... in the research journal Astrophysical Journal Letters. On the other hand, researchers with Kristianstad University in Sweden and other institutions reported on Sept. 8 that some tiny Earth animals called tardigrades proved surprisingly resilient in outer space. Dried-out tardigrades lived for 10 days unprotected in that environment, and went on to reproduce, these scientists wrote in the ...

I am interested in the common brown ticks found on pets. The ticks are unusally good at surviving on these animals, even if they are shaken/thrown off, tramped upon, without nutrition (blood) etc. I would like to know how their genes could have evolved to such a high level of survival. Steve.

... constant. It can only increase the rate of reaction while the system is far from equilibrium. None of the enzymes in a living thing change the equilibrium constants. They can't make a reaction that is thermodynamically impossible occur. This is why plants need sunlight and animals eat plants. The enzyme can only make a reaction occur faster, it can't make the impossible happen.

... ribosome in bacteria and archaea. These "molecular signatures" were so pronounced that Woese concluded that the archaea comprised a separate domain of life, distinct from bacteria and eukarya (animals, plants, fungi and protists). His classification system is now widely accepted. "Carl Woese and his colleagues years ago established that protein translation had to be well developed when the...

Rather than sleep daily like flies and other animals, the growing worm takes a 2-hour nap (a state called lethargus) every 7 to 12 hours at each of four developmental transitions. During these periods, the worm builds a new cuticle, restructures body ...
