Demonstration of a low-frequency three-dimensional terahertz bullet with extreme brightness

Bright terahertz sources confined to diffraction-limited spot sizes are needed for nonlinear applications but focusing in this regime is challenging. Here, Shalaby and Hauri use terahertz wavefront manipulation combined with focusing optimization to achieve three-dimensional terahertz bullets.

High-performing nonlinear visualization of terahertz radiation on a silicon charge-coupled device

The absence of an imaging device in the low frequency terahertz range has hindered the advance of applications. Here, Shalabyet al. introduce a silicon based charge coupled device allowing the visualization of terahertz radiation in real time and at high spatial detail.

A magnetic non-reciprocal isolator for broadband terahertz operation

Faraday isolators prevent back reflection of light through photonic systems, and are widespread at optical frequencies. Shalaby et al. show that the permanent magnet SrFe₁₂O₁₉can be used to generate a broadband rotation with low dispersion, and build an isolator suitable for short terahertz pulses.

An optical oscilloscope for the mid-infrared

An off-the-shelf silicon image sensor can directly record few-cycle optical waveforms in the mid-infrared in a single shot by employing tunnelling ionization as a temporal gate.

MEF2B is a member of the BCL6 gene transcriptional complex and induces its expression in diffuse large B-cell lymphoma of the germinal center B-cell-like type

In this study, the authors found that the transcriptional regulator myocyte enhancer binding factor 2 B (MEF2B) is an essential component of the BCL6 gene transcriptional complex and promotes diffuse large B-cell lymphoma (DLBCL) growth by inducing BCL6 expression. In addition to its regulatory role in DLBCL growth, MEF2B expression correlates positively with BCL6 and CD10 expression, and preferentially expressed in the germinal center B-cell-like DLBCL group.
