Making enemies isn’t random. Traits like emotional instability, aggression, and disruptive behavior early in life can lead to antagonistic relationships. Research on students aged 9-14 found that negative behaviors, such as lack of empathy, increase the likelihood of mutual antagonisms, a pattern seen across genders and school levels. Emotionally struggling students were 35% more likely to develop enemies, showing that how we manage emotions and interact with others early on can have lasting social and emotional effects.
A new definition of dyslexia is needed to more accurately describe the learning disorder and give those struggling with dyslexia the specific support they require, says new research.

The study, which examined the relationship between childhood exposure to trauma and vascular dysfunction among more than 400 Black adults in Atlanta ages 30 to 70, found that women who experienced childhood trauma had a worse vascular function, a preclinical marker of heart disease, while men had none. In addition, the findings indicated that women may be more vulnerable to a larger cumulative stress burden, eliciting varying physiological stress responses. Childhood trauma in women can cause arterial stiffness, or an impaired artery function of the cardiovascular system, contributing to major cardiac events, such as stroke and heart attack. It also contributes to heart disease, high blood pressure, and a malfunctioning small blood vessel system, which could damage tissues in the kidneys or brain.
Background: Chronic obstructive pulmonary disease (COPD) was a significant public health concern, with smoking being the primary risk factor for its development and progression. The impact of smoking on respiratory rehabilitation efficacy in COPD patients remains an area of interest and investigation. This study aimed to assess the influence of smoking on the efficacy of respiratory rehabilitation in patients with COPD.
Methods: Data of patients with COPD from October 2015 to October 2023 were retrospectively analyzed in this case-control study. The patients who had previously participated in a pulmonary rehabilitation program were excluded. Pulmonary function, exercise capacity, quality of life, and sleep patterns were evaluated before and after rehabilitation.
Results: A total of 40 patients were included and categorized into non-smoking (n=20) and smoking groups (n=20) based on their smoking history. Before rehabilitation, no significant differences were observed between the groups in forced expiratory volume in one second (FEV1) (P=0.96), forced vital capacity (FVC) (P=0.97), FEV1/FVC ratio (P=0.73), maximal voluntary ventilation (MVV) (P=0.69), and diffusing capacity of the lung for carbon monoxide (DLCO) (P=0.63). After rehabilitation, FEV1 (P=0.02), FVC (P=0.009), FEV1/FVC ratio (P=0.03), MVV (P=0.004), DLCO (P=0.01), these pulmonary functions for non-smokers were much better than the smokers. Similarly, the non-smoking group exhibited significantly greater improvements in 6-minute walk distance (P=0.03), peak oxygen consumption (VO2) (P=0.01), Borg scale ratings (P=0.02), St. George’s Respiratory Questionnaire (SGRQ) scores (P=0.004), and Medical Research Council (MRC) dyspnea scale scores (P=0.005) compared to the smoking group after rehabilitation. The non-smoking patients have more better quality of life compared to the smokers after rehabilitation, which demonstrated by the quality of life scores and Sleep Quality Score, including somatization (P=0.01), emotion management (P=0.009), role play (P=0.008), cognitive function (P=0.04), return to social function (P=0.01), Sleep Quality Score (P=0.02).
Conclusions: Smoking negatively impacts the efficacy of respiratory rehabilitation in COPD patients, leading to poorer pulmonary function, exercise capacity, quality of life, and sleep patterns.
A new study by Prof. Shalva Weil from the Seymour Fox School of Education at the Hebrew University reveals that the unique Purim traditions of the Cochin Jewish community, particularly the use of effigies as symbols of resistance and social inversion, have disappeared following their migration to Israel. Once deeply embedded in their communal identity in India, these traditions faded as the community integrated into the broader global Jewish experience. While Cochin Jewry no longer exists as a significant presence in India beyond positive memories, their cultural legacy persists in Israel, albeit in a transformed and assimilated manner.
A study conducted at the University of Eastern Finland shows that long-term unemployed individuals perceive their capabilities as weaker than the general Finnish population. Capabilities refer to the opportunities to achieve important things in life, such as health and well-being. Additionally, the study found that long-term unemployed men perceive their capabilities as weaker than long-term unemployed women.
Primates scratch their skin or fur in a stressful situation (Figure 1). By using this self-scratching behaviour as a behavioural indicator of stress, our study on wild female Japanese macaques provided a novel and counter-intuitive finding: females exhibit higher stress levels when a closely related female is nearby. This pattern was found only during foraging but not resting, suggesting that food-related competition among relatives is a cause of their elevated stress. This unexpected finding provides new insight into the complex social dynamics of primates and their stress responses.
