Listening to classical music helps students in their studies
Poor sleep for students usually impairs the memory-strengthening process needed to remember learning materials better. U.S. scientists offer a solution to this problem – the so-called restoration of targeted memories or reactivation during sleep.
The experiment involved 50 students aged 18 to 33 years. Participants listened to a mathematics-based microeconomics lecture while listening to various classical music (Beethoven, Chopin and Vivaldi).
After falling asleep in a sleep lab, one part played classical music for about 15 minutes during deep sleep (determined by electrodes attached to the head) and the other part played background noise.
The next day, all students had a test. It turned out that the test results were 18% better for those who, while in a deep sleep, listened to classical music at night.
The effect was particularly pronounced in participants who showed increased activity (theta waves) in the frontal lobes of the brain during deep sleep.
Listening to music at night more than doubled the chances of passing the test. However, when students performed a similar test after nine months, the effect turned out to be not lasting.
The results fell by 25%. This leads scientists to believe that the effect of this method of strengthening memory is not long-lasting. However, students can use classical music to prepare for exams.
This discovery will help improve the treatment of periodontitis
German scientists have proven for the first time that the single-celled parasite amoeba Entamoeba gingivalis. Which is often found in the human mouth, plays an important role in cases of inflammation and destruction of dental tissue.
Most of the patients studied with severe and recurrent periodontitis had a higher number of these amoebas. Once the parasite has invaded the gum tissue, it feeds on the cells and causes the tissue to break down.
Periodontitis is an inflammation of the tissues that support the gums and teeth. If left untreated, it can lead to tooth loss. The disease also increases the risk of developing arthritis, cardiovascular disease and cancer.
The researchers showed that inflammation of the mouth was linked to the growth of the parasite which was found in 80% of patients with periodontitis (compared with only 15% in healthy people).
Scientists have observed that the amoeba destroys the gum tissue, allowing bacteria to enter it, which makes the situation worse.
The effect of treatment for periodontitis in patients is often short-lived, possibly because of an unnoticed amoebic infection. Researchers believe that the new discovery will help find new long-term treatment options.
They confirmed loss of smell and taste as COVID-19 symptoms
We have associated loss of smell and taste with COVID-19 infection for some time. A study by US scientists published on April 12 confirmed this with empirical observations in practice.
Scientists conclude that if a person has a loss of smell or taste, they are 10 times more likely to have coronavirus. Doctors emphasize that we should consider these signs as a sign of early infection. U.S. researchers surveyed 1,480 patients with flu-like symptoms who performed tests with concerns about a potential COVID-19 infection.
102 of these patients tested positive. The study included responses from 59 COVID-19 positive patients (68% with odor and 71% with a loss of taste) and 203 coronavirus negative patients.
The study found that sensory disturbances were common in COVID-19. Patients reported severe odor and taste loss. However, specialists observed that they returned relatively quickly (within two to four weeks) after feeling infected. This coincided with a time of recovery.
