'Living fossil' coelacanth genome sequenced.

"And if you think about it, this might be correlated to the fact that the coelacanth lives in a rather extreme and stable environment. It lives several hundred metres down in the ocean, and it may also be in an environment where it doesn't have a lot of competitors. So maybe it adapted to that environment a long time ago and it doesn't have a huge need for change."

Who knew that being a crotchety old thing, set in its ways, could be a good thing? Rolleyes

Works for me. Drinking Beverage

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method.

I thought that fish looked familiar! Blink

(So, can we call you a fossil, then? Consider )

Footage reveals how insects use their bodies to hover.

"The moth moves its body by pivoting its abdomen up and down to fine-tune the effect of the forces that keep the insect airborne."

Who knew that moths were into belly dancing... Drinking Beverage

And of course, if I am going to be talking about moths, I just have to post this:



The leaded window opened
to move the dancing candle flame
And the first Moths of summer
suicidal came.
And a new breeze chattered
in its May-bud tenderness ---
Sending water-lillies sailing
as she turned to get undressed.
And the long night awakened
and we soared on powdered wings ---
Circling our tomorrows
in the wary month of Spring.
Chasing shadows slipping
in a magic lantern slide ---
Creatures of the candle
on a night-light-ride.
Dipping and weaving --- flutter
through the golden needle's eye
in our haystack madness. Butterfly-stroking
on a Spring-tide high.
Life's too long (as the Lemming said)
as the candle burned and the Moths were wed.
And we'll all burn together as the wick grows higher ---
before the candle's dead.
The leaded window opened
to move the dancing candle flame.
And the first moths of summer
suicidal came
to join in the worship
of the light that never dies
in a moment's reflection
of two moths spinning in her eyes.

Learned Helplessness in Flies and the Roots of Depression.

'The researchers now show that flies experiencing uncomfortable levels of heat will walk to escape it. But if the flies realize that the heat is beyond their control and can't be avoided, they will stop responding, walking more slowly and taking longer and more frequent rests, as if they were "depressed."'

And because I seem to be into an entomological mood these days:

Love at First Sniff: Male Moths Go by First Impressions.

"Once male moths lock onto a pheromone plume, they are much less attuned to blend quality," Dekker said. "In other words, males fly even to blends that were initially unattractive, and so can mate with females of different strains that they would not have approached otherwise, explaining why we find hybrid moths in nature... But after taking flight, the males "relax their specificity," that is, they are less particular about which lures they fly to."

Men! Rolleyes

At least we don't go around biting the heads off our mates while still copulating...just saying Big Grin

And at least we are not so stupid as to stubbornly go looking for something to hump, even when it's going to kill us.

Just sayin' right back atcha Drinking Beverage
