If dark matter is made of weakly interacting massive particles (WIMPs), the possibility arises that WIMPs could collide and annihilate, emitting high-energy gamma rays in the process. The likelihood of such collisions is tiny, except in high concentrations of mass, like the vicinity of black holes. Just what the gamma-ray emission from the collisions would look like is the subject of this short video. ... See MoreSee Less

A new computer simulation tracking dark matter particles in the extreme gravity of a black hole shows that strong, potentially observable gamma-ray light can...

TRANSCRIPTION: CHROMATIN REMODELING + MANIPULATION OF THE NUCLEOSOME (DNA/HISTONE COMPLEX) *****

►"...BAF BLOCKER: In normal embryonic stem cells (top panel), the chromatin remodeling complex esBAF moves nucleosomes into enhancer-flanking DNA regions (blue) to keep enhancers (red) free of nucleosomes so they can promote transcription of protein-coding genes. When esBAF is absent (lower panel), nucleosomes move out of the flanking regions and into the enhancer, freeing up noncoding RNA transcription that begins in the enhancer and continues into the flanking DNA..."
►"...Recent genome-sequencing work has revealed that enhancer regions not only promote the transcription of protein-coding genes, but can also contain the script for noncoding RNAs. Although noncoding RNAs are a hot topic, how they are regulated isn’t understood, says Toshio Tsukiyama of the University of Washington...."

Optogenetics: Tool to control Cellular processes

Using the strategy of ex novo coupling of sensors to pores, a synthetic blue-light-gated potassium channel 1 (BLINK 1) was engineered, creating a control mechanism through which cell membrane potential can be manipulated and cell processes can be regulated.
