Female World Leaders - Which countries have had female heads of government or state so far?
This map gives a neat overview. South America, South Asia, South East Asia and Northern Europe stand out as remarkable regions. But it is also worth noting that e.g. Muslim countries have had female heads of state, when the supposedly gender equal, post-feminist US has not.

- Dark Pink - full-term heads of government or state (any point in modern history)

Wire Bonsai by Ken To
Bonsai is a reflective art, but you could almost see yourself in the delicately wrapped copper wire that Ken uses to cnstruct his miniature bonsai sculptures, which are available to purchase at his rondei.

Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees. The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.
Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.
Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.

Teacher turnover is incredibly high for [Teach for America] teachers. A report from the Great Lakes Center, a group that researches education, found that more than 50 percent left the profession after two years and more than 80 percent left after three years. This may be good for schools who are looking for cheap and transient labor, but not so for students who would benefit from having a higher proportion of experienced teachers.
There is also something uncomfortable about an organization that sends mostly white (about 61 percent, according to TFA’s website), energetic and under-qualified teachers into high-need schools with the belief that they are going to change lives."
Finally! A black hole that you can visit and survive!
Want a trip through a black hole without having to experience that pesky death? You’re in luck. There’s a special kind of black hole that’s not just survivable, but might get you to another time, or another universe.
Black holes are, traditionally, the scariest things in the universe. Huge, mysterious, inescapable, they wander through the universe and eat everything that gets too close. “Too close” is defined by their event horizon. This is the point at which they go dark, because it requires so much energy to escape them that not even light can get away. Since not even a photon can cross the barrier, no event that happens inside the horizon can ever have an effect on people outside.
Unless, something very odd was going on in the center of the black hole. Most black holes spin - this is something that was discovered way back in the 1960s by physicist Roy Kerr. It wasn’t exactly a shock, because most of the material that collapses into a black hole was already spinning. Sometimes, however, the spin on Kerr black holes goes a little above and beyond. Ever spun a glass of water, or soda bottle, so that the liquid inside swirls? Sometimes, if you spin it enough, the liquid actually parts, leaving a clear center and a spinning ring of water around it. The same kind of thing can happen in Kerr black holes. Instead of a singularity at the center, there’s a ring. And you can go through the open portion of that ring without touching the gravitational crush.
What’s on the other side? A lot of people have wondered. Some people think that these kind of black holes might be our key to time travel. They might be wormholes that let us hop between different points of the universe. Or they might be portals to different universes entirely. First we’ll have to find a few, and then we’ll need a few volunteers to go through. Preferably ones that haven’t seen Event Horizon.
