Flexible tool use is closely associated to higher mental processes such as the ability to plan actions. Now a group of cognitive biologists and comparative psychologists found out that the apes carefully weighed their options. To do so the apes considered the details such as differences in quality between the two food rewards and the functionality of the available tools in order to obtain a high quality food reward.

Many proteins with important biological functions are embedded in a biomembrane in the cells of humans and other living organisms. But how do they get in there in the first place? Researchers have now investigated the matter.

A research group has used a non-destructive methodology to determine the role of specific algae, lichens, mosses, cyanobacteria, etc. that may be causing exfoliation and delamination, which are degrading the Sacred Rock of Machu Picchu, one of the most important symbols in the Peruvian archaeological city.

Experts have shown for the first time that the way in which the activity of two brains is connected depends on whether the dialogue takes place in the native language or in a foreign language.

An international research team has created a better understanding of Alzheimer's. They have shown that the cleaning system of the brain cells, the so-called mitophagy, is very weakened in animals and humans with Alzheimer's. And when they improve the cleaning system in the animals, the Alzheimer's symptoms almost disappear.

Learning what is dangerous by watching a video or being told (known as social learning) has just as strong an effect on our decision-making as first-hand experience of danger, researchers report. The results of the study can help to explain why we make irrational decisions.

New therapeutic molecules show promise in reversing the memory loss linked to depression and aging. These molecules not only rapidly improve symptoms, but remarkably, also appear to renew the underlying brain impairments causing memory loss in preclinical models.
