A senolytic (from the words senescence and -lytic, "destroying") is among a class of small molecules under basic research to determine if they can selectively induce death of senescent cells and improve health in humans. [1] A goal of this research is to discover or develop agents to delay, prevent, alleviate, or reverse age-related diseases.
This category lists some of the species that have become extinct due to human activity, whether intentionally or unintentionally. If a more specific reason is known, the species should also be assigned to a subcategory of Category:Species by threat. They may also need to be placed in Category:Extinctions since 1500.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
This disease attacks humans early in life. Thus humans who are resistant enjoy a higher chance of surviving and reproducing. While humans have evolved multiple defenses against malaria, sickle cell anemia—a condition in which red blood cells are deformed into sickle shapes, thereby restricting blood flow—is perhaps the best known. Sickle ...
Closely related species should have similar antigens and therefore weaker immunological response to each other's antigens. The immunological response of a species to its own antigens (e.g. human to human) was set to be 1. The ID between humans and gorillas was determined to be 1.09, that between humans and chimpanzees was determined as 1.14.
Global surface temperatures rose to between 1.45°C and 1.6°C higher than the average from 1850 to 1900, making 2024 the hottest year in human history. #16 Firenado!!!! Chillicothe, Missouri
The hominoids are descendants of a common ancestor.. Homo sapiens is a distinct species of the hominid family of primates, which also includes all the great apes. [1] Over their evolutionary history, humans gradually developed traits such as bipedalism, dexterity, and complex language, [2] as well as interbreeding with other hominins (a tribe of the African hominid subfamily), [3] indicating ...
The theory of animal-to-human transplants, known as xenotransplantation, dates back hundreds of years. Only recently, though, has that goal appeared to be within reach. Only recently, though, has ...
