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.

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.
