According to new research published in the journal Human Nature, competitive team games are universal across the world and may have deep roots in humans’ evolutionary past; among hunter-gatherers, these games enable men to hone their physical skills and stamina, assess the commitment of their team members, and see how each performs under pressure. Scalise Sugiyama et al analyzed how competitive team sports shaped the physical and psychological skills...

This is an artist's impression of the SN 1987A remnant. The image is based on real data and reveals the cold, inner regions of the remnant, in red, where tremendous amounts of dust were detected and imaged by ALMA. This inner region is contrasted with the outer shell, lacy white and blue circles, where the blast wave from the supernova is colliding with the envelope of gas ejected from the star prior to its powerful detonation.

Excitation spectra of the Higgs-like state: (a) excitation spectra of the Higgs-like state for different interaction strengths, 1/(kFa); the different levels of background condensate fraction are due to the different 1/(kFa); the solid lines shows the Gaussian fit to the high-frequency side of the spectra; the error bars show the standard deviation of approximately four measurements; (b) time-of-flight image of the condensate with the thermal background subtracted at 1/(kFa)=−0.43; rings indicate momentum intervals of 0.02kF; (c) momentum-resolved analysis of the Higgs excitation inside the condensate by averaging the optical density in the color-coded rings in (b) for different modulation frequencies; the resonance occurs at the same modulation frequency for all momenta.

This artist’s impression shows ‘Oumuamua, the first interstellar object discovered in our Solar System. Recent observations show that the object is moving faster than predicted while leaving the Solar System. Astronomers assume that venting material from its surface due to solar heating is responsible for this behavior. This outgassing can be seen in this artist’s impression as a subtle cloud being ejected from the side of the object facing the Sun. Image credit: NASA / ESA / Hubble / ESO / M. Kornmesser.
