Arctic Climate Change Study Canceled Due to Climate Change (livescience.com)
A Canadian expedition to study climate change in the Arctic has been canceled due to climate change. Specifically, the icebreaker CCGS Amundsen had to be cancelled "due to complications associated with the southward motion of hazardous Arctic sea ice," reports University of Manitoba. From the report: This regrettably postpones the much-anticipated Hudson Bay System Study (BaySys) involving 40 scientists from five universities across Canada. Timing was key for this $17 million, four-year, University of Manitoba-led project. The need to deal with extreme ice conditions in the south meant the ship would arrive too late on site to meet research objectives. This year the Expedition Logistics and Science Teams accelerated the mobilization of the 2017 Arctic Expedition to permit departure of the Amundsen six days ahead of schedule. This would allow CCG to carry out critical marine safety and security operations in the unusually severe ice conditions in the Strait of Belle Isle and along the northeast coast of Newfoundland before beginning the Science Mission. Unfortunately, the conditions required much more extended support than anticipated. Fleet management issues and inadequate alternative ships forced the cancellation of the science program due to significant safety concerns. This decision to cancel the BaySys 2017 program was not made lightly. Although the cancellation was due to circumstances beyond control of the Expedition Team, every effort was made to develop a viable option to allow this valuable work to proceed. -
The Physics of Beer Bubbles
Roland Piquepaille writes "Yesterday, I told you about virtual beer. Today, we follow two North America researchers who are studying the physics of real beer bubbles. 'Singly scattered waves form the basis of many imaging techniques such as radar or seismic exploration.' But pouring beer in a mug involves multiply scattered acoustic waves. They are more complex to study, but they can be used to look at various phenomena, such as predicting volcanic eruptions or understanding the movement of particles in fluids like beer. They also could be used to monitor the structural health of bridges and buildings or the stability of food products over time. Read more for additional references and a photo showing how the researchers monitor beer bubbles." -
Build Your Own LCD Bus Schedule
MikeLRoy writes "An engineering student in Winnipeg, tired of missing his bus to school (and waiting in the cold) created an LCD bus stop. It displays the next bus times for several stops and routes, all from the heated comfort of his kitchen. And yes, there are pics and code on the site." -
802.11 RF Amp
MikeLRoy writes "Linksys has announced a signal amp, to be available soon, for their wireless ap's/routers. While many people have been using commercial rf amps hacked onto their ap's, linksys now has a commercial solution!" I wonder when ISPs are going to stop soft-pedaling the anti-NATing provisions in their terms of service.
