Photosynthesis fix may enhance food production Researchers are trying to replicate in food crops a change they made to tobacco plants that repaired a defect in photosynthesis in which plants inadvertently took hold of oxygen molecules instead of carbon dioxide, forcing the plant to use valuable energy clearing up that mistake. Researchers have tried to […]

You can read this article because I have used photonics in order to make it possible. It may sound futuristic, but photonics is a technology we use, one way or the other, on a daily basis. Photonic devices are analogous to those used in electronics, but with the electrons replaced by photons. Thus, photonics is […]
In spite of the title of his most important book ( The Logic of Scientific Discovery -LSD-, published originally in German as The Logik der Forschung , in 1935), Karl Popper’s fundamental claim about the rules of science is that they are not a matter of logic , in the sense that they cannot be […]
Shark tooth in pteranodon fossil suggests air-sea battle A shark tooth has been found embedded in the partial skeleton of a pteranodon that lived during the Late Cretaceous period. “We’ve got good direct evidence that a good-sized shark took a chunk out of a big flying reptile over 80 million years ago,” said Michael Habib […]

Some metals, alloys and transition-element salts exhibit a form of magnetism called antiferromagnetism. This occurs below a certain temperature, named after Louis Néel, when an ordered array of atomic magnetic moments spontaneously forms in which alternate moments have opposite directions. There is therefore no net resultant magnetic moment in the absence of an applied field […]
The share of the world’s population living below the global extreme poverty line has dropped from 42% in 1981 to 11% in 2013. This dramatic change has encouraged the UN to set the goal of ending it by 2030. Can it happen? In a recent article published in the Journal of Economic Perspectives, Page and […]
Observations vs intuitions Einstein’s Theory of Relativity introduced us to the concept of Spacetime, as a unified entity. This stands in contrast with the intuition that we develop since birth, which leads to naturally separate space and time. Human intuition is a way to understand how the world works, our brain processes our daily experiences […]
Juno space probe gets close-up view of storms at Jupiter’s poles Massive storms at the poles of Jupiter have been spotted in images taken by a camera on NASA’s Juno space probe and processed by citizen scientists. BBC Elongated skulls may be linked to Neanderthal DNA Some modern-day humans with slightly more elongated skulls may […]
Two-dimensional materials, such as transition-metal dichalcogenides embedded in optical cavities, stand out as an excellent platform where strong light-matter interactions can be studied. Moreover, their band structures bring about nontrivial topological features, including the possibility of inducing some really interesting ones, like the polariton anomalous Hall effect. But, before getting into that let’s go through […]
High-moisture soft solid snack foods such as rice cakes have become increasingly popular. Most of these snacks are freshly made and sold on the spot, whilst industrially produced versions use chemical preservatives to inhibit microbial growth and improve shelf life. With the increasing demand for preservative-free foods from some consumers, physical methods are needed to […]
