(Credit: current value/Shutterstock) To be human is to be curious. Our constant interrogation of the world around us has led to pretty much every bit of knowledge we hold as a species. This is what scientists do, through carefully controlled experiments and quantitative data collection.

With many of us spending our time online, we tend to be laser-focused on preventing our personal information from falling into the hands of nefarious hackers. But let’s not forget about the security of print-based communications. Remember how the ink appears and disappears on the Marauder’s Map that appears in Harry Potter and the Prisoner of Azkaban?

But the salamander’s appearance wasn’t just seasonally appropriate—it was the first time anyone had laid eyes on the species in 42 years. Two Americans first discovered Jackson’s climbing salamander (Bolitoglossa jacksoni) while hiking in the cloud forests in 1975. Its name came from one ...read more

It’s the first time we can confirm that an eclipse was ever recorded for posterity, say researchers fro ...read more

The Voodoo Curse of Circular fMRI Analysis

Posted on Categories Discover MagazineLeave a comment on The Voodoo Curse of Circular fMRI Analysis

Remember the ‘voodoo’ fMRI controversy? Well, I just came across a new voodoo-ish paper – just in time for Halloween. The study, published in Neuropsychopharmacology, comes from Franziska Plessow and colleagues of Boston. The main claim is that a dose of oxytocin reduced the response of “reward-related food motivation brain regions” to pictures of high-calorie foods, suggesting that the hormone might be of use in the treatment of obesity. However, I have some ...read more
