Author: Jose V. Torres-Perez (@Jovitope) is a Postdoctoral Researcher at the School of Biological and Chemical Sciencies, Queen Mary, University of London (UK). This is the story of primary cilium, a cellular structure discovered at least 122 years ago. It was soon regarded as rudimentary and then forgotten for most researchers. Nonetheless, recent advances proved […]
Parrots appear to altruistically help each other out Researchers filmed one African grey parrot helping another get a reward, an act of altruism they say hasn’t been demonstrated before in birds. “We found that African grey parrots voluntarily and spontaneously help familiar parrots to achieve a goal, without obvious immediate benefit to themselves,” said Desiree […]
Topological insulators are materials with special universal properties, which are protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting […]
2020 marks exactly half a century from the publication of one of the most important papers in the crossing of economics, philosophy, and political science (and, taking into account that it barely contained six skimpy pages, probably one of the most influential papers per page ever): Amartya Sen’s “The impossibility of a Paretian liberal”. It […]
Australia bushfires create their own weather Australia’s bushfires are creating their own weather in the form of pyrocumulonimbus clouds, which generate massive thunderstorms capable of starting more fires. “These fire-induced storms can spread fires through lightning, lofting of embers and generation of severe wind outflows,” Australia’s Bureau of Meteorology said in a tweet. Insider Bears’ […]
The cerebral cortex is a limited resource. Evolution has employed some impressive tricks to increase the amount of cortex available, such as folding it, therefore getting more surface in the same volume, or putting different things in the left and right hemisphere instead of duplicating them, thus enlarging its capacity to accommodate specific functions such […]
NY forest fossils date back 386M years The 386-million-year-old fossils of trees found in New York’s Catskills are likely the remains of the world’s oldest forest. Researchers found the remains of three different types of trees in what is now a quarry. New Scientist Ancient seawall finally gave way to rising waters A seawall dating […]

Nonlinear processes are attractive in microscopy and spectroscopy since they can be excited with light in the near‐infrared, which offers several advantages, from a deep tissue penetration capability or a reduced photodamage due to the lower photon energy, to a spatially more confined probed volume, which can result in an improved lateral resolution. These processes […]
An invasive species can be any kind of living organism—an amphibian (like the cane toad), plant, insect, fish, fungus, bacteria, or even an organism’s seeds or eggs—that is not native to an ecosystem and causes harm. They can harm the environment, the economy, or even human health. Species that grow and reproduce quickly, and spread […]
Despite creative efforts to tackle it, belief in conspiracy theories, alternative facts and fake news show no sign of abating. This is clearly a huge problem, as seen when it comes to climate change, vaccines and expertise in general – with anti-scientific attitudes increasingly influencing politics. So why can’t we stop such views from spreading? […]
