Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction.

What gives a 3-meter-long Amazonian fish some of the toughest scales on Earth

Arapaima gigas is a big fish in a bigger river full of piranhas, but that doesn't mean it's an easy meal. It's evolved armor-like scales that deform, but don't tear or crack, when a piranha — which has one of the animal kingdom's most powerful bites — attacks. Researchers describe the unique properties of the Amazonian Arapaima skin and its potential for human-made materials.

A team chemically engineered carbon nanotubes to synthesize and trap trions at room temperature. Trions are quasi particles that can potentially carry more information than electrons in applications from bioimaging to chemical sensing and quantum computing. The research makes it possible to manipulate trions and study their fundamental properties in ways that have never been possible before.

How hunger makes food tastier: A neural circuit in the hypothalamus

Using optogenetic and chemogenetic techniques, researchers have identified brain circuits underlying hunger-induced changes in the preferences for sweet and aversive tastes in mice. These circuits involved Agouti-related peptide-expressing neurons, which projected to glutamate neurons in the lateral hypothalamus. From there, glutamate neurons projecting to the lateral septum increased sweetness preferences, and glutamate neurons projecting to the lateral habenula decreased sensitivity to aversive tastes.

A catalyst's utility is influenced by its surface charge and how that charge is transferred. Until recently, studying charge transfer has relied on complex imaging techniques that are both expensive and time-consuming. Scientists now report an approach for studying charge transfer that does not rely on complicated equipment — simplifying the real-time observation of catalysis.

Society is rejecting facts; medical researchers can help

Anecdotes, fake news and social media have created a skeptical and misinformed public who is rejecting the facts. A commentary says that medical researchers must help the public understand the rigorous process of science and help them to discern an anecdote from peer-reviewed scientific results. The best way to do this? By continuing to ensure integrity, rigor, reproducibility and replication of their science and to earn the public's trust by being morally responsible and completely free of any influences.
