The first-ever flying drone competition “In the next few years the idea of drones will dramatically change. You no longer need a PhD... The same functions every Web programmer uses to build apps can now make drones navigate, take pictures, find people, fly through windows, play games, and so on. When the low level control of hardware comes built-in, hobbyists can focus on writing algorithms and routines." "Autonomous Flight, with a Few Lines of Javascript"

July 4, 2012 U.S. drone 'hijackings' - University of Texas professor and grad students manipulate unmanned crafts' flight paths...even able to make them land

Thousands of drones are destined for US skies. The use of drones is taking off in America. Local governments and private businesses see them as a cheap and effective way of maintaining an eye from the sky.

But will the drones be fully under their control? A college professor and his students say not necessarily.

A civilian drone aircraft was "hijacked" by Professor Todd Humphreys and his graduate students at the University of Texas at Austin. They were able to hack into the drone's GPS signals. Later, in an exercise done in conjunction with the Department of Homeland Security at White Sands, N.M., they were even able to make the drone land.  read more »

Västra Hamnen, also known as the City of Tomorrow, was transformed from a former shipyard in 2001 and is now home to 4,000 people.

Europe’s ‘First Carbon-Neutral Neighborhood’: Western Harbour
With a smart heating and cooling system and renewable energy, the city district of Västra Hamnen (Western Harbor), in Malmö, Sweden has established itself as the first carbon-neutral neighborhood in Europe, says Malmö mayor Ilmar Reepalu.

Västra Hamnen, also known as the City of Tomorrow, was transformed from a former shipyard in 2001 and is now home to 4,000 people.

The district uses an aquifer thermal energy storage system to store water collected during the summer 70 meters (230 feet) underground and pump it up with wind energy to heat the homes during the winter. The chilled water is then reused to cool buildings in the summer. “There’s no need for air-conditioners in the district,” Reepalu proudly told the audience at the Lee Kuan Yew World City Prize Forum, held during the World Cities Summit on July 2 in Singapore.  read more »

A typical ‘candidate event’ in the Higgs-hunting CMS experiment. Red lines represent high-energy proton beams while yellow lines show the tracks of particles produced in the collision.

The Higgs boson appears in a theory first fleshed out in 1964 by Peter Higgs at Edinburgh University and five other physicists. Finding the particle proves there is an energy field that fills the vacuum of the observable universe. It plays the crucial role of giving mass to certain subatomic particles that are the building blocks of matter. The Higgs field is thought to have switched on a trillionth of a second after the big bang that blasted the universe into existence. Without it, or something to do its job, the structure of the cosmos would be radically different than it is today.

So what is the Higgs boson?  read more »

Earth may be near tipping point, scientists warn
A group of international scientists is sounding a global alarm, warning that population growth, climate change and environmental destruction are pushing Earth toward calamitous — and irreversible — biological changes.

In a paper published in Thursday's edition of the journal Nature, 22 researchers from a variety of fields liken the human impact to global events eons ago that caused mass extinctions, permanently altering Earth's biosphere. "Humans are now forcing another such transition, with the potential to transform Earth rapidly and irreversibly into a state unknown in human experience," wrote the authors, who are from the U.S., Europe, Canada and South America.  read more »

For over 30 years, determined ocean defender Captain Paul Watson has saved many wildlife, from seals, whales, dolphins, to blue tuna... but his enemies are also determined, and very "powerful, most notably the government of Japan." "Save Captain Paul Watson from a politically-motivated extradition to Costa Rica where he will not receive a fair trial, nor is it likely that he would even survive jail to see the inside of a courtroom. The Taiwanese shark fin mafia in Costa Rica have made threats on Captain Watson’s life. Costa Rica is one of the world’s largest exporters of shark fins, a trade thought to be worth millions of dollars and controlled by the Taiwanese mafia. In January 2011, celebrity chef Gordon Ramsay and his TV crew were allegedly held at gunpoint and dowsed with gasoline during the filming of his documentary on the shark-finning trade in Costa Rica." Newly released video evidence from the documentary "Sharkwater" proves Capt. Watson's innocence, but he is still being extradited from Germany to Costa Rica tomorrow (Fri), May 18. Filmmaker Rob Stewart joins the global call to free Paul Watson.

Arrest of Capt. Watson lawful? A 10-year-old case: no one injured, no property damaged; "the charges were originally dropped once the authorities saw the footage (from Sharkwater Film by Rob Stewart)"?
