First ever production of 'anything' on another planet by humans makes this real landmark achievement. Well done MIT & NASA. I was going to say they going to need to scale it 1000 fold fairly quickly, then I thought perhaps I should consult Dr Google, then changed my mind and instead I should try to work out, albeit in a rough and ready style.Nasa’s Moxie instrument successfully makes oxygen on Mars
Researchers hope scaled-up version could one day generate oxygen to sustain humans on Marswww.theguardian.com
A death from an attack by a 'pet' kangaroo - First fatal kangaroo attack since 1936 as man killed on property in WA's Great Southern The last kangaroo related death was apparently 1936. The article has some interesting discussion about why roos may attack. Many years ago, while camping I was challenged by a big roo. Each night animals had been around the tent and pulled our rubbish bags apart. Eventually we tied them onto a tree thinking it would be out of reach, but it wasn't. On our last night I woke about 5.00m and could hear tearing noises, so bravely I leapt up and ran outside to shoo the roo away. There was one big male, tearing at the bag, a a few smaller females behind. The male stood up on its back legs and balanced on its tail, then lashed out with of its legs, fortunately missing me. Not wanting to see my bowel lying in the red dust I 'bravely' retreated.
Animal behaviorists will immediately understand how stupid I was to confront the animal in this way, especially with his females around. Heres some video of fighting roos.
For young folks, his video from last century shows Rags the red kangaroo fighting in a TV studio. While it is funny, it's also really dangerous. I don't think the OHS folks were in the studio at the time.
See how warm it gets when there is cloud cover at night? How cold it can get, even in the desert, without cloud cover?World’s whitest paint now thinner than ever, ideal for vehicles
The world’s whitest paint – seen in this year’s edition of Guinness World Records and “The Late Show With Stephen Colbert” – keeps surfaces so cool that it could reduce the need for air conditioning. Now the Purdue University researchers who created the paint have developed a new formulation...www.purdue.edu
I did think about...well where does the reflected heat go ? would it heat up the planet ? then i read that, wohoo it's reflected back into deep space...cooling down our planet...then i thought again...well...if it's reflected sideways or slightly downwards it's gonna hit trees, buildings, mountains, hills, dirt, bitumen, or even some dude standing next to a white car...they surely ain't gonna be painted white !!! so to say yeah it's gonna cool down your 'local' environ...good...but to draw a long bow and say it'll cool the planet...i scoff.
