... Beyond awesome. This is Darwinian evolution mixed with, like, Burning Man.

Being scientists of biomimicry, the authors surmise that if it were possible to reverse-engineer the entire shell — it’s not just the outer iron layer that’s cool; there are also two inner layers with gooey nougat that are equally important in defending the snail — they could produce superstrong materials for military defense and “load-bearing”.

Fair enough. But personally I’m satisfied just to have more pure science that proves, yet again, the inexhaustible Weirdness Of The Briny Deep.

Iron snails, people! Iron snails.

Experts shocked by 'bizarre' swan divorce
Experts at a wildlife sanctuary in Gloucestershire have witnessed a rare ''divorce'' between two Bewick's swans - with both parties bringing their new partners to winter at the site.
24 Jan 2010

It is only the second time in more than 4,000 pairs of Bewick's swans studied over 40 years at Wildfowl and Wetlands Trust centre at Slimbridge that a separation has been recorded.

It is not unheard of for the birds, which usually mate for life, to find a new mate but it tends to be because one of the pair has died.

So when male swan Sarindi turned up in the annual migration from Arctic Russia without his partner of two years Saruni and with a new female - newly-named Sarind - in tow, conservationists feared the worst for Saruni.

But shortly afterwards Saruni arrived at the wetlands site - also with a new mate, Surune.

And after observing them, the experts are confident the old relationship had ended and new ones had begun.

Julia Newth, wildlife health research officer at Slimbridge, said the "bizarre" situation had taken staff by surprise. ...

Dolphin and bat DNA on the same wavelength

A new study has shown that echolocation evolved separately, but through the same genetic changes, in both dolphins and bats.

Scientists at Queen Mary, University of London have shown that the remarkable ability is shared by these very different animals at a much deeper level than anyone previously realised – all the way down to the molecular level.

Writing in the journal Current Biology, they describe how dolphins and bats have both evolved the same specialised form of inner-ear hair cells that allow them to use sophisticated echolocation: detecting unseen obstacles or tracking down prey by making a high frequency noise and listening for the echo that bounces back.

"The natural world is full of examples of species that have evolved similar characteristics independently, such as the tusks of elephants and walruses," said Stephen Rossiter of Queen Mary's School of Biological and Chemical Sciences. "However, it is generally assumed that most of these so-called 'convergent traits' have arisen by different changes in the animal's DNA. Our study shows that this very complex ability - echolocation - has in fact evolved by identical genetic changes in bats and dolphins." ...

Echolocating bats and whales share molecular mechanism

ANN ARBOR, Mich.---With high-pitched squeaks, clicks and chirps and ultra-sensitive hearing, toothed whales and some bats zero in on prey by emitting pulses of sound and interpreting the echoes that bounce back.

Over the course of evolution, the two groups acquired this remarkable ability independently, for use in very different environments, so you'd expect the means by which each accomplishes the feat to differ. Surprisingly, that's not the case, a new study by researchers at the University of Michigan suggests.

"The seemingly different echolocation abilities that evolved independently in whales and bats have a similar underlying molecular mechanism," said Jianzhi (George) Zhang, professor of ecology and evolutionary biology. The finding overturns conventional thinking that the evolutionary phenomenon known as convergence is rare at the molecular level. The research is reported in the Jan. 26 issue of the journal Current Biology. A separate paper by another research group, published in the same issue of the journal, reports similar results.

In traits such as appearance and behavior, convergence---the acquisition of similar structures or abilities in different lineages---is a well-known biological curiosity. Birds and bats separately developed wings and the ability to fly, for example; elephants and walruses each ended up with tusks. But because similar structures can be built from different blueprints, it's unusual for these superficial similarities to share molecular underpinnings. ...

Leaf-like sea slug feeds on light
Last Updated: Friday, January 22, 2010

A green sea slug found off North America's east coast not only looks like a leaf, but can also make food out of sunlight, just like a plant.

U.S. researchers have found that the sea slug Elysia chlorotica can photosynthesize, using energy from light to convert carbon dioxide into sugars.

"If you shine light on these slugs, they fix carbon dioxide and make oxygen just like a plant," Sidney Pierce of the University of South Florida told CBC Radio's Quirks & Quarks.

Pierce reported his findings Jan. 7 at the annual meeting of the Society for Integrative and Comparative Biology, and has submitted his research to the journal Symbiosis. ...

Monarch butterflies reveal a novel way in which animals sense the Earth's magnetic field
January 25, 2010

Building on prior investigation into the biological mechanisms through which monarch butterflies are able to migrate up to 2,000 miles from eastern North America to a particular forest in Mexico each year, neurobiologists at the University of Massachusetts Medical School (UMMS) have linked two related photoreceptor proteins found in butterflies to animal navigation using the Earth's magnetic field.

The work by Steven Reppert, MD, professor and chair of neurobiology at UMMS; Robert Gegear, PhD, research assistant professor of neurobiology; Lauren Foley, BS; and Amy Casselman, PhD, is described in the paper, "Animal cryptochromes mediate magnetoreception by an unconventional photochemical mechanism," to be posted on-line in the journal Nature January 24. ...

The animal was spotted by Kate Arkless Gray, 29, on Saturday night as she made her way home from a friend's wedding.

She watched in amazement as the fox boarded the escalator at Walthamstow Central just after midnight to leave the station.

Miss Arkless Gray said: "As I got off the train and headed towards the up escalator I saw this daring creature dashing full speed down the down escalator, which was taped off for maintenance workers at the bottom.

"I was wishing I'd been able to film it and then the workers at the bottom of the escalator shooed him back up again."

She then managed to capture the surreal scene as the fox casually made his ascent on the escalator back towards the exit. ...

Dog given medal after 'canine CPR'

A central Queensland dog which jumped up and down on its owner's chest after the man suffered a massive heart attack may have saved his life.

Teka the three-year-old Australian cattle dog has been given the RSPCA's animal achievement award following the 2007 feat at a glass factory near Bundaberg.

Owner Jim Touzeau's heart stopped and he collapsed unconscious on the factory floor when Teka climbed onto his chest and began to jump repeatedly with all four paws.

The dog also barked in his face, rousing him enough to raise the alarm with his son.

She also ran outside and barked to attract attention.

Medical experts have been unable to say whether the canine CPR had any medical impact but say Mr Touzeau would not be alive today if not for Teka's efforts.

"I don't know if she actually kick-started my heart. But the doctors said that if I hadn't come to and called for help the chances are I would be dead," Mr Touzeau said.

"My heart had definitely stopped."

The 79-year-old glass craftsman also suffered deep cuts when he fell and sliced himself open on plate glass at the his Tinana factory.

He has since been fitted with a defibrillator implant.

"I lost my wife six years ago this Christmas and it's a pretty lonely life on your own,'' he told brisbanetimes.com.au.

"I got Teka three years ago and she's a terrific companion. She just never leaves my side. Because it's just the two of us, I rely on her and she relies on me."

Mr Touzeau said he remembered nothing of the heart attack, but recalled waking up to Teka on his chest.

"She was really thumping my chest with her two front feet,'' he said.

"It was out of the blue [behaviour] for her.

"She must have been thinking 'I better wake this fella up or I won't get any dinner'.''

The RSPCA will present the state-based commendation to Teka today and will also nominate her for a Purple Cross - the charity's highest bravery medal.

RSPCA spokesman Michael Beatty said Teka had shown incredible intuition.

"This award isn't given away lightly. If she hadn't been there he probably would not have woken up."



Ta much, dear Edosan
All sorts of things hopped thru my head as I read this. I should point out I'm a major bunny fan and have owned two wonderful rabbits.

1. Rabbit overpopulation ain't easy to ahem fix

2. If they're that big a problem in the city center FFS, then the wildlife folks should shut the hell up and focus on the bunnies in the boonies

3. What kind of arsehole turns a pet rabbit free in fucking *Sweden*? It gets *cold* up thar!

4. Were they doing this with rats no one would object

5. You breed *pets* dude, and no one would ask you to sell your *pet* bunnies for biofuel

6. Get a grip, yo

“When I saw them making hooks I had to rein in in my enthusiasm in case they saw it and reacted to that, but these are fantastic findings. Birds’ brains are so differently constructed from primates’ it’s amazing that they can carry out similar tasks.” The results of the study are published today in the Proceedings of the National Academy of Sciences. ...

... "The exact cause of mortality of affected bats is not yet fully understood, but the newly identified fungus is considered a likely contributor," Marvin Moriarty, northeast regional director of the U.S. Fish and Wildlife Service, told the natural resource committee yesterday.

The fungus invades the skin, underlying tissue and particularly the wings, which help to balance complex physiological processes such as body temperature. All six bat species that hibernate in the Northeast have been impacted and scientists fear the syndrome will spread to large bat populations in the South and Southwest -- and that some species may never recover even if a solution is found.

"Bats differ from most other small mammals in that they have long lives and reproduce slowly," Moriarty said.

Bats are insect-eaters and help human agriculture. The 1 million killed would have consumed 8,000 pounds of insects in a single summer night, scientists said.

"The level of nightly consumption by one little brown bat would be equivalent to a 150-pound teenage boy eating approximately 300 quarter-pounders. Translated to the number of insects that would not be eaten by one little brown bat in your backyard on a given night, it amounts to the equivalent of 60 medium-sized moths or over 1,000 mosquito-sized insects," said Thomas Kunz, director of the Center for Ecology and Conservation at Boston University.

Deer shatters window, interrupts breakfast
Six-point buck leaves through front door after crashing into home.

WEST BLOOMFIELD TOWNSHIP -- The Luke family was enjoying coffee Sunday morning when they heard a noise so loud they thought a car had driven straight through their West Bloomfield ranch.

Instead, Keith Luke found a 6-point buck in his study.

The deer had leaped through his double-pane picture window. He was bleeding severely and cowering behind the couch.

"When I saw he was injured, I ran to the front door and opened it so he had a way to escape," said Luke, at home with his wife and son. "I think he was as bewildered as everyone else was."

In a township where deer are common, a buck jumping through a picture window is "extremely rare" and perhaps unheard of until Sunday, said West Bloomfield Police Sgt. Erik Tilli.

Police and fire crews arrived at the Lukes' home in the 2300 block of Keylon Drive around 11:30 a.m. Sunday after the deer had exited. "It looked like a crime scene in here," Luke said. ...

The Detroit Zoo welcomed a baby aardvark this month.

Zoo officials are awaiting DNA test results to determine the sex of its newborn aardvark, Amani (Swahili for “peace”), born at 1:05 a.m. Dec. 8 to mother Rachaael and father Mchimbaji.

The 23-inch infant arrived hairless, weighing 3 pounds, 10 ounces, with ears measuring 4 inches. “This baby can only be described as hideously cute,” said Director of Conservation and Animal Welfare Scott Carter. “Rachaael is a first-time mother and is showing great maternal instincts.” ...
