TORONTO, ON — New work by University of Toronto Scarborough researchers gives the best description yet of the neural circuits that underlie a severe mental illness called Borderline Personality Disorder (BPD), and could lead to better treatments and diagnosis.
The work shows that brain regions that process negative emotions (for example, anger and sadness) are overactive in people with BPD, while brain regions that would normally help damp down negative emotions are underactive. (more…)
A protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to “program” stem cells for regeneration, which has implications for neural therapies.
Troy Ghashghaei and Jon Horowitz, both faculty in NC State’s Department of Molecular Biomedical Sciences and researchers in the Center for Comparative Medicine and Translational Research, wanted to know more about the function of Sp2, a cell cycle regulator that helps control how cells divide. Previous research from Horowitz had shown that too much Sp2 in skin-producing stem cells resulted in tumors in experimental mice. Excessive amounts of Sp2 prevented the stem cells from creating normal cell “offspring,” or skin cells. Instead, the stem cells just kept producing more stem cells, which led to tumor formation.

For Devin Naar, the Sephardic Studies Initiative is not just a valuable historical archive; it has also been a personal journey revealing an untold family story from the years of the Third Reich.
Naar’s part of the story began about 10 years ago, when as an undergraduate at Washington University he grew interested in the history of Turkey and Greece, which for centuries until World War I was part of the Ottoman Empire. His family comes from Salonica, a port city in Northern Greece. (more…)
PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.
An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.

There are many celebrity products which are in high demand in the market. Mostly the teenagers have high craze towards celebrity products. Adolescents and the teenager groups have high fascination to look like the celebrities, most importantly to look like their favorite actor/actress, or a celebrity figure in television.(more…)
ANN ARBOR — Playing violent video games about terrorism strengthens negative stereotypes about Arabs, even when Arabs are not portrayed in the games.
That is one of the findings of an innovative new study in the January issue of Psychology of Violence, a peer-reviewed journal published by the American Psychological Association. (more…)
Rick Benjamin, adjunct assistant professor of environmental studies and public humanities, was recently appointed state poet of Rhode Island by Gov. Lincoln D. Chafee. A five-year position, the state poet serves as principal advocate for poetry in Rhode Island. Benjamin has dedicated much of his career to the intersection of poetry and community service, a relationship he incorporates into “Poetry and Community Service,” a course he teaches at Brown and other schools. Courtney Coelho spoke with Benjamin about his poetry, his mission of service, and how he intends to incorporate the two in his new position.
Describe your poetry. What is your style? What are your influences?
I have a wide range of influences. I tend to learn everything through the ear. My early influences were always oral and musical, starting with poetry I probably didn’t really understand by Eliot that my mom was reading me. So she would say things like, “So intimate, this Chopin, that I think his soul should be resurrected only among friends some two or three, who will not touch the bloom that is rubbed and questioned in the concert room.” There’s not a lot of that that I would have understood when she said it, but I did hear it and I really loved the sound of it. And Langston Hughes is a poet I became acquainted with really early on and again it was the sound and the rhythm and the music in the poetry that I responded to first. In terms of poets that I read now: Lucille Clifton, Adrienne Rich, Ruth Stone, Robert Hass, Kevin Young. (more…)
The inexpensive device could improve health in the developing world and reduce mining risks
COLUMBIA, Mo. — The hand-held scanners, or tricorders, of the Star Trek movies and television series are one step closer to reality now that a University of Missouri engineering team has invented a compact source of X-rays and other forms of radiation. The radiation source, which is the size of a stick of gum, could be used to create inexpensive and portable X-ray scanners for use by doctors, as well as to fight terrorism and aid exploration on this planet and others.
“Currently, X-ray machines are huge and require tremendous amounts of electricity,” said Scott Kovaleski, associate professor of electrical and computer engineering at MU. “In approximately three years, we could have a prototype hand-held X-ray scanner using our invention. The cell-phone-sized device could improve medical services in remote and impoverished regions and reduce health care expenses everywhere.” (more…)
