Blood test for dogs could lead to similar human test; severe infections kill more than half of patients
COLUMBIA, Mo. – In pets and people, the time it takes to diagnose an infection may mean life or death. Now, a University of Missouri veterinarian is identifying ways to diagnose pet infections in approximately a third of the current diagnosis time. The resulting test could be used eventually for humans. (more…)
More Asian Pacific Americans hold public office in the United States than at any other time in U.S. history, a sign of the community’s growing engagement with the political process, according to a newly released political almanac published by UCLA’s Asian American Studies Center.
The 14th edition of the National Asian Pacific American Political Almanac, first published in 1976, contains information on all 3,000 current elected and appointed officials. It also analyzes political trends and makes electoral projections of the nation’s 17 million Asian Pacific Americans. (more…)
New Study Uses Reprogrammed Human Cells and Bioengineered Microthreads
A team of scientists from Worcester Polytechnic Institute (WPI) and CellThera, a private company located in WPI’s Life Sciences and Bioengineering Center, have regenerated functional muscle tissue in mice, opening the door for a new clinical therapy to treat people who suffer major muscle trauma.

SAN FRANCISCO – An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons – and large portions of the island’s bedrock rose an additional quarter of an inch in response.
That’s the finding from a network of nearly 50 GPS stations planted along the Greenland coast to measure the bedrock’s natural response to the ever-diminishing weight of ice above it.
Every year as the Greenland Ice Sheet melts, the rocky coast rises, explained Michael Bevis, Ohio Eminent Scholar in Geodynamics and professor in the School of Earth Sciences at Ohio State University. Some GPS stations around Greenland routinely detect uplift of 15 mm (0.59 inches) or more, year after year. But a temperature spike in 2010 lifted the bedrock a detectably higher amount over a short five-month period – as high as 20 mm (0.79 inches) in some locations. (more…)
Astronomers at Yale University have discovered what appear to be three fast-growing supermassive black holes in a relatively young, still-forming galaxy.
The discovery raises the possibility that this type of black hole continues to form billions of years after the Big Bang, challenging current theory. Astronomers previously thought all supermassive black holes emerged soon after the birth of the universe 13.7 billion years ago. (more…)
Lived through period of species extinction
A species of ancient predator with saw-like teeth, sleek bodies and a voracious appetite for meat survived a major extinction at a time when the distant relatives of mammals ruled the earth.
A detailed description of a fossil that scientists identify as a varanopid “pelycosaur” is published in the December issue of Naturwissenschaften – The Science of Nature. Professors Sean Modesto from Cape Breton University, a U of T alumnus, and Robert Reisz from University of Toronto Mississauga provide evidence that a group of ancient, agile predators called varanopids survived for more than 35 million years and co-existed with more advanced animals.

*Rats free trapped companions, even when given choice of chocolate instead*
The first evidence of empathy-driven helping behavior in rodents has been observed in laboratory rats that repeatedly free companions from a restraint, according to a new study by University of Chicago neuroscientists.
The observation, published today in Science, places the origin of pro-social helping behavior earlier in the evolutionary tree than previously thought. Though empathetic behavior has been observed anecdotally in non-human primates and other wild species, the concept had not previously been observed in rodents in a laboratory setting. (more…)
*comScore Releases Overview of European Internet Usage for October 2011*
LONDON, UK, 9 December 2011 – comScore, Inc., a leader in measuring the digital world, today released an overview of internet 
usage in Europe, showing 376.6 million unique visitors went online in October 2011 for an average of 27.8 hours per person. This study highlights internet usage in 49 European markets aggregated into the European region and provides individual reporting on 18 markets. The study also analysed the online behaviour of mothers, defined as females age 25 and older with children in the household, showing their heavy propensity to visit retail sites. (more…)
