Moving… Thinking of moving… Standing still!
Brain-computer interfaces (BCI) work on the principle that measurable changes in electrical brain activity occur just by thinking about performing a task. Signals can be read, evaluated, and then converted into control signals via a machine learning system, which can then be used to operate a computer or a prosthesis. In a recently published study,…

Artificial leaves… True gas… Artificial beings… True existence…
A widely-used gas that is currently produced from fossil fuels can instead be made by an ‘artificial leaf’ that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to gasoline. (1) What is natural? What is artificial? In a cosmos without definitions, something extraordinary…

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…
