Identifying factors that influence mercury levels in tuna

Most consumers' exposure to toxic methylmercury occurs when they eat fish. But research just published in the ACS journal Environmental Science & Technology could help clarify why methylmercury concentrations in tuna vary geographically.

Ecological benefits of part-night lighting revealed

Night-time pollinators benefit from street lights being switched off in the middle of the night Switching off street lights to save money and energy could have a positive knock-on effect on our nocturnal pollinators, according to new research.

Scientists identify two new species of fungi in retreating Arctic glacier

Two new species of fungi have made an appearance in a rapidly melting glacier on Ellesmere Island in the Canadian Arctic, just west of Greenland.

Fossil deposit is much richer than expected

Paleontologist at the University of Bonn analyses finds from the Dutch town of Winterswijk It has long been known that a quarry near the Dutch town of Winterswijk is an Eldorado for fossil lovers.

Newly discovered deep-sea microbes gobble greenhouse gases and perhaps oil spills, too

Newly discovered deep-sea microbes gobble greenhouse gases and perhaps oil spills, too Scientists at The University of Texas at Austin's Marine Science Institute have discovered nearly two dozen new types of microbes, many of which use hydrocarbons such as methane and butane as energy sources to survive and grow--meaning the newly identified bacteria might be helping to limit the concentrations of greenhouse gases in the atmosphere and might one day be useful for cleaning up oil spills.
