Unlocking the mystery behind blood clots
An activated human platelet, a blood-clotting cell that plays a crucial role in preventing bleeding, but when overactivated can play a role in cardiovascular diseases such as heart attack and stroke. New research identifies one of the main mechanical mechanisms of blood clotting. Credit: Lining Arnold Ju (University of Sydney) and Qian Su (University of Technology Sydney).
New sensor detects rare metals used in smartphones
A new sensor changes its fluorescence when it binds to lanthanides (Ln), rare earth metals used in smartphones and other technologies, potentially providing a more efficient and cost-effective way to detect these elusive metals. Credit: Cotruvo Lab, Penn State

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.
