In the previous entry, I presented some critical thesis by historian Ylva Hasselberg regarding the applicability of economic theoretic tools to the study of the social construction of scientific knowledge. To those claims, I think we can respond with the following arguments. In the first place, we have to make a clear and emphatic distinction […]
Climate change may be speeding up ocean currents Ocean currents around the world, both on the surface and deeper, are faster than they were 20 years ago, likely due to the changing climate. “While we expected some response to the increased winds over the past two decades, that the acceleration was above and beyond that […]
Achieving room temperature superconductivity is among the most pursued but elusive goals of scientists. I n December 2014 researchers claimed to have observed superconductivity as high as 200 K in hydrogen sulfide at high pressure, breaking all the records thus far. This meant that cuprates could be knocked from their position as the highest temperature […]
Author: Martha Villabona works at Centro Nacional de Innovación e Investigación Educativa (CNIIE) of the Spanish Ministry of Education and Vocational Training, where she coordinates the area of multiple literacies. In the digital world, news are multiplying and causing readers to only choose those headlines that most interest them. This does not happen randomly or […]
The relationship between siblings is, for most people, the longest they will ever enjoy. It is fundamental for many of us, but especially for children, who live together regularly with their brother or sister, and where the fraternal relationship is part of daily life, of play and leisure, of learning basic skills, of emotional development […]
Glass bead chilled to its ground state Researchers have cooled a glass bead to close to absolute zero using a single laser with astonishing results: “Other cold-atom experiments can also create superpositions and quantum states, but what they can never do is create a superposition of all of the atoms in one place and all […]

Plasmonic nanostructures confine light to dimensions far smaller than the free-space wavelength, as they mix optical fields with electronic excitations. It was not until the 1990s, with the appearance of accurate and reliable nanofabrication techniques, that plasmonics blossomed. It was found then that local fields around nanostructures could be directly measured by near-field scanning optical […]
Finding patterns in a text could be very useful. It could reveal if the text has been written by a certain person or not, for example. Going a step further, finding sentiments in a text or a speech can also be very handy. These skills usually appear in procedural and spy movies and TV series […]
As readers of this blog will surely know, the economics of scientific knowledge is a topic on which I have worked extensively, and also written here not a few entries. Now I want to tackle a common objection to that field in itself: the idea that studying science “as if it were a market” commits […]
China shares photos from far side of moon China’s lunar mission has produced a number of photos from the far side of the moon. The images were taken by the Chang’e-4 lander and the Yutu-2 rover over the course of the last year. ScienceAlert New light on Vesuvius victims People who sheltered in boathouses in […]
