Does anyone still remember the initial phase of the Corona pandemic in 2020? When shops, restaurants, cinemas, and theatres remained closed. When meetings with friends and relatives were prohibited. When school lessons had to take place at home in the children's rooms. When there was no question of traveling.

Presently, most people seem to have long forgotten these times. Yet, the various corona measures taken by politicians are likely to have caused enormous stress for many. The fear for the job, the worry about sick relatives, the nervous strain when parents and children sit together in a small apartment and have to reconcile home office and homeschooling: All this has not remained without effects, as numerous studies show. The crucial factor is anxiety

How and to what extent have these experiences affected the mental health and quality of life of women and men in the first year of the COVID-19 pandemic? This has been investigated by a research team of the University and the University Hospital Würzburg.

In detail, the scientists were interested in the relationship between worries about the workplace and about other people with a person's own mental health problems such as anxiety and depression and with their quality of life in general, how these are influenced by the support from friends or at work – and whether the results show differences between men and women.

The findings are unambiguous: in this complex of different variables and influencing factors, anxiety plays a central part. There are, however, distinct gender-specific differences: In men, anxiety increases along with concerns about the job, an effect which does not show in women. On the other hand, we were able to register an increase in anxiety levels in women parallel to an increase in their worries about family and friends."

In addition, the study shows that women in such times respond positively to support from friends and family by experiencing enhanced quality of life. In men, this phenomenon did not manifest itself. Data on the influence of gender were lacking

Grit Hein is Professor of Translational Social Neuroscience at the Clinic and Polyclinic for Psychiatry, Psychosomatics and Psychotherapy at the University Hospital. She and her postdoc Martin Weiβ led the study, the results of which have now been published in the journal Scientific Reports.

"In the past, numerous studies have investigated the influence of psychosocial factors such as support from friends and colleagues and financial, professional or personal worries on mental health and the quality of life. Yet, data on whether these correlations are the same for men and women were lacking," says Grit Hein, explaining the background to the study. Broadening earlier studies, the Würzburg research team has therefore now examined the influence of these factors in relation to gender. A study with around 2,900 participants

The team obtained the relevant information from a large group of test subjects: the participants of the so-called STAAB study. This study comprises a cohort of around 5,000 randomly selected volunteers from the general population of Würzburg and originally focused on the development of cardiovascular diseases. During the COVID-19 pandemic, the program was spontaneously expanded to include the psychosocial impacts of the pandemic, the lockdown, and other side effects.

A total of 2,890 people (1,520 women and 1,370 men) took part in the survey. Their ages ranged from 34 to 85 years, with a median of 60 years. Between June and October 2020, they had to fill out an extensive questionnaire about their mental health. Among other things, they were asked to provide information about how strongly they felt supported by their social environment, their colleagues and superiors, and whether they had someone with whom they could discuss their problems.

They were also asked to what extent bans on the contact with parents and grandparents burdened them and how much stress they felt at work or at school. Financial problems or worries about them were the subject of further questions.

To evaluate the data, Hein and her team used a special method: the so-called network analysis. "Analyses based on a network approach enable a graphical representation of all variables as individual nodes," Hein explains. Thus, it is possible to identify variables that are particularly related to other variables. The network can, for example, show complex relationships between symptoms of different mental disorders and thus explain possible comorbidities. Results fit traditional gender norms

Grit Hein and Martin Weiβ were hardly surprised by the results. "The observation that men are more strongly associated with work and women more strongly with family and friends can be traced back to traditional gender norms and roles," Hein explains. Hence, men usually feel more affected by job insecurity and unemployment, which leads to higher psychological stress. Women, on the other hand, experience more strain when they feel that they are neglecting their family.

It is also plausible that women cope better psychologically when they receive support from friends and family: "This is in line with the traditional female family role, which includes a stronger tendency to maintain close social contacts and to seek social support in order to reduce stress and increase well-being," says Hein.

Even though these findings are unambiguous, the study leaders point to a number of limitations. The most important: "Since the COVID-19 pandemic presented a very specific context, it remains to be clarified whether our results are transferable to general pandemic-independent situations." One finding, however, is indisputable: "Our results underline the need to consider social aspects in therapeutic interventions in order to improve the mental health of women and men." Source:

'Dangerous proposition': Top scientists warn of out-of-control AI

Yoshua Bengio (L) and Max Tegmark (R) discuss the development of artificial general intelligence during a live podcast recording of CNBC’s “Beyond The Valley” in Davos, Switzerland in January 2025.

CNBC

Artificial general intelligence built like “agents” could prove dangerous as its creators might lose control of the system, two of of the world’s most prominent AI scientists told CNBC.

In the latest episode of CNBC’s “Beyond The Valley” podcast released on Tuesday, Max Tegmark, a professor at the Massachusetts Institute of Technology and the President of the Future of Life Institute, and Yoshua Bengio, dubbed one of the “godfathers of AI” and a professor at the Université de Montréal, spoke about their concerns about artificial general intelligence, or AGI. The term broadly refers to AI systems that are smarter than humans.

Their fears stem from the world’s biggest firms now talking about “AI agents” or “agentic AI” — which companies claim will allow AI chatbots to act like assistants or agents and assist in work and everyday life. Industry estimates vary on when AGI will come into existence.

With that concept comes the idea that AI systems could have some “agency” and thoughts of their own, according to Bengio.

“Researchers in AI have been inspired by human intelligence to build machine intelligence, and, in humans, there’s a mix of both the ability to understand the world like pure intelligence and the agentic behavior, meaning … to use your knowledge to achieve goals,” Bengio told CNBC’s “Beyond The Valley.”

“Right now, this is how we’re building AGI: we are trying to make them agents that understand a lot about the world, and then can act accordingly. But this is actually a very dangerous proposition.”

Bengio added that pursuing this approach would be like “creating a new species or a new intelligent entity on this planet” and “not knowing if they’re going to behave in ways that agree with our needs.”

“So instead, we can consider, what are the scenarios in which things go badly and they all rely on agency? In other words, it is because the AI has its own goals that we could be in trouble.”

The idea of self-preservation could also kick in, as AI gets even smarter, Bengio said.

“Do we want to be in competition with entities that are smarter than us? It’s not a very reassuring gamble, right? So we have to understand how self-preservation can emerge as a goal in AI.”

AI tools the key

For MIT’s Tegmark, the key lies in so-called “tool AI” — systems that are created for a specific, narrowly-defined purpose, but that don’t have to be agents.

Tegmark said a tool AI could be a system that tells you how to cure cancer, or something that possesses “some agency” like a self-driving car “where you can prove or get some really high, really reliable guarantees that you’re still going to be able to control it.”

“I think, on an optimistic note here, we can have almost everything that we’re excited about with AI … if we simply insist on having some basic safety standards before people can sell powerful AI systems,” Tegmark said.

“They have to demonstrate that we can keep them under control. Then the industry will innovate rapidly to figure out how to do that better.”

Tegmark’s Future of Life Institute in 2023 called for a pause to the development of AI systems that can compete with human-level intelligence. While that has not happened, Tegmark said people are talking about the topic, and now it is time to take action to figure out how to put guardrails in place to control AGI.

“So at least now a lot of people are talking the talk. We have to see if we can get them to walk the walk,” Tegmark told CNBC’s “Beyond The Valley.”

“It’s clearly insane for us humans to build something way smarter than us before we figured out how to control it.”

There are several views on when AGI will arrive, partly driven by varying definitions.

OpenAI CEO Sam Altman said his company knows how to build AGI and said it will arrive sooner than people think, though he downplayed the impact of the technology.

“My guess is we will hit AGI sooner than most people in the world think and it will matter much less,” Altman said in December.

There's finally(!) an automatic fix to restart failed EV charging sessions

The ChargeX Consortium has figured out how to automatically restart failed EV charging sessions at fast chargers so drivers don’t have to.

Every EV driver has been there. You plug in, walk away to grab food or run errands, and expect your battery to be juicing up at a DC fast charger, only to return and realize nothing happened. Maybe the session failed, or maybe the charger glitched. Either way, you’re stuck unplugging, plugging back in, and now it’s going to take twice as long to charge.

The ChargeX Consortium (National Charging Experience Consortium), which is made up of researchers from the National Renewable Energy Laboratory (NREL), Idaho National Laboratory (INL), and Argonne National Laboratory (ANL), along with industry stakeholders, has come up with a smart fix for one of the most frustrating parts of public EV charging: failed sessions.

Its new report highlights the benefits of what it calls “seamless retry” – a hands-free tech solution that automatically restarts failed charging attempts. In other words, the driver no longer needs to physically unplug and replug the charging connector when a charging session fails.

The consortium’s new tech is designed specifically for DC fast charging. The “novel mechanism” automatically resets both the EV and the charger, then restarts the session in the background, so drivers don’t have to return to the car – or even have to think about it.

Ed Watt, a researcher at NREL and lead author of the “Recommended Practice Seamless Retry for Electric Vehicle Charging” report, said, “With a seamless retry mechanism in place, an EV driver at a retail center can plug in a charging connector, provide user input data, leave to shop, and feel confident that they will return to a charged vehicle.” (Click on the report link to see the specifics of how the novel mechanism works.)

The researchers didn’t just focus on the perks of seamless retry – they also looked at potential downsides. One concern was the extra time it might take for the system to restart a failed session, which could leave drivers frustrated. To tackle that, the consortium suggests that the EV industry provide transparency in the form of real-time status updates, insights into what went wrong, and recommendations based on the type of charging failure and number of attempts made.

Going forward, as the user experience becomes clearer, more work will fine-tune seamless retry. The ChargeX Consortium will keep refining the system – developing smarter, more targeted retry methods, ironing out implementation details, and running verification tests to make sure everything works seamlessly in the real world.
