Features that make lizards sexy are resilient to stress
The blue and black badges on a male lizard’s chin and abdomen help attract potential mates and fend off competitors. A new study by researchers at Penn State reveals that low levels of stress-associated hormones do not affect badge color or behaviors used to show off badges, suggesting that these traits are resilient to stress.

Unjamming the genome after DNA damage: A gene regulatory multi-tool has yet another function
Ccr4-Not to the rescue. A) Ccr4-Not complex associates with RNA polymerase II (RNAPII) as it travels along a strand of DNA producing RNA. B) When RNAPII becomes stuck due to DNA damage, Ccr4-Not recruits factors that mark RNAPII with a small signaling molecule called ubiquitin. C) Ubiquitylation triggers degradation of RNAPII, allowing DNA repair enzymes to repair the damage and restore gene expression. Credit: Reese Laboratory, Penn State.
