(Press-News.org) As our society becomes more digital and interconnected, the systems that keep it running face growing vulnerability to cyber threats. Bahaa Eltahawy’s doctoral dissertation at the University of Vaasa, Finland, shows that safeguarding these networks requires a holistic approach.
From power grids and transport to healthcare systems, the functioning of modern society relies on interconnected networks. When these systems fail, the consequences ripple quickly across sectors. In his doctoral dissertation in Computer Science, Bahaa Eltahawy argues that ensuring their security is not just a technical challenge but a societal necessity requiring coordination between technology, governance, and human behaviour.
– Digitalisation has created vast interconnections between systems that were once isolated. The danger lies in cascading effects, where a failure in one sector triggers a collapse in others, causing widespread disruption across society. In two or three days, we’re gonna find ourselves living like it’s the Stone Age, Eltahawy notes.
Cybersecurity, cyberprivacy, and smart grid operations have been studied extensively, but often as separate domains. To address this fragmentation, the dissertation provides a model that expands protection into seven domains, including data governance, socio-technical factors, and risk analysis.
– When protection is viewed from only one angle, new problems inevitably emerge from another. We need experts from different disciplines to complement each other's knowledge, Eltahawy points out.
Protection is a continuous process, not a one-time fix
The study also reveals that many existing standards, such as those governing data protection, cybersecurity frameworks, and smart grid architecture, have limitations that prevent them from addressing cross-sectoral risks. By analysing the weaknesses of these standards, Eltahawy’s work shows where gaps exist and how coordinated strategies can strengthen resilience.
Ultimately, Eltahawy emphasises that critical infrastructure protection is a shared responsibility that requires cooperation between technical experts, managers, and decision-makers.
– Once we believe our systems are safe, that is when they start to weaken. Protection is a continuous and adaptive process that must evolve alongside new risks and technologies, explains Eltahawy.

Probing new mechanisms of depression and anxiety
2025-11-24
In a new JNeurosci paper, Tian-Ming Gao and colleagues, from Southern Medical University, explored how adenosine triphosphate (ATP) signaling relates to depression and anxiety using male mice. ATP is a molecule that not only provides energy but also supports communication between neurons. The researchers focused on ATP signaling in a brain region implicated in depression called the hippocampus.
Male mice that were more likely to acquire depressive- and anxiety-like symptoms following long-term stress had less ATP levels and ...
What can psychedelics teach us about the sense of self?
2025-11-24
When people use a psychedelic called dimethyltryptamine (DMT), they experience a temporary loss of their sense of self. DMT interacts with a frequency of brain activity associated with self-referential processes (alpha waves), but it’s unclear how this activity relates to self-awareness. Christopher Timmerman, at University College London, and Marco Aqil, currently at the University of Miami, are among researchers who used DMT as a tool to explore the relationship between alpha waves and self-awareness.
As reported in their JNeurosci paper, the researchers discovered ...
An integrated monolithic synaptic device for C-tactile afferent perception and robot emotional interaction
2025-11-24
Human emotional interaction relies heavily on CT afferents—unmyelinated nerves in hairy skin that convert gentle tactile stimuli into affective states. For robots to engage in similar empathetic communication, existing tactile sensing technologies fall short: most rely on segregated "sensation-transmission-processing" modules, which cause latency accumulation and high energy consumption due to repeated analog-to-digital conversion. "Current neuromorphic devices for touch either lack low-threshold sensitivity or separate ...
‘Zap-and-freeze’ technique successfully used to watch human brain cell communication
2025-11-24
**EMBARGOED FOR RELEASE UNTIL NOV. 24 AT 12 NOON**
Researchers at Johns Hopkins Medicine say they have used a “zap-and-freeze” technology to watch hard-to-see brain cell communications in living brain tissue from mice and humans.
Findings from the new experiments, supported by the National Institutes of Health and published Nov. 24 in Neuron, could potentially help scientists find the root causes of nonheritable forms of Parkinson’s disease, the researchers say.
Sporadic cases of Parkinson’s disease account for most ...
Prebiotic in diet linked to less impulsivity in gambling rats with TBI
2025-11-24
COLUMBUS, Ohio – Using a prebiotic to influence bacterial activity in the gut after a traumatic brain injury may help reduce impulsive behavior, one of the common symptoms to follow a moderate blow to the head, a new study in rats suggests.
Following up on previous work showing a connection between negative changes to gut bacteria after a traumatic brain injury (TBI) and poor decision making, researchers at The Ohio State University are now exploring whether the gut problems may actually cause some long-term symptoms.
They found that adding the prebiotic galacto-oligosaccharide (GOS) to rat diets before and after ...
Gestational weight gain and pregnancy outcomes after GLP-1 receptor agonist discontinuation
2025-11-24
About The Study: In a cohort composed primarily of women with obesity, glucagon-like peptide-1 receptor agonist (GLP-1RA) use with subsequent pre-pregnancy or early pregnancy discontinuation was associated with more gestational weight gain and a higher risk of preterm delivery, gestational diabetes, and hypertensive disorders of pregnancy.

Increasing postpartum use of GLP-1 receptor agonists
2025-11-24
About The Study: Glucagon-like peptide 1 receptor agonists (GLP-1RAs) are increasingly used for postpartum weight loss since the introduction of semaglutide for weight loss in late 2022. Most users were overweight prior to pregnancy and only 23% had a documented diabetes diagnosis, suggesting that the primary indication for use was weight reduction.

Patients who discontinued GLP-1s had more weight gain, complications during pregnancy
2025-11-24
In a study led by researchers at Mass General Brigham, pregnant individuals who stopped taking popular weight loss GLP-1 medications before or early in their pregnancy tended to gain more weight and have higher risks of diabetes and hypertensive disorders during pregnancy, and experienced preterm delivery more so than people who had never taken GLP-1 drugs. The findings are published in JAMA.
“The use of glucagon-like peptide-1 receptor agonists—or GLP-1RAs—has increased dramatically, but recommendations suggest their discontinuation before pregnancy ...
Untreated sleep apnea raises risk of Parkinson’s, study finds
2025-11-24
New research reveals that people with untreated obstructive sleep apnea have a higher risk of developing Parkinson’s disease. However, they can significantly reduce the risk by improving the quality of their sleep by using continuous positive airway pressure, or CPAP.
The study, which published today in the journal JAMA Neurology, examined electronic health records covering more than 11 million U.S. military veterans who received care through the Department of Veterans Affairs between 1999 and 2022.
The research was led by Oregon Health & Science University ...
Prevalence, characteristics, and genetic architecture of avoidant/restrictive food intake phenotypes
2025-11-24
About The Study: This cohort study found that the prevalence of avoidant/restrictive food intake in the general pediatric population was substantial, and affected children had an associated elevated risk of developmental difficulties across multiple domains. The findings suggest a need for broad support interventions and advance understanding of the genetic underpinnings of avoidant/restrictive food intake.
