In late summer last year my doctor prescribed a monthlong course of antibiotics for an infection. Medicines like antibiotics are great at wiping out bacterial infections. The problems is that these drugs don’t differentiate between eliminating the “good” bacteria that may benefit our health and the “bad” bacteria causing infection. I was absolutely miserable and […]

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 […]

Forming large groups (flocks, banks, swarms, herds, schools, …) is characteristic of many species. The generally accepted idea is that it is an adaptive process, in which the individual improves its chances of survival by being part of a numerous group. A shark does not know which fish to attack in a sardine bank and […]

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 […]

Spiders build their webs using the silk they synthesize and secrete from their spinning glands, structures located in the back of the abdomen. The most primitive species have few glands and build their nets with fairly uniform silks. The most evolved spiders, on the other hand, have up to seven different spinning glands with which […]

In 1873, the microscopist Ernst Abbe stipulated a physical limit for the maximum resolution of traditional optical microscopy: 0.2 micrometers, or 200 nanometers (the shortest wavelength for visible light, the extreme limit of violet). This meant that scientists could distinguish whole cells, as well as some parts of the cell called organelles. However, they would […]

Maternal and paternal stress have been proved to be critical aspects of off-spring brain development. High levels of stress on pregnant mothers can alter both placental and embryonic gene expression patterns, misprogramming the brain of the newborn towards psychiatric disorders such as anxiety or depression. At the same level, paternal stress alters microRNAs and other […]
