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

LG is best known for productivity-oriented laptops and particularly, its lightweight Gram 17 — but not any serious gaming models. Now the company has revealed what it calls its "first gaming laptop" with some high-end specs. The 17-inch UltraGear 17G90Q model packs an 11th-generation Intel Tiger Lake H CPU, NVIDIA GeForce RTX 3080 Max-Q graphics, up to 32GB of RAM and 1TB of storage. It also comes with a 300 Hz 1080p IPS display, and should have pretty decent endurance for gaming or content creation with the 93Wh battery. There's a good selection of ports, including a USB 4 Gen 3x2 (Type C) with Thunderbolt 4, another USB-C 3.2 2x1, two USB 3.2 Gen 2x1, HDMI, microSD, headphone jack and RJ45. Other features include a power button fingerprint sensor and 1080p webcam. LG It's got an aluminum case with an attractive grey/purple color scheme and is fairly slim for a 17-inch gaming laptop (21.4mm). It's decently lightweight at 5.82 pounds, though a bit heavy compared...

'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...
