Driving to Devon Island Across Sea Ice – Update: Track Progress Live

Mars Institute team to complete Arctic sea-ice drive along fabled Northwest Passage to reach "Mars on Earth"

"An international team led by Mars Institute scientist Dr. Pascal Lee will depart the Arctic community of Resolute Bay today aboard the Moon-1 Humvee Rover on a sea-ice crossing expedition. The team is headed for the Haughton-Mars Project Research Station (HMPRS) on Devon Island, High Arctic, a remote outpost dedicated to space exploration on the world's largest uninhabited island. The Moon-1 is an experimental vehicle simulating future pressurized rovers that will one day allow humans to explore long distances on the Moon and Mars. Last year, the scientists completed a record-setting 494 km drive on sea-ice in the Moon-1 along the fabled Northwest Passage between Kugluktuk and Cambridge Bay, Nunavut."

Keith's update: You can follow the Moon-1 Humvee as it traverses the ice between Cornwallis Island and Devon Island here LIVE via SPOT. Status reports are online here. As you can see, they are now on the sea ice.

Keith's note: ARC PAO is deliberately ignoring this activity even though it is coordinated at ARC. Go figure. FAIL.

Scientists Craft Tiny Transistor Powered by Your Own Cellular Fuel | 80beats

IonPumpThe structure of Aleksandr Noy’s new transistor is unimpressively simple: just a carbon nanotube connecting two metal electrodes. But what makes it special is what he and his team use to control it: adenosine triphosphate (ATP), the fuel from our own cells. The project, published in a study in Nano Letters, achieves a key step in unifying man and machine.

The way it works: An insulator coats the ends of the nanotube, but not the middle—it’s left exposed.

The entire device is then coated again, this time with a lipid bi-layer similar to those that form the membranes surrounding our body’s cells [New Scientist].

Finally, the team poured a solution of ATP plus potassium and sodium across the transistor. That created an electric current, one that was stronger the more ATP they poured.

The magic is in the lipid bi-layer, which contains an ATP-sensitive protein that serves as a kind of ion pump when ATP is present. The lipid hydrolyses ATP molecules, with each occurence causing three sodium ions to move one way through the lipid and two potassium ions to move the other way, netting one charge across the bi-layer to the nanotube [Popular Science].

Noy claims to have created “the first example of a truly integrated bioelectronic system,” New Scientist says. And as simple as the transistor is, the idea behind it—harnessing the energy already in our bodies to power electronics—will be one of the keys to creating battery-free devices that monitor our cells, connect to our brains, or do things we won’t think of until we’ve (finally!) got nanodevices hooked up to our brains.

Commercial Space Enables Exploration

Going commercial frees NASA for deeper space, Alan Stern, Orlando Sentinel

"The administration's wise commercialization approach echoes an immensely successful path taken by NASA in the past. Consider: At the dawn of the Space Age, all satellites were built and launched by governments. But early on, communications satellites were encouraged to go commercial. The result: a $100 billion-plus spinoff industry that employs thousands of workers to build the satellites, their ground stations, launchers and associated command and control infrastructure. It also launches more satellites annually than any other form of spaceflight. The money saved frees NASA to do other things with its resources."

Kitchen Renovations, Part 3

Reconstruction

Once the walls in my kitchen were bare, it was time to cover them again. I had decided to use the moisture-resistant drywall, which I have always known as greenboard. To my surprise, what I knew as greenboard was actually purple at my local hardware store.

DIY Engine Pulleys and Carbon Fiber Interior

In this episode, Motorz TV shows you how to install underdrive engine pulleys and a carbon fiber interior. There are two installs in this segment, both on 2008 Ford Mustang GTs.

The first install explains how to upgrade stock underdrive pulleys to reduce accessory drag and impro

VPN Latency Problem

Does anyone have any experience with VPN on Sat Internet?

I am told that due to latency that I can not setup a VPN.

Does anyone know of a work around, I need to be able to connect to my work PC and change programs.

Is there a way of setting up the VPN so that w

Cellphones Now Used More for Data Than for Calls

From New York Times:

For many Americans, cellphones have become irreplaceable tools to manage their lives and stay connected to the outside world, their families and networks of friends online. But increasingly, by several measures, that does not mean talking on them very much.

How to Walk on Water

From Coolest Gadgets:

The first time I saw this image of a man walking on the water, I just assumed it was a special effect. There is a video of it after the jump, and it's either a grandiose hoax or the next extreme sport. I can't help but want to believe that it is the latter.

The Pennsylvania Medical Humanities Consortium, May 19-20, College of Physicians, Philadelphia PA


Friend of Morbid Anatomy Todd Vladyka has just let me know about a rather exciting looking consortium taking place next week at the College of Surgeons (home of the Mütter Museum); highlights include an entire panel devoted to "The 'Art' of Anatomy and Other Collections," which will consist of a presentation devoted to the art of Joseph Maclise (as seen above), and two other presentations entitled "The Exquisite Cadaver and the Evolution of the Anatomic Theater"and "Constituting the Syphilitic Collector."

The opening lecture--"What Mark Twain Might Tell Us (And Ask Us) If He Could Join Us Tonight"--is free and open to the public; $25 for students or $50 for non-students will gain you admission to all the other events.
