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 […]

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. […]

Many animals —including mammals, birds and fishes— acquire from others knowledge and skills which may develop into behavioural traditions. Outside of humans, it is in the primates —specially chimpanzees— where socially transmitted behaviour patterns, such as tool use and social […]

NGC1365 is a beatiful galaxy. It is big and bright enough to be observed with a medium-sized amateur telescope. Sometimes mis-located at the southern constellation of Eridanus, it is indeed located in the smaller Fornax constellation and it is one […]
