Six rehabilitated sea turtles were returned to the ocean off Massachusetts on Tuesday morning, July 22,  following about seven months of care for “life-threatening, hypothermia-related conditions,” according to the New England Aquarium.

The aquarium said “staff, volunteers, and interns” from its Sea Turtle Hospital in Quincy gathered on West Dennis Beach “to send off the long-term sea turtle patients,” including five critically endangered Kemp’s ridley turtles and one green sea turtle that were stranded on Cape Cod last year after becoming “cold-stunned.”

“Among the group of turtles was ‘Hercules,’ a critically endangered Kemp’s ridley, who arrived at the aquarium with sepsis and severe gastrointestinal disease. After months of aggressive treatment including tube feeding, antibiotics, and steroids, the turtle fully recovered and returned to Nantucket Sound as bystanders cheered,” the New England Aquarium wrote in a press release.

“The aquarium treated 518 live sea turtles this past cold-stunning season. As the release season in Massachusetts winds down, the aquarium continues to care for six remaining turtle patients after returning 36 turtles to Nantucket Sound this summer,” the aquarium said.

Miracle Comeback: Six Turtles Make Triumphant Return to the Ocean

A group of bumblebee catfish performed a gravity-defying display, swimming up a mini waterfall in the Aquidauana River in the central-western state of Mato Grosso do Sul, Brazil, footage captured at the end of last year shows.

The behavior was discovered when the Environmental Military Police spotted thousands of bumblebee catfish scaling up slippery rocks on November 16, 2024.

Within a week of its discovery, a team of Brazilian scientists arrived at the scene to study the rare phenomena, and subsequently published a scientific article along with the videos.

The footage shows groups of bumblebee catfish, otherwise known as Rhyacoglanis paranensis, “clustered and slowly moving upstream,” the study said.

Some of the videos also captured large numbers of the species piled onto walls, which the study described as an aggregation “so massive that specimens were seen above each other, climbing the large cluster of fish.”

Researchers concluded the bumblebee catfish were likely migrating upriver to spawn, noting that this was the first time such a migratory pattern was documented.

High on a windswept Tibetan plateau, China is building what it says will be the world’s largest solar farm — a sprawling project the size of Chicago that could power five million homes.

The facility, covering 610 square kilometres, already has panels on about two-thirds of its land. More than seven million solar panels will be installed when it’s complete, creating a vast new source of electricity in a region that until recently was mostly desert. Locals now speak of “photovoltaic sheep,” flocks grazing between rows of panels where plants have begun to take root in the shade and shelter they provide.

“In terms of production, enterprises generate electricity on the top level, and in terms of ecology, grass grows at the bottom under the solar panels, and villagers can herd sheep in between,” said Wang Anwei, head of the Hainan Prefecture energy administration.

A turning point on emissions
The giant solar farm is emblematic of China’s breakneck pace of renewable expansion. In just the first half of 2025, the country added 212 gigawatts of solar capacity — more than the entire U.S. solar fleet at the end of 2024. It also added 51 gigawatts of wind power.

That investment is beginning to show results. A study released Thursday by the Centre for Research on Energy and Clean Air found that China’s carbon emissions fell 1 percent in the first six months of 2025 compared to the same period last year, extending a downward trend that began in March 2024.

“We’re talking really for the first time about a structural declining trend in China’s emissions,” said Lauri Myllyvirta, the Finland-based analyst who authored the report. For years, drops in emissions had only come during economic slowdowns. This time, demand for electricity is still rising — up 3.7 percent so far this year — but renewable energy is growing even faster.

Li Shuo, director of the China Climate Hub at the Asia Society Policy Institute, called the plateauing of emissions “a moment of global significance.” It offers proof, he said, that a country can expand its economy while cutting emissions. Still, he cautioned that “there’s a long road ahead” given China’s ongoing dependence on coal.

Grid and coal challenges
Solar has already overtaken hydropower as China’s biggest source of renewable electricity and is on track to surpass wind this year. But integrating that power remains a challenge. Much of the renewable capacity is built in sparsely populated western provinces, while the industrial heartlands lie thousands of kilometres to the east.

To bridge that gap, China has built high-voltage transmission lines, including one linking Qinghai to Henan province, with two more planned to reach Guangdong and other manufacturing hubs.

The country’s electricity system is still structured around steady coal-fired power, which makes it difficult to accommodate the more variable supply from solar and wind. “This is an issue that the policymakers have recognised and are trying to manage, but it does require big changes to the way coal-fired power plants operate and big changes to the way the transmission network operates,” said Myllyvirta. “So it’s no small task.”

Global stakes
For now, the trend is hopeful. China, the world’s largest greenhouse gas emitter, had pledged to peak emissions before 2030. If the current trajectory continues, that peak may already have passed, years earlier than expected.

But sustaining the shift will be harder. To hit its 2060 carbon neutrality target, China’s emissions must fall by about 3 percent per year for the next 35 years. “China needs to get to that 3 percent territory as soon as possible,” Myllyvirta said.

The Tibetan plateau solar farm — vast, experimental, and symbolic — shows both the scale of China’s ambition and the challenges ahead. It is at once a striking image of transition and a reminder that the coal plants still powering much of the country remain the toughest obstacle to lasting change.

Scientists have brewed up a recipe for the finest chocolate flavor by applying scientific methods to cocoa bean fermentation. Researchers from the University of Nottingham’s School of Biosciences have pinpointed key factors that influence chocolate's taste during this crucial stage. Their findings could soon offer chocolatiers a reliable way to create consistently high-quality, flavorful chocolate.

The team explored how cacao bean acidity, temperature, and microbial communities interact during fermentation and shape the final flavor profile. They identified specific microbial species and metabolic traits linked with fine-flavor chocolate. Abiotic factors like acidity and temperature, along with biotic elements such as microbial communities, are identified as strong indicators of flavor development.

Chocolate's quality starts with the cacao bean, influenced deeply by both pre- and post-harvest conditions. Among these stages, fermentation stands out as one of the most critical steps after harvest. Fermentation sets the groundwork for aroma development, adds complexity to flavors, and reduces bitterness in the final product according to their study published in Nature Microbiology.

Dr. David Gopaulchan, the study's first author, explains that "Fermentation is a natural, microbe-driven process that typically takes place directly on cocoa farms." He describes how harvested beans are piled in boxes or baskets where naturally occurring bacteria and fungi break down the beans, producing essential compounds for taste and aroma.

However, this spontaneous process is largely uncontrolled. Farmers have limited control over which microbes dominate or how fermentation unfolds. This leads to significant variations in flavor and quality between harvests and regions.

The research team aimed to see if they could replicate this often unpredictable natural process under controlled lab conditions. Collaborating with Colombian farmers during fermentation trials helped them identify the factors most affecting flavor outcomes.

Armed with this knowledge, they devised a lab-based fermentation process using a curated mix of bacteria and fungi—essentially a defined microbial community—that could replicate traditional fermentation results. This synthetic community successfully mimicked farm fermentations and produced chocolate with similar fine-flavor characteristics.

Dr. Gopaulchan noted that their discoveries provide chocolate producers with measurable markers like specific pH levels or temperatures to predictably achieve consistent flavors: “This research signals a shift from spontaneous, uncontrolled fermentations to a standardized, science-driven process."

He further mentioned: "Just as starter cultures revolutionised beer and cheese production," cocoa fermentation is ready for transformation guided by data-driven processes tailored toward optimal flavor creation.

Their work lays crucial groundwork for future advances in chocolate production techniques globally through defined starter cultures standardizing fermentation processes while opening up new possibilities for crafting novel flavors.

By effectively domesticating aspects of this pivotal step in making high-quality chocolates around the globe can become more predictable without sacrificing unique tastes prized by consumers everywhere—a tasty prospect indeed!

Two tiny but historic arrivals have stepped into the spotlight at Yorkshire Wildlife Park: a pair of critically endangered Amur leopard cubs.

Born in May, the cubs were only the second and third of their subspecies to be born anywhere in the world this year. With just around 100 Amur leopards left in the wild, according to WWF, each new birth represents a significant step for the species’ survival.

The cubs were released this week into the park’s main reserve near Doncaster, where visitors can now watch them explore.

“The female cub is very confident and sassy like her mother, Kristen,” said Kate Borrington, senior carnivore ranger at the park. “The male cub is a little more reserved, but both have settled in nicely.”

Now past two months of age and fully vaccinated, the cubs have been allowed outside for the first time. Keepers say both wasted no time climbing to the highest points of their new enclosure. “Kristen definitely has her work cut out with these two new playful cubs, but she is doing an excellent job,” Borrington added. “It is fascinating to watch them develop and we know that they will be a firm favourite amongst visitors.”

In the wild, Amur leopards live in the border region between Russia’s Far East and northeast China, with possible sightings in North Korea. Their numbers hit a low point last century, when only about 30 individuals were thought to remain, making them the most critically endangered big cat on Earth.

Poaching, illegal wildlife trade, and deforestation — driven by global demand for timber and paper — devastated their population. Climate change has also chipped away at their forest habitat. But conservation efforts over the past two decades have given hope: their territory has expanded threefold to about 6,000 square kilometers.

Yorkshire Wildlife Park’s foundation is among the organizations backing the fight to save the Amur leopard. The group supports initiatives like WildCats Conservation Alliance, which promotes breeding, population monitoring, and habitat protection.

For now, the new cubs are keeping their mother busy and delighting the public. Their presence, park officials say, is also a reminder of just how precarious — and important — the future of their species remains.

A British police force has become the first in the country to test a robot dog designed to help officers track suspects and assess dangerous situations.

Nottinghamshire Police confirmed the robo-dog, which can climb stairs, see in the dark and move in complete silence, began a three-month trial this week. If successful, it could be deployed across the UK as soon as next year.

The four-legged machine is equipped with thermal imaging cameras, a LiDAR scanner that maps its surroundings using lasers, and an AI system capable of recognising weapons such as guns, knives, and baseball bats. It also carries a loudspeaker, allowing officers to issue remote commands, and can haul supplies into places inaccessible to drones or people.

“It can be used like a land-based drone and is equipped with several cameras, which could prove an asset to officers,” said designer Nathan Wallace, 22, from Gedling in Nottinghamshire. “We have an AI camera which can detect weapons… and a LiDAR system which can go into a room and immediately scan its surroundings.”

The machine’s design allows it to scramble over tree stumps off-road and enter buildings where traditional drones cannot fly. Police say it could be particularly useful in armed sieges, hostage situations, or incidents involving chemical or biological threats, where reconnaissance is needed without risking human lives.

Superintendent Louise Clarke said the potential was clear even at this early stage. “While still in its infancy, it is not hard to see how this technology can and will be used in the future to protect and serve the public,” she said.

“In the right circumstances, this equipment can enhance officer and public safety but will always complement the appropriate deployment of armed officers to safeguard the public. By doing so, we can gather vital intelligence about a volatile situation without putting lives at risk.”

The trial is being funded by the Office of the Chief Scientific Adviser. If the results are positive, other forces could begin using the technology in 2026.

Police stressed that there were “absolutely no plans” to arm the robo-dog and said it would not replace traditional police dogs, which remain essential for duties such as tracking scents and community policing.

Clarke said the force was “delighted to be asked to examine and stress test this very impressive new technology,” adding, “It is really exciting to be at the forefront of what could be a revolution in policing technology.”

The WNBA has set a new single-season attendance record, drawing more than 2.5 million fans to games so far this year, the league announced Thursday.

The milestone was reached after 226 games involving 13 teams. The previous record was set in 2002, when 16 teams played 256 games, highlighting how quickly the league has grown despite a smaller schedule and fewer franchises.

“WNBA sets an all-time attendance record with 2,501,609 fans as of 8/20/25,” the league’s communications team posted on X.

The surge in attendance is the latest sign of the sport’s rising popularity. In June, WNBA Commissioner Cathy Engelbert pointed to “increasing public demand for women’s basketball” as she unveiled ambitious expansion plans.

The league will add five new teams by 2030, growing from 15 franchises next year to 18. The Toronto Tempo and Portland Fire are set to debut in 2026. If approved by the WNBA and NBA Boards of Governors, teams in Cleveland, Detroit, and Philadelphia will follow in 2028, 2029, and 2030.

“The demand for women’s basketball has never been higher, and we are thrilled to welcome Cleveland, Detroit, and Philadelphia to the WNBA family,” Engelbert said in a statement. “This historic expansion is a powerful reflection of our league's extraordinary momentum, the depth of talent across the game, and the surging demand for investment in women's professional basketball.”

The record-breaking season continues a string of milestones for the league, which has seen increased television ratings, higher sponsorship investments, and bigger arenas filled with fans. With expansion on the horizon, the WNBA appears poised to keep growing its reach — and its audience.

Archaeologists on the Indonesian island of Sulawesi have uncovered stone tools dating back at least 1.04 million years, dramatically extending the timeline of early human presence in the region.

The discovery, published in Nature earlier this month, suggests that hominins—members of the human lineage—reached Sulawesi hundreds of thousands of years earlier than previously thought. Until now, the oldest known tools from the island dated only to around 194,000 years ago.

The team, led by Budianto Hakim of Indonesia’s National Research and Innovation Agency and Adam Brumm of Griffith University in Australia, found seven sharp-edged stone flakes at the site of Calio in southern Sulawesi. The artifacts were uncovered in sediments alongside a fossilized pig tooth. Dating of the surrounding sandstone and fossil placed the tools between 1.04 and 1.48 million years old.

“We don’t know what they were doing with these sharp-edged flakes of stone, but most likely they were cutting or scraping implements of some kind,” Brumm told National Geographic.

The findings place Sulawesi in the same early timeline as the nearby island of Flores, where tools and fossils of Homo floresiensis—nicknamed the “hobbit”—have been dated to about 1.02 million years ago. That raises a major question: who made the Sulawesi tools?

No early human fossils have been found on the island. The oldest skeletal evidence so far is a modern human jaw fragment only 25,000 to 16,000 years old. Still, experts suspect Homo erectus, a species known to have lived in Southeast Asia at the time, may have made the crossing.

That raises yet another mystery: how did they get there? The distances between mainland Asia and Sulawesi were far too great to swim, and hominins likely had no seafaring technology. Researchers propose that accidental “rafting”—clinging to vegetation mats or being swept out to sea during events like tsunamis—may have brought small groups across.

“It may have been some sort of freak geological event … washing some hominins out to sea clinging to floating trees or vegetation mats of some kind, and then winding up on these islands,” Brumm told New Scientist.

If Flores gave rise to Homo floresiensis, hominins on Sulawesi may have followed a different evolutionary path. On a much larger island with different resources, they may have remained closer to Homo erectus—or transformed into something else entirely.

For now, the Sulawesi tools are a tantalizing clue. They suggest early humans were making risky sea crossings far earlier than once believed, and that Wallacea—long seen as a barrier—was actually part of humanity’s ancient frontier. The next step, archaeologists say, is to find the toolmakers themselves.

Most people expect a delivery driver to drop off a package and move on. In one Brisbane suburb, however, a courier made headlines for saving more than just a parcel.

Last Thursday, Gurpreet Singh was on his route in Logan, south of the city, when a sudden downpour rolled in. As he approached a home, he noticed bed sheets hanging on a clothesline. Instead of ignoring them, Singh quickly took them down and tucked them under cover, keeping them dry.

The act, caught on a security camera, left homeowner Verrity Wandel stunned.

“I thought I was coming home to find my wash soaking wet but NO,” she wrote on social media, posting the video of Singh’s good deed.

The clip spread rapidly online, with thousands praising Singh for a small kindness that many said restored their faith in delivery drivers often criticized for being careless.

Wandel described her shock on Australian breakfast television. “I just had visions of my washing being wrapped round and round the line, or embedded in the garden, and I drove in and there was no washing on the line. And I thought, that’s odd.”

Singh himself seemed surprised by the attention. The whole thing, he said, only took “one minute.”

For Wandel, that minute was enough to turn what could have been a soggy mess into a bright reminder that even in a downpour, a little thoughtfulness can go a long way.

This Everyday Gesture by an Australian Postman Is Melting Hearts Worldwide

A retired couple in Worcestershire has struck green gold after their rare prehistoric Wollemi pine produced seeds for the first time—potentially worth tens of thousands of pounds.

Pamela and Alistair Thompson, both 75, planted the tree in their garden in Wichenford back in 2010 after buying an 18-inch sapling for just $70. Fourteen years later, the tree now stands more than four metres tall and has begun bearing cones packed with valuable seeds.

Wollemi pines, often called “dinosaur trees,” date back more than 90 million years and were thought to have gone extinct alongside the T-Rex. That changed in 1994, when a small cluster was discovered in a remote canyon west of Sydney, Australia. Since then, limited numbers of saplings have been sold worldwide to help protect the critically endangered species.

Pamela said she had been keeping an eye on the cones all summer. “A few days ago I reached up to a female cone and the seeds all cascaded into my cupped hands as I touched it,” she said. “It was very exciting actually collecting the seeds from such an ancient tree that lived when dinosaurs roamed.”

So far, five large cones have each produced around 100 seeds, with more cones still developing. At up to $10 per seed, the couple’s haul could be worth thousands. But instead of cashing in at premium prices, the couple say they plan to sell small bundles cheaply online, donating proceeds to charity.

“I saw a small tree for sale for more than $1,000 which shows just how rare they are,” Pamela said. “We are planning to package the seeds into bundles of five or six and sell them for about £5. We’d want to make them accessible for people as well as raise money for charity.”

Her husband Alistair, a retired spinal surgeon, joked: “It really does prove that money can grow on trees!”

The couple hopes their seeds will not only raise funds but also help spread Wollemi pines across the UK, supporting conservation of one of the world’s rarest tree species.

With three grandchildren of their own, Pamela said she likes the idea of leaving behind a legacy that could still be standing millions of years from now. “We don’t yet know how many seeds will produce healthy trees—only time will tell. But it would be lovely to see just how many we can grow.”

How a Prehistoric Tree in One Couple's Yard Is Sprouting Seeds Worth Thousands

At California’s newest national monument, hikers, bikers, and cows are learning to share the trails—with help from some high-tech collars.

The Cotoni-Coast Dairies monument, a 5,800-acre coastal site north of Santa Cruz that opened to the public on August 16, has long hosted cattle from local ranches under federal grazing leases. To make sure cows and people can safely coexist, the Bureau of Land Management (BLM) is piloting “virtual fencing”—a GPS-powered collar system that keeps cattle away from trails and sensitive areas without the need for miles of barbed wire.

Nearly 100 cows have been fitted with solar-powered collars developed by New Zealand-based company Halter. Ranchers use a mobile app to set invisible boundaries on the landscape. If a cow crosses the line, its collar emits a beep, then a vibration, and finally a mild shock. The animals quickly learn to respond, allowing ranchers to guide them toward or away from specific areas.

“It’s a more affordable and efficient alternative to physical fencing,” said Zachary Ormsby, BLM’s Central Coast field manager, noting that traditional fences can cost tens of thousands of dollars and obstruct scenic views. The collars cost $72 per year per animal, plus an upfront equipment fee.

The system gives cattle plenty of room to roam, while protecting visitors and fragile habitats. Land managers can even direct herds to graze in areas where they help control weeds or reduce fire risks.

The project is funded by the Foundation for America’s Public Lands and is currently being tested with the Pastorino family, who have grazed cattle on the property for 25 years. If successful, it could expand to more herds across the monument.

In addition to managing grazing, crews and volunteers have already built nine miles of multiuse trails—part of a planned 27-mile network, including wheelchair-accessible routes. The area also protects archaeological sites linked to the Cotoni people, the land’s original inhabitants.

“It’s just kind of unrivaled, in my opinion, and offers something completely new to visitors,” said Katy Peterson of the Santa Cruz Mountains Trail Stewardship, which helped construct the trails.

With virtual fences guiding cows and open trails welcoming people, Cotoni-Coast Dairies may become a model for balancing conservation, ranching, and recreation on shared public lands.
