There is evidence that some microbial life had migrated from the Earth’s oceans to land by 2.75 billion years ago, though many scientists believe such land-based life was limited because the ozone layer that shields against ultraviolet radiation did not form until hundreds of millions years later.
But new research from the University of Washington suggests that early microbes might have been widespread on land, producing oxygen and weathering pyrite, an iron sulfide mineral, which released sulfur and molybdenum into the oceans. (more…)

University of Exeter scientist Dr Fiona Mathews has discovered one of Britain’s rarest mammals living in East Devon.
Members of the public were treated to a surprise close-encounter with the Grey long-eared bat, believed to be one of only 1,000 individuals in the country, at an event organised by East Devon District Council’s Countryside Service at the Axe Estuary Wetlands.
The bat evening was part of a regular Wet and Wild Weekend – a celebration of the wildlife of the Axe Estuary Wetlands attracting nearly 500 people. Dr Mathews and fellow bat-enthusiast Adrian Bayley had set up mist nets so that people could meet some of the animals they were hearing on bat detectors, and were amazed to find the country’s rarest bat.
There are only six known breeding colonies of Grey long-eared bats in the UK. This discovery potentially links an isolated group near Newton Abbot with colonies in Dorset and the Isle of Wight. (more…)
Pancreatic cancer is highly lethal and difficult to detect early. In a new study, researchers report that people who had high levels of antibodies for an infectious oral bacterium turned out to have double the risk for developing the cancer. High antibody levels for harmless oral bacteria, meanwhile, predicted a reduced pancreatic cancer risk.
PROVIDENCE, R.I. [Brown University] — A new study finds significant associations between antibodies for multiple oral bacteria and the risk of pancreatic cancer, adding support for the emerging idea that the ostensibly distant medical conditions are related.
The study of blood samples from more than 800 European adults, published in the journal Gut, found that high antibody levels for one of the more infectious periodontal bacterium strains of Porphyromonas gingivalis were associated with a two-fold risk for pancreatic cancer. Meanwhile, study subjects with high levels of antibodies for some kinds of harmless “commensal” oral bacteria were associated with a 45-percent lower risk of pancreatic cancer. (more…)
