Researchers at the University of Queensland have found that humans can understand the emotional state of chickens from the sounds of their clucking. This ability, which is not affected by previous experience with chickens, has significant implications for improving poultry welfare and can assist in the development of artificial intelligence-based surveillance systems.

Research led by the University of Queensland has found that humans can tell if chickens are excited or disappointed, simply by the sound of their clucking
New research shows great apes have an extraordinary social memory, recognizing former group members even after more than 25 years. This finding, which indicates a significant cognitive similarity between great apes and humans, emphasizes the depth and duration of social ties in our animal relatives. The study found the longest-lasting non-human social memories ever recorded. Photo: Johns Hopkins University

  • One response
With the approach of the German army to Paris, Marie Curie was forced to retrain in the absence of the ability to research radium. She came up with an idea - to equip vehicles with X-ray devices and bring them close to the front to better diagnose the wounded soldiers. Even the concept of an ambulance did not exist yet

In the tears you cry: smelling women's tears reduces aggression in men

Scientists at the Weizmann Institute of Science discovered that tears activate human olfactory receptors, even though they are odorless, affecting the brain activity associated with aggression - and leading to more peaceful and less vengeful behavior

On the right: the brain's response to speech that is listened to (above) and speech that is tried to be ignored. It can be seen that the brain's response is stronger to attentive speech and that this response involves more brain areas, with an emphasis on hearing and language areas.

The biology of listening

The human attention system can be dynamic, efficiently jumping between stimuli and taking in a lot of information, so it is not static as is commonly thought.

Why are diabetics more susceptible to respiratory infections?

35% of the corona patients who died in the epidemic were diabetics. In a new study, Weizmann Institute of Science scientists reveal that high blood sugar levels disrupt the immune system's ability to fight lung infections and present a therapeutic approach that may save lives
Brain during stress and without it. SN - the saliency network: reacts to significant events for a person, and when stressed expands in the cerebral cortex at the expense of the executive functions network ECN - the executive functions network: involved in attention, working memory, emotional regulation and social functioning and studies DMN - the default network: a system of brain areas that is mainly active in situations Rest in which the person is awake.

The development of the disease in celiac patients is probably related to sensitivity to the protein common in industrialized dairy products. The findings pave the way for early detection of the disease and its prevention

Japanese researchers from Nagoya University have revealed new aspects of the interaction between mast plants or mass seeding plants, i.e. plants that spread their seeds at once like Sasa bamboo and field mice. Their research reveals that mouse behavior (which varies between species, and varies according to environmental conditions and seasons) plays a crucial role in seed dispersal and ecosystem health in forests, and challenges existing theories about seed storage and consumption.
