More than 2,000 years ago, Egyptians offered cats to the gods. Now, a new study published in the Journal of Archaeological Science suggests that even cats destined for the gods did not necessarily live pampered lives.

Theft is almost universally considered an exploitative behavior. The conventional view underlying judicial systems is that the act of taking resources from others without offering compensation stems from moral and personal failings. As a result, these systems rely on the assumption that the threat or imposition of punishment will motivate criminal offenders to adjust their future behavior. Yet the outcome is not always success.
Most of us spend much of our day staring at organic light-emitting diodes, or OLEDs, which convert electricity into light to produce the colorful displays on smartphones, computer monitors and televisions. Although metal-free light-emitting materials that produce all colors are in demand, it has been difficult to make ones that efficiently emit orange-to-red light. Now, researchers led by the University of Osaka have shown that such materials do not need to be held in a rigid shape to work well: flexible molecules that can change shape can also emit orange-to-red light.
Cobalt phosphide (CoP) is a promising alternative to platinum for producing hydrogen from water. However, scientists have struggled to explain why it performs so well. Computer models have suggested that CoP should become unstable under the conditions used to produce hydrogen, yet experiments show that it remains active and durable in acidic, neutral and alkaline environments.
