HOUSTON Patients admitted to Houston Methodist Hospital get a monitoring device about the size of a half-dollar affixed to their chest and an unwitting role in the expanding use of artificial intelligence in health care.

This story also ran on Fortune. It can be republished for free.

The slender, battery-powered gadget, called a BioButton, records vital signs including heart and breathing rates, then wirelessly sends the readings to nurses sitting in a 24-hour control room elsewhere in the hospital or in their homes. The devices software uses AI to analyze the voluminous data and detect signs a patients condition is deteriorating.

Hospital officials say the BioButton has improved care and reduced the workload of bedside nurses since its rollout last year.

Because we catch things earlier, patients are doing better, as we dont have to wait for the bedside team to notice if something is going wrong, said Sarah Pletcher, system vice president at Houston Methodist.

But some nurses fear the technology could wind up replacing them rather than supporting them and harming patients. Houston Methodist, one of dozens of U.S. hospitals to employ the device, is the first to use the BioButton to monitor all patients except those in intensive care, Pletcher said.

The hype around a lot of these devices is they provide care at scale for less labor costs, said Michelle Mahon, a registered nurse and an assistant director of National Nurses United, the professions largest U.S. union. This is a trend that we find disturbing, she said.

The rollout of BioButton is among the latest examples of hospitals deploying technology to improve efficiency and address a decades-old nursing shortage. But that transition has raised its own concerns, including about the devices use of AI; polls show the public is wary of health providers relying on it for patient care.

In December 2022 the FDA cleared the BioButton for use in adult patients who are not in critical care. It is one of many AI tools now used by hospitals for tasks like reading diagnostic imaging results.

In 2023, President Joe Biden directed the Department of Health and Human Services to develop a plan to regulate AI in hospitals, including by collecting reports of patients harmed by its use.

The leader of BioIntelliSense, which developed the BioButton, said its device is a huge advance compared with nurses walking into a room every few hours to measure vital signs. With AI, you now move from I wonder why this patient crashed to I can see this crash coming before it happens and intervene appropriately, said James Mault, CEO of the Golden, Colorado-based company.

The BioButton stays on the skin with an adhesive, is waterproof, and has up to a 30-day battery life. The company says the device which allows providers to quickly notice deteriorating health by recording more than 1,000 measurements a day per patient has been used on more than 80,000 hospital patients nationwide in the past year.

Hospitals pay BioIntelliSense an annual subscription fee for the devices and software.

Houston Methodist officials would not reveal how much the hospital pays for the technology, though Pletcher said it equates to less than a cup of coffee a day per patient.

For a hospital system that treats thousands of patients at a time Houston Methodist has 2,653 non-ICU beds at its eight Houston-area hospitals such an investment could still translate to millions of dollars a year. Email Sign-Up

Hospital officials say they have not made any changes in nurse staffing and have no plans to because of implementing the BioButton.

Inside the hospitals control center for virtual monitoring on a recent morning, about 15 nurses and technicians dressed in scrubs sat in front of large monitors showing the health status of hundreds of patients they were assigned to monitor.

A red checkmark next to a patients name signaled the AI software had found readings trending outside normal. Staff members could click into a patients medical record, showing patients vital signs over time and other medical history. These virtual nurses, if you will, could contact nurses on the floor by phone or email, or even dial directly into the patients room via video call.

Nutanben Gandhi, a technician who was watching 446 patients on her monitor that morning, said that when she gets an alert, she looks at the patients health record to see if the anomaly can be easily explained by something in the patients condition or if she needs to contact nurses on the patients floor.

Oftentimes an alert can be easily dismissed. But identifying signs of deteriorating health can be tough, said Steve Klahn, Houston Methodists clinical director of virtual medicine.

We are looking for a needle in a haystack, he said.

Donald Eustes, 65, was admitted to Houston Methodist in March for prostate cancer treatment and has since been treated for a stroke. He is happy to wear the BioButton.

You never know what can happen here, and having an extra set of eyes looking at you is a good thing, he said from his hospital bed. After being told the device uses AI, the Montgomery, Texas, man said he has no problem with its helping his clinical team. This sounds like a good use of artificial intelligence.

Patients and nurses alike benefit from remote monitoring like the BioButton, said Pletcher of Houston Methodist.

The hospital has placed small cameras and microphones inside all patient rooms enabling nurses outside to communicate with patients and perform tasks such as helping with patient admissions and discharge instructions. Patients can include family members on the remote calls with nurses or a doctor, she said.

Virtual technology frees up on-duty nurses to provide more hands-on help, such as starting an intravenous line, Pletcher said. With the BioButton, nurses can wait to take routine vital signs every eight hours instead of every four, she said.

Pletcher said the device reduces nurses stress in monitoring patients and allows some to work more flexible hours because virtual care can be done from home rather than coming to the hospital. Ultimately it helps retain nurses, not drive them away, she said.

Sheeba Roy, a nurse manager at Houston Methodist, said some members of the nursing staff were nervous about relying on the device and not checking patients vital signs as often themselves. But testing has shown the device provides accurate information.

After we implemented it, the staff loves it, Roy said. Houston Methodist this year plans to send the BioButton home with patients so the hospital can better track their progress in the weeks after discharge, measuring the quality of their sleep and checking their gait.(Phil Galewitz/KFF Health News)

Serena Bumpus, chief executive officer of the Texas Nurses Association, said her concern with any technology is that it can be more burdensome on nurses and take away time with patients.

We have to be hypervigilant in ensuring that we are nt leaning on this to replace the ability of nurses to critically think and assess patients and validate what this device is telling us is true, Bumpus said.

Houston Methodist this year plans to send the BioButton home with patients so the hospital can better track their progress in the weeks after discharge, measuring the quality of their sleep and checking their gait.

We are not going to need less nurses in health care, but we have limited resources and we have to use those as thoughtfully as we can, Pletcher said. Looking at projected demand and seeing the supply we have coming, we will not have enough to meet demand, so anything we can do to give time back to nurses is a good thing.

Lectric Ebikes may be launching a new XP 4 this week, and it could change everything

Lectric Ebikes appears to be preparing for a major new product launch, teasing what looks like the next evolution of its wildly popular folding fat tire electric bike. Based on the clues, it looks like a new Lectric XP 4 could be inbound.

In a social media post released over the weekend, the company shared a minimalist graphic reading “XP4” along with the message “Tune in 5.6.2025 9:30AM PT.” That date – this Tuesday – suggests we’re just hours away from the big reveal of the Lectric XP 4.

If true, this would mark the next generation of the most successful electric bike in the U.S. market. The current model, the Lectric XP 3.0, has become an icon of accessible, budget-friendly electric mobility. Starting at just $999, the XP 3.0 offers a foldable frame, fat tires, a 500W motor, a rear rack, lights, and hydraulic brakes – all packed into a highly shippable design that arrives fully assembled. It’s the kind of package that has helped Lectric claim the title of best-selling e-bike brand in the U.S. for several years in a row.

With the XP 3.0 still going strong, the teaser raises plenty of questions. Will the XP 4.0 be a modest update or a major leap forward? Could we see new features like torque-sensing pedal assist, a location tracking option, or upgraded performance? Or is Lectric preparing a more comfort-oriented variant, maybe even with upgraded suspension or even more accessories included standard?

The teaser image, which features stylized stripes in grey, blue, and black, may hold some clues. One theory is that the colors represent new trim options or component upgrades. Another possibility is that Lectric is preparing multiple variants of the XP 4.0 – perhaps targeting commuters, adventurers, and off-road riders with purpose-built versions. We took the liberty of a bit of rampant speculation late last year, so perhaps that’s now worth a revisit.

At the same time though, Lectric’s penchant for launching new models at unbelievably affordable prices has never run up against such strong pricing headwinds as those posed by uncertainty in the current US-global trade war fueled by rapidly changing tariffs for imported goods.

Whatever the case, Lectric’s knack for surprising the industry with high-value, customer-focused e-bikes means expectations will be high. The brand has built a loyal following by delivering reliable performance at a price point that few can match, and any major update to the XP lineup is likely to ripple across the market.

As a young and energetic e-bike company, Lectric is also known for throwing impressive parties around the launch of new models. It looks like I may need to hop on a red-eye to Phoenix so I can see for myself – and so I can bring you all along, of course.

Be sure to tune in Tuesday at 9:30AM PT to see what Lectric has in store – and you can bet we’ll have all the details and first impressions as soon as they drop.

Industry calls for urgent crypto law reforms after Australian election

Industry calls for urgent crypto law reforms after Australian election

Industry calls for urgent crypto law reforms after Australian election

The Australian crypto industry has called on the newly reelected Labor government to urgently make digital asset legislation a top priority to ensure Australia doesn’t fall further behind global markets.

The incumbent Australian Labor Party was returned in a landslide on May 3, picking up 54.9% of the two-party-preferred vote, against the Liberal and National Parties on 45.1%. Both parties went to the election promising crypto law reform, but only the opposition pledged to deliver draft legislation within 100 days.

Joy Lam, Binance’s head of global regulatory and APAC legal, said the exchange has been consulting with Treasury officials since late 2023 about its proposed legislation, and it was now time for action.

“Timing is really quite critical now because obviously it’s something that has been discussed and kicked around for quite a few years,” she told Cointelegraph.

Coinbase managing director for APAC John O’Loghlen said the reelected Albanese Government has the “opportunity and the responsibility to move quickly on this issue” and called for a Crypto-Asset Taskforce to be established within its first 100 days “with the aim of bringing forward legislation that protects consumers, promotes innovation, and stops the exodus of talent and capital to other markets.”

BTC Markets CEO Caroline Bowler said that “beyond the political implications, this result sets the stage for meaningful progress in Australia’s approach to digital asset regulation.”

Lam noted that the UK released its draft regulations last week, stablecoin bills are moving forward in the US, and the EU has already implemented its MiCA legislation.

“So there’s a very clear shift. Everyone’s moving towards providing the regulatory framework that is needed for the industry to develop in a sustainable way. So time is really of the essence now.”

Draft crypto legislation within months

Treasurer Jim Chalmers’ office told Cointelegraph that exposure draft legislation would be released sometime this year for consultation, and any legislated reforms would be “phased in over time to minimize disruptions to existing businesses.”

Although the Treasury has draft legislation on “regulating digital asset platforms” and “payments system modernization” scheduled for release by the end of June, Lam isn’t confident. “I don’t know whether this quarter specifically is still sort of the timeline,” she said.

While the ALP has been attacked by some over not taking any action in its first term in government, that may actually have resulted in a better outcome than legislation that took its cues from the approach of Joe Biden’s administration, which took a hard line on banks dealing with cryptocurrency and viewed most coins as securities. 

Industry figures report a noticeable evolution in the government’s approach to crypto between when proposals were first put out for consultation at the end of 2023 and when the Treasury released its much more positive “Statement on Developing an innovative Australian digital asset industry” in March this year.

The statement sets out key priorities, such as using the existing Australian Financial Services License (AFSL) regime to underpin the regulation of Digital Asset Platforms and payment stablecoins. It’s focused on the safe custody of client assets by centralized providers and sidesteps issues around decentralized finance platforms

Lam welcomed the use of the AFSL regime. “Obviously, we don’t need to reinvent the wheel,” she said. “It’s something that people know and understand. It’s a pretty sensible move, and it’s also going to be much easier for regulators.”

Tokenization and sandbox

The government will also review the Enhanced Regulatory Sandbox, which aims to provide space for innovative digital asset startups to grow free of red tape. The statement also highlights opportunities with tokenization.

Lam said the change in emphasis showed the government has been listening to the industry. 

“It reflects the industry feedback that they would have received in 2023 as a result of the consultation, as well as the changing landscape because obviously it’s been evolving pretty quickly internationally,” Lam said.

“They do have the benefit now of looking at what has worked and hasn’t worked in other jurisdictions, and really building on those lessons.”

Dea Markovy, policy director at Fireblocks, told Cointelegraph that “a lot of the groundwork and research is done” and it was looking broadly positive.

“Of course, a lot of details are still to come around Australia’s Digital Asset Platforms (DAPs) regime. What is significant here is the willingness of the Government to cut through the complexity and uncertainty on crypto intermediaries licensing.” 

The securities regulator ASIC released its own crypto regulations proposals (INFO 225) in December, and feedback from those consultations will help inform the government’s new legislation. 

“In essence, it details how different token issuances and crypto intermediation will fit into Australia’s existing securities legislation, providing for a transition period,” explained Markovy.

The draft guidance suggests NFTs, in-game assets and memecoins are not financial products — the local equivalent of a “security” — while a yield-bearing stablecoin or a gold-backed token probably are.

The Treasury statement also highlighted issues with debanking. Lam said that simply regulating the industry would go a long way toward solving the issue.

“What we really want from governments and regulators is that clean licensing framework, because that goes a long way to mitigating the risk and giving the banks the comfort that they need,” she said. “And then, there’s probably going to need to be some additional guidance given to banks.”

At least 15 injured in 'US-British' strike on Yemeni capital, according to Houthi group

Yemen’s Houthi rebel group has said 15 people have been injured in “US-British” airstrikes in and around the capital Sanaa.

Most of those hurt were from the Shuub district, near the centre of the city, a statement from the health ministry said.

Another person was injured on the main airport road, the statement added.

It comes after Israeli Prime Minister Benjamin Netanyahu vowed to retaliate against the Houthis and their Iranian “masters” following a missile attack by the group on Israel’s main international airport on Sunday morning.

It remains unclear whether the UK took part in the latest strikes and any role it may have played.

On 29 April, UK forces, the British government said, took part in a joint strike on “a Houthi military target in Yemen”.

“Careful intelligence analysis identified a cluster of buildings, used by the Houthis to manufacture drones of the type used to attack ships in the Red Sea and Gulf of Aden, located some fifteen miles south of Sanaa,” the British Ministry of Defence said in a previous statement.

On Sunday, the militant group fired a missile at the Ben Gurion Airport, sparking panic among passengers in the terminal building.

The missile impact left a plume of smoke and briefly caused flights to be halted.

Four people were said to be injured, according to the country’s paramedic service.
