A U physicist will help determine if neutrinos can outrace light

Back in 2007, a physics experiment clocked elusive subatomic particles called neutrinos going faster than light.

That wasn’t supposed to happen. If the speed of light in a vacuum—denoted “c” by physicists—isn’t the universal speed limit, it would mean that Einstein put the wrong number in his famous E=mc2 equation.

University of Minnesota physicist Marvin Marshak was part of the experiment, called MINOS. It clocked beams of neutrinos shot from Fermilab, a national physics lab near Chicago, to a detector 457 miles away in the Soudan Underground Laboratory in northern Minnesota. (more…)

Minorities Pay More for Water and Sewer

EAST LANSING, Mich. — Racial minorities pay systemically more for basic water and sewer services than white people, according to a study by Michigan State University researchers.

This “structural inequality” is not necessarily a product of racism, argues sociologist Stephen Gasteyer, but rather the result of whites fleeing urban areas and leaving minority residents to bear the costs of maintaining aging water and sewer infrastructure. (more…)

Examining The Changing Face of Christianity

U of T leading centre for study of global Christianity

A century ago, 80 per cent of the world’s Christians lived in Europe and North America; today, nearly 70 per cent live in Africa, Asia, and Latin America, making Christianity a predominantly non-Western religion.

A critical mass of scholars who are looking into the implications of this shift has made the University of Toronto a leading centre for the study of global Christianity.

Christianity today has more than 2.2 billion adherents worldwide. The majority are overwhelmingly poor, displaced from rural villages into overcrowded cities in search of work, and adhere strictly to the word of Scripture, which can command their loyalty far more than state or society. (more…)

What Our Searches Tell Us About 2011: Bing Releases Most-Searched Terms of the Year

*From royal weddings and rising pop superstars to concerns for human tragedy and the global economy, Bing’s most-searched terms of the year capture America’s mood in 2011.*

REDMOND, Wash. – Nov. 28, 2011 – What do pop superstar Justin Bieber, new duchess Kate Middleton, and consumer electronics king Xbox have in common? No, they’re not all part of a wildly anticipated Hollywood sci-fi flick (at least not yet); they were some of the most popular search terms typed this past year on Bing. (more…)

New Study Finds That Even the Cleanest Wastewater Contains ‘Super Bacteria’

*University of Minnesota research suggests that wastewater treated with standard technologies contains far greater quantities*

MINNEAPOLIS / ST. PAUL — A new University of Minnesota study reveals that the release of treated municipal wastewater – even wastewater treated by the highest-quality treatment technology – can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as “superbacteria,” in surface waters.

The study also suggests that wastewater treated using standard technologies probably contains far greater quantities of antibiotic-resistant genes, but this likely goes unnoticed because background levels of bacteria are normally much higher than in the water studied in this research. (more…)

Earth’s Core Deprived of Oxygen

Washington, D.C. — The composition of the Earth’s core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well. Oxygen is the most abundant element in the planet, so it is not unreasonable to expect oxygen might be one of the dominant “light elements” in the core. However, new research from a team including Carnegie’s Yingwei Fei shows that oxygen does not have a major presence in the outer core. This has major implications for our understanding of the period when the Earth formed through the accretion of dust and clumps of matter. Their work is published Nov. 24 in Nature. (more…)
