A cray-active solution for cancer research

… causes, which makes the marbled crayfish an interesting model for cancer research. Frank Lyko, scientist at the German Cancer Research Center (DKFZ) in Heidelberg has a keen interest in epigenetics. Unlike genetics where a fault in the genetic makeup will cause a gene to deliver the wrong product, occur multiple times or be missing completely, epigenetics is concerned with tiny changes in the genetic material which cause a gene to be more or less active. This is crucial for organisms to adapt to …

Fossils suggest animals and not a meteorite wiped out planet’s first ‘Ediacarans’ microbes | Daily Mail Online

… study says Mass extinctions are usually blamed on rapid events, such as meteorite impacts and volcanic super-eruptions. But the world’s first known mass extinction – which took place about 540 million years ago – was caused by something far more slow-moving: evolution. A new study has found that Earth’s earliest microbes were wiped out by the evolution of complex life. ‘People have been slow to recognise that biological organisms can also drive mass extinction,’ …

… unprecedented in human history and highly unusual in Earth’s history,” the report says. “Our global society has started to destroy species of other organisms at an accelerating rate, initiating a mass extinction episode unparalleled for 65 million years.” “The broad definition that’s usually offered for a mass extinction is an event that wipes out a large portion of the world’s biota, across many different groups of organisms and across many parts of the world,” says Elizabeth …
