Synthetic azetidines could help simplify drug design for neurological diseases


Chemists found a simple route to synthesize azetidines, precursors that make it easier for drug designers to access nitrogen atoms that are key to building new compounds. Číst dále >>> Přeložit do en

Scientists can now control thermal profiles at the nanoscale


Scientists have designed and tested an experimental system that uses a near-infrared laser to actively heat two gold nanorod antennae to different temperatures. The nanorods are so close together that they are both electromagnetically and thermally coupled. Yet the team measured temperature differences between the rods as high as 20 degrees Celsius and could change which nanorod was cooler and which was warmer, even though the rods were made of the same material.

How Do Companies Lose Billions And Still Stay Afloat?


Watch Video Uber announced it lost  $5.2 billion  in just one quarter — its biggest loss ever. So how do companies lose so much money and still stay afloat?Think of a company like a family. Every month, families try to balance their income with expenses, and many try to have some money set aside for emergencies. Let's say an unexpected car repair causes costs to go up one month. With money that's set aside, this hypothetical family is able to get the car fixed and still be OK financially.So right now, you could think of Uber's $5.2 billion loss as a temporary hiccup. But if it keeps happening, the company could land in some serious financial trouble. And with Uber specifically, there's another variable to consider: future value.Investors who pour money into startups like Uber often do so because they see the potential for success, and  experiencing losses  in the beginning is normal. When profits are down, Uber can look to other metrics to demonstrate success — like increases in the number of active monthly users.So short-term losses aren't always terrible. Companies can plan ahead for that, and investors can look past it — as long as things turn around eventually. Číst dále >>> Přeložit do en

Herní monitory se rychle vyvíjejí, od té doby, co se tento segment nastartoval příchodem 120–144Hz panelů a poté technologiemi adaptivního obnovování (G-Sync, později FreeSync). Teď v něm výrobci posunuli „hranice možného“ na další metu. Je tu první monitor s 240Hz frekvencí, který jí dosahuje ne na panelu typu TN s horší kvalitou obrazu, ale na obrazovce typu IPS. Tato […] Příspěvek Je tu první IPS monitor s 240Hz frekvencí, Acer Nitro XV273X. Má i 1ms odezvu GtG pochází z Cnews.cz Číst dále >>>
