What struck Scott Bennett most were the razor clams.

The long saltwater clams, resembling old-fashioned razors, normally burrow into sand to avoid predators. But when Bennett, an ecologist, visited South Australia’s Great Southern Reef last month, he saw thousands of them rotting on the sea floor.

“100% of them were dead and wasting away on the bottom,” Bennett told CNN.

Since March, a harmful algal bloom, fueled by a marine heat wave, has been choking South Australia’s coastline, turning once-colorful ecosystems filled with thriving marine life into underwater graveyards.

The bloom has killed about 15,000 animals from over 450 species, according to observations on the citizen science site iNaturalist. They include longfinned worm eels, surf crabs, warty prowfish, leafy seadragons, hairy mussels and common bottlenose dolphins.

The algae have poisoned more than 4,500 square kilometers (1,737 square miles) of the state’s waters – an area larger than Rhode Island – littering beaches with carcasses and ravaging an area known for its diversity.

It’s “one of the worst marine disasters in living memory,” according to a report by the Biodiversity Council, an independent expert group founded by 11 Australian universities.

The toxic algal bloom has devastated South Australia’s fishing industry and repelled beachgoers, serving as a stark warning of what happens when climate change goes unchecked.

Once a bloom begins, there is no way of stopping it.

“This shouldn’t be treated as an isolated event,” Bennett said. “This is symptomatic of climate driven impacts that we’re seeing across Australia due to climate change.”

It all started back in March, when dozens of surfers at beaches outside Gulf St Vincent, about an hour south of state capital Adelaide, reported experiencing a sore throat, dry cough and blurred vision after emerging from the sea.

Shortly after, a mysterious yellow foam appeared in the surf. Then, dead marine animals started washing up.

Scientists at the University of Technology Sydney soon confirmed the culprit: a buildup of a tiny planktonic algae called Karenia mikimotoi. And it was spreading.

In early May, the government of Kangaroo Island, a popular eco-tourism destination, said the algal bloom had reached its coastline. A storm at the end of May pushed the algae down the coast into the Coorong lagoon. By July, it had reached the beaches of Adelaide.

Diverse algae are essential to healthy marine ecosystems, converting carbon dioxide into oxygen and benefiting organisms all the way up the food chain, from sea sponges and crabs to whales.

But too much of one specific type of algae can be toxic, causing a harmful algal bloom, also sometimes known as a red tide.

While Karenia mikimotoi does not cause long-term harm to humans, it can damage the gills of fish and shellfish, preventing them from breathing. Algal blooms can also cause discoloration in the water and block sunlight from coming in, harming ecosystems.

The Great Southern Reef is a haven for “really unique” biodiversity, said Bennett, a researcher at the University of Tasmania, who coined the name for the interconnected reef system which spans Australia’s south coast.

About 70% of the species that live there are endemic to the area, he said, meaning they are found nowhere else in the world.

“For these species, once they’re gone, they’re gone.”

According to Cook, having multiple meteor showers occur at the same time is a common phenomenon. “For example, during the Perseids, you have the remnants of the Southern Delta Aquariids going on,” he said.

Right now, the Alpha Capricornids, the Southern Delta Aquariids and Perseids are all active and while the Perseids is not at its peak , you might still see some of its meteors this week. There’s also the possibility of seeing 10 to 12 meteors that aren’t associated with any of these showers, according to Lunsford.

Both the Alpha Capricornids and Southern Delta Aquariids become visible annually when Earth passes through debris fields left by two Jupiter-family comets: 169P/NEAT (Alpha Capricornids) and P2008/Y12 (Southern Delta Aquariids). Cook also noted that, each year, “we’re passing closer to the core of the material that produces (the Alpha Capricornids) shower and in 200 years, it’ll be the strongest shower that’s visible from Earth. It’ll actually produce more than 1,000 (meteor streaks) an hour, which is quite a bit stronger than it is now.”

For those interested in contributing to astronomers’ understanding of meteors, this week presents the perfect opportunity to count how many meteors you see in the night sky and report them to places like the American Meteor Society.

Upcoming Meteor Showers
Here are the other meteor showers to anticipate in 2025 and their peak dates, according to the American Meteor Society and EarthSky.

Perseids: August 12-13
Draconids: October 8-9
Orionids: October 22-23
Southern Taurids: November 3-4
Northern Taurids: November 8-9
Leonids: November 16-17
Geminids: December 12-13
Ursids: December 21-22

Lunar and solar eclipses in 2025
Two eclipse events will occur as summer ends.

A total lunar eclipse will be visible in Europe, Asia, Australia, Africa, parts of eastern South America, Alaska and Antarctica on September 7 and 8, according to Time and Date.

A lunar eclipse occurs when Earth passes exactly between the sun and the moon, throwing the latter into shadow and making it appear darker or dimmed.

When the moon sits in the darkest part of Earth’s shadow, the sun’s rays bend around Earth and refract light on the moon’s surface, which gives it a reddish hue, according to London’s Natural History Museum. Some people call the result a “blood moon.”

Two weeks after the total lunar eclipse, a partial solar eclipse will be visible in parts of Australia, the Atlantic, the Pacific and Antarctica on September 21.

Solar eclipses occur when the moon moves between the sun and Earth, blocking part of the sun’s surface from view, according to NASA. This creates a crescent shape — as if something took a “bite” out of the sun.

Emily Mazreku, director of marketing and communications at Breakthrough T1D, lives with type 1 diabetes and worked with Mattel to design the doll.

Barbie’s phone app displays a snapshot of her actual blood sugar readings from one day during the design process. Barbie’s blood glucose reading is 130 milligrams of sugar per deciliter of blood, which is in the normal range. Most people with diabetes try to keep their blood sugar between 70 and 180 mg/dl.Her continuous glucose monitor has a graph that shows the highs and lows that can happen during the day. The blue polka dots are nods to the colors and symbols for diabetes awareness.

Mazreku spent almost two years holding focus groups to get feedback about the features of the doll and to make sure it was representing the entire type 1 diabetes community.
“Mattel approached us, and they wanted this to be a part of their Fashionista line,” Mazreku said. “And we jumped on that opportunity right away.”

The line has dolls with more than 175 different looks, including a variety of skin tones, eye and hair colors. It includes a Barbie with behind-the-ear hearing aids, a blind doll who uses a cane and another with a prosthetic leg. There’s also a doll with vitiligo, a condition in which skin loses its pigment and becomes splotchy.

“We know that increasing the number of people who can see themselves in Barbie continues to resonate,” said Devin Duff, a spokesperson for Mattel, in an email to CNN.

The company said the blind Barbie and a doll with Down syndrome were among the most popular Fashionista dolls globally in 2024.
The company launched its first doll with a disability — a friend for Barbie called Share-a-smile Becky, who used a wheelchair — in 1997. Customers noted at the time that Becky’s wheelchair couldn’t fit through the doors of the Barbie Dream House, a situation many people with disabilities encounter in real life.

Rescuers are hailing as a “four-legged hero” a furry Chihuahua whose pacing atop an Alpine rock helped a helicopter crew find its owner, who had fallen into a crevasse on a Swiss glacier nearby.

The man, who was not identified, was exploring the Fee Glacier in southern Switzerland on Friday when he broke through a snow bridge and fell nearly 8 meters (about 26 feet), according to Air Zermatt, a rescue, training and transport company.

Equipped with a walkie-talkie, the man connected with a person nearby who relayed the accident to emergency services. But the exact location was unknown. After about a half-hour search, the pacing pooch caught the eye of a rescue team member.

As the crew zeroed on the Chihuahua, the hole the man fell into became more visible. Rescuers rappelled down, rescued the man and flew him and his canine companion to a hospital.

“Imagine if the dog wasn’t there,” Air Zermatt spokesman Bruno Kalbermatten said by phone. “I have no idea what would happen to this guy. I think he wouldn’t survive this fall into the crevasse.”

On its website, the company was effusive: “The dog is a four-legged hero who may have saved his master’s life in a life-threatening situation.”

Job losses
But what about the impact of tariffs on job creation? Surprisingly, an increase in import taxes has been found to result in slightly more unemployment across countries.
kraken darknet
An example provided by Irwin at Dartmouth College points to one plausible explanation — and it has to do with the steeper cost of imported goods.

“A number of studies have shown, on net, we lost jobs from the (2018) steel tariffs rather than gained jobs because there are more people employed in the downstream user industries than in the steel industry itself,” he said.

A study by the Federal Reserve Board found that a rise in input costs resulting from US tariff hikes in 2018-19 led to job losses in American manufacturing. The damage from those higher expenses was compounded by retaliatory taxes on US exports, more than offsetting a small boost to manufacturing employment from US tariffs — at least so far, the 2024 paper said.

Retaliation by other countries is indeed another danger of pulling the tariff lever. Higher tariffs on American exports would typically raise their prices for foreign consumers, hitting demand for the goods in many cases.

When Trump announced new tariffs this year, America’s major trading partners were quick to strike back with their own levies, although the US then agreed a temporary truce with China and the European Union.

Costs of free trade
While economists generally agree that free trade has benefited the global economy in recent decades, they acknowledge that it comes with certain costs.

One is the loss of jobs in communities that are particularly exposed to new competition from foreign manufacturers.

That is similar to the impact of technological progress on workers. “Manufacturing jobs as a share of the labor force have come down everywhere. It isn’t a US-specific story,” said Gimber at JPMorgan Asset Management, pointing to automation.

He drew a parallel between helping workers affected by higher imports and what is known as a just transition — the idea that the drastic changes needed to move toward a greener economy should be fair to everyone and minimize harm to workers and communities.

In both cases, providing workers in impacted industries with new skills or retraining them could be key, Gimber said.

Another potential cost of free trade is dependency on far-flung manufacturers. That took on new relevance during the pandemic, which snarled global supply chains, contributing to shortages of products such as face masks and respirators in the US and elsewhere.

However, economists do not typically see tariffs as a good way to build up domestic manufacturing, Fatas at INSEAD said, noting that subsidies for specific industries are viewed as a better tool “because they work more directly.”

But perhaps the strongest argument in favor of free trade is its importance to maintaining peace between nations.

As Gimber’s colleague David Kelly noted in March, closer trade relations give countries more to lose in any conflict.
