New dark matter detector begins search for invisible particles

Scientists heard their first pops last week in an experiment that searches for signs of dark matter in the form of tiny bubbles.

They will need to analyze them further in order to discern whether dark matter caused any of the COUPP-60 experiment’s first bubbles at the SNOLAB underground science laboratory in Ontario, Canada. Dark matter accounts for nearly 90 percent of all matter in the universe, yet it is invisible to telescopes.

“Our goal is to make the most sensitive detector to see signals of particles that we don’t understand,” said Hugh Lippincott, a postdoctoral scientist with Fermi National Accelerator Laboratory. Lippincott has spent much of the past several months leading the installation of the one-of-a-kind detector at SNOLAB, 1.5 miles underground. (more…)

Despite free health care, household income affects chronic disease control in kids

Researchers at the University of Montreal have found that the glycated hemoglobin levels of children with type 1 diabetes followed at its affiliated Sainte-Justine Mother and Child University Hospital (CHU Sainte-Justine) is correlated linearly and negatively with household income. Glycated hemoglobin is the binding of sugar to blood molecules – over time, high blood sugar levels lead to high levels of glycated hemoglobin, which means that it can be used to assess whether a patient properly controls his or her blood glucose level. “Our study highlights a marked disparity between the rich and the poor in an important health outcome for children with type 1 diabetes, despite free access to health care”, explained Dr. Johnny Deladoëy, who led the study.

ARMONK, N.Y. – 09 Jan 2012: IBM today announced it has completed the acquisition of Platform Computing, a privately held company headquartered in Toronto, Ontario, Canada. Financial terms were not disclosed.

On October 11, 2011, IBM announced that it had entered into a definitive agreement to acquire Platform Computing, a global leader in cluster, grid and cloud management software for distributed computing environments. (more…)

U-M Divers Retrieve Prehistoric Wood from Lake Huron

ANN ARBOR, Mich.— Under the cold clear waters of Lake Huron, University of Michigan researchers have found a five-and-a-half foot-long, pole-shaped piece of wood that is 8,900 years old. The wood, which is tapered and beveled on one side in a way that looks deliberate, may provide important clues to a mysterious period in North American prehistory.

“This was the stage when humans gradually shifted from hunting large mammals like mastodon and caribou to fishing, gathering and agriculture,” said anthropologist John O’Shea. “But because most of the places in this area that prehistoric people lived are now under water, we don’t have good evidence of this important shift itself– just clues from before and after the change.

Does Social Anxiety Disorder Respond to Psychotherapy? Brain Study Says Yes

When psychotherapy is helping someone get better, what does that change look like in the brain? This was the question a team of Canadian psychological scientists set out to investigate in patients suffering from social anxiety disorder. Their findings are published in Psychological Science, a journal of the Association of Psychological Science.

Social anxiety is a common disorder, marked by overwhelming fears of interacting with others and expectations of being harshly judged. Medication and psychotherapy both help people with the disorder. But research on the neurological effects of psychotherapy has lagged far behind that on medication-induced changes in the brain. (more…)

Unexpected Exoskeleton Remnants Found in Paleozoic Fossils

Washington, D.C.— Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex—structural materials containing protein and polysaccharide—are present in abundance in fossils of arthropods from the Paleozoic era. Previously the oldest molecular signature of chitin-protein complex was discovered in 25 million year old Cenozoic fossils and remnants of structural protein have also been discovered in 80 million-year-old Mesozoic fossils. Carnegie’s George Cody and an international team of scientists discovered relicts of protein-chitin complex in fossils of arthropods from the Paleozoic era. Their findings, published online by Geology, could have major implications for our understanding of the organic fossil record. (more…)
