Many Americans rely on their Apple Watches or similar devices each day to count their steps, track workouts, and measure how many calories they burn. But are those wearable devices accurate?

University of Mississippi professor Minsoo Kang and doctoral student Ju-Pil Choe are working to answer that question.

Kang, a professor of sports analytics, and Choe reviewed 56 studies that compared the Apple Watch to trusted reference tools in measuring energy burned, heart rate and step counts.

Data from the National Institutes of Health shows that wearable technology has become increasingly popular across all types of users, from elite athletes to the general population, whether active or sedentary. As early as 2015, about 1 in 8 Americans reported using a wearable activity monitor. By 2019, wearable tech had become the top fitness trend, and the market continues to expand.

“If people are using them to make decisions about their workouts or even medical conditions, the data should be accurate,” Choe said. “If the numbers are off, it could lead to confusion, overtraining or even missed health warnings.”

The Ole Miss researchers conducted a meta-analysis to evaluate how the device’s accuracy varied by age, health status, Apple Watch version and type of physical activity.

The findings showed that Apple Watches are generally accurate when measuring heart rate and step counts. The researchers reported mean absolute percent errors, a standard measure of accuracy, of 4.43% for heart rate and 8.17% for step counts, while the error for energy expenditure rose to 27.96%.

This inaccuracy was observed across all types of users and activities tested, including walking, running, cycling and mixed-intensity workouts.

The results indicated that Apple Watches can be a good support tool, such as for tracking basic activity after surgery, but they should not replace clinical tools or medical judgment, Kang said.

“These devices are great for keeping track of habits and staying motivated,” he said. “But do not take every number as 100% truth, especially the calories. Think of it as a helpful guide, not a diagnostic tool. It is useful but not perfect.”

The researchers noted that newer models seem to be more accurate.

“While we cannot say every update is a big leap forward, there is a noticeable trend of gradual improvements over time,” Choe said. “It shows that Apple is refining the technology over time.”

Kang said he hopes this study will help consumers make informed choices about buying and using wearable devices and help manufacturers improve the technology people rely on daily.

“By showing where the weaknesses are, we can help developers get real feedback,” he said. “If they know what needs to be fixed, they can design better sensors or algorithms. “Our findings can guide improvements and help make these devices more useful for both everyday users and health care providers.”

The study is published in the journal Physiological Measurement.

WASHINGTON (AP) — Meta has cut a 20-year deal to secure nuclear power to help meet surging demand for artificial intelligence and other computing needs at Facebook’s parent company.

The investment with Meta will also expand the output of a Constellation Energy Illinois nuclear plant.

The agreement announced Tuesday is just the latest in a string of tech-nuclear partnerships as the use of AI expands. Financial details of the agreement were not disclosed.

Constellation’s Clinton Clean Energy Center was actually slated to close in 2017 after years of financial losses but was saved by legislation in Illinois establishing a zero-emission credit program to support the plant into 2027. The agreement deal takes effect in June of 2027, when the state’s taxpayer funded zero-emission credit program expires.

With the arrival of Meta, Clinton’s clean energy output will expand by 30 megawatts, preserve 1,100 local jobs and bring in $13.5 million in annual tax revenue, according to the companies. The plant currently powers the equivalent of about 800,000 U.S. homes. George Gross, professor of electrical and computer engineering at the University of Illinois. estimates that 30 additional megawatts would be enough to power a city with about 30,00 residents for one year.

“Securing clean, reliable energy is necessary to continue advancing our AI ambitions,” said Urvi Parekh, Meta’s head of global energy.

BILLERICA, Mass.–(BUSINESS WIRE)–Jun 3, 2025–

Bruker Corporation (NASDAQ: BRKR) today announced that its Applied Mass Spectrometry (Applied MS) division will present a powerful lineup of innovations at the 73rd American Society for Mass Spectrometry (ASMS) Conference, taking place June 1–5, 2025, in Baltimore, Maryland. These developments reflect Bruker’s continued investment in applied markets, particularly in therapeutic drug monitoring (TDM), drugs of abuse (DoA) analysis and environmental analysis.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250603080303/en/

RECIPE kits for clinical laboratories

Bruker Applied MS will showcase two significant innovations: the integration of RECIPE’s ClinMass ® and ClinDART ® assay kits with Bruker’s EVOQ ® DART-TQ⁺ system for TDM and DoA applications, and the launch of the new timsMetabo™ platform for advanced small molecule analysis. These developments support Bruker’s goal of delivering practical, high-performance solutions for routine analytical challenges.

Bruker’s recent majority investment in RECIPE, a renowned manufacturer of diagnostic assays for small molecule analysis used with triple quadrupole mass spectrometers, marks an important step in expanding its capabilities in TDM and DoA analysis. Since the acquisition, Bruker and RECIPE have collaborated to verify the IVDR certified ClinMASS ® kits for use on the EVOQ DART-TQ⁺ system, initially targeting high-priority compound classes. They are not US-FDA approved, but single compounds as controls and calibrators may be a basis in LDT approaches. In parallel, the companies are preparing the launch of RECIPE’s ClinDART ® kits, which are designed as high-throughput, chromatography-free assays for the EVOQ DART-TQ⁺ system. These kits enable rapid, cost-efficient analysis with highly reduced solvent consumption, ease of use and increased lab productivity. All ClinDART ® protocols are currently designated for Research Use Only (RUO).

Meanwhile, the newly introduced timsMetabo™ platform represents a leap forward in small molecule analysis. Built on Bruker’s proprietary trapped ion mobility spectrometry (TIMS) and enhanced with Mobility Range Enhancement (MoRE) and the Athena Ion Processor (AIP), timsMetabo™ delivers high sensitivity and selectivity for PFAS detection. In early studies, timsMetabo™ identified 40% more low-mass molecules in water samples compared to previous-generation systems. This innovation supports both regulatory compliance and proactive environmental monitoring, with promising applications in toxicology and forensic science.

“The integration of RECIPE’s assay expertise with Bruker’s DART triple quad instrumentation is a significant advancement for therapeutic drug monitoring,” said Dr. Gernot Wolfram, Managing Director of RECIPE. “It represents a promising concept with the potential to enable laboratories to adopt high-throughput, chromatography-free workflows that are efficient, robust, and more sustainable. These could dramatically enhance overall lab productivity and make mass spectrometry more accessible and impactful in routine clinical settings.”

“ASMS 2025 marks an important milestone for Bruker Applied MS,” said Jeffrey Zonderman, Senior Vice President of Bruker Applied Mass Spectrometry. “With the launch of timsMetabo™ and the strategic integration of RECIPE, we are not only expanding our technology portfolio but also redefining what’s possible in applied markets. These innovations reflect our commitment to solving real-world analytical challenges in TDM and environmental analysis.”

Looking ahead, Bruker Applied MS will continue to develop solutions for PFAS, forensic toxicology, and therapeutic drug monitoring. The timsMetabo™ platform is expected to support future applications involving low-mass drug metabolites and emerging contaminants, while RECIPE’s assay pipeline will further enhance Bruker’s applied market offerings.

WASHINGTON — (AP) — Meta has cut a 20-year deal to secure nuclear power to help meet surging demand for artificial intelligence and other computing needs at Facebook’s parent company.

The investment with Meta will also expand the output of a Constellation Energy Illinois nuclear plant.

The agreement announced Tuesday is just the latest in a string of tech-nuclear partnerships as the use of AI expands. Financial details of the agreement were not disclosed.

Constellation’s Clinton Clean Energy Center was actually slated to close in 2017 after years of financial losses but was saved by legislation in Illinois establishing a zero-emission credit program to support the plant into 2027. The agreement deal takes effect in June of 2027, when the state’s taxpayer funded zero-emission credit program expires.

“Securing clean, reliable energy is necessary to continue advancing our AI ambitions,” said Urvi Parekh, Meta’s head of global energy.

Surging investments in small nuclear reactors comes at a time when large tech companies are facing two major demands: a need to increase their energy supply for AI and data centers, among other needs, while also trying to meet their long-term goals to significantly cut greenhouse gas emissions.

Constellation, the owner of the shuttered Three Mile Island nuclear power plant, said in September that it planned to restart the reactor so tech giant Microsoft could secure power to supply its data centers. Three Mile Island, located on the Susquehanna River just outside Harrisburg, Pennsylvania, was the site of the nation’s worst commercial nuclear power accident in 1979.

Also last fall, Amazon said it was investing in small nuclear reactors, two days after a similar announcement by Google. Additionally, Google announced last month that it was investing in three advanced nuclear energy projects with Elementl Power.

U.S. states have been positioning themselves to meet the tech industry’s power needs as policymakers consider expanding subsidies and gutting regulatory obstacles.

Last year, 25 states passed legislation to support advanced nuclear energy, and lawmakers this year have introduced over 200 bills supportive of nuclear energy, according to the trade association Nuclear Energy Institute.

Advanced reactor designs from competing firms are filling up the federal government’s regulatory pipeline as the industry touts them as a reliable, climate-friendly way to meet electricity demands from tech giants desperate to power their fast-growing artificial intelligence platforms.

Still, it’s unlikely the U.S. could quadruple its nuclear production within the next 25 years, like the White House wants. The United States lacks any next-generation reactors operating commercially and only two new large reactors have been built from scratch in nearly 50 years. Those two reactors, at a nuclear plant in Georgia, were completed years late and at least $17 billion over budget.

Amazon, Google and Microsoft also have been investing in solar and wind technologies, which make electricity without producing greenhouse gas emissions.

Shares of Constellation Energy Corp., based in Baltimore, were flat Tuesday.
