What’s does Social Media Mean for the Communication of Science and Science Journalism?

There have been a number of interesting pieces recently on the changing or unchanging (depending on perspective) face of science journalism with the advent of social media. Helen Jaques from the BMJ writes on a recent conference where many of these issues were discussed including the new roles of the science journalist. Cameron Neylon has an interesting piece on aggregating science communication in which he comments on the development of the semantic web:-

We need the authoring tools that help us build and aggregate these objects together and tools that make forming these citations easy and natural by using the existing ideas around linking and referencing but if we can build those we get the semantic web for science as a free side product – while also making it easier for humans to find the details they’re looking for‘*

A New Species or Not?

A finding of general interest for human evolution is the skeleton of a child in a cave in South Africa which has been named as a new species – Australopithecus Sediba and is estimated to have lived between 1.78 to 1.95 million years ago . Although there is suggestion that this species may be intermediate between Austrolopithecus  and Homo Sapiens, critics have argued that further work remains to be done to examine a number of standard morphological features before conclusions can be drawn.
