Here's an incredibly cool video showing the prow of a massive ice breaking ship as it plows through Antarctica's Ross Sea. The footage is sped up, to pack two months of travel into five minutes. But, unlike a lot of time-lapse videos, this one also has a really informative audio track, in which marine scientist Cassandra Brooks waxes poetic about the many different kinds of ice and explains why she and her team were out there, breaking through the stuff, to begin with.
Bonus: At the end, you get to see the absolute adorableness that is penguins on high-speed fast forward.
This morning, Marketplace Tech Report had a story on a new cellulose-based building material that could be made by genetically engineered bacteria — altered versions of the bacteria that naturally make stuff like kombucha. This tech sounds like it's got a long way to go from laboratory to the real world, but if they can perfect the process and make it large enough quantities, what you'd end up with a strong, inexpensive goop that could be used to build everything from medical dressings, to digital paper, to spaceships. Yes, you could theoretically use this stuff to make rocket casings, according to R. Malcolm Brown, Jr., a professor of cell biology at UT Austin. And if you can build a rocket from this stuff, you could also break the same material back down into an edible, high-fiber foodstuff. — Maggie
In a study of 6,455 semen samples (yup), scientists at Israel's Ben-Gurion University of the Negev found that human sperm were most atheletic — and were found in the highest concentrations — in winter. There was a marked decrease in sperm motility and numbers in spring, summer, and fall. It's an interesting and logical addendum to the fact that sperm counts and motility decrease in men who subject their testicles to warm conditions; in hot tubs, say, or a pair of overly tight underpants. — Maggie
This excerpt from the new book, Toms River by Dan Fagin, has me instantly intrigued. The book is about one of the rare places where scientists were able to prove that not only was there a cluster of cancer cases, but that those cases could be linked to a cause. The excerpt explains why this is such a rare thing. Turns out, just because it looks like a town has more cancers than it should, doesn't mean that's always what's going on. — Maggie
Let's just play this safe and assume that, until more samples have been collected and detailed DNA analysis has been done, the real answer to the question, "Is bacteria found in Antarctica's Lake Vostok actually new to science or just contamination from the drilling?" is "We don't really know." This is a great example of why making scientific pronouncements from the field, before you've had time to do the really in-depth analysis that goes into writing a peer-reviewed research paper, can be problematic. Right now, you've got different camps of researchers making totally contradictory claims. Who is right is, so far, anybody's guess. — Maggie
Say you're a marine biologist and you want to study the little bitty creatures of the sea — shrimps and worms and things like that. How do you go about capturing them?
Why, with an underwater vacuum, of course.
At the PNAS First Look blog, David Harris writes that this "SCUBA-tank powered vacuum, called an “airlift,” inhales shrimp, sand fleas, marine worms, and 'things that would swim away if they had the chance.'"
The town of Macapá is in the north of Brazil, on the coast, where the Amazon River flows into the Atlantic. On December 5th, 2001, Sir Peter Blake and his crew decided to spend the night there. They were on their way back to the ocean after a journey down the Amazon, documenting the effects of climate change for the National Geographic Society.
That night, while their guard was down, a group of masked bandits boarded the boat.
John Mark Ockerbloom's "From Wikipedia to our libraries" is a fabulous proposal for creating research synergies between libraries and Wikipedia, by adding templates to Wikipedia articles that direct readers to unique, offline-only (or onsite-only) library resources at their favorite local libraries. Ockerbloom's approach acknowledges and respects the fact that patrons start their searches online, and seeks only to improve the outcomes of their research -- not to convince them not to start with the Internet.
So how do we get people from Wikipedia articles to the related offerings of our local libraries? Essentially we need three things: First, we need ways to embed links in Wikipedia to the libraries that readers use. (We can’t reasonably add individual links from an article to each library out there, because there are too many of them– there has to be a way that each Wikipedia reader can get to their own favored libraries via the same links.) Second, we need ways to derive appropriate library concepts and local searches from the subjects of Wikipedia articles, so the links go somewhere useful. Finally, we need good summaries of the resources a reader’s library makes available on those concepts, so the links end up showing something useful. With all of these in place, it should be possible for researchers to get from a Wikipedia article on a topic straight to a guide to their local library’s offerings on that topic in a single click.
I’ve developed some tools to enable these one-click Wikipedia -> library transitions. For the first thing we need, I’ve created a set of Wikipedia templates for adding library links. The documentation for the Library resources box template, for instance, describes how to use it to create a sidebar box with links to resources about (or by) the topic of a Wikipedia article in a reader’s library, or in another library a reader might want to consult. (There’s also an option for direct links to my Online Books Page, if there are relevant books online; it may be easier in some cases for readers to access those than to access their local library’s books.)
Basic science — the kind of research done for curiosity's sake, in order to better understand how parts of our world work — is the foundation of applied science — research that's aimed at developing a product, or tool, or achieving a goal. In the United States, the federal government is, by far, the number one funding source for basic research. So what happens to that investment in our future when things like the Sequester come along? Obviously, funding goes down. But the details are what's important here. Tom Levenson explains the short-term and long-term impacts.— Maggie
Researchers at the Lawrence Berkeley National Laboratory are studying how the seemingly innocuous things we do in our homes and offices can have big impacts on our health. One of those things is cooking, because the way we cook can affect the air we breathe. Scientists are trying to figure out how to make houses safer, but to do that, they need to understand how people use houses — what we cook in them and how we cook it. You can help by taking this quick, anonymous survey. — Maggie
