A Unique Tool for Live-Cell Imaging

The biomolecules human immune systems deploy to find, tag, and destroy invading pathogens are the antibodies. Their work includes binding to specific targets, called epitopes, on the surfaces of antigens, like locks to keys. Scientists have, for so many years, exploited this selective tagging mechanism in natural antibodies to engineer antibody-based probes that let them purify and study different types of proteins within cells.

How the Neurons of A Sea Slug Could Change Neurobiology Forever

It’s a common belief that when you think of neurobiology you often imagine the brain and the central nervous system one neuron at a time. And for many years, that’s exactly how researchers had to approach the larger questions. By tagging in particular neurotransmitters, that would convey the passing of one signal from neuron to neuron, researchers were able to follow the path of a signal back and forth along an axon. But now, with new imaging technology and a new model organism in mind, researchers in neurobiology are seeking new ways in which we study the brain—mapping neural circuits and their functions in great detail, on the large scale.

Not Just NASA ‘Ducks & Covers’—Comet Siding Spring

As news spread worldwide of the arrival of Comet C/2013 A1 Siding Spring, anticipated to arrive yesterday Sunday Oct. 19 just outside of Mars’ outer atmosphere, it appears that aerospace agencies invested in the red planet headed the warnings and got out of the way of the fast moving rock. Following NASA’s lead in safety protocol, intended to keep Mars orbiters functional and safe from cosmic debris, other agencies like the European Space Agency (ESA) elected to “duck and cover” behind the planet Mars and peak out only for an up-close look at the rare, passing comet.

ESA Rosetta Spacecraft Is Showing Off Its ‘Cheops’

While Rosetta mission team members are preparing to touch down on the surface for a more up-close view of the comet, Rosetta’s Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) is taking a look at the surface from afar. And in the newest batch of images sent back Monday morning, researchers have revealed a large pyramid-shaped boulder standing 82-feet-tall near the intended landing site for Rosetta’s Philae rover.
