Investigating the implications of social robots in religious contexts
Researchers at Siegen University and Würzberg University, in Germany, have recently carried out a study investigating the user experience and acceptability associated with the use of social robots in religious contexts. Their paper, published in Springer's International Journal of Social Robotics, offers interesting insight into how people perceive blessing robots compared to other robots for more conventional purposes.

Manipulating electron spin using artificial molecular motors
Artificial molecular switches and machines have undergone rapid advances over the past several decades. Particularly, artificial molecular motors are highly attractive from the viewpoint of chirality switching during rotational steps. Now, researchers fabricated an electron's spin-filtering device that can switch the spin polarization direction by light irradiation or thermal treatment. The present results are beneficial to the development of solid-state functionalities emerging from nanosized motions of molecular switches.

Four new species of plume moths discovered in Bahamas
Deborah Matthews hunts for plume moths in darkness, waiting for the halo of her headlamp to catch a brief flicker. About the size of mosquitoes, the delicate, feathery moths fly only a few feet at a time. Matthews must watch for that short flight while keeping clear of poisonwood, cracks in the limestone and sinkholes, common hazards of fieldwork in the Bahamas.

Scholars investigate how mirror activity works
A team of researchers from Germany and Russia, including Vadim Nikulin from the Higher School of Economics, have demonstrated that long contraction of muscles in one hand increases involuntary reaction of the other one. Meanwhile, the time between muscle contractions in both hands decreases. The results of the study have been published in Neuroscience.

Everything will connect to the internet someday, and this biobattery could help
In the future, small paper and plastic devices will be able to connect to the internet for a short duration, providing information on everything from healthcare to consumer products, before they are thrown away. Researchers at Binghamton University, State University of New York have developed a micro biobattery that could power these disposable sensors.

Researchers find ways to hackproof smart meters
Smart electricity meters are useful because they allow energy utilities to efficiently track energy use and allocate energy production. But because they're connected to a grid, they can also serve as back doors for malicious hackers.
