In the world's most expensive science experiment, 5,000 scientists, engineers and technicians from nearly three dozen countries will attempt to test the Big Bang theory to understanding the beginning of time. The tests, to re-create what happened immediately after the Big Bang, will be conducted using the Large Hadron Collider (LHC), located underneath the French-Swiss border, in the European Organization for Nuclear Research laboratory -- better known by its French acronym CERN.

Sharing a similar name with 20,000 other names of Americans on the terrorist watch list is causing nightmares to the namesakes, including children, who have been detained and questioned. Federal agencies and airlines said they are fixing the problem of false positives through the Secure Flight program, but it has been delayed because of concerns that the federal government will gain access to passenger manifests ahead.

It takes nine pounds of butter to make a gallon of biodiesel and New York State Fair officials say they will turn a 900 pound butter sculpture into 96 gallons of biodiesel fuel when the fair is over. The butter sculpture was a tribute to New York state dairy farmers and was set up as a centerpiece at the fair. SUNY College of Environmental Science and Forestry college scientists will make the butter into biodiesel at a facility on campus and use it to fuel their vehicle fleet.

The government of Canada's Manitoba province is offering local homeowners and homebuilders cash, tax credits, refunds and grants if they use geothermal energy in homes and buildings. Minister of Science, Technology, Energy and Mines Jim Rondeau announced the incentives for Manitobans as part of a national program to reduce Canada's greenhouse gases and reduce energy bills of consumers.

Scientists at the University of California, Berkeley, have been able to hide three-dimensional objects by using artificially engineered materials that redirected lights around the object. The discovery is one step closer to hiding people and objects from visible light. The researchers, led by Xiang Zhang, used metamaterials that deflected light, radar or other waves around an object such as water flowing around a smooth stone in a river.
