How changing L.A.’s tree rules could cool more neighborhoods

A new study suggests that easing L.A.'s outdated tree planting rules could significantly grow the city's urban tree canopy without compromising safety. By relaxing restrictions near intersections, utility poles, gas lines, and other infrastructure, tree coverage in lower-income neighborhoods like Boyle Heights could increase by up to 26%.

Even in egalitarian Sweden, a "culture of silence" may prevent university staff and students from reporting sexual harassment

A study at a Swedish public university found that only 8.1% of students who experienced rape or attempted rape reported the incident, highlighting a 'culture of silence'. The low reporting rate is attributed to factors such as social norms and fear of retaliation, sparking concerns over the effectiveness of reporting mechanisms.
