We are thrilled to announce that David Robert Grimes and Mariana Ribeiro will join the Retraction Watch team as Sleuths in Residence starting June 1. Earlier this year we announced the Sleuth in Residence Program, an opportunity for active sleuths to have a secure and paid position while working closely with our research team on specific projects, and with our journalism team to publish their findings. Our goal is to build capacity in this space to emphasize the value of compensating and protecting the critical work of sleuths. We’re pleased to be able to bring on two Sleuths in Residence…

The immune system is regulated by a body clock and is more active during the day, scientists at Waipapa Taumata Rau, University of Auckland have discovered. A breakthrough study, led by scientists at Waipapa Taumata Rau, University of Auckland, has uncovered how daylight can boost the immune system’s ability to fight infections. The team focused on the most abundant immune cells in our bodies, called ‘neutrophils’, which are a type of white blood cell. These cells move quickly to the site of an infection and kill invading bacteria. The researchers used zebrafish, a small freshwater fish, as a model organism,…

Credit: National Institute on Aging/NIH Investigative journalist Charles Piller’s latest book, Doctored: Fraud, Arrogance, and Tragedy in the Quest to Cure Alzheimer’s, came out in February. It details the work of Matthew Schrag, a neurologist at Vanderbilt University in Nashville, Tenn., and other sleuths who uncovered evidence of problems in hundreds of research papers about the neurologic condition.  Most reviews and coverage have been positive, Piller said. But some Alzheimer’s researchers have criticized the book in reviews published in JAMA, The Lancet Neurology, and the website Alzforum, which hosts news and commentary…

Chronic stress can lead to increased blood pressure and cardiovascular disease, decreased immune function, depression, and anxiety. Unfortunately, the tools we use to monitor stress are often imprecise or expensive, relying on self-reporting questionnaires and psychiatric evaluations. Now a Tufts interdisciplinary engineer and his team have devised a simple device using specially designed floss that can easily and accurately measure cortisol, a stress hormone, in real time. “It started in a collaboration with several departments across Tufts, examining how stress and other cognitive states affect problem solving and learning,” said Sameer Sonkusale, professor of electrical and computer engineering. “We didn’t…
