People with psychopathic traits fail to learn from painful outcomes
A recent study published in Communications Psychology reveals that individuals with higher psychopathic traits show reduced sensitivity to pain, which affects their ability to learn from painful consequences. The researchers found that people with elevated psychopathic traits tend to revert quickly to initial beliefs after experiencing pain. This new insight could help us understand why individuals with these traits often struggle to adapt their behavior despite negative consequences.
People with psychopathic traits frequently ignore the negative consequences of their actions, likely due to differences in how they process punishment. Past studies have indicated that psychopathy is associated with both an insensitivity to punishment and an excessive drive toward reward, but this study aimed to explore the computational learning processes specifically related to pain. Pain can serve as a powerful teaching signal, so understanding how reduced pain sensitivity influences learning in people with psychopathic traits could shed light on the mechanisms behind their often harmful decision-making.
“One of the hallmarks of psychopathy is aggressive, exploitative behavior with little regard for the wellbeing of others,” said study author Dimana Atanassova, a postdoctoral researcher at the Donders Institute for Brain, Cognition and Behaviour at Radboud University.

Computer simulations reveal how cells break down the endoplasmic reticulum
Inside cells, there exists an extensive system of canals known as the endoplasmic reticulum (ER), which consists of membrane-encased tubes that are partially broken down as needed—for instance in case of a nutrient deficiency. As part of this process, bulges or protrusions form in the membrane, which then pinch off and are recycled by the cell.
New ‘gold-plated’ superconductor could be the foundation for massively scaled-up quantum computers in the future
The interface superconductor underwent a transition under a magnetic field and became more robust, the scientists said in the paper This suggests it has transformed into a “triplet superconductor.” — a type of superconductor that is more resistant to magnetic fields than conventional superconductors.
They conducted the research in conjunction with the National Institute of Standards and Technology. In earlier work, they demonstrated that thin films of gold and niobium naturally suppress decoherence — the loss of quantum properties due to external environmental interference.
Given its robust quantum qualities and its ability to suppress decoherence, this new superconducting material promises to be ideal for use in quantum computers, the scientists said. Minimizing decoherence within the system is a key challenge, which necessitates extreme measures to isolate the quantum computer from external influences, such as shifts in temperature or electromagnetic interference, as well as the use of error-correcting algorithms to ensure calculations remain accurate.
Creating compact near-sensor computing chips via 3D integration of 2D materials
Polyethylene (PE) is one of the most widely used and versatile plastic materials globally, prized for its cost-effectiveness, lightweight properties and ease of formability. These characteristics make PE indispensable across a broad spectrum of applications, from packaging materials to structural plastics.
Could Data Be Stored in Plastic? Here’s How It Works
A new technique enables data storage in synthetic polymers, allowing direct bit access without full sequence decoding, significantly increasing storage density and stability, demonstrated by encoding a university address in ASCII within a polymer.
The need for data storage is growing, with many types of data requiring long-term preservation. Synthetic polymers present an efficient alternative to traditional storage media, as they can store information using less space and energy. However, conventional retrieval methods, like mass spectrometry, limit the length—and therefore the storage capacity—of individual polymer chains. Now, as reported in Angewandte Chemie, researchers have developed a new approach that overcomes this limitation, enabling direct access to specific data bits without having to read the entire chain.
