Body Illusion Helps Unlock Memories

Posted on by

A new study suggests that briefly changing the way people see their own bodies can make it easier to recall autobiographical memories, including some from early childhood.

Published in Scientific Reports, part of the Nature journal group, the research is the first to show that adults can access early memories more effectively after temporarily viewing themselves with a childlike version of their own face.

How the “Enfacement Illusion” Reconnects Mind and Body

Neuroscientists at Anglia Ruskin University (ARU) in Cambridge led the study, which involved 50 adult volunteers. The experiment used what is known as an “enfacement illusion,” a technique that helps people feel as though another face they see on a screen is actually their own reflection.

Each participant watched a live video of their own face that was digitally modified with an image filter to resemble how they might have looked as a child. As participants moved their heads, the on-screen image mirrored their movements, creating the sensation that the childlike face was truly theirs. A control group experienced the same setup but viewed their unaltered adult faces.

After completing the illusion, participants were asked to take part in an autobiographical memory interview designed to prompt recollections from both their early life and the previous year.

A Clear Boost in Childhood Memory Recall

Researchers measured how much detail participants included when describing their episodic autobiographical memories. These are the kinds of memories that allow a person to mentally relive past experiences and “travel back in time” within their own mind.

The findings revealed that people who saw the younger version of themselves remembered significantly more detailed events from childhood than those who saw their regular adult face. The results provide the first evidence that subtle changes in bodily self-perception can influence how deeply we access distant memories.

[…]

“All the events that we remember are not just experiences of the external world, but are also experiences of our body, which is always present.

“We discovered that temporary changes to the bodily self, specifically, embodying a childlike version of one’s own face, can significantly enhance access to childhood memories. This might be because the brain encodes bodily information as part of the details of an event. Reintroducing similar bodily cues may help us retrieve those memories, even decades later.”

Reimagining the Self to Revisit the Past

Senior author Professor Jane Aspell, head of the Self & Body Lab at Anglia Ruskin University, added: “When our childhood memories were formed, we had a different body. So we wondered: if we could help people experience aspects of that body again, could we help them recall their memories from that time?

“Our findings suggest that the bodily self and autobiographical memory are linked, as temporary changes to bodily experience can facilitate access to remote autobiographical memories.

Cavities could be prevented by a gel that restores tooth enamel

Posted on by

[…] developed a gel containing a modified version of a protein that they manipulated to act like amelogenin, a protein that helps guide the growth of our enamel when we are infants.

Experiments that involved pasting the gel onto human teeth under a microscope in solutions containing calcium and phosphate – the primary building blocks of enamel – show that it creates a thin and robust layer that stays on teeth for a few weeks, even during brushing.

The gel fills holes and cracks, creating a scaffold that uses the calcium and phosphate to promote the organised growth of new crystals in the enamel below the gel layer, even when so much was gone that the underlying dentine below was exposed.

“The gel was able to grow crystals epitaxially, which means it’s in the same crystallographic orientation as existing enamel,” says Mata.

That orientation means that the new growth – which reached up to 10 micrometres thick – is integrated into the underlying natural tissue, rebuilding the structure and properties of enamel. “The growth actually happens within a week,” says Mata. The process also worked when using donated saliva, which also naturally contains calcium and phosphate, rather than just in the solution the team used that comprised these chemicals.

A similar approach was reported in 2019, but that produced thinner coatings, and the recovery of the architecture of inner layers of enamel was only partial.

Clinical trials in people are set for early next year. Mata has also launched a company called Mintech-Bio and hopes to have a first product out towards the end of 2026, which he sees dentists using.

Ukraine First To Demo Open Source Security Platform To Help Secure Power Grid

Posted on by

[A massive power outage in April left tens of millions across Spain, Portugal, and parts of France without electricity for hours due to cascading grid failures, exposing how fragile and interconnected Europe’s energy infrastructure is. The incident, though not a cyberattack, reignited concerns about the vulnerability of aging, fragmented, and insecure operational technology systems that could be easily exploited in future cyber or ransomware attacks.] This headache is one the European Commission is focused on. It is funding several projects looking at making electric grids more resilient, such as the eFort framework being developed by cybersecurity researchers at the independent non-profit Netherlands Organisation for Applied Scientific Research (TNO) and the Delft University of Technology (TU Delft).

TNO’s SOARCA tool is the first ever open source security orchestration, automation and response (SOAR) platform designed to protect power plants by automating the orchestration of the response to physical attacks, as well as cyberattacks, on substations and the network, and the first country to demo it will be the Ukraine this year. At the moment, SOAR systems only exist for dedicated IT environments. The researchers’ design includes a SOAR system in each layer of the power station: the substation, the control room, the enterprise layer, the cloud, or the security operations centre (SOC), so that the SOC and the control room work together to detect anomalies in the network, whether it’s an attacker exploiting a vulnerability, a malicious device being plugged into a substation, or a physical attack like a missile hitting a substation. The idea is to be able to isolate potential problems and prevent lateral movement from one device to another or privilege escalation, so an attacker cannot go through the network to the central IT management system of the electricity grid. […]

The SOARCA tool is underpinned by CACAO Playbooks, an open source specification developed by the OASIS Open standards body and its members (which include lots of tech giants and US government agencies) to create standardized predefined, automated workflows that can detect intrusions and changes made by malicious actors, and then carry out a series of steps to protect the network and mitigate the attack. Experts largely agree the problem facing critical infrastructure is only worsening as years pass, and the more random Windows implementations that are added into the network, the wider the attack surface is. […] TNO’s Wolthuis said the energy industry is likely to be pushed soon to take action by regulators, particularly once the Network Code on Cybersecurity (NCCS), which lays out rules requiring cybersecurity risk assessments in the electricity sector, is formalized.

Music festivals to collect data with RFID wristbands. Also, randomly, fascinating information about data Flitsmeister collects.

Posted on by

This summer, Dutch music festivals will use RFID wristbands to collect visitor data. The technology has been around for a while, but the innovation lies in its application. The wristbands are anonymous by default, but users can activate them to participate in loyalty programs or unlock on-site experiences.Visitor privacy is paramount; overly invasive tracking is avoided.

This is according to Michael Guntenaar, Managing Director at Superstruct Digital Services, in the Emerce TV video ‘Data is the new headliner at dance festivals’. Superstruct is a network of approximately 80 large festivals (focused on experience and brand identity) spread across Europe and Australia. ID&T, known for events such as Sensation, Mysteryland, and Defqon.1, joined Superstruct in September 2021. Tula Daans, Data Analyst Brand Partnerships at ID&T, also joined on behalf of ID&T.

Festivals use various data sources, primarily ticket data (age, location, gender/gender identity), but also marketing data (social media), consumption data (food and drinks), and post-event surveys.

For brand partnerships, surveys are sent to visitors after the event to gauge whether they saw brands, what they thought of them, and thus gain insight into brand perception. Deliberately, no detailed feedback is requested during the festival to avoid disturbing the visitor experience, says Guntenaar.

The Netherlands is a global leader in data collection. Defqon.1 is mentioned as a breeding ground for experiments with data and technology, due to its technically advanced team and highly engaged target group.

[…]

In a second video, ‘Real-time mobility info in a complex data landscape’, Jorn de Vries, managing director at Flitsmeister, talks about mobility data and the challenges and opportunities within this market. The market for mobility data, which ranges from traffic flows to speed camera notifications, is busy with players like Garmin, Google, Waze, and TomTom.

Nevertheless, Flitsmeister still sees room for growth, because mobility is timeless and brings challenges, such as the desire to get from A to B quickly, efficiently, green, and cheaply. Innovation is essential to maintain a place in this market, says De Vries.

Flitsmeister has a large online community of almost 3 million monthly active users. This community has grown significantly over the years, even after introducing paid propositions. What distinguishes Flitsmeister from global players such as Google and Waze, according to De Vries, is their local embeddedness, with marketing and content that aligns with the language and use cases of users in the Benelux. They also collaborate with governments through partnerships, allowing them to offer specific local services, such as warnings for emergency services. Technically, competitors might be able to do this, says De Vries, but it probably isn’t a high priority because it’s local; Flitsmeister, however, believes that you have to dare to go all the way to properly serve a market, even if this requires investments that are only relevant for the Netherlands. Another example of local embeddedness is their presence on almost every radio station.

The Flitsmeister app now consists of eight main uses. In addition to the well-known speed cameras and track control, it includes warnings for emergency services (ambulance, fire brigade, Rijkswaterstaat vehicles) who are informed early when such a vehicle approaches with blue lights. The app also provides traffic jam information and warnings for incidents, stationary vehicles, and roadworks. Flitsmeister tries to give warnings for the start of traffic jams earlier than the flashing signs above the road, because they are not bound by the gantries where these signs are located.

Navigation is an added feature. In addition, there is paid parking at the end of the journey. Flitsmeister also has links with so-called smart traffic lights, where they receive data about the status of the light and share data with the intersection to optimize it. This can, for example, lead to a green light if you approach an intersection at night and there is no other traffic. More than 1500 smart intersections in the Netherlands are already equipped. Flitsmeister also receives data from matrix signs, including red crosses, arrows, and adjusted maximum speeds.

Privacy is a crucial topic when bringing consumers and data together. Flitsmeister has seen privacy from the start as a Unique Selling Point (USP) if handled correctly. Especially in countries like Germany, this is more active than in the Benelux, and privacy-friendly companies have a plus in the eyes of the consumer. Large players such as Google and Waze have the same legal playing field as Flitsmeister, but differ in what they want, can, and do.

Flitsmeister does collect live GPS data that provides a lot of insight into traffic movements. They are working with Rijkswaterstaat and their parent company Bmobile on pilots, including on the A9, where they combine loop data in the asphalt with their real-time data. This provides a more accurate and cost-efficient picture than road loops alone, which are expensive to maintain and measure limitedly. This combination allows them to provide relevant information, even between the road loops, leading to more accurate and cost-efficient traffic information.

Flitsmeister also works with data that detects real-time situations and provides early advice. They are doing pilots with ‘trigger based rerouting’, where users are proactively rerouted if a reported incident on their route is likely to affect their travel time, even if the travel time has not yet changed at that moment. The challenge here is that people must be receptive to this and understand the rationale behind the rerouting.

Although there is a lot of talk about connected vehicle data, Flitsmeister’s focus is more on strengthening the relationship with the driver than with the vehicle itself. Jorn de Vries believes that the driver will ultimately lead, as the need for mobility comes from the individual and the vehicle facilitates this.

The video Data is the new headliner at dance festivals can be watched for free. The collection Customer data: trends, innovation and future will be supplemented in the coming months and can be viewed for free after registration.

Symbolic Strength More Important Than Facts When It Comes To Misinformation

Posted on by

Why do some people endorse claims that can easily be disproved? It’s one thing to believe false information, but another to actively stick with something that’s obviously wrong.

Our new research, published in the Journal of Social Psychology, suggests that some people consider it a “win” to lean in to known falsehoods.

We are social psychologists who study political psychology and how people reason about reality. During the pandemic, we surveyed 5,535 people across eight countries to investigate why people believed COVID-19 misinformation, like false claims that 5G networks cause the virus.

The strongest predictor of whether someone believed in COVID-19-related misinformation and risks related to the vaccine was whether they viewed COVID-19 prevention efforts in terms of symbolic strength and weakness. In other words, this group focused on whether an action would make them appear to fend off or “give in” to untoward influence.

This factor outweighed how people felt about COVID-19 in general, their thinking style and even their political beliefs.

Our survey measured it on a scale of how much people agreed with sentences including “Following coronavirus prevention guidelines means you have backed down” and “Continuous coronavirus coverage in the media is a sign we are losing.” Our interpretation is that people who responded positively to these statements would feel they “win” by endorsing misinformation – doing so can show “the enemy” that it will not gain any ground over people’s views.

When meaning is symbolic, not factual

Rather than consider issues in light of actual facts, we suggest people with this mindset prioritize being independent from outside influence. It means you can justify espousing pretty much anything – the easier a statement is to disprove, the more of a power move it is to say it, as it symbolizes how far you’re willing to go.

When people think symbolically this way, the literal issue – here, fighting COVID-19 – is secondary to a psychological war over people’s minds. In the minds of those who think they’re engaged in them, psychological wars are waged over opinions and attitudes, and are won via control of belief and messaging. The U.S. government at various times has used the concept of psychological war to try to limit the influence of foreign powers, pushing people to think that literal battles are less important than psychological independence.

By that same token, vaccination, masking or other COVID-19 prevention efforts could be seen as a symbolic risk that could “weaken” one psychologically even if they provide literal physical benefits. If this seems like an extreme stance, it is – the majority of participants in our studies did not hold this mindset. But those who did were especially likely to also believe in misinformation.

In an additional study we ran that focused on attitudes around cryptocurrency, we measured whether people saw crypto investment in terms of signaling independence from traditional finance. These participants, who, like those in our COVID-19 study, prioritized a symbolic show of strength, were more likely to believe in other kinds of misinformation and conspiracies, too, such as that the government is concealing evidence of alien contact.

In all of our studies, this mindset was also strongly associated with authoritarian attitudes, including beliefs that some groups should dominate others and support for autocratic government. These links help explain why strongman leaders often use misinformation symbolically to impress and control a population.

Why people endorse misinformation

Our findings highlight the limits of countering misinformation directly, because for some people, literal truth is not the point.

For example, President Donald Trump incorrectly claimed in August 2025 that crime in Washington D.C. was at an all-time high, generating countless fact-checks of his premise and think pieces about his dissociation from reality.

But we believe that to someone with a symbolic mindset, debunkers merely demonstrate that they’re the ones reacting, and are therefore weak. The correct information is easily available, but is irrelevant to someone who prioritizes a symbolic show of strength. What matters is signaling one isn’t listening and won’t be swayed.

In fact, for symbolic thinkers, nearly any statement should be justifiable. The more outlandish or easily disproved something is, the more powerful one might seem when standing by it. Being an edgelord – a contrarian online provocateur – or outright lying can, in their own odd way, appear “authentic.”

Some people may also view their favorite dissembler’s claims as provocative trolling, but, given the link between this mindset and authoritarianism, they want those far-fetched claims acted on anyway. The deployment of National Guard troops to Washington, for example, can be the desired end goal, even if the offered justification is a transparent farce.

Is this really 5-D chess?

It is possible that symbolic, but not exactly true, beliefs have some downstream benefit, such as serving as negotiation tactics, loyalty tests, or a fake-it-till-you-make-it long game that somehow, eventually, becomes a reality. Political theorist Murray Edelman, known for his work on political symbolism, noted that politicians often prefer scoring symbolic points over delivering results – it’s easier. Leaders can offer symbolism when they have little tangible to provide.

Linux finally cracks 3% on Steam – 50% more users in 1 year. Maybe people are getting really really pissed at Microsoft.

Posted on by

In isolation, the numbers aren’t all that impressive. Linux usage is at 3.05 percent, up 0.37 percentage points from last month. However, it’s a significant uptick compared to the October 2024 results, which showed Linux usage at exactly two percent, up a mere 0.13 percentage points. It’s also up about 0.4 percentage points from the August survey numbers.

Yes, only a bit over one percentage point in a year – but compared to the total user numbers, that’s roughly a 50 percent jump. Adding half again to your market share in a year isn’t bad going. Keep this up and soon, you’re talking real mon— oh, wait, free software. Never mind.

Coupled with this is another bit of analysis of the Steam-on-Linux market from Linux gaming site Boiling Steam, which reported that by the end of October 2025, Windows games’ compatibility on Linux is at an all-time high. It buries the lede a little, but it gets there eventually:

the amount of games that refuse to launch is … getting very close to just 10%. This means that close to 90% of Windows games manage to launch on Linux.

Now, to be fair, just because a game launches doesn’t mean it runs well enough to play – it might start but still be unplayable for all sorts of reasons: being unusably slow, suffering from stutter or lag, showing graphics corruption, or constantly crashing. We’ve also read that some multiplayer games use anti-cheat measures that run at a low level and talk directly to the Windows OS – something emulation probably can’t fix in the foreseeable future. Even so, though, being able to run is a good start. It can be the point where a vendor starts troubleshooting what’s wrong, as opposed to telling customers something simply isn’t compatible.

This can’t simply be attributed to the Steam Deck. The Register reported on that way back in 2021, so it’s no longer new and shiny. There is other, newer SteamOS gadgetry, though. In January, Lenovo announced the first handheld officially licensed to ship with Valve’s SteamOS, the Lenovo Legion Go S. However, that officially went on sale back in May, so it’s a little too early to judge its impact.

It’s almost as if something happened earlier in October to make loads of people try out Linux. What an enduring mystery for the ages
