A new study from North Carolina State University and the University of Toronto finds that people pay more attention to the upper half of their field of vision – a finding which could have ramifications for everything from traffic signs to software interface design.

“Specifically, we tested people’s ability to quickly identify a target amidst visual clutter,” says Dr. Jing Feng, an assistant professor of psychology at NC State and lead author of a paper on the work. “Basically, we wanted to see where people concentrate their attention at first glance.” (more…)

Why did life forms first begin to get larger and what advantage did this increase in size provide? UCLA biologists working with an international team of scientists examined the earliest communities of large multicellular organisms in the fossil record to help answer this question. (more…)

Targeted audiences and websites can help magazines weather the onslaught of online competition

TORONTO, ON — While print media continue to suffer at the hands of their online counterparts, new research from the University of Toronto Scarborough finds that print magazines with companion websites are able to attract more advertising dollars.

“Targeting is as important as ever,” says Ambarish Chandra, Assistant Professor at UTSC’s Department of Management. In a study of magazines in Germany, Prof. Chandra and Prof. Ulrich Kaiser of the University of Zurich found that magazines offering targeted advertising both in print and on the web can charge more from advertisers.

NASA’s Kepler Provides Insights on Enigmatic Planets

More than three-quarters of the planet candidates discovered by NASA’s Kepler spacecraft have sizes ranging from that of Earth to that of Neptune, which is nearly four times as big as Earth. Such planets dominate the galactic census but are not represented in our own solar system. Astronomers don’t know how they form or if they are made of rock, water or gas.

The Kepler team today reports on four years of ground-based follow-up observations targeting Kepler’s exoplanet systems at the American Astronomical Society meeting in Washington. These observations confirm the numerous Kepler discoveries are indeed planets and yield mass measurements of these enigmatic worlds that vary between Earth and Neptune in size. (more…)

The long game: New book probes the uneasy future of China’s relationship with the United States

TORONTO, ON – The global financial crisis accelerated China’s rise in the world economy, disrupting a post-cold war status quo in which the United States was the world’s largest and most dynamic economy and undisputed super power. The world economic order is shifting. Can those who manage international commercial, cultural or political exchanges afford to ignore this shift? (more…)

Want ripples on your icicles? University of Toronto scientists suggest adding salt

TORONTO, ON – Though it’s barely the beginning of autumn, scientists at the University of Toronto are one step closer to explaining why winter’s icicles form with Michelin Man-like ripples on their elongated shapes.

Experimental physicist Stephen Morris and PhD candidate Antony Szu-Han Chen were spurred to investigate by the ripples that appear around the circumference of icicles that occur naturally. It has been theorized that the ripples are the result of surface tension effects in the thin water film that flows over the ice as it forms. Their investigation revealed that the actual culprit is salt. (more…)

Researchers shed light on MERS Coronavirus transmission

Epidemiology and gene sequencing technologies have been used by researchers in the UK, the Kingdom of Saudi Arabia, the US and Canada to show that the novel Middle East Respiratory Syndrome (MERS) coronavirus can spread between people in healthcare settings. The work is published in the New England Journal of Medicine.

The scientists, from the Saudi Arabian Ministry of Health, UCL, Wellcome Trust Sanger Institute, University of Toronto, University of Colorado and Johns Hopkins University, rapidly investigated and defined the epidemiology, transmission dynamics and genetic composition of the MERS-CoV cluster of 22 cases of healthcare-acquired MERS coronavirus infections from a recent outbreak in Al-Hasa, Eastern Province, Kingdom of Saudi Arabia.

Self-fertilizing plants contribute to their own demise

TORONTO, ON – Many plants are self-fertilizing, meaning they act as both mother and father to their own seeds. This strategy – known as selfing – guarantees reproduction but, over time, leads to reduced diversity and the accumulation of harmful mutations. A new study published in the scientific journal Nature Genetics shows that these negative consequences are apparent across a selfing plant’s genome, and can arise more rapidly than previously thought.

In the study, an international consortium led by Stephen Wright in the Department of Ecology and Evolutionary Biology at the University of Toronto and Detlef Weigel at the Max Planck Institute for Developmental Biology sequenced the genome of the plant species Capsella rubella, commonly known as Red Shepherd’s Purse. They found clear evidence that harmful mutations were accumulating over the species’ relatively short existence. (more…)
