Cade's lithium: an extraordinary experiment with a not‐so‐ordinary element

A new Chromium-Lithium experiment

The authors present here PoLiChroM, a newly created experimental platform for the production of a novel ultracold mixture of fermionic atoms of Chromium 53 and Lithium 6, with which to investigate two paradigmatic but antithetic manifestations of strong interaction among fermions: exotic superfuidity, which arises in presence of attractive interactions that pair up fermions with opposite spins,...

Animal Rights Consideration is a Necessity in Conducting an Experiment

Mitochondrial uncouplers with an extraordinary dynamic range.

We have discovered that some weak uncouplers (typified by butylated hydroxytoluene) have a dynamic range of more than 10(6) in vitro: the concentration giving measurable uncoupling is less than one millionth of the concentration causing full uncoupling. They achieve this through a high-affinity interaction with the mitochondrial adenine nucleotide translocase that causes significant but limited...

Toward a 10,000-element B-Mode Experiment

In this paper, we introduce two compact, large-throughput CMB polarimeter designs (POLAR1 and BICEP3). These pathfinder experiments will pave the way for a comprehensive multi-frequency South Pole B-mode survey that, when jointly analyzed with arcminute-scale polarization data, can conclusively answer the question whether there is an appreciable fraction (> 1%) of the primordial perturbations i...

An extraordinary case of syphilis presenting with a labial ulcer

In the differential diagnosis of patients with ulcers on the lips characteristics like the duration of the ulcer, number, size, depth, shape, base, margins, and distribution are considered. Such ulcers arise from many diseases particularly, viral and bacterial infections, malignancies can also be responsible. Classic syphilitic chancres are painless erosions settled on hard papule; these are ev...
