More than 2 billion people - one out of every four people in the world - lack fresh water. For about 733 million of them, the situation is critical. There is no one solution to this grim problem; a multi-pronged approach will be needed, and technology will play a key role in, among other things, cleaning up polluted water. Salam Titinchi outlines the role of powerful nanotechnology: carbon nanomaterials.
Countries in the drought-stricken Horn of Africa - specifically Kenya, Somalia, and Ethiopia - could use this type of technology. They’ve had five consecutive failed rainy seasons - and it’s a trajectory that looks set to continue. The east African nations now face a massive humanitarian crisis: almost 22 million people need food assistance. The effect of drought on agriculture and food supplies is well-known, but it can also put people’s health at risk through the spread of disease. Gina Charnley unpacks the four ways it can do this.

In 2022 we detailed the discovery of 1,500 stone points in France’s Madrin cave. Experiments now show that they could were used as arrowheads, pushing back evidence of archery in Eurasia by 40,000 years.

Fortunately, most of these changes are only temporary.
