Japanese researchers have succeeded in deriving a theoretical formula that quantitatively predicts the wetting and spreading behavior of droplets that collide with the flat surface of a solid material. In the past, researchers from all over the world have attempted to make quantitative predictions about the extent of wetted areas through experimentation, theory, and numerical analysis, but predictions, particularly during slow collision speeds, have not been realized.
A new simulation based on the von-Kármán-Sodium (VKS) dynamo experiment takes a closer look at how the liquid vortex created by the device generates a magnetic field. Researchers investigated the effects of fluid resistivity and turbulence on the collimation of the magnetic field, where the vortex becomes a focused stream. They report their findings this week in the journal Physics of Fluids.
A national study of college and university administrators has found that female department chairs, deans and provosts have different attitudes and beliefs than their male counterparts about how to retain women professors in STEM fields. It also supports the assertion that placing women in administrative roles creates greater emphasis on the importance of enacting policies to attract and retain women in STEM.
A CSIRO telescope in Western Australia has found its first 'fast radio burst' from space after less than four days of searching.
How you dress, talk, eat and even what you allow yourself to feel -- these often unspoken rules of a group are social norms, and many are internalized to such a degree that you probably don't even notice them. Following norms, however, can sometimes be costly for individuals if norms require sacrifice for the good of the group. How and why did humans evolve to follow such norms in the first place?
For the first time, the world's largest plastic surgery organization is tracking national statistics on gender confirmation surgeries. The American Society of Plastic Surgeons found a nearly 20 percent increase in these surgeries in just the first year of reporting. In 2016, more than 3,200 surgeries were performed to help transgender patients feel more like themselves.
Brown University computer scientists have shown a new way to help prevent users of data exploration software from making false discoveries.
New methods enable people to learn as much as possible from census data for policy-making and funding decisions, while guaranteeing that no one can trace the data back to your household or business. Census-related statistics are used to allocate billions of dollars annually for things like disaster relief, roads and schools. Researchers have developed algorithms that guarantee your information stays private without compromising research about your community.
Breast cancer is one of the most common in women in Italy and in the world. Today it seems possible to design more effective drugs through numerical simulations. This is what has been revealed by research led by CNR and SISSA in Trieste, together with Bellinzona IRB and University of Italian Switzerland. This study analyzed in detail the mechanisms activating an important pharmacological target involved in female hormone synthesis, exceeding the limits of experimental approaches.
Scientists at Princeton University have developed a new algorithm to track neurons in the brain of the worm Caenorhabditis elegans while it crawls. The algorithm, presented in PLOS Computational Biology by Jeffrey Nguyen and colleagues, could save hundreds of hours of manual labor in studies of animal behavior.
