Switzerland to buy Swedish warplanes
Switzerland is planning to replace their aging fleet of F-5 fighter jets with a smaller number of modern Swedish aircraft:
Switzerland has decided to buy 22 Swedish JAS-39E Gripen fighters to replace their elderly F-5s. The 16 ton JAS-39E is roughly comparable with the latest versions of the F-16 and is a substantial upgrade of the current JAS-39C model. The Gripen is also used by Sweden, Thailand, South Africa, Hungary, and the Czech Republic. The 39E is still in development and will eventually replace the 14 ton JAS-39C.
[. . .]
Often regarded as an also-ran in the current crop of “modern jet fighters,” the Swedish Gripen is proving to be more competition than the major players (the F-16, F-18, F-35, Eurofighter, Rafale, MiG-29, and Su-27) expected. Put simply, Gripen does a lot of little but important things right and costs about half as much (at about $35 million each) as its major competitors. In effect, Gripen provides the ruggedness and low cost of Russian aircraft with the high quality and reliability of Western aircraft. For many nations this is an appealing combination. The Gripen is easy to use (both for pilots and ground crews) and capable of doing all jet fighter jobs (air defense, ground support, and reconnaissance) well enough.
The Gripen is small but can carry up to 3.6 tons of weapons. With the increasing use of smart bombs, this is adequate. The aircraft entered active service in 1997 and has had an uphill battle getting export sales. Sweden does not have the diplomatic clout of its major competitors, so they have to push quality and service. Swedish warplanes and products in general have an excellent reputation in both categories. Nevertheless, the Gripen is still expected to lose out on a lot of sales simply because politics took precedence over performance.
Update: Yes, I caught the mis-attribution in the headline about a minute after I posted this. Sorry for the error, etc., etc., etc.
Esperanto: the easiest way to introduce a second language to children
I got interested in learning Esperanto in my early 20’s … and even though I never needed to speak the language in ordinary life, it was a very positive experience and I would recommend it to anyone as an easy way to limber up the brain for other learning tasks. It’s easy to learn, and success in learning helps to make the next learning experience a bit easier and more enjoyable.
It’s time to retire the pop-sci term “Junk DNA”
In the Wall Street Journal, Gautam Naik and Robert Lee Hotz report on the most recent discoveries about the human genome:
The new insight is the product of Encode, or Encyclopedia of DNA Elements, a vast, multiyear project that aims to pin down the workings of the human genome in unprecedented detail.
Encode succeeded the Human Genome Project, which identified the 20,000 genes that underpin the blueprint of human biology. But scientists discovered that those 20,000 genes constituted less than 2% of the human genome. The task of Encode was to explore the remaining 98% — the so-called junk DNA — that lies between those genes and was thought to be a biological desert.
That desert, it turns out, is teeming with action. Almost 80% of the genome is biochemically active, a finding that surprised scientists.
In addition, large stretches of DNA that appeared to serve no functional purpose in fact contain about 400,000 regulators, known as enhancers, that help activate or silence genes, even though they sit far from the genes themselves.
The discovery “is like a huge set of floodlights being switched on” to illuminate the darkest reaches of the genetic code, said Ewan Birney of the European Bioinformatics Institute in the U.K., lead analysis coordinator for the Encode results.
Gentrification of Brixton
The Economist looks at the demographic and social changes underway in Brixton:
A good deal has changed in Brixton, a south London district, since Eta Rodney bought her Victorian terraced house in 1980. Then many of her neighbours were, like her, Jamaican. West Indians had settled in Brixton since 1948, when some arrived on the Empire Windrush. Today many of Mrs Rodney’s black neighbours are selling up and moving out of the area, making way for predominantly white newcomers. Britain’s historic black centre is being transformed — but in an odd way.
The Afro-Caribbean population of Lambeth, the borough where Brixton is located, is estimated to have fallen by 8% since 2001 even as the borough’s overall population has risen by 9%. Interracial mixing explains only part of this: the main reason is black flight. Afro-Caribbeans have dispersed from other parts of central London too, such as Hackney and Hammersmith and Fulham. They move to escape crime, buy bigger houses and get their children into better schools — the familiar reasons people of all races head for suburbia. In the South East outside London, Afro-Caribbean numbers have jumped, albeit from a low base.

Mrs Rodney feels both pressures. Her husband would like to retire to Jamaica. She prefers Streatham, further south in London, where she could buy a palace for the money gentrifiers are keen to pay for her house, with its original cornicing and marble fireplaces. The former council house she bought under the Conservative Party’s right-to-buy scheme—“I love Mrs Thatcher, God bless her soul”—would today fetch at least 20 times what she paid.
Of course, for many of us, the name Brixton has a very Clash-y context:
