Researchers from Tel Aviv University (TAU) have studied free-ranging fruit bats in a colony in Egypt to answer the long-standing question of whether animals have complex cognitive abilities previously thought to exist only in humans.
The study focused specifically on mental time travel, episodic memory, delayed gratification and planning ahead, a press release from TAU said.
“For many years, the cognitive abilities to recall personal experiences (episodic memory) and plan ahead were considered exclusive to humans. But more and more studies have suggested that various animals also possess such capabilities, but nearly all of these studies were conducted under laboratory conditions, since field studies on these issues are difficult to perform. Attempting to test these abilities in wild animals, we designed a unique experiment relying on the colony of free-ranging fruit bats based in TAU’s I. Meier Segals Garden for Zoological Research,” said Dr. Yossi Yovel, a lead researcher of the study and a professor in TAU’s School of Zoology and Sagol School of Neuroscience, in the press release.
The study, “Time-mapping and future-oriented behavior in free-ranging wild fruit bats,” was published in the journal Current Biology.
“Episodic memory is the memory of our individual experiences. In animals, people talk about episodic-like memory which is the ability to remember what-where and when an event happened. We show that bats remember how much time (when) passed since they visited a specific tree (what) at a specific location (where),” Yovel told EcoWatch in an email.
The research team surmised that bats who depend on fruit trees to survive would need to develop the ability to track food availability both spatially — where trees are located — and across time — when each tree produces fruit.

“We think that fruit bats map time in order to keep track of available fruit. For example, they know that if two weeks have passed since their last visit to one kind of tree, then there will be no food on that tree, but if only one week passed there might still be food. We show that they plan their visits according to such reasoning,” Yovel told EcoWatch.
To navigate landscapes with numerous nectar and fruit trees, the bats would also need to be able to mentally track resources so that they could revisit them at the right time.
The research team tested their hypothesis by attaching a small high-resolution GPS tracking device to each bat. This enabled them to document the bats’ flight routes as well as the trees they visited for many months. The team then analyzed the data they had compiled.
The first question the researchers asked was, “Do bats form a time map in their minds?”
In order to explore this issue, they prevented the bats from venturing outside their colony for varying time periods — from one day to an entire week.
“We wanted to see whether the bats could tell that time had elapsed and behave accordingly. We found that after one day of captivity, the bats would return to trees visited on the previous night. However, when a whole week had gone by, the older bats, based on past experience, avoided trees that had stopped bearing fruit in the interval,” said lead author of the study Dr. Lee Harten from the School of Zoology and Sagol School of Neuroscience in the press release. “In other words, they were able to estimate how much time had passed since their last visit to each tree, and knew which trees bore fruit for a short time and were no longer worth visiting. Young, inexperienced bats were unable to do this, indicating that this is an acquired skill that must be learned.”
“We suggest that [the bats’] reliance on food that is distributed in both time and space is the basis for developing spatio-temporal memory,” Yovel told EcoWatch.
The second pair of questions the research team asked was, “Do the bats exhibit future-oriented behaviors? Are they capable of planning ahead?”
To explore these issues, the team observed the route each bat took to the first tree they visited in the evening, which could indicate plans made before they left the colony.
“We found that usually the bats fly directly to a specific tree they know, sometimes 20 or 30 minutes away. Being hungry, they fly faster when that tree is further away, suggesting that they plan where they are heading. Moreover, focused on their chosen target, they will pass by other trees, even good sources visited just yesterday — indicating a capacity for delayed gratification. We also found that the first bats to leave the colony choose trees bearing fruits rich in sugar, while the bats that leave later seek proteins,” said co-author of the study Chen Xing, also with the School of Zoology, in the press release.
The findings of the study suggested that the bats planned their foraging before they left the colony and knew exactly where they were flying and the type of nourishment they were looking for.
“The cognitive gap between humans and animals is one of the most fascinating issues in science. Our study demonstrates that fruit bats are capable of quite a complex decision-making process involving the three questions indicative of cognitive abilities: Where? (each tree’s location); When? (when the tree bears fruit); and What? (the nourishment it provides — sugar vs. proteins),” Yovel said in the press release. “Once again, we find that the gap is not clean-cut, and that humans are not as unique as some might think. Apparently, humans and animals are all located on a spectrum, with almost any human ability found in animals as well.”
Yovel and the research team have plans for the further study of bats’ cognitive capabilities.
“We would really like to study their spatio-temporal memory over years. We also hope to examine how such memories are encoded in their brain,” Yovel told EcoWatch.
Based on the findings of the recent study, should humans reevaluate how they look at the cognitive abilities of bats and other animals?
“Depends on which humans,” Yovel said with a smile. “In my lab we never underestimated bats, but yes – many people think that bats and animals in general are simple instinct-based machines. That is clearly wrong. Animal cognition should be thought of as a continuum. In many cases humans are on one edge of this continuum but they are never alone.”

Curating a conscious home is a thoughtful process involving much consideration — who made my products, how they were made, and what are they made from — and this guide aims to support you on your journey towards finding ethical and sustainable home decor you truly love.
What is Sustainable Home Decor?
Sustainable home decor includes any home decor that is made in a way that takes into consideration both the makers and the planet. Sustainable home decor will be ethically made using eco-friendly and natural materials. Eco-friendly decor will also be produced using sustainable supply chain practices. This includes using renewable energy and recycled or compostable packaging.
While there are numerous sustainable home decor brands, some of which are featured below, first consider what’s already been made in order to prevent contributing to new waste. Secondhand, used, or DIY home decor options are typically more sustainable than buying new.
What is Ethical and Fair Trade Home Decor?
Ethical and Fair Trade home decor is produced in a way that adheres to Fair Trade standards and is, ideally, Fair Trade Certified. Fair Trade means paying artisans and makers a fair, living wage and providing ethical working conditions. Ethical home decor also includes supporting goods made by artisans using traditional heritage techniques and art forms. Many cultures around the world are at risk of losing their age-old artisanal crafts forever in the age of mass manufacturing.
It’s important to note that sometimes a major brand may use an “eco” fiber while still supporting irresponsible labor practices, and excessive production amounts that inevitably lead to a lot of waste. This is not true sustainability in my mind!
Most artisan-made home decor is ethically produced and directly supports the makers. However, it’s important to check if a brand or marketplace is transparent about their business practices to ensure they are ethical or Fair Trade.
Where Can You Find Sustainable Home Decor?
In terms of environmental sustainability, looking secondhand and vintage is always a great first place to look for sustainable home decor.
But if you’ve scoured those options and haven’t found what you’re looking for and/or if you’re looking to financially support artisans and traditional crafts around the globe, this shopping guide is designed for you. You’ll discover many brands with artfully designed and artisan handmade goods for furnishing any space among this list of decor brands.
All of the brands in this guide use natural and/or recycled fibers and avoid the use of virgin synthetics like polyester; however, some brands do use materials that are not the most environmentally-friendly option on the market, such as conventional cotton.
And of course, I wanted to choose brands that followed slow, thoughtful production practices, prioritizing artisan handmade over factory labor and quality over quantity.
So without further ado, here are my favorite small-batch, artisan-made, and ethical home decor brands.

Take a look at why hemp is heralded as a hero material and discover 14 hemp clothing brands that have tapped into its sustainable potential.
The exploration of fabrics has always been a starting point for sustainable innovation in fashion. After all, fabrics provide tangible proof that change is possible while having a direct impact on the environment in one way or another. Plus fabrics are responsible for an outsized proportion of a fashion brand’s carbon footprint and overall environmental impact, including biodiversity loss and pollution.
So, What is Hemp Fabric?
Hemp is a bast fiber produced from the cannabis sativa plant, where every part of the plant can be utilized for over 25,000 industrial uses including clothing, biofuel, bricks, paper, and textiles.
Contrary to its popular association, hemp is actually the sober sister to marijuana. Unlike its recreational sibling that’s grown for its psychoactive THC (tetrahydrocannabinol) properties, hemp contains less than 0.3% THC, a value that was the driving force behind the legalization of hemp production in the 2018 Farm Bill. So while you can’t really get high from hemp, you can definitely enjoy its material benefits — which are plenty!
What is Hemp Clothing?
The simple answer is that hemp clothes are garments made from hemp fabric! But the important caveat here is that most hemp clothes on the market today are not made from 100% hemp fabric. They are usually blended with other fibers, like cotton.
At this point, hemp fabric manufacturing is not at the scale or technological level that the manufacturing of cotton (the most popular natural material) is, making 100% hemp clothing more expensive to produce. Also, pure hemp fabric is also known to be quite stiff until a couple dozen washes later, so blending it with a fiber like cotton can make it softer and easier to wear on the offset.
100% hemp fiber content clothing does exist, it’s just rare at this point. Though we do think this will change with more sustainable material investment happening in the textiles industry.
Is Hemp Clothing Comfortable?
It depends! The softness of hemp clothing will vary based on how the fabric was produced and if it is blended with other fibers like cotton or lyocell. Pure hemp clothing can be rougher than cotton, but hemp is known to get softer with every wash.
Also, since hemp is a natural bast fiber that comes from the softer parts of the plant’s stalk or stem, it is softer than the coarser leaf fibers.
Can Hemp Clothing Protect From The Sun?
A lesser known benefit of hemp clothing is that it can reportedly even help shield you from harmful UV rays. According to skin cancer research, a fabric’s UPF (Ultraviolet Protection Factor) value is a number that coincides with the fraction of UV rays it allows to pass through and hit your skin — the higher the UPF number, the better the protection.
Research claims that hemp has a UPF of >50 (according to European standards) due to natural pigments and lignin within the fibers, which act as UV absorbers.
Is Hemp Clothing Sustainable?
There are a lot of benefits to hemp clothing. But don’t just take our word for it, we’ve listed some of hemp’s most impressive sustainable qualities below:
1. Hemp is not resource-intensive
Hemp can be grown under a variety of agricultural and ecological conditions and has a capacity to grow rapidly.
Hemp clothing vs. cotton: With a high yield of 250% more fiber than cotton, hemp requires less land to grow, has no need for harmful pesticides or chemicals, and needs as little as 1/3rd of the water compared to conventional cotton. (Though individual use cases may vary based on the region that each of the crops are grown.)
2. Hemp is a restorative plant
Growing hemp can also help contribute to the maintenance of soil quality, courtesy of its anchored roots which prevent soil erosion and nutrient loss.
In fact, research shows that hemp can be used to restore contaminated soils through ‘phytoremediation’ — a process that has proven successful in the early 90s when industrial hemp was planted in some of the polluted Ukrainian regions near the Chernobyl disaster where much of the land was rendered useless. The experiments showed that hemp helped remove radioactive elements from the soil.
3. Hemp can absorb carbon more than other plants
Hem can act as a carbon sink. According to a Cambridge University researcher, a hectare of hemp can absorb between 8-15 tonnes of CO2, giving hemp plants a vital role in reversing carbon emissions.
