At www.geneticarchaeology.com/research/Not_so_fast_–_researchers_find_that… is a report on s study published in PNAS which uses evidence from the fossil record, and therefore relies on geological dating methodology, which is based on uniformitarianism. The object is to inform us  that lasting evolutionary change takes on average a million years to take place. The lead author is quoted as saying, 'whats interesting is not that we have so much biological diversity and evolutionary change but that we have so little. Its a paradox as to why evolution should be so slow'.

At www.physorg.com/print233511939.html a study by Standord researchers has been looking at sun spots – and they can be predicted now before they are visible.

At www.physorg.com/print233497323.html – scientists have discovered an underground river 13,000 feet below the surface – and it appears to be part of a drainage system for the rainforest region.

Meanwhile, BBC News August 23rd, says that impacts on earth may have scattered life bearing debris to other planets – as a result of a computer simulation of the debris that would be generated after the earth suffered a smack.

Lastly, at www.physorg.com/print233499097.html a paper in Science of August 26th refutes alarmist claims that drought has influenced a decline in global plant productivity in recent years – there is no threat to global food supplies from that direction. Using NASA satellite data they showed the earlier report (also published in Science, but in 2010) was in error.
