Exposure to 1-minute sound may prevent motion sickness: Japan team
KYODO NEWS - 12 hours ago - 10:10 | Japan, All People suffering from motion sickness may be able to prevent their symptoms from developing just by listening to a minute of special sound, a Japanese research team said. The research found a sound at 100 hertz stimulates the inner ear and helps to reduce motion sickness by improving balance, the team said, while current preventive measures are largely limited to taking medicines. The study comes as the risk of suffering from motion sickness is on the rise with the development of self-driving vehicle technology, as it is passengers rather than drivers that tend to develop symptoms, according to the team, which includes researchers from Nagoya University. In the experiment, around 80 volunteers were exposed to the special sound at a certain volume for one minute shortly before riding on a swing, a driving simulator and an actual car, while a similar group took part without exposure to the sound. The study showed 70 to 80 percent of those who were exposed to the sound found symptoms such as lightheadedness and nausea were alleviated, according to the findings published last month in medical journal Environmental Health and Preventive Medicine. The improvement in such symptoms is believed to have been caused by the sound stimulating the otolithic organs in the inner ear, thus activating the vestibular system, the team said. "We'd like to put (the study) into practice at an early date after carefully confirming its safety. We hope that this will be an option for people suffering from motion sickness," said Masashi Kato, a Nagoya University professor who participated in the research.

How to stop grey hair developing? Scientists may have the answer in everyday food staples
It's good news if you like eating your greens – scientists have found an antioxidant present in many vegetables that may stop grey hairs developing, according to reports. Scientists from Nagoya University in Japan have discovered from tests on mice that luteolin is an effective preventative for the common phenomenon, the Mail has reported. Professor Masashi Kato, lead author of the study, said: 'This finding suggests that luteolin may have a unique medicinal effect that prevents greying.' But, unfortunately, there is no proof that it is also a preventative for baldness. 'Interestingly, luteolin had limited effects on hair cycles, indicating that its primary impact is on pigmentation rather than hair growth or shedding,' the professor added. 'This targeted action makes luteolin a particularly intriguing candidate for addressing age-related hair greying.' Here is the breakdown. Greying is experienced by almost all of us and at different ages but will be present in significant amounts by the age of 50 in half the population. Studies have shown it often develops sooner in Caucasias than in Asian or Black people. New York University, also testing their theory with mice, found that greying happens when pigment-making cells lose the ability to mature. This means that hair does not actually turn grey per say, but just loses the ability to make pigment. Nagoya University compared luteolin to other antioxidants, hesperetin and diosmetin, by giving them to different groups of mice. The mice were already all set to go grey much like humans due to breeding but those that were exposed to luteolin showed the least amount of greying and still looked brown. Professor Kato added: 'While we expected that antioxidants may also have anti-greying effects, only luteolin, not hesperetin or diosmetin, demonstrated significant effects.' Seeking out root veg will not send you too far wrong. Luteolin is very common and can be found in celery, broccoli, carrots, onions, and peppers, according to the Mail. A winter veg soup can include many of these ingredients.
