arXiv:2606.05354v1 Announce Type: new Abstract: Retinal blood vessel segmentation plays a vital role in the early detection of diabetic retinopathy and glaucoma. While recent deep learning models have achieved great segmentation accuracy, they typically require heavy computational resources, making real-world deployment on edge devices difficult. In this paper, we propose LightVesselNet, an efficient neural network designed for retinal vessel segmentation in a resource-constrained environment. Despite containing only 75K parameters, LightVesselNet performs competitively with much larger models. The network employs a compact encoder decoder architecture enhanced with channel and spatial attention mechanisms, a multi-scale feature aggregation module at the bottleneck, and a subpixel upsampling strategy in the decoder. A dedicated edge residual connection preserves fine vessel detail throughout decoding. Extensive experiments on five publicly available datasets: DRIVE, STARE, CHASEDB1, FIVES, and HRF, yield sensitivity scores of 0.8189, 0.8499, 0.8640, 0.8634, 0.8096, and Dice coefficients of 0.8070, 0.8072, 0.8181, 0.8649, and 0.7686, respectively. LightVesselNet shows improved efficiency (Performance vs Parameter or GFlops) compared to State-of-the-Art models. Cross-dataset evaluation confirms the model's generalisation capability. Overall, LightVesselNet is a strong candidate for deployment in low-resource clinical settings and mobile screening tools.

arXiv:2606.05347v1 Announce Type: new Abstract: Every new clinical imaging device creates a domain shift where dense gland masks are expensive yet cheap clinical signals -- eyelid outlines, Pult grades, morphometric ratios -- are routinely recorded. We present TopoPult-SSL, a two-stage framework for cross-device meibomian gland segmentation. Stage 1 adapts a source-trained model without target gland masks in the training loss, using four weak-prior anchors driven by target eyelid masks and clinical metadata only. Stage 2, when target gland masks are available, distils complementary Stage-1 teachers into a single compact student via supervised self-distillation. We develop and validate the technique on the public MGD-1k to CAMG research benchmark (1,000 to 100 images, different device), where the distilled model achieves Dice 0.716+/-0.006 (best 0.726), surpassing UA-MT (0.710) and the ensemble teacher (0.720) -- with a single pass. The gland-mask-free Stage-1 variant reaches Precision 0.694 vs. 0.30-0.34 for SAM/MedSAM (p<0.001), enabling deployment without dense gland contouring. Code and reproducibility scripts are released.

AI at the World Cup: smarter tactics, healthy players, safer crowds – but new risks

By Paul Salmon, Professor of Human Factors, University of the Sunshine Coast

With 48 teams and 104 games across 16 host cities and three countries (the United States, Canada and Mexico), this year’s FIFA World Cup is projected to be the biggest sporting event ever in terms of attendance, revenue and global viewership. It also promises to be the most technologically advanced, and artificial intelligence (AI) in particular will touch almost all aspects of the tournament. This reflects a growing use of AI in soccer and across elite sport, with tools being applied not only to optimise athlete performance but also enhance match officiating, event security and fan experience. Let’s look at how AI will be used in the World Cup, who may benefit and what risks could emerge. We tested the new World Cup ball – this is what you need to know about how it will fly, dip and swerve How it will be used on the pitch In our review of AI use in soccer we found various ways it can assist on the pitch: tools to support player, team and match evaluation forecasting of match outcomes and in-game events (such as expected goals and assists, corners, passes, opposition tactics) monitoring athlete workload injury prediction and detection talent scouting. At the World Cup, coaches will use AI alongside more conventional data to inform how they approach each game, including what opposition strengths they need to negate and what weaknesses they can exploit. Similarly, high performance staff will use AI to monitor player health and wellbeing, and forecast potential injuries. The dreaded penalty shoot-out is one area where AI will have a direct influence. Teams will use AI to synthesise historical data to provide insights on goalkeepers and penalty takers’ likely strategies. A key benefit is the speed at which these analyses can be undertaken. What used to take days of old-fashioned human legwork can now be done in hours, even for entire squads. Should a game go to a shootout, AI could very likely influence the winning kick or save. What about referees? Match officials will also be supported by AI. While semi-automated offside technology was introduced in the 2022 World Cup, it will be enhanced through the addition of AI-enabled 3D avatars of every player. The aim is to improve referees’ decision accuracy through the use of more precise body dimensions of the players involved. The avatars will also be used to provide more engaging content when Video Assistant Referee (VAR) decisions are shown to fans. Rather than seeing only generic figures, fans will now see realistic avatars incorporating players’ faces, kit and even their hairstyle. Another use in match officiating will be referee view technology, which uses body cameras to capture in-game footage from the referee perspective. AI will be used to stabilise images, with the emphasis on enhancing the fans’ immersive experience. What about off the field? Crowd management and logistics are other areas where AI will be deployed. FIFA has built an “Intelligence Command Centre” – which will connect data across matches, venues and broadcasters – as well as digital twin models of stadiums to monitor and forecast crowd behaviour. This will aim to ensure crowd-related issues such as bottlenecks are controlled. Are there any risks? While there are many benefits, a broad spectrum of risks will need to be managed. Key concerns with AI tools are substandard outputs, and loss of skills and meaningful work for humans. To combat this, teams should ensure AI is only used to support human decision making, not replace it. Data privacy and security will be key concerns, with the possibility of confidential or sensitive information being leaked or accessed by unauthorised or malicious actors. The use of AI in areas such as security and crowd management could also provide the opportunity for highly disruptive cyber attacks. Equality could be an issue: teams with more financial power may have an advantage through more sophisticated tools. In an attempt to level the playing field, FIFA has introduced Football AI Pro, an AI tool available to all teams. This soccer-specific large language model supports both pre- and post-match analysis and provides access to more than 2,000 metrics. The aim is to ensure all nations have access to at least some level of AI support. It remains to be seen which nations actually use it. Another potential adverse outcome is tactical homogenisation, where games become predictable because every team follows the same AI-generated game plan. Sadly, AI will likely be deployed for nefarious purposes, for example as part of ticketing scams through AI-generated images, deepfakes, websites and phishing emails. Fans should take care at all times. AI will be everywhere AI is fast becoming a key component of high performance sport. It will be leveraged throughout the tournament to support preparation, performance and recovery. While it could increase the gap between larger and smaller nations, it might also give smaller nations a new edge. So could 2026 be the year in which AI genuinely contributes to a World Cup win? We won’t see an AI agent scoring a goal, or a robot coach calling the shots (at least not yet) but there is no doubt the winner of the tournament will have relied on AI along the way. In terms of who that will be – well, we could always ask AI.

When you ship code faster than engineers can read it, in domains where nobody has full context, you are making withdrawals from a trust account that took years to build.

Australia now has access to Anthropic’s Claude Mythos. It may improve cyber safety – but not for everyone

By Andrew Cullen, Senior Research Fellow, School of Computing and Information Systems, The University of Melbourne

Google DeepMind Artificial intelligence (AI) giant Anthropic has expanded access to a highly advanced model deemed too dangerous for public release, including Australia in the select handful of users. The large language model, known as Claude Mythos, is now being rolled out to an additional 150 organisations across 15 countries, including the Australian government and several local businesses, as part of Project Glasswing. In an era where large-scale AI launches are happening on a day-by-day basis, this limited, gradual release may seem particularly surprising. But Mythos is not like most other AI systems. Instead it’s an automated tool for assessing software to find critical bugs and vulnerabilities. This managed release is deliberate, as the discovery of vulnerabilities in computer systems is useful for those who want to defend them and those who want to hack them. However, the real nature of the impact of AI systems on cybersecurity is significantly more complex. Finding hundreds of severe vulnerabilities Under initial testing, Mythos has been able to identify multiple new high-risk vulnerabilities. Left unfixed, such flaws allow attackers to easily steal data or induce system crashes. While these reports are promising, the raw data needs context. Of the 23,000 vulnerabilities flagged by Mythos, only 6,200 were estimated as high-risk by Mythos. However AI isn’t perfect, as human experts could only validate two in every three of these vulnerabilities as high-risk. Even still, the nature and severity of identified vulnerabilities has led developers to say that with Mythos “defenders finally have a chance to win, decisively”. And winning this battle is extremely valuable. Over the last few years, Australians have repeatedly been the victims of costly cybersecurity incidents, including Optus, Medibank Private, the Melbourne International Film Festival, and Canvas. This barrage of attacks likely explain why the Australian Signals Directorate welcomed Australia’s inclusion in Anthropic’s Project Glasswing. While this AI-driven security offers huge potential benefits, the government so far has been tight-lipped on the specifics of how Mythos will actually be used. Dangerous in the wrong hands While discovering vulnerabilities is useful, defenders need to be able to respond to them. This is problematic when tools like Mythos produce large numbers of false reports, which have the potential to overwhelm unprepared cybersecurity teams. More concerningly, while access to Mythos is currently tightly controlled, it will not be long until similar tools are available to help support hackers. And it’s not just the vulnerabilities that AI can discover that pose risks. AI systems more broadly are incredibly vulnerable to being tricked or exploited, with highly damaging consequences. Just this week, hackers used Meta’s AI powered chatbot to gain access to high-profile Instagram accounts, including Barack Obama’s. They did so by tricking AI chatbots into changing account details. And, even after Instagram announced it fixed the issue, within hours there were reports of further accounts being compromised. A similar attack known as Echoleak last year revealed how tying Microsoft Copilot to email accounts could introduce significant risks. This was made possible by sending emails to accounts monitored by Copilot’s AI. These emails tricked the AI into leaking large amounts of private and confidential information, without the email ever needing to be opened by a human. No longer do we live in a world where hackers need to convince users to click a malicious link, if they can instead convince the AI that reads emails to act dangerously. Both Echoleak and the Instagram hacks underscore the risks we face as more and more organisations tie their critical functions to AI systems that are difficult to audit, and easy to exploit – even by just being persuasive. A new balance point All of this suggests the current cybersecurity landscape might be shifting to a new balance point, where defenders and hackers race to develop and exploit powerful AI tools. Tools like Mythos aren’t a silver bullet. While they provide defenders with an additional set of eyes on where to look, it still will require expertise to work out what is real, and what isn’t. But the advent of the AI era has already fundamentally changed the risks associated with poor cybersecurity practices. Every day a user or service provider delays a software update on one of their devices is a day where a vulnerability can be exploited. For cybersecurity teams, ensuring compliance is already a difficult enough process that will only get worse when the speed of vulnerability discovery increases. While they are high value targets for hackers, large organisations will likely remain safe, as they will have the resources to access and deploy tools like Mythos. But smaller, less resourced companies will likely not have the capacity to access these tools – or to react to the upcoming tsunami of cybersecurity updates. And if they fall behind on these updates, these smaller companies will likely find themselves at far more risk than they ever have been before. The cybersecurity divide between those with and without resources will only grow. Bridging this gap is not just an IT challenge – it’s a public safety concern that will affect us all.

Mike Coppola/Getty Images; Kyle Grillot/Bloomberg via Getty Images; Kyle Grillot/Bloomberg via Getty Images Silicon Valley elites like Sam Altman and Palmer Luckey faced off in a new online game show. The show had the tech leaders play a Mafia, a murder-mystery game of deception. Founders Fund, which launched the show, said the game has been popular in Silicon Valley for years. Twelve "tech legends" walk into a bar and start getting picked off one by one — who would you trust to suss out the killer? You can get a glimpse into that scenario thanks to a new show that gathered a group of Silicon Valley elite — including OpenAI founder Sam Altman, Anduril founder Palmer Luckey, and biohacker Bryan Johnson — to play Mafia, a murder-mystery game of deception. The show, which launched Thursday on YouTube and X, is from Founders Fund, the San Francisco-based venture capital firm co-founded by Peter Thiel. For viewers unfamiliar with Mafia, the purpose of the game is "to deceive and to detect deception," the show explains, adding, "For years, everyone in Silicon Valley has played." The game involves each player being randomly assigned a role, one of which is mafia. The mafia's goal is to kill off the rest of the players, while everyone else is trying to identify and kill off the mafia. The first episode was filmed at Tosca Cafe, an iconic San Francisco bar and restaurant that served as the location of the famous PayPal Mafia photo published in Fortune in 2007. The group of 12 players included: Altman; Luckey; Johnson; biohacker Josie Zayner; Wait But Why writer Tim Urban; professional poker player Liv Boeree; AI policy expert Ryan Beiermeister; Figma founder Dylan Field; Signal founder Moxie Marlinspike; angel investor Cyan Banister; Flexport founder Ryan Petersen; and Founders Fund partner Trae Stephens. We won't give any spoilers, but the game played out over a 33-minute episode in which accusations were thrown left and right. Luckey was quick to make jokes during the game, which made him a target to some. Some players joked about how others' real-world jobs could influence their role in the game. "Whatever Bryan says we should go with because he can't die," Stephens said of Johnson, who founded the app Don't Die and is famous for his quest to conquer aging. There were also some accusations thrown around between Altman and Beiermeister, who, according to The Wall Street Journal, was fired from OpenAI in January. Mike Solana, the CMO of Founders Fund and host of the game, said in an X post that the next two episodes of the show will be released on Thursdays over the next couple of weeks. The show is the latest example of Silicon Valley embracing new media ventures, with one of the most prominent being OpenAI's acquisition of the tech talk show TBPN.

Google CEO Sundar Pichai. Sergei GAPON / AFP via Getty Images Google is laying off some employees across its vast Cloud division. One elite cybersecurity unit, the Threat Intelligence Group, was hit with cuts yesterday. Tech companies across Silicon Valley are trimming their workforces as they pour billions into AI. Google is the latest Big Tech company to do layoffs this year. Employees working at Google Cloud have been hit by cuts over the last two weeks, two people familiar with the matter told Business Insider. One team, Google's Threat Intelligence Group, which is one of Google's top security units and regularly publishes research about hackers, was impacted yesterday, the people said. Some employees have been posting about the layoffs on LinkedIn. The cuts were not limited to that unit, affecting others at Mandiant — a cybersecurity company bought by Google in 2022 — and within Google Cloud, the people added. It's unclear exactly how many people were impacted and why the cuts are happening now. In one instance, Google cited the need to reinvest in growth areas, such as AI, to justify the move, one of the people said. "We regularly evaluate our internal structures to ensure we are best positioned to meet the evolving demands of our customers and the industry," a Google spokesperson told Business Insider. The cuts are just the latest to hit Big Tech as companies pour billions into AI. Meta laid off 10% of its staff last month, while others like Coinbase and Block used AI to justify big cuts earlier this year. Cybersecurity has also been affected: Cloudflare laid off more than 1,100 employees earlier last month as it prepares for the "agentic AI era." Last year, Google Cloud quietly let go of some staff, mostly in user experience roles, Business Insider reported. Have a tip?
