1 . While waste within the convenience economy should certainly be solved, it is neither realistic nor sustainable to work towards the complete abandonment of plastics for packaging and other convenience items. Plastics play a crucial role in preserving products both physically and from the effects of water, oxygen and other things. Further, we cannot over-rely on recycling when we consider weak market interest in low-grade materials.
What we need is a strong focus on improving the sustainability of the plastics that we will continue to need. For these plastics, the clear goal should be to stop the use of oil. We must turn to materials based on natural, renewable resources and produce plastics that have minimal impact on the environment after multiple use. Several of these products are already available on the market, but the key to challenging the dominance of oil-based plastics is extending and developing the capacity and range of such products with new material science.
Industrial biotechnology is becoming a cornerstone of the bio-economy. It involves working with natural processes to extend biochemical pathways that can be used in manufacturing (制造业). It has the potential to improve how we manufacture materials and allow us to produce entirely new materials, at the same time protecting the environment and reducing costs.
At Biome Bio-plastics, for example, our industrial biotechnology development programme has already successfully produced bio-based chemicals at sufficient scale (规模) for industrial testing from lignin, the woody material in plants and other renewable carbon sources. Availability of these chemicals could-completely transform the bio-plastics market, creating natural polymers (聚合物) that can compete with oil-based polymers on both cost and functionality. We believe that our product can deliver important changes across the materials industry and provide a critical tool in the fight against plastic pollution.

2 . A planet that suffers 475 C beneath a thick acid atmosphere may be the last place you'd expect alien (外星的) life in our solar system. But one NASA scientist claims that extraterrestrials (天外来客) are most likely hiding on Venus amid conditions that are unbearable for humans. The new theory was put forward by the research scientist Dr Michelle Thaller. She says that possible signs of life have already been seen within the carbon-dioxide filled atmosphere, adding that she was absolutely certain that life exists somewhere.
Venus is often described as Earth's twin due to its similar size and structure. But their conditions couldn't be further apart, as astronomers believe it would be impossible for humans to exist on Venus. Positioned 67 million miles from the Sun, Venus is the hottest planet in our solar system, suffering temperatures that can even melt lead. Its atmosphere also adds to the uninhabitable situation.
Despite this, scientists have long debated whether Venus' clouds may host microbial (微生物的) life forms that can survive. Many scientists think that photosynthesis (光合作用) is possible on the planet's surface as Venus receives enough solar energy to pass through its thick clouds.
However, Professor Dominic Papineau, a biologist at the University College of London, believes Dr Thaller's views are “difficult to realistically assume”. He explained, “For life-related chemical reactions to take place, liquid water is necessary. Hence, to find extraterrestrial life, we need to find liquid water, and to find extraterrestrial fossils requires looking for special rocks that were associated with liquid water in the past.”
This makes life on Venus today difficult to realistically assume, because its surface is too hot, although Venus might have had liquid water in its past. Even still, both Professor Papineau and Dr Thaller agree that the icy moons of our solar system could also be sites of potential microbial life. NASA suggests there are 290 “traditional moons” in our solar system-excluding 462 smaller minor planets.

3 . A brown and dry lawn is not something many gardeners would boast about. But that is exactly the kind of yard competition organizers in Sweden were looking for when they launched the prize for the “World’s Ugliest Lawn”. People from around the world were invited to post pictures of their dehydrated(脱水的)grass to social media in a bid to win the uncertain honor.
The intention, according to those behind the project, was to raise awareness of “saving water on a global scale by changing the norm for green lawns”. Lawns, which can require large amounts of water to maintain, are coming under increasing examination as climate change makes periods of drought more frequent and intense.
The global initiative was launched on the official website for Gotland in Sweden. “Huge amounts of water are used to water lawns for aesthetics(美学). As the world gets warmer, lack of water in urban areas is projected to affect up to 2.4 billion people by 2050. By not watering lawns for aesthetic reasons, we can protect the availability of groundwater,” the competition organizers said.
The unlikely title has been awarded to Kathleen Murray who lives in Sandford in Tasmania, Australia. According to the organizers, Murray’s lawn “boasts deep and dry divots created by three wild bandicoots(袋狸)and not one dust-covered decimeter is wasted on watering”. Murray said in the press release about her triumph, “I am terribly proud! I knew I would have my 5 minutes of fame, even if it was for having the ugliest lawn on the planet! I am now free of ever taking care of my lawn again.”
A press release by the Gotland, office added, “For the planet and its declining stockpiles of life-giving liquid, thank you, Kathleen, as well as those naughty bandicoots damaging your lawn for the greater good.” Organizers added, “Gotland aims to show to Sweden and the world that sustainable behavior doesn’t have to be dull.”

4 . Against huge odds, Shikuku Ooko is fighting to save the last remaining ancient forest. When he was in his early 20s, Shikuku Ooko was deeply taken with the Afro-Alpine forests of central Kenya. So much so that he decided to buy 15 acres of woods next to Mount Kenya National Park & Reserve. More than 30 years later Mr. Ooko’s home is one of the few plots still filled with native trees and plants. In contrast, much of the national park has been heavily logged.
The Mount Kenya region is remote and delicate, which makes it difficult to safeguard. Though the Kenya Forest Service has made sustainably managing all public forest plantations its second priority, the burden of conservation has fallen on the shoulders of local individuals such as Mr. Ooko.
In recent years, herders (牧民) have even built animal pens within legally protected areas. “It’s a bit of an annoying sight,” Mr. Ooko says, “when foreign visitors have to pay a high fee to enter the park but then come across huge herds of sheep and cattle in the delicate environment. The laws protecting that environment are in place, but they are insufficiently enforced because rangers (护林员) at each gate are limited.”.
When he’s at home in Naro Moru, Mr. Ooko advocates for tree planting, particularly among kids. “It’s something I grew up doing,” he explains. “When I was young, my dad would give all of us 10young trees to plant and take care of. Somehow, he knew the connections between trees and climate changes.”
It’s a practice Mr. Ooko has kept alive despite continuous challenges with climate and cattle; it is not uncommon for sheep and cattle to destroy the young trees that he and his young friends have planted. “We just keep going,” he says. “It’s something I value, and I think we should plant more.”

5 . Some of our planet’s power pollinators (传粉昆虫) may have originated tens of millions of years earlier than scientists once believed. In a study published July 27 in the journal Current Biology, a team of researchers traced bee family back over 120 million years to the ancient supercontinent Gondwana (冈瓦纳大陆). While looking deeper into bee history, the team found evidence that bees originated earlier, diversified faster, and spread wider than previously suspected, putting together pieces of a puzzle on the origin of these pollinators.
In the study, an international team of scientists would be in sequence and compared genes from over 200 bee species. They then compared these bees with the traits from 185 different bee fossils and extinct fossils to develop an evolutionary history and genealogical model for how bees have historically been spread around the world. The team was able to analyze hundreds of thousands of genes at a time to make sure that the relationships they inferred were correct.
“This is the first time we have broad genome-scale data for all seven bee families,” study co-author and Washington State University entomologist Elizabeth Murray confidently said in a statement. Earlier studies established that the first bees potentially evolved from wasps (黄蜂), transitioning from predators up to collectors of pollen and nectar (花蜜). According to this study, bees arose in the dry regions of western Gondwana during the early Cretaceous period, between 145 million years ago to 100.5 million years ago.
“There’s been a long-time puzzle about the origin of bees,” study co-author and Washington State University entomologist Silas Bossert said in a statement. “For the first time, we have statistical evidence that bees originated on Gondwana. We now know that bees are originally southern hemisphere insects.” The team found evidence that as new continents formed, the bees moved northward. They continued to diversify and spread in parallel partnership with flowering plants called angiosperms. The bees later moved into India and Australia and all major bee families appear to have split off from one another before the beginning of the Tertiary period (65million years ago).

6 . Climate change is causing more areas to turn into deserts. This issue is affecting the lives of 250 million people as land that used to be good for farming becomes dry and unproductive. Around one-third of the world’s land is impacted, including regions in Africa, southern Europe, Asia and America.
Sand to Green is a Moroccan company that can transform a patch of desert into a sustainable (可持续的) and profitable plantation in five years, according to Wissal Ben Moussa, its co-founder and chief agricultural officer. The solution is using agroforestry (农林业)to create a new kind of agriculture that is sustainable and that can be resilient (有适应力的) in front of climate change.
The system can be set up close to any source of salty water, which Sand to Green cleans using energy from the sun. It then grows different types of fruit trees and plants together in the same area—a method called mixed planting—and waters the plants’ roots directly with the cleaned water, to reduce water loss to the air. The soil is regenerated using what Sand to Green calls “green manure”, a mixture that includes compost, biochar(生物炭)and microorganisms that help the soil “wake up”. Biochar is a form of charcoal that can help dry soil hold on to water.
In a five-hectare trial in southern Morocco that’s been running since 2017, Sand to Green has tried out a variety of plants in search of the best performers. Among the intercropping herbs (草本植物) that have been successfully trialed are rosemary, geranium, vetiver and citronella, which Ben Moussa describes as “very low-maintenance and very high-profit”.
Sand to Green is now working to scale up to a 20-hectare commercial site, also in southern Morocco. It says a site of that size would cost around $475,000 to set up and would start bringing financial returns in about five years.
According to Ben Moussa, with this system they create biodiversity, which means better soil, healthier crops and a bigger yield. The plantation can generate 1.5 times more yield, thus making more money than a farm that grows only one type of crop in the same space.

7 . The beauty industry produces many units of one-time use containers every year. More and more consumers are asking how they can keep themselves clean and beautiful without trashing the planet.
It’s a question Women of the Future winner, Natassia Nicolao, considered during her years working in product development for beauty and wellness companies. Raised by a strong and supportive mother, Natassia used her skills and passion to make a difference. In 2021, she created her waterless beauty brand.
She said, “Water is involved in every stage of a product life cycle. Everything we use, buy, sell and make has a huge water footprint. On top of that, the beauty industry adds water as the main ingredients in its products, despite it having no direct benefit to our skin.”
Having lived through water restrictions in drought-ridden Australia, Natassia felt it necessary to stop the overuse of water in the beauty industry. Natassia has always loved beauty. Her company tries to be sustainable in every step of the way, but at its core, it is about removing water from our beauty routines.
“It’s really rooted in water conservation first, and then managing your water footprint, your carbon footprint and your waste footprint,” Natassia said. “We create waterless beauty products to help conserve water.” The glass bottles and jars of her products can be recycled. The oils and wipes are formulated without any water, requiring no water to use. The company also has a piece of game-changing beauty technology: face-wipes and masks that completely dissolve in water.
“The company is still in its beginning,” Natassia said. With the prize money from Women of the Future, she plans to purchase a machine to simplify the creation of the wipes and masks. The publicity, meanwhile, will help her spread the message central to the company’s existence that beauty must do better. Natassia believes that, with a little courage and innovation, it can do.

9 . Have you ever imagined being able to communicate with your pet at home and have it understand everything you say? It sounds too good to be true, but scientists have started using artificial intelligence (AI) to help communicate with animals.
Professor Karen Bakker—who is the author of a book called The Sounds of Life: How Digital Technology Is Bringing Us Closer to the Worlds of Animals and Plants—said that AI is already helping humans communicate with bats and honeybees and this could change what we know about nature and our non-human relationships.
Scientists have worked out how bats speak to each other to argue over food and how mother bats communicate with their young.
Professor Bakker explained how researcher Yossi Yovel had used recordings and AI to understand bats.
“Bats argue over food; they actually distinguish between genders when they communicate with one another; they have individual names, or ‘signature calls’,” she said.
“Mother bats speak to their babies in a kind of ‘motherese’.
Bats learn to ‘speak’ with signals from their mothers.
But while human mothers raise the pitch(音高) of their voices when talking to babies，mother bats lower the pitch.
She said it was a great example of how animal patterns could be revealed using sensors and microphones that would otherwise never be heard with the human ear.
AI makes this possible because a computer can be trained to listen like a bat.
With honeybees, the computer combines listening with vision of the bees’ body movements to understand what they are communicating. Researchers now know how be essay things such as “hush” or “stop”.
Researcher Tim Landgraf even created a robot honeybee that entered a hive(蜂房) and was able to communicate with other bees when it wanted them to stop doing something or fly.
