Centuries-old trees may be at risk of climate change death
Giant trees in tropical forests, witnesses to centuries of civilization, may be trapped in a dangerous feedback loop, according to a new report. The biggest trees store half of the carbon in mature tropical forests, but they could be at risk of death as a result of climate change—releasing massive amounts of carbon back into the atmosphere.

Researchers aim to reduce emissions of process which feeds 40% of the world
A new research project is setting out to investigate how to make an industrial process which helps feed nearly half the world's population more sustainable. The Haber-Bosch process, developed in the early 20th Century, was the first economically-viable large-scale ammonia production process. It works by combining nitrogen and hydrogen under high pressures, with the addition of an iron-based catalyst which helps the process work at a moderate temperature.

Scientists zero in on the role of volcanoes in the demise of dinosaurs
Scientists zero in on the role of volcanoes in the demise of dinosaurs
Researchers have uncovered evidence suggesting that volcanic carbon emissions were not a major driver in Earth's most recent extinction event. Even though volcanic carbon emissions alone couldn't have triggered the mass extinction, our data highlights their influence on our planet's climate and habitability Sally Gibson Earth has experienced five major extinction events over the last 500 million years, the fifth and most recent responsible for wiping out the dinosaurs 66 million years ago.

Oxford University researchers release cheap, quick COVID-19 antibody test
The new easy-to-produce test detects coronavirus spike-protein binding antibodies in people who have tested positive for COVID-19. An international research team led by Oxford University scientists has developed a portable test for antibodies that fight the novel coronavirus that causes COVID-19. The test, which spots the presence of virus-fighting antibodies rather than a coronavirus infection, can be adapted to work on blood from a finger prick - making it quick and easy to use.

Teens ignore advice, but only when they know better
Teenagers are more likely than younger children to ignore advice, but only when the advice is bad, because adolescents are better at judging their own decisions, finds a new study led by UCL researchers. The researchers found that between the ages of nine and 12, young people improve their ability to make decisions independently by learning when they should or shouldn't trust their own judgements.
