The EU countries have decided that the EU is to be climate neutral by 2050. By 2030, greenhouse gas emissions must have been reduced by at least 55% compared to 1990. To meet this target, continued vigorous efforts are needed to reduce emissions, but that alone will not be enough … | Continue reading
A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and the bulk metal, making them highly useful in both basic and applied research. Me … | Continue reading

Thought to make up 85% of matter in the universe, dark matter is nonluminous and its nature is not well understood. While normal matter absorbs, reflects, and emits light, dark matter cannot be seen directly, making it harder to detect. A theory called "self-interacting dark matt … | Continue reading
In many parts of Africa, humans cooperate with a species of wax-eating bird called the greater honeyguide, Indicator indicator, which leads them to wild bees' nests with a chattering call. By using specialized sounds to communicate with each other, both species can significantly … | Continue reading
How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of … | Continue reading
