Bathymetric lidars – devices that employ powerful lasers to scan beneath the water's surface – are used today primarily to map coastal waters. At nearly 600 pounds, the systems are large and heavy, and they require costly, piloted aircraft to carry them.
The U.S. Department of Energy has issued a Preliminary Notice of Violation (PNOV) to Stanford University (Stanford) for four violations of the Department's worker safety and health regulations. Worker safety is a priority for the Department, and its enforcement program supports this priority by holding contractors accountable for meeting regulatory requirements and maintaining a safe and healthy workplace.
On Nov. 24, Carnegie Mellon University unveiled Andy, a four-wheeled robot designed to scramble up steep slopes and survive the temperature swings and high radiation encountered while exploring the moon's pits, caves and polar ice.
Somewhere between stuffing and pumpkin pie, the perfect test subject for the excimer laser was found
Scientists have discovered an invisible shield roughly 7,200 miles above Earth that blocks so-called “killer electrons,” which can fry satellites and degrade space systems during intense solar storms.
Berkeley Lab astrophysicist David Schlegel weighs in on Hollywood science and untapped concepts for future sci-fi flicks.
Check out the the winning images to the data visualization contest sponsored by the Health Sciences Center for Computational Innovation (HSCCI).
A new model suggests volcanic activity in Mars’ distant past spewed enough greenhouse gases to warm the atmosphere and melt the ice.
Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions.
Last year CERN announced the finding of a new elementary particle, the Higgs particle. But maybe it wasn't the Higgs particle, maybe it just looks like it. And maybe it is not alone.
A forthcoming neutrino detector will require temperatures approaching absolute zero.
