Cosmic-scale magnetic fields. Scientific models’ dirty little secrets…
While researchers have believed for some time that magnetic fields of femto-Gauss strength extend to the largest scales in the universe — to scales larger than the largest clusters of galaxies — it is an unresolved mystery how such magnetic fields can have been created in the early universe. One logical possibility is that the…

Hunger…
Researchers discovers how hunger might make food tastier: Using optogenetic and chemogenetic techniques, researchers have identified brain circuits underlying hunger-induced changes in the preferences for sweet and aversive tastes in mice. These circuits involved Agouti-related peptide-expressing neurons, which projected to glutamate neurons in the lateral hypothalamus. From there, glutamate neurons projecting to the lateral septum…

What colour?
What colour were fossil animals? Scientists have evaluated fossil color reconstruction methods and proposed a new study framework that improves and expands current practice. (1) What a weird era. Our knowledge gets accumulated in amazing rates. And yet, we are still here. Only knowing about us. Yes, we know about the dinosaurs. But we will…

Reading. Seeing. Seeing better!
Reading is a recent invention in the history of human culture — too recent for dedicated brain networks to have evolved specifically for it. How, then, do we accomplish this remarkable feat? As we learn to read, a brain region known as the ‘visual word form area’ (VWFA) becomes sensitive to script (letters or characters).…

Hard to exist?
Astronomers have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a neutron star. (1) Should it be there? According to what we knew, perhaps no. But then again, we…
