Cheetahs’ Secret Weapon: A Tight Turning Radius [New York Times]
"Anyone who has watched a cheetah run down an antelope knows that these cats are impressively fast. But it turns out that speed is not the secret to their prodigious hunting skills: a novel study of how cheetahs chase prey in the wild shows that it is their agility — their skill at leaping sideways, changing directions abruptly and slowing down quickly — that gives those antelope such bad odds."

A few months ago, The Cincinnati Zoo challenged Cheetah Outreach
to a little race. At stake? The future of a species
...and bragging rights as the world's fastest mammal.
Sarah, an eight-year-old cheetah from Cincinnati, made the first runs in this race. She set a record of 6.13 second over 100 meters.
This shaved about 1/20 of a second off the old record (6.19 seconds). By way of comparison, Usain Bolt
covers this distance in a leisurely 9.58 seconds.
South Africa's Cheetah Outreach's competitor, Zaza
, will make her runs later this month or early next.

Polar bears of Churchill, Manitoba.
Wildlife photographer Ken Bereskin has a nice collection of polar bears
frolicking in the snow. This itchy bear
is so frustrated, he's using the rippled ice of a frozen lake to
scratch himself. If you need a change of temperature, he also has over 500 images
of wildlife from Uganda and Kenya, including big
(a mother cuddling
, a cheetah chomping
down on a gazelle
, and a young lioness shredding
a skeleton to pieces
eating the cheetah's leftovers, a black-headed heron eating
a venomous boomslang snake
, and a scary-looking
taking it all in from above). He also has a smaller
of desert wildlife from the dunes of Etoshia National
Park in Namibia. (His real job is working for Apple, and he has a
that hasn't been updated in eons, but evidently that's not as much fun
as chasing after hungry carnivorous animals in the sweltering heat, or
risking frostbite in the snow).

But what about the kitties? Feline Immunodeficiency Virus
. FIV has been recognized as a syndrome since 1986, and as with AIDS, has been found in stored blood samples dating back to the 60s. Unlike HIV, however, for FIV there's a vaccine
. Not that everyone
is excited about it.
Originally, this was to be a post intended to provide something lighter until this
appeared: In addition, over 25 large cat species including, cheetahs, lions, and panthers have their own strain of the virus. Despite similarity among these viruses, transmission among species has never been documented. Scientists think that FIV is an old virus and may be the grandfather of all immunodeficiency viruses. Comparison of its' genetic code point to a virus that is millions of years old.
Googling led to several topics.
