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 […]

Thin films are defined as material layers ranging from nanometers to several micrometers of thickness that are deposited onto a matrix in order to modify its physical characteristics. Although solar cells conform a relevant field of application, it may be […]

3-body problem gets 13 more possible solutions
Scientists have come up with 13 new solutions to the “three-body problem,” a situation in which three objects orbit each other in a pattern. The discoveries, which will help astrophysicists further understand planetary […]

From a certain point of view, eukaryotic cells could be described as microscopic power plants equipped with factories and energy-generating platforms, inside of which highways and compartments are constantly built and rebuilt, and a fluent traffic provides a constant recycling […]
