved difficult. Researchers report a new hydrogen-generating catalyst that clears many of the obstacles -- abundance, stability in acid conditions and efficiency.
(Harvard John A. Paulson School of Engineering and Applied Sciences) A team of Harvard University researchers spent months shaking and rattling swarms of thousands of honey bees to better understand how bees collectively collaborate to stabilize structures in the presence of external loads.
(Carnegie Mellon University) Today, an international group of researchers, including Carnegie Mellon University's Rachel Mandelbaum, released the deepest wide field map of the three-dimensional distribution of matter in the universe ever made and increased the precision of constraints for dark energy with the Hyper Suprime-Cam survey (HSC).
(Rice University) Rice University scientists use a computational method to calculate the optical properties of two-dimensional materials. Their work promises to simplify the process of identifying the right materials for next-generation optoelectronic devices.
(St John's College, University of Cambridge) A new study, led by academics at St John's College, University of Cambridge, used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies.
(Forschungsverbund Berlin) Femtosecond x-ray experiments in combination with a new theoretical approach establish a direct connection between electric properties in the macroscopic world and electron motions on the time and length scale of atoms. The results open a new route for understanding and tailoring the properties of ferroelectric materials.
(Princeton University) How did civilization begin? Where did the division of labor come from? Do successful societies need strong leaders? Princeton and Rockefeller University researchers tackled those giant questions with some very small research subjects: genetically identical ants (Ooceraea biroi) that can live independently or in groups -- and have no queens. They found that simply increasing group size, even if it does not lead to division of labor, can benefit members of the group.
(ETH Zurich Department of Physics) A study exploring the coupling between heat and particle currents in a gas of strongly interacting atoms highlights the fundamental role of quantum correlations in transport phenomena, breaks the revered Wiedemann-Franz law, and should open up an experimental route to testing novel ideas for thermoelectric devices.
(University of Minnesota) Recent research published in Nature Neuroscience by University of Minnesota Medical School neuroscientist Benjamin Saunders, PhD, uses a Pavlovian model of conditioning to see if turning on a light -- a simple cue -- just before dopamine neurons were activated could motivate action.
(American Society of Agronomy) Plants can't do without phosphorus. But there is often a 'withdrawal limit' on how much phosphorus they can get from the soil. A new study looks at how liming, soil management history and enzymes relate to plants' access to phosphorus.
(Ruhr-University Bochum) Chemists at Ruhr-Universität Bochum (RUB) have developed a new, low-cost catalyst for plastic production. It turns a biorefinery product into a starting material for the synthesis of plastics, which could represent a sustainable alternative to widespread PET. At the same time, the potential energy source hydrogen can also be formed during the reaction.
(SLAS (Society for Laboratory Automation and Screening)) Technologies that are reducing costs and changing the ways in which researchers and clinicians process and use therapeutic cells are showcased in the August 2018 special issue of SLAS Technology.
