Antarctic Climate Research Expedition Trapped In Sea Ice 209

First time accepted submitter Stinky Cheese Man writes "An Antarctic climate research expedition, led by climate researcher Chris Turney of the University of New South Wales, has become trapped in heavy ice near the coast of Antarctica. The captain has issued a distress call and three nearby icebreaker ships are on their way to the rescue. According to Turney's web site, the purpose of the expedition is 'to discover and communicate the environmental changes taking place in the south.'"

Comment Re:Is camping necessary? (Score 1) 173

Why not just open the blinds before bedtime and turn off the lights progressively at night... or whatever the magic is... that does this?

It may not be as simple as staying indoors and opening blinds or reducing lighting at night. The article I read yesterday (here) said the test subjects were exposed to 400% more sunlight when camping outside compared to their usual indoor environment... so sun exposure may also play a role. Considering that Vitamin D (which the body synthesizes in the form of cholecalciferol from sun exposure) acts contrary to melatonin levels (which spike during sleep), perhaps sun exposure provides a strong natural cue for the body's melatonin level to surge at sunset.

Artificial banana flavoring is synthetic isoamyl acetate, amyl acetate and other compounds, whereas actual bananas likely contain hundreds of distinct flavor compounds. Isoamyl acetate by itself is often described as tasting like banana and pear, or Juicy Fruit. My guess is that artificial banana flavoring just isn't as complex as what bananas produce (no pun intended).

The Coming War Against Personal Photography and Video 221

Lauren Weinstein writes "Are you ready for the imagery war — the war against personal photography and capturing of video? You'd better be. 'In some cities, like New York, the surveillance-industrial complex has its fangs deeply into government for the big bucks. It's there we heard the Police Commissioner — just hours ago, really — claim that "privacy is off the table." And of course, there's the rise of wearable cameras and microphones by law enforcement, generally bringing praise from people who assume they will reduce police misconduct, but also dangerously ignoring a host of critical questions. Will officers be able to choose when the video is running? How will the video be protected from tampering? How long will it be archived? Can it be demanded by courts? ... All of this and more is the gung-ho, government surveillance side of the equation. But what about the personal photography and video side? What of individual or corporate use of these technologies in public and private spaces? Will the same politicians promoting government surveillance in all its glory take a similar stance toward nongovernmental applications? Writing already on the wall suggests not. Inklings of the battles to come are already visible, if you know where to look."

Better yet, if you have a Mac you can download Autodesk Inventor Fusion from the App Store for free, and it doesn't expire. Inventor Fusion is quite limited compared to the normal version of Inventor, but it's certainly powerful enough to create interesting/useful objects and export them to STL format for 3D printing. Trimble Sketchup is useful for starting to learn 3D modeling, however it isn't a solid modeler and as such isn't well-suited to 3D printing without using something like CADspan to convert the models to STL. The 3D warehouse in Sketchup is really impressive though and provides a great playground for downloading and working with preexisting models.
