Irritability is one of the most common and distressing problems teenagers and their families face.

Its main symptom is an excessive reaction to negative emotional stimuli, resulting in temper outbursts and severe irritable mood.

While current treatment options such as psychotherapy and medications are helpful for some, they can be inaccessible or poorly…The Conversation (Full Story)

Anthropic, a leading AI company, recently refused to sign a Pentagon contract that would allow the United States military “unrestricted access” to its technology for “all lawful purposes.” To sign, Anthropic CEO Dario Amodei required two clear exceptions: no mass surveillance of Americans and no fully autonomous weapons without human oversight.

The very next day, the U.S. and Israel launched a large-scale offensive against Iran.

This leaves many wondering: how different would a war with fully autonomous…The Conversation (Full Story)

Leadership transitions in dictatorships can signal upheaval – for better or worse – and in Iran that moment has now arrived. The death of the supreme leader, Ali Khamenei, in a US airstrike on Tehran on February 28 marks the most consequential rupture in the Islamic Republic’s political system since 1989.

Unlike the managed transition that followed the death of Ayatollah Ruhollah Khomeini (who led the country from the 1979 revolution for ten years, after which Khamenei took over) things are different. This succession…The Conversation (Full Story)

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids, which will from now on be discovered at an astonishing rate as it begins its Legacy Survey of Space and Time, a ten-year survey probing the deepest reaches of the universe.

During the course of this survey, astronomers around the globe will seek to answer some of the most pressing questions about the nature of our world.

To the naked eye, the night sky seems like a static…The Conversation (Full Story)

After a dry 2025 with the UK’s warmest summer on record, winter 2026 delivered something very different: rain for 50 days in a row in parts of Devon and Cornwall, one of the rainiest seasons on record and only 80% of average sunshine.

Scientists have given this a name: climate whiplash.

Climate whiplash describes rapid swings from one type of weather extreme to another, most commonly from really persistent drought to really persistent wet weather. Globally, such swings have increased in recent…The Conversation (Full Story)

Three US F-15E fighter jets were shot down over Kuwait in the early hours of Monday (March 2) in an apparent friendly fire incident during Operation Epic Fury, the joint US-Israel campaign against Iran.

All six crew members ejected safely and are in a stable condition – but “safely” is a relative term when you’re being blasted out of a stricken aircraft travelling at combat speed.

Decisions to eject are not taken lightly, but often only a few seconds are available to make that call – one that…The Conversation (Full Story)
