A middle-aged white man raises his sword to the skies and roars to the gods. The results of his genetic ancestry test have just arrived in his suburban mailbox. His eyes fill with tears as he learns that he is […]
There was no shortage of T. rexes in the Cretaceous Scientists estimate there may have been about 2.5 billion Tyrannosaurus rexes that lived into maturity during the Cretaceous, dominating the landscape for more than 2 million years. The mathematical model […]
The standard explanation of superconductivity goes more or less like this. Electrical resistance is due to collisions of the electrons (whether treated as particles or waves) with impurities, imperfections, and especially the lattice vibrations of the metal crystal. The lattice […]
Our species, Homo sapiens, rose in Africa some 300,000 years ago. The objects that early humans made and used, known as the Middle Stone Age material culture, are found throughout much of Africa and include a vast range of innovations […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates […]
You are surely familiar with the concept that light behaves like electromagnetic radiation, and that it responds to the equation In this way, the higher the wavelength of the light, the lower its frequency, and vice versa. This means that […]
Let me make a short interruption in our series about the prehistory of philosophy of science, to discuss a completely different point. I am writing this now, just because in the last days I think I have been able to […]
During the time Aristotle spent far from Athens after the death of Plato, he lived for a few years on the island of Lesbos and in some Asia Minor cities that surrounded it, an area where a kind of ‘franchise’ […]
What differentiates us from our closest relatives and how are these differences caused? Scientists are trying to answer this question by comparing the genomic information of us and our closest relatives. Yet, we are far from having a genomic explanation […]
“So the goblins came. They pushed their way in and pulled baby out, leaving another all made of ice” Maurice Sendak, Outside over there. Fairy tales are stories, often with an evolution of centuries, that form a mutable and difficult […]
If you ask people to list the most intelligent animals, they’ll name a few usual suspects. Chimpanzees, dolphins and elephants are often mentioned, as are crows, dogs and occasionally pigs. Horses don’t usually get a look in. So it might […]
When Cern’s gargantuan accelerator, the Large Hadron Collider (LHC), fired up ten years ago, hopes abounded that new particles would soon be discovered that could help us unravel physics’ deepest mysteries. Dark matter, microscopic black holes and hidden dimensions were […]
Imagine running on a cement footpath, and then suddenly through dry sand. Just to keep upright, you would have to slow down and change the way you run. In the same way, a walking robot would have to change its […]
Earth hasn’t always been a blue and green oasis of life in an otherwise inhospitable solar system. During our planet’s first 50 million years, around 4.5 billion years ago, its surface was a hellscape of magma oceans, bubbling and belching […]

A number of technologies and tools got a chance to prove themselves for the first time in the context of COVID-19. Three researchers working in gene-based vaccines, wearable diagnostics and drug discovery explain how their work rose to the challenge […]
