See bat. See bat run.

It should come as no surprise that bats tend to be poor runners. What should come as a surprise, however, is how well vampire bats can run.

See bat run.

Riskin started out studying how bats of various species move across a surface, which they generally do badly. The least effective of them “just smack their wings against the ground and freak out,” never successfully taking a step, he says.

Other species can shuffle. “The typical bat can get from A to B, but it looks really clumsy while it does it,” Riskin says.

In contrast, he ranks the ground-traversing skills of vampire bats as “off-the-scale good.” The 8-centimeter-long animals move nimbly in any direction, easily making the transition from ground to air movement. They can jump into flight from a standing start in some 30 milliseconds.

What can I do?

Via the Waterboro Public Library, I stumbled across a blog called, appropriately enough, So what can I do? The site explores ways to enact social change. A lot of them, in fact. A lot of the tips seem to be the ‘easy’ sorts of things of which I’m endlessly suspicious—I tend to be skeptical of the social-change-can-be-achieved-through-easy-feel-good-activities school of thought—but it might be the type of thing you’re looking for, in which case, enjoy.

Listening In

Court TV (who else?) brings you a radio series based exclusively on, yes, wiretaps. It’s called the Frank and Fritzy show.

Millennium Ecosystem Assessment

It’s difficult to remain optimistic when “the most comprehensive survey into the state of the planet concludes that human activities threaten the Earth’s ability to sustain future generations.”

On the other hand, at least the report exists.

(I’ll form more of an opinion once I’ve read the report, which you can download online in PDF format.)

Bearing North

The telltale paw prints with huge 10 centimetre-long nails spoke volumes. But now definitive corroborating DNA evidence seals the case of the most northerly sighting of a grizzly bear. The discovery fuels mounting evidence that Canada’s High Arctic is no longer the sole preserve of the polar bear – Nanuk is having to make room for its southern cousin.

Cue ominous music

I’ve been putting this off for a while, mostly because the end of the world seems as good a thing as any to put off till later. But ladies and gents, The End Is Near.

Or might be, anyway:

After analysing the eradication of millions of ancient species, scientists have found that a mass extinction is due any moment now.

Their research has shown that every 62 million years – plus or minus 3m years – creatures are wiped from the planet’s surface in massive numbers.

And given that the last great extinction occurred 65m years ago, when dinosaurs and thousands of other creatures abruptly disappeared, the study suggests humanity faces a fairly pressing danger. Even worse, scientists have no idea about its source.

While a study by Berkeley professors cites this apparent cycle, a separate study by British scientists makes another claim to the end of the world: Supervolcanoes.

(And on a more lighthearted note, Exit Mundi catalogues possible ways of the world ending, from aliens and nuclear war to biotech gone awry and tsunami.)

Your friend, the clock

clockyClocky only wants to help–it’s not his fault his sole task is to drag you out of bed by any way possible.

An exaggeration, of course. But this furry beast of time, devised by a scientist at MIT, does all it can to wake you; after you hit snooze, it rolls away and hides somewhere else in the room before calling out to you.

Hidden, Clocky continues to make noise until you stumble out of bed after him in a sleep-maddened state.

Them

The radiation may make ants grow, but the heat from global warming is liable to shrink them, new research suggests.

Them!

(Though in fairness, the research speaks only of the latter effect. TV land speaks of the former.)

Walkable goodness

The American Podiatric Medical Association ranks the top 10 walker-friendly (U.S.) cities. And they should know.1

  1. Arlington, VA
  2. San Francisco, CA
  3. Seattle, WA
  4. Portland, OR
  5. Boston, MA
  6. Washington, D.C.
  7. NYC
  8. Eugene, OR
  9. Jersey City, NJ
  10. Denver, CO

The list includes links to lots of other info, including stretches for exercise walkers, a true-or-false walking quiz (true!), and a handy-dandy FAQ.

Note:
1 …although the 2004 list does look strikingly different from the 2005 list, potentially indicating that the list is (surprise!) fairly arbitrary, even if the cities included on it are good walkin’ cities.
