Mirror image: neurons in the brain begin to clone after reaching aSubatomic particles do it. Now the observation that groups of brain cells seem to have their own version of quantum entanglement, or "spooky action at a distance", could help explain how our minds combine experiences from many different senses into one memory.
Previous experiments have shown that the electrical activity of neurons in separate parts of the brain can oscillate simultaneously at the same frequency – a process known as phase locking

Power from renewable sources such as wind farms will be important to fight climate change. Nevertheless, the study says that even if we do everything possible to reduce emissions between now and 2050, keeping overall temperature increases below 2ºC is "barely feasible". Credit: iStockphotoWASHINGTON DC: World leaders should focus on reducing greenhouse gas emissions as much as possible over the next 40 years to avoid perilous warming, says a new study.
In the first research of its kind, analysts used a detailed energy system model to analyse the relationship between emissions levels in 2050 and chances of achieving end-of-century targets of 2 to 3ºC above the pre-industrial average.

From BBC News:The long-distance scientific recordings of the blast wave from the first hydrogen bomb test have been rediscovered in a formerly classified safe at Columbia University.
On November 1, 1952, physicists created the second fusion explosion the solar system has ever known. The first occurred around 4.5 billion years ago and ignited the ongoing fusion reaction in the sun. The second, the Ivy Mike experiment, was shorter lived and detonated on an atoll in the South Pacific. This 10-megaton blast was five times more powerful than all the explosives used in World War II combined, including the nuclear-fission bombs dropped on Hiroshima and Nagasaki.

Google integrated two of its news experiments, Fast Flip and Living Stories,Living Stories, a project developed with the New York Times and the Washington Post, is on the upper right next to Top Stories, while Fast Flip (picture above) is right down at the bottom of the page. Both experiments should now see their audiences widen considerably.
"Encouraged by the positive feedback we've received from users and partners, we decided to expose the service to more potential readers by integrating it with the US English version of Google News," software engineers Jack Hebert, Matthew Watson and Corrie Scalisi wrote about Fast Flip on the Google news blog.

A few months ago, President Obama launched the “Educate to Innovate” campaign to strengthen competency in science, technology, engineering and mathematics. During this event, some students were invited to demonstrate their robot they built as part of the 2009 FIRST Robotics competition. One of those students, Steven Harris, commented on the importance of high school robotics teams and his experience with his own team:

On Saturdays, when my brother was a member of the team at Oakton High School, I got to go to the team meetings because my father was a parent mentor for the team, helping the members of the team build and design the robots…
