A rare species of lady’s slipper orchid (Cypripedium fargesii) grows black spots that look like a fungus. But it’s not a fungus; it’s a feature, as Zong-Xin Ren of the Chinese Academy of Sciences found out during four years of research.The lady’s slippers are generally pollinated by bees but C.fargesii is different. Over many hours of observation, the only insects that Ren ever saw leaving the flowers were flat-footed flies. Ren captured four of them and when he peered at them under an electron microscope, he saw pollen grains from the orchid, and spores from a fungus called Cladosporium. This fungus infects leaves and fruits, and when it does so, it produces black mold spots. The purpose of the orchid’s black splotches was becoming clear.Like they always say, you catch more flies with fungus than with vinegar. Cypripedium fargesii is not the only orchid that attracts pollinating insects by deception, as you’ll see in the article at Not Exactly Rocket Science. The article also illustrates the importance of humorous headlines.
Ren also analyzed the orchid’s scent, an unpleasant fragrance reminiscent of rotting leaves. He found that the flower produces over 50 aromatic molecules that are found in other flowers, but three unusual ones that are common to Cladosporium molds.

It was slaughter on a huge scale. Hundreds of migrating gazelles would be funnelled into enclosures where they could be butchered en masse.More information at the link. I also found additional photos and descriptions of the structures here and here. The "technology" is quite reminiscent of the North American "buffalo jumps" (see also here), and of the ancient fishing weirs found worldwide.
It has long been suspected that the enigmatic stone structures that dot the Syrian landscape were involved in harvesting gazelles. Built perhaps as far back as 10,000 years ago, these structures display converging pairs of low stone walls.
When British air force pilots first flew over them in the early 20th Century, they dubbed them "desert kites" because of their characteristic appearance from the air...
Drs Bar-Oz, Melinda Zeder and Frank Hole describe in PNAS the discovery of a large deposit of gazelle bones at the site of Tell Kuran, near the town of Hasseke in the Khabur Basin. This killing pit is very close to a number of desert kites and contains thousands of gazelle parts. "It is manifest that these remains are from a catastrophic hunting episode - a full herd was killed," said Dr Bar-Oz...
Whereas the limited activities of ancient hunter-gatherer societies may even have nurtured herds, preventing them from getting too big and damaging the landscape, this systematic removal of whole breeding groups would have rapidly reduced gazelle numbers in the Khabur Basin.
And with kites spread right across the Near East, with large arrays in Jordan in particular, the impact on what was once an abundant wild ungulate must have been profound.

On the heels of the shocking announcement last month by Detroit public schools emergency financial manager (efm) Robert Robb to close up to eight schools and sell up to 45 schools to charter companies, he slated the highly successful and unique Catherine Ferguson academy for closure. The school, which has been featured in the film grown in Detroit documenting the school’s urban farm and in O: the Oprah Winfrey magazine, boasts a 90% graduation rate and 100% college and higher education acceptance upon graduation. The award winning school is specifically for pregnant and parenting teens and their children, offering a wide range of classes and child care. It is the only school of its kind in the nation. - Shirleyujest's diary over at the great orange Satan.



A rarity might be less popular; it might be less interesting. But it's no longer less available the way it once was. If you have a decent Internet connection and a slight cast of amorality in your character, there's very little out there you might want that you can't find. Does the end of rarity change in any fundamental way, our understanding of, attraction to, or enjoyment of pop culture and high art? ...
In a recent issue of the New York Review of Books, the poet Dan Chiasson wrote at length about Keith Richards' autobiography and made an interesting point near the end, about how scarcity and rarity, long ago, actually fueled artistic endeavor:
[T]he experience of making and taking in culture is now, for the first time in human history, a condition of almost paralyzing overabundance. For millennia it was a condition of scarcity; and all the ways we regard things we want but cannot have, in those faraway days, stood between people and the art or music they needed to have: yearning, craving, imagining the absent object so fully that when the real thing appears in your hands, it almost doesn't match up. Nobody will ever again experience what Keith Richards and Mick Jagger experienced in Dartford, scrounging for blues records.
Point taken--but let's remember it's a small sacrifice. I have this or that fetish object--the White Album on two 8-tracks in a black custom case, for example, or a rare Elvis Costello picture disc. And I remember the joy of the find. But it's hard to feel bad about the end of rarity; didn't a lot of the thrill come from feeling superior when you had something others didn't? You really want to get nostalgic about that? We're finally approaching that nirvana for fans, scholars, and critics: Everything available, all the time. (Certainly Richards and Jagger would approve.) It's not an ideal state of affairs for a rights holder, of course. But for the rest of us, what is there to complain about?
And this:The modern world bombards us with stimuli, a nonstop stream of e-mails, chats, texts, tweets, status updates and video links to piano playing cats.
There's growing concern among scientists that indulging in these ceaseless disruptions isn't good for our brains, in much the way that excessive sugar or fat - other things we evolved to crave when they were in shorter supply - isn't good for our bodies.
And some believe it's time to consider a technology diet.
Some psychiatrists worry that people are increasingly demonstrating addict-like behavior when it comes to technology, unable to ignore its pull, even when it negatively affects them.If you ever find yourself wishing you had three hands, you know you're in trouble.
Among the constantly connected, many say they suddenly lack the focus and attention span they once had. They find it harder to get through a book, movie, conversation or even article (where you going, reader?) without feeling the tug of technology.
The last of six people involved in the torture-murder of a pregnant, developmentally disabled woman in Alton, Ill., has been sentenced to 30 years in prison for first-degree murder.
Investigators have received more than 340 tips in the killing of 27-year-old Iowa real estate agent Ashley Okland, but no arrests have been made.
Sunspots are actually regions of slightly cooler material at the Sun’s surface. Hot plasma (ionized gas, stripped of one electron or more) rises from the solar interior, reaches the surface, cools off, and sinks back down. This is called convection, and is the same process you see in a pot of boiling water. But at the surface, the tortured and twisted magnetic field of the Sun can suppress convection, preventing the cooler material from sinking. Since the brightness of the plasma depends on the temperature, this cooler stuff is darker. Boom! Sunspot.
Or, in this case, sunspots. You can see five of the suckers here, changing and mutating as the plasma interacts with the magnetic field. I recognize these spots, too: they were responsible for the first X-class flare of the season on March 15th. There’s dramatic footage of that as well which I posted on my blog at the time. They’re busy spots; they blew out a lower energy flare a few days earlier, too.
And here I am calling them cute and little when they’re actually comfortably bigger than the Earth and exploded with the energy equivalent of millions — millions! — of nuclear bombs.
A man went fishing one day.
An Associated Press photographer had snapped a picture of a group of Shelties wandering the streets in Minami Soma city, an area that has been evacuated because of proximity to the Fukushima Dai-ichi nuclear complex in Japan. A team called Sheltie Rescue went into action after the picture was published, determined to bring the dogs out of the danger zone.Through emails and Internet research it was established that the owner of the dogs was a breeder in Minami Soma. The group contacted the Fukushima city branch of the Japan Collie Club, tracked the owner down by phone at a shelter and got her go-ahead to rescue the dogs.The group found the dogs waiting for their owner. A few ran off, but the group was able to remove twenty dogs from the area. Some of the dogs are being boarded at a veterinary clinic; others at the homes of volunteers.
In the wee hours of Sunday morning, seven volunteers left Tokyo and drove over broken roads and past demolished houses to meet three other volunteers in the ghost town that Minami Soma has become. Some had prepared radiation suits and others wore simple vinyl raincoats.
