Scientists discover a surprisingly simple way to turn coffee waste into fuel
Scientists have developed an efficient method to transform used coffee grounds into a potential source of biodiesel while preserving the leftover material for other renewable fuels and valuable chemicals. The discovery could turn millions of tons of discarded coffee waste into a surprisingly useful resource for sustainable energy.
A daily schedule may help older adults feel less pain and depression, even if they struggle with sleep, according to a study from the University of Missouri. The researchers found that participants who kept consistent daily routines, such as waking up, eating, and going to bed at the same times, experienced lower levels of physical pain and depressive symptoms, regardless of their sleep quality.
This suggests that maintaining regular habits throughout the day may help regulate the body's internal clock, also known as the circadian rhythm. The circadian rhythm is our body's natural 24-hour timing system that influences when we feel awake or sleepy and affects various biological processes. When this system is aligned with regular cues like eating and sleeping, it can lead to better overall health.
The study, led by assistant professor Eunjin Tracy, involved surveying 67 older adults, 37 of whom reported insomnia. While those with insomnia generally had more pain and depression, those with consistent routines still reported fewer symptoms. This indicates that daily routines could help maintain healthy circadian rhythms even in the presence of sleep difficulties.
