300,000 years earlier than believed
An international team led by the University of Toronto and Hebrew University has identified the earliest known evidence of the use of fire by human ancestors. Microscopic traces of wood ash, alongside animal bones and stone tools, were found in a layer dated to one million years ago at the Wonderwerk Cave in South Africa. (more…)
How do children come to realize that they themselves might be targets of prejudice? It may depend on their age. New research conducted at the University of Toronto shows that a six-year-old may be influenced most by direct instruction about prejudice, but once that child gets closer to 10, she begins to rely more on her own experiences.
“Young children are information hungry – they are eagerly searching for general rules to help in mapping out their social worlds,” write researchers Sonia Kang, an assistant professor in the Department of Management at U of T Mississauga and the Rotman School of Management, and Professor Michael Inzlicht of the Department of Psychology in this month’s Personality and Social Psychology Bulletin.

Normative support for equality can make the difference
Countries that more strictly uphold their cultural norms are less likely to promote women as leaders, unless those norms support equal opportunity for both sexes, shows a new paper from the University of Toronto’s Rotman School of Management.
“Cultural tightness can prevent the emergence of women leaders because tighter cultures may make a society’s people more resistant to changing the traditionally-held practice that placed men in leadership roles,” said Professor Soo Min Toh, who is cross-appointed to the Rotman School and the University of Toronto Mississauga, and co-wrote the paper with Professor Geoffrey Leonardelli at the Rotman School and U of T’s Department of Psychology.

*Pikaia is most primitive vertebrate known*
Researchers from the University of Toronto, the Royal Ontario Museum (ROM) and the University of Cambridge have confirmed that a 505 million-year-old creature, found only in the Burgess Shale fossil beds in Canada’s Yoho National Park, is the most primitive known vertebrate and therefore the ancestor of all descendant vertebrates, including humans.
The research team’s analysis proves the extinct Pikaia gracilens is the most primitive member of the chordate family, the group of animals that today includes fish, amphibians, birds, reptiles and mammals. Their study is based on the analysis of 114 specimens and is published in the British scientific journal Biological Reviews. (more…)
*Data essential for creating fair policies*
While only 20 per cent of Canada’s police forces have an explicit policy against reporting the race of victims and accused persons, criminologists from the University of Toronto and Nipissing show that the majority of police departments do not report race in practice.
The study, by Akwasi Owusu-Bempah, a PhD candidate at the University of Toronto’s Centre for Criminology, and Paul Millar, an associate professor at Nipissing University’s School of Criminology and Criminal Justice, is entitled Whitewashing Criminal Justice in Canada: Preventing Research through Data Suppression and appears in the current issue of the Canadian Journal of Law and Society.

*Lived in the ocean more than 500-million years ago*
A bizarre creature that lived in the ocean more than 500-million years ago has emerged from the famous Middle Cambrian Burgess Shale in the Canadian Rockies.
Officially named Siphusauctum gregarium, fossils reveal a tulip-shaped creature that is about the length of a dinner knife (approximately 20 centimetres) and has a unique filter feeding system. (more…)
*PhD candidate explores their interconnection*
Like any 28 year old, Arif Jetha, a fourth-year PhD candidate at the University of Toronto’s Dalla Lana School of Public Health, is worrying about his future. Once he completes his PhD, should he remain at home with his parents and pursue post-doctoral work or move on to full-time employment and begin establishing his career?
Then, he thinks about the participants in his Young Adult, Health and Employment Study (YHES) ) and realizes his own challenges pale in comparison to theirs. They are 18- to 30-year-olds who live with disabling health conditions such as lupus, juvenile arthritis and spinal cord injuries, and the transition to adulthood and employment is often exacerbated by their health status.

*U of T, U.K. study focused on Avastin*
Treating ovarian cancer with the drug bevacizumab (“Avastin”) delays the disease and may also improve survival, according to an international clinical trial co-led by Drs. Amit Oza of the University of Toronto and Princess Margaret Hospital (PMH) and Timothy Perren of St James’s Institute of Oncology, Leeds, U.K.
The findings, published on Dec. 28 in the New England Journal of Medicine, report that the drug halted the cancer’s return for two months overall. However, for women with the highest risk disease, the delay was five to six months and in this group, the findings also indicate a strong trend to improved overall survival, which is being analysed until 2013.
