...ions with the DNA strands. "So it's like having a shelf full of Tinker Toys," Baker said. An array of single-functional dendrimers, such as targets, drugs, and contrast agents, and the ability to link them together quickly and easily in many different ways would enable a clinic to offer 25 different "fla...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...her oceans in turn. For example, the Larsen B ice shelf on the Antarctic Peninsula collapsed in early 2002. Roughly 500 billion tonnes of ice sheet (3,250 square kilometers, about the size of Rhode Island) disintegrated in less than a month, what scientists have called "staggering" speed. The work builds...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

... many oceanic regions, including mid-ocean fronts, shelf breaks, submarine canyons and submerged banks. "That small zooplankton are capable of remaining at a constant depth with a precision of centimeters, sometimes in the face of strong vertical currents, is incredible," said Genin. "It implies that thes...
