(Phys.org)—An international team of researchers has found evidence that suggests a human ancestor – Australopithecus bahrelghazali – was eating grass plants almost a million years earlier than most scientists had thought. In their paper published in the Proceedings of the National Academy of Sciences, the team says carbon dating of tooth fossil samples found in Chad indicate early hominins had been dining on a diet heavy in plants that contained 4 carbon atoms (C4), which are typical of grasses or sedges. http://phys.org/news272011282.html Other Sciences Tue, 13 Nov 2012 07:00:01 EST news272011282 Goggles that trick the wearer into thinking the plain snack in their hand is a chocolate cookie, or make biscuits appear larger have been unveiled in Japan, offering hope to weak-willed dieters everywhere. http://phys.org/news258003812.html Electronics Mon, 04 Jun 2012 04:43:53 EST news258003812 Many Christians give up certain foods for Lent, however ecologists have discovered these changes in human diet have a dramatic impact on the diet of wild animals. In Ethiopia, members of the Orthodox Tewahedo Church stop eating meat and dairy products during a 55-day fast before Easter. As a result, spotted hyenas too change their eating habits – from scavenging waste from butchers and households to hunting – new research in the British Ecological Society's Journal of Animal Ecology has found. http://phys.org/news252768777.html Biology Wed, 04 Apr 2012 19:00:02 EST news252768777 The Starving Time came about after John Smith returned to England in 1609 and the uneasy truce he had brokered with the Powhatan Indians fell apart and led to the beginning of the First Anglo-Powhatan War. http://phys.org/news238054958.html Other Sciences Mon, 17 Oct 2011 07:23:43 EST news238054958 Does eating a big breakfast help weight loss or is it better to skip breakfast altogether?

The responsibility of identifying and treating eating and weight-related problems early in children and adolescents falls to health care providers and other professionals who work with the child, according to Professor Denise Wilfley and colleagues from the Department of Psychiatry at Washington University School of Medicine in the US. Furthermore, the key to successful treatment is a team effort involving providers and parents. http://phys.org/news206791570.html Medicine & Health Wed, 20 Oct 2010 11:06:21 EST news206791570 If you think you eat healthier at the Sunburst Fresh Cafe than at Big Jims Beefy BBQ, you might be wrong.
