Noninvasive brain tech and AI moves robotic hand with thought

Noninvasive brain tech is transforming how people interact with robotic devices. Instead of relying on muscle movement, this technology allows a person to control a robotic hand by simply thinking about moving his fingers.

No surgery is required.

Instead, a set of sensors is placed on the scalp to detect brain signals. These signals are then sent to a computer. As a result, this approach is safe and accessible. It opens new possibilities for people with motor impairments or those recovering from injuries.

PARALYZED MAN SPEAKS AND SINGS WITH AI BRAIN-COMPUTER INTERFACE

Researchers at Carnegie Mellon University have made significant progress with noninvasive brain technology. They use electroencephalography (EEG) to detect the brain's electrical activity when someone thinks about moving a finger. Artificial intelligence, specifically deep learning algorithms, then decodes these signals and translates them into commands for a robotic hand. In their study, participants managed to move two or even three robotic fingers at once, just by imagining the motion. The system achieved over 80% accuracy for two-finger tasks. For three-finger tasks, accuracy was over 60%. All of this happened in real time.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Achieving separate movement for each robotic finger is a real challenge. The brain areas responsible for finger movement are small. Their signals often overlap, which makes it hard to distinguish between them. However, advances in noninvasive brain technology and deep learning have made it possible to pick up on these subtle differences.

The research team used a neural network called EEGNet. They fine-tuned it for each participant. Because of this, the system allowed for smooth, natural control of the robotic fingers. The movements closely matched how a real hand works.

For people with limited hand function, even small improvements can make a huge difference. Noninvasive brain technology eliminates the need for surgery because the system is external and easy to use. In addition, this technology provides natural and intuitive control. It enables a person to move a robotic hand by simply thinking about the corresponding finger movements.

The accessibility of noninvasive brain technology means it can be used in clinics and homes and by a wide range of people. For example, it enables participation in everyday tasks, such as typing or picking up small objects that might otherwise be difficult or impossible to perform. This approach can benefit stroke survivors and people with spinal cord injuries. It can also help anyone interested in enhancing their abilities.

While the progress is exciting, there are still challenges ahead. Noninvasive brain technology needs to improve even further at filtering out noise and adapting to individual differences. However, with ongoing advances in deep learning and sensor technology, these systems are becoming more reliable and easier to use. Researchers are already working to expand the technology for more complex tasks.

As a result, assistive robotics could soon become a part of more homes and workplaces.

Noninvasive brain technology is opening up possibilities that once seemed out of reach. The idea of moving a robotic hand just by thinking about it could make daily life easier and more independent for many people. As researchers continue to improve these systems, it will be interesting to see how this technology shapes the way we interact with the world around us.

Top multi-factor authentication apps to protect your accounts

Hackers often exploit reused passwords, gaining access to multiple accounts if just one is compromised. To stay safe, use strong, unique passwords for every account and change them regularly. However, passwords alone aren't enough. That's where multi-factor authentication apps come in.

Multi-factor authentication (MFA) adds an extra layer of protection to your accounts. Instead of relying only on a password, MFA requires you to verify your identity using two or more methods. These can include SMS codes, authenticator apps, or physical security keys.

Two-factor authentication (2FA) is a type of MFA that uses exactly two verification methods. MFA, on the other hand, can involve two or more factors. For example, logging into your bank might require a password and a code from an app-this is MFA in action.

Not all websites and apps support every type of MFA, so your choice may depend on what's available. Here's how the main options compare:

Many banks use SMS for two-factor authentication because it's easy to set up and works on any phone. However, SMS is not the most secure method. Authenticator apps and physical security keys offer better protection against modern threats.

Unfortunately, there's no universal MFA solution for every account. The best approach is to use the strongest MFA method each service supports. Whenever possible, choose an authenticator app or a physical security key over SMS.

Using a multi-factor authentication app is one of the best ways to protect your online identity. Here are some of the top-rated options available for iPhone and Android:

The Microsoft Authenticator app gives you an easy, secure sign-in experience for all your accounts and gives you additional account management options for your Microsoft personal, work, and school accounts. It can use multi-factor authentication with a one-time passcode, can go password-less by using your phone instead of a password to log in, or can use autofill passwords for you. It's easy to use and can keep multiple accounts safe and secure for you.

Twilio Authy is another great app that you can use for all your accounts, including Facebook, Dropbox, Amazon, Gmail, and thousands more. It provides secure cloud-encrypted backups so that you will never lose access to your accounts, even if you lose your device. The app uses the same algorithms as many banks and the NSA use to protect their information, so you can pretty much guarantee that you'll be safe. Plus, you can even use it if you're offline or in airplane mode.

The Google Authenticator app will give you an extra layer of security for your online apps. You can sync your authenticator codes to your Google Account and across your devices. It offers support for multiple accounts, and you can transfer accounts between devices by using a QR code. Plus, you can choose the type of code generation used that best suits your needs, and it works without a network or cellular connection.

The Aegis Authenticator app is a free option for Android users. It is a great app to protect your online accounts from hackers and phishing. It adds an extra layer of security by generating one-time codes that you need to enter alone with your password. This way, even if a hacker steals your password, they won’t be able to access your account with your phone. The Aegis Authenticator app also lets you customize and organize your accounts, backup and restore your data, and use it offline.

While multi-factor authentication adds critical protection, it works best when combined with strong, unique passwords for every account. That’s where a password manager comes in. Instead of trying to memorize dozens of complex passwords, a password manager securely stores them for you and automatically fills them in when needed. It can generate strong, random passwords, store them in an encrypted vault, and sync across your devices so you always have access. Using NordPass along with multi-factor authentication is one of the best strategies to keep your accounts and personal data safe from hackers.

Keeping your accounts safe doesn't have to be complicated. By using multi-factor authentication apps, you're adding a strong layer of protection that goes beyond just passwords. These apps make it much harder for hackers to get in, even if they somehow learn your password. Ready to take your security up a notch?

AI brain scan tool predicts how fast you are aging

Our bodies change as we get older, and one undesirable result is that we become more vulnerable to age-related issues. Particularly, old age is characterized by a significant physical and mental decline. But why is it that some people thrive in their later years, while others face several health challenges prematurely? It's as if some people age faster than others.

To get to the bottom of this, scientists from Duke, Harvard, and the University of Otago have unveiled a game-changing tool called DunedinPACNI. It uses a single AI brain scan to reveal how fast a person is biologically aging. It's changing the way we track aging and the long-term health risks associated with it.

The DunedinPACNI was named after the Dunedin Study, which followed over 1,000 people since their birth in the 1970s. Researchers analyzed decades of data, looking at factors like blood pressure, BMI, cholesterol, glucose, kidney function, and even dental health, to come up with a unique "aging score" for each participant. The new MRI-based AI brain scan can predict this score with surprising accuracy from a scan taken at age 45.

Participants whose aging scores were faster showed early signs of memory-related brain changes, such as shrinkage of the hippocampus. Follow-up studies of people aged between 52 and 89 showed that those aging rapidly were 60% more likely to develop dementia, 18% more likely to be diagnosed with chronic illnesses, and 40% more likely to die within the same period compared to those who were aging at a slower pace. This data shows that brain aging and overall physical decline are closely linked.

The team believes DunedinPACNI could change the landscape of preventive medicine. If it were possible to spot health risks early through an AI brain scan, at-risk individuals might be motivated to make healthier lifestyle changes (e.g., diet, exercise, and stress management). It could also help healthcare providers evaluate the effectiveness of treatment and slow the progression of age-related diseases.

The DunedinPACNI is a great tool that offers a non-invasive and powerful window into biological aging that traditional blood tests never could. A single AI brain scan provides a lifetime of health insights. It comes at a much-needed time as chronic diseases are on the rise. It may just be one of the key ingredients in predicting health outcomes and coming up with personalized wellness strategies.

Fake agent phone scams are spreading fast across the US

A disturbing wave of fake agent phone scams is sweeping across the United States, catching people off guard and draining their savings. These criminals do not just pretend to be someone you trust; they impersonate federal agents, threaten arrest, and demand payment on the spot. As the schemes become more sophisticated, the FBI and other law enforcement agencies are issuing urgent warnings. Moreover, the scams are spreading rapidly and becoming increasingly difficult to spot.

Often, it begins with a phone call that appears legitimate. The number might display familiar initials, such as "FBI," "US Marshals," or even your local police department. Scammers use spoofing technology to fake caller IDs, making the call look official. During the call, the scammer creates panic with claims like:

To avoid immediate legal trouble, victims are often instructed to pay immediately, usually through prepaid gift cards, cryptocurrency ATMs, or wire transfers. These demands are designed to be untraceable and irreversible. Importantly, the US Marshals will NEVER call you to collect money, the agency emphasized in a public warning.

Reports of these calls have come in from New York, Illinois, Virginia, and nearly every other state. Some victims have lost thousands of dollars. In Michigan, scammers increased their credibility by using the real names and ranks of local officers. Meanwhile, in Maryland, suspects posing as FTC agents even showed up in person twice to collect cash. This scam is not limited to phone calls. Text messages, known as "smishing" attacks, are also on the rise. One version targeted iPhone users with fake DMV payment demands. According to cybersecurity firm Guardio, smishing surged 773% in just one month.

Why fake agent phone scams succeed and how they manipulate trust

Fraudsters know how to exploit fear effectively. They count on the fact that most people will do almost anything to avoid arrest or protect a family member. By spoofing official numbers, they undermine our first line of defense: trust. However, it is not just about technology. Experts also warn of an emotional manipulation crisis. These scammers don't just steal your money, they steal your identity too. As a result, victims feel violated, scared, and uncertain about whom to trust.

Concerns are growing about how far these scams could go. Law enforcement and cybersecurity experts warn that scammers may soon use:

While there's no direct evidence of those advanced tactics yet, experts agree they're coming, and fast.

These scams are designed to trigger panic and override your judgment. But a few simple actions can protect you and your loved ones from falling victim. Stay sharp, stay skeptical, and follow these smart steps:

If someone calls claiming to be from a government agency and demands money, don't explain or ask questions; just hang up. Real law enforcement will never ask for payment over the phone, and they won't threaten you into silence.

No legitimate government agency will ever ask you to settle a legal issue with a prepaid gift card or a trip to a Bitcoin ATM. These are hallmark signs of a scam, designed to move your money fast and leave no trace.

The number on your screen might look official, but spoofing technology can fake any number, even 911 or the FBI. If the caller creates pressure or fear, hang up and verify using an official number from the agency's website.

Even if you don't fall for the scam, reporting it can help authorities track these operations. Contact your local FBI field office, your state's Attorney General, or file a report at reportfraud.ftc.gov. Every report helps build a stronger case.

Scammers often target people who are more likely to believe a false threat, especially seniors or non-native English speakers. Have a conversation with family and friends so they know what to look out for and what to do if they receive a suspicious call or message.

Many scammers do their homework before making contact. They might already know your name, address, or even a relative's name to sound more convincing. Using a reputable personal data removal service can reduce the chances of your private information being misused. The less data available online, the fewer hooks criminals have to grab onto.

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.

Some scams are shifting from voice calls to text messages. If you receive a message claiming to be from the DMV, IRS, or law enforcement, don't click any links. These texts (known as "smishing" attacks) can trick you into entering personal info or downloading malware.

The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have 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.

These criminals are getting smarter, but so can we. Staying informed and understanding what real law enforcement will never do is key to protecting yourself and your family. Authorities will not threaten you over the phone, demand gift cards or cryptocurrency, or ask you to prove your innocence with money. If something feels off, trust your gut. Also, spread the word, because the more people who know, the harder it is for these criminals to succeed.
