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…

Mandelbrot coffee...
Nature keeps on repeating itself. And fractals are one of the best ways of showing that. In the nothing I made coffee. And the shapes developed on its surface were very much like the Mandelbrot shape one can see in almost all the chaos theory textbooks. Take a look... What does that mean? I don't…

Statistical significance. Not so… significant!
In science, the success of an experiment is often determined by a measure called “statistical significance.” A result is considered to be “significant” if the difference observed in the experiment between groups (of people, plants, etc) would be very unlikely if no difference actually exists. The common cutoff for “very unlikely” is that you’d see…

Seeing better. And better. And better. Until we see nothing at all…
A few years ago, a team of scientists at EPFL's Laboratory of Nanoscale Biology, headed by Aleksandra Radenovic in the School of Engineering, developed an algorithm that can estimate a microscope's resolution in just a few seconds based on a single image. The algorithm's result indicates how closely a microscope is operating to its full…

Virtual 'universe machine'. Galaxy evolution. Understanding unicorns.
By creating millions of virtual universes and comparing them to observations of actual galaxies, researchers have made discoveries that present a powerful new approach for studying galaxy formation. (1) A cosmos full of phenomena. Phenomena we try to understand. Because we imagine we can. A cosmos full of laws. Laws we expect to decipher because…
