Did you know that.....?
"There are 1.4 billion cows worldwide, each producing 500 litres of methane a day and accounting for 14% of all emissions of the gas.
Carbon dioxide is by far the biggest contributor to climate change, but methane has 23 times the warming potential of CO2 so reducing its emission is also considered important."
Of course you did....
Did you know kangaroo farts are environmentally friendly?
Ha ha you did not!
"Scientists already know that kangaroo stomachs are more than just green. Instead of methane, they produce acetate, a chemical that improves digestion. Feed laced with kangaroo bacteria could give rise to livestock that is not only greener, but also faster-growing and more fertile.
Methane-busting feed supplements could be available commercially in as little as three years, but some scientists point to a more direct solution – instead of slapping a hunk of beef or lamb on the barbie, why not kangaroo meat? This would help cap the marsupial population, which has reached plague proportions in parts of Australia, and connoisseurs say the meat is good. " It is also low in fat, high in protein and kangaroos are the ultimate free-range animal," says Peter Ampt of the University of New South Wales."
Next time you go to the local butcher ask...... no.... no.... demand for a pound of best kanga roast. By the way if you want to know more about farts go here.
Did you know that the scientists at the University of Michigan, created non-stick frog cells? Why? Leave the frogs alone they are becoming extinct!
There is something called antimicrobial peptides (AMPs) which are the first line of defence against bacterial infection in all animals from insects to frogs to humans. Boffins found the best form of AMPs called pexiganan in the skin of Xenopus laevis frog.
AMPs attack viruses, fungi and even cancer cells, so drugs designed to mimic them could have widespread medical applications. But there is a problem..... There is a protein-degrading enzymes called proteases, which is secreted by the bacteria and naturally present in the body. This stuff breaks the AMPs down before they can do any thing to the horrid bacteria. So the boffins increased the doze of AMPs but then the sticky part of the AMPs started attacking the host's cell membranes creating toxic effects eg kill the red blood cells.
In the meantime the Teflon is non stick. How? Teflon is fluorinated polymers, plastic-like compounds composed of chains of carbon atoms completely surrounded by fluorine atoms. Fluorine makes the surface slippery and inert to all chemicals.
So Neil Marsh biological chemist at the University of Michigan, "replaced certain amino acids in pexiganan with fluorinated alternatives, and called the new, non-stick peptide fluorogainin-1".
Did you know snot makes you smell better..... hang on you don't smell better with snot....... let us start again.....
Did you know snot enhances your sense of smell?
Mmmmm tricky this. I got a big nose because I used to dig me nose and eat the snot . Tasty!
First it is the itchyness in the nose which makes me dig it. Then as we all kids do taste it, does not matter what it is. As a baby we all did it, taste it. The salty taste is nice and daring so I kept on doing it when no one is watching me.
Right back to smell business. Here it is.
"Mucus, it turns out, separates the myriad chemical compounds that make up the smell of, say, frying onions. These compounds travel through the mucus at different speeds, hitting our scent receptors at different times. By dissecting and separating smells in this way, mucus allows our brains to identify scents more quickly and accurately.
It was with this in mind that, in April, Professor Julian Gardner of the University of Warwick started to improve his electronic noses, which have been used (without mucus) for years, in everything from the production of artificial fragrances to quality control in crisp factories.
"We built a polymer that replicates the function of snot," says Gardner. "It's not green but it has the same consistency as human snot and, applied to our sensors, means our artificial noses are at least five times better than those without snot.""
