Inhaling the aroma of dark chocolate before and during strength training can increase the number of repetitions performed and reduce feelings of hunger, without causing additional fatigue. However, this effect requires further research.
A new study has shown that patients with Parkinson's disease experience changes not only in their sense of smell but also in their reaction to unpleasant odors—they do not hold their breath like healthy individuals do. These characteristics could serve as an additional diagnostic marker for the disease.
The study revealed that the life cycle of red-necked nightjars is closely linked to the phases of the Moon: these birds are most active during the full moon, while during the new moon they enter a state of torpor to conserve energy. Lunar cycles also influence the migration and breeding patterns of these nocturnal birds.
A new study has shown that infrasound, even when it is not consciously perceived, triggers physiological stress and intensifies negative emotions, making music sound sadder and more irritating.
Recent studies have shown that red blood cells begin to absorb glucose more actively when oxygen levels are low, which reduces the risk of diabetes among people living in high-altitude regions. These discoveries could lead to new approaches in the treatment of diabetes and other metabolic disorders.
A new study has shown that the emotional tone of the human voice affects the physical state of dogs, triggering involuntary physiological responses related to their balance and stability.
