Alexa becomes your personal home monitor

Turn your assistant into a digital guardian with this hidden feature that keeps an eye on your home when you're away.

Your sarcastic new digital bodyguard

It seems that Alexa has finally decided to earn those pennies that Amazon invested in her, leaving behind her fascinating career as a bad joke teller and reminder programmer to become your personal watchdog. What a relief to know that while you are enjoying a vacation, this talking cylinder transforms into a digital bodyguard that, although it has no eyes (i.e. camera), can at least feel vibrations like a teenager on his first date.

The brilliant mind behind this device has discovered that it can use ultrasound sensors to detect movement, because clearly listening to our private conversations wasn’t enough fun anymore. Now you also need to know if we are moving too much. Do you want to transform your Echo into a security alert? Get ready for a digital bureaucratic adventure that would make any government bureaucrat cry.

The configuration ritual: more complicated than programming the microwave

According to the geniuses at Amazon, these devices only emit ultrasound after you activate a function that requires motion detection. How thoughtful they don’t want to bombard us with unnecessary sound waves while we watch Netflix. The alert signals come through the app, because obviously we need another notification that gets lost among the memes and work emails.

The first step on this exciting journey towards controlled paranoia is to activate motion detection. Open the Alexa app (the one you never use), go to “Devices” (where you probably have three versions of the same device without knowing which one is which), select the device you want to configure (good luck guessing), go to “Device Settings” (the place where all your hopes are going to die), and finally activate the ultrasonic motion detection box. Simple, right? Almost as intuitive as programming your grandparents to use TikTok.

But wait, there’s more! Now you need to establish a routine for the presence of people. Because Alexa isn’t satisfied with just knowing that you move – she needs to create habits around your movement patterns. According to Amazon’s official portal, these routines work “when an Echo device detects that someone is nearby.” What a profound revelation – almost like saying that water is wet.

When your home becomes smarter than you

Thanks to this technological marvel, Alexa can detect when people are nearby using various methods such as ultrasound, computer vision, or probably by guessing with a digital crystal ball. Imagine the scene: an intruder sneaks into your room and, instead of calling the police, Alexa automatically activates the news summary, plays music by Enya and turns on the lights in your Smart Home. Because nothing deters a thief like ambient lighting and financial news.

To create this masterpiece of home automation, you need to follow these steps that will make assembling IKEA furniture seem like child’s play: Open the Alexa app (again), go to “More” (the digital catchall), select “Routines” (because your life needs more structure), press “More” (there is never enough “more”), select “When” and then “Smart Home” (because your house is now smarter than you).

Then choose the device, activate the corresponding boxes for when people are detected or not (because loneliness also deserves automation), add actions and finally save. Just eight steps to achieve what a guard dog does instinctively.

Of course, not all Echo devices are modern enough for this ultrasound monitoring function. Only the most recent models have this privilege, because in the world of technology, planned obsolescence is the name of the game. Echo Shows with cameras can use computer vision, meaning they not only hear and sense your movement, but they can also see you at your best (or worst).

Satellite Internet, the bet to close the digital divide in Mexico

Mexican geography limits fiber deployment, but low orbit satellites are emerging as an alternative.

Satellite internet as a solution to the digital divide in Mexico

Mountains, jungles and deserts make Mexico one of the countries with the most complex orography in Latin America. Bringing fiber optics to isolated communities implies an investment that is difficult to recover with few users. As a result, one in five households still lack internet access or receive poor service.

Faced with this scenario, low orbit (LEO) satellite internet is emerging as a strategic alternative. “Deploying physical infrastructure in Mexico is expensive due to geography. In many cases, satellite internet represents the most viable option to connect areas where fiber will not reach in the short term,” explains Ernesto Piedras, director of The CIU. Companies like Starlink, with more than 10,300 active satellites, already operate in the country. Since May 2021, it obtained a concession and closed 2024 with 160,631 subscriptions, making Mexico its second Latin American market, only behind Brazil. Starlink has signed contracts with CFE Telecomunicaciones for up to 1,556 million pesos to connect remote communities.

However, cost remains a barrier. While a fiber optic plan costs an average of 544 pesos per month, satellite internet starts at 899 pesos, plus equipment and installation. “Commercially it is still not as viable because it is still more expensive and requires purchasing an antenna whose price remains high,” says Fernando Esquivel, from The CIU. The service makes economic sense when it is shared between communities or companies, and with the support of public policies.

Experts agree that this technology will not replace fiber optics, but will complement it. “Terrestrial services are faster and have lower latency. Satellite communication reaches areas that fixed internet would not reach,” says Hugo Simg, from MediaTek. Deployment also requires regulation and coordination between governments and companies. The race to connect Mexico is no longer only being fought underground, but from space, where a new generation of satellites promises to reduce the digital divide that keeps millions out of the digital world.

Banks prepare for biometric facial controls in October

Banks claim to be ready for facial biometrics in branches since October.

The main banking institutions in the country claim to be prepared for the new regulations on facial biometric controls when opening accounts, which will come into force next October.

What did the banks declare?

Marcos Ramírez, general director of Grupo Financiero Banorte, pointed out that the institution has made progress to reinforce the identification and security of its users. “We are in time and form with everything established by law and a little ahead, with the prudential limits of the law,” he indicated.

These measures will strengthen control over customer identification. Since 2018, by regulation, fingerprint biometrics are already required to open accounts.

Implementation details

On July 1, the National Banking and Securities Commission (CNBV) incorporated facial biometrics into the regulation for multiple banking in customer identification and authentication. Institutions that opt ​​for this mechanism must comply with technical, operational and security requirements.

AI detects breast cancer with 90% accuracy

An autonomous model analyzes thermographs and classifies tissues without human intervention.

An artificial intelligence model developed by Raúl Castro Ortega, a researcher at the Polytechnic University of Tulancingo, manages to identify breast cancer with an accuracy of 90%. The results were presented during the SPIE Photonics Europe 2026 International Congress, in Strasbourg, France.

How the system works

The system uses convolutional neural networks with attention mechanisms to analyze breast thermographs. Unlike traditional methods, the model autonomously learns the patterns of healthy and diseased tissue, without a specialist previously defining the characteristics of the images. This reduces processing time and improves consistency of results.

The study, titled “Breast thermography analysis using convolutional neural networks with attention mechanisms,” uses an algorithm based on the heat diffusion equation. This approach focuses analysis on thermogram regions of interest and classifies tissues with high levels of sensitivity and specificity.

Impact on early detection

The accuracy achieved represents a significant advance for the early detection of breast cancer, which can improve survival rates and facilitate timely treatment. The researcher highlighted that the system does not replace the specialist, but rather works as a support tool for faster and more consistent diagnoses.
