Documenting ICD-10 codes has traditionally been a labor-intensive task in health care, but it's a crucial way to track outcomes, mortalities and morbidities in a standardized way, said Dr. Will Morris, the chief medical officer of Ambience.
"If you think about it from a data perspective, it's how you can compare and contrast clinician A to B, or health system A to B," Morris said in an interview. "It's the cornerstone for quality."
Ambience's technology is used at more than 40 health-care organizations, like Cleveland Clinic and UCSF Health. It has raised more than $100 million, according to PitchBook, from investors including Kleiner Perkins, Andreessen Horowitz and the OpenAI Startup Fund.
The company is reportedly seeking fresh capital at a valuation of over $1 billion, according to a report from The Information. Ambience declined to comment on the report.
Ambience trained its new AI model using OpenAI's reinforcement fine-tuning technology. This technology allows companies to tune OpenAI's best reasoning models for very specific domains, like health care.
To validate the model, Ambience tested it against a "gold panel" set of labels, the company said. The labels were established by a group of expert clinicians who evaluated complex clinical cases and came to an agreement on what the right codes were.
The acquisition adds to a slew of deals Salesforce has made over the years as the company has sought to expand its product portfolio and gain market share. It bought Slack in 2021 for $27.7 billion, Tableau in 2019 for $15.7 billion, and MuleSoft in 2018 for $6.5 billion.
Salesforce CEO Marc Benioff said Monday that the firm would look to leverage Informatica alongside its Data Cloud, MuleSoft and Tableau products to "enable autonomous agents to deliver smarter, safer, and more scalable outcomes for every company."
The Trump administration's decision to exempt iPhones and other consumer electronics from his reciprocal tariffs on April 11 did not reverse those trends, with Apple CEO Tim Cook in early may reiterating plans for most iPhone's sold in the U.S. to be manufactured in India.
IPhones imported from China under Trump's current term tariffs still face an additional 30% of duties, while the baseline tariff rate is currently 10% for most other countries, including India.
Omdia estimates that U.S. iPhone demand is about 20 million a quarter, with India expected to be able to match that level only by 2026.
Meanwhile, Daniel Newman, CEO and principal analyst at research firm Futurum Group, noted that shipment numbers reflect final assembly, but are not representative of the entire supply chain and manufacturing process.
"It was actually a very low lift for them to migrate more and more of the final assembly from China to India," he said, adding that a vast majority of the sub-assemblies are all still in China.
At the core of PRAD is an innovative receiver with a compact aperture that captures incoming laser light with minimal loss. Once inside, the beam hits a parabolic mirror and is directed onto an array of photovoltaic cells, efficiently converting the laser energy back into usable electrical power, reports PV Magazine.
This demonstration marks a critical milestone for enabling rapid, on-demand energy delivery in military environments. The PRAD technology is scalable and designed for integration into various platforms, including UAVs, potentially eliminating the need for traditional fuel logistics in the field.
“It’s a lot easier to send a power beam directly up or down relative to the ground because there is so much less atmosphere to fight through. For PRAD, we wanted to test under the maximum impact of atmospheric effects,” Jaffe said.
While efficiency wasn’t the main objective, the team recorded over 20 percent conversion efficiency from laser to electrical power at shorter distances.
According to DARPA, the primary goal was to rapidly validate a new receiver design capable of extending transmission range, even if it meant trade-offs in efficiency. Impressively, the receiver was designed and built in just three months.
“This demonstration broke through misconceptions about the limits of power beaming technology, and it is already spurring industry to reimagine what’s possible,” said Jaffe in a statement.
The receiver, which could be scaled for UAVs, was developed by US-based Teravec Technologies, with support from Packet Digital and the Rochester Institute of Technology, reports PV Magazine.
The merger timing coincides with Hygon’s most ambitious processor announcement yet—the upcoming C86-5G processor. The CPU features 128 cores, capable of running 512 simultaneous threads through four-way simultaneous multithreading (SMT4).
In other words, this means that the CPU can run 512 operations or processes simultaneously. This roughly doubles the processing power offered by commercial Intel and AMD CPUs, which use two-way SMT.
Beyond threading, the C86-5G delivers a 17% improvement in instructions per cycle compared to its predecessor. This points to architectural improvements beyond adding cores to the CPU.
The processor also supports massive amounts of memory (up to 1TB) and modern connectivity features, putting it on par with current Intel and AMD chips.
According to the team, these layers can reduce engine noise by up to 26 decibels (dB) together, which is a significant acoustic improvement. A 10dB reduction in underwater noise can cut detection range by roughly 32 percent.
So, 26dB reduction could more than halve a submarine’s sonar detection range. This targets low-frequency tonal noise, the primary way submarines are detected by sonar.
For reference, most modern submarines, especially American ones, typically have acoustic signatures between 90 dB (Ohio-class) and 130 dB (older Los Angeles-class). With ambient sea noise at between 85–95 dB due to waves, marine life, and other vessels, anything close to this effectively allows a submarine to “hide in the noise.”
“During low-speed navigation, mechanical noise generated by power equipment operation constitutes the primary noise source for underwater vehicles, serving as their key acoustic signature for detection – typically manifested as a series of low-frequency tonal components,” the researchers said.
“Implementing vibration-damping measures to diminish energy transmission from engines through supporting structures is crucial for enhancing underwater vehicles’ acoustic stealth performance,” they added.
During testing, a scaled-down model with the new technology reduced noise levels by 24dB (12dB passive plus 12dB active) at 100 Hz and 26dB at 400 Hz.
According to the team, the system has an effective bandwidth of 10–500Hz. This, they explain, should cover most typical engine harmonics, while real-time noise cancellation was possible thanks to the system’s extremely short response time, according to the study.
Airvolve wants to build a ten times cheaper platform to operate than the current rotorcraft. The Airlift will carry up to 200 kg (441 pounds) of cargo, with five cubic meters of internal volume and a range of 100 km (62 miles).
It will support logistics, evacuation, and other tactical operations using existing military infrastructure, with no special charging systems or pilot training required.
A major innovation is in the aircraft’s rotor design. Instead of traditional vertical-axis rotors, the Airlift uses a pair of horizontal-axis rotors, which Gendvilas describes as “helicopter blades that fold like a big umbrella.”
This configuration, originally explored by Boeing in the 1930s, was abandoned due to material limitations. Airvolve believes modern composites now make this design viable.
UK’s Ministry of Defense is already using AI to an advanced level, with more than 200 scientists joining the military personnel. They recently conducted their largest-ever AI trial across land, sea, and air across a five-day exercise. The aim was to test how fast AI algorithms developed by Thales could identify and neutralize enemy targets.
On the other hand, the British Navy also intends to use AI to track movements of Russian submarines, according to reports. Their SG-1 Fathom autonomous vehicles will have an AI model trained on the acoustic signature of various vessels, submarines, and marine life.
"The rebound was already visible before the May 12 US-China trade deal but gained momentum afterwards," said Stephanie Guichard, senior economist, global indicators at the Conference Board. "Write-in responses on what topics are affecting views of the economy revealed that tariffs are still on top of consumers' minds."
Ambience announces OpenAI-powered medical coding model that outperforms physicians
Ambience is part of the red-hot market that uses AI to draft clinical notes in real time as doctors consensually record their visits with patients
Artificial intelligence startup Ambience Healthcare on Tuesday announced a new medical coding model that outperforms doctors by 27%.
Ambience uses AI to draft clinical notes in real-time as doctors consensually record their visits with patients. The company used tools from OpenAI to build the new model.
The startup is part of a fiercely competitive market that has taken off as health-care executives search for solutions to help reduce staff burnout and daunting administrative workloads.
The company's new model can listen to patient encounters and identify ICD-10 codes, which are internationally standardized classifications for different diseases and conditions. There are about 70,000 ICD-10 codes that are regularly updated and used to facilitate billing and other reporting processes in health care.
Ambience said its new ICD-10 model can reduce billing mistakes and help clinicians and professional coders work more efficiently. The model notched a "27% relative improvement over physician benchmarks," according to a release on Tuesday.
"We're not replacing doctors or coders," Brendan Fortuner, Ambience's head of engineering, told CNBC in an interview. "What we're doing is we're liberating them from administration, and we're fixing mistakes that help make health care better, safer, more cost-effective."

Salesforce to acquire data management company Informatica in $8 billion deal
Salesforce is buying cloud data management firm Informatica to bolster the enterprise software giant's push into artificial intelligence.
Salesforce announced Tuesday that it's buying cloud data management firm Informatica in an $8 billion deal to bolster the enterprise software giant's push into artificial intelligence.
Shares of Salesforce were up about 1% in U.S. premarket trading. Informatica shares climbed about 6%.
"Truly autonomous, trustworthy AI agents need the most comprehensive understanding of their data," said Steve Fisher, Salesforce president and chief technology officer, in a release. "The combination of Informatica's advanced catalog and metadata capabilities with our Agentforce platform delivers exactly this."
Under the terms of the deal, holders of Informatica's Class A and Class B-1 common stock will receive $25 in cash per share, according to a press release announcing the deal.
Salesforce, which specializes in customer relationship management software, said that it would look to combine Informatica's data catalog, integration, governance, privacy and data management services with its agentic AI solution, dubbed Agentforce.
The deal will be funded through a combination of cash on Salesforce's balance sheet and new debt, the company said.
India's iPhone exports to the U.S. soared an estimated 76%. But Trump, Beijing won't make further growth easy
Shipments of iPhones from India to the U.S. rose 76% in April year on year, estimates from a technology market analyst firm shows.
Shipments of iPhones from India to the U.S. rose 76% in April year on year, estimates from a technology market analyst firm shows. The surge comes as Apple accelerates its "made in India" plans, which analysts say will meet pushback from President Donald Trump and Beijing.
The data from Canalys, now part of Omdia, showed that U.S. iPhones shipped from India in April reached roughly 3,000,000. That's a stark contrast to shipments from China over the same period, which fell about 76% from last year to just 900,000.
According to Le Xuan Chiew, a research manager at Omdia, the April numbers show the aggressive measures Apple has taken to adapt to Washington's tariffs against China, where Apple manufactures most of its iPhones.
"This latest trade war with China, is the type of disturbance that Apple has long been trying to prepare itself for," he said, adding that the country had first started investing heavily into supply chains in India during the Covid-19 pandemic.
India also surpassed China in iPhone shipments to the United States in March, according to Omdia's estimates. The uptick came ahead of Trump's first iteration of "reciprocal tariffs" on April 2. The amount of shipments that month was unusually high and appeared to be the result of the company's stockpiling, according to Chiew.
Powerful US military laser fires 800-watt beam over record breaking 5.3 miles
PRAD demo enables fast, on-demand energy delivery, scalable for platforms like UAVs, reducing reliance on fuel logistics in the field.
The US Defense Advanced Research Projects Agency (DARPA) has achieved a major milestone in wireless energy transmission.
The agency claims it is setting new records in its latest test campaign under the Persistent Optical Wireless Energy Relay (POWER) program.
Tests demonstrated the successful delivery of over 800 watts of power during a 30-second laser transmission from 5.3 miles (8.6 kilometers) away in New Mexico. Throughout the campaign, more than a megajoule of energy was transferred using advanced optical power-beaming technology.
According to DARPA, the breakthrough marks a significant step in developing long-range, wireless energy solutions for defense and other critical applications.
“It is beyond a doubt that we obliterated all previously reported optical power beaming demonstrations for power and distance,” said Paul Jaffe, Program Manager of POWER, in a statement.
Laser power breakthrough
Military operations rely heavily on energy, but delivering it to remote locations like battlefields or disaster zones is often slow, risky, and resource-intensive.
In a significant test for the POWER program, researchers successfully demonstrated a ground-based laser power transmission system known as the POWER Receiver Array Demo (PRAD). The test focused on beaming energy through the densest part of the atmosphere—a major technical challenge—and still managed to set new records in power and distance.
China allegedly making its own supercomputer chips to cut dependence on US tech
The new Hygon C86-5G processor offers 128 cores and 512 simultaneous threads, doubling processing power over typical Intel and AMD CPUs.
Supercomputers have been a powerful tool ever since their birth in the 1960s. Today, almost every nation has advanced supercomputing facilities and systems capable of solving the most complex of tasks.
Chinese semiconductor manufacturer Hygon and supercomputer builder Sugon have announced the creation of a vertically integrated computing giant capable of building high-performance systems entirely with domestic technology.
The processor is a result of the stock swap merger between the two companies. This gives China control over both the chip design and supercomputer manufacturing.
The process began in 2016 when Hygon licensed AMD’s first-generation Zen CPU design and x86-64 architecture. This is the most commonly used architecture for processors in computing today.
Hygon used the original license to develop its Dhyana processor series, which gained support from Linux kernel developers and adoption by Chinese tech giants like Tencent.
Meanwhile, Sugon used the Dhyana processor to make a machine that ranked in the Top 500 list of the world’s most powerful supercomputing systems.
This partnership proved successful.
Report: Apple to Unveil 'Solarium' UI Overhaul for All Devices at WWDC
Apple plans to introduce a design overhaul for all of its operating systems at WWDC. The updated interface, codenamed 'Solarium', will give the operating systems a more slick and modern appearance. It borrows a lot of elements from visionOS. The UI overhaul will be the biggest for iPhones since iOS 7 in 2013 and for Macs since macOS Big Sur in 2020.
SpaceX Pushes to Get Starship Rocket Ready for Mars by Next Year
SpaceX has been moving more employees into Starship roles in recent months. The space company has also been making big investments in its complex in Texas for the vehicle and has similar plans for Florida. It is behind schedule on a variant of Starship for a NASA mission to the moon currently set for 2027. SpaceX has been struggling this year, with back-to-back Starship flight tests that ended in explosions.
Should Everyone Be Taking Ozempic? Doctors Say More People Could Benefit
The number of diseases that the GLP-1 category of drugs seems to be effective in treating is expanding rapidly. The drug could be beneficial to a third to a majority of adults. Many of the proven and potential benefits of the drugs cascade from their effect on obesity, but some are independent of weight loss, possibly from the anti-inflammatory effects of the drugs.
Stealthier submarines: China’s new tech could cut vessel’s engine noise by 50%
The new technology can allegedly reduce submarine engine noise by as much as 32%, perhaps even 50%.
Chinese scientists have allegedly made a major breakthrough in submarine stealth technology. According to reports, the team has developed a hybrid active-passive engine vibration isolation system designed to reduce submarines’ acoustic signature significantly.
Zhang Zhiyi and his team at Shanghai Jiao Tong University conducted the research, with support from the China State Shipbuilding Corporation, a major player in Chinese naval construction.
The team’s innovation centers around a new vibration-damping system that can dramatically reduce the submarine’s underwater acoustic signature. This system consists of two main layers: active and passive.
The first uses a set of steel-rubber-steel sandwich rings to absorb vibrations. This is a significant improvement over more traditional, rigid engine mounts found in most submarines.
The latter uses twelve or so piezoelectric actuators placed around the engine to counteract vibrations in real time. These actuators can neutralise the engine’s micron-level movements with strong control forces through precision lever mechanisms.
TSMC Bets On Unorthodox Optical Tech
TSMC is working with startup Avicena to produce microLED-based interconnects. The technology is designed to meet the high needs of communication among an increasing number of GPUs in a low-cost, energy-efficient way. AI clusters are facing unprecedented requirements - sooner or later, the copper wires that connect processors and memory within a single AI data rack will have to be replaced with optics. Avicena's approach is very unorthodox, but it is ideal for these short-distance applications.
Ask HN: Anyone struggling to get value out of coding LLMs?
While some engineers can't seem to stop raving about how much of a superpower large language models are for coding, others find it to be an extremely finicky process that requires an extreme amount of coddling to get average results at best. This could be because of the type of work the engineers are doing - AI seems to be productive for greenfield work, but it is pretty useless when it comes to maintaining existing systems, adding more complicated features, or needing to know business domain details. Some engineers find it much quicker and easier to just write code themselves as they always do a better job in the end.
Big Banks Explore Venturing Into Crypto World Together With Joint Stablecoin
The biggest banks in the US are in discussions about whether to team up and issue a joint stablecoin. The talks are in early stages and any final decision would depend on how stablecoins will be legislated. Banks have been bracing for the possibility that stablecoins could become widely adopted under President Trump. Stablecoins could speed up more routine transactions, but there is still some skepticism about the security of the technology and the regulatory implications of getting involved with digital assets.
Crypto industry urges SEC to clarify staking stance
Crypto industry groups, led by the Crypto Council for Innovation, are urging the SEC to issue formal guidance on staking amid ongoing regulatory uncertainty for web3 infrastructure providers. While the SEC has recently clarified that memecoins and stablecoins are not securities, it has yet to define compliant staking frameworks or approve staking in ETFs. The industry is optimistic about upcoming staking-enabled cryptocurrency ETFs and continues productive meetings with the agency. At the same time, firms are pushing back against the IRS' classification of staking rewards as service income.
Trump crypto dinner guest describes ‘worst food’ ever and ‘bullshit’ speech
A TikTok prankster who paid ~$300,000 for a seat at Trump's memecoin holder dinner called the three-course meal “trash,” likening the filet mignon to “Walmart steak.” He also dismissed Trump's brief, scripted speech praising crypto as “something special” as “pretty much like bullshit,” noting the president departed before presenting watches to top token holders. Other attendees described the food as merely “OK” and reported similar disappointment with the event's organization. Meanwhile, 35 Democratic lawmakers are urging a Justice Department probe into potential foreign-emoluments violations stemming from the international guest list.
Lagrange Token Launch
Lagrange has launched $LA, its native token used to pay for cryptographic proofs that power things like ZK rollups and verifiable AI. Clients pay fees (in $ETH, $USDC, or $LA), and the system converts those into $LA to reward provers, creating steady demand for the token. Token holders can stake or delegate $LA to support specific provers, helping scale the network while reducing supply and boosting long-term value.
20-foot flying ‘container’ robot drone could become future helicopter, cut costs by 90%
The Airlift is aimed at being cheaper, simpler, and safer than helicopters and large drones.
Lithuanian start-up Airvolve is working on a next-generation aircraft that could replace traditional helicopters in military missions.
Aviation International News (AIN) recently reported that the company’s Airlift design is a hybrid-electric aircraft meant to carry cargo, evacuate casualties, and operate in hostile environments at a fraction of the cost of existing rotorcraft.
It is being developed for countries like Ukraine, Greece, Poland, and Lithuania, where armed forces seek cost-effective and survivable platforms.
Airvolve plans to build a full-scale prototype this year to demonstrate its potential to European defense partners.
Airvolve CEO Donatas Gendvilas told AIN that recent combat scenarios and disaster events have highlighted the need for new aircraft types.
The evacuation of Ukrainian forces from Mariupol and wildfires around the Mediterranean showed that helicopters are vulnerable and expensive.
“Some of our partners now say helicopters are history,” Gendvilas said. He added that cheap, shoulder-fired missiles can take down many helicopters.

How to protect yourself after a personal data breach: 5 steps
If your personal data is exposed in a breach, attackers can use it to escalate their access through phishing, identity theft, and account takeovers. To protect yourself, take immediate action: freeze your credit, strengthen MFA, replace compromised IDs, secure key accounts (Apple, Google, etc), use a password manager, and lock down your phone. Stay vigilant for scams, monitor your social media, and treat cybersecurity as a necessity, not an option.
Sui validators freeze majority of stolen funds in $220M Cetus hack
Validators on the Sui network have frozen approximately $162 million of the $223 million stolen from the Cetus DEX on May 22 and are working alongside the Cetus team and the Sui Foundation to recover the remaining funds. The exploit drained user assets via a smart-contract vulnerability, with $63 million bridged to Ethereum and 20,000 ETH (≈$53 million) laundered through a single wallet. While the asset freeze offers relief to victims, some community members have raised concerns about censorship resistance, noting that 114 validators could unilaterally block transactions.
UK’s Royal Navy to use AI for ‘hostile’ threats, including Russian movements in Arctic
Russia’s growing influence in the Arctic is a safety concern for the UK and Europe.
Russia’s war efforts in Ukraine show no signs of slowing down any time soon. The UK has now gone on alert regarding the Russians’ hostile activities in Arctic, posing a threat to the former and other European nations in the region.
According to reports, the UK is now considering use of AI to detect Russia’s hostile activities in the Arctic.
Furthermore, they are also focusing on strengthening ties with neighboring nations like Iceland so as to fight the Russians collectively.
The Arctic region is a very important area for Europe and the UK from a safety point-of-view, which justifies the former’s growing concerns. Russia’s actions in the Arctic are majorly helping their war in Ukraine, but there’s more to the story for Britain’s worries.
Apparently, Russia’s activities could also put important things like – undersea internet and communication cables that connect to the UK – at risk. The UK is teaming up with Iceland to combat this threat.
UK Foreign Secretary, David Lammy, said that they will announce a new joint scheme with Iceland to use cutting-edge AI technology to monitor Russia’s activities.
Mr Lammy said: “It’s more important than ever that we work with our allies in the High North, like Norway and Iceland, to enhance our ability to patrol and protect these waters.”
Transitioning onchain skeptics to believers
In under seven days, a developer went from rejecting crypto payments to praising the speed and cost savings after using onchain transfers via Base.
