New Technologies Challenge Old Ideas About Early Hominid Diets

New assessments by researchers using the latest high-tech tools to study the diets of early hominids are challenging long-held assumptions about what our ancestors ate, says a study by the University of Colorado Boulder and the University of Arkansas.

By analyzing microscopic pits and scratches on hominid teeth, as well as stable isotopes of carbon found in teeth, researchers are getting a very different picture of the diet habitats of early hominids than that painted by the physical structure of the skull, jawbones and teeth. While some early hominids sported powerful jaws and large molars — including Paranthropus boisei, dubbed “Nutcracker Man” — they may have cracked nuts rarely if at all, said CU-Boulder anthropology Professor Matt Sponheimer, study co-author.

*Former prime minister’s speech honours Alan Gotlieb, former ambassador to U.S.*

Former prime minister Brian Mulroney, the man entrepreneur Peter Munk described as “one of our greatest statesmen,” attributed much of his success – and Canada’s under his leadership – to the personal relationships he and his ambassador cultivated with leaders south of the border.

Mulroney spoke at a University of Toronto conference, Diplomacy in the Digital Age, Oct. 13, an event held in honour of Alan Gotlieb, the former ambassador to the United States who served three prime ministers. (more…)

Two Seemingly Unrelated Phenomena Share Surprising Link

A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena. (more…)

*One youngster only six times heftier than Jupiter*

TORONTO, ON – A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters. What’s more, one cluster contains a surprising surplus of them, harbouring half as many of these astronomical oddballs as normal stars.

“Our findings suggest once again that objects not much bigger than Jupiter could form the same way as stars do. In other words, nature appears to have more than one trick up its sleeve for producing planetary mass objects,” says Professor Ray Jayawardhana, Canada Research Chair in Observational Astrophysics at the University of Toronto and leader of the international team that made the discovery.

AUSTIN, Texas — An international team of scientists that includes two University of Texas at Austin researchers has found that Ecuador’s Yasuní National Park, which sits on top of massive reserves of oil, is in the single most biodiverse region in the Western Hemisphere.

The announcement is part of a final push for the Yasuní-ITT Initiative at the United Nations General Assembly. The initiative proposes that Ecuador receive compensation for half of the revenues the nation would lose by protecting the estimated 846 million barrels of oil that lie beneath the forest. (more…)

Armonk, NY and Copenhagen, Denmark & COPENHAGEN, Denmark – 13 Oct 2011: IBM today announced it has joined a collaborative consortium to help develop an energy grid that uses at least 50 percent of renewable energy sources, such as wind power, solar energy and biogas. Led by a European Union-funded consortium, the EcoGrid EU project will demonstrate a smart energy grid that will allow smart devices to use renewable electricity based on near real-time pricing and availability.
