Flowers are the reproductive organs of angiosperms (flowering plants) and flowering is therefore the phenomenon by which the undifferentiated cells from the meristems (similar to animal stem cells) differentiate into a floral meristem that will then produce the different components […]

Quantum computers are one of the most promising technologies under development, and all their promises are completely justified. Quantum systems are extremely expensive to compute, where “expensiveness” can be measured either by the memory or the computational time required in […]

Our metastable universe
Under the simplest assumptions, the measured mass of the Higgs could mean the universe is eventually unstable and destined to fall apart.

Could flow batteries back up electric grids?
To power flow batteries, two […]

The lungs of birds move air in only one direction during both inspiration and expiration through a set of tubular gas-exchanging bronchi called parabronchi. On the other hand, in the lungs of mammals and other vertebrates, air moves tidally into […]

The genome is the text of life. Its ink is the deoxyribonucleic acid (DNA), a heteropolimer of four nucleotides (guanine, adenine, thymine, and cytosine). It encodes the instructions to make work all known living organisms (and viruses). It was isolated […]

The notion of ‘cause’ has a bipolar personality within the sciences. On the one hand, it is difficult to resist to the old Aristotelian dictum that real scientific knowledge (episteme) is knowledge of the causes; after all, one […]

You’re sitting in a room with an all-southern view. Suddenly, a bear walks by the window. What color is the bear?
Young Sherlock Holmes. Barry Levinson (1985)
The polar bear (Ursus maritimus) is one of the most unmistakable […]

News on global warming and sea-level rise flood our daily life. Even a modest decimeter increase of the current sea level will affect millions of people . Despite this gloomy scenario, we lack precise models to predict sea level changes […]

Bat-eating spiders are more common than you think
Bat-eating spiders are more common in the world than once believed. These spiders are found on all continents except Antarctica. Almost 90% of the web-building spider and tarantula species live in warmer […]

Scientific experiments using animals frequently involve the marking of animals that artificially changes their phenotype. For instance, penguins with flipper bands have been used to study climate change. However, as Saraux et al. show, this banding reduces penguins’ survival rate. […]
