Leading firms launch a scheme to help black and minority ethnic students get jobs as chemistry researchers.

A judge grants an 'extensive' injunction in order to prevent access without permission to HS2 land or disruption taking place to its construction.

Tax fossil fuel companies' profits to pay for the damage done by climate change, says UN Secretary General.

Oaks, maples and chestnuts found in cities are among over 1,000 tree species that are flagged at risk.

The Perseverance robot is close to completing its first set of objectives on Mars.

Heatwaves hit China, Europe and the US, causing lakes and rivers to dry up. Is this year the driest ever?

Climate change is threatening the health and survival of trees in urban areas including in Africa, with more than half of species under threat, according to a new study.
Research in the journal, Nature Climate Change says trees in cities globally are under pressure as the weather gets warmer and drier.
Trees are particularly vulnerable in countries like India, Niger, Nigeria and Togo.
Scientists want better protection of existing trees and for drought-resistant varieties to be planted.
Oaks, maples, poplars, elms, pines and chestnuts are among more than a thousand species believed to be at risk.
Trees have cooling effects and provide shade, making cities more liveable.
The researchers used the Global Urban Tree Inventory - a database recording more than 4,000 trees and shrubs planted 164 cities - to assess the likely impact of global warming.
