Researchers find that the coffee pulp is valuable in its own right.
Fractal patterns are noticed by people of all ages, even small children, and have significant calming effects.
- A new study from the University of Oregon found that, by the age of three, children understand and prefer nature's fractal patterns.
- A "fractal" is a pattern that the laws of nature repeat at different scales. Exact fractals are ordered in such a way that the same basic pattern repeats exactly at every scale, like the growth spiral of a plant, for example.
- Separate studies have proven that exposure to fractal patterns in nature can reduce your stress levels significantly.
Fractal patterns are evident in nature as well as in some man-made art, architecture and sculptures.

Researchers exposed participants to images of fractal patterns (exact and statistical), ranging in complexity on computer screens.</p><p>The ages of the participants were:</p><ul><li>82 adults (between the ages of 18-33)</li><li>96 children (between the ages of 3-10)</li></ul><p>When viewing these patterns, the participants chose favorites between pairs of images that differed in complexity. When looking at exact fractal patterns, selections involved different pairs of snowflake-like or branch-like images. For statistical fractals, selections involved choosing between pairs of cloud-like images. </p><p>Although there were some differences in the preferences of adults and children, the overall trends were similar: exact patterns with greater complexity were more preferred. This study confirms that these preference trends are apparent in early childhood, suggesting that the appreciation for common fractal aesthetics is formed earlier in our development than previously thought. </p><p>Prior to this study, exposure to fractal patterns might have been expected to vary across the lifespan of a person due to environmental and developmental patterns. Instead, this study found a consistent preference across childhood and through adulthood which suggests a stable fractal aesthetic is established early in life. There is a possibility, according to this study, that an early biological or evolutionary mechanism optimizes our visual system for processing fractals. </p>
Fractal patterns can be used to significantly reduce stress<img class="rm-lazyloadable-image rm-shortcode" type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDk1OTg2OS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY3NTU0NDQ0N30.asGpAHgLrh0nZSWeZYyvYdP_yMkn-ZN8GvOWekDh9PA/img.jpg?width=1245&coordinates=0%2C618%2C0%2C6&height=700" id="4edaa" width="1245" height="700" data-rm-shortcode-id="54d01910340ccd24b3eaa7ebe79f039b" data-rm-shortcode-name="rebelmouse-image" alt="fern plant fractal pattern in nature" />
Fractal patterns and designs can reduce your stress by up to 60%, according to research.
Credit: MNStudio on Adobe Stock<p>The term "fractal" was first coined in 1975 by Benoit Mandelbrot, who discovered that simple mathematic rules apply to a vast array of things that often looked visually complex. Since then, many studies have been conducted on what fractals are, where we find them, and even how they impact us.</p><p>The study above, mentioning the positive benefits that fractals have in even small children, becomes particularly interesting when you begin to understand the potential benefits we derive from even minimal exposure to fractal patterns. </p><p><strong>Fractal patterns can reduce stress by up to 60 percent, according to <a href="https://www.psychologytoday.com/us/blog/codes-joy/201209/fun-fractals#:~:text=The%20results%20of%20many%20studies,physiological%20resonance%20within%20the%20eye." target="_blank" rel="noopener noreferrer">Psychology Today</a>. </strong></p><p>Exposure to fractal patterns in nature can reduce your stress levels significantly. It seems this kind of stress reduction most often occurs because of a certain physiological resonance within the eye. While this effect is most prominent in nature's fractal patterns, some research indicates that certain types of artwork carrying fractal patterns can also promote relaxation.</p><p><strong>How can you use fractals to feel happier? </strong></p><p>A separate <a href="https://www.psychologytoday.com/us/blog/codes-joy/201209/fun-fractals" target="_blank" rel="noopener noreferrer">Psychology Today</a> article focuses on how to use our knowledge of the positive benefits of fractals to our advantage. To take a walk in nature, visit a park or garden or sit and watch the clouds for a while, paying special attention to the patterns you see can help you include this kind of relaxation practice into your daily life. Alternatively, you can opt for a visually pleasing fractal plant (like the spiral aloe or a fern) to sit at your office desk. </p><p>Additionally, you can conduct some "research" of your own by placing yourself in fractal-rich environments for 20 minutes a day for one week and monitoring your stress levels before and after. </p>
A study finds 1.8 billion trees and shrubs in the Sahara desert.
- AI analysis of satellite images sees trees and shrubs where human eyes can't.
- At the western edge of the Sahara is more significant vegetation than previously suspected.
- Machine learning trained to recognize trees completed the detailed study in hours.

Area in which trees were located
Credit: University of Copenhagen<p>As important as trees are in fighting climate change, scientists need to know what trees there are, and where, and the study's finding represents a significant addition to the global tree inventory.</p><p>The vegetation Brandt and his colleagues have identified is in the Western Sahara, a region of about 1.3 million square kilometers that includes the desert, <a href="https://en.wikipedia.org/wiki/Sahel" target="_blank">the Sahel</a>, and the <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/subhumid-zones" target="_blank" rel="noopener noreferrer">sub-humid zones</a> of West Africa.</p><p>These trees and shrubs have been left out of previous tabulations of carbon-processing worldwide forests. Says Brandt, "Trees outside of forested areas are usually not included in climate models, and we know very little about their carbon stocks. They are basically a white spot on maps and an unknown component in the global carbon cycle."</p><p>In addition to being valuable climate-change information, the research can help facilitate strategic development of the region in which the vegetation grows due to a greater understanding of local ecosystems.</p>

Credit: Martin Brandt/University of Copenhagen<p>There's been an assumption that there's hardly enough vegetation outside of forested areas to be worth counting in areas such as this one. As a result the study represents the first time a significant number of trees — likely in the hundreds of millions when shrubs are subtracted from the overall figure — have been catalogued in the drylands region.</p><p>Members of the university's Department of Computer Science trained a machine-learning module to recognize trees by feeding it thousands of pictures of them. This training left the AI be capable of spotting trees in the tiny details of satellite images supplied by NASA. The task took the AI just hours — it would take a human years to perform an equivalent analysis.</p><p>"This technology has enormous potential when it comes to documenting changes on a global scale and ultimately, in contributing towards global climate goals," says co-author Christian Igel. "It is a motivation for us to develop this type of beneficial artificial intelligence."</p><p>"Indeed," says Brandt says, "I think it marks the beginning of a new scientific era."</p>
Looking ahead and beyond<p>The researchers hope to further refine their AI to provide a more detailed accounting of the trees it identifies in satellite photos.</p><p>The study's senior author, Rasmus Fensholt, says, "we are also interested in using satellites to determine tree species, as tree types are significant in relation to their value to local populations who use wood resources as part of their livelihoods. Trees and their fruit are consumed by both livestock and humans, and when preserved in the fields, trees have a positive effect on crop yields because they improve the balance of water and nutrients."</p><p>Ahead is an expansion of the team's tree hunt to a larger area of Africa, with the long-term goal being the creation of a more comprehensive and accurate global database of trees that grow beyond the boundaries of forests.</p>
We're in an era of 'megafires'.
A headline that reads 'The Worst Year in History for Wildfires' should be a shocking and dramatic statement. Instead, it's in danger of becoming a cliché, a well-worn phrase, an annual event.
Spending time in green spaces seems to yield many health benefits, most of which researchers are only beginning to understand.
- The longitudinal study examined the development of pairs of twins growing up in various parts of Belgium.
- The results revealed a positive relationship between growing up near greener spaces and having a higher IQ.
- The differences were especially significant on the lower end of the intelligence spectrum, suggesting that policy changes could make a significant difference in intellectual development.
Intelligence is shown in association with green space in a 3,000-m radius around the current residence in twins living in an urban (n = 232), suburban (n = 126), and a rural area (n = 254)
Pixabay<p>To be sure, the study only established a statistically significant correlation—it didn't conclude that a lack of green space causes lowered intelligence in children. Still, the researchers said their findings contribute to the growing body of research on the health risks of city living, and how green spaces factor into the mix.</p><p style="margin-left: 20px;">"There is more and more evidence that green surroundings are associated with our cognitive function, such as memory skills and attention," Tim Nawrot, a professor of environmental epidemiology at Hasselt University in Belgium, told <a href="https://www.theguardian.com/environment/2020/aug/24/children-raised-greener-areas-higher-iq-study" target="_blank" rel="dofollow">The Guardian</a>.</p><p style="margin-left: 20px;">"What this study adds with IQ is a harder, well-established clinical measure. I think city builders or urban planners should prioritise investment in green spaces because it is really of value to create an optimal environment for children to develop their full potential."</p>
