    Don’t worry about it though bud. Long before the sun’s light goes out, the structure of the stars break apart, all particles scatter, and the universe finally dies; you will die. The light in your eyes will extinguish, your bones and flesh will fall apart, and the atoms that make you will scatter throughout the earth.




  • In cases of cellular stress p53 is activated via phosphorylation. It will then direct the cell to pause its division and to either undergo DNA repair or kill itself. p53 is one of the body’s most important defences against cancer. Mutations causing p53 dysfunction are found in more than half of cancer cases.

    Anyone know what the first known case of ‘bug’ exclusively referring to Hemipterans/Heteropterans? The first use of bug being applied to arthropods was in the 1620s in reference to bedbugs (in Hemiptera but not Heteroptera) with the term ladybug (not in Hemiptera) first attested in the 1690s. Both predate Linnean taxonomy. So why and when did entomologists decide to coin this highly restrictive definition? It’s a very English-language term so it surely wasn’t when the taxon was created by Linnaeus.
