Life on Mars - or simulated fossils?

(In the picture: on the left, before illumination with white light, the pupil is clearly visible as a bright circle against the background of the closed eyelid. On the right, after illumination with white light, the pupil has shrunk and the spot of light is correspondingly smaller. During the research, a method for image processing was also developed in order to reconstruct the diameter of the pupil from the two images).

A new technology will allow for the first time the early detection of life-threatening conditions in patients who are in a coma

With the help of an innovative development by university researchers, doctors will for the first time be able to measure the size of the pupil and its response to light even when the eyes are closed: "The development will enable early detection of abnormal parameters and will contribute to saving the lives of patients with severe brain injuries"

During the experiment, an innovative use was made of pressure measuring balls designed to allow the subjects to express aggression in a way that better simulates a natural situation.

A body odor molecule common in babies reduces aggression in men and increases it in women

These findings are among the first to directly link human behavior, brain mechanism and smell molecule

Introducing bacteria into a "chaotic state" as a way to cure diseases

A new study published in the prestigious journal Nature found that bacteria in a chaotic state are less sensitive to standard drug treatment. The researchers developed a statistical model that predicts the results of the antibiotic treatment, and accordingly offer a new therapeutic strategy: the deliberate introduction of the bacteria into a chaotic state - and the healing of the cells using drugs specially adapted to this state
