Life in Langata

Mike arrived in Nairobi a day ahead of me and sent a text message with his new Kenyan mobile number and the number of a driver our hostess recommended. Teddy, the driver, drove me from Jomo Kenyatta International through some smoke-clouded, dusty avenues to Langata, a neighborhood in the southwest of Nairobi adjacent to Nairobi National Park. He left the pavement while my eyes popped at the small stands where people sold fruit, fried fish, tailored clothing, and added credit to M-Pesa mobile money accounts. Teddy’s car barely made it through the mudholes and dips in the dirt road but he showed no signs of worry. He pulled up outside a fairly recent-looking concrete apartment block, pictured.

Our hostess, Ruthie, is an IT manager at a bank and has hosted lots of couch-surfers before. Already at the place when Mike and I arrived was an American couch-surfer named Ric who’d been there a while. There are guards at the entrance and until Ric insisted, there was no lock on the door. That was the first hint that security here works in a very, very different way than what we’re used to.

We’ve been using the matatus to go into town and from town out to a couple of neighborhoods we’ve been frequenting: Westlands and Kilimani. Here are some matatu photos Mike took:

I am on a trip to Nairobi and the region with my friend Mike. The idea is to spend a month exploring and chasing some story ideas we lined up ahead of time and find some new ones. I’ll post some nuggets of our adventures and observations along the way. For starters here’s a snap of Dubai, draped in fog:

And here is a toilet in the Vegas of the Middle East:

On our first night in town we dined on sushi while listening to Cuban and later central African music with a Canadian colleague (whose family background is Indian) and her American colleague. As promised, Nairobi is cosmopolitan.

Ice may lurk in shadows beyond Moon’s poles

Water ice on the moon may be more widespread  than previously thought. Permanent shadows have been spotted far from the lunar poles, expanding the number of sites that would be good candidates for exploration by robotic rovers — or even for the locations of lunar bases.

Researchers have known for decades that the Moon’s poles host craters with lofty rims that shield their floors from sunlight, so searches for shadowed areas harbouring water ice have focused on the poles. But over the past few months, researchers have built a catalogue of permanently shadowed regions elsewhere on the Moon.

Machine Vision Sees Into Chickens’ Futures

A jump to the left and a step to the right are signs of healthy activity, as chicken farmers who stroll among their flocks already know. Now a team led by robotics engineer Stephen Roberts at the University of Oxford has found that patterns in the collective motion of a flock of chickens can help farmers predict disease weeks before onset. Call it a chicken time warp.

Roberts and animal-welfare researchers at Oxford first tested their pattern-detection system by asking it to warn farmers before a flock got “peckish.” That’s not a euphemism for “hungry.” Well-fed hens, it turns out, sometimes take out their worm-hunting instincts on one another. The system, which consisted of cameras recording a flock, followed by computer analysis of the footage, beat human experts at flagging the at-risk flocks before the madness took its toll [“Computer System Counters Hen Horrors,” September 2010].
