Grr! Arrgh! Nearly-extinct predators make a comeback

fisherHorror writers in search of a plot need look no further: a weasel-like predator known as the fisher is making itself right at home in your Northeast or Midwest suburbs! The mixture of eco- and morality tale make it the perfect story device, given that they were almost wiped out by trappers and foresters in the last century, but reintroduced to prey on porcupines. The New York Times describes a householder’s encounter with a fisher that tried to eat her German shepherd’s face:

“I had never seen anything like it,” Ms. Beaudry recalled. “I didn’t know what it was. It kind of looked like a fox. But it was very, very ratty looking and had fangs and claws. It was creepy looking, but not that big.”

More animals-out-of-place news: The Caribbean monk seal, extinct. The Chinook salmon, endangered in the U.S., is thriving so well in Chile and Argentina that it could disrupt freshwater and marine ecosystems. And there’s thumbnail-sized quagga mussels clogging up the Colorado River. What other displaced creatures might be cast in near-future fiction?

Eat it, Crichton

pieeyedemuPaleontologist Jack Horner has a better way to resurrect dinosaurs than all that tedious mucking about with mosquitoes and blood and amber. Far easier to start with a bird and work backwards. Avian DNA already contains instructions to make tailbones, teeth, scales, and claws. In “Dinosaurs: Return to Life?”, a Discovery Channel documentary, Horner says he would start with an emu, which looks halfway like a velociraptor anyway. A chicken would do in a pinch. (Unfortunately, the show does not seem to be scheduled for rerun anytime soon.)

Has Michael Swanwick written this story yet?

Science: It Really Is Everybody’s Business

T-Rex of Dinosaur ComixA museum public-relations coordinator for a Texas museum was the first to discover a fossil of a duck-billed dinosaur while touring a dino dig in Montana. A paleontologist says he would have missed it:

I knew enough never to go to a ridge top because you don’t find specimens there. But I forgot to tell that to Steven, so he did exactly that and proved me wrong.

Got Change for an Electron?

Ella at the whiteboardIsraeli scientists have sliced electrons into “quasiparticles,” each with a quarter charge of the electron.

Although electrons are indivisible, if they are confined to a two-dimensional layer inside a semiconductor, chilled down to a fraction of a degree above absolute zero and exposed to a strong magnetic field that is perpendicular to the layer, they effectively behave as independent particles, called quasiparticles, with charges smaller than that of an electron.

Quasis have been known for 20 years, but they were “odd fractionally charged” — one third of an electron, one fifth, etc. The quarter-charges behave differently and may be useful for computing.

Those of us who have trouble wrapping our heads around quantum stuff might sympathize with astronomers, who, the New York Times tells us, are finding cosmology just as puzzling.

As far as astronomers can tell, there is no relation between dark matter, the particles, and dark energy other than the name, but you never know.

Nevertheless, string theorist Brian Greene, promoting the World Science Festival, reminds us of something most readers of this site would probably find a truism, but is probably a new idea to a lot of people:

We must embark on a cultural shift that places science in its rightful place alongside music, art and literature as an indispensable part of what makes life worth living.

The Wire

Personally, I won’t believe it till I hear some guy on cable screaming about it at the top of his lungs. But how about a nanowire-mesh “paper towel” that can clean up 20 times its weight in oil, and recycle the gunk for future use? It might filter and purify water, too.

The new material appears to be completely impervious to water. “Our material can be left in water a month or two, and when you take it out it’s still dry,” [MIT materials scientist Francesco] Stellacci said. “But at the same time, if that water contains some hydrophobic contaminants, they will get absorbed.”
