Immortal Line of Cloned Mice Created
Watch out, George Lucas, there’s a new attack of the clones, and these ones are furry.
Japanese researchers have created a potentially endless line of mice cloned from other cloned mice. They used the same technique that created Dolly the sheep to produce 581 mice from an original donor mouse through 25 rounds of cloning, the scientists report in the March 7 issue of the journal Cell Stem Cell.
“This technique could be very useful for the large-scale production of superior-quality animals, for farming or conservation purposes,” study leader Teruhiko Wakayama of the RIKEN Center for Developmental Biology in Kobe, Japan, said in a statement.
New UCLA-developed device transfers mitochondria into 100,000 or more recipient cells
O,.o circa 2020.
Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders.
A study, published today in the journal Cell Reports, describes how the new UCLA-developed device, called MitoPunch, transfers mitochondria into 100000 or more recipient cells simultaneously, which is a significant improvement from existing mitochondrial transfer technologies. The device is part of the continued effort by UCLA scientists to understand mutations in mitochondrial DNA by developing controlled, manipulative approaches that improve the function of human cells or model human mitochondrial diseases better.
The ability to generate cells with desired mitochondrial DNA sequences is powerful for studying how genomes in the mitochondria and nucleus interact to regulate cell functions, which can be critical for understanding and potentially treating diseases in patients.
Juno spacecraft discovers FM radio signal coming from Jupiter moon
The Juno spacecraft orbiting Jupiter has discovered an FM radio signal coming from the moon Ganymede, a finding that marks a first-time detection from the moon, according to KTLA sister station KTVX in Salt Lake City, Utah.
“It’s not E.T.,” said Patrick Wiggins, one of NASA’s Ambassadors to Utah. “It’s more of a natural function.”
Juno was traveling across the polar region of Jupiter — where magnetic field lines connect to Ganymede — when it crossed the radio source. Scientifically, it is called a “decametric radio emission.”

The Revenge: Timo Boll vs. KUKA Robot
Circa 2015
Last year, Timo Boll challenged the KUKA KR AGILUS in his area of expertise: table tennis. Now, it is up to Timo to prove his qualities in a completely different kind of duel.
The revenge is on. Man and machine are ready. The KUKA KR AGILUS and Timo Boll face each other for a new match. But this time, there are no rackets and no balls – there’s only glass.
Watch this fantastic commercial featuring two worthy opponents that both provide utmost precision, speed and flexibility.

High-Frequency Traders Push Closer to Light Speed With Cutting-Edge Cables
The cable, called hollow-core fiber, is a next-generation version of the fiber-optic cable used to deliver broadband internet to homes and businesses. Made of glass, such cables carry data encoded as beams of light. But instead of being solid, hollow-core fiber is empty inside, with dozens of parallel, air-filled channels narrower than a human hair.
Because light travels nearly 50% faster through air than glass, it takes about one-third less time to send data through hollow-core fiber than through the same length of standard fiber.
The difference is often just a minuscule fraction of a second. But in high-frequency trading, that can make the difference between profits and losses. HFT firms use sophisticated algorithms and ultrafast data networks to execute rapid-fire trades in stocks, options and futures. Many are secretive about their trading strategies and technology.
