Tabouli and Baba Ganoush, the first cats produced using chromatin transfer (CT), the most advanced cloning technology, will a ppear at Genetic Savings & Clone’s exhibit at WIRED NextFest, billed as the “World’s Fair” of technology, in Chicago June 24-26. The famous cats, which were born to different surrogate mothers, turn one year old on June 12 and 14.

Invitation-only exhibitors at WIRED NextFest, hosted by WIRED Magazine, represent the best in emerging technology. Pet cloning, which GSC began offering to clients in 2004, is “the ultimate luxury service for discriminating pet lovers,” said GSC CEO Lou Hawthorne.

“The milestone of this first birthday is a strong indicator of the positive health results we’ve achieved with chromatin transfer,” said Chief Scientific Officer Phil Damiani.

The Sausalito, California-based company produced Tabouli and Baba Ganoush using a skin cell taken from Tahini, a sleek Bengal cat that belongs to Hawthorne’s five -year-old son. The company offers cat clones on a limited basis to an upscale clientele.

The clients who have received cat clones from GSC have expressed great satisfaction with the strong degree of physical and behavioral resemblance between their new cats and the “original” cats (officially termed “genetic donors”).

Best inventions of 2005

It’s imagination that makes the worm colourful and people have neve r stopped trying to turn dreams into reality. Among the thousands of inventions coming out every year, which ones are the most amazing?

Time magazine with the US said last week that Snuppy, the first cloned dog, is the most amazing invention of 2005.

The five-month-old Afghan dog was cloned at Seoul National University in South Korea by a 45-person team led by Professor Woo Suk Hwang. Snuppy ’s genes (基因) come from a single cell taken from the ear of an adult Afghan; rather than the egg (卵子) and sperm (精子) of a mother and father.

The technique used to create Snuppy is the same technique British researchers used to create Dolly the sheep, the world’s first cloned mammal .

Time selects inventions each year they believe may have a huge impact (影响) on people’s lives.

Other inventions listed in the magazine include a bicycle with a hydrogen-powered (氢动力) engine, a one-use video camcorder (可携式摄像机), and a robotic cat that recognizes speech commands.

Let’s take a closer look at some other great inventions of 2005:

Ever wonder why you feel more tired some mornings than others? It may be because your alarm went off when you were in the middle of a deep sleep.

Sleeptracker watch solves this problem by waking you only when you are in a light sleep. Equipped with a built-in sensor (内置传感器), the watch can tell whether you are in a deep or a light sleep. To ensure the best wake-up time, the watch allows a period of 20 minutes.

Sleeptracker’s alarm will go off when it senses that you are best r eady to face the day.
