Speculation continues about the crash of Air France jetliner flight 447 on its transatlantic journey. A University of Indianapolis international relations expert says recent events point to the possibility of terrorism.
Although there have been no claims of responsibility or specific indications of sabotage, the disappearance of a large airliner without warning is extremely rare and investigators say no potential causes have been ruled out. Today, aviation authorities revealed another Air France flight from Buenos Aires to Paris was grounded temporarily May 27 because of a telephoned bomb threat.

- Kar-Tel Uses RADWIN's Systems for Cellular Backhaul in the City
RADWIN (http://www.radwin.com), a leading provider of wireless broadband solutions, today announced that Kar-Tel - one of the largest mobile carriers in Kazakhstan - deployed its systems for cellular backhaul in the city of Almaty. KaR-Tel offers services in all Kazakhstan since 1999, and is a subsidiary of VimpelCom, Russia's second largest mobile operator.
Seeing the world through 'rose-colored glasses' may be more biological reality than metaphor, according to a University of Toronto study that provides the first direct evidence that our mood literally changes the way our visual system filters our perceptual experience.
The U of T team used functional magnetic resonance imaging to examine how our visual cortex processes sensory information when in good, bad, and neutral moods. They found that donning the rose-coloured glasses of a good mood is less about the colour and more about the expansiveness of the view.
An ultra-broadband, low-power radio chip, modeled on the human inner ear could enable wireless devices capable of receiving cell phone, Internet, radio and television signals. Rahul Sarpeshkar, associate professor of electrical engineering and computer science, and graduate student Soumyajit Mandal designed the chip to mimic the inner ear, or cochlea. The chip is faster than any human-designed radio-frequency spectrum analyzer and also operates at much lower power.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement—a phenomenon peculiar to the atomic-scale quantum world—in a mechanical system similar to those in the macroscopic everyday world. The work extends the boundaries of the arena where quantum behavior can be observed and shows how laboratory technology might be scaled up to build a functional quantum computer.
The research involves a bizarre intertwining between two pairs of vibrating ions (charged atoms) such that the pairs vibrate in unison, even when separated in space. Each pair of ions behaves like two balls connected by a spring , vibrating back and forth in opposite directions. Familiar objects that vibrate this way include pendulums and violin strings.
Nothing makes modern progressives happy like hoping mankind regresses and nothing makes modern conservatives happy like hoping progress in the future will clean up the environment.
Both sides may win, according to research led by Durham University. The secret of a successful sandcastle could aid the revival of an ancient eco-friendly building technique in the future. Parts of the Great Wall of China and the Alhambra at Granada in Spain were built using 'rammed earth', which means it lasts a long time and is sustainable, pleasing one side, and both of those have military applications, pleasing the other.
Sleeping pills have been associated with a four-fold increase in suicide risk in the elderly but is it just bad correlation, in that sleeping pills are just a convenient way to commit suicide? Researchers writing in the BMC Geriatrics say that after adjusting for the presence of psychiatric conditions sedatives and hypnotics were both associated with an increased risk of suicide.
Anders Carlsten and Margda Waern from Gothenburg University carried out a case control study to determine whether specific types of psychoactive drugs were associated with suicide risk in later life.
A national Radiation Therapy Oncology Group (RTOG) study led by a Medical College of Wisconsin Cancer Center physician at Froedtert Hospital in Milwaukee has found that a course of radiation therapy to the brain after treatment for locally advanced non-small cell lung cancer reduced the risk of metastases to the brain within the first year after treatment. The study was presented at the American Society of Clinical Oncology annual meeting in Orlando.
Like human infants, young apes are make noises when you tickle them. Is that really laughter? The answer to the question is yes, say researchers in Current Biology.
The researchers analyzed the recorded sounds of tickle-induced vocalizations produced by infant and juvenile orangutans, chimpanzees, gorillas, and bonobos, as well as those of human infants. A quantitative phylogenetic analysis of those acoustic data found that the best "tree" to represent the evolutionary relationships among those sounds matched the known evolutionary relationships among the five species based on genetics. The researchers said that the findings support a common evolutionary origin for the human and ape tickle-induced expressions.
