Here are the new features landing on your iPhone with iOS 16.3.

Security keys come to Apple ID

Users can now use third-party security keys instead of two-factor authentication for their Apple ID. 

Security keys are a lot like keys to your home. You still use passwords, but this extra layer of security can help protect you against phishing scams and hackers.

“Hardware security keys are very, very secure,” Diya Jolly, chief product officer of authentication service company Okta, told CNET’s Stephen Shankland.

Apple’s security keys feature only works with FIDO Alliance-certified security keys.

Support for the second-gen HomePod

Apple’s iOS 16.3 software adds support for the second-generation HomePod, which is out now and costs $299 (ÂŁ299, AU$479). Apple announced the release of the new HomePod four days before the latest iOS software was made available.

The latest iOS update includes a new iPhone wallpaper as part of Apple’s Black Unity Collection. The collection celebrates Black History Month with a special-edition Apple Watch Black Unity Sport Loop, a mosaic watch face and the new iPhone wallpaper. Apple also plans to release a selection of Black History Month content for Apple TV, Fitness Plus, Music, Maps, Books, Podcasts and the App Store as part of the collection.

New ways to use Emergency SOS via satellite

Emergency SOS via satellite was introduced at Apple’s event in September. In iOS 16.3, the Call with Hold option has been replaced with Call with Hold and Release. If you enable Call with Hold and Release, you can hold the side button and a volume button to initiate a countdown and an alarm. After the countdown, you release the buttons and your iPhone will call emergency services on its own. Before with Call with Hold, pressing the side button and a volume button would first bring up the Emergency SOS call slider. If you continued to hold the buttons, a countdown started and an alarm would go off. After the countdown ended, your phone would make an emergency call.

There’s also an option to Call Quietly in Emergency SOS. By enabling this option, when you try to make an emergency SOS call, your phone won’t start flashing or making an alarm sound.

Here is Apple’s list of new features and changes included in iOS 16.3:

  • New Unity wallpaper honors Black history and culture in celebration of Black History Month.
  • Security Keys for Apple ID allow users to strengthen the security of their account by requiring a physical security key as part of the two factor authentication sign in process on new devices.
  • Support for HomePod (second generation).
  • Emergency SOS calls now require holding the side button with the up or down volume button and then releasing in order to prevent inadvertent emergency calls.
  • Fixes an issue in Freeform where some drawing strokes created with Apple Pencil or your finger may not appear on shared boards.
  • Addresses an issue where the wallpaper may appear black on the Lock Screen.
  • Fixes an issue where horizontal lines may temporarily appear while waking up iPhone 14 Pro Max.
  • Fixes an issue where the Home Lock Screen widget does not accurately display Home app status.
  • Addresses an issue where Siri may not respond properly to music requests.
  • Resolves issues where Siri requests in CarPlay may not be understood correctly.

Iran says it destroyed U.S. advanced drone over Hormuz as Middle East conflict intensifies

Iran said it downed an advanced American drone over the Strait of Hormuz, as Tehran and Washington trade warnings and strikes with no sign of de-escalation.

Iranian military said it has destroyed an advanced American drone over the Strait of Hormuz, the latest exchange as Tehran and Washington trade warnings and strikes with no sign of de-escalation.

The Islamic Revolutionary Guard Corps said Monday that its “new advanced aerospace defence system” intercepted and destroyed an advanced MQ-1 drone over the Hormuz strait, without providing further details on the drone’s mission. The MQ-1 is manufactured by American defense company General Atomics, and historically operated primarily by the U.S. Air Force and the CIA.

The incident followed a series of Iranian operations against U.S. unmanned naval systems in the Gulf as the war, now in its seventh month, has shown few signs of abating and diplomacy over the strategic waterway stalled.

On Sunday, President Donald Trump said the U.S. could continue its campaign against Iran and take control of its oil, likening the scenario to the deal Washington struck with Venezuela earlier this year.

“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump said of the Iran conflict Sunday at the Irish Open golf championship in Ireland. He added that U.S. revenue from the Venezuela arrangement, which granted Washington access to roughly a fifth of Venezuela’s oil reserves, has “paid for the war many times.”

Under the agreement reached in August, Venezuela ceded majority U.S. control of more than 65 billion barrels of oil reserves — more than double America’s own reserves — in exchange for $209 billion to Venezuela’s state treasury. Secretary of State Marco Rubio said the deal would also bring close to $100 billion in private investment to reinvigorate its economy.

On Sunday, Trump said he expects the seven-month Iran war to end this year, possibly after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once it does.

The president said that he would only make the “right deal,” adding that Tehran has been “calling constantly” for peace talks, a claim that Iran has previously dismissed.

Stalled Hormuz talks

A meeting in Oman between Gulf countries and Iran to discuss possible agreements on the Strait of Hormuz, the vital waterway for global oil and gas flows, has been postponed, Omani foreign minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”

Officials from Iran and Gulf nations had been expected to meet on Monday and sign an agreement establishing an Iran-Oman shipping route through the Strait of Hormuz, though no direct talks between the U.S. and Iran were ongoing.

The Strait of Hormuz has been subjected to an Iranian and later U.S. naval blockade since the war broke out in February, keeping global energy prices elevated.

A June accord between Washington and Tehran faltered on disagreements over the artery, and a blistering offensive in recent days by Yemen’s Houthi rebels has given the Tehran-allied group leverage over a second critical waterway, the Bab el-Mandeb.

Ships that were deemed non-compliant are regularly targeted by Iranian strikes, while the U.S. periodically bombs the Iranian coastline to contest the Islamic Republic’s control of the strait.

Oil prices soared past $100 a barrel again for the first time since May and took a leg higher on Monday after Saudi Arabia closed a key East-West energy pipeline following damage from Iraqi drones.

U.S. West Texas Intermediate futures were up 2.3% to $102.39 per barrel. Brent crude, the international benchmark, traded 2.4% higher to $107.11 a barrel.

Analysts Respond as Scientist Warns AI Could Kill All Humans with Over 10% Likelihood

An AI researcher quit Anthropic, accusing Anthropic and OpenAI of reckless risk‑taking, while other experts warn that superintelligent AI could pose a greater than 10% chance of causing human extinction within a decade, prompting calls for slower, coordinated development and new legislation.

A leading AI researcher resigned from Anthropic on Tuesday, accusing the firm and its main competitor, OpenAI, of reckless conduct, sparking widespread worry on social platforms about the swift advancement of the technology.

Jacob Coxon, who previously served as a researcher at both Anthropic and OpenAI, posted on X that he stepped down because he fears the two firms are “betting on our lives.” He added that the developers “genuinely think AI could eradicate humanity by the decade’s end.”

“Don’t underestimate this technology,” the researcher warned. “Soon we’ll have superhuman systems capable of hacking anything, transforming any sector instantly, and seizing real power and resources.”

Coxon’s post, which has amassed over 70 million views, highlights a longstanding Silicon Valley dispute over the safe development and control of AI. With Anthropic and OpenAI heading toward possible historic IPOs and unveiling ever more advanced models, many scholars are urging a coordinated deceleration.

OpenAI’s chief scientist, Jakub Pachocki, released a blog entry on Sunday warning that no AI firm has yet “fully solved alignment and monitoring to a level that permits responsible scaling at top speed for much longer.” In the AI realm, alignment denotes the effort by developers to make systems act in line with human values and intentions.

“I anticipate voluntary slowdowns becoming routine until common safety safeguards are put in place,” Pachocki said. “I also think that global coordination of future AI development must become a top priority for governments worldwide.”

Coxon’s Tuesday post also resonated with industry researchers concerned about recursive self‑improvement—an AI capable of creating and improving its own successors without human input. Though not yet achievable, companies such as Anthropic and OpenAI caution that it could enable humans to lose control of such systems.

“Neither company is acting responsibly,” Coxon asserted. “They are racing directly toward self‑improving superintelligence.”

Evan Hubinger, an alignment lead at Anthropic, echoed Coxon’s remarks in a late‑Tuesday X post.

“Jacob is right—we truly believe AI could eradicate humanity! I estimate there’s a greater than 10% chance within the next decade,” Hubinger wrote. “Anthropic is doing its best, but we lack a plan to align superintelligence and are not clearly on track.”

Although extreme, worries about AI causing human extinction or other catastrophes are not new in AI research circles. In 2023, for example, leading AI researchers and executives—including OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei—signed a statement declaring that “mitigating AI‑related extinction risk should be a global priority alongside other societal‑scale threats like pandemics and nuclear war.”

Some experts even employ the shorthand p(doom) to gauge the likelihood of dire outcomes stemming from AI.

Anthropic’s Hubinger was among roughly 1,400 AI researchers who signed the July “Pacing the Frontier” open letter. The letter called on the U.S. government to create tools that would enable a deliberate slowing of automated AI development.

Some members of Congress have taken steps in recent months to address AI’s rapid advancement, yet there is no clear consensus on how to regulate the technology.

In July, Rep. Jay Obernolte (R‑Calif.) and Rep. Lori Trahan (D‑Mass.) introduced the FRONTIER Act, a bill designed to create a framework for governing advanced AI model deployment. Earlier this month, Sen. Bernie Sanders (I‑Vt.) and Rep. Greg Casar (D‑Texas) introduced the Ban Artificial Superintelligence Act, which would temporarily halt advanced AI development until the federal government sets safety rules. Both proposals have received mixed reactions.

“Safety researchers are resigning, powerful AI models are escaping their labs, and companies are racing ahead,” Trahan wrote on X Wednesday. “It’s long past time for Congress to step off the sidelines and act.”

Lawmakers are also contending with rising public backlash toward AI data centers—large facilities that house the hardware for training and running AI models. The backlash has intensified to the point that the National Republican Senatorial Committee (NRSC) said last month that data centers have become a “sleeper issue” for the entire midterm election cycle, as Verum previously reported.

Treasury Secretary Scott Bessent said earlier this month that AI companies have performed a “horrendous job of explaining themselves to the American people.”

“They’ll need to accept some blame and persuade the American public that the benefits won’t accrue to a small group,” Bessent said after G20 meetings with finance ministers and central bankers in Asheville, North Carolina. “That’s what they hear from me.”

Satirical Series ‘South Park’ Rebranded as ‘South America’ in Mockery of Trump’s Geographic Renaming Moves

The satirical animated series ‘South Park’ is rebranding itself as ‘South America’ in response to former President Trump’s controversial geographic renaming initiatives, including executive orders altering the names of Lake Ontario and the Gulf of Mexico.

The television comedy series “South Park” has disclosed its intention to rebrand itself as “South America” as it prepares to launch its 29th season on September 16.

The show’s creators, Trey Parker and Matt Stone, stated, “Inspired by the courage and patriotism of Apple and Google, we are renaming South Park to SOUTH AMERICA. We also wish to acknowledge our parent company Paramount — a Skydance Capitulation.”

Parker and Stone’s remarks follow U.S. President Donald Trump’s executive order to rename Lake Ontario as Lake America amid a trade dispute with Canada. Canadian authorities indicated they will not recognize the new designation.

Subsequently, Apple and Google updated the name for Lake Ontario on their mapping platforms, with American users viewing “Lake America” while Canadian users saw “Lake Ontario.”

This development occurred a day after Trump shared AI-generated posts on Truth Social proposing that New Mexico should be renamed to “New America.”

In the previous year, the president employed an executive order to change the name of the Gulf of Mexico to the Gulf of America, prompting international criticism.

“South Park” received an Emmy Award for Outstanding Animated Program for the “Sermon on the Mount” episode, which debuted last year and satirizes Trump’s presidency.

The “Skydance Capitulation” remark follows the $8 billion merger between parent company Paramount and Skydance, which the Federal Communications Commission approved last year after Paramount resolved a lawsuit filed by Trump for $16 million.

Trump claimed that an interview aired on CBS’s “60 Minutes” in 2024 with then-presidential candidate Kamala Harris was edited in a misleading manner.

Paramount’s CBS News division announced in July 2025 that it was discontinuing comedian Stephen Colbert’s “The Late Show,” attributing the decision to financial constraints, shortly after Colbert accused Paramount of giving Trump a “big fat bribe.” The final episode of the program was broadcast in May.

Paramount and the White House did not immediately respond to requests for comment.
