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.

Following court decisions that blocked some NIH grant cancellations or rendered them “void” and “illegal,” NIH official Michelle Bulls in late June told staffers to stop terminating grants. However, NCI workers told KFF Health News they continue to review grants flagged by NIH to assess whether they align with Trump administration priorities. Courts have ordered NIH to reinstate some terminated grants, but not all of them.

At NCI and across NIH, staffers remain anxious.

The White House wants Congress to slash the cancer institute’s budget by nearly 40%, to $4.53 billion, as part of a larger proposal to sharply reduce NIH’s fiscal 2026 coffers.

Bhattacharya has said he wants NIH to fund more big, breakthrough research. Major cuts could have the opposite effect, Knudsen said. When NCI funding shrinks, “it’s the safe science that tends to get funded, not the science that is game changing and has the potential to be transformative for cures.”

Usually the president’s budget is dead on arrival in Congress, and members of both parties have expressed doubt about Trump’s 2026 proposal. But agency workers, outside scientists, and patients fear this one may stick, with devastating impact.

It would force NCI to suspend all new grants or cut existing grants so severely that the gaps will close many labs, said Varmus, who ran NCI from 2010 to 2015. Add that to the impact on NCI’s contracts, clinical trials, internal research, and salaries, he said, and “you can reliably say that NCI will be unable to keep up in any way with the promise of science that’s currently underway.”

The NCI laboratory chief, who has worked at the institute for decades, put it this way: “If the 40% budget cut passes in Congress, it will destroy clinical research at NCI.”

High costs are still a big barrier to prospective customers, said Alan Gibson, principal at Maine-based builder GO Logic, where a shell for an ultra-efficient, two-story, 1,400 square foot home with three bedrooms can cost around $600,000.

Homeowners also need to factor in additional costs, like buying and developing a suitable plot of land, and in some cases, getting access to water, electricity and septic, Gibson added.

The way to bring down costs, Gibson believes, is more panelized, multi-family housing.

“It can be done so much more efficiently,” Gibson said, “and there’s a lot more repetition” for the developer, making the process faster and less expensive than custom multi-family builds.
Goodson, the homeowner in Maine, was able to save big money with his engineering background and penchant for DIY. He installed a rooftop solar system and electrical improvements himself, saving hundreds of thousands of dollars in the process. He wound up spending around $500,000 in all, which he estimates was $200,000 less than he otherwise would have.
“It’s a big number to swallow, I’m not making light of that at all, but it’s not that far out of what’s reasonable,” Goodson told CNN. It’s also not considering the long-term savings he will experience with no utility bills.

He was also able to take advantage of federal tax credits that reduced the cost of his rooftop solar, which saved him more than $10,000 on his panels. Those tax credits are now endangered with House Republicans’ tax bill.

“That was huge,” he said. “It’s fairly unfortunate they’re looking at doing away with it.”

The CO2 that is extracted from the water is run through a purification process that uses activated carbon in the form of charred coconut husks, and is then ready to be stored.
трипскан вход
In a scaled up system, it would be fed into geological CO2 storage. Before the water is released, its acidity is restored to normal levels, making it ready to absorb more carbon dioxide from the air.

“This discharged water that now has very low carbon concentrations needs to refill it, so it’s just trying to suck CO2 from anywhere, and it sucks it from the atmosphere,” says Halloran. “A simple analogy is that we’re squeezing out a sponge and putting it back.”

While more tests are needed to understand the full potential of the technology, Halloran admits that it doesn’t “blow direct air capture out the water in terms of the energy costs,” and there are other challenges such as having to remove impurities from the water before releasing it, as well as the potential impact on ecosystems. But, he adds, all carbon capture technologies incur high costs in building plants and infrastructure, and using seawater has one clear advantage: It has a much higher concentration of carbon than air does, “so you should be able to really reduce the capital costs involved in building the plants.”

Mitigating impacts
One major concern with any system that captures carbon from seawater is the impact of the discharged water on marine ecosystems. Guy Hooper, a PhD researcher at the University of Exeter, who’s working on this issue at the SeaCURE site, says that low-carbon seawater is released in such small quantities that it is unlikely to have any effect on the marine environment, because it dilutes extremely quickly.

However, that doesn’t mean that SeaCURE is automatically safe. “To understand how a scaled-up version of SeaCURE might affect the marine environment, we have been conducting experiments to measure how marine organisms respond to low-carbon seawater,” he adds. “Initial results suggest that some marine organisms, such as plankton and mussels, may be affected when exposed to low-carbon seawater.”

To mitigate potential impacts, the seawater can be “pre-diluted” before releasing it into the marine environment, but Hooper warns that a SeaCURE system should not be deployed near any sensitive marine habitats.

There is rising interest in carbon capture from seawater — also known as Direct Ocean Capture or DOC — and several startups are operating in the field. Among them is Captura, a spin off from the California Institute of Technology that is working on a pilot project in Hawaii, and Amsterdam-based Brineworks, which says that its method is more cost-effective than air carbon capture.
According to Stuart Haszeldine, a professor of Carbon Capture and Storage at the University of Edinburgh, who’s not involved with SeaCURE, although the initiative appears to be more energy efficient than current air capture pilot tests, a full-scale system will require a supply of renewable energy and permanent storage of CO2 by compressing it to become a liquid and then injecting it into porous rocks deep underground.

He says the next challenge is for SeaCURE to scale up and “to operate for longer to prove it can capture millions of tons of CO2 each year.”

But he believes there is huge potential in recapturing carbon from ocean water. “Total carbon in seawater is about 50 times that in the atmosphere, and carbon can be resident in seawater for tens of thousands of years, causing acidification which damages the plankton and coral reef ecosystems. Removing carbon from the ocean is a giant task, but essential if the consequences of climate change are to be controlled,” he says.

Today was supposed to be the day that President Donald Trump’s so-called “reciprocal” tariffs on dozens of countries kicked in after a three-month delay, absent trade deals. But their introduction has been postponed, again.

The new, August 1 deadline prolongs uncertainty for businesses but also gives America’s trading partners more time to strike trade deals with the United States, avoiding the hefty levies.

Mainstream economists would probably cheer that outcome. Most have long disliked tariffs and can point to research showing they harm the countries that impose them, including the workers and consumers in those economies. And although they also recognize the problems free trade can create, high tariffs are rarely seen as the solution.

Trump’s tariffs so far have not meaningfully boosted US inflation, slowed the economy or hurt jobs growth. Inflation is “the dog that didn’t bark,” Treasury Secretary Scott Bessent likes to say. But economists argue inflation and jobs will have a delayed reaction to tariffs that could start to get ugly toward the end of the year, and that the current calm before the impending storm has provided the administration with a false sense of security.

“The positives (of free trade) outweigh the negatives, even in rich countries,” Antonio Fatas, an economics professor at business school INSEAD, told CNN. “I think in the US, the country has benefited from being open, Europe has benefited from being open.”

Consumers lose out
Tariffs are taxes on imports and their most direct typical effect is to drive up costs for producers and prices for consumers.

Around half of all US imports are purchases of so-called intermediate products, needed to make finished American goods, according to data from the Organisation for Economic Co-operation and Development.

“If you look at a Boeing aircraft, or an automobile manufactured in the US or Canada… it’s really internationally sourced,” Doug Irwin, an economics professor at Dartmouth College, said on the EconTalk podcast in May. And when American businesses have to pay more for imported components, it raises their costs, he added.

Likewise, tariffs raise the cost of finished foreign goods for their American importers.

“Then they have to pass that on to consumers in most instances, because they don’t have deep pockets where they can just absorb a 10 or 20 or 30% tariff,” Irwin said.

The bow of a US Navy cruiser damaged in a World War II battle in the Pacific has shone new light on one of the most remarkable stories in the service’s history.

More than 80 years ago, the crew of the USS New Orleans, having been hit by a Japanese torpedo and losing scores of sailors, performed hasty repairs with coconut logs, before a 1,800-mile voyage across the Pacific in reverse.

The front of the ship, or the bow, had sunk to the sea floor. But over the weekend, the Nautilus Live expedition from the Ocean Exploration Trust located it in 675 meters (2,214 feet) of water in Iron Bottom Sound in the Solomon Islands.

Using remotely operated underwater vehicles, scientists and historians observed “details in the ship’s structure, painting, and anchor to positively identify the wreckage as New Orleans,” the expedition’s website said.

On November 30, 1942, New Orleans was struck on its portside bow during the Battle of Tassafaronga, off Guadalcanal island, according to an official Navy report of the incident.
https://kra34g.cc

The torpedo’s explosion ignited ammunition in the New Orleans’ forward ammunition magazine, severing the first 20% of the 588-foot warship and killing more than 180 of its 900 crew members, records state.

The crew worked to close off bulkheads to prevent flooding in the rest of the ship, and it limped into the harbor on the island of Tulagi, where sailors went into the jungle to get repair supplies.

“Camouflaging their ship from air attack, the crew jury-rigged a bow of coconut logs,” a US Navy account states.
With that makeshift bow, the ship steamed – in reverse – some 1,800 miles across the Pacific to Australia for sturdier repairs, according to an account from the National World War II Museum in Louisiana.

Retired US Navy Capt. Carl Schuster described to CNN the remarkable skill involved in sailing a warship backwards for that extended distance.

“‘Difficult’ does not adequately describe the challenge,” Schuster said.

While a ship’s bow is designed to cut through waves, the stern is not, meaning wave action lifts and drops the stern with each trough, he said.

When the stern rises, rudders lose bite in the water, making steering more difficult, Schuster said.

And losing the front portion of the ship changes the ship’s center of maneuverability, or its “pivot point,” he said.

“That affects how the ship responds to sea and wind effects and changes the ship’s response to rudder and propellor actions,” he said.

The New Orleans’ officers would have had to learn – on the go – a whole new set of actions and commands to keep it stable and moving in the right direction, he said.

The ingenuity and adaptiveness that saved the New Orleans at the Battle of Tassafaronga enabled it to be a force later in the war.

The latest Barbie slays in a chic blue polka-dot crop top, ruffled miniskirt, chunky heels and an insulin pump. She is the brand’s first doll with type 1 diabetes.
трипскан сайт
Dollmaker Mattel worked with Breakthrough T1D, formerly known the Juvenile Diabetes Research Foundation, to design the doll, which aims to represent the roughly 304,000 kids and teens living with type 1 diabetes in the United States.
https://tripscan.biz
tripskan
The doll launched Tuesday at the Breakthrough T1D Children’s Congress, a three-day event in Washington that brings in kids and teens living with the condition to meet with lawmakers. This year, they’re asking Congress to renew funding for the Special Diabetes Program, which was first allocated by Congress in 1997. The program’s current funding ends after September.

The advocacy efforts have taken on new urgency this year. With so many deep cuts to federally funded projects in recent months, Breakthrough T1D said it’s anxiously watching to see if this funding will be reupped.

Type 1 diabetes is an autoimmune disease, meaning the body mistakenly attacks its own organs and tissues. In this case, rough antibodies go after cells in the pancreas that make insulin, an essential hormone that helps the body turn food into energy. As a result, the body doesn’t make enough of its own insulin, so people have to take insulin by injection or though a pump to survive.

Type 1 diabetes is typically diagnosed in childhood but can be diagnosed in anyone at any age. It differs from type 2 diabetes, in which people are still able to make insulin but their cells stop responding to it.

In addition to the insulin pump that attaches to the new Barbie’s waist, the chestnut-haired beauty has a continuous glucose monitor on her arm – a button held on by a strip of heart-shaped Barbie-pink tape. Her cell phone displays an app that shows her glucose readings. She also has a light blue purse to hold her supplies and snacks to help her manage her blood sugar throughout the day. It matches her shoes, of course.

“AI expends a lot of energy being polite, especially if the user is polite, saying ‘please’ and ‘thank you,’”
tripskan
Dauner explained. “But this just makes their responses even longer, expending more energy to generate each word.”

For this reason, Dauner suggests users be more straightforward when communicating with AI models. Specify the length of the answer you want and limit it to one or two sentences, or say you don’t need an explanation at all.

Most important, Dauner’s study highlights that not all AI models are created equally, said Sasha Luccioni, the climate lead at AI company Hugging Face, in an email. Users looking to reduce their carbon footprint can be more intentional about which model they chose for which task.

“Task-specific models are often much smaller and more efficient, and just as good at any context-specific task,” Luccioni explained.
https://tripscan.biz
tripscan top
If you are a software engineer who solves complex coding problems every day, an AI model suited for coding may be necessary. But for the average high school student who wants help with homework, relying on powerful AI tools is like using a nuclear-powered digital calculator.

Even within the same AI company, different model offerings can vary in their reasoning power, so research what capabilities best suit your needs, Dauner said.

When possible, Luccioni recommends going back to basic sources — online encyclopedias and phone calculators — to accomplish simple tasks.

Why it’s hard to measure AI’s environmental impact
Putting a number on the environmental impact of AI has proved challenging.

The study noted that energy consumption can vary based on the user’s proximity to local energy grids and the hardware used to run AI models.
That’s partly why the researchers chose to represent carbon emissions within a range, Dauner said.

Furthermore, many AI companies don’t share information about their energy consumption — or details like server size or optimization techniques that could help researchers estimate energy consumption, said Shaolei Ren, an associate professor of electrical and computer engineering at the University of California, Riverside who studies AI’s water consumption.

“You can’t really say AI consumes this much energy or water on average — that’s just not meaningful. We need to look at each individual model and then (examine what it uses) for each task,” Ren said.

One way AI companies could be more transparent is by disclosing the amount of carbon emissions associated with each prompt, Dauner suggested.

Guatemala has pledged a 40% increase in deportation flights carrying Guatemalans and migrants of other nationalities from the United States, President Bernardo Arevalo announced Wednesday during a press conference with US Secretary of State Marco Rubio.

Guatemala has also agreed to create a task force for border control and protection along the country’s eastern borders. The force, composed of members of the National Police and army, will be tasked with fighting “all forms of transnational crime,” Arevalo said.

Foreign nationals who arrive in Guatemala through deportation flights will be repatriated to their home countries, Arevalo said, adding that the US and Guatemala would continue to have talks on how the process would work and how the US would cooperate.

Arevalo also said that Rubio has voiced his support for developing infrastructure projects in the Central American nation. He added that his government would send a delegation to Washington in the coming weeks to negotiate deals for economic investments in Guatemala – which he said would incentivize Guatemalans to stay in their home country and not migrate to the US.

Arevalo said Guatemala has not had any discussions about receiving criminals from the US as El Salvador’s president has offered. He also insisted his country has not reached a “safe third country” agreement with the United States, which would require migrants who pass through Guatemala to apply for asylum there rather than continuing to the US.
