An experiment conducted by the University of Tsukuba on 24 healthy young adults examined the effects of low-intensity exercise on the brain.
Neuroscientists from the University of Tsukuba in Japan determined that even just a 10-minute run at an extremely slow pace close to walking speed activates the decision-making center of the brain, enhancing mental alertness and mood.
Researchers had 24 healthy young adults run on a treadmill for 10 minutes at a low average speed of 3 to 6 kilometers per hour. While the participants' pulses remained in the range of 104 to 107 beats per minute, oxygenated blood levels on the brain surface were monitored with special sensor heads.
Compared to ten minutes of sitting still, participants' reaction times in attention and self-control tests were found to be significantly faster after a short jog. In the measurements, it was determined that the oxygen-rich blood flow to the left prefrontal cortex region of the brain, which manages both emotional state and high-level decision-making and planning processes, increased. Participants were reported to feel more alert, fit and enjoyable after exercise.
RHYTHMIC HEAD MOVEMENT STIMULATES THE BRAIN MECHANICALLY
Scientists pointed out that the result obtained may be related to the rhythmic up-down movement of the head during running. It was determined that the head acceleration that occurs while taking slow steps mechanically stimulates the brain tissue and has a direct share of 17 percent in the increase in exercise-related pleasure.
Experts say that intense, tiring or high-tempo training is not necessary to benefit from the benefits of running for the brain and mental health; He emphasized that even a few minutes of low-tempo movement is enough to revitalize brain functions.

Oxygen-free and hypersaline death pools were discovered 2 km below the sea floor in the Red Sea. These pools, which are fatal to living things, may shed light on the origin of life and new drug development studies.

Astronaut photographs showed that the switch to LED technology in street lighting changed the appearance of cities such as Miami and Las Vegas from yellow to white.

A study conducted in the US state of Florida revealed that blacktip sharks can hear low-frequency sounds 75 meters away and find the direction of the sound.

Samples obtained from the Noah's Ark Research Project at Sivas Cumhuriyet University will be analyzed in the laboratory of Ankara University. Andrew Jones said that underground structures were detected in radar scans and an increase in organic matter density was noted in soil surveys in 2024. The new samples will be searched for signs of decayed wood and human activity.
