CWmike writes "A new study warned this week that DDoS attacks launched against sites run by human rights and dissident media groups threaten to knock free speech off the Web. The study, conducted by Harvard University's Berkman Center for Internet & Society, showed that such attacks frequently knocked such sites offline. Of the sites surveyed by the center, 62% were victimized by DDoS attacks in the last 12 months, and 61% experienced unexplained downtime."

SUNSTOP writes to tell us that a relatively unknown Maryland scientist has proposed a public patent that he claims could combat global warming. The proposed plan would require massive amounts of water to be sprayed into the air in an effort to bolster the earth's existing air conditioning system. "First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation. Kenneth Caldeira, a climate scientist for the Carnegie Institution's Department of Global Ecology at Stanford University whose computer simulation of Ace's invention suggests it would significantly cool the planet. The simulated evaporation of about one-half inch of additional water everywhere in the world produced immediate planetary cooling effects that were projected to reach nearly 1 degree Fahrenheit within 20 or 30 years, Caldeira said."

Ponca City, We love you writes "A study has confirmed that many people see human facial features in the front ends of automobiles and ascribe various personality traits to cars. Forty study participants assessed cars based on a system known as geometric morphometrics by viewing high-resolution, 3D computer reconstructions and printed images of 38 actual 2004-06 car models and rating each model on 19 traits such as dominance, maturity, gender, and friendliness, and if they liked the car. Study participants liked best the cars scoring high in the so-called power traits — the most mature, masculine, arrogant, and angry-looking ones. Researchers theorized that over evolutionary time, humans have developed a selective sensitivity to features in the human face that convey information on sex, age, emotions, and intentions. The lead researcher explained, 'Seeing too many faces, even in mountains or toast, has little or no penalty, but missing or misinterpreting the face of a predator or attacker could be fatal.'"

frogger writes "China is not new to censoring the Internet, but up until now, BitTorrent sites have never been blocked. Recently, however, several reports came in from China indicating that popular BitTorrent sites such as Mininova, isoHunt and The Pirate Bay had been hijacked. The sites became inaccessible, instead redirecting to the leading Chinese search engine Baidu."

Ostracus writes "Companies should not dismiss staff who use social networking sites such as Facebook and Bebo at work as merely time-wasters, a Demos study suggests. Attempts to control employees' use of such software could damage firms in the long run by limiting the way staff communicate, the think tank said."
