Approximately 400,000 years ago, some areas of Greenland that are now covered by a thick layer of ice were exposed to fresh air and sunlight. Today, the Greenland Ice Sheet covers most of the land mass, but the southwestern coastline is ice-free. Back then, the northwest was too.
When Cop30 convened in Belém, deep inside the Amazon, the world's attention turned once again to negotiations, emissions pledges and political maneuvering. The global stage was set against one of Earth's most biodiverse landscapes and some of its most vulnerable communities,

Unexplained gamma ray radiation coming from the edge of the Milky Way galaxy could be produced by self-annihilating dark matter particles – but the idea requires further investigation
School violence is a global public health phenomenon. This is when learners and teachers are the victims of physical and psychological abuse, cyber threats and bullying, fights, gangsterism, and the use of weapons at school.
In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. Nearly 100 years later, NASA's Fermi Gamma-ray

The laws of thermodynamics don't accurately account for the complex processes in living cells – do we need a new one to accurately measure the ways living systems are out of equilibrium?
At the UN climate conference Cop30 in Belém, Brazil, I asked some young climate activists and negotiators about their hopes, expectations and demands. Despite their positivity and the push for action from climate movements, Indigenous people and civil society, a lack of
Calorie labels on menus are meant to help people make healthier choices when eating out. However, calorie information only influences people who are already actively trying to lose weight, according to a new study from the University of Surrey. For everyone else, the labels
Globalization, migration, climate change and war—nation states are currently under huge pressure on many fronts. Understanding the forces that initially drove the emergence of states across the world may help explain why.
A new report from social mobility charity the Sutton Trust shows that children from poorer families are more likely to have special educational needs. It also shows that children from wealthier families who have some kind of special educational need are more likely to get
