'Employees do not give up their expectation of privacy when they come to work': arbitrator A municipal employer is allowed to pull security footage from a nearby restaurant to investigate its own staff, and it does not have to warn workers it holds that video before questioning them, according to an arbitrator.

This microfluidic device squeezes mouse skin cells as they pass through, loosening their tightly packed DNA so CRISPR tools can reach and switch on genes to make cell reprogramming more efficient. Credit: Song Li Lab/UCLA Human cells hold about two meters (6.6 feet) of DNA, folded and compacted to fit inside a nucleus. That packing is essential for life, but it creates a problem for scientists. Some of the genes that control a cell's identity are buried so deep in tightly packed DNA that gene-targeting tools such as CRISPR activation, or CRISPRa, struggle to reach them.
