News of the Week
In science news around the world this week, two leaders of the collaboration that suggested that neutrinos could travel faster than the speed of light have stepped down; the National Research Council says politicians need to make "hard decisions" about priorities for water use in the California Bay delta; the U.K. Biobank is open for business; Canada's new budget will mean heightened competition for rank-and-file scientists but leaves unchanged the overall amount of money available for research grants; and the terrorism trial of particle physicist Adlène Hicheur has ended.
A sunflower is more than just a pretty face: It's a floral expression of the so-called Fibonacci sequence—1, 1, 2, 3, 5, 8, and so on, where each number is the sum of the two preceding numbers in the series. And now, a U.K.-based project is enlisting the help of gardeners around the world to help test a theory that originated with one of history's greatest mathematicians, Alan Turing.

Synthesizing more than a decade of empirical research in Chicago, Sampson argues that neighborhoods strongly influence a wide range of social phenomena (including crime, health, civic engagement, altruism, and birthrates).

A thin layer of a topological insulator grown on the surface of a superconductor is shown to acquire a superconducting gap.
Encapsulating a liquid film between two graphene layers allows the film and growing crystals from the graphene sheets to be studied at an atomic scale.
The copper contents of magmas imply that the formation of sulfide-bearing cumulates under reducing conditions is a critical step in the formation of continental crust.
The common mineral gypsum forms when nanoparticles of an undersaturated precursor phase, bassanite, self-assemble into nanorods, followed by ripening.
Analysis of meteorites shows that unprocessed material was accreted to both planets and asteroids 150 million years after the start of the solar system.
