Many experienced posttraumatic symptoms. This collective trauma blurred the lines between witnesses and victims, leading to a shared experience of pain and grief across Israeli society. In the wake of these attacks, a notable phenomenon emerged: memorial tattoos reflecting personal narratives while also representing collective trauma experienced by the entire nation. A new study by researchers at Bar-Ilan University uses Terror Management Theory (TMT, Solomon et al., 1991) to explore the rise of memorial tattoos in Israel following the attacks, offers insights into how individuals cope with trauma and find meaning through tattoos, using TMT as a theoretical framework, and ultimately contributing to the understanding of psychological resilience in the face of terror.

However, in humans, most editing occurs in non-coding regions, with only a small fraction leading to changes in protein function. In contrast, in flies, the majority of rna editing events occur in sequences that directly produce proteins.

When they move, the flow of air relative to their bodies provides crucial information, complementary to their sense of balance, to perceive their own motion in space. This might explain their agility in the dark as they scurry through pipes and tunnels, turn corners, and effortlessly travel from one location to another, all while knowing exactly where they're headed.
