Understanding conditions for star formation

Researchers have demonstrated how a gas escapes ice at an extremely cold temperature, providing insight into star formation in interstellar clouds. The mechanism by which hydrogen sulphide is released as gas in interstellar ...

Letting molecular robots swarm like birds

The world's smallest "swarm robot" measures 25 nanometers in diameter and 5 micrometers in length, and exhibits swarming behavior resembling motile organisms such as fish, ants and birds.

Is punishment as effective as we think?

A game to study human behavior has shown punishment is an ineffective means for promoting cooperation among players. The result has implications for understanding how cooperation has evolved to have a formative role in human ...

Strong hosts help parasites spread farther

Large, physically strong Masu salmon disperse farther when infected with parasites, potentially escaping from further infections at the contaminated site but ironically resulting in the greater expansion of the parasite, ...

Reusing waste energy with 2-D electron gas

More than 60 percent of the energy produced by fossil fuels is lost as heat. Thermoelectric energy conversion has attracted much attention as a way to convert waste heat from power plants, factories and cars into electricity. ...

'Ion billiards' cue novel material synthesis method

A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to "ion billiards." The new method could pave the ...

Cloud formation suppressed by biogenic organic emissions

Researchers have found evidence that near-ground biogenic emissions of organics suppress cloud formation in cool-temperate forests in autumn, providing clues to how global warming will affect cloud formation and the overall ...
