Drones paired with AI could help search‑and‑rescue teams find missing persons faster
AI-powered drones equipped with thermal and infrared imaging are transforming search-and-rescue operations, enabling teams to locate missing persons faster and assess their condition—including signs of injury, consciousness, or life-threatening temperature changes—in real time.

A combination of infrared imaging, thermal imaging and color cameras on an uncrewed drone, along with an AI system to interpret the data, can help emergency responders and search-and-rescue teams locate, identify and track people who have gone missing in the wilderness. The experimental system helps responders pinpoint where a missing person is and determine whether they are hurt or even alive.
People who get lost or hurt while exploring nature can become stranded for days. Rescue teams often use drones to look for the person or signs of their whereabouts. The small drone my colleagues and I built at my lab at Kennesaw State University flies autonomously using a grid search pattern. It sends live video and images to a ground station operated by the rescue team.
When the AI system finds a person, it analyzes images to determine whether the individual is upright or lying on the ground. It segments parts of the person’s body, identifying the person’s head and the body’s position. It then zeroes in on the forehead. It extracts forehead temperature readings, pixel by pixel, from the imaging data to estimate forehead temperature. We have two papers detailing these findings accepted for the American Institute of Aeronautics and Astronautics Aviation Forum 2026 conference.
Our AI model then assesses whether the person is conscious or unconscious and identifies abnormal temperatures that could indicate heat stress, hypothermia or other physical complications, or death – all vital information for a search-and-rescue team.
In field trials we have conducted, the system has provided consistent temperature readings of the heads of volunteers from our research team who have walked out into a variety of environments, under different conditions.
Why it matters
It is critical to get accurate and timely information on the whereabouts of a missing person. The likelihood that the person will survive decreases steeply as time passes.
An AI-enhanced drone can make search-and-rescue operations significantly more efficient than sending teams of people out into the environment to search on foot, especially in poor weather conditions or under thick foliage. Rescuers who know whether a person is conscious or unconscious can also better gear up for what they need to do to retrieve the person and administer aid. Our technology could save lives.
What other research is being done
Search-and-rescue personnel use various kinds of drones, but the machines often lack the ability to positively identify humans, especially under thick foliage, in bad weather or when the person is lying down or unconscious. The AI-based technology we have developed overcomes those challenges.
Better sensors that are very lightweight, that can function at night or in rain, and can see more clearly through thick foliage could further improve our drone and drones used by others. Researchers are devising AI-powered sound recognition for detecting screams for help, advanced thermal imaging for better nighttime vision and autonomous drones that could act as first responders.
Also under development are drones that can carry heavy payloads, such as flotation devices, fly for up to 14 hours or perform real-time mapping of the ground below.
What’s next
One of our next steps is to have multiple drones fly together and autonomously coordinate search-and-rescue operations among themselves. This will allow the technology to cover a much larger area, perhaps hundreds of square miles.
We are also designing a large drone that can carry up to 110 pounds (50 kilograms) of payload and stay aloft for an hour.
The Research Brief is a short take on interesting academic work.

CropX Technologies has launched CropX Vision, a new AI-powered vineyard monitoring solution designed to help growers measure vine water stress using a single canopy image.
The new tool uses computer vision and agronomic modeling to estimate leaf water potential from a smartphone photo, giving growers and agronomists a faster and more scalable way to assess plant stress across entire vineyard blocks. The company says the goal is to support better irrigation decisions throughout the growing season.
CropX Vision is available globally on both iOS and Android. The platform is also integrated into the broader CropX application, allowing users to combine canopy-based stress insights with other agronomic data in one place.
According to CropX, the technology offers an in-season alternative to traditional pressure chamber measurements, which can be more time-consuming and limited in sampling range. Instead of relying on specialized equipment, growers can capture a single image in the field and receive plant-level water stress insights.
The product builds on technology originally developed by Tule Technologies, a California-based precision irrigation company acquired by CropX in 2023. Tule’s canopy sensing technology has already been used in California vineyards, and CropX is now expanding that capability to growers worldwide.
CropX says the global release reflects its continued focus on data-driven tools that help growers improve productivity while managing water more efficiently.
CropX Vision is now available for download via the app stores:
- iOS: https://apps.apple.com/nl/app/cropx-vision/id6756921607?l=en-GB
- Android: https://play.google.com/store/apps/details?id=com.cropx.cropx_vision&pcampaignid=web_share

Stay Protected from Cyberattacks: Simple Safeguards to Reduce Cyber Intrusions and Real-World Losses
Be aware of Cyberattacks: Connected homes are becoming the norm with millions of Americans relying on Wi-Fi networks, mobile apps and smart devices to manage everything from door locks to thermostats. As convenience increases, so does exposure, and basic cybersecurity practices can help reduce both digital and physical risks.
Stay Protected from Cyberattacks: Simple Safeguards to Reduce Cyber Intrusions and Real-World Losses
(Feature Impact) Connected homes are becoming the norm with millions of Americans relying on Wi-Fi networks, mobile apps and smart devices to manage everything from door locks to thermostats.
As convenience increases, so does exposure, and the experts at multiple-line insurance carrier Mercury Insurance are reminding homeowners that basic cybersecurity practices can help reduce both their digital and physical risks.
“Smart-home technology is incredibly useful, but it also expands the number of entry points into your home – not just digitally, but physically,” said Dustin Howard, head of info security at Mercury Insurance. “The good news is that many of the most effective protections are simple, proactive steps that homeowners can take today.”
Smart-home adoption continues to accelerate with recent studies showing roughly 70% of U.S. households now use at least one connected device. From video doorbells to smart garage doors, these tools provide visibility and control, but if not properly secured, they can also create vulnerabilities that bad actors may exploit.
Consider these cybersecurity best practices for connected homes:
- Secure your Wi-Fi network: Use strong, unique passwords – at least 14-16 characters with a mixture of letters, numbers and symbols – and enable WPA3 encryption when available to prevent unauthorized access. Also turn on your router’s built-in firewall and disable Wi-Fi protected setup.
- Update devices regularly: Firmware and software updates often include critical security patches that close known vulnerabilities. Turn on automatic updates for operating systems, applications, browsers and smart home devices such as thermostats and cameras. If devices are no longer able to update, it may be time to replace them to avoid compromising security.
- Enable multi-factor authentication (MFA): Adding a second layer of verification significantly reduces the risk of unauthorized account access. Enable MFA for email accounts, banking and financial apps, cloud storage and social media accounts, and use an authenticator app for confirmation rather than receiving a code via text or email.
- Segment your network: Consider placing smart-home devices, including televisions, security cameras and speakers, on a separate network from personal devices like laptops and phones. Also create a guest network for visitors to use to help further protect your main network.
- Change default settings: Many devices come with default usernames and passwords that are widely known and easily exploited. Change the defaults on your router as well as login credentials for any new devices, making admin accounts more difficult to target.
- Monitor device activity: Regularly review connected devices and remove any that are unfamiliar or no longer in use. If your router supports it, enable notifications for new device connections for real-time visibility.
“As homes become more connected, cybersecurity becomes a core part of overall home protection,” Howard said. “It’s not just about protecting your data – it’s about protecting your property, your privacy and your peace of mind.”
With smart-home technology expected to continue expanding, homeowners should treat cybersecurity as a routine part of home maintenance – just like checking smoke detectors or locking doors – to stay ahead of evolving risks.

Nissan’s New Strategy: Innovation Meets Consolidation in a Changing Auto Market
Nissan’s New Strategy: Nissan is reshaping its lineup with fewer models, more hybrid technology, and smarter vehicles. Here’s what’s staying, what’s changing, and what it means for drivers.
Nissan’s New Strategy
As the global auto industry pivots toward electrification and smarter technology, Nissan is taking a more measured approach—introducing new innovations while trimming its lineup to focus on core models that drive sales and long-term value.
🚗 A Leaner, More Focused Nissan
In recent years, Nissan has begun reshaping its global strategy, reducing the total number of models while strengthening key vehicles across major segments. The goal is clear: prioritize profitability, streamline production, and invest in technology where it matters most.
Rather than flooding the market with new nameplates, Nissan is concentrating on a smaller, more competitive lineup—particularly in high-demand categories like SUVs and crossovers.
🔋 Innovation Where It Counts
Hybrid Technology Takes Center Stage
One of Nissan’s most important developments is its e-POWER hybrid system, which is set to debut more broadly in the U.S., particularly in the next-generation Nissan Rogue.
Unlike traditional hybrids, e-POWER uses a gasoline engine solely to generate electricity, while the wheels are driven by an electric motor. The result is a driving experience that feels closer to an EV—without requiring a charging station.
This technology reflects a growing industry reality: while electric vehicles are expanding, hybrids are emerging as a practical bridge for many consumers.
EV Evolution, Not Explosion
Nissan isn’t abandoning electric vehicles—it’s refining its approach.
The iconic Nissan LEAF is expected to return in a redesigned, crossover-style format, aimed at improving range, comfort, and mainstream appeal. However, Nissan is avoiding an aggressive all-electric push in favor of a balanced portfolio that includes gas, hybrid, and EV options.
Smarter Vehicles Through AI
Another key pillar of Nissan’s future is AI-assisted driving technology. The company plans to integrate advanced driver assistance and semi-autonomous features into a majority of its vehicles over the next several years.
These systems are designed to enhance:
- Safety
- Driver awareness
- In-car connectivity
While less visible than a new engine or redesign, this shift could become one of Nissan’s most impactful long-term innovations.
🚙 The Core Lineup: What’s Staying
Nissan’s future lineup is built around a group of proven, high-demand models that continue to evolve with new technology and features.
SUVs and Crossovers (The Backbone)
- Nissan Kicks – Entry-level, affordable, and recently redesigned
- Nissan Rogue – The brand’s best-seller and innovation leader
- Nissan Pathfinder – Family-focused with growing tech upgrades
- Nissan Armada – Large SUV with premium and performance appeal
These vehicles form a complete SUV ladder, covering nearly every price point and lifestyle.
Sedans (Reduced but Relevant)
- Nissan Sentra – Recently updated and positioned as the primary sedan
- Nissan Altima – Still available, though its long-term future is less certain
As consumer demand shifts toward SUVs, Nissan is scaling back—but not eliminating—its sedan offerings.
Trucks and Performance Models
- Nissan Frontier – A key player in the midsize truck segment
- Nissan Titan – Still present, but facing stiff competition
- Nissan Z – A modern revival of Nissan’s performance heritage
- Nissan GT-R – Nearing the end of its lifecycle, with a successor anticipated
These models help maintain Nissan’s identity beyond everyday transportation.
⚠️ Models Being Phased Out or Reevaluated
Not every vehicle is making the cut.
- The Nissan Versa is being discontinued after 2025
- The Nissan Ariya is seeing strategy adjustments depending on market demand
- Some low-volume global models are being eliminated as part of a broader consolidation effort
This reflects a broader industry shift: automakers are prioritizing efficiency and profitability over sheer volume.
🔍 The Role of the Nissan Kicks
One standout in this transition is the Nissan Kicks, which represents Nissan’s practical, value-driven approach.
Recently redesigned, the Kicks offers:
- Modern infotainment and safety features
- Improved comfort and available all-wheel drive
- Strong fuel efficiency at an affordable price point
While it doesn’t showcase cutting-edge hybrid or EV technology, it plays a crucial role as an entry-level gateway into the Nissan brand.
🧭 Industry Context: Why This Shift Matters
Nissan’s strategy mirrors broader trends shaping the automotive industry:
- EV adoption is growing—but unevenly
- Hybrids are gaining traction as a transitional solution
- SUV demand continues to dominate global markets
- Cost control and profitability are now top priorities
By focusing on fewer, stronger models, Nissan aims to remain competitive in a rapidly evolving landscape.
🧾 Bottom Line
Nissan is not simply cutting models—it’s redefining its identity.
- ✔️ Investing in hybrid technology, AI, and core SUVs
- ✔️ Maintaining key sedans, trucks, and performance vehicles
- ❌ Eliminating underperforming and low-demand models
The result is a lineup that is leaner, more technologically advanced, and better aligned with today’s market demands.
