On the night of October 5-6, 1923, Carnegie astronomer Edwin P. Hubble took a plate of the Andromeda Galaxy (Messier 31) with the Hooker 100-inch telescope of the Mount Wilson Observatory. This plate, ...

Jesse Reimink will present his lecture in the Greenewalt Lecture Hall at Carnegie's Broad Branch Road Campus. Coffee, tea, and a light breakfast will be served before the lecture, at 10:30 a.m.

Jason Kalirai, an associate astronomer at Space Telescope Science Institute, will give a talk titled "Stellar Astrophysics: 100 Years after Russell" at 11 a.m. on Thursday, January 19, 2017, in the ...

Over the course of the last decade as a graduate student and postdoc, I developed an approach to studying drugs called evolutionary pharmacology. Last year I left academia in the face of postdocalypse ...

Stomatal guard cells develop in the epidermis of plants and surround stomatal pores that can reversibly open and close to regulate both carbon dioxide uptake for photosynthesis and water loss to drive ...

Lineage-specific stem cells are critical for the production and maintenance of specific cell types and tissues in multicellular organisms. In Arabidopsis, the initiation and proliferation of stomatal ...

Andrew Smye, assistant professor of geosciences at Penn State, will give a talk titled "Mineral-scale constraints on the geodynamics of continental extension" at 11 a.m. on Thursday, June 8, 2017, in ...

Tubulins are a conserved superfamily of proteins that are important in the structure and function of the microtubule cytoskeleton. We have characterized in vertebrates the final member of the tubulin ...

Decades of study of arc volcanism have led to a plethora of models to account for global and local observations of arc magma chemistry. Perhaps the most obvious first-order observation is that ...

Diverse microbes cause plant disease, and plants have evolved a robust innate immune system that recognizes pathogen molecules and then activates defense. Immunity involves cell surface receptors and ...

Dennis Geist, of the National Science Foundation, will present a lecture at 11 a.m. EDT on Mar. 8, 2018, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series. Coffee, tea, and a light ...

We studied the biogenesis of the autophagosome membrane by examining an early covalent event in autophagy, the lipidation of a cytosolic protein, LC3-I to form LC3-II. Using membranes from a cultured ...
