The US Air force has received orders to launch nuclear missiles from land based silos. Two airmen turn their keys simultaneously and... nothing happens. One airman picks up a red phone and dials. A pleasant automated voice reports that "You have called when our lines are unusually busy. Please hold for the next nuclear launch assistant." After a few minutes, the line is ans

Taken together, it appears that the US biotech industry has been the main driver of innovative drugs over the past ten years. I don't want to belittle the follow-on compounds, because they are useful. (As pointed out here before, it's hard for one of those compounds to be successful unless it really represents some sort of improvement over what's already available). At the same time

I am building a transfer switch that has two 12v DC inputs and one 12v DC output, current is 10A peak and 4A normally. The switch could comprise 2 pairs of back-to-back P-channel MOSFETs, (the back-to-back prevents reverse flows through the MOSFET's body diode). Should one input fail I need to switch between inputs fast enough such that the output remains on but it is not switching at h...

What is the difference between these two network chips ? My main worry is "connection issues"... like Intel I225-V "Products formerly Foxville"... Which one is newer: Realtek RTL8125 or Realtek RTL8125BG ? I think the BG version/revision ? but not sure... Bye, Skybuck.

The emergence of disease-causing bacteria that are resistant to antibiotics is often attributed to the overuse of antibiotics in people and livestock. But researchers have homed in on another potential driver of resistance: antidepressants. By studying bacteria grown in the laboratory, a team has now tracked how antidepressants can trigger drug resistance1. “Even after a few
