Packaging is essential to preserve the food quality and safety and to extend the shelf life of the stored product reducing the food waste. In this sector, plastics are the material of choice because they are cheap, lightweight and easy to process. The main requirement for packaging materials is to maintain the food in good […]
Scientific disinformation about climate change is having a great impact especially in countries like the United States (USA). Misinformation about this topic and about scientific issues in general, not only confuses the population and discredits scientific findings but also paralyzes evidence-based policies. Farrell et al (2019) provide a series of examples and strategies that can […]
Einstein’s theory helps map pulsar’s beams Researchers used Einstein’s theory of general relativity to map the structure of the pulsar PSR J1906+0746 and, by doing so, they also confirmed the theory. Astronomers observed the pulses coming from PSR J1906+0746 over the course of 14 years. ScienceAlert Whale’s song can reveal where it has been The […]
Man does not live by hardware alone. Indeed, great material and conceptual improvements in the machinery of optical microscopes have occurred in recent decades. The examples are numerous (some example here; https://mappingignorance.org/2013/12/23/bessel-beam-plane-illumination-microscopy-another-smart-solution-for-an-old-challenge/). However, what is being achieved only with software and computing power seems a matter of magic. It is not only that programs and […]
The view of the horizon has always been of great inspiration for humans: that line, separating our Earth from the sky, appears so real. Looking at the Sea and its intersection with the sky, one can not avoid to wonder which things are still out of there to be found. A famous poem by Giacomo […]
Coffee is one of the most widely consumed drinks in the world. Several brewing methods can be used to prepare it depending on the consumer’s taste – or the lack of it – as well as cultural and geographical habits. My father, for example, had a ritual every time he wanted a coffee. He took […]
A group of astrophysicists (to which I have the pleasure to belong to), led by scientists from the Instituto de Astrofísica de Canarias (IAC, Spain), have recently published an article in Nature Astronomy in which the early events shaping the current view of our Galaxy, the Milky Way, have been unveiled . Such discovery has […]
Frog brain study looks for parenting clues Some poison dart frogs take an active role in parenting their young rather than disregarding eggs once they are laid, and researchers found brain regions in males and females that could offer clues about such behavior. Scientists compared neural activity in three species of poison dart frogs that […]

The so-called van der Waals materials consist of two-dimensional layers bound by weak van der Waals forces. After the isolation of graphene, the field of two-dimensional van der Waals materials has experienced an explosive growth and new families of two-dimensional systems and block-layered bulk materials have been created. This growth has been fueled mainly by […]
As one of those people who REALLY love to sleep -and doesn’t get close to enough of it- I am always interested to read on the topic. What I didn’t expect was to read about sleeping fish and how that relates to its origin . But let’s get down to the details, because if the […]
