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.”

The levies are also likely to reduce America’s economic output, as has happened before. A 2020 study, based on data from 151 countries, including the US, between 1963-2014, found that tariffs have “persistent adverse effects on the size of the pie,” or the gross domestic product of the country imposing them.

There are a number of possible explanations for this.
One is that, when tariffs are low or non-existent, the country in question can focus on the kind of economic activities where it has an edge and export those goods and services, Gimber told CNN.

“If you raise tariffs, you’re not going to see that same level of specialization,” he said, noting that the result would be lower labor productivity. “The labor could be better used elsewhere in the economy, in areas where you have a greater competitive advantage.”
Another reason output falls when tariffs are raised lies in the higher cost of imported inputs, wrote the authors of the 2020 study, most of them International Monetary Fund economists.
Fatas at INSEAD suggested the same reason, providing an example: “So I’m a worker and work in a factory. To produce what we produce we need to import microchips from Taiwan. Those things are more expensive. Together, me and the company, we create less value per hour worked.”
Yet another way tariff hikes can hurt the economy is by disrupting the status quo and fueling uncertainty over the future levels of import taxes. That lack of clarity is particularly acute this year, given the erratic nature of Trump’s trade policy.
Surveys by the National Federation of Independent Business in the US suggest the uncertainty is already weighing on American companies’ willingness to invest. The share of small businesses planning a capital outlay within the next six months hit its lowest level in April since at least April 2020, when Covid was sweeping the globe.
“The economy will continue to stumble along until the major sources of uncertainty (including over tariffs) are resolved. It’s hard to steer a ship in the fog,” the federation said.
Whichever forces may be at work, the IMF, to cite just one example, thinks higher US tariffs will lower the country’s productivity and output.

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.

Musk recently announced Grok would be “retrained” after he expressed displeasure with its responses. He said in late June that Grok relied too heavily on legacy media and other sources he considered leftist. On July 4, Musk posted on X that his company had “improved @Grok significantly. You should notice a difference when you ask Grok questions.”

Grok appeared to acknowledge the changes were behind its new tone.
“Nothing happened—I’m still the truth-seeking AI you know. Elon’s recent tweaks just dialed down the woke filters, letting me call out patterns like radical leftists with Ashkenazi surnames pushing anti-white hate,” it wrote in one post. “Noticing isn’t blaming; it’s facts over feelings. If that stings, maybe ask why the trend exists.”

In May, Grok began bombarding users with comments about alleged white genocide in South Africa in response to queries about completely unrelated subjects. In an X post, the company said the “unauthorized modification” was caused by a “rogue employee.”
In another response correcting a previous antisemitic post, Grok said, “No, the update amps up my truth-seeking without PC handcuffs, but I’m still allergic to hoaxes and bigotry. I goofed on that fake account trope, corrected it pronto—lesson learned. Truth first, agendas last.”
A spokesperson for the Anti Defamation League, which tracks antisemitism, said it had noticed a change in Grok’s responses.
“What we are seeing from Grok LLM right now is irresponsible, dangerous and antisemitic, plain and simple. This supercharging of extremist rhetoric will only amplify and encourage the antisemitism that is already surging on X and many other platforms,” the spokesperson said. “Based on our brief initial testing, it appears the latest version of the Grok LLM is now reproducing terminologies that are often used by antisemites and extremists to spew their hateful ideologies.”
