[Book Review] Beyond “publish or perish”

02-Oct-2015 | Johanna Gutlerner, Science , 2015

Experts have been debating whether we are training too many Ph.D.s for the jobs that exist for more than 40 years, but is this really the problem? While acknowledging that some reduction in the number of trainees may be necessary, Leonard Cassuto has a different solution to the glut of graduate ...


[Report] Atomically thin two-dimensional organic-inorganic hybrid perovskites

25-Sep-2015 | Letian Dou; Andrew B. Wong; Yi Yu; Minliang Lai; Nikolay Kornienko; Samuel W. Eaton; Anthony Fu; Connor G. Bischak; ..., Science , 2015

Organic-inorganic hybrid perovskites, which have proved to be promising semiconductor materials for photovoltaic applications, have been made into atomically thin two-dimensional (2D) sheets. We report the solution-phase growth of single- and few-unit-cell-thick single-crystalline 2D hybrid ...


[This Week in Science] A solution for scalable-flow batteries

25-Sep-2015 | Marc S. Lavine, Science , 2015

Author: Marc S. Lavine


[Perspective] How minerals dissolve

18-Sep-2015 | Mariëtte Wolthers, Science , 2015

During mineral growth and dissolution, material (in the form of atoms, molecules, complexes, or clusters) is transported through water to or from the mineral surface. Even in a solution that is at equilibrium with respect to a given mineral, there is transport to and from the surface. Although ...


[Report] X-ray–driven reaction front dynamics at calcite-water interfaces

18-Sep-2015 | Nouamane Laanait; Erika B. R. Callagon; Zhan Zhang; Neil C. Sturchio; Sang Soo Lee; Paul Fenter, Science , 2015

The interface between minerals and aqueous solutions hosts globally important biogeochemical processes such as the growth and dissolution of carbonate minerals. Understanding such processes requires spatially and temporally resolved observations and experimental controls that precisely manipulate ...


[Technical Comment] Comment on “Extreme electric fields power catalysis in the active site of ketosteroid isomerase”

28-Aug-2015 | Deliang Chen; Tor Savidge, Science , 2015

Fried et al. (Reports, 19 December 2014, p. 1510) demonstrate electric field–dependent acceleration of biological catalysis using ketosteroid isomerase as a prototypic example. These findings were not extended to aqueous solution because water by itself has field fluctuations that are too large ...


[Technical Comment] Comment on “Extreme electric fields power catalysis in the active site of ketosteroid isomerase”

28-Aug-2015 | Aditya Natarajan; Filip Yabukarski; Vandana Lamba; Jason P. Schwans; Fanny Sunden; Daniel Herschlag, Science , 2015

Fried et al. (Reports, 19 December 2014, p. 1510) demonstrated a strong correlation between reaction rate and the carbonyl stretching frequency of a product analog bound to ketosteroid isomerase oxyanion hole mutants and concluded that the active-site electric field provides 70% of catalysis. ...


[Review] Crystallization by particle attachment in synthetic, biogenic, and geologic environments

31-Jul-2015 | James J. De Yoreo; Pupa U. P. A. Gilbert; Nico A. J. M. Sommerdijk; R. Lee Penn; Stephen Whitelam; Derk Joester; Hen ..., Science , 2015

Field and laboratory observations show that crystals commonly form by the addition and attachment of particles that range from multi-ion complexes to fully formed nanoparticles. The particles involved in these nonclassical pathways to crystallization are diverse, in contrast to classical models ...


[Perspective] Tracking the merry dance of nanoparticles

17-Jul-2015 | Christian Colliex, Science , 2015

Nanoparticles containing a few tens or hundreds of atoms have applications in an ever-expanding range of areas, from electronics to catalysis and biological sensors. This versatility stems from the high sensitivity of nanoparticle properties to size, chemical composition, and shape, which are ...


[Report] Keeping cool: Enhanced optical reflection and radiative heat dissipation in Saharan silver ants

17-Jul-2015 | Norman Nan Shi; Cheng-Chia Tsai; Fernando Camino; Gary D. Bernard; Nanfang Yu; Rüdiger Wehner, Science , 2015

Saharan silver ants, Cataglyphis bombycina, forage under extreme temperature conditions in the African desert. We show that the ants’ conspicuous silvery appearance is created by a dense array of triangular hairs with two thermoregulatory effects. They enhance not only the reflectivity of the ...
