Hormones Shape Love and Lust Differently in Male & Female Brains

New research uncovers how a hormonally tuned brain circuit in mice governs sex-specific mating behaviors. Scientists identified a subset of neurons in the prefrontal cortex that integrate oxytocin, ovarian hormones, and social cues to modulate sexual receptivity in females and suppress mating interest in males.

Cancer Drug Shows Promise In Treating AMD Vision Loss

Scientists have discovered that a locally developed cancer drug, PRL3-zumab, may offer a groundbreaking treatment for two major causes of blindness: wet age-related macular degeneration and diabetic retinopathy. Pre-clinical studies showed that intravenous PRL3-zumab reduced abnormal eye blood vessel leakage by 86% more than standard eye injections, with fewer risks.

Middle-Age Clues: Blood Biomarkers Signal Alzheimer’s Risk Early

New research shows that signs of Alzheimer’s disease can already be detected in the blood of people as young as their 40s. Finnish scientists found elevated Alzheimer’s-related biomarkers in middle-aged adults, especially among those with maternal history or kidney disease.

Friendship Synchronizes Brains

A new study reveals that close friendships can synchronize brain activity and influence decision-making, particularly in consumer behavior. Researchers found that friends evaluated products more similarly than strangers, with this effect strengthening as friendships deepened.

Common Sweetener May Raise Stroke Risk by Altering Brain Cells

A common sugar substitute, erythritol, widely used in “sugar-free” and low-carb products, may increase stroke risk by damaging brain blood vessel cells. A new study found that erythritol exposure reduced nitric oxide, increased vessel constrictors, impaired clot-busting abilities, and boosted free radical production in these cells.

Why Women Face Higher Alzheimer’s Risk

Women are nearly twice as likely as men to develop Alzheimer’s disease, a disparity that can’t be fully explained by longevity alone. Researchers are exploring biological differences, focusing on X chromosome-linked genes and hormonal shifts like menopause.

Blood Sugar, Not Age, Drives Sexual Health Decline in Men

A new study reveals that metabolic health, particularly modest increases in blood sugar, plays a bigger role than age or testosterone in declining sexual and reproductive function in men. Researchers tracked 117 healthy men over six years, assessing hormones, semen quality, erectile function, and blood sugar.

Oxytocin Protects Mood During Sleep Loss

New research suggests oxytocin, the so-called “love hormone,” may help protect women from mood disturbances caused by sleep disruption and hormonal changes during postpartum and menopause. In a controlled study, women with higher oxytocin levels before sleep fragmentation reported fewer mood symptoms the following day.

Weekly Injection Could Revolutionize Parkinson’s Treatment

Researchers have developed a long-acting weekly injection that delivers steady doses of levodopa and carbidopa, potentially transforming care for Parkinson’s disease. The biodegradable injectable maintains consistent drug levels, reducing the need for multiple daily pills and improving patient adherence.

Gene Key to MS Immune Regulation Discovered

New research has identified the gene Egr-1 as a critical regulator of immune balance, offering hope for autoimmune disease therapies. In a mouse model of multiple sclerosis, loss of Egr-1 led to reduced regulatory T cell activity and heightened inflammation. T

Maternal Depression Linked to Weaker Bonds

A comprehensive global review confirms that maternal depression undermines parenting, impairing mother-infant bonding and reducing sensitivity to a child’s needs. Researchers analyzed nearly a decade of observational studies, finding consistent links between depressive symptoms and lower involvement, commitment, and emotional connection.

Study Challenges Link Between Football and Brain Protein Buildup

A new study questions whether playing youth football leads to harmful protein buildup in the brain. Researchers examined 174 donated brains, including former high school and college players, and found no link between contact sports and excess tau protein in a key memory region.
