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 […]

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 […]

The cicadas are part of the soundtrack of summer. Their calls, especially if a large number of animals is gathered, can form an impressive concert. They are part of the hemiptera, the order of aphids and bedbugs, but they do […]

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 […]

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 […]

Science often advances through improvements in our ability to measure and observe. Just take the example of migrating storks. […]

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 […]

“It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present.— But if (& oh what a big if) we could conceive in some warm […]

From nucleic acids to proteins and sugar chains, all life is made up of polymers, large molecules made up of sequences of small units called monomers. However, how these macromolecules first appeared on the surface of Earth is still controversial. […]
