Why do some mammals live longer? The secret lies in brain size and immune system

The longevity of whales and other marine animals, especially those who made a transition from land to sea millions of years ago, has just been discovered and is precisely a step is associated with a slowing down of life as a result of developing certain capacities for their re-adaptation at sea. These animals, such as whales, have a slow pace of life and low fertility that make them very vulnerable to human impact in the form of pollution, clima…

Why do some mammals live longer? The secret lies in brain size and immune system

Have you ever wondered why cats tend to live longer than dogs, or why whales can live for over a century while mice barely make it past two years? New research led by scientists from the University of Bath suggests the answer may lie in their brains and immune systems. The study, published in Scientific […] The post Why do some mammals live longer? The secret lies in brain size and immune system appeared first on Knowridge Science Report.

Correlations Between Maximum Species Life Span, Brain Size, and Immune Function

Researchers interested in the comparative biology of aging have focused much of their efforts on the search for genetic differences that correlate with species life span. This can be higher or lower expression in directly homologous genes, but also differences in the number of genes in a family relating to a specific function, and differences in gene sequences. As one might expect, well established genetic differences involve genes associated wi…

Scientists discover what drives the maximum lifespan potential of mammals

Scientists have long wondered why some mammals live dramatically longer than others. While humans can reach ages beyond a century, certain whales surpass two centuries, and elephants easily live decades, some small mammals, like mice or shrews, barely survive a couple of years. The secret to these striking differences may lie hidden within the genes of mammals, and a new study sheds intriguing light on this evolutionary puzzle. The Secret in Mam…

Barcelona (Spain), 12 May (EFE).- Living in the sea requires a series of adaptations that improve the survival of individuals and therefore favor longevity points to a study by several scientific bodies of universities that sheds light on the mystery of the long life of whales and other marine animals. The research, published in the journal Nature Communications, has been coordinated by the Institute of Evolutionary Biology (IBE) and CREAF (Cent…

Whale observations in Latin America are possible in several countries, including Argentina, Chile Ecuador, Brazil, Belize, Peru, the Doiminican Republic and Mexico. Especially recommended are the peninsula Valdés in Argentina for South Cape Whales and Orcas. In Ecuador humpback whales can be observed in Salinas and around the Galapagos Islands. Brazil offers whale observations in Itacaré, Praia do Forte and in [...] The post Why Walurin is so im…
