Founded in 1903, Carnegie's former Desert Laboratory on Tumamoc Hill gave birth to the fields of plant physiology and ecology. Founded in 2002, Carnegie's Department of Global Ecology played a ...

Helium is generally understood to be chemically inert and this is due to its extremely stable closed-shell electronic configuration, zero electron affinity and an unsurpassed ionization potential. It ...

Organic carbon (OC) mineralization in freshwaters is dependent on oxygen availability near the sediments, which controls whether OC inputs will be buried or respired. However, oxygen dynamics in ...

An overriding interest in photosynthesis has propelled my wanderings from chemist to biochemist to plant physiologist and on to global topics. Equations and models have been organizing principles ...

B-type lamins, the major components of the nuclear lamina, are believed to be essential for cell proliferation and survival. We found that mouse embryonic stem cells (ESCs) do not need any lamins for ...

10.1111/j.1945-5100.2012.01357.x We review a number of constraints that have been placed on the formation of chondrules and show how these can be used to test chondrule formation models. Four models ...

Oocytes differentiate in diverse species by receiving organelles and cytoplasm from sister germ cells while joined in germline cysts or syncytia. Mouse primordial germ cells form germline cysts, but ...

A key challenge in materials discovery is to find high-temperature superconductors. Hydrogen and hydride materials have long been considered promising materials displaying conventional phononmediated ...

We developed a high-throughput methodology, termed fluorescent tagging of full-length proteins (FTFLP), to analyze expression patterns and subcellular localization of Arabidopsis gene products in ...

We report the discovery of the first candidate microlensing event to be discovered in the direction of the Galactic Bulge. The peak brightness of the candidate event occurred on June 15, 1993. The ...
