Cassini Spacecraft Captures Striking Images Of Three Saturn Moons

The jets emanate from hot fissures known as "tiger stripes" at the south pole

Cassini Spacecraft Captures Saturn Moon Geyser Images -- BBC

The Cassini spacecraft has captured striking images from flying by three moons of Saturn, including new pictures of Enceladus's gushing geysers.

Cassini made its lowest pass yet over the south pole of Enceladus, at at an altitude of 74km (46 miles).

This allowed it to "taste" the jets of water vapour and ice that the moon spews forth into space.

The Nasa probe also made relatively close flypasts of two other Saturnian satellites: Dione and Janus.

A History Of Breast Enlargements

A Brief History Of Breast Enlargements -- BBC

It is 50 years since the first breast enlargement using silicone implants. Today it rates as the second-most popular form of cosmetic surgery worldwide, undergone by 1.5 million women in 2010.

It was spring 1962 when Timmie Jean Lindsey, a mother-of-six lay down on the operating table at Jefferson Davis hospital in Houston, Texas.

Over the next two hours, she went from a B to a C cup, in an operation that made history.

"I thought they came out just perfect… They felt soft and just like real breasts," says Lindsey now aged 80.

"I don't think I got the full results of them until I went out in public and men on the street would whistle at me."

Death Of A Data Haven: Cypherpunks, WikiLeaks, And The World's Smallest Nation -- Ars Technica

A few weeks ago, Fox News breathlessly reported that the embattled WikiLeaks operation was looking to start a new life under on the sea. WikiLeaks, the article speculated, might try to escape its legal troubles by putting its servers on Sealand, a World War II anti-aircraft platform seven miles off the English coast in the North Sea, a place that calls itself an independent nation. It sounds perfect for WikiLeaks: a friendly, legally unassailable host with an anything-goes attitude.

Origins Of Domestic Cattle Traced Back 10,500 Years -- Cosmos

LONDON: All cattle are descended from as few as 80 animals that were domesticated from wild ox in the Near East some 10,500 years ago, according to a new genetic study.

An international team of scientists were able to conduct the study by first extracting DNA from the bones of domestic cattle excavated in Iranian archaeological sites. These sites date to not long after the invention of farming and are in the region where cattle were first domesticated.

Controversial Pesticide Linked To Bee Collapse -- Wired Science

A controversial type of pesticide linked to declining global bee populations appears to scramble bees’ sense of direction, making it hard for them to find home. Starved of foragers and the pollen they carry, colonies produce fewer queens, and eventually collapse.

The phenomenon is described in two new studies published March 29 in Science. While they don’t conclusively explain global bee declines, which almost certainly involve a combination factors, they establish neonicotinoids as a prime suspect.

With Google Earth No One Can Hide The Slums

With Google Earth, India Can No Longer Hide Its Shantytowns And "Slumdogs" -- Time/AP

SANGLI — Before Google Earth existed, the slums of Sangli, a city of 550,000 in southwestern India, was acknowledged on government maps by nothing more than some clumsily outlined, empty spaces. But then, from high in the sky, the eye of a satellite saw what no municipal geometer had taken the trouble to show: small islands of huts with dilapidated roofs spread throughout the city.

Thanks to the satellite images available on Google Earth, a full picture of these forgotten slums has emerged. They now have borders; they are mapped; they have an identity. And using these images, Shelter Associates, a Pune-based NGO, has begun rehabilitating the slums. For the first time in their lives, 3,900 families in Sangli are going to be moving into apartments.

Giant Solar Tornado Caught In NASA Video

Monster Solar Tornadoes Discovered -- MSNBC/Discovery News

Tempests measure width of several Earths and swirl at speeds of up to 190,000 miles

For the first time, huge solar tornadoes have been filmed swirling deep inside the solar corona — the sun's superheated atmosphere. But if you're imagining the pedestrian tornadoes that we experience on Earth, think again.

These solar monsters, measuring the width of several Earths and swirling at speeds of up to 190,000 miles per hour, aren't only fascinating structures; they may also trigger violent magnetic eruptions that can have drastic effects on our planet.

Half Of All U.S. Households Own At Least One Apple Product

The overall ownership rate is 1.6 Apple products per American household, according to a new survey.

Half Of U.S. Households Own At Least One Apple Product -- CNN

(Mashable) -- Apple has taken firm root in America. Just over half of all households in the country own at least one Apple product, a new survey says, showing just how far the reach of the company has come in the last decade.

At the turn of the 21st century, Apple was in rough shape. It had narrowly avoided bankruptcy, and Steve Jobs' return as CEO a few years earlier was turning the company around, but the market share of its products -- then almost exclusively Mac computers -- was dismal, at about 2% worldwide.

Fossil Raindrops Reveal Ancient Atmosphere -- Cosmos

BRISBANE: The fossilised marks of raindrops that fell 2.7 billion years ago in South Africa have revealed the composition of the Earth's early atmosphere.

According to a new study published in Nature today, the early Earth had an atmosphere with similar air pressure to the present day, but much higher levels of greenhouse gases. The findings, from a time when the Earth already had abundant microbial life, should improve our knowledge of what kinds of extrasolar planets might support life.

Transparent Memory Chips – The Next Step in Memory Storage -- Sci-Tech Daily

As technology moves forward, things get smaller, faster and now possibly transparent. A team of scientists have developed transparent, flexible memory chips that may one day replace flash drives and other personal data storage devices.

New memory chips that are transparent, flexible enough to be folded like a sheet of paper, shrug off 1,000-degree Fahrenheit temperatures — twice as hot as the max in a kitchen oven — and survive other hostile conditions could usher in the development of next-generation flash-competitive memory for tomorrow’s keychain drives, cell phones and computers, a scientist reported today.

Dolphins 'Resort To Rape' -- The Telegraph

Dolphins appear to have a darker side, according to scientists who suggest they can resort to 'rape' to assert authority.

Researchers found the marine mammals lead complex social lives, living in an "open society" where regular homosexual and bisexual relationships are found.

The conclusions from the international team of scientists came after they spent the past six years studying the behaviour of 120 bluenose dolphins in Shark Bay, Western Australia.

Future Wars Will Be Fought By Hackers

Richard Clarke On Who Was Behind the Stuxnet Attack -- Smithsonian

America's longtime counterterrorism czar warns that the cyberwars have already begun—and that we might be losing.

The story Richard Clarke spins has all the suspense of a postmodern geopolitical thriller. The tale involves a ghostly cyberworm created to attack the nuclear centrifuges of a rogue nation—which then escapes from the target country, replicating itself in thousands of computers throughout the world. It may be lurking in yours right now. Harmlessly inactive...or awaiting further orders.

A great story, right? In fact, the world-changing “weaponized malware” computer worm called Stuxnet is very real. It seems to have been launched in mid-2009, done terrific damage to Iran’s nuclear program in 2010 and then spread to computers all over the world.

My Comment: This is a long read .... but it is comprehensive and thoughtful. As to what is my take on the future of war .... in a way I do agree with Mr. Clark's assessment. Future wars will be fought (in some capacity) by hackers who will also have their own "army of ninjas" to use when needed.
