AutoTL;DR

Researchers at the University of Hull recently unveiled a novel method for detecting AI-generated deepfake images by analyzing reflections in human eyes.

Adejumoke Owolabi, an MSc student at the University of Hull, headed the research under the guidance of Dr. Kevin Pimbblet, professor of astrophysics.

In some ways, the astronomy angle isn’t always necessary for this kind of deepfake detection because a quick glance at a pair of eyes in a photo can reveal reflection inconsistencies, which is something artists who paint portraits have to keep in mind.

They used the Gini coefficient, typically employed to measure light distribution in galaxy images, to assess the uniformity of reflections across eye pixels.

The approach also risks producing false positives, as even authentic photos can sometimes exhibit inconsistent eye reflections due to varied lighting conditions or post-processing techniques.

But analyzing eye reflections may still be a useful tool in a larger deepfake detection toolset that also considers other factors such as hair texture, anatomy, skin details, and background consistency.

In the biggest news of all, Rivian and Volkswagen announced a $5 billion joint venture that will co-develop core parts of the hardware and software platform to be used in cars from both automakers.

We love that because it aligns so beautifully with our mission: the ability to help accelerate putting highly compelling electric vehicles into the market, which will ultimately drive more demand.

A core objective of how we’ve structured the joint venture is that we don’t lose the velocity and the speed and the decisiveness and lack of bureaucracy that exists within our software function today.

Beyond just simplification of how we manage running over-the-air updates across so many different instances, it also gets us a lot of supply chain leverage in a way that we, Rivian, haven’t had in the past.

In fact, you can imagine the day of the announcement, I had a handful of phone calls from CEOs of big semiconductor suppliers, and they’re like, “Hey, we can work harder on pricing.” So, that was awesome.

So, taking away all those mechanical design studio packaging constraints that we had before, and then solving the biggest challenge, which was network architecture by this being that as a project, it’s just a very different type of relationship.

Police in Bangladesh have been granted “shoot-on-sight” orders and a nationwide curfew has been imposed as student-led protests continue to roil the country, leaving more than 100 people dead.

The curfew, imposed at midnight on Friday, was expected to last until Sunday morning as police tried to bring the swiftly deteriorating security situation under control, with military personnel patrolling the streets of the capital.

In extreme cases, police officers have been granted powers to open fire on those violating the curfew, confirmed Obaidul Quader, the general secretary of the ruling Awami League party.

They began earlier this month on university campuses as students protested against the reintroduction of civil service job quotas that they say are discriminatory and benefit the Awami League, led by Sheikh Hasina, the prime minister.

Pro-government student groups attacked protesters earlier this week and police were accused of instigating violence by firing teargas, rubber bullets and stun grenades at the demonstrators.

Representatives from both sides met late on Friday in an attempt to reach a resolution, with several student leaders demanding a complete reform of the quota system and for universities to be reopened.

There’s a big piece of paper in the San Francisco offices of Daylight Computer, with a list written in purple ink of all the kinds of devices the company hopes to one day make.

And as CEO Anjan Katta shows me around the office, the rest of the team is preparing for a launch party for its first device, a tablet called the DC-1, it’s clear he’s worried about how the world will respond to his big idea about the future.

Instead of modeling themselves off of purveyors of high tech like Apple or Samsung, Katta and Daylight seem to idolize companies like Patagonia, which both made good things and stands for something.

I like the speckled back and the clicky buttons, but I can’t stop noticing the very slightly misaligned ports or the fact that I can slide my fingernail between the display and the case and literally pry the thing apart.

Live Paper is actually designed to solve some of the weaknesses of E Ink — particularly its slow refresh rate and the ghosting that leaves faint impressions of stuff on the screen for too long.

He hasn’t solved all of them — the DC-1 doesn’t do color, which Katta tells me is technically possible but causes a bunch of other compromises — but the Daylight team has managed to make a 10.5-inch reflective LCD that is almost as easy on the eyes as E Ink and almost as responsive as a typical tablet screen.

Conspiracy theories about the shooting at a rally for Donald Trump began surfacing on X shortly after the news broke this afternoon, with the platform promoting topics including “#falseflag” and “staged” to users.

X owner Elon Musk has staunchly advocated for “free speech” on social media platforms — which can include misinformation like the above.

Bloomberg reported yesterday that Musk donated to a super PAC supporting Trump, giving a “sizable amount” to reelection efforts.

Musk has taken on increasingly conservative views in recent years, promoting the “great replacement” conspiracy theory and endorsing support for white pride.

Facebook’s search results primarily pointed to news outlets; the platform removed its trending topics section in 2018 over constant complaints about its curation.

Threads occasionally displayed conspiracy-related posts atop its trending topic for the incident, but they didn’t appear to surface consistently.

The attack, by a shooter who law enforcement officials say was then killed by the Secret Service, was the most serious attempt to assassinate a president or presidential candidate since Ronald Reagan was shot in 1981.

It comes amid a deeply polarized political atmosphere, just four months from the presidential elections and days before Trump is to be officially named the Republican nominee at his party’s convention.

The heavily armed tactical team travels everywhere with the president and major party nominees and is meant to confront any active threats while other agents focus on safeguarding and evacuating the person at the center of protection.

Law enforcement recovered an AR-style rifle at the scene, according to a third person familiar with the matter who spoke on condition of anonymity to discuss the ongoing investigation.

“Everybody went to their knees or their prone position, because we all knew, everyone becoming aware of the fact this was gunfire,” said Dave McCormick, the Republican candidate for U.S. Senate in Pennsylvania, who was sitting to Trump’s right on stage.

Two firefighters from nearby Steubenville, Ohio, who were at the rally told the AP that they helped people who appeared injured and heard bullets hitting broadcast speakers.

But before breaking up the band, the politically motivated and self-described “gay furry hackers” published a bunch of furious messages that SiegedSec claims were sent to them by Mike Howell, the executive director of the Heritage Foundation’s Oversight Project.

The feud began on July 9 after SiegedSec said it obtained usernames, passwords, logs and “other juicy info” belonging to the Heritage Foundation, and then leaked that private data online in response to the org producing and promoting Project 2025.

Project 2025 is a lengthy and fairly detailed blueprint that outlines how a future conservative president – such as, say, Donald Trump should he win the election again – could overhaul the federal government and public policy to enact a far-Right agenda and give huge powers to the executive branch.

And ultimately, it seeks to expand the executive branch’s power, ensure that federal agencies and their leaders and rank-and-file fall heavily in line with the president’s agenda and “push back against woke policies in corporate America” [PDF].

SiegedSec, whose previous targets have included America’s biggest nuclear power lab’s computer systems and NATO (on multiple occasions), said it took issue with Project 2025’s “authoritarian Christian nationalist plan to reform the United States government.”

From there the messages said to have been sent from Howell become increasingly dark, lecturing the crew on beastiality and how it’s a “weird sin,” calling them perverts," and then telling vio “you won’t be able to wear a furry tiger costume when you’re getting pounded in the ass in the federal prison I put you in next year.”

Palestinians calling home to Gaza on Skype have had their digital lives destroyed, after Microsoft closed their email accounts without warning.

BBC News has spoken to 20 Palestinians living abroad who say Microsoft, which owns the voice and video chat app, kicked them out of their accounts.

The Gazans say they have no links to Hamas - designated as a terrorist organisation by some Western countries, including the US, where Microsoft is headquartered - and accuse the technology giant, the most valuable company in the world, of persecuting them unfairly.

Salah Elsadi is living in the US and, like many Palestinians abroad, was using Skype to call his wife, children and parents on their mobile phones in Gaza.The internet is frequently disrupted or switched off because of the Israeli military campaign - and standard international calls are very expensive.

With a paid Skype subscription, it is possible to call mobiles in Gaza cheaply - and while the internet is down - so it has become a lifeline to many Palestinians.

But many of those BBC News has spoken to say they have tried many times and are receiving the same blanket response.One, Khalid Obaied, has lost faith with Microsoft.

In addition to probation, the teens will also be required to attend classes on gender and equality, as well as on the “responsible use of information and communication technologies,” a press release from the Juvenile Court of Badajoz said.

In addition to mental health impacts, victims have reported losing trust in classmates who targeted them and wanting to switch schools to avoid further contact with harassers.

Minors targeting classmates may not realize exactly how far images can potentially spread when generating fake child sex abuse materials (CSAM); they could even end up on the dark web.

An investigation by the United Kingdom-based Internet Watch Foundation (IWF) last year reported that “20,254 AI-generated images were found to have been posted to one dark web CSAM forum in a one-month period,” with more than half determined most likely to be criminal.

While lawmakers struggle to apply existing protections against CSAM to AI-generated images or to update laws to explicitly prosecute the offense, other more drastic solutions to prevent the harmful spread of deepfakes have been proposed.

Ars could not immediately reach Meta for comment on efforts to combat the proliferation of AI-generated CSAM on WhatsApp, the private messaging app that was used to share fake images in Spain.

In an interview with US media ahead of the summit, NATO Secretary General Jens Stoltenberg described China as “the main enabler of Russia’s war of aggression against Ukraine.”

According to the US assessment, China is the top supplier of machine tools, microelectronics, and nitrocellulose — critical to making munitions and rocket propellers — and other dual-use items that Moscow uses to ramp up its defense industrial base.

In June, South Korean National Security Advisor Chang Ho-jin told reporters Seoul will review the possibility of supplying weapons to Ukraine, after the leaders of North Korea and Russia signed a pact pledging mutual defense in the event of war.

NATO has collaborated with partners in the Indo-Pacific since the early 2000s, but Russia’s war against Ukraine and security challenges posed by China have led to a deeper engagement.

Ahead of the meeting, NATO chief Stoltenberg said the alliance and its Indo-Pacific partners “will build on our practical cooperation with flagship projects on Ukraine, cyber, and new technologies.”

Last year, France blocked a NATO plan to open a liaison office in Japan, insisting the alliance is geographically confined to the North Atlantic.

Microsoft is planning to hike its Xbox Game Pass Ultimate pricing again in September, alongside launching a new “standard” subscription that doesn’t include day-one access to first-party Xbox games.

The Xbox maker has started emailing Xbox Game Pass Ultimate subscribers warning of a price increase to $19.99 a month that starts on September 12th, a $3 increase over the current $16.99 a month pricing.

PC Game Pass subscribers will also see a price hike in September, with the service moving from $9.99 to $11.99 per month and maintaining access to day-one titles.

The price increases will largely affect Ultimate subscribers who make up the vast majority of Game Pass subscribers and come just over a year after the last Game Pass price hikes raised rates by $1–$2 per month.

Alongside the Ultimate and PC Game Pass price hikes, Microsoft will also offer a new option of an Xbox Game Pass Standard subscription without day-one titles that will be priced at $14.99 per month for new users to the service.

I revealed in May that Microsoft was considering raising Xbox Game Pass Ultimate pricing again, amid a debate around adding Call of Duty to the service.

A bunch of eighth graders in a “wealthy Philadelphia suburb” recently targeted teachers with an extreme online harassment campaign that The New York Times reported was “the first known group TikTok attack of its kind by middle schoolers on their teachers in the United States.”

According to The Times, the Great Valley Middle School students created at least 22 fake accounts impersonating about 20 teachers in offensive ways.

“I applaud the vast number of our students who have had the courage to come forward and report this behavior,” Souders said, urging parents to “please take the time to engage your child in a conversation about the responsible use of social media and encourage them to report any instances of online impersonation or cyberbullying.”

Following The Times’ reporting, the superintendent of the Great Valley School District (GVSD), Daniel Goffredo, posted a message to the community describing the impact on teachers as “profound.”

Instead, the middle school “briefly suspended several students,” teachers told The Times, and held an eighth-grade assembly raising awareness of harms of cyberbullying, inviting parents to join.

“I reiterate my disappointment and sadness that our students’ behavior has caused such duress for our staff,” Goffredo’s message to the community said.

The research, from scientists at the Johns Hopkins University in the US, suggests that the atmosphere of the planet HD 189733 b, a Jupiter-sized gas giant, has trace amounts of hydrogen sulphide.

At only 64 light-years from Earth, HD 189733 b is the nearest “hot Jupiter” astronomers can observe passing in front of its star.

The planet also has extremely high temperatures of about 927C and is known for vicious weather, including raining glass that blows sideways on winds of 5,000mph.

Guangwei Fu, an astrophysicist at Johns Hopkins University, said: "Hydrogen sulphide is a major molecule that we didn’t know was there.
