Discover the surprising truth about blood types: it’s far more complex than just A, B, AB, and O. Explore the intricacies of the ABO system, the Rh factor, and the hundreds of other antigens that determine the incredible diversity of human blood, impacting transfusions and health conditions.
Scientists have created Zebrahub, a groundbreaking atlas of zebrafish embryos that combines high-resolution timelapse videos with gene activity data. This incredible resource provides an unprecedented look into the earliest stages of life, revealing similarities across species and offering insights into human development, regeneration, and aging.
Scientists have identified genetic features in immune cells that may indicate the onset of multiple sclerosis (MS) years before symptoms appear. This discovery could lead to earlier diagnoses, more targeted treatments, and potentially prevent or delay the debilitating effects of the disease.
Obesity has reached epidemic proportions globally, driven by a complex interplay of dietary changes, sedentary lifestyles, environmental factors, genetics, and mental health. This article explores the key contributors to the rise of obesity and highlights the need for comprehensive strategies to address this pressing public health issue.
A new study challenges long-held beliefs about human migration during the last ice age. Genetic evidence suggests that some human populations remained in central Europe, defying the notion that our ancestors retreated to warmer southern regions. This study, which compared human genetic data with that of other mammals, reveals that humans, like wolves and bears, were surprisingly resilient to harsh glacial conditions.
While Charles Darwin believed evolution was a slow process, scientists now understand that evolution can happen much faster than previously thought, driven by factors like natural selection, environmental change, and human influence. This article explores the mechanisms and pace of evolution, highlighting how species adapt to changing conditions, even over short timescales.
New scientific evidence challenges long-held beliefs about when and where horses were first domesticated. The discovery of a new lineage of domestic horses and the reassessment of archaeological evidence points to a much later date for horse domestication than previously thought, impacting our understanding of early human societies and the spread of Indo-European languages and cultures.
A new study delves into the genetic history of a medieval Christian community in Spain who lived in artificial caves. Analyzing DNA from their remains revealed a story of inbreeding, violence, and disease, offering a unique perspective on life away from major urban centers during a tumultuous era.
Scientists are on the cusp of de-extinction, resurrecting extinct species like the woolly mammoth and dodo. While the technology is rapidly advancing, concerns about the ethical, ecological, and financial implications of this ambitious endeavor are mounting. This article explores the science behind de-extinction, examines its potential benefits and risks, and discusses whether this pursuit is ultimately worth the cost.
A vibrant pink, purple, and blue lobster, dubbed a ‘cotton candy’ lobster, was caught off the coast of New Hampshire. This incredibly rare find, estimated to occur at a rate of 1 in 100 million, is now on display at the Seacoast Science Center. The lobster’s unique coloration stems from a genetic mutation that disrupts the normal pigmentation process, resulting in a stunning display of hues.
