Decoding Favoritism: How Parents Shape Sibling Bonds

New research sheds light on how parents subtly favor children based on birth order, personality, and gender, shaping family dynamics. Younger siblings often receive more favorable treatment, while older siblings are granted greater autonomy.

Delayed Brain Maturation Links Genetics and Eating Disorders

Over half of 23-year-olds display restrictive, emotional, or uncontrolled eating behaviors, with delayed brain maturation playing a significant role. The research linked structural brain differences, mental health challenges, and genetic predispositions to the development of disordered eating behaviors from adolescence to adulthood. MRI data showed delayed cortical thinning in unhealthy eaters, especially in regions like the cerebellum, which regulates appetite.

Physical Neglect Causes Lifelong Social Challenges in Children

A new study highlights how childhood physical neglect disrupts social development more than physical, emotional, or sexual abuse. Neglected children were less social, less popular, and less connected to cohesive friend groups, facing stigmatization and withdrawal.

Neural Mechanisms Behind Stress-Driven Social Changes Found

Male and female mice usually prefer female companions but switch to preferring males under survival stress, a new study reveals. This behavioral shift is driven by distinct brain circuits involving dopaminergic neurons in the ventral tegmental area.

High-Fat Diets in Adolescence Linked to Adult Impulsivity

Adolescent rats fed a high-fat diet displayed increased impulsivity and altered decision-making as adults. These "cheesecake rats" were quicker to act on visual cues (indicative of impulsivity) but showed more conservative choices in gambling tasks, opting for smaller, safer rewards.

How We Make Life’s Toughest Choices

A new study presents a novel framework for understanding transformative life decisions, focusing on their complexity and emotional impact. Researchers identified five key dimensions—conflicting cues, change of self, uncertain experiential value, irreversibility, and risk—that shape these decisions.

Early Reproductive Aging Alters Brain Connectivity, Emotional Health

Research shows that accelerated reproductive ageing in females, such as early puberty or menopause, is linked to increased mental health risks at different life stages. Adolescents experiencing early puberty displayed unstable brain connectivity in regions tied to psychosis vulnerability, while middle-aged women with early menopause showed patterns linked to depression.

Over Half of College Students Affected by Others’ Drinking

Over half of U.S. college students experience harm caused by others' drinking, highlighting the widespread impact of alcohol misuse on campuses. These harms range from babysitting intoxicated peers to experiencing verbal abuse, emotional distress, or even physical assaults.

Emotional News Alters Men’s Financial Choices

New research reveals that men are more likely than women to let emotions from unrelated situations affect their financial decisions. After watching emotional news stories, men opted for safer financial choices, while women’s decisions remained unchanged.

False Memories Are Harder to Create Than Once Thought

A new analysis challenges long-standing claims about the ease of implanting false memories, often cited in court cases to discredit witnesses. Researchers re-evaluated data from a 2023 replication of the "Lost in the Mall" study, finding that none of the participants formed fully false memories of a fabricated childhood event.

“Sandwich” Generation Face Health Toll of Caring for Parents and Kids

Sandwich carers—those who care for both children and aging relatives—face significant mental and physical health declines, particularly when caregiving exceeds 20 hours weekly. A study tracking carers over nine years found persistent mental health challenges and worsening physical health during this transition.

Social Connections Key to Borderline Personality Disorder Therapy

Loneliness plays a central role in borderline personality disorder (BPD) and often persists even when clinical symptoms subside. Current treatments, such as dialectical behavior therapy, fail to fully address social integration, which is crucial for long-term recovery.
