Engineers at the University of California San Diego have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.

The findings are detailed in a paper published on June 12 in Science Advances.The microrobots are an ingenious combination of biology and nanotechnology. They are a joint effort between the labs of Joseph Wang and Liangfang Zhang, both professors in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at the UC San Diego Jacobs School of Engineering.

To create the microrobots, researchers chemically attached drug-filled nanoparticles to the surface of green algae cells. The algae, which provide the microrobots with their movement, enable the nanoparticles to efficiently swim around in the lungs and deliver their therapeutic payload to tumors.

he U.S. Department of Justice (DOJ) today said they arrested the alleged operator of 911 S5, a ten-year-old online anonymity service that was powered by what the director of the FBI called “likely the world’s largest botnet ever.” The arrest coincided with the seizure of the 911 S5 website and supporting infrastructure, which the government says turned computers running various “free VPN” products into Internet traffic relays that facilitated billions of dollars in online fraud and cybercrime.

On May 24, authorities in Singapore arrested the alleged creator and operator of 911 S5, a 35-year-old Chinese national named YunHe Wang. In a statement on his arrest today, the DOJ said 911 S5 enabled cybercriminals to bypass financial fraud detection systems and steal billions of dollars from financial institutions, credit card issuers, and federal lending programs.

Updated Saturday, June 1: This article has been updated to include clarifcation around the safety of using public Wi-Fi networks and additional advice from the NCSC and FCC.

Although some people might worry about the National Security Agency itself spying on their phones, the NSA has some sage advice for iPhone and android users concerned about zero-click exploits and the like: turn it off and on again once per week.

How often do you turn off your iPhone or android device? Completely turn it off and then reboot it, rather than just going into standby mode, that is. I suspect that the answer for many people is only when a security or operating system update requires it. That, according to the NSA, could be a big mistake.

Users can mitigate the threat of spear-phishing, which can lead to the installation of yet more malware and spyware, by the same simple action. However, the NSA document does warn that the turn it off and on again advice will only sometimes prevent these attacks from being successful.

AI tools are getting better at cloning people’s voices, and scammers are using these new capabilities to commit fraud. Avoid getting swindled by following these expert tips.

YOU ANSWER A random call from a family member, and they breathlessly explain how there’s been a horrible car accident. They need you to send money right now, or they’ll go to jail. You can hear the desperation in their voice as they plead for an immediate cash transfer. While it sure sounds like them, and the call came from their number, you feel like something’s off. So, you decide to hang up and call them right back. When your family member picks up your call, they say there hasn’t been a car crash, and that they have no idea what you’re talking about.

Congratulations, you just successfully avoided an artificial intelligence scam call. Continue reading “How to Protect Yourself (and Your Loved Ones) From AI Scam Calls” →

Majority of Consumers Feel Safe With DIY Home Security: Parks Study

Majority of Consumers Feel Safe With DIY Home Security: Parks Study

Some 60% of consumers believe their self-monitoring home security systems keep them just as safe as monitoring provided by security pros, according to research released by Parks Associates.

“Consumers view self-monitoring as a way to be notified of what’s going on in their homes. For many of them, that can provide the peace-of-mind that’s safe enough for certain households,” Parks President and CEO Elizabeth Parks told TechNewsWorld.

Based on a survey of 8,000 U.S. internet households, the research also found that the major reason for canceling professional monitoring systems was cost, with 25% of consumers citing “fees too high” as their reason for terminating their monitoring services.

Also mentioned as reasons for cutting professional monitoring were an increased sense of neighborhood safety and a realization that the household doesn’t use its system enough.

While many consumers feel their self-monitoring systems keep them safe, professional monitoring services remain popular.

A Titanic Geopolitical Struggle Is Underway

 A Titanic Geopolitical Struggle Is Underway

There are many ways to explain the two biggest conflicts in the world today, but my own shorthand has been that Ukraine wants to join the West and Israel wants to join the Arab East — and Russia, with Iran’s help, is trying to stop the first, and Iran and Hamas are trying to stop the second.

While the two battlefronts may look very different, they actually have a lot in common. They reflect a titanic geopolitical struggle between two opposing networks of nations and nonstate actors over whose values and interests will dominate our post-post-Cold War world — following the relatively stable Pax Americana/globalization era that was ushered in by the fall of the Berlin Wall in 1989 and the collapse of the Soviet bloc, America’s chief Cold War rival.

Yes, this is no ordinary geopolitical moment.

Media disinformation operation with Wagner Group link takes aim at American influence on continent

Russian intelligence agencies are trying to undermine U.S. influence in Africa by spreading disinformation that Africans have been the unwitting test subjects in Pentagon biological research programs and casting aspersions on Western public-health programs, U.S. officials said. 

The effort is part of a Russian campaign to counter the U.S. in Africa and Latin America as Washington and Moscow battle for public opinion around the world. 

At the heart of the Russian campaign is “African Initiative,” an online news service set up late last year that has used social media to promote criticism of Western public-health efforts in Africa and convened a conference in which participants disparaged Western pharmaceutical companies.

In 2024, Biosensors Are Becoming More Accessible: What It Means for You

In 2024, Biosensors Are Becoming More Accessible: What It Means for You

New biowearables are giving people with Type 2 diabetes more options. Those without diabetes can get even more insight into their health.

Deep in your body, under your skin, are measurable elements of your health that affect your risk of developing some of the most common diseases worldwide. Some of these things, like blood oxygen and sleep quality, can be detected through a traditional wearable or smartwatch. But some of the other useful data people can actually act on to become more healthy has either been restricted to prescription devices or simply hasn’t been available in the US. Think your blood sugar levels.

Improvements in biosensing technology are inching closer to changing the wearable status quo. At CES this year, companies came forward with the latest developments in biosensors, which have been in the works for years but only recently started to shape into something the “average” consumer could benefit from. This includes the one in three US adults in “prediabetes” territory, where blood sugar levels are high but not yet high enough to constitute a Type 2 diabetes diagnosis. 

Could biosensors, which dig for and retrieve even more information than what we’re used to, benefit someone in a window of opportunity, where choices made today could turn around or reverse a future health condition? If they’re able to reach more people, possibly. 

“People are familiar with wearables, and we see biowearables as the next step in that technology,” said Marc Taub, divisional vice president of technical operations for Abbott’s diabetes care business. The devices can give people “insight into their bodies they never had before,” Taub said during a digital health panel at CES last week.

What are biosensors? 

Biosensors are a wearable you stick to a part of your body, like your arm, to lift health data using a tiny sensor. Continuous glucose monitors, or CGMs, for people with Type 1 diabetes have been the main product.

It’s official: Apple’s Find My network now lets you track twice as many devices

It’s official: Apple’s Find My network

now lets you track twice as many devices

source: techradar.com (contributed by FAN, Steve Page)  |  image: pixabay.com

Apple has quietly confirmed that it has doubled the number of devices that you can track in its Find My app. While no official announcement was made by Apple itself, the change was first reported by Nicolas Alveraz (@nicolas09F9) and shared in a post on X (formerly Twitter). 

In a support document published on January 11, Apple revealed that you can now add up to 32 items in Find My instead of the previous limit of 16 items. This includes AirTags, first-party headphones, selected Beats headphones, newer MagSafe wallets, and third-party accessories and gear such as e-bikes. 

It was confirmed by MacRumors that Apple increased the Find My item limit when iOS 16 and iPadOS 16 was launched in September 2022, but Apple never mentioned the change publicly until now. 

In the Apple document, it details that some AirPods will count as more than one item when paired to Find My. With the exception of the AirPods Max, regular AirPods and AirPods Pro (1st gen) count as two items, and the AirPods Pro (2nd gen) count as three items. With AirPods and the 1st gen AirPods Pros, users can track each AirPod individually, thus marking it as two items. When tracking 2nd gen AirPods Pros, you can use Find My to track the charging case, making it the third item. 

Apple introduced AirTags in 2021, making it easier for you to track your personal belongings as well as other Find My-compatible devices. However, avid Apple users voiced their concerns as they found themselves reaching the original 16-item limit quickly. This meant users would have to strategically decide which items to pair, which became increasingly difficult when Apple opened Find My pairing to third-party products shortly after. 

How to add an AirTag to your Find My network 

This now-official increase to the Find My device limit means that Apple super-users can track more devices and products without the fear of quickly reaching the limit. 

Not sure how to pair more products to your Find My network? Adding AirTags, for example, to the network is pretty easy. 

Hold your AirTag near your iPhone, and from there a pop up will appear on your screen for you to tap ‘Connect’. You’ll then have to name your AirTag from the options that appear in the scrolling list and tap ‘Continue’. 

Once you’ve tapped ‘Continue’ again, register your AirTag with your Apple ID by tapping ‘Done’.

How to Be More Anonymous Online

Being fully anonymous is next to impossible—but you can significantly limit what the internet knows about you by sticking to a few basic rules.

 

On the internet, everyone wants to know who you are. Websites are constantly asking for your email address or trying to place tracking cookies on your devices. A murky slurry of advertisers and tech firms track which websites you visit, predicting what your interests are and what you may want to buy. Search engines, browsers, and apps can log each search or scroll you make.

At this stage of the internet, being totally anonymous across your entire online life is incredibly hard to achieve. Phones, SIM cards, browsers, Wi-Fi networks, and more use identifiers that can be linked to your activity. But there are steps you can take to obscure your identity for everyday browsing.

If you’re looking to be truly anonymous or to protect your identity for a specific purpose—such as whistleblowing or activism—you should consider your threat model and individual security situation. But many of the changes you can make, which are listed below, are straightforward switches that can stop you from being tracked as much and apply to most people.
