A Facebook game could help scientists find out how to protect ash trees from ash dieback, caused by infection with the Chalara fraxinea fungus.

Have you got tadpoles in your pond yet? If they lose their tails they can regrow a new one within weeks (but don’t try this at home…)

This seems to be through raised levels of reactive oxygen species, which are usually thought to be harmful, and suggests that antioxidants may not always be helpful to health. The research could be important in understanding how healing happens, and help the development of regenerative medicine. Read the research in Nature Cell Biology.

A twin study in Québec has raised the question of genetics and bullying again, with results that seem to show that relationship problems, victimization and rejection have a genetic root – but in the victims, not the bullies.

A company in Bristol has used carbon dioxide and hydrogen to make methanol, which can then be processed into petrol. They have made five litres so far.

In the 2008 Olympics, Beijing managed to reduce its carbon dioxide emissions by 24,000 metric tons per day compared with the previous year. If this could be maintained, and if other large industrial cities did the same, this could make a big impact on global warming. During the Beijing Olympics, these reductions in air pollution were associated with improvements in biomarkers of systemic inflammation and thrombosis in young people (read the abstract).

Some of the Olympic venue sites have been cleaned up using bioremediation as part of one of the world’s largest brownfield regeneration projects. Brownfield sites are previous industrial sites and include the Aquatic Centre, where the ground was contaminated with lubricating oil. The process used indigenous microbes to aerobically biodegrade the oil, supported with REGENESIS’ Advanced Oxygen Release Compound, which released oxygen over 12 months.

Today is likely to be flying ant day in the UK. The common black ant mates on the wing, and to increase the chance of finding a mate, males and new queens all hatch within a day or two of each other. After mating, the males die and the females create new colonies. It’s a feast for the birds, as well as a dramatic bit of science.

The Society of Biology is carrying out a survey – report time, date, location and weather conditions on the website to help the society learn more about the biology of ants.

In a solar eclipse, the moon’s shadow moves at up to 5000 miles an hour.

From 20 Things You Didn’t Know About… Eclipses from Discover Magazine – and there were some amazing pictures from the solar eclipse on 20 May 2012.

Some bees are genetically more likely to go to find new nest sites or new sources of food than other bees, who just go to the same old sites.
