Astronomers Hunt Universe’s Earliest Secrets From Moon’s Far Side

『V』๐šƒ『B』Casts┋
Researchers aim to study the universe’s ‘Dark Ages’ using a quiet orbit around the Moon. Their small satellite will search for ancient hydrogen signals and cosmic clues. Astronomers hope to uncover insights about the ‘Cosmic Dawn’ by deploying a small spacecraft designed to detect an “ancient whisper” from space while orbiting the far side of [...]

The Sex Lives of Guppies Just Got Way More Colorful

Guppies aren’t just flashy for fashion — new research shows that bright orange males are actually more virile. Scientists at UBC used deep learning and multigenerational breeding to show that color isn’t just attractive to females, it’s genetically tied to brain development and sexual behavior. The more vibrant the guppy, the more likely he is [...] http://dlvr.it/TLwMmJ

'Squeezed' light might produce breakthroughs in nano-sized electronics

It's one thing to produce nanoscale devices, but it's another to study and improve on them — they're so small they can't reflect enough light to get a good look. A breakthrough might make that possible, however. UC Riverside researchers have built technology that squeezes tungsten lamp light into a 6-nanometer spot at the end of a silver nanowire. That lets scientists produce color imaging at an "unprecedented" level, rather than having to settle for molecular vibrations. The developers modified an existing "superfocusing" tool (already used to measure vibrations) to detect signals across the entire visible spectrum. Light travels in a flashlight-like conical path. When the nanowire's tip passes over an object, the system records that item's influence on the beam shape and color (including through a spectrometer). With two pieces of specrtra for every 6nm pixel, the team can create color photos of carbon nanotubes that would otherwise appear...
