    Chomping on uranium

    To a chemist's eye, uranium has always looked dull. Not anymore.Natural uranium mostly occurs as an oxide. In water, the oxide readily dissolves in the form of a uranyl ion—a positively charged molecule made of one uranium and two oxygen atoms. In this respect, uranium behaves similarly to lighter metals such as molybdenum and tungsten.But while most metal oxides are highly reactive, uranyl is...

    Wake Up, Little Surfers: Riding waves toward tabletop accelerators

    Many physics discoveries of the past century have emerged from giant particle accelerators costing up to billions of dollars and sprawling over acres. Now, three independent research groups in the United States, France, and England have simultaneously passed a major milestone toward a laser-based electron accelerator that could fit inside a room and cost only a fraction of the price of a...

    Science News of the Year 2003

    Fighting off the virusesA couple of decades ago, if someone had asked whether you'd heard about "that new virus," you'd have know that they were concerned about a health threat. This year, you'd have needed to ask, "Medical or computer?" On both viral fronts, 2003 was eventful. A new viral disease emerged in China, and travelers spread it around the globe.

    A year of twists and turnsWhat the world needs, say some people, is more one-handed scientists. That way, reports would have fewer sentences starting, "On the other hand. . . ."Actually, scientists need all the hands they can muster. Most of the phenomena they investigate are so complex that even carefully designed experiments can't take into account all possible influences on the results....

    Science News of the Year 2001

    The year 2001 will be remembered sadly for a single date: Sept. 11. The horrific loss of lives to terrorism on that day overshadows all earlier events of the year. The fear instilled on Sept. 11 was soon exacerbated by bioterrorism, as anthrax spores sent through the mail caused additional deaths and provided a threat that seemed it might reach into any home or workplace. People immediately...
