AMERICAN MARKETING ASSOCIATION Researchers from University of South Florida, European University Viadrina, Louisiana State University, SKEMA Business School, and Neoma Business School published a new Journal of Marketing article that examines how caffeine affects consumer spending. The forthcoming study is titled “Caffeine’s Effects on Consumer Spending” and is authored by Dipayan Biswas, Patrick Hartmann, Martin Eisend, Courtney Szocs, Bruna Jochims, Vanessa Apaolaza,...
by Institute of Cancer Research Credit: Pixabay/CC0 Public Domain Scientists have found that non-coding “junk” DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the way of the replication and repair of our genome, potentially allowing mutations to accumulate. It has...
by Harry Perkins Institute of Medical Research Susceptibility-associated signatures are associated with antimicrobial effect. When assayed using our FAST protocol, population-level changes in multiparametric distribution can be observed as reproducible patterns of deviation from the antimicrobial unexposed population (bounded in purple). Absence of these patterns can be used to determine a lack of susceptibility (i.e., resistance)...

DOI: 10.1016/j.xcrm.2022.100679 Although COVID-19 booster vaccinations in adults elicit high levels of neutralizing antibodies against the omicron variant of SARS-CoV-2, antibody levels decrease substantially within 3 months, according to new clinical trial data. The findings, published today in Cell Reports Medicine, are from...
by Emma Rezel-Potts, The Conversation After COVID, people are at increased risk of being diagnosed with diabetes. Credit: Ahmet Misirligul/Shutterstock Since the pandemic began, we’ve learned a great deal about the disease behind it. We now regard COVID-19 as not just a respiratory disease, but a multi-system condition. Many studies have reported on complications that can occur...
by John Donne Potter, The Conversation Credit: Shutterstock/Elizaveta Galitckaia The latest omicron variant BA.5 is fast becoming dominant worldwide, including in New Zealand and Australia. As it continues to surge, reinfection will become increasingly common and this in turn means more people will develop long COVID. The two most concerning aspects of long COVID are its high...
by Anne Trafton, Massachusetts Institute of Technology Credit: Unsplash/CC0 Public Domain Over several decades, neuroscientists have created a well-defined map of the brain’s “language network,” or the regions of the brain that are specialized for processing language. Found primarily in the left hemisphere, this network includes regions within Broca’s area, as well as in other parts...
by Rutgers University Graphical abstract. Credit: Cell Stem Cell (2022). DOI: 10.1016/j.stem.2022.06.007 Rutgers scientists have found more clear-cut evidence of how the destructive proteins linked to Alzheimer’s disease attack human brain cells and destroy surrounding tissue. In one of the first studies of its kind examining human brain cells grown in a mouse brain, researchers identified a pivotal mechanism that...
by Joanna Moncrieff and Mark Horowitz, The Conversation Credit: TanyaJoy/Shutterstock For three decades, people have been deluged with information suggesting that depression is caused by a “chemical imbalance” in the brain—namely an imbalance of a brain chemical called serotonin. However, our latest research review shows that the evidence does not support it. Although first proposed in the 1960s,...
