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.”

Ruby Williams’ birthday was not your average 18th. She celebrated it on the Klamath River, with a group of young people making a historic journey paddling from the river’s headwaters in southern Oregon to its mouth in the Pacific Ocean, just south of Crescent City, California. It marked the first time in a century that the descent has been possible, after the recent removal of four dams allowed the river to flow freely.

Williams, together with fellow paddler Keeya Wiki, 17, spoke to CNN on day 15 of their month-long journey, which they are due to complete on Friday. At this point, they had just 141 miles (227 kilometers) of the 310-mile (499 kilometer) journey left to go and had already passed through some of the most challenging rapids, such as those at the “Big Bend” and “Hell’s Corner” sections of the river.

Both were exhausted and hadn’t showered in days — although they promised they “aren’t completely feral.” However, despite tired minds, they were steadfast in their commitment.
“We are reclaiming our river, reclaiming our sport,” said Williams.

“We are getting justice,” Wiki, who is from the Yurok Tribe, added. “And making sure that my people and all the people on the Klamath River can live how we’re supposed to.”

The Klamath River runs deep in the cultures of the native peoples living in its basin, who historically used dugout canoes to travel along it. They view it as a living person, a relative, who they can depend on — and in turn protect.

“It’s our greatest teacher, our family member,” said Williams, who is from the Karuk Tribe, which occupies lands along the middle course of the Klamath. “We revolve ceremonies around it, like when the salmon start running (the annual migration from the sea back to freshwater rivers to spawn), we know it’s time to start a family.”

Historically, it was also a lifeline, providing them with an abundance of fish. The Klamath was once the third-largest salmon-producing river on the West Coast of the US. But between 1918 and 1966, electric utility company California Oregon Power Company (which later became PacifiCorp), built a series of hydroelectric dams along the river’s course, which cut off the upstream pathway for migrating salmon, and the tribes lost this cultural and commercial resource.
For decades, native people — such as the Karuk and Yurok tribes — demanded the removal of the dams and restoration of the river. But it was only in 2002, after low water levels caused a disease outbreak that killed more than 30,000 fish, that momentum really started to build for their cause.

Twenty years later, the Federal Energy Regulatory Commission finally approved a plan to remove four dams on the lower Klamath River. This was when Paddle Tribal Waters was set up by the global organization Rios to Rivers to reconnect native children to the ancient river. Believing that native peoples ought to be the first to descend the newly restored river, the program started by teaching local kids from the basin how to paddle in whitewater. Wiki and Williams were among them — neither had kayaked before then.

Sky-gazers may get a good chance to see fireballs streak across the night sky this week. Two meteor showers — the Alpha Capricornids and Southern Delta Aquariids — will reach their peak and another is ramping up.
[url=https://kra36at.com]kra36 сс[/url]
The Alpha Capricornids meteor shower, which is best known for producing very bright meteors called fireballs that may look like shooting stars, will be most visible at 1 a.m. ET Wednesday, according to Robert Lunsford, fireball report coordinator for the American Meteor Society. Its radiant — the point at which the meteor streaks seem to originate — is in the Capricorn constellation.
https://kra---36-at.ru
kraken36.at
The Alpha Capricornids are visible all over the world but are usually best seen from the Southern Hemisphere, in places such as Australia and Africa, according to Bill Cooke, the lead for NASA’s Meteoroid Environments Office. These meteors are expected to appear at a rate of three to five per hour. If you are viewing from the Northern Hemisphere, keep your eyes low along the southern sky to catch a glimpse.

If you stay up later, you’ll be able to see the Southern Delta Aquariids reach peak activity at 3 a.m. ET on Wednesday, said Lunsford. The Southern Delta Aquariids, which also are most visible in the Southern Hemisphere, make for a stronger shower than the Capricornids; people located in parts of the Northern Hemisphere such as the US can expect to view up to 10 to 15 meteors per hour, while those in the Southern Hemisphere may see 20 to 25 per hour.
The Aquariids appear to stream from the southern part of the Aquarius constellation, which is around 40 degrees east of the Capricorn constellation, according to Lunsford: “They’re going to kind of do a battle, shooting back and forth at each other.”

Both showers will be visible through August 13, though there is some disagreement about the date on which their peaks will occur. While experts at the American Meteor Society say peak activity will occur Tuesday night into early Wednesday morning, those at NASA say it will happen Wednesday night going into Thursday.

“The time of a meteor shower peak is not constant from year-to-year. It can vary by plus or minus a day or two,” Cooke said.

But missing the peak, according to Lunsford, is nothing to fret about. “It’s not a real sharp peak …You can go out (on) the 31st or the 29th and see pretty much the same activity.”

For the best viewing, avoid areas with bright lights and objects that could obscure your view of the sky, such as tall trees or buildings. Picking a spot with a higher altitude, like a mountain or hill, may make it easier to spot these showers.

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.

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.

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.
tripscan войти
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.”

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