The Myths and Realities of Synthetic BioWeapons

The dominant narrative permeating scientific and policy discussions on the security threat posed by synthetic biology can be summarized in five ways: Synthetic biology is making it easier for non-experts to manipulate dangerous pathogens and, therefore, making it easier for terrorists to concoct bioweapons.

Video: Ocean Acidification Masking Sharks’ Sense of Smell

Smooth dogfish (Mustelus canis). Acidic seawater has been found to impact their sense of smell. (Photo: EricksonSmith / Flickr Creative Commons) Ocean acidification is already making it harder for fish to find friends, for corals to grow, and for mussels to remain attached to hard surfaces, just to name a few effects. read more

East African Evidence for Pliocene Neogene Millenial-scale Climate Variability

East African lake evidence for Pliocene millennial-scale climate variabilityAuthors:Wilson et alAbstract:Late Cenozoic climate history in Africa was punctuated by episodes of variability, characterized by the appearance and disappearance of large freshwater lakes within the East African Rift Valley.

Hubble Observations of Titan's Atmosphere

HST observations of the limb polarization of TitanAuthors:Bazzon et alAbstract:Titan is an excellent test case for detailed studies of the scattering polarization from thick hazy atmospheres. We present the first limb polarization measurements of Titan, which are compared as a test to our limb polarization models. Show More Summary

Tutorial 28: how to remember the branches of the internal iliac artery

  Here’s a thing I put together to help my students understand the many branches of the internal iliac artery in humans. In the image above, we’re looking in superomedial view into the right half of the sacrum and pelvis. Bones are white, ligaments blue, the piriformis muscle sort of meat-colored, and arteries red (for […]

“In situ studies of the impacts of ocean acidification: observations, CO2 vents, and FOCE experiments”, 2015 Aquatic Sciences Meeting, 22-27 February 2015, Granada, Spain

The abstract submission deadline is 23:59 U.S. Central Daylight Time on Friday, 10 October 2014. Much of our understanding of the consequences of ocean acidification for marine and freshwater organisms derives from laboratory studies on single species. While this approach will continue to be essential, in situ studies evaluating the response of multispecies assemblages and […]
