Adult for a Mouse with Two Adult Kids
Summary: Researchers have successfully engineered bi-paternal mice, born from two male parents, that survived to adulthood using embryonic stem cell techniques. By modifying 20 key imprinting genes, they overcame the developmental barriers that previously limited unisexual reproduction in mammals.Though only 11.8% of embryos developed to term, the findings highlight imprinting

Important Memory Regions ‘ Head Exercise Is Reduced by Cannabis Use
Summary: A study of over 1,000 young adults reveals that both recent and heavy lifetime cannabis use reduce brain activity in regions critical for working memory, including the prefrontal cortex and anterior insula. This reduced activity correlates with poorer performance on memory tasks like following instructions or solving problems.While other

Synchronizing Nerve Stimulation With Heartbeat Boosts Effectiveness
Summary: Synchronizing vagus nerve stimulation with natural body rhythms, such as the heartbeat and breathing, significantly improves its effectiveness. This “electric pill” technique uses ear-mounted electrodes to stimulate the vagus nerve, targeting chronic conditions like pain and inflammation.Researchers found that stimulation during heart contraction (systole) and inhalation phases produced the

How the Brain Processes Space and Time
Summary: New research highlights a functional hierarchy in the brain’s processing of space and time. In posterior areas, like the occipital cortex, space and time are tightly linked and processed by the same neurons.In anterior regions, such as the frontal cortex, space and time are processed independently, with distinct neural

Dream Sleep Delays May Indicate Early Alzheimer’s
Summary: Delayed rapid eye movement (REM) sleep may be an early indicator of Alzheimer’s disease. Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.Delayed REM sleep disrupts memory consolidation and increases

Eating Disorders Cause Opioid Dysregulation in the Mind
Summary: Elevated opioid neurotransmission in the brain may underlie appetite loss and emotional symptoms in anorexia nervosa. Compared to healthy controls, patients with anorexia had increased opioidergic tone, which regulates appetite, pleasure, and mood.Despite severe malnutrition, glucose uptake in the brains of anorexia patients remained comparable to controls, suggesting the
