19 August 2025 World Humanitarian Day (WHD), established after the 2003 Canal Hotel bombing in Iraq, honours the courage of humanitarian workers who risk their lives to save others. This year, in the region where WHD began, the Eastern Mediterranean faces some of its darkest humanitarian crises. Humanitarian needs have never been greater, yet funding has fallen to historic lows. Aid workers now face impossible choices over who receives help and who is left behind. This must change—urgently, before it is too late.

Almost 80 per cent of attacks reported in 2025 occurred in the occupied Palestinian territory, while almost 90 per cent of all deaths occurred in Sudan. Aid workers in Afghanistan, Iran, Lebanon, Somalia, and Syria and Yemen have also been targeted and killed this year. Dozens of aid workers in Yemen continue to be arbitrarily detained, including one WHO staff member. We call for their unconditional and immediate release. Just weeks ago, WHO staff and their families in Gaza were subjected to humiliating treatment and forcibly evacuated from our staff housing in Deir al-Balah. One staff member remains detained―we demand his immediate release. I want to acknowledge the extraordinary bravery of health and humanitarian workers across the Region who continue to deliver lifesaving Read more...

Conventional wisdom among neuroscientists suggests that the brain's motor functions are organized around the body, meaning certain brain areas control the hand; others the foot. An emerging alternative theory is that parts of the brain may be organized by the types of action, like reaching or using tools, no matter which body part is used to complete the task.

Self-harm in young people is a major public health concern, rates are rising, and the adolescent years present a critical period of intervention. Another modern challenge facing adolescents is sleep deficiency, with global reductions in total sleep time and inconsistent sleep patterns, and as many as 70% of teenagers getting inadequate sleep.
