Following a hunch.
Scientists Sunney Xie's development of innovative technologies for single-molecule analyses caught our attention. Curious to know more, BioTechniques contacted him to find out about the ambition, character, and motivation that led to his success. What experience most defined your research focus? When I started my independent career, I embarked on single-molecule studies, which were very compell...
متن کاملDestroying the messenger
Big mammals have big (or slow) cells C ells use two basic strategies to adapt to the size of the organism in which they reside, say Van Savage and colleagues. Depending on how often they divide, comparable cells in a mouse and an elephant differ in either metabolic rate or cell volume, but usually not both. The need for such adaptation stems from simple geometry. As body volume increases, surfa...
متن کاملCan your hunch get this punch?
A 34 year-old Hispanic female with a history of nephrolithiasis presented with right flank pain and fever. A noncontrast computer tomography (CT) showed a 4.1 × 3.9 cm cystic lesion in the right kidney lower pole and a 6 mm non-obstructive renal calculus. She was treated with cephalexin for Escherichia coli (E. coli) urinary tract infection. One year later she returned to the emergency room wit...
متن کاملPermutations Destroying Arithmetic Structure
Given a linear form C1X1 + · · · + CnXn, with coefficients in the integers, we characterize exactly the countably infinite abelian groups G for which there exists a permutation f that maps all solutions (α1, . . . , αn) ∈ Gn (with the αi not all equal) to the equation C1X1+ · · ·+CnXn = 0 to non-solutions. This generalises a result of Hegarty about permutations of an abelian group avoiding arit...
