A Tutor Half a World Away, but as Close as a Keyboard  - NY Times  A few minutes before 7 on a recent morning, Greeshma Salin swiveled her chair to face the computer, slipped on her headset and said in faintly accented English, "Hello, Daniela." Seconds later she heard the response, "Hello, Greeshma." The two chatted excitedly before Ms. Salin said, "We'll work on pronouns today." Then she typed in, "Daniela thinks that Daniela should give Daniela's horse Scarlett to Daniela's sister." "Is this an awkward sentence?" she asked. "How can you make it better?" Nothing unusual about this exchange except that Ms. Salin, 22, was in Cochin, a city in coastal southern India, and her student, Daniela Marinaro, 13, was at her home in Malibu, Calif. Ms. Salin is part of a new wave of outsourcing to India: the tutoring of American students. Twice a week for a month now, Ms. Salin, who grew up speaking the Indian language Malayalam at home, has been tutoring Daniela in English grammar, comprehension and writing. Companies like Growing Stars and Career Launcher India in New Delhi charge American students $20 an hour for personal tutoring. 
Ice belt 'encircled Mars equator'  - BBC  Europe's Mars Express probe may have found evidence for a band of ice that once spanned the Martian equator. A frozen sea and patterns of glacial activity on the planet may be a relic of this ancient belt of ice, says a top scientist. The ice may have formed just before five million years ago due to a change in the tilt of Mars. This change caused moisture from the poles to be deposited as snow at the equator. It is also possible that water trapped in the Martian tropics since ancient Noachian times was mobilised around five million years ago. Another line of evidence from Mars Express is the possible discovery of a frozen sea in the Elysium region, near the Martian equator. The finding was announced by Dr John Murray of the Open University in Milton Keynes earlier this year. The sea, which would have been about the size of the North Sea and about 45m deep, froze as pack ice and was covered over as a layer of dust, the researchers said. Intriguingly, the best estimate of its date comes out at about five million years

Embryo with two mothers approved  - BBC  UK scientists have won permission to create a human embryo that will have genetic material from two mothers. The Newcastle University team will transfer genetic material created when an egg and sperm fuse into another woman's egg. The groundbreaking work aims to prevent mothers from passing certain genetic diseases on to their unborn babies. Studies in mice show it is possible to prevent the transmission of mitochondrial disease by moving the pronuclei - the genetic material which will go on to form a nucleus - from a fertilised egg containing bad mitochondria and putting it into another fertilised egg which only contains good mitochondria.
