New prosthetics restore natural movement via nerve connection
In the world of prosthetics, a groundbreaking advancement is changing the game for individuals with lower-limb amputations.
Researchers at MIT, in collaboration with Brigham and Women’s Hospital, have developed a neuroprosthetic system that allows users to control their prosthetic legs using their own nervous systems.
This innovative approach could bring us closer to a future of fully integrated, naturally controlled artificial limbs.

The AMI: A surgical game-changer
At the heart of this breakthrough is a surgical procedure known as the agonist-antagonist myoneural interface, or AMI. Unlike traditional amputation methods, the AMI reconnects muscles in the residual limb, preserving the natural push-pull dynamics of muscle pairs. This seemingly simple change has profound implications for prosthetic control and function.

Dr. Hugh Herr, a professor at MIT and senior author of the study, explained the significance: “This is the first prosthetic study in history that shows a leg prosthesis under full neural modulation, where a biomimetic gait emerges. No one has been able to show this level of brain control that produces a natural gait, where the human’s nervous system is controlling the movement, not a robotic control algorithm.”

The power of proprioception
The key advantage of the AMI system is its ability to provide users with proprioceptive feedback, the sense of where their limb is in space. This sensory information, often taken for granted by those with intact limbs, is crucial for natural movement and control. With the AMI, patients regain a portion of this vital feedback, allowing them to walk more naturally and confidently.
In the study, seven patients with AMI surgery were compared to seven with traditional amputations. The results were striking. AMI patients walked faster, navigated obstacles more easily and climbed stairs with greater agility. They also demonstrated more natural movements, such as pointing their toes upward when stepping over obstacles, a subtle but important aspect of a natural gait.

Adapting to real-world challenges
One of the most impressive aspects of the AMI system is its versatility. Patients were able to adapt their gait to various real-world conditions, including walking on slopes and navigating stairs. This adaptability is crucial for everyday life, where terrain and challenges can change rapidly.
The system’s responsiveness was put to the test in an obstacle-crossing trial. AMI patients were able to modify their gait to clear obstacles more effectively than those with traditional prosthetics. This ability to rapidly adjust to unexpected challenges is a hallmark of natural limb function and represents a significant leap forward in prosthetic technology.

The science of sensory feedback
The success of the AMI system hinges on its ability to augment residual muscle afferents, which are the sensory signals sent from muscles to the nervous system. Remarkably, even a modest increase in these signals allows for significantly improved control and function. This finding highlights the incredible adaptability of the human nervous system and its ability to integrate and utilize even partial sensory information.
Dr. Hyungeun Song, lead author of the study, notes: “One of the main findings here is that a small increase in neural feedback from your amputated limb can restore significant bionic neural controllability, to a point where you allow people to directly neurally control the speed of walking, adapt to different terrain and avoid obstacles.”

Looking to the future
While this research represents a significant step forward, it’s just the beginning. The team at MIT is exploring ways to further enhance sensory feedback and improve the integration between the human nervous system and prosthetic devices. The AMI procedure has already been performed on about 60 patients worldwide, including those with arm amputations, suggesting broad applicability across different types of limb loss.
As this technology continues to evolve, we may see even more natural and intuitive control of artificial limbs. The ultimate goal is to create prosthetics that feel and function like a natural part of the user’s body, blurring the line between human and machine.

Surprise, surprise: Silksong wins Steam’s Game of the Year
Valve has announced the winners of the 2025 Steam Awards and, unsurprisingly, Hollow Knight: Silksong, took home the Game of the Year honors. It was also given the “Best Game You Suck At” award, which, I’m not sure if that’s a good thing or not. Given the relentless fawning over Silksong since its release in September, an event that nearly brought the entire digital video game distribution system to its knees, that it would win Game of the Year felt like something of a forgone conclusion.
The Best Game on Steam Deck was awarded to Hades II (an award we’d already unofficially granted it). The mechanics of Hades lend it to being played in short bursts, and the stylized graphics scale down well. Silent Hill f won the Outstanding Visual Style award and, while there’s no denying it’s a gorgeous title, I can’t help but feel like Dream BBQ, with its uniquely hallucinatory visuals, got robbed. Check out the full list of winners and nominees here at the Steam Awards 2025 landing page.

University of Phoenix data breach hits 3.5M people
NEWYou can now listen to Fox News articles!
The University of Phoenix has confirmed a major data breach affecting nearly 3.5 million people. The incident traces back to August when attackers accessed the university’s network and quietly stole sensitive information.
The school detected the intrusion on Nov. 21. That discovery came after the attackers listed the university on a public leak site. In early December, the university disclosed the incident, and its parent company filed an 8-K with regulators.
The scope is large. Notification letters filed with Maine’s Attorney General show 3,489,274 individuals were affected. Those affected include current and former students, faculty, staff and suppliers.

What happened and how attackers got in
According to the university, hackers exploited a zero-day vulnerability in Oracle E-Business Suite. This application handles financial operations and contains highly sensitive data.
Based on the technical details shared so far, security researchers believe the attack aligns with tactics used by the Clop ransomware gang. Clop has a long track record of stealing data through zero-day flaws rather than encrypting systems.
The vulnerability tied to this campaign is tracked as CVE-2025-61882. Investigators say it has been abused since early August.
What data was exposed
The university says the attackers accessed highly sensitive personal and financial information. That includes:
- Full names
- Contact information
- Dates of birth
- Social security numbers
- Bank account numbers
- Routing numbers
This type of data creates a serious risk. It can fuel identity theft, financial fraud and targeted phishing scams.

Nearly 3.5 million people affected
In letters sent to affected individuals, the university confirmed the breach affects 3,489,274 people. If you are a current or former student or employee, watch your mail closely.
These notifications often arrive by postal mail, not email. The letter explains what data was exposed and includes instructions for protective services.
We reached out to the University of Phoenix for comment, and a rep provided CyberGuy with the following statement:
“We recently experienced a cybersecurity incident involving the Oracle E-Business Suite software platform. Upon detecting the incident on November 21, 2025, we promptly took steps to investigate and respond with the assistance of leading third-party cybersecurity firms. We are reviewing the impacted data and will provide the required notifications to affected individuals and regulatory entities.”
Free identity protection is now available
The University of Phoenix is offering affected individuals free identity protection services. These include:
- 12 months of credit monitoring
- Identity theft recovery assistance
- Dark web monitoring
- A $1 million fraud reimbursement policy
To enroll, you must use the redemption code provided in the notification letter. Without that code, you cannot activate the service.
This attack fits a larger Clop campaign
The University of Phoenix breach is not an isolated case. Clop has used similar tactics in past campaigns involving GoAnywhere MFT, Accellion FTA, MOVEit Transfer, Cleo and Gladinet CentreStack.
Other universities have also reported Oracle EBS-related incidents. These include Harvard University and the University of Pennsylvania.
The U.S. government is taking notice. The U.S. Department of State is now offering a reward of up to $10 million for information linking Clop’s attacks to a foreign government.
Why colleges are prime targets
Universities store massive amounts of personal data. Student records, financial aid files, payroll systems and donor databases all live under one roof.
Like healthcare organizations, colleges present a high-value target. A single breach can expose years of data tied to millions of people.

Steps to stay safe right now
If you believe you may be affected, act quickly. These steps can reduce your risk.
1) Watch for your breach notification letter
Read it carefully. It explains what data was exposed and how to enroll in protection services.
2) Enroll in the free identity protection
First, use the redemption code provided. Because Social Security and banking data are involved, credit monitoring and recovery services matter. Even if you do not qualify for the free service, an identity theft protection service is still a smart move.
In addition, these services actively monitor sensitive details like your Social Security number, phone number and email address. If your information appears on the dark web or if someone tries to open a new account, you receive an alert right away. As a result, many services also help you quickly freeze bank and credit card accounts to limit further fraud.

3) Use a data removal service
Because this breach exposed names, contact details and other identifiers, reducing what is publicly available about you matters. A data removal service can help remove your personal information from data broker sites, which lowers the risk of targeted phishing or fraud tied to the stolen University of Phoenix records.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

4) Monitor financial accounts daily
Check bank statements and credit card activity for unfamiliar charges. Report anything suspicious immediately.
5) Consider freezing your credit
A credit freeze can stop criminals from opening new accounts in your name. It is free and reversible. To learn more about how to do this, go to Cyberguy.com and search “How to freeze your credit.”
6) Be alert for phishing attempts and use strong antivirus software
Expect more scam emails and phone calls. Criminals may reference the breach to sound legitimate.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.
Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com
7) Secure your devices
Keep your operating systems and apps up to date, as attackers often exploit outdated software to gain access. In addition, enable automatic updates and review app permissions to prevent stolen personal data from being combined with device-level access and causing further harm.
Kurt’s key takeaways
The University of Phoenix data breach highlights a growing problem in higher education. When attackers exploit trusted enterprise software, the fallout spreads fast and wide. While free identity protection helps, long-term vigilance matters most. Staying alert can limit damage long after the headlines fade.
If universities cannot protect this level of sensitive data, should students demand stronger cybersecurity standards before enrolling? Let us know by writing to us at Cyberguy.com

LG announces new UltraGear evo gaming monitors with AI upscaling
LG unveiled a whole new line of gaming monitors ahead of CES on Friday. The UltraGear evo line are all high-end monitors covering a range of technologies, but united by 5K resolution and AI upscaling.
The three flagships under the new branding are the 39GX950B, the 27GM950B, and the 52G930B. The first number in the model name indicates the size. The rest of the letters and numbers, well, I’m sure they mean something to someone.
The 39-inch GX9 is an ultrawide 21:9 5K2K dual-mode OLED screen. It can run at its full resolution at 165Hz, or jump to 330Hz for fast-twitch games at WFHD. The 27-inch GM9 uses “New” MiniLEDs, which promise to deliver brighter images compared to OLED, without the blooming often associated with MiniLEDs. Lastly, the 52-inch G9 is an absolutely massive curved display that delivers a 12:9 panoramic view at 240Hz in its native 5K2K resolution.
The GM9 model is particularly interesting since LG makes the panels for Apple’s Pro Display XDR, and word is that the monitor is finally getting a long-overdue update in the near future.
All three monitors will be on display at CES next month, but there’s no word on pricing or availability just yet.
