Structure of Rift Valley fever protein revealed
U. MICHIGAN (US)—Researchers have solved the structure of the nucleocapsid protein from Rift Valley fever virus (RVFV), so named for the region of sub-Saharan Africa where it was first isolated with outbreaks reported throughout the African continent as well as the Middle East. Continue…

‘Spider’ molecules behave like nanorobots
CALTECH/ U. MICHIGAN (US)—Researchers have programmed an autonomous molecular “robot” made out of DNA to start, move, turn, and stop while following a DNA track. The work is a step toward developing molecular-scale medical devices that can reposition or even rebuild themselves to accomplish different tasks. (more…)

Super-heavy element 117 joins periodic table
VANDERBILT (US)—Discovery of the super-heavy element 117 provides new information about the basic organization of matter and strengthens the likelihood that still more massive elements may form an “island of stability”: a cluster of stable, super-heavy elements that could form novel materials with exotic and as yet unimagined scientific and practical applications. (more…)

Ultra-sensitive nanodevice ‘wired’ by light
YALE (US)—In the push to detect motion on the atomic level—like the spin of a single electron—researchers from Yale University have proposed using silicon-based nanocantilevers that are smaller than the wavelength of light. The novel approach employs photonic principles, eliminating the need for electric transducers and expensive laser setups. (more…)
