IBM scientists in Switzerland say they've become the first researchers to obtain a high resolution image of the chemical structure of an individual molecule. The scientists said they achieved the unprecedented resolution using non-contact atomic force microscopy, marking a milestone in surface microscopy and advancing exploration of electronic building blocks on the ultimate atomic and molecular scale. Although progress has been made in the characterization of nanostructures on the atomic...

A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). Optical and electronic properties of small assemblages of atoms called quantum dots depend upon their electronic structure "“ not just what's on the surface, but also what's inside. While scientists can calculate the...

Former U.S. Secretaries of State Warren Christopher and James Baker announced a bipartisan plan Tuesday to revise the War Powers Resolution of 1973. Writing in the New York Times, Christopher and Baker called the 1973 resolution ineffective at best and unconstitutional at worst. They said that presidents have simply ignored the resolution, which was intended to limit their power to send U.S. troops into battle without consulting Congress. Baker and Christopher suggested an alternative...

WEST LAFAYETTE, Ind. "“ Biologists at Purdue University have determined the combined structure of a common-cold virus attached to a molecule that enables the virus to infect its host, information that ultimately may help researchers develop methods for treating certain viral infections. Coxsackievirus A21 infects host cells first by recognizing a "receptor molecule" called ICAM-1, which is located on the cell's surface, and then by anchoring itself to the molecule. ICAM-1 stands for...
