Expanding on a long history of collaboration between KDDI and Nokia Bell Labs, the Japanese operator and the renowned communications research hub have entered a joint research agreement to explore new approaches for making 6G networks more energy efficient and resilient.
The research agreement is designed to help both organisations shape the direction of 6G research and bring practical innovations closer to real-world deployment. By combining KDDI’s real network data and operational insights with Nokia Bell Labs’ advanced energy consumption models and features and expertise in programmable network architectures, the companies believe they can jointly explore new approaches to energy efficiency and distributed core network design.
Principally, the research is being conducted in two key areas of 6G: mobile multiple input, multiple output (mMIMO) energy efficiency and distributed programmable core network services for 6G.
Within the former domain, the companies will be investigating techniques for reducing base station energy consumption while enhancing communication, specifically targeted at the proposed 6G spectrum. Looking at distributed programmable 6G core services, they are working on finding new mobile technologies that will ensure continuous communication during infrastructure failures and natural disasters.
Commenting on the partnership and its aims, Nokia Bell Labs core research president Peter Vetter said: “Tackling the inherent challenges in a new generation of networking requires close collaboration in the industry. Working side by side, KDDI Research and Nokia Bell Labs can advance the state of the art in networking thanks to different perspectives on the problems and possible solutions. Ultimately, the joint outcomes will make 6G a more resilient, efficient and intelligent technology.”

KDDI research president and CEO Satoshi Konishi added: “Through our strategic and close collaboration with Nokia Bell Labs, we aim to accelerate R&D initiatives and further strengthen the Power to Connect toward 6G. We strive to continuously deliver new value to our customers and make meaningful contributions to societal progress.”
5G collaboration in the Baltic region
As it was making its 6G deal with KDDI, Nokia revealed that it had also signed another operator-focused strategic agreement with Baltic and Nordic comms services provider and defence sector technological partner Latvijas Mobilais Telefons (LMT) to develop a tactical defence solution for the Baltic region.
The collaboration has the stated aim of creating a “unique” 5G tactical communications solution tailored for the currently tense region, integrating Nokia’s 5G radio technology with LMT’s proven defence solutions. LMT currently operates Europe’s first 5G military testbed at the Ādaži base, a key Nato site in Latvia. The work of the two companies is already said to have produced innovations such as a portable 5G tactical network using Nokia’s Banshee platform.
The collaboration, say the companies, will result in a high-capacity, secure, resilient tactical communications system specifically designed for dedicated use cases in the region, meeting the evolving needs of modern military operations and coalition forces.
Specifically, the integrated system will look to enable real-time data exchange among unmanned vehicles, sensors and military teams on the battlefield, enhancing situational awareness and ensuring secure interoperability to strengthen collective defence capabilities.
“Tactical defence systems harness the high speed, low latency and robust connectivity of 5G networks to enhance real-time operations on the battlefield. Our joint solution with LMT supports the modernisation of military capabilities, enabling faster decision-making, seamless communication and the integration of advanced technologies across tactical environments,” said Giuseppe Targia, head of space and defence at Nokia.

This will not be a banner year for the real estate app Zillow. “We describe the home market as bouncing along the bottom,” CEO Jeremy Wacksman said in our conversation this week. Last year was dismal for the real estate market, and he expects things to improve only marginally in 2026. (If January’s historic drop in home sales is indicative, that even is overoptimistic.) “The way to think about it is that there were 4.1 million existing homes sold last year—a normal market is 5.5 to 6 million,” Wacksman says. He hastens to add that Zillow itself is doing better than the real estate industry overall. Still, its valuation is a quarter of its high-water mark in 2021. A few hours after we spoke, Wacksman announced that Zillow’s earnings had increased last quarter. Nonetheless, Zillow’s stock price fell nearly 5 percent the next day.
Wacksman does see a bright spot—AI. Like every other company in the world, generative AI presents both an opportunity and a risk to Zillow’s business. Wacksman much prefers to dwell on the upside. “We think AI is actually an ingredient rather than a threat,” he said on the earnings call. “In the last couple years, the LLM revolution has really opened all of our eyes to what’s possible,” he tells me. Zillow is integrating AI into every aspect of its business, from the way it showcases houses to having agents automate its workflow. Wacksman marvels that with Gen AI, you can search for “homes near my kid’s new school, with a fenced-in yard, under $3,000 a month.” On the other hand, his customers might wind up making those same queries on chatbots operated by OpenAI and Google, and Wacksman must figure out how to make their next step a jump to Zillow.
In its 20-year history—Zillow celebrated the anniversary this week—the company has always used AI. Wacksman, who joined in 2009 and became CEO in 2024, notes that machine learning is the engine behind those “Zestimates” that gauge a home’s worth at any given moment. Zestimates became a viral sensation that helped make the app irresistible, and sites like Zillow Gone Wild—which is also a TV show on the HGTV network—have built a business around highlighting the most intriguing or bizarre listings.
More recently, Zillow has spent billions aggressively pursuing new technology. One ongoing effort is upleveling the presentation of homes for sale. A feature called SkyTour uses an AI technology called Gaussian Splatting to turn drone footage into a 3D rendering of the property. (I love typing the words “Gassian Splatting” and can’t believe an indie band hasn’t adopted it yet.) AI also powers a feature inside Zillow’s Showcase component called Virtual Staging, which supplies homes with furniture that doesn’t really exist. There is risky ground here: Once you abandon the authenticity of an actual photo, the question arises whether you’re actually seeing a trustworthy representation of the property. “It’s important that both buyer and seller understand the line between Virtual Staging and the reality of a photo,” says Wacksman. “A virtually staged image has to be clearly watermarked and disclosed.” He says he’s confident that licensed professionals will abide by rules, but as AI becomes dominant, “we have to evolve those rules,” he says.
Right now, Zillow estimates that only a single-digit percentage of its users take advantage of these exotic display features. Particularly disappointing is a foray called Zillow Immerse, which runs on the Apple Vision Pro. Upon rollout in February 2024, Zillow called it “the future of home tours.” Note that it doesn’t claim to be the near-future. “That platform hasn’t yet come to broad consumer prominence,” says Wacksman of Apple’s underperforming innovation. “I do think that VR and AR are going to come.”
Zillow is on more solid ground using AI to make its own workforce more productive. “It’s helping us do our job better,” says Wacksman, who adds that programmers are churning out more code, customer support tasks have been automated, and design teams have shortened timelines for implementing new products. As a result, he says, Zillow has been able to keep its headcount “relatively flat.” (Zillow did cut some jobs recently, but Wacksman says that involved “a handful of folks that were not meeting a performance bar.”)
Running with wet feet, in wet socks, in wet shoes is the perfect recipe for blisters. It’s also a fast track to low morale. Nothing dampens spirits quicker than soaked socks. On ultra runs, I always carry spares. And when faced with wet, or even snowy, mid-winter miles, the lure of weatherproof shoes is strong. Anything that can stem the soggy tide is worth a go, right?
This isn’t as simple an answer as it sounds. In the past, a lot of runners—that includes me—felt waterproof shoes came with too many trade-offs, like thicker, heavier uppers that change the feel of your shoes or a tendency to run hot and sweaty. In general, weatherproof shoes are less comfortable.
But waterproofing technology has evolved, and it might be time for a rethink. Winterized shoes can now be as light as the regular models, breathability is better, and the comfort levels have improved. Brands are also starting to add extra puddle protection to some of the most popular shoes. So it’s time to ask the questions again: Just how much difference does a bit of Gore-Tex really make? Are there still trade-offs for that extra protection? And is it really worth paying the premium?
I spoke to the waterproofing pros, an elite ultra runner who has braved brutal conditions, and some expert running shoe testers. Here’s everything you need to know about waterproof running shoes in 2026. Need more information?

How Do Waterproof Running Shoes Work?
On a basic level, waterproof shoes add extra barriers between your nice dry socks and the wet world outside. If you’re running through puddles deep enough to breach your heel collars, you’re still going to get wet feet. But waterproof shoes can protect against rain, wet grass, snow, and smaller puddles.
Gore-Tex is probably the most common waterproofing tech in footwear, but it’s not the only solution in town. Some brands have proprietary tech, or you might come across alternative systems like eVent and Sympatex. That GTX stamp is definitely the one you’re most likely to encounter, so here’s how GTX works.
The water resistance comes from a layered system that is composed of a durable water repellent (DWR) coating to the uppers with an internal membrane, along with other details like taped seams, more sealed uppers with tighter woven mesh, gusseted tongues, and higher, gaiter-style heel collars.
