The Boogaloo Tipping Point
O n May 29 , two federal security officers guarding a courthouse in Oakland, California, were ambushed by machine-gun fire as elsewhere in the city demonstrators marched peacefully to protest the killing of George Floyd. One of the guards, David Patrick Underwood, died as a result of the attack, and the other was wounded. For days, conservative news broadcasters pinned the blame on "antifa," the

Interfacial tuning of chiral magnetic interactions for large topological Hall effects in LaMnO3/SrIrO3 heterostructures
Chiral interactions in magnetic systems can give rise to rich physics manifested, for example, as nontrivial spin textures.

Three-dimensional chromatin interactions remain stable upon CAG/CTG repeat expansion
Expanded CAG/CTG repeats underlie 13 neurological disorders, including myotonic dystrophy type 1 (DM1) and Huntington's disease (HD). Upon expansion, disease loci acquire heterochromatic characteristics, which may provoke changes to chromatin conformation and thereby affect both gene expression and repeat instability. Here, we tested this hypothesis by performing 4C sequencing at the DMPK and HTT

Reinforcement of biophysical properties and early TCR signaling explain how redirected CD4 + T cells recognize target cells, but the transcriptional basis for their acquired antitumor function remains elusive.

Synaptic zinc inhibition of NMDA receptors depends on the association of GluN2A with the zinc transporter ZnT1

Nature Communications, Published online: 03 July 2020; doi:10.1038/s41467-020-17109-4 In mammals, DNA methylation patterns are established by two de novo DNA methyltransferases, DNMT3A and DNMT3B. Here the authors report the crystal structures of DNMT3B in complex with both CpG and CpA DNA, providing insight into the substrate-recognition mechanism underpinning the divergent genomic methylation a

Anomalous 3D nanoscale photoconduction in hybrid perovskite semiconductors revealed by tomographic atomic force microscopy
Nature Communications, Published online: 03 July 2020; doi:10.1038/s41467-020-17012-y The role of grain boundaries (GBs) in halide perovskite is an interesting topic but existing investigations are limited to the top surface. Here Song et al. employ tomographic AFM to study the buried features of grains and GBs, revealing coexistence of interconnected conducting and inert GBs.

Creativity: The science behind the madness
An all-star cast of Big Thinkers—actors Rainn Wilson and Ethan Hawke; composer Anthony Brandt; neuroscientists David Eagleman, Wendy Suzuki, and Beau Lotto; and psychologist Scott Barry Kaufman—share how they define creativity and explain how our brains uniquely evolved for the phenomenon. According to Eagleman, during evolution there was an increase in space between our brain's input and output

Neuralink (and others) claim that brain-machine interfaces can increase the bandwidth of information from brain to machine and vice versa. In what ways can this information be interpreted?
A few thoughts to hopefully clarify my confusion are (1) we can only accept a certain volume of information at any given time (2) while there is electrical activity in the brain, when we observe this, it's often related to external stimuli [of course there is activity we can observe outside of this realm to] and (3) it takes effort to actually learn / develop neural pathways that can be useful fo
