Smartphone Attachment Can Test For HIV In 15 Minutes 84
stephendavion writes A team of researchers from Columbia University have developed a device that can be plugged into a smartphone and used to quickly test for HIV and syphilis. The mobile device tests for three infectious disease markers in just 15 minutes by using a finger-prick of blood, and draws all the power it needs from the smartphone, Science Daily reports. The accessory costs an estimated $34 to make and is capable of replicating tests done in a laboratory using equipment that costs many thousands of dollars.
4 Wave Gliders Begin Their Autonomous Pacific Crossing Attempt 41
In 2009, an autonomous ocean glider bobbed and dipped its way across the Atlantic; now, reader cylonlover writes with word that "Four small autonomous aquatic robots have embarked on a 60,000-kilometer (37,000-mile) journey across the Pacific ocean. The Wave Gliders, built by California-based Liquid Robotics, left San Francisco last Thursday." Two of the robot craft are to head to Australia, the other two to Japan. According to the IEEE description, "Waves will power their propulsion systems and the sun will power the sensors that will be measuring things like water salinity, temperature, clarity, and oxygen content; collecting weather data, and gathering information on wave features and currents."
Thousands of Blackbirds Fall From Sky Dead 577
Dan East writes "In a fashion worthy of a King or Hitchcock novel, blackbirds began to fall from the sky dead in Arkansas yesterday. Somewhere between 4,000 and 5,000 birds rained down on the small town of Beeb, Arkansas, with no visible trauma. Officials are making wild guesses as to what happened — lightning strike, high-altitude hail, or perhaps trauma from the sound of New Year's fireworks killed them."

Astroturfing is much more akin to ADVERTISING than honest opinion. It is not individual speech, or political speech.
It is commercial speech.
A firm has been paid to sell an idea. The same way another firm has been paid to sell a bottle of shampoo.
