Underwater volcano off West Coast could erupt later this year, scientists say
Experts believe an underwater volcano off the Pacific Coast may be close to erupting.
The volcano, known as Axial Seamount, is more than 4,900 feet beneath the Pacific Ocean and 300 miles off the Oregon coast. In relation to California, it is about 700 miles northwest of San Francisco.
Despite its low familiarity among the public, the submarine volcano is considered the most active in the Pacific Northwest. Scientists say the looming eruption will offer an unprecedented glimpse into Earth-shaping processes that are usually hidden deep beneath the waves, the Los Angeles Times reports.
'Over two-thirds of the Earth's surface was formed by volcanic eruptions at these mid-ocean ridges,' Maya Tolstoy, a marine geophysicist and dean of the University of Washington's College of the Environment, said in a university blog post. 'Axial Seamount is a direct result of these fundamental processes that continue to shape our planet today.'
Thankfully, experts say the potential eruption poses no danger to residents.
'Axial Seamount is much too deep and far from shore for people on land to even notice when it erupts. An eruption at Axial Seamount also has nothing to do with seismic activity on land, so Pacific Northwesterners don't need to worry about this event triggering a major earthquake or tsunami,' the blog post stated.
The volcano has erupted three times in recent years: in 1998, 2011, and 2015.
The data collected from the volcano will also help scientists improve eruption forecasting for Axial Seamount and other underwater volcanoes worldwide. Instruments installed after the 2015 eruption have enabled researchers to track the volcano's behavior.

Officials unleash surprising new weapon in fight against deadly mosquitoes in US: 'There's now evidence that it can be incorporated'
Officials in Southern California have come up with a plan to control an invasive mosquito species and the diseases they spread, the Los Angeles Times reported. Scientists at local vector districts – agencies responsible for controlling disease-carrying species – applied a technique that's been used on invasive insects since the 1950s. In 2023, one vector district released thousands of sterile male Aedes aegypti mosquitoes across select neighborhoods to study the effects, according to the LA Times. The results were clear. Populations of the species diminished by 33% in one year. The Aedes aegypti, also known as the yellow fever mosquito, is believed to have originated in sub-Saharan Africa. These bugs can only fly about 150 to 200 yards, but manage to travel internationally on freight ships and other methods of trade. They're considered invasive to other regions because they transmit diseases like yellow fever, dengue, and the Zika virus. Aedes aegypti are distributed primarily across tropical and subtropical areas throughout the world. But the black-and-white striped mosquitoes have now invaded the southern United States and, because of the planet's overheating, are moving to the north and west. Right now, the mosquitoes are present in more than a third of all counties in California. The idea behind the mission is simple. Male mosquitoes don't bite, and therefore can't spread disease to humans. Females are the primary culprits there. When the sterile males are released, the mosquitoes can still mate, but the females lay unfertilized eggs that don't hatch, decreasing the population size. Vector district officials found that releasing sterile male mosquitoes into the environment was incredibly effective. Last year, a local vector control agency for part of Los Angeles County began releasing 1,000 sterile males bi-weekly, bumping the numbers to 3,000 during peak season from August to November. "Many medium to smaller districts are now interested to use our approach," Solomon Birhanie, scientific director for West Valley Vector Control, told the LA Times. "Because there's now evidence that it can be incorporated into abatement programs without the need for hiring highly skilled personnel or demanding a larger amount of budget." Should we be actively working to kill invasive species? Absolutely It depends on the species I don't know No — leave nature alone Click your choice to see results and speak your mind.

When is the next full moon and does it really affect your health?
The next full moon – known as the Strawberry Moon – will appear on 10 June, peaking the following morning. It's not named for its colour, but because it marks the start of wild strawberry season. Some people say the full moon messes with their sleep, mood or energy. And it's not just superstition – scientists are now looking into whether lunar phases can influence things like sleep, hormones, heart health and mental wellbeing. So, is there anything in it? Here's what we know – and how to feel your best when the moon rolls around. Despite the name, the Strawberry Moon doesn't actually turn pink. The nickname comes from Native American and European traditions that tied full moons to seasonal events – in this case, the strawberry harvest. You might also hear it called the Rose Moon, Honey Moon or Mead Moon, depending on where in the world you are. This year's Strawberry Moon will be particularly striking. It's the lowest-hanging full moon of 2025 in the Northern Hemisphere, which means it will look bigger and more golden as it rises at dusk. No telescope needed – just head outside and look up. The idea that the moon impacts our health has been around for centuries. While not all of it is backed by stats (and results are often mixed), scientists are starting to dig deeper into potential connections. Here's what some of the research says: A 2013 study from the University of Basel found people took longer to fall asleep, got 30% less deep sleep, and slept about 20 minutes less during a full moon, even in controlled rooms without light or clocks. More recently, researchers at the University of Washington found a similar pattern: people went to bed later and slept less in the days leading up to a full moon, no matter where they lived or whether they had electric lighting. It means since moonlight and bedtime habits were ruled out, something else might be at play, in this case, maybe our body's own rhythm responding to the lunar cycle. The average menstrual cycle lasts around 28 to 30 days – similar to the lunar cycle – so it's no surprise the two have long been linked. In fact, the word 'menstruation' shares roots with the Greek word for moon (mene) and the Latin for month (mensis). A small 1980 study did find that some women were more likely to start their periods around the new moon. But a large-scale analysis from 2017 by period-tracking app Clue, covering more than 7.5 million cycles, found no consistent link between period start dates and moon phases. Studies on the moon's impact on heart health have been mixed. A 2021 Japanese study found no link between moon phases and out-of-hospital cardiac arrests. However, a small 2013 study reported that blood pressure readings were slightly lower during full and new moons – suggesting a subtle effect on circulation. The idea that the moon affects our mood goes way back. The word 'luna' (Latin for moon) was even linked to emotional shifts in ancient times. Modern research, though, doesn't show a clear link. A 2017 study in psychiatry reported no significant rise in mental health issues during different moon phases. That said, research suggests people with conditions like bipolar disorder may be more sensitive to sleep disruptions, which, as we've seen, can happen around the full moon. So if you have mood changes, it's less likely due to the moon and could be more about the knock-on effects of poorer rest. Even if you're not usually moon-sensitive, there's no harm in building a few easy habits around the full moon, especially if it helps you feel more balanced and better rested. Wind down early. Try switching off a bit sooner in the evenings before the full moon. Even 15 minutes can help signal to your brain it's time to relax. Block out the glow. Blackout curtains or an eye mask can support melatonin production, the hormone that helps you sleep. Move your body. A little gentle exercise during the day (like walking or yoga) can help regulate sleep and release stress. Skip the caffeine – or cut back after 2pm. It can sneakily mess with your sleep, even if you feel fine. Track patterns: If you notices changes, jot down how you feel during different moon phases. You might be more in sync than you realise.

Can AI Come Up With Better Ideas Than People? Sort Of, Science Says.
This story appears in the May 2025 issue of Entrepreneur. Subscribe » Need a great idea? Ask the masses. "Crowdsourcing" has become a popular way for companies to gather insights — because when you bring together people with diverse knowledge and approaches, you can find unexpected genius. But crowdsourcing is time-consuming and expensive. Could generative AI help? Researchers at Harvard Business School and the University of Washington's Foster School of Business decided to find out. Related: Why Every Company Should Be Thinking About Artificial Intelligence The research The study set up a crowdsourcing challenge. The question was: "Who has ideas for how companies can implement the circular economy into their business to make them more climate-friendly?" First, the researchers invited real people to submit their suggestions and ended up with 125 ideas. Next, the researchers prompted ChatGPT's GPT-4 with the same question and slight variations, which produced 730 solutions. All the ideas were reviewed by 300 human judges, who evaluated them based on novelty, value, and quality. The results The human-generated solutions were more novel, but in many ways, the AI-prompted concepts were better — higher quality, more strategically viable, with greater financial and environmental value. As for the economics of the project, they were stark: To produce those 125 human submissions required a combined 2,520 hours of work — and $2,555 to cover expenses. But to get the 730 solutions from AI, it took just 5.5 hours and cost only $27.01. Related: How Crowdsourcing Is Shaping the Future of Everything What we've learned Generative AI is great at generating ideas — but it can't do it all on its own. To succeed, you need to give the tool very clear, thoughtful prompts, says study investigator Léonard Boussioux, an assistant professor at the University of Washington's Foster School of Business who's also affiliated with Harvard Business School. In their experiment, he and his colleagues tried two distinct strategies. In the first, along with the challenge question, they asked GPT-4 to assume 100 different personas (executive, manager, entrepreneur) to replicate the variety of humans who might reply to a crowdsource request. In the second approach, they prompted the AI with the same question and got a first answer — and then followed it up by asking, "Make sure to tackle a different problem than the previous ones and propose a different solution." They repeated this 100 times, with a different persona each time, as if it were one person pushed to give various perspectives. The result: The second approach led to more novel, viable, and quality ideas. How to use this Let's say your company is considering a pivot. "The quality of your questioning and critical thinking is what matters most," Boussioux says. "But AI can help you find good starting questions. Describe your company, the stakeholders, your goals. Include as much data as you can — a blog post about what you do, financial spreadsheets, a white paper. Then ask something like, 'I'm looking maybe to pivot. Can you suggest a direction to investigate?'" This can get you going. Try iterative prompting, but don't do it 100 times like the study did. "We found that if you keep asking for too long, the final ideas are potentially more creative, but they're also not as feasible or valuable," Boussioux says. The sweet spot? Two to four times.
