Quirky Science Facts!

It is now 400,000km off course and slowing down at a rate of less than 100 millionths of a centimeter per second.
Sorry but you have got something wrong there as "slowing down at a rate" is a rate of change of speed (acceleration) and "100 millionths of a centimeter per second" is a speed so the sentence doesn't make any sense. :eek2:

 

If you think you are quoteing a speed, you don't tell us how long it takes for it to slow down that much; a second, a minute, an hour, a day, a month ... . Essentially, as stated, what you are saying is that every second it slows down 100 millionths of a centimeter. That is like saying my car slows down three feet when I hit the brake. :)

 

Have fun -- Dick

Tardigrades are the toughest creatures on the planet!

From Wikipedia:

1. Tardigrades can survive being heated for a few minutes to 151 °C or being chilled for days at -272.8 °C (almost absolute zero).

2. Radiation— Shown by Raul M. May from the University of Paris, Tardigrades can withstand 5700 grays of x-ray radiation. (Five grays would be fatal to a human).

3. Pressure—They can withstand the extremely low pressure of a vacuum and also very high pressures, many times greater than atmospheric pressure. In theory, they could even survive the vacuum of space, though the possibility of it is slim.

 

Hardy little things:)

Electrophoresis - Analysis of substances by pulling constituents through a viscous gel using the force of an electrical field. Various fractions travel at different rates, resulting over standardized time intervals in characteristically spaced bands seen in the gel!

Electrophoresis...

...In 1943, UC officially takes over operation of the government laboratory at Los Alamos, N.M., that is continuing the work of Berkeley faculty and others in the development of the atomic bomb...I withdraw
oh well it was a cool idea anyways. I'd have loved to be able to tell My ex that her brother was getting irradiated while he was there...:eek2:

 

 

 

there are 2 main types of circulatory system, Open and closed

 

Open has no diferentiation between blood and interstitial fluid.

 

Closed has a distinct seperation between the blood and the rest of the body's fluids, relying on a series of arteries and veigns for transport.

 

Open is also usually copper-based and about 1/3 as efficient as closed which is usually iron-based.

...the two systems, of course, being easily discernable by the colour of the blood!

 

Iron based - (most animals) blood is red when oxidized.

Copper based - (molluscs, etc) blood is dark blue when oxidized!

 

Research is currently underway to use pig's blood (only the colourless plasma part of it) together with plant-based clorophyl for carrying oxygen for emergency blood transfusions. So pretty soon, is someone at work cuts his finger and bleeds green, you'll know he was in hospital recently! Will do wonders for anemics, although they will look a bit off-colour...

cool - and should take a load off us blood doners! :eek2:

Through embriology, it became clear that our lungs developed from aquatic air-bladders! Human foetuses first develop the circulatory equipment for gills (actually having the proper gill-slits as well) before the air bladder develop to assume the breathing role.

 

In other words, aquatic animals first had to learn how to swim upright and control their buoyancy before land animals could breath!
