Butterfly effect and autism spectrum disorder

A study conducted by researchers at the RIKEN Center for Brain Science (CBS) has shed light on the genetics of Autism Spectrum Disorder (ASD). They found that a particular type of genetic mutation contributes to ASD differently than typical mutations. By analyzing mutations in the genomes of individuals and their families, the researchers discovered that the three-dimensional structure of the genome can cause mutations to affect neighboring genes associated with ASD, even without mutations in ASD-related genes. The study was published in the scientific journal Cell Genomics on January 26. ASD is a group of conditions characterized by repetitive behaviors and social interaction difficulties. Although the condition runs in families, its heritability is complex and only partially understood. According to studies, the high heritability cannot be explained by merely looking at the part of the genome responsible for protein coding. Instead, the answer could lie in the non-coding regions of t...

Boy With 5 Chambered Heart

The doctors of the cardiological center in the Kemerovo region were shocked when they made ultrasonic examination and saw the heart of a newborn baby Vanya Maryin. He was born with a 5-chamber heart. Only bees have such heart constitution. Funny enough the ‘bee-boy’, as doctors called him, comes from the beekeeper’s family. The family remembers a wonderful inherited bee yard that Vanya’s grandfather held, and his wife that ran the ‘bee-business’ after his death. Her bees produced the best honey in the district. Vanya was born not with 2 atriums like all the people on the Earth, but with an additional - third one. He could die anytime from a sudden push, fright or even happiness. But the body, adjusting to an unusual 5-chamber ‘bee-heart’, suggested the boy a saving, optimal ‘pose for life’. Another interesting read related to this story ‘The boy’s heart had 5 chambers instead of 4. Usually the heart consists of the right atrium and the right ventricle, the left atrium and the left ...

Rethinking Cannabis: Unlocking the Genetic Blueprint of an Ancient Powerhouse

Cannabis has played a critical role in human societies for over ten millennia. Although contemporary attention often centers on its psychoactive component, THC (tetrahydrocannabinol), historically this plant served as an essential source of seed oil, textiles, and nourishment. Despite its longstanding significance, cannabis remains relatively underexplored and underexploited in modern agriculture. Recent legislative changes in the United States—most notably the 2014 and 2018 Farm Bills—have spurred renewed interest in cultivating cannabis for medicinal, grain, and fiber purposes. A team at the Salk Institute has now produced the most exhaustive and precise genetic atlas of cannabis to date. By examining 193 distinct cannabis genomes, researchers uncovered remarkable genetic diversity and complexity within this foundational crop. This collaborative effort involved Oregon CBD, Oregon State University, and the HudsonAlpha Institute for Biotechnology, and culminated in findings published i...

Understanding the Complex Interplay: Dementia and Genetic Changes

Introduction: Dementia is a challenging and multifaceted condition that affects millions of individuals worldwide. As our understanding of the factors contributing to dementia expands, one crucial aspect gaining attention is the role of genetic changes. This blog post aims to explore the intricate relationship between dementia and genetic factors, shedding light on the complexities of this neurological disorder. I. The Genetic Landscape of Dementia: Dementia encompasses a range of cognitive disorders, with Alzheimer's disease being the most prevalent form. While environmental factors and lifestyle choices play a role in dementia development, genetic changes are increasingly recognized as significant contributors. A. Familial Patterns: Research has identified certain familial patterns in dementia, indicating a genetic predisposition for some individuals. Families with a history of dementia may carry specific gene variants that increase the risk of developing the condition. Understan...

Unraveling the Mysteries: Exploring New Genetic Variants Related to Dementia

Introduction: Dementia, a debilitating condition affecting millions worldwide, has long been a subject of intense research. Scientists and researchers have tirelessly worked towards understanding its underlying causes, and recent breakthroughs in genetics have brought forth new hope. This blog post delves into the latest discoveries surrounding genetic variants linked to dementia, shedding light on the potential implications for both diagnosis and treatment. The Human Genome Project and Beyond: Advancements in genetic research, particularly since the completion of the Human Genome Project, have paved the way for a deeper understanding of the intricate relationship between genes and various health conditions, including dementia. The identification of specific genetic variants associated with an increased risk of developing dementia has become a pivotal focus. Key Genetic Variants: Recent studies have unveiled several genetic variants implicated in the onset and progression of dementia. ...
