From 'corpora amylacea' to wasteosomes: new perspectives on the removal of damaging substances in tissue
From ’corpora amylacea’ to wasteosomes: new perspectives on the removal of damaging substances in tissue
Corpora amylacea (CA) are complex aggregates described in different organs and tissues associated with ageing and degenerative processes. Described for the first time in 1779 by Giovanni Battista Morgagni in the prostate and in 1837 by Jan Evangelista Purkinje in the brain, these were named corpora amylacea (in Latin, starch bodies) by Rudolf Vichow in 1854 for their similiarities with this polysaccharide.

Savannah chimpanzees, a model for the understanding of human evolution
Savannah chimpanzees, a model for the understanding of human evolution
To prosper, most great apes need lush forests in Africa (bonobos, chimpanzees, and gorillas) or Southeast Asia (orangutans), except for some groups of chimpanzees that live in savannahs, habitats characterised by high temperatures and very low seasonal rainfall. Adriana Hernández, Serra Hunter professor at the Faculty of Psychology of the University of Barcelona, co-led the study conducted by an international team of primatologists who reviewed the existing research on the behaviour and ecology of savannah chimpanzees to understand how these apes adapt to extreme conditions.

The influence collective risks have on the acceptance of social norms is being analysed
Faced with large collective risk, such as climate change or the COVID crisis, people may accept stronger or more restrictive social norms and may be more inclined to cooperate with them. However, when the perception of risk decreases, so does adherence to these norms. This is one of the conclusions of an experimental study conducted by the Universidad Carlos III de Madrid (UC3M), the Collegio Carlo Alberto in Turin, the Italian National Research Council, the Institute for Futures Studies in Stockholm, and Mälardalen University (Sweden).

Researchers identify universal laws in the turbulent behaviour of active fluids
Researchers identify universal laws in the turbulent behaviour of active fluids
Certain groupings of bacteria or cellular tissues form systems that are called active fluids. These can flow spontaneously without having to be forced from the outside, since their components are able to generate forces and move autonomously. When the activity is high enough, the spontaneous flows become chaotic, like those observed in the turbulence of ordinary fluids.

Extreme volcanism did not cause the massive extinction of species in the late Cretaceous
Extreme volcanism did not cause the massive extinction of species in the late Cretaceous
A study published in the journal Geology rules out that extreme volcanic episodes or peaks in the eccentricity of the Earth's orbit around the sun had any influence on the massive extinction of species in the late Cretaceous. The results confirm the hypothesis that it was a giant meteorite impact what caused the great biological crisis that ended up with the dinosaur lineages and other marine and terrestrial organisms 66 million years ago.

The analysis of one of the oldest paintings in the world confirms its human origins
The analysis of one of the oldest paintings in the world confirms its human origins
One of the main challenges in archaeology is to discover the time when the symbols appeared and the implications of their use in human behaviour. The oldest paintings found to date are those from the three Spanish caves in Caceres, Cantabria and Malaga, which would be about 65,000 years old. Their dating brought an intense debate in the scientific community, because it suggests that the paintings would have been made by Neandertals.
