Aging In Salmon Depends On Choosy Bears

Ancient Meteor Blast Peppered Mammoths With "Shrapnel"
Many of the animals, particularly in the region near present-day Alaska, didn't survive.
That's the story being pieced together by a research team led by Richard Firestone of the Lawrence Berkeley National Laboratory in Berkeley, California.
The team had done previous work on a suspected impact that occurred 13,000 years ago. But while looking for evidence of that more recent blast in mammoth tusks, the scientists found traces of the much older event.
"The surprise was the tusks were dating back to 30,000 to 34,000 years ago," Firestone said.
"Nobody had thought of it before. It was serendipitous."
The work was presented this week at the fall meeting of the American Geophysical Union in San Francisco, California.

Bizarre rodent with ears bigger than its head is caught on camera for first time
"The footage and images really are extraordinary, incredibly charming - cute and comic in equal measure," says Dr Jonathan Baillie, the ZSL head of field conservation who led the exhibition to track down and assess this most elusive species in the Gobi.
"But there's more to the long-eared jerboa than that. It represents millions of years of evolutionary history. While it looks like a small rodent, it is very distinct. There's no other animal of its type."
Sadly, it's also an animal that may soon be limited to textbooks and folklore. For while the tiny silky-haired rodent described as the Mickey Mouse of the desert has only just made its debut on the global stage, it may shortly be heading the way of the Dodo.
Thanks to climate change, pollution, illegal mining and (rather surprisingly, since it lives in the middle of a desert) the domestic cat, its numbers are in free-fall.
Though its habitat is so remote no one knows exactly how many exist, experts estimate the population has dropped by more than 80 per cent over the past decade, and it is on the official list of the 100 most endangered creatures on the planet.

Sea Lice From Fish Farms May Wipe Out Wild Salmon
Four years from now wild pink salmon may vanish from Canada's Broughton Archipelago, a new study warns.The killers, according to the research, are sea lice from fish farms.
Scientists previously demonstrated that juvenile wild pink salmon often catch lethal sea lice infestations when they swim through areas where salmon are raised in open-net farms.
Now for the first time researchers have used a data-driven model to calculate the impact on the wild salmon population.
"It's severe," said Martin Krkosek, a fisheries ecologist at the University of Alberta in Edmonton, Canada, who led the study.
(Krkosek is a National Geographic Society Expeditions Council grantee. The National Geographic Society owns National Geographic News.)
According to the data, the current rate of decline will take the salmon from their historical abundance to extinction in eight years, or four generations. The decline started two generations ago.

Wild chimpanzees may not have menopause
Together with recent data from wild gorillas and orangutans, the finding -- described this week in the journal Current Biology -- suggests that human females are rare or even unique among primates in experiencing a lengthy post-reproductive lifespan.
"We find no evidence that menopause is common among wild chimpanzee populations," says lead author Melissa Emery Thompson, a postdoctoral researcher in anthropology at Harvard University. "While some female chimpanzees do technically outlive their fertility, it's not at all uncommon for individuals in their 40s and 50s -- quite elderly for wild chimpanzees -- to remain reproductively active".

Animal Hero or Dognapper?

The trial began Wednesday for an animal rights activist accused to stealing a dog she claims was being mistreated by her owner. Thought the defendant, Tammy Grimes admits to taking the dog the defense is not acknowledging the crime to amount to theft. While the law states that animals amount to personal property and subject to theft, the animal rights activists claim "dogs are much more than that".
Terry Nelson-Bunge, the State College representative for Dogs Deserve Better, said she believes Grimes had no choice but to take the dog.
And now I ask you: who's more annoying animal rights activists or cops? Usually, I would argue cops (you know, the fear, the bright lights, the abuse of power) but this time? I just don't know. No choice but to take the dog? That just belies a complete misunderstanding of what the word choice means. Seriously.

Glow-in-the-Dark Cats Could Make For a Unique Home Lighting Solution
If you ask me, cats that could truly glow-in-the-dark would make for an unique and styilsh night-light. And, much like the new Litrospheres, they last for about 12 years. The only downside is that the latter requires no power source while cats require a steady diet. Still, the crazy cat lady down the street could have the most power efficient house in town.

Humane Society Traces Expensive Pups to Pet Mills
The investigation looked at dog breeders, pet auctions and pet stores that form a chain of supply for the expensive dogs that can be found along the streets of Beverly Hills, often in sweaters and rhinestone collars.
These so-called puppy mills are large-scale breeding operations that have a reputation for abuse, inbreeding and filthy conditions.
“These puppy mills apply an agricultural mind-set to the breeding of dogs,” said Wayne Pacelle, president of the Humane Society of the United States. “Often, they’re run by farmers who raise soybeans and corn, and this becomes another, more lucrative cash crop for them. It often becomes a dominant source of income because no money is spent on the care of these dogs.”
The tiny toy breeds that sit in wooden baby cribs at the Bel-Air store, Pets of Bel Air, sell for upward of $1,000 and are popular among the young Hollywood set.
“We’re not singling out Pets of Bel Air as the sole operation at fault,” Mr. Pacelle said. “But they are representative.”
In a videotape made in the store by the Humane Society of the United States, Paris Hilton drifts by at one point, staring at the upper shelves. Her Chihuahua’s limbs dangle over her arm and its little head scans the room. The video, taken using a hidden camera, also shows a manager telling an employee not to let customers know the extent of one puppy’s health problems.
