A substance in breast milk that neutralizes HIV and may protect babies from acquiring HIV from their infected mothers has been identified for the first time by researchers at Duke Medicine.
States across the country have started to implement the Common Core State Standards for Mathematics (CCSSM). But, according to a National Science Foundation-funded study, a large majority of middle school math teachers point to the new high-stakes tests and teacher evaluations associated with the CCSSM as challenges for implementing the new standards. In fact, most teachers reported that the content of these new state assessments and the teacher evaluation systems aligned with the CCSSM will ultimately drive their classroom practices.
These are among other findings released as part of a new survey, conducted by researchers from the University of Rochester, Western Michigan University, Michigan State University, and Washington State University Tri-Cities in April and May 2013, that examines how teachers perceive the new standards, CCSSM-related assessments, and the teacher evaluation process linked to the new standards.
A new Department of Energy grant will fund research to advance an additive manufacturing technique for fabricating three-dimensional (3D) nanoscale structures from a variety of materials.

“Sticks and stones may break my bones, but words will never hurt me,” goes the playground rhyme that’s supposed to help children endure taunts. But a new study suggests that there’s more going on inside our brains when someone snubs us – and that the brain may have its own way of easing social pain.
A new paper published in the journal Climate Dynamics suggests that ‘unpredictable climate variability’ behaves in a more predictable way than previously assumed. The paper’s authors, Marcia Wyatt and Judith Curry, point to the so-called ‘stadium-wave’ signal that propagates like the cheer at sporting events whereby sections of sports fans seated in a stadium stand and sit as a ‘wave’ propagates through the audience.
Using the Food and Drug Administration's Adverse Event Reporting System (FAERS), a hospital electronic health records database, and an animal model, a team of researchers at the Icahn School of Medicine at Mount Sinai report that by adding a second drug to the diabetes drug rosiglitazone, adverse events dropped enormously. That suggests that drugs could be repurposed to improve drug safety, including lowering the risk of heart attacks.
Using mice, lab-grown cells and clues from a related disorder, Johns Hopkins researchers have greatly increased understanding of the causes of systemic sclerosis, showing that a critical culprit is a defect in the way certain cells communicate with their structural scaffolding. They say the new insights point the way toward potentially developing drugs for the disease, which affects approximately 100,000 people in the United States.
Researchers at The Johns Hopkins University working in a novel mouse model of Stiff Skin Syndrome have made key discoveries that may have broad implications for future scleroderma therapy.
