Observation of an Excited Bc+/- Meson State with the ATLAS Detector

November 24, 2014

Figure 1: Invariant mass distributions of the reconstructed Bc± → J/ψπ± candidates in 7 TeV data (top) and in 8 TeV data (bottom). The data are represented by the points with error bars (statistical only). The solid line is the projection of the results of the unbinned maximum likelihood fit to all candidates in the mass range 5620–6820 MeV. The dashed line is the projection of the background component of the same fit. [From G. Aad et al.


Lost and Found: A Science Symposium about Navigation

November 21, 2014

On November 14, 2014, experts from fields as far-ranging as human cognitive neuroscience and neural computation, animal life science, anthropology and culture, space science, current and future technology, and emergency management converged on Radcliffe’s annual Science Symposium to conduct a broad, cross-disciplinary investigation of navigation and way-finding.

A microfabricated array of TES bolometers

Figure 8:An example of a microfabricated array of TES bolometers, an 88 pixel, dual polarization TES bolometer array made at NIST for the SPTpol experiment. TES detectors are micro-machined from thin films deposited on silicon wafer substrates which means TES-based devices are fundamentally fabricated as arrays. [from K.N.

High-Z Supernova Search Team

Professor Christopher Stubbs is a member of the High-Z Supernova Search Team which, together with the the Supernova Cosmology Project, have been awarded the 2015 Breakthrough Prize in Fundamental Physics "for the most unexpected discovery that the expansion of the universe is accelerating, rather than slowing as had been long assumed."


New Nanoscale Tools for Interrogating Living Cells and Cell Networks

Nano-Bio Interfaces

Electrodes and electrode arrays capable of recording electrical signals from neurons come in an increasing number of shapes and sizes, and researchers are continuously adding capabilities. Nature Methods profiled several scientists working on new types of electrodes which are delivering ever more electrophysiological information from both intracellular and extracellular measurements, among them Prof. Hongkun Park's research group and its work on vertical nanowire electrode arrays.
