Researchers have developed a simple model to study how ants balance their large heads relative to their body size. Such models may have useful applications in bio-inspired designs.
Suitable catalysts are of great importance for efficient power-to-X applications -- but the molecular processes occurring during their use have not yet been fully understood. Using X-rays from a synchrotron particle accelerator, scientists of the Karlsruhe Institute of Technology have now been able to observe for the first time a catalyst during the Fischer-Tropsch reaction that facilitates the production of synthetic fuels under industrial conditions.

Consider this scenario: A vaccine for the novel coronavirus has been developed that is 91.27% effective. If public health officials present this information using the specific number, people are likely to think the vaccine is actually less effective than if it is presented as being 90% effective. This concept is a real-life application of recent findings from Gaurav Jain, an assistant professor of marketing in the Lally School of Management at Rensselaer Polytechnic Institute, published recently in Organizational Behavior and Human Decision Process.
Without stem cells, human life would not exist. Due to them, a lump of cells becomes an organ, and a fertilized egg develops into a baby. But what actually makes a stem cell? Are these a stable population of specially gifted cells? Scientists at the Institute of Science and Technology (IST) Austria discovered that instead, stem cells might emerge due to the collective behavior of cells within the organs.
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this "dead water" being understood. A French team has explained this phenomenon for the first time.
Research explains how a unicellular marine organism generates light as a response to mechanical stimulation, lighting up breaking waves at night.
Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of "ecosystem engineers" stabilizes the entire network against extinctions.
A new study by the University of Plymouth explains for the first time how quantum supercomputers could be helpful in the world of making and performing music
Researchers from Duke University propose a new approach to finding an optimal solution for controlling large numbers of robots collaboratively completing a set of complex linear temporal logic commands called STyLuS*, for large-Scale optimal Temporal Logic Synthesis, that can solve problems massively larger than what current algorithms can handle, with hundreds of robots, tens of thousands of rooms and highly complex tasks, in a small fraction of the time.
Residents in all 25 of the US counties hardest hit by COVID-19 began to limit their public movements six to 29 days before states implemented stay-at-home orders, according to Johns Hopkins University researchers.
