From CNET:

It was inevitable that someone would seriously consider taking Google's dare.

For years, Google has all but dared traditional media companies trying to develop online businesses to live without the traffic it sends their way. The folks at the Googleplex make it clear that content owners who believe Google is unfairly indexing (or stealing, depending on your point of view) their content can easily remove that content from Google's massive corner of the Internet.

Enhancing Access to Genomic Medicine

Credit: Technology Review

From Technology Review:

A startup aims to calculate the value in the onslaught of genetic tests.

Per Lofberg wants to bring genomic medicine to the masses by overcoming one of the field's biggest barriers--getting insurers and other payers to cover the growing numbers of genetic tests reaching the market. To achieve that, he founded Generation Health, a health benefit management company that aims to sift through the data on these tests, which range from those that predict an individual's risk of heart disease or cancer to those that determine how well a patient metabolizes a certain drug. Lofberg's goal is to find the ones that provide the greatest medical utility and economic value.

Dumb Code Could Stop Computer Viruses In Their Tracks

From New Scientist:

ON THE day a new computer virus hits the internet there is little that antivirus software can do to stop it until security firms get round to writing and distributing a patch that recognises and kills the virus. Now engineers Simon Wiseman and Richard Oak at the defence technology company Qinetiq's security lab in Malvern, Worcestershire, UK, have come up with an answer to the problem.

Their idea, which they are patenting, is to intercept every file that could possibly hide a virus and add a string of computer code to it that will disable any virus it contains. Their system chiefly targets emailed attachments and adds the extra code to them as they pass through a mailserver. A key feature of the scheme is that no knowledge of the virus itself is needed, so it can deal with new, unrecognised "zero day" viruses as well as older ones.

Building a Better Alien-Calling Code

From Wired Science:

Alien-seeking researchers have designed a new simple code for sending messages into space. To a reasonably clever alien with math skills and a bit of astronomical training, the messages should be easy to decipher.

As of now, Earthlings spend much more time searching for alien radio messages than broadcasting news of ourselves. We know how to do it, but relatively little attention has been paid to “ensuring that a transmitted message will be understandable to an alien listener,” wrote California Institute of Technology geoscientist Michael Busch and Rachel Reddick, a Stanford University physicist, in a study filed online Friday on arXiv.

From Live Science:

Full-color displays for e-readers could really take off soon — on the wings of butterflies.

Qualcomm MEMS Technologies new Mirasol is the first full color, video-capable display on a prototype e-reader. Built on the concept of the iridescence of a butterfly’s wing, the new technology reflects light rather than transmitting light the way LCD screens do.

The display is readable in sunlight and offers unprecedented energy savings for longer battery life. E-readers may just be the beginning for Mirasol displays as consumers seek color in every device they use, better visibility in bright light, and days or even weeks worth of battery life.

Why Do Human Testicles Hang Like That?

From Scientific America:

Earlier this year, I wrote a column about evolutionary psychologist Gordon Gallup’s “semen displacement hypothesis,” a convincing hypothesis presenting a very plausible, empirically supported account of the evolution of the peculiarly shaped human penis. In short, Gallup and his colleagues argued that our species’ distinctive phallus, with its bulbous glans and flared coronal ridge, was sculpted by natural selection as a foreign sperm-removal device. As a companion piece to that work on our phallic origins, Gallup, along with Mary Finn and Becky Sammis, have put forth a related hypothesis in this month’s issue of Evolutionary Psychology. This new hypothesis, which the authors call “the activation hypothesis,” sets out to explain the natural origins of the only human body part arguably less attractive than the penis--the testicles.

From Technology Review:

A startup says natural language processing works best with human intelligence.

Providing answers to tricky questions has become big business online. But community question-and-answer sites can get clogged up with outdated answers, and it's fiendishly difficult to create software that can automatically understand a question and provide the best answer.

Damon Horowitz, chief technology officer and cofounder of the San Francisco-based Aardvark, will outline a different approach when he speaks at the Web 2.0 Expo in New York today.

Why Kids Ask Why

From Live Science:

A child's never-ending "why's" aren't meant to exasperate parents, scientists say. Rather, the kiddy queries are genuine attempts at getting at the truth, and tots respond better to some answers than others.

This new finding, based on a two-part study involving children ages 2 to 5, also suggests they are much more active about their knowledge-gathering than previously thought.

"Even from really early on when they start asking these how and why questions, they are asking them in order to get explanations," lead researcher Brandy Frazier of the University of Michigan told Live Science.

High-Fliers Swear A 5am Start Is The Key To Success

Photo: Yawn chorus: Is 5am a productive time to begin the day?

From The Daily Mail:

But how do you do it all, I asked my high-powered friend Fiona, who had just reeled off her latest long list of projects. 'Oh, I get up at 5am,' she said. 'So by breakfast time, I've cleared emails, been through the diary and can hit the ground running.'

That did it. For years, I've heard people proclaim the advantages of early rising. Yoga teachers, life coaches and exercise gurus swear by its benefits for the body.

Over-achievers find it's the best time to get things done because their brains are fresh and ready for action.
