Asthma Attacks Reduced in Tree-Lined Urban Neighbourhoods
and has no comments yet.
People living in polluted urban areas are far less likely to be admitted to hospital with asthma when there are lots of trees in their neighbourhood, a study by the University of Exeter’s medical school has found.

Tropical Forest Reserves Slow Down Global Warming
and has no comments yet.
National parks and nature reserves in South America, Africa and Asia, created to protect wildlife, heritage sites and the territory of indigenous people, are reducing carbon emissions from tropical deforestation by a third, and so are slowing the rate of global warming, a new study shows.

Grown-up gannets find favourite fishing grounds
and has no comments yet.
Like humans, some birds can spend years learning and exploring before developing more settled habits.A study of northern gannets has shown adults return to the same patch of sea over and over again to find food.

Low level of oxygen in Earth's middle ages delayed evolution for two billion years
and has no comments yet.
New research by the University of Exeter explains how oxygen was trapped at such low levels. Professor Tim Lenton and Dr Stuart Daines, of the University of Exeter Geography department, created a computer model to explain how oxygen stabilised at low levels and failed to rise any further, despite oxygen already being produced by early photosynthesis. Their research helps explain why the ‘Great Oxidation Event’, which introduced oxygen into the atmosphere around 2.4 billion years ago, did not generate modern levels of oxygen.

Prehistoric mega-lake sediment offers key insight into how inland regions responded to “super-greenhouse” event
and has no comments yet.
Sediment found at the site of one of the largest lakes in Earth’s history could provide a fascinating new insight into how inland regions responded to global climate change millions of years ago.A pioneering new study, carried out by a team of British-based researchers, has analysed sediments from the site of the vast lake which formed in the Sichuan Basin, in China, around 183 million years ago in the Jurassic period.

Climate Change Impairs the Survival Instincts of Fish and Can Make Them Swim Towards Predators
and has no comments yet.
Climate change is disrupting the sensory systems of fish and can even make them swim towards predators, instead of away from them, a paper by marine biologists at the University of Exeter says.Research into the impact of rising CO2 has shown it can disrupt the senses of fish including their smell, hearing and vision.

Future increase in plant photosynthesis revealed by seasonal carbon dioxide cycle
and has no comments yet.
Doubling of the carbon dioxide concentration will cause global plant photosynthesis to increase by about one third, according to a paper published in the journal NatureThe study has relevance for the health of the biosphere because photosynthesis provides the primary food-source for animal life, but it also has great relevance for future climate change.
