Nexus supercomputer delivers AI speed and power

This system is fast. We’re talking really fast. Nexus will hit over 400 petaflops of performance, meaning it can run 400 quadrillion operations every second. To put that in perspective, it’s like giving every person on Earth the ability to solve 50 million math problems at the same time. But speed isn’t the only headline here. The designers built Nexus specifically for AI workloads and research that needs serious compute muscle. With this much speed behind them, scientists can tackle complex problems in health, energy, robotics, climate and more, faster than ever.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

AI architecture drives Nexus from the ground up

Nexus isn’t just another general-purpose machine with a layer of AI added later. Georgia Tech built it from the ground up with artificial intelligence, machine learning and large-scale data science in mind, right alongside traditional high-performance computing needs.

The system will feature 330 terabytes of memory and 10 petabytes of flash storage, about the digital equivalent of 10 billion reams of paper. That level of infrastructure is essential for training large AI models, running complex simulations and managing massive datasets that don’t fit on standard systems.

Speed is a priority throughout. The data infrastructure is fully optimized to move information between components seamlessly, without bottlenecks. That means researchers can push the limits of their workflows without delays and slow file transfers or memory shortfalls holding them back.

What this means for you

If you’re outside the research world, Nexus still affects you. This system supports work that touches real lives. From drug discovery and vaccine development to building smarter energy systems and improving weather predictions, the breakthroughs powered by Nexus could make it into your home, your hospital, your car or your city.

If you’re a researcher, developer or engineer, Nexus changes the game. You no longer need to be inside a massive Silicon Valley lab to access top-tier AI infrastructure. Whether you’re modeling protein folding, training a new algorithm or simulating complex weather systems, this machine will give you the tools to do it faster and better.

This isn’t just about one machine. It’s about opening up access to innovation. More researchers will get to run more experiments, ask bigger questions and share ideas across disciplines without being limited by infrastructure. That’s a win for all of us.

Kicking a ball or climbing stairs with ease after a leg amputation above the knee is now within reach. Researchers at MIT have developed a bionic knee that redefines mobility for above-the-knee amputees. Unlike traditional socket-based prosthetics, this system anchors directly to the bone and integrates with the surrounding muscle tissue. The result is faster, smoother, and more natural movement.

Led by Professor Hugh Herr, the MIT team created a solution that doesn’t just mimic motion, it responds to intent. This level of control allows the prosthesis to move in sync with the body, delivering a seamless experience that challenges the very definition of artificial limbs.

How the e-OPRA bionic knee for amputees works

The tech is called e-OPRA (Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees). It involves surgically implanting a titanium rod into the femur, which connects directly to a robotic prosthetic limb. This rod becomes the foundation of a new kind of interface between the body and machine. But it doesn’t stop there.

Using a specialized surgical technique known as Agonist-Antagonist Myoneural Interface (AMI), muscles are reconnected in functional pairs. These muscles “talk” to each other, sending signals to the robotic controller, which calculates exactly how the knee should move, mirroring how a real leg works. 

Natural movement restored with the bionic knee for amputees

In trials, two patients with this integrated system not only performed better, but they also felt better. They moved faster, climbed stairs with more ease, and avoided obstacles with greater confidence. Most importantly, they felt like the prosthetic was part of their body.

One participant with only a few inches of thigh remaining could walk, pivot, and even kick a ball smoothly. This kind of intuitive, natural movement is a game-changer for above-the-knee amputees.

Why the bionic knee for amputees is a major breakthrough

Traditional socket-based prosthetics can be uncomfortable, unstable, and prone to infections. They often feel foreign, like a tool strapped to the body rather than a part of it. The bionic knee bypasses the socket altogether. By connecting directly to bone and muscle, it improves load-bearing, reduces skin problems, and most importantly, restores a sense of control. And control isn’t just physical, it’s emotional and psychological. Patients using the e-OPRA system reported a greater sense of agency and body ownership than those with traditional or partially-integrated prosthetics.

MIT’s bionic knee for amputees driven by lived experience

Professor Hugh Herr isn’t just leading the research; he’s living it. After losing both legs below the knee to frostbite in his teens, he returned to mountain climbing and dedicated his career to advancing prosthetic technology. His personal journey powers a lab at MIT that continues to push the boundaries of biomechatronics. And now, that journey may change the lives of above-the-knee amputees worldwide.

When the bionic knee for amputees will be available

While the results are groundbreaking, the e-OPRA system isn’t on the market yet. Larger clinical trials and FDA approval are still ahead. Herr estimates that within five years, this technology could become more accessible to patients. 

Kurt’s key takeaways

We’re witnessing the future of prosthetics unfold. The bionic knee developed by MIT doesn’t just restore function, it redefines it. By merging advanced robotics with the human nervous system, it offers amputees something priceless: the feeling that their body is whole again.

Border Patrol is about to get a powerful new ally, and it doesn’t bark. A microwave-sized device called VaporID could soon replace drug-sniffing dogs at U.S. border crossings. Built to detect fentanyl, cocaine, methamphetamine, MDMA, ketamine, and even explosives, the tech is showing accuracy and speed that trained dogs simply can’t match.

How VaporID detects drugs faster than swab tests

This portable air scanner, created at the Department of Energy’s Pacific Northwest National Laboratory (PNNL), is being brought to market by California-based instrument maker BaySpec. The device works by pulling in air and identifying molecules in real time using a miniature mass spectrometer.

Unlike traditional swab tests that take five to thirty minutes, VaporID detects fentanyl in seconds, even at levels as low as six parts per trillion. That’s like spotting a single pine needle in an entire forest.

Why drug dogs may soon be outmatched by VaporID

For decades, trained canines have been the gold standard at ports of entry. But dogs have limits; they tire, need handlers, and can’t be reprogrammed with software updates. VaporID, on the other hand, never needs a nap. It can detect not only known drugs but also fentanyl analogs, lab-made variants designed to skirt detection.

The system’s cutting-edge design includes an atmospheric flow tube that allows tiny drug molecules more time to interact with charged ions. That chemical dance dramatically boosts sensitivity, making it possible to detect even the most elusive threats.

During a real-world field trial at the Nogales, Arizona border crossing, the device detected trace amounts of several drugs, including fentanyl and cocaine, within seconds inside a Customs and Border Protection lab.

How VaporID works: Air, ions, and instant answers

VaporID weighs about 40 pounds and draws in ambient air like a miniature vacuum. Suspicious molecules are filtered, tagged with electrically charged ions, and passed into a tiny mass spectrometer. Only the relevant particles make it through. This process filters out background interfering vapors from things like perfumes or cleaning agents, giving border agents a clear, accurate, and immediate read on potentially dangerous substances.

What VaporID means for border security

If deployed widely, VaporID could revolutionize how U.S. Customs and Border Protection detects narcotics and explosives. Its fast, hands-free scanning would help agents screen vehicles, cargo, luggage, and even people, without relying solely on canine units or invasive sampling.

The device’s sensitivity also opens doors for use beyond borders. The Department of Homeland Security is already working with PNNL and BaySpec to adapt the technology for mail screening, airport baggage checks, and large-scale cargo inspections.

For materials like TNT (trinitrotoluene) and PETN (pentaerythritol tetranitrate), both powerful explosives that release very few molecules into the air, VaporID’s ultra-sensitive detection provides a level of protection that’s long been out of reach with current methods.

VaporID’s role in combating drug and explosive smuggling

The U.S. is facing a deadly influx of synthetic opioids. According to the CDC, over 80,000 Americans died from drug overdoses in 2024, including approximately 48,400 deaths linked to fentanyl and other synthetic opioids. Fast, contactless detection at ports of entry could help choke off the supply chain before these deadly substances ever hit the streets. And in an era of rising geopolitical tensions, having a portable scanner that can also detect explosives could be a critical layer in national defense.

Kurt’s key takeaways

Technology doesn’t just assist border agents anymore; it’s starting to outperform their most trusted tools. VaporID brings speed, precision, and reliability to a job where seconds count. While drug-sniffing dogs have served well, this portable air scanner may soon lead the front line in detecting threats. As agencies prepare to roll out the system, one thing is clear. The future of border security doesn’t bark. It beeps.

When I think about my golden years, I picture myself enjoying new hobbies and spending more time with loved ones. Yet, some of the very things that mark a well-lived life, like a fixed address, a long-time phone number, and a healthy savings account, also put you at risk of scams.

That’s why you must protect your personal information. Today, it stands as the number one target for fraud. According to recent studies, 72% of elder fraud cases involve exposed personal data.

Managing data privacy for older adults has become increasingly difficult. Threats evolve constantly, security settings change frequently, and scammers get smarter. Fortunately, you don’t have to handle this alone.

How a trusted loved one can help protect data privacy for older adults

One of the best ways to protect your data is by bringing a trusted loved one into the loop. This person can serve as your privacy partner, helping you stay safe while respecting your independence.

• Spot phishing scams and fake messages.
• Set up call blockers and scam filters, and adjust security settings.
• Remove your personal information from the web.
• Keep an eye on suspicious activity without taking over control.

Choosing the right person to help with data privacy for older adults

That person could be a grown child, a niece or nephew, a sibling, or even a longtime friend. The key is finding someone tech-comfortable and dependable, someone who respects your boundaries.

Keep in mind, almost 58% of financial exploitation of older adults is perpetrated by family members, so being related doesn’t automatically make someone trustworthy. Before giving anyone access to your accounts or personal information, ask yourself:

• Have they ever pressured me about money?
• Do they respect my decisions and boundaries?
• Would I trust them with my house keys or bank card?

Privacy checklist for older adults: What to protect

Think of this like walking through your house and checking which doors need locks. Your digital life needs the same attention, and it helps to know where you might want backup. Here’s a quick rundown of what to look at, why it matters, and when help is appropriate:

Phone number

Your cell phone number is often tied to two-factor authentication (2FA), account recovery, and scams like SIM swapping. It’s smart to set up call blockers and lock your SIM. This is something someone tech-savvy can help you with.

Home address

Your address can be used in phishing attacks or even in-person scams. If it’s listed on people-search sites, someone can help you remove it.

Email account

This is the gateway to most of your online life. Setting up strong two-factor authentication and email filters is a good idea. You might want help, but only if you trust the person completely.

Bank accounts

These are high-value targets. No one should have your passwords, but you can accept help setting up fraud alerts or reviewing account settings together.

Medical portals

They hold sensitive health and billing info. You might want help making sure your logins are secure, but no one else needs access.

Social media accounts

These can be used to impersonate you or collect information. It’s okay to get help locking down your privacy settings.

Shopping accounts

Many store your address and credit card info. A trusted helper can assist you with clearing out old or unused accounts.

Pro tip: Jot this list down or print it out. Check off the areas where you’d like help, and mark the ones you’ll handle solo. This makes conversations with family, caregivers, or tech support much easier and sets clear boundaries. And remember: you don’t need to give full access to anyone. A little help is fine, but your privacy is yours to control.

Essential privacy protections older adults should set up with a trusted partner

Once you’ve got your privacy partner and checklist in place, it’s time to start locking things down. These basic protections stop most scams before they start, and you don’t need to be a tech expert to get them working.

1) Phone & device security

• Add a SIM PIN so no one can steal your number.
• Install a spam call blocker.
• Set a strong screen lock (PIN, fingerprint, or face ID).
• Turn on automatic updates so your software stays secure.
• Use a password manager to keep logins safe and organized.

Get more details about my best expert-reviewed Password Managers of 2025 at Cyberguy.com/Passwords.

2) Scam & spam filtering

• Turn on spam filters in your email.
• Don’t respond to strange texts or emails, even if they sound urgent.
• Mark anything suspicious as spam (don’t click or reply).

3) Financial safeguards

• Set up bank alerts for large or strange transactions.
• Add a trusted contact to your bank profile (not full access, just someone to notify).
• If needed, give read-only access to someone you trust to monitor, not manage your accounts.
• Ask your bank about fraud protection options for older adults.
• Talk to a lawyer if you want to set up a Power of Attorney for emergencies.

4) Data removal

• Remove personal information from social media and set profiles to private.
• Remove personal information from people search sites and data brokers.
• Let your privacy partner help monitor opt-out progress, but stay in the loop yourself.
• Consider using a data removal service to keep your personal information offline.
