Artificial intelligence, touted for its potential to transform medicine, led to some doctors losing skills after just a few months in a new study.

AI helped health professionals to better detect pre-cancerous growths in the colon, but when the assistance was removed, their ability to find tumors dropped by about 20% compared with rates before the tool was ever introduced, according to findings published Wednesday.

Health care systems around the world are embracing AI with a view to boosting patient outcomes and productivity. Just this year, the UK government announced £11 million ($14.8 million) in funding for a new trial to test how AI can help catch breast cancer earlier.

The AI in the study probably prompted doctors to become over-reliant on its recommendations, “leading to clinicians becoming less motivated, less focused, and less responsible when making cognitive decisions without AI assistance,” the scientists said in the paper.

They surveyed four endoscopy centers in Poland and compared detection success rates three months before AI implementation and three months after. Some colonoscopies were performed with AI and some without, at random. The results were published in The Lancet Gastroenterology and Hepatology journal.

Yuichi Mori, a researcher at the University of Oslo and one of the scientists involved, predicted that the effects of de-skilling will “probably be higher” as AI becomes more powerful.

What’s more, the 19 doctors in the study were highly experienced, having performed more than 2,000 colonoscopies each. The effect on trainees or novices might be starker, said Omer Ahmad, a consultant gastroenterologist at University College Hospital London.

“Although AI continues to offer great promise to enhance clinical outcomes, we must also safeguard against the quiet erosion of fundamental skills required for high-quality endoscopy,” Ahmad, who wasn’t involved in the research, wrote a comment alongside the article.

A study conducted by MIT this year raised similar concerns after finding that using OpenAI’s ChatGPT to write essays led to less brain engagement and cognitive activity.

TREMONTON, Utah (AP) — Two police officers were shot and killed in a northern Utah city and a man was taken into custody, authorities said Monday.

The officers were responding to a domestic disturbance call Sunday in a neighborhood in Tremonton. A sheriff’s deputy and a police dog who also responded were wounded and were hospitalized in fair condition, police said.

After the officers were shot, bystanders persuaded the man to put down his weapon, police said. SWAT teams responded to clear the home and verify that there was no further threat, police said.

“Upon arrival, they immediately began taking fire,” Police Detective Crystal Beck of neighboring Brigham City told reporters earlier. “They requested additional units. And then stopped answering their radio.”

The man was arrested on charges of aggravated murder, police said in a news release. His name was not immediately released.

Tremonton, which has about 10,000 people, is about 75 miles north of Salt Lake City.

Wall Street ticked modestly lower early Monday ahead of U.S. President Donald Trump’s meeting later Monday with Ukrainian President Volodymyr Zelenskyy and other European leaders.

Futures for the S&P 500, Dow Jones Industrial Average and Nasdaq were all 0.1% lower before the bell.

Markets showed scant reaction to Trump’s inconclusive summit meeting with Russian President Vladimir Putin on Friday. Investors are also watching for cues from an annual meeting in Jackson Hole, Wyoming, of top central bankers later this week.

In premarket trading, Soho House jumped 16% after the global membership-based club said it was being taken private by hotel operator MCR. Executive Chairman Ron Burkle and other big shareholders will retain their equity interests and control of the business.

Dayforce, a human resources software company, climbed more than 28% before the bell on media reports that it is being acquired by Chicago-based private equity firm Thoma Bravo. Bloomberg reported that Thoma Bravo was offering $9 billion, including debt, to take Dayforce private.

Some of the biggest U.S. retailers will report their latest financial results throughout the week, including Home Depot, Target and Walmart.

Trump’s meeting with Zelenskyy will include other European leaders who were not included in the president’s talks in Anchorage, Alaska, with Putin. The European allies are seeking to present a united front in safeguarding Ukraine and the continent from any widening aggression from Moscow.

An annual meeting in Jackson Hole, Wyoming, of top central bankers later this week will be watched closely for hints about possible interest rate cuts from Federal Reserve chair Jerome Powell. He is due to speak Friday at the conference.

“While the official theme is labor markets, investors will scrutinize any hint of September policy direction, especially after last week’s mixed inflation data,” Ipek Ozkardeskaya of Swissquote said in a commentary, adding that “any progress on Ukraine peace talks could push global equities higher still.”

Expectations have been building that the Fed will cut interest rates at its next meeting in September, though mixed reports on the U.S. economy have undercut those bets somewhat.

At midday in Europe, Germany’s DAX lost 0.3%, while the CAC 40 in Paris dropped 0.7%. Britain’s FTSE 100 was flat.

In Asia, Japan’s Nikkei 225 picked up 0.8%, while the Hang Seng in Hong Kong gave up early gains, losing 0.4%.

The Shanghai Composite index jumped 1%. It’s trading near it’s highest level in a decade.

Australia’s S&P/ASX 200 picked up 0.2%.

The Kospi in South Korea declined 1.5% on heavy selling of semiconductor makers like Samsung Electronics, whose shares fell 2.2%. SK Hynix lost 3.3% as investors fretted over the possibility of more U.S. tariffs on computer chips.

MIAMI (AP) — A stronger and bigger Hurricane Erin pelted parts of the Caribbean and was forecast to create dangerous surf and rip currents along the U.S. East Coast this week.

It reintensified to a Category 4 storm with 130 mph maximum sustained winds early Monday and moved closer to the Southeast Bahamas, according to the U.S. National Hurricane Center in Miami.

Around 5 a.m. Monday, Erin was about 105 miles north-northeast of Grand Turk Island and about 915 miles south-southeast of Cape Hatteras, North Carolina. The storm was moving northwest at 13 mph.

The Bahamas government issued a Tropical Storm Watch for the central Bahamas, while a Tropical Storm Warning remained in effect for the Turks and Caicos Islands and southeast Bahamas, the hurricane center reported.

Additional strengthening was forecast for Monday followed by gradual weakening, but Erin was expected to remain a large, major hurricane into midweek.

Hurricane-force winds extended up to 60 miles from the center and tropical-storm-force winds extend outward up to 230 miles. The area of strong winds is expected to grow more over the next few days. At that size, Erin will impact coastal areas even though it isn’t forecast to make a direct landfall.

Dare County, North Carolina, declared an emergency and ordered an evacuation beginning Monday of Hatteras Island on the Outer Banks, the thin stretch of low-lying barrier islands that juts far into the Atlantic. Several days of heavy surf and high winds and waves could wash out parts of N.C. Highway 12 running along the barrier islands, the National Weather Service said.

Erin, the year’s first Atlantic hurricane, reached an exceedingly dangerous Category 5 status Saturday with 160 mph (260 kph) winds before weakening.

“You’re dealing with a major hurricane. The intensity is fluctuating. It’s a dangerous hurricane in any event,” Richard Pasch of the National Hurricane Center said.

Erin’s outer bands pelted parts of Puerto Rico and the Virgin Islands with heavy rains and tropical-storm winds during the day Sunday.

That knocked out power to about 147,000 customers, according to Luma Energy, a private company that oversees the transmission and distribution of power on the island. More than 20 flights were canceled due to the weather. The Coast Guard allowed all ports in Puerto Rico and the U.S. Virgin Islands to reopen Sunday as winds and rains decreased.

Rough ocean conditions were forecast for parts of the Virgin Islands, Puerto Rico, Hispaniola and the Turks and Caicos. Life-threatening surf and rip currents were forecast into midweek for the Bahamas, Bermuda, the U.S. East Coast and Canada’s Atlantic coast as Erin turns north and then northeast.

Scientists have linked the rapid intensification of hurricanes in the Atlantic to climate change. Global warming is causing the atmosphere to hold more water vapor and is spiking ocean temperatures, and warmer waters give hurricanes fuel to unleash more rain and strengthen more quickly.
