Stereotactic radiosurgery for craniopharyngioma management

Craniopharyngiomas are managed effectively with stereotactic radiosurgery (SRS), which provides high-dose radiation to tumors while minimizing risks to surrounding tissues. Studies have shown comparable control rates to conventional radiotherapy, but SRS is associated with lower incidence of hypothalamic obesity and long-term sequelae.

Why top firms paradoxically fire good workers

Top firms paradoxically fire good workers to maintain reputation and boost profits. Workers accept lower pay temporarily to signal elite status, while those who stay earn higher fees directly from clients. The firm's strategic underpayment of better workers increases profits by creating a stable equilibrium.

People in isolated cities in Africa suffer more violence against civilians

A new study by Complexity Science Hub researcher Rafael Prieto-Curiel challenges the assumption that larger cities are more violent. The study shows that isolated cities, with limited highway connections, experience nearly seven times more violence against civilians per 100,000 residents than well-connected cities.
