Simulations cast doubt on unusual asteroid’s ‘dark comet’ status

Science via Phys.org
Quick Read

In 2031, Japan's Hayabusa2 spacecraft will arrive at the near-Earth asteroid 1998 KY26: a tiny body that is accelerating in a way that astronomers have struggled to explain. Some studies have suggested that the asteroid is pushed along by water escaping from it as gas, making it an as-yet theoretical "dark comet."

Repeat thieves without kleptomania struggle to adapt to rewards in decision-making test

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.

Team designs molecules that efficiently generate orange-to-red light for OLED displays

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.

A catalyst that protects itself while producing hydrogen

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.
