Nature is full of examples of large-scale collective behavior; humans also exhibit this behavior, most notably in pelotons, the mass of riders in bicycle races. Using aerial video footage of bicycle races, researchers analyzed peloton motion to determine what causes changes in the group's large-scale collective behavior and found that riders move through the peloton in a manner similar to circulation in a fluid.
Using a highly-detailed musculoskeletal model of an echidna forelimb, Harvard scientists are not only shedding new light on how the little-studied echidna's forelimb works, but are also opening a window into understanding how extinct mammals might have used their forelimbs.
The time of day, determined by a cell's internal clock, has a stronger influence on cell division than previously thought, reveals a new study.
There are two major shapes of bacteria, i.e., rod-shape and spherical shape. The genus Deinococcus consists of rod-shape and spherical shape species.
How can a doctor predict the treatment outcome of an individual patient? Traditionally, the effectiveness of medical treatments is studied by randomized trials, but is this really the only reliable way to evaluate treatment effectiveness, or could something be done differently? How can the effectiveness of a treatment method be evaluated in practice? Could some patients benefit from a treatment that does not cause a response in others? A new method developed by Finnish researchers now provides answers to these questions.
Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab at Aarhus University. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems.
In a paper published Oct. 8 in the journal Nano Letters, a team from the University of Washington and the National Tsing Hua University in Taiwan announced that it has constructed functional metalenses that are one-tenth to one-half the thickness of the wavelengths of light that they focus. Their metalenses, which were constructed out of layered 2D materials, were as thin as 190 nanometers -- less than 1/100,000ths of an inch thick.
Scheduling and coordinating air traffic can be difficult, but taking the airlines' and passengers' delay costs into account can actually save airlines money and result in fewer delays, according to a new study from Binghamton University, State University of New York.
Study explains how partisan groupings evolve to become extreme, ultimately resulting in the formation of 'echo chambers' in which political beliefs go unchallenged and increase in strength.
Virginia Tech researchers found a way to give high-performance computing data systems the flexibility to thrive with a first-of-its-kind framework called BespoKV, perhaps helping to one day achieve the HPC goal of performing at the exascale, or a billion billion calculations per second.
