Neuroimaging’s Bias Against Left-handers

Posted on Categories Discover Magazine

Left-handed people are under-represented as volunteers in human neuroimaging studies, according to a new paper from Lyam M. Bailey, Laura E. McMillan, and Aaron J. Newman of Dalhousie University. Bailey et al. analyzed a sample of 1,031 papers published in 2017, finding that just 3.2% of participants were non-right-handed, even though this group makes up about 10-13% of the general population. These findings are hardly unexpected. The exclusion of non-right-handed people from neur ...read more

A Massive Star Completely Destroyed by a Supernova is Puzzling Scientists

Posted on Categories Discover Magazine

Supernova 2016iet is an example of one of the most extreme types of stellar explosions, though it has some odd features. (Credit: Gemini Observatory/NSF/AURA/ illustration by Joy Pollard) In November of 2016, the sharp-eyed Gaia spacecraft spied a supernova that exploded some billion light-years from Earth. Astronomers followed up with more telescopes, and quickly realized that this supernova – dubbed SN2016iet – was an odd one in many ways. For one, the star that caused the s ...read more

Microplastics Are Falling Along With Snow in the Arctic

Posted on Categories Discover Magazine

Frigid terrain on the Norwegian archipelago of Svalbard, where researchers recently documented microplastic pollution in falling snow. (Credit: Sejsejlija/Shutterstock) When it snows in the Arctic, there's another kind of flake drifting down alongside the ice crystals. Tiny bits of degraded plastic, commonly called microplastics, have been found swirling among the snow in otherwise pristine Arctic environments. Microplastic pollution has previously been found everywhere from city streets ...read more

Why Do We Still Believe in ‘Lunacy’ During a Full Moon?

Posted on Categories Discover Magazine

The full moon has been associated with aberrant behavior for centuries. (Credit: Aron Visuals/Unsplash) It’s sometimes called the "Transylvania effect.” In the dark sky, the clouds shift, revealing the full moon’s eerie silver gleam, and the people on Earth below go mad. It’s a story that gets repeated by doctors, teachers and police officers. The science, though, says something different. Blaming the full moon for strange behavior is a time-honored tradition. In th ...read more
