UK project trials carbon capture at sea to help tackle climate change
[url=https://tripscan.biz]tripscan войти[/url]
The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.

The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.

Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.

In the UK, where the government in 2023 announced up to ?20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.

“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.

“But it also means it’s very straightforward to take that carbon out of the water.”

Pilot plant
SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.

“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.

The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.

Study reveals how much energy AI uses to answer your questions
[url=https://tripscan.biz]трипскан вход[/url]
Whether it’s answering work emails or drafting wedding vows, generative artificial intelligence tools have become a trusty copilot in many people’s lives. But a growing body of research shows that for every problem AI solves, hidden environmental costs are racking up.

Each word in an AI prompt is broken down into clusters of numbers called “token IDs” and sent to massive data centers — some larger than football fields — powered by coal or natural gas plants. There, stacks of large computers generate responses through dozens of rapid calculations.

The whole process can take up to 10 times more energy to complete than a regular Google search, according to a frequently cited estimation by the Electric Power Research Institute.

So, for each prompt you give AI, what’s the damage? To find out, researchers in Germany tested 14 large language model (LLM) AI systems by asking them both free-response and multiple-choice questions. Complex questions produced up to six times more carbon dioxide emissions than questions with concise answers.

In addition, “smarter” LLMs with more reasoning abilities produced up to 50 times more carbon emissions than simpler systems to answer the same question, the study reported.

“This shows us the tradeoff between energy consumption and the accuracy of model performance,” said Maximilian Dauner, a doctoral student at Hochschule Munchen University of Applied Sciences and first author of the Frontiers in Communication study published Wednesday.

Typically, these smarter, more energy intensive LLMs have tens of billions more parameters — the biases used for processing token IDs — than smaller, more concise models.

“You can think of it like a neural network in the brain. The more neuron connections, the more thinking you can do to answer a question,” Dauner said.
What you can do to reduce your carbon footprint
Complex questions require more energy in part because of the lengthy explanations many AI models are trained to provide, Dauner said. If you ask an AI chatbot to solve an algebra question for you, it may take you through the steps it took to find the answer, he said.

Beirut, Lebanon
CNN
—
A deadly Israeli airstrike on Hezbollah’s stronghold in southern Beirut on Friday has left over a dozen people dead, including a high-ranking Hezbollah commander, sharply escalating the conflict between the two sides and raising fears of all-out war.
[url=][/url]
Senior Hezbollah commander Ibrahim Aqil, part of Hezbollah’s elite Radwan Force, was assassinated along with “about 10” other commanders, Israel Defense Forces (IDF) spokesperson Daniel Hagari said, accusing them of planning to raid and occupy communities in Galilee in northern Israel.

Hezbollah confirmed Aqil’s death on Friday, saying he was killed “following a treacherous Israeli assassination operation on 09/20/2024 in the southern suburbs of Beirut.”

According to Hagari, the targeted commanders were “underground underneath a residential building in the heart of the Dahiyeh neighborhood, using civilians as a human shield” at the time of the attack.

Lebanon’s health ministry said at least 14 people were killed and 66 others injured in the airstrike, which leveled a multistory building in a densely populated neighborhood.

Aqil had a $7 million bounty on his head from the United States for his suspected involvement in the 1983 strike on the US Embassy in Beirut, which killed 63 people, as well as the bombing of the Beirut Marine barracks, which killed 241 US personnel later that year.

A CNN team on the ground in Beirut saw a frantic effort to rescue people from underneath the rubble and rush the wounded to hospital. Witnesses said nearby buildings shook for nearly half an hour after the strike, which the IDF said it had carried out at around 4 p.m. local time.


A week of surprise attacks
Friday’s strike marked the fourth consecutive day of surprise attacks on Beirut and other sites across the country, even as Israeli forces continued deadly strikes and operations in Gaza and the occupied West Bank.

The first major attack against Hezbollah this week came Tuesday afternoon when pagers belonging to the militant groups’ members exploded near-simultaneously. The pagers had been used by Hezbollah to communicate after the group’s leader, Hassan Nasrallah, encouraged members to switch to low-tech devices to prevent more of them from being assassinated.

Almost exactly 24 hours later, Lebanon was rocked by a second wave of explosions, after Hezbollah walkie-talkies detonated in Beirut and the south of the country on Wednesday.

At least 37 people were killed, including some children, and more than 3,000 were injured in the twin attacks.

In a United Nations Security Council meeting on Friday, UN human rights chief Volker Turk on Friday warned that the detonation of communication devices could violate international human rights law.

Lebanese Foreign Minister Abdallah Bou Habib and Israeli Ambassador to the UN Danny Danon clashed at the heated meeting, with Bou Habib calling on the council to condemn Israel’s actions and Danon slamming the Lebanese envoy for not mentioning Hezbollah.

Ukrainian President Volodymyr Zelensky’s visit to the White House on Thursday could be his final chance to convince a receptive American president of his country’s war aims.
[url=https://megaweb-18at.com]megaweb4.at[/url]
The precise details of the “victory plan” Zelensky plans to present in separate meetings to President Joe Biden and Vice President Kamala Harris are unknown, having been closely held until they are presented to the American leaders.

But according to people briefed on its broad contours, the plan reflects the Ukrainian leader’s urgent appeals for more immediate help countering Russia’s invasion. Zelensky is also poised to push for long-term security guarantees that could withstand changes in American leadership ahead of what is widely expected to be a close presidential election between Harris and former President Donald Trump.

The plan, people familiar with it said, acts as Zelensky’s response to growing war weariness even among his staunchest of western allies. It will make the case that Ukraine can still win — and does not need to cede Russian-seized territory for the fighting to end — if enough assistance is rushed in.

That includes again asking permission to fire Western provided long-range weapons deeper into Russian territory, a line Biden once was loathe to cross but which he’s recently appeared more open to as he has come under growing pressure to relent.

Even if Biden decides to allow the long-range fires, it’s unclear whether the change in policy would be announced publicly.

Biden is usually apt to take his time making decisions about providing Ukraine new capabilities. But with November’s election potentially portending a major change in American approach to the war if Trump were to win, Ukrainian officials — and many American ones — believe there is little time to waste.

Trump has claimed he will be able to “settle” the war upon taking office and has suggested he’ll end US support for Kyiv’s war effort.

“Those cities are gone, they’re gone, and we continue to give billions of dollars to a man who refused to make a deal, Zelensky. There was no deal that he could have made that wouldn’t have been better than the situation you have right now. You have a country that has been obliterated, not possible to be rebuilt,” Trump said during a campaign speech in Mint Hill, North Carolina, on Wednesday.

Comments like those have lent new weight to Thursday’s Oval Office talks, according to American and European officials, who have described an imperative to surge assistance to Ukraine while Biden is still in office.

As part of Zelensky’s visit, the US is expected to announce a major new security package, thought it will likely delay the shipping of the equipment due to inventory shortages, CNN previously reported according to two US officials. On Wednesday, the US announced a package of $375 million.

The president previewed Zelensky’s visit to the White House a day beforehand, declaring on the margins of the United Nations General Assembly his administration was “determined to ensure that Ukraine has what it needs to prevail in fight for survival.”

“Tomorrow, I will announce a series of actions to accelerate support for Ukraine’s military – but we know Ukraine’s future victory is about more than what happens on the battlefield, it’s also about what Ukrainians do make the most of a free and independent future, which so many have sacrificed so much for,” he said.

Autism Spectrum Disorder (ASD) affects millions of individuals worldwide, posing significant challenges for families and healthcare providers alike. In recent years, the focus has shifted towards exploring innovative treatment options, one of which is stem cell therapy. This article looks into how stem cell therapy is being perceived and researched as a potential treatment for autism in the USA.

Understanding Autism and Its Challenges

Autism is a complex developmental disorder characterized by difficulties in social interaction, communication, and repetitive behaviors. The spectrum nature of autism means symptoms and their severity can vary widely. Traditional treatments often include behavioral therapy, speech therapy, and medications targeting specific symptoms. However, these interventions do not address the root causes of autism.

The Potential of Stem Cell Therapy

Stem cells are unique in their ability to develop into different types of cells. This regenerative capability has made them a focus of research for various conditions, including neurological disorders. Stem cell therapy aims to repair, regenerate, or replace damaged cells, offering a new hope for conditions that previously had limited treatment options.

Research and Developments in the USA

In the USA, several research studies and clinical trials are exploring the viability of stem cell therapy for autism. Researchers are investigating whether stem cells can reduce inflammation, repair neural connections, and improve symptoms related to autism. Although results are still preliminary, early findings are promising.

Ethical and Regulatory Considerations

The use of stem cells, especially embryonic stem cells, has raised ethical concerns and rigorous regulatory scrutiny. In the USA, the Food and Drug Administration (FDA) oversees clinical trials to ensure safety and efficacy. While some clinics offer stem cell treatments, potential patients should be cautious and ensure that these treatments comply with FDA regulations.

Success Stories and Ongoing Challenges

Some families have reported improvements http://stemcellinjectionitaly.com/ in their children's symptoms following stem cell therapy. Testimonials include enhanced communication skills, improved social interactions, and better behavior management. However, scientific validation is essential to separate anecdotal success from broader applicability.

Researchers face the challenge of understanding how stem cells interact with the brain and identifying which specific cell types can produce the most benefit. Additionally, developing standardized protocols for treatment is crucial for it to become a mainstream option.

The Future of Autism Treatment

As research progresses, stem cell therapy holds the potential to become a groundbreaking treatment for autism. In the USA, ongoing trials and studies could lead to a deeper understanding of autism and innovative therapies that address its core causes.

In conclusion, while still in the experimental phase, stem cell therapy represents a beacon of hope for many families affected by autism. Continued research, ethical considerations, and regulatory oversight are key to unlocking its full potential as a safe and effective treatment option.
