Journal Club posts are short news stories featuring a recent important, timely journal article selected by one of our Journal Club panelists, who are post-doctoral associates and graduate students in ...

Einstein’s version of dark energy is known as the cosmological constant. It implies a fixed amount of dark energy in each ...

Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a large, long-term (7-y) soil-warming study ...

Formation of knots in mathematical self-avoiding random walks has been extensively studied (10 – 16). In the 1960s, Frisch and Wasserman (10) and Delbruck (11) conjectured that the probability of ...

We present a simple nitrogen (N) isotope model to investigate the partitioning of gaseous (fgas) vs. leaching (fleaching) pathways of N removal from the nonagricultural (i.e., unmanaged) terrestrial ...

Electronic databases, from phone to e-mails logs, currently provide detailed records of human communication patterns, offering novel avenues to map and explore the structure of social and ...

Open in Viewer (A) Schematic of a photocell consisting of quantum dots sandwiched between p and n doped semiconductors. Open circuit voltage and solar photon energy ℏνh are related by the Carnot ...

Abstract Extracellular redox-active compounds, flavins and other quinones, have been hypothesized to play a major role in the delivery of electrons from cellular metabolic systems to extracellular ...

We introduce a technique to filter out complex data sets by extracting a subgraph of representative links. Such a filtering can be tuned up to any desired level by controlling the genus of the ...

Global mean temperature at the Earth's surface responds both to externally imposed forcings, such as those arising from anthropogenic greenhouse gases, as well as to natural modes of variability ...
