Q&A: Prof. John Cacioppo examines the profound power of loneliness

By Guest PostMay 4, 2016Health, Sciencejohn cacioppo, loneliness, power

Loneliness is as close to universal as experiences come. Almost everyone has felt isolated, even rejected.

But the power of loneliness—its potential for causing depression and other serious health problems as well as its surprising role in keeping humans safe from harm—may be more profound than researchers had previously presumed, says neuroscience researcher John Cacioppo, the Tiffany and Margaret Blake Distinguished Service Professor in Psychology.

Zika, the latest mosquito-borne virus to emerge in the Americas, is rapidly becoming a public health crisis. In Brazil, it is suspected in a sharp increase in microcephaly (a birth defect that results in newborns with smaller than normal head size), leading to anxiety amongst expecting mothers and a travel advisory from the Centers for Disease Control and Prevention. Traditionally, the virus has been fairly benign, causing a rash and a fever that is usually non-life threatening. Professor Albert Ko, chair of the Department of Epidemiology of Microbial Diseases at the Yale School of Public Health, has been working with colleagues in Brazil for months to understand if the virus has changed and what is causing the birth defects in newborns.

Wechselspiel von zwei Immunstoffen zur Abwehr bakterieller Infektionen identifiziert

Unser Immunsystem muss ständig Bakterien und Viren abwehren und dabei eine kritische Gratwanderung zwischen Über- und Unterreaktion schaffen, ähnlich wie Daedalus und Ikarus in der griechischen Mythologie, die weder zu hoch noch zu tief fliegen dürfen, um ihrem Gefängnis zu entfliehen. ImmunbiologInnen um Pavel Kovarik erforschen, was beim Balanceakt des Immunsystems auf molekularer Ebene passiert. Die WissenschafterInnen der Max F. Perutz Laboratories der Universität Wien und der Medizinischen Universität Wien zeigen, dass bei der Abwehr von Gruppe A-Streptokokken – Bakterien, die Mandelentzündung, aber auch schwere und zum Teil tödliche Infektionen auslösen können – ein perfekt abgestimmtes Wechselspiel von zwei Immunstoffen eine Schlüsselrolle spielt: Die Moleküle IL-1β und Interferon vom Typ I steuern die Stärke der Immunreaktion. Die Ergebnisse bieten neue Ansätze zur Behandlung schwerer Streptokokkeninfektionen.

A team of researchers from have discovered that lycopene – the red pigment in tomatoes – is extremely successful at guarding against the harmful effects of radiation.

Dr Ruth Edge from The University of Manchester, together with her colleagues Professor George Truscott from Keele University and Professors Fritz Boehm & Christian Witt from Berlin, undertook a study of lycopene (one of the carotenoids – plant pigments found in many fruits and vegetables) and its effectiveness at protecting against radiation at the University of Manchester’s Dalton Cumbrian Facility, part of the Dalton Nuclear Institute.
