Are New Extreme Global Warming Projections Correct? – EcoWatch

By Jeff Berardelli For the past year, some of the most up-to-date computer models from the world’s top climate modeling groups have been “running hot” – projecting that global warming may be even more extreme than earlier thought. Data from…

Why are the offspring of older mothers less fit to live long and prosper?

(Marine Biological Laboratory) In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the offspring in all environments, primarily through reduced fertility during their peak reproductive period. They also suggest an evolutionary mechanism for why this may occur.

Call for immunology to return to the wild

(Menzies Institute for Medical Research ) In an article published today in Science, a multidisciplinary research team from more than 10 universities and research institutes outlines how integrating a more diverse set of species and environments could enhance the biomedical research cycle.

Aboriginal artifacts reveal first ancient underwater cultural sites in Australia

(Flinders University) The first underwater Aboriginal archaeological sites have been discovered off northwest Australia dating back thousands of years ago when the current seabed was dry land.Aboriginal artefacts discovered off the Plibara coast in Western Australia were discovered through a series of archaeological and geophysical surveys in the Dampier Archipelago, as part of the Deep History of Sea Country Project, funded through the Australian Research Council’s Discovery Project Scheme.
