Scientists from the Center for Innovations in Medicine in the Biodesign Institute at Arizona State University have developed a comprehensive, microchip-based technology, called immunosignature diagnosis, which can rapidly and comprehensively measure an individual’s vaccine response, promising to take much of the initial guesswork out of predicting effective vaccines. Professor Stephen Albert Johnston and Joseph Barten Legutki, used a mouse model of influenza infection to determine how...

A team of scientists at Duke Medicine and Memorial Sloan-Kettering Cancer Center has created an artificial protein coupled with a sugar molecule that mimics a key site on the outer coat of HIV where antibodies can bind to neutralize a wide variety of HIV strains. Reported during the week of Oct. 21, 2013, in the journal Proceedings of the National Academy of Sciences, the finding provides a potential new strategy in vaccine development to elicit the broadly neutralizing antibodies...

University of Notre Dame researchers Shahriar Mobashery and Mayland Chang and their collaborators in Spain have published research results this week that show how methicillin-resistant Staphylococcus aureus (MRSA) regulates the critical crosslinking of its cell wall in the face of beta-lactam antibiotics. The work, published in the Proceedings of the National Academy of Sciences, reveals the mechanistic basis for how the MRSA bacterium became such a difficult pathogen over the previous 50...

By detailing a process required for repairing DNA breakage, scientists at the Duke Cancer Institute have gained a better understanding of how cells deal with the barrage of damage that can contribute to cancer and other diseases. The insights, reported online the week of Sept. 30, 2013, in the journal Proceedings of the National Academy of Sciences, build on earlier work by the research team and identify new prospects for developing cancer therapies. The researchers have focused on a...

When faced with uncertain situations, people are less able to make decisions as they age, according to a new study by researchers at Yale School of Medicine. Published in the Sept. 30 Proceedings of the National Academy of Sciences, the study also found that older people are more risk-averse than their midlife counterparts when choosing between possible gains, but more risk-seeking when choosing between losses. Scientists have long-observed that cognitive function improves throughout...

Our brains give us the remarkable ability to make sense of situations we've never encountered before—a familiar person in an unfamiliar place, for example, or a coworker in a different job role—but the mechanism our brains use to accomplish this has been a longstanding mystery of neuroscience. Now, researchers at the University of Colorado Boulder have demonstrated that our brains could process these new situations by relying on a method similar to the "pointer" system used by...

USC microbiologists describe how 'natural killer' cells depend on enzyme to develop Natural killer (NK) cells in the human body can kill and contain viruses and cancerous tumors, and a new study from the University of Southern California (USC) describes for the first time how those cells can be manipulated by epigenetics. The discovery, detailed in the Proceedings of the National Academy of Sciences, paves the way for developing more effective cancer drugs. "Natural killer cells are...

Researchers at Karolinska Institutet in Sweden have discovered a reason why people with disorders of the thyroid gland may be more sensitive to environmental temperature. According to the study, published in the Proceedings of the National Academy of Sciences (PNAS), a previously unknown link has been found between the effects of thyroid hormone on blood vessels, and how this in turn affects body temperature. Patients with hyperthyroidism (an overactive thyroid) or hypothyroidism (an...

A team of researchers has shown that 8-month-old infants expect objects they identify as animals to have insides. The study appears in the Proceedings of the National Academy of Sciences. University of Illinois professor of psychology Renée Baillargeon, who led the new study with graduate student Peipei Setoh, said that many psychologists have theorized that babies are born with core physical and psychological frameworks that help them navigate the world. For instance, when babies see...

University of Montreal, McGill researchers develop new method to link signaling molecules to target regulators of cell division A team of University of Montreal and McGill University researchers have devised a method to identify how signaling molecules orchestrate the sequential steps in cell division. In an article published online today in the Proceedings of the National Academy of Sciences, the scientists explain how they could track the relationship between signaling molecules and...
