Human athletes demonstrate versatile and highly dynamic tennis skills to successfully conduct competitive rallies with a high-speed tennis ball. However, reproducing such behaviors on humanoid robots is difficult, partially due to the lack of perfect humanoid action data or human kinematic motion data in tennis scenarios as reference. In this work, we propose LATENT, a system that Learns Athletic humanoid TEnnis skills from imperfect human motioN daTa.

We believe we’re the first robotics company to demonstrate a robot peeling an apple with dual dexterous human-like hands. This breakthrough closes a key gap in robotics, achieving bimanual, contact-rich manipulation and moving far beyond the limits of simple grippers.

Today’s AI models (VLMs) are excellent at perception but struggle with action. Controlling high-degree-of-freedom hands for tasks like this is incredibly complex, and precise finger-level teleoperation is nearly impossible for humans. Our first step was a shared-autonomy system: rather than controlling every finger, the operator triggers pre-learned skills like a “rotate apple or tennis ball” primitive via a keyboard press or pedal. This makes scalable data collection and RL training possible.
How does the AI manage this? We created “MoDE-VLA” (Mixture of Dexterous Experts). It fuses vision, language, force, and touch data by using a team of specialist “experts,” making control in high-dimensional spaces stable and effective. The combination of these two innovations allows for seamless, contact-rich manipulation. The human provides high-level guidance, and the robot executes the complex in-hand coordination required.

Widely used Trivy scanner compromised in ongoing supply-chain attack

Hackers have compromised virtually all versions of Aqua Security’s widely used Trivy vulnerability scanner in an ongoing supply chain attack that could have wide-ranging consequences for developers and the organizations that use them.

Trivy maintainer Itay Shakury confirmed the compromise on Friday, following rumors and a thread, since deleted by the attackers, discussing the incident. The attack began in the early hours of Thursday. When it was done, the threat actor had used stolen credentials to force-push all but one of the trivy-action tags and seven setup-trivy tags to use malicious dependencies.

Assume your pipelines are compromised

A forced push is a git command that overrides a default safety mechanism that protects against overwriting existing commits. Trivy is a vulnerability scanner that developers use to detect vulnerabilities and inadvertently hardcoded authentication secrets in pipelines for developing and deploying software updates. The scanner has 33,200 stars on GitHub, a high rating that indicates it’s used widely.

IEEE Partners With Academia to Create Microcredential Programs

The rapid ascent of artificial intelligence and semiconductor manufacturing has created a paradox: Industries are booming yet they face a critical shortage of skilled workers. Demand for data center technicians, fabrication facility workers, and similar positions is growing. There aren’t enough candidates with the right skill sets to fill the in-demand jobs.

Although those technical roles are essential, they don’t always require a four-year degree—which has paved the way for skills-based microcredentials. By partnering with higher education institutions and training providers, industry leaders are helping to design targeted skills programs that quickly turn learners into job-ready technical professionals.

The new standard for skills validation

Because microcredentials are relatively new, consistency is key. Through its credentialing program, IEEE serves as a bridge between academia and industry. Developed and managed by IEEE Educational Activities, the program offers standardized credentials in collaboration with training organizations and universities seeking to provide skills-based qualifications outside formal degree programs. IEEE, as the world’s largest technical professional organization, has more than 30 years of experience offering industry-relevant credentials and expertise in global standardization.

IEEE is setting the benchmark for skills-based microcredentials by establishing a framework that includes assessment methods, qualifications for instructors and assessors, and criteria for skill levels.

A recent collaboration with the University of Southern California, in Los Angeles, for example, developed microcredentials for USC’s semiconductor cleanroom program. USC heads the CA Dreams microelectronics innovation hub.

“The IEEE framework allows us to rapidly prototype training programs and adapt on the fly in a way that building new university courses—much less degree programs—won’t allow.” —Adam Stieg

IEEE worked with USC to create standardized skills assessments and associated microcredentials so that industry hiring managers can recognize the newly developed skills. The microcredentials help people with or without four-year degrees join the semiconductor industry as cleanroom technicians or as engineers with cleanroom experience.

IEEE also has partnered with the California NanoSystems Institute at the University of California, Los Angeles, to create skills-based microcredentials for its cleanroom protocol and safety program.

Best practices for designing microcredentials

Based on IEEE’s work designing microcredentials with USC, UCLA, and other leading academic institutions, three best practices have emerged.

1. Align with industry needs before design.

Collaborate with industry prior to starting the design process. There isn’t a one-size-fits-all approach. Workforce needs vary based on industry sector, company size, and geography. Higher education institutions and training providers build relationships with companies and industry groups to create effective microcredential programs and methods of assessment.

2. Build for flexibility.

Traditional academic cycles can be slow, but technology moves fast. A flexible skills-based microcredentials framework allows programs to create or pivot as new breakthroughs occur.

“Setting up a credit-bearing course is not easy. And in a rapidly changing environment, you need to pivot quickly,” says Adam Stieg, research scientist and associate director at UCLA’s CNSI. “IEEE skills-based microcredentials are a flexible way to keep up our curriculum aligned with an evolving technology landscape.”

Stieg’s team worked with IEEE to build a framework to create microcredentials for its cleanroom protocol and safety program, ensuring it kept pace with the industry’s evolution.

“The IEEE framework allows us to rapidly prototype training programs and adapt on the fly,” he says, “in a way that building new university courses—much less degree programs—won’t allow.”

3. Implement a continuous-feedback loop.

Many of the technical roles companies are looking to fill in emerging fields such as AI, cybersecurity, and semiconductors are still being developed or are quickly evolving. The rapidly changing landscape requires continual communications and feedback among higher education, training providers, and industry.

“We struggle to have feedback loops through the education system to the industry and back again,” says Matt Francis, president and CEO of Ozark Integrated Circuits, in Fayetteville, Ark. Francis, who has served as IEEE Region 5 director, is an IEEE volunteer who supports workforce development for the semiconductor industry.

Creating consistent feedback loops is critical for generating consensus on the skills sets needed for microcredential programs, experts say, and it allows providers to update assessments as new tools and safety protocols enter the workplace.

“If we start thinking about having training frameworks used within companies that are essentially on some sort of standard and align with a microcredential, we can start to build consensus,” Francis says.

Getting started

Through its credentialing program, IEEE is helping higher education and industry work together to bridge the technical workforce skills gap. Contact its team to learn how IEEE skills-based microcredentials can help you fill your workforce pipeline.

Rising Attacks on Power Grids Push Utilities to Prepare

In the fictional nation of Beryllia, the 2026 World Chalice Games were set to begin as the country faced an unrelenting heat wave. The grid, already under strain from the circumstances, was dealt a further blow when a coordinated set of attacks including vandalism, drone, and ballistic attacks by an adversary, Crimsonia, crippled the grid’s physical infrastructure.

This scenario, inspired by the upcoming 2026 World Cup and the 2028 Olympic Games in Los Angeles, was an exercise in studying how utilities can prevent and mitigate, among other dangers, physical attacks on power grids. Called GridEx, the exercise was hosted by the Electricity Information Sharing and Analysis Center (E-ISAC) from 18 to 20 November, 2025, and was described in a report released on 2 March. GridEx has been held every two years since 2011.

“We know that threat actors look to exploit certain circumstances,” says Michael Ball, CEO of E-ISAC, which is a program of the North American Electric Reliability Corporation (NERC), about designing the Beryllia scenario. “The Chalice Games became a good example of how we could build a scenario around a threat actor.”

Physical attacks on the grid are rising in the U.S., and GridEx attendance was up in November as utilities grapple with how to prevent and mitigate attacks. Participation in the exercise was at its highest level since 2019, according to the new report. Given the number of organizations present, GridEx estimates that more than 28,000 individual players participated, including utility workers and government partners, an all-time high since the exercise began.

Rising Physical Threats to Power Grids

The U.S. and Canadian grids face growing security issues from physical threats, including vandalism, assault of utility workers, intrusion of property, and theft of components, like copper wiring. NERC’s 2025 E-ISAC end of year report cites more than 3,500 physical security breaches that calendar year, about 3 percent of which disrupted electricity. That’s up from 2,800 events cited in the 2023 report (3 percent of those also resulted in electricity disruptions). Yet despite a number of recent high-profile attacks in the U.S., physical attacks on the grid are happening worldwide.

“They’re not uniquely a U.S. thing,” says Danielle Russo, executive director of the Center for Grid Security at Securing America’s Future Energy, a nonpartisan organization focused on advancing national energy security. Russo says that while attacks are common in places like Ukraine, they’re not limited to wartime scenarios. “Other countries that are not experiencing direct conflict are experiencing increasing amounts of physical attacks on their energy infrastructure,” she says. Take Germany for example: On 3 January, an arson attack by left-wing activists in Berlin caused a five-day blackout impacting 45,000 households. That comes after a suspected arson attack on two pylons in September 2025 left 50,000 Berlin households without power. Some German officials cite domestic extremism and fears of Russian sabotage in recent years as reasons for heightened security concerns over critical infrastructure.

The uptick in attacks on the U.S. grid has been anchored by a number of incidents in recent years. In December 2025, an engineer in San Jose, California was sentenced to 10 years in prison for bombing electric transformers in 2022 and 2023. A Tennessee man was arrested in November 2024 for attempting to attack a Nashville substation using a drone armed with explosives. And in 2023, a neo-Nazi leader was among two arrested in a plot to attack five substations around Baltimore with firearms, part of an increasing trend in white supremacist groups planning to attack the U.S. energy sector.

“Since [E-ISAC] started publishing data back in 2016, we’ve seen a large and consistent increase in the number of reported physical security incidents per year,” says Michael Coe, the vice president of physical and cyber security programs at the American Public Power Association, a trade group that works with E-ISAC to plan GridEx. While not all data is publicly available, Coe says there’s been a “tenfold” increase over the past decade in the number of reported physical attacks on the grid.

Drone Attacks: A Grid Security Challenge

During the fictional World Chalice Games scenario, drone attacks destroyed Beryllia’s substation equipment, highlighting a threat that’s gained traction as more drones enter the airspace.

“The question we get all the time is, how do you tell if it’s a bad actor, or if it’s a 12-year-old kid that got the drone for their birthday?” says Erika Willis, the program manager for the substations team at the Electric Power Research Institute (EPRI).

One strategy to track and alert utilities to potential threats such as drones is called sensor fusion. The system includes a pan-tilt-zoom camera capable of 360-degree motion mounted on top of a tripod or pole with four installed radars. The radars combine with the camera for a dual system that can track drones even if they’re obstructed from view, says Willis. For instance, if a nearby drone flies behind a tree, hidden from the camera, the radars will still pick up on it. The technology is currently being tested at EPRI’s labs in Charlotte, North Carolina and Lenox, Massachusetts.

EPRI is also exploring how robotics and AI can improve security systems, Willis says. One approach involves integrating AI analysis into robotic technology already surveilling substation perimeters. Using AI can improve detection of break-ins and damage to fencing around substations, Willis says. “As opposed to a human having to go through 200 images of a fence, you can have the AI overlays do some of those algorithms…If the robot has done the inspection of the substation 100 times, it can then relay to you that there’s an anomaly,” Willis says.

Prisma Photonics deploys fiber sensing technology that uses reflected optical signals to detect perturbations from vehicles and other sources near underground fiber cable.Prisma Photonics

Already, a number of utilities in the U.S. are using AI integrations in their security and monitoring processes. That’s thanks in part to the Tel Aviv, Israel-based Prisma Photonics, a software company that launched in 2017 and has since deployed its fiber sensing technology across thousands of miles of transmission infrastructure in the U.S., Canada, Europe, and Israel. A file-cabinet-sized unit plugs into a substation and sends light pulses down existing fiber optic cables 30 miles in each direction. As the pulses travel down the cables, a tiny fraction of the light is reflected back to the substation unit. An AI model processes the results and can classify events based on patterns in the optical signal as a result of perturbations happening around the fiber cable.

“If we identify an event that we don’t have a classification for, and we get a feedback from a customer saying, ‘oh, this was a car crash,’ then we can classify that in the model to say this is actually what happened,” says Tiffany Menhorn, Prisma Photonics’ vice president of North America.

As preparations get underway for the ninth GridEx in 2027, Ball says participation in the exercises alone isn’t enough to bolster grid security. Instead, he wants utilities to take what they learn from the training and apply it in their own operations. “It’s the action of doing it, versus our statistic of saying, ‘here’s what our growth was.’ That growth should relate to the readiness and capability of the industry.”

I changed the tense on this because the subsequent sentences use past tense. It seemed weird to switch from present tense in the first sentence to past tense in the rest of the paragraph, but I could be mistaken.

Cloud service providers ask EU regulator to reinstate VMware partner program

A trade association of cloud service providers (CSPs) filed an antitrust complaint today with the European Union’s European Commission (EC) over Broadcom's shuttering of VMware’s CSP partner program this year.

Since Broadcom bought VMware, it has drastically cut the number of channel partners VMware works with, a shift that began with the elimination of VMware’s partner program. Broadcom replaced the program with an invite-only alternative that favors larger partners working with enterprise-sized clients rather than small-to-medium-sized businesses.

There are even fewer CSP partners working with VMware today. Broadcom introduced a requirement that CSP partners operate at least 3,500 cores, rendering hundreds of CSPs ineligible for partnership. Before Broadcom bought VMware, the virtualization company had over 4,000 CSP partners, per a February 2024 report from The Register. Today, VMware reportedly has 19 CSP partners in the US and about nine in the United Kingdom, The Register reported.

Nigerian Firms Embrace Kit-Based EV Assembly for Cost Savings

A growing number of Nigerian companies are turning to kit-based assembly to bring electric vehicles to market in Africa. Lagos-based Saglev Micromobility Nigeria recently partnered with Dongfeng Motor Corporation, in Wuhan, China, to assemble 18-seat electric passenger vans from imported kits.

Kit-based assembly allows Nigerian firms to reduce costs, create jobs, and develop local technical expertise—key steps toward expanding EV access. Fully assembled and imported EVs face high tariffs that put them out of reach for many African consumers, whereas kit-based approaches make electric mobility more affordable today. Saglev’s initiative reflects a broader trend: CIG Motors, NEV Electric, and regional players in Cote D’Ivoire, Ghana, and Kenya are also leveraging imported kits to build local EV ecosystems, signaling that parts of West Africa are intent on catching up with global electrification efforts.

Expanding the Local EV Ecosystem

CIG Motors operates a kit-assembly plant in Lagos producing vehicles from Chinese automakers GAC Motor and Wuling Motors. These vehicles include the Wuling Bingo, a compact five-door electric hatchback, and the Hongguang Mini EV Macaron, a microcar with roughly 200 kilometers of range aimed at ride-share operators looking for ultralow-cost urban transport. NEV Electric focuses on electric buses and three-wheelers for urban transit and last-mile delivery.

Saglev’s CEO, Olu Faleye, emphasizes that Nigeria’s EV transition addresses both practical economic needs in addition to environmental goals. Beyond passenger transport, electric vehicles could help reduce one of Nigeria’s persistent agricultural challenges: post-harvest spoilage. Nigeria loses an estimated 30–40 million tonnes of food annually because of weak logistics and limited refrigeration infrastructure, according to the Organization for Technology Advancement of Cold Chain in West Africa.

Electric vans, mini-trucks, and three-wheel cargo vehicles could help close this gap because their batteries can power refrigeration systems during transport without relying on costly diesel fuel. As EV adoption grows and charging infrastructure expands, temperature-controlled transport could become more affordable, reducing spoilage, improving farmer incomes, and helping stabilize food supplies, the organization says.

“I don’t believe that the promised land is making a fully built EV on the ground here.”
–Olu Faleye, Saglev CEO

Beyond Nigeria, Mombasa, Kenya–based Associated Vehicle Assemblers has begun assembling electric taxis and minibuses from imported kits, and Ghana’s government is spurring kit-car assembly there under its national Automotive Development Plan. In Ghana, assemblers benefit from import-duty exemptions on kits and equipment, corporate tax breaks, and access to industrial infrastructure. Saglev is already availing itself of those benefits, at its kit-assembly plant in Accra. The company says it also plans to expand its assembly operations to Cote D’Ivoire.

Infrastructure Challenges and Workarounds

Despite these signs that West Africa’s EV ecosystem is gaining traction, limited grid reliability and sparse public charging infrastructure remain major barriers to widespread EV adoption. Urban households in Nigeria experience roughly six or seven blackouts per week, each lasting about 12 hours, according to Nigeria’s National Bureau of Statistics. That’s more downtime each day than the average U.S. household experiences in a year. More than 40 percent of households rely on generators, which supply about 44 percent of residential electricity, according to research by Stears and Sterling Bank.

Many early EV adopters therefore charge vehicles using gasoline or diesel generators. Faleye notes that Nigerians have long relied on such workarounds and expects fossil fuels to remain part of the EV charging equation for the foreseeable future—at least until falling costs for solar panels and battery storage make cleaner charging viable.

He acknowledges that charging EVs using hydrocarbons is fraught from an environmental perspective, but he points out that the practice at least brings other benefits of EVs, including lower maintenance costs and the EVs’ synergies with refrigeration and transportation logistics. And he points to a 2020 peer-reviewed study in the journal Environmental and Climate Technologies that compared the overall efficiency of internal combustion vehicles and electric vehicles across the full well-to-wheel energy chain. The study’s conclusion: Even after accounting for conversion losses, generating electricity with a diesel or gasoline generator to power an electric vehicle can remain just as efficient overall as burning the same fuel directly in a vehicle’s internal combustion engine.

Scalable EV Adoption in Nigeria

The approach taken by Saglev and other Nigerian kit-car builders shows how local assembly can advance EV adoption even where infrastructure remains unreliable. By starting with kits, companies can deploy practical electric mobility solutions now while building the supply chains and technical expertise needed for more resource-intensive localized production.

Still, when asked whether Saglev plans to eventually move beyond kit assembly to independent design and manufacturing of EVs, Faleye calls such a move impractical.

“I don’t believe that the promised land is making a fully built EV on the ground here,” he says. “For me to do efficient vehicle manufacturing, I’d need a lot of robotics and 3D printing. That expense is unnecessary—it would just increase costs and make EVs more expensive.”

In a country where electricity can disappear for days, Nigeria’s kit-based EV strategy highlights a practical truth: incremental progress and ingenuity may matter more than perfect infrastructure. For Saglev, every kit-based vehicle rolling off the line is not just a van or bus—it’s a step toward an EV ecosystem that works for Nigeria’s realities today.
