SYDNEY — Researchers in New Zealand say that artificial intelligence, or AI, can help solve problems for patients and doctors.
A new study from the University of Auckland says that an emerging area is the use of AI during operations using so-called “computer vision.”
The study, published in the journal Nature Medicine, says that artificial intelligence has the potential to identify abnormalities during operations and to unburden overloaded hospitals by enhancing the monitoring of patients to help them recover after surgery at home.
The New Zealand research details how AI “tools are rapidly maturing for medical applications.” It asserts that “medicine is entering an exciting phase of digital innovation.”
The New Zealand team is investigating computer vision, which describes a machine’s understanding of videos and images.
Dr. Chris Varghese, a doctoral researcher in the Department of Surgery at the Faculty of Medical and Health Sciences at the University of Auckland, led the AI research team.
He told VOA the technology has great potential.
“The use of AI in surgery is a really emerging field. We are seeing a lot of exciting research looking at what we call computer vision, where AI is trying to learn what surgeons see, what the surgical instruments look like, what the different organs look like, and the potential there is to identify abnormal anatomy or what the safest approach to an operation might be using virtual reality and augmented reality to plan ahead of surgeries, which could be really useful in cutting out cancers and things like that.”
Varghese said doctors in New Zealand are already using AI to help sort through patient backlogs.
“We are using automated algorithms to triage really long waiting lists,” he said. “So, getting people prioritized and into clinics ahead of time, based on need, so the right patients are seen at the right time.”
The researchers said there are limitations to the use of artificial intelligence because of concerns about data privacy and ethics.
The report concludes that “numerous apprehensions remain with regard to the integration of AI into surgical practice, with many clinicians perceiving limited scope in a field dominated by experiential” technology.
The study also says that “autonomous robotic surgeons…. is the most distant of the realizable goals of surgical AI systems.”

WASHINGTON — U.S. President Joe Biden on Tuesday unveiled a bundle of steep tariff increases on an array of Chinese imports including electric vehicles, computer chips and medical products, risking an election-year standoff with Beijing in a bid to woo voters who give his economic policies low marks.
Biden will keep tariffs put in place by his Republican predecessor Donald Trump while ratcheting up others, including a quadrupling of EV duties to over 100%, the White House said in a statement. It cited “unacceptable risks” to U.S. economic security posed by what it considers unfair Chinese practices that are flooding global markets with cheap goods.
The new measures impact $18 billion in Chinese imported goods including steel and aluminum, semiconductors, batteries, critical minerals, solar cells and cranes, the White House said. The announcement confirmed earlier Reuters reporting.
The United States imported $427 billion in goods from China in 2023 and exported $148 billion to the world’s No. 2 economy, according to the U.S. Census Bureau, a trade gap that has persisted for decades and become an ever more sensitive subject in Washington.
“China’s using the same playbook it has before to power its own growth at the expense of others by continuing to invest, despite excess Chinese capacity and flooding global markets with exports that are underpriced due to unfair practices,” White House National Economic Adviser Lael Brainard told reporters on a conference call.
U.S. Trade Representative Katherine Tai said the revised tariffs were justified because China was continuing to steal U.S. intellectual property and in some cases had become “more aggressive” in cyber intrusions targeting American technology.
She said prior “Section 301” tariffs had minimal impact on U.S. economy-wide prices and employment, but had been effective in reducing U.S. imports of Chinese goods, while increasing imports from other countries.
But Tai recommended tariff exclusions for dozens of industrial machinery import categories from China, including 19 for solar product manufacturing equipment.
Even as Biden’s steps fell in line with Trump’s premise that tougher trade measures are warranted, the Democrat took aim at his opponent in November’s election.
The White House said Trump’s 2020 trade deal with China did not increase American exports or boost American manufacturing jobs, and it said the 10% across-the-board tariffs on goods from all points of origin that Trump has proposed would frustrate U.S. allies and raise prices. Trump has floated tariffs of 60% or higher on all Chinese goods.
Administration officials said their measures are “carefully targeted,” combined with domestic investment, plotted with close allies and unlikely to worsen a bout of inflation that has already angered U.S. voters and imperiled Biden’s re-election bid. They also downplayed the risk of retaliation from Beijing.
Biden has struggled to convince voters of the efficacy of his economic policies despite a backdrop of low unemployment and above-trend economic growth. A Reuters/Ipsos poll last month showed Trump had a 7 percentage-point edge over Biden on the economy.
Analysts have warned that a trade tiff could raise costs for EVs overall, hurting Biden’s climate goals and his aim to create manufacturing jobs.
Biden has said he wants to win this era of competition with China but not to launch a trade war that could hurt the mutually dependent economies. He has worked in recent months to ease tensions in one-on-one talks with Chinese President Xi Jinping.
Both 2024 U.S. presidential candidates have sharply departed from the free-trade consensus that once reigned in Washington, a period capped by China’s joining the World Trade Organization in 2001.
China has said the tariffs are counterproductive and risk inflaming tensions. Trump’s broader imposition of tariffs during his 2017-2021 presidency kicked off a tariff war with China.
As part of the long-awaited tariff update, Biden will increase tariffs this year under Section 301 of the Trade Act of 1974 from 25% to 100% on EVs, bringing total duties to 102.5%, from 7.5% to 25% on lithium-ion EV batteries and other battery parts and from 25% to 50% on photovoltaic cells used to make solar panels. “Certain” critical minerals will have their tariffs raised from nothing to 25%.
The tariffs on ship-to-shore cranes will rise to 25% from zero, those on syringes and needles will rise to 50% from nothing now and some personal protective equipment (PPE) used in medical facilities will rise to 25% from as little as 0% now. Shortages in PPE made largely in China hampered the United States’ COVID-19 response.
More tariffs will follow in 2025 and 2026 on semiconductors, whose tariff rate will double to 50%, as well as lithium-ion batteries that are not used in elective vehicles, graphite and permanent magnets as well as rubber medical and surgical gloves.
A step Biden previously announced to raise tariffs on some steel and aluminum products will take effect this year, the White House said.
A number of lawmakers have called for massive hikes on Chinese vehicle tariffs. There are relatively few Chinese-made light-duty vehicles being imported now. Senate Banking Committee Chairman Sherrod Brown wants the Biden administration to ban Chinese EVs outright, over concerns they pose risks to Americans’ personal data.
U.S. Treasury Secretary Janet Yellen, who warned China in April that its excess production of EVs and solar products was unacceptable, said that such concerns were widely shared by U.S. allies and the actions were “motivated not by anti-China policy but by a desire to prevent damaging economic dislocation from unfair economic practices.”
