Genetic screening no better than traditional risk factors for predicting type 2 diabetes
Screening for a panel of gene variants associated with the risk for type 2 diabetes can identify adults at risk for the disorder but is not significantly better than assessment based on traditional risk factors such as weight, blood pressure and blood sugar levels. A multi-institutional research team, led by a Massachusetts General Hospital (MGH) physician, reports their analysis of data from the Framingham Heart Study in the November 20 New England Journal of Medicine.

Landmark study defines benefits of early HIV testing and treatment for infected infants
Testing very young babies for HIV and giving antiretroviral therapy (ART) immediately to those found infected with the virus dramatically prevents illness and death, according to a report in the New England Journal of Medicine. The study found that giving ART to HIV-infected infants beginning at an average age of 7 weeks made them four times less likely to die in the next 48 weeks, compared with postponing ART until signs of illness or a weakened immune system appeared--the standard of care when the study began.

'Enlightened' Atoms Stage Nano-Riot Against Uniformity
(PhysOrg.com) -- When atoms in a crystal are struck by laser light, their electrons, excited by the light, typically begin moving back and forth together in a regular pattern, resembling nanoscale soldiers marching in a lockstep formation. But according to a new theory developed by Johns Hopkins researchers, under the right conditions these atoms will rebel against uniformity. Their electrons will begin moving apart and then joining together again repeatedly like lively swing partners on a dance floor. Tue, 18 Nov 2008 23:37:59 +0100

Clinical neuropsychologists frequently evaluate individuals within a forensic context, and therefore must address questions regarding the possible presence of reduced effort, response bias and/or malingering. This volume offers a wide range of instructive real-world case examples involving the complex differential diagnosis where symptom exaggeration and/or malingering cloud the picture.
Written by expert forensic neuropsychologists, the scenarios described provide informed, empirically-based and scientifically-derived opinions on the topic. Issues related to malingering, such as response bias and insufficient effort, are discussed thoroughly with regard to a large number of clinical conditions and assessment instruments. Test data and non-test information are considered and integrated by the numerous experts.
Expert guidance for clinicians who must address the issue of malingering is provided in a straightforward and well-organized format. To date, there has not been a comparable collection of rich case material relevant to forensic practice in clinical neuropsychology.

Human language, cognition, and culture are unique; they are unparalleled in the animal kingdom. The claim that we can learn what makes us human by studying other animal species provokes vigorous reactions and many deny that comparative research can shed any light on the origins and character of human distinctive capacities. However, Learning from Animals? presents empirical research and an analysis of comparative approaches for an understanding of human uniqueness, arguing that we cannot know what capacities are uniquely human until we learn what other species can do.
This interdisciplinary volume explores the prospects and problems of comparative approaches for understanding modern humans abilities by presenting: (1) the latest findings and theoretical approaches in primatology, comparative psychology, linguistics, and philosophy; (2) methodological reflections on the prospects and challenges of understanding human capacities through comparative research strategies; and (3) discussions of conceptual and ethical issues.
This is the first book to address the issues raised by comparative research from such a diverse perspective. It will therefore be of great interest to students, researchers, and professionals in comparative psychology, linguistics, primatology, biology, and philosophy.

The behavioral and brain sciences are faced with important new challenges at the beginning of the new millennium. The enormous progress in cognitive neuroscience, and the importance of genetic factors and gene-environment interactions in shaping behavioral functions in early childhood, have both underscored the primacy of early experience and development on brain development and function.
The contributors to this volume discuss different paradigms and approaches in infant language and cognition, pushing the frontiers of research by innovatively combining methods, introducing new measures, and demonstrating the use of technologies and measurement approaches that can inform the study of word learning and categorization, gaze, attention, gesture, and physiological functions. The volume offers a blend of theories and empirical evidence to support, refute, or modify them. Most chapters examine the link between theory and methodology, and their appearance together in a single volume serves to inform and engage multiple disciplines, to engage everyone to think across disciplines and paradigms, to embrace the integration of creativity and science as the field continues to study in greater depth and with innovative measures and approaches, the infant pathways to language
This volume is derived from presentations and discussions from a workshop, sponsored jointly by the Merrill Advanced Studies Center, University of Kansas, and the National Institute of Child Health and Human Development, Bethesda, Maryland.

This book tackles a subject that has captured the imagination of many researchers in the field: attitudes. Although the field has always recognized that peoples attitudes could be assessed in different ways, from direct self-reports to disguised observations of behavior, the past decade has shown several new approaches to attitude measurement.
Despite the fact that there is no monolithic point of view with respect to implicit attitudes or measures, this book proves informative in capturing the exciting developments that have taken place over the past decade in the study of attitudes, and point the way for future exploration. Although researchers in the field have long used physiological measures, more sophisticated approaches have now been developed that rely on brain imaging techniques to examine evaluative processes. This book addresses all of these new techniques, as well as the new wave of implicit measures and the contribution they have made to understanding attitudes and attitude change.
This volume will be an essential resource for students and researchers in social psychology with an interest in the core topic of attitudes.
