Realistic Starfleet meetings

Dan Hon (previously at BB) noticed that Star Trek’s meetings and conferences always involve military officers, usually occur with ample time for preparation, yet invariably has them just talking to one another. If there are any graphics involved, they are simple, concise and expressive. This is of course nothing whatsoever like any military on earth…

EVs are hardly the magic wand to fight India’s pollution woes

India’s drive towards electric vehicle (EV)-led mobility has accelerated in recent years, but the plan raises more environmental questions than it answers.For one, the charging infrastructure is expected to be heavily reliant on coal-based power, indirectly increasing the emission of greenhouse gases. Then, there’s the bigger question of what to do with the heap of…

Device recycles waste heat into light to boost solar systems

Arrays of aligned single-wall carbon nanotubes could channel wasted heat and greatly raise the efficiency of solar energy systems, report researchers. The new invention is a hyperbolic thermal emitter that can absorb intense heat that would otherwise spew into the atmosphere, squeeze it into a narrow bandwidth, and emit it as light that can be…

Young Jupiter was smacked head-on by massive newborn planet: Jupiter’s core may still be reeling from collision 4.5 billion years ago

A colossal, head-on collision between Jupiter and a still-forming planet in the early solar system, about 4.5 billion years ago, could explain surprising readings from NASA’s Juno spacecraft, according to a study this week in the journal Nature. Astronomers from Rice University and China’s Sun Yat-sen University say their head-on impact scenario can explain Juno’s…
