The tsetse fly, despite being known as the “dream fly,” does not promote restorative dreams (unless you consider death as the Eternal Sleep). Its bite transmits a deadly parasite, the trypanosome, which attacks the nervous system of its victims. The disease it transmits is known as “sleeping sickness”, but in reality trypanosomiasis (as it is really called) not only disturbs sleep cycles, but also causes sensory, motor, psychic and finally neurological disorders leading to death.

Researchers from Australia, the United States and Canada have studied videos of octopuses in the wild, finding that females they were generally more likely than males to throw things. In the videos, they use the arms and the water jets of the siphon in a coordinated way, sometimes hitting other octopuses.
A new artificial intelligence technology for cardiac imaging can potentially improve patient care, allowing doctors to examine their hearts for scar tissue while eliminating the need for the contrast injections required for traditional cardiovascular magnetic resonance imaging (CMR). The new approach works by using artificial intelligence to enhance “T1 maps” of heart tissue created by magnetic resonance imaging (MRI). These maps are combined with enhanced MRI “cinemas”, which are like films of tissue in motion, in this case, the beating heart.
A slower gait is a natural result of the aging process, but mobility problems can occur if gait speed decreases sharply. A study conducted by researchers from the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, in association with colleagues from the University College London (UCL) in the United Kingdom, points to a significant loss of speed at the time to walk in older people who have weak muscles and abdominal fat.
According to a new study presented today at the European Stroke Organization (ESO) Conference, job stress, sleep disorders and fatigue, considered non-traditional risk factors for heart attack and stroke, are increasing more sharply among women than men.
Previous neuroscience studies have shown that sleep plays an important role in the consolidation of memory. This new study goes a little further. Researchers at the University of Geneva in Switzerland recently carried out a study aimed at investigating the ways in which the brain selects memories that will be reprocessed during sleep.
According to research presented at the ESC 2021 Congress, drinking up to three cups of coffee a day is associated with a lower risk of stroke and fatal heart disease. This is the largest study to systematically evaluate the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease.
No, It is not true that we do not care what they think of us, that we dress in a certain way because we like it or that we do certain things just because it interests us. In reality, it is just the opposite: we care what others think of us, especially our peers. Thus, a team of researchers from UCL has developed a mathematical equation that can explain how our self-esteem is determined by what other people think of us.
According to a new study from Lund University in Sweden, there appear to be profound discrepancies in the way victims, unlike the rest of society, evaluate different types of violence. In this way, the study suggests that, in general, we have difficulties to understand the potential severity of psychological abuse and violence by women against men.
