According to NASA scientists, space smells a lot like my uncle's workshop. One can detect hints of fried steak, hot metal, and the welding of a motorbike. They have hired Steven Pearce, a chemist and managing director of fragrance manufacturing company Omega Ingredients, to recreate the smell in a laboratory. NASA will use his research to help train potential astronauts. Steven said, "I did some work for an art exhibition in July, which was based entirely on smell, and one of the things I created was the smell of the inside of the Mir space station. NASA heard about it and contacted me to see if I could help them recreate the smell of space to help their astronauts."

vile8 writes "With the high gas prices and ongoing gas gouging in my hometown many people are trying to find a reasonable way to save gas. One of the things I've noticed is people driving exceptionally slow, 30mph in 45mph zones, etc. So I had to take a quick look and find out if driving slow is helpful in getting better mileage. I know horsepower increases substantially with wind resistance, but with charts like this one from truckandbarter.com it appears mileage is actually about the same between 27mph and 58mph or so. So I'm curious what all the drivers out there with the cool efficiency computers are getting ... of specific interest would be the hemis with MDS; how do those do with the cylinder shutoff mode at different speeds?" Related: are there any practical hypermiling techniques that you've found for people not ready to purchase a new car, nor give up driving generally?

We discussed the Galaxy Zoo project soon after it launched last summer. Science News is now following developments about an odd celestial object that is fueling a lot of excitement among astronomers around the world. In August, a Dutch schoolteacher named Hanny, in the process of characterizing galaxy images, noticed a peculiar object and posted a query about it on the Galaxy Zoo blog. She called it a "Voorwerp," which Science News says is Dutch for "thing" but which Google translates as "subject." Hanny's Voorwerp emits mostly green light (the earlier report said blue). The best guess astronomers have now is that the Voorwerp is emitting "ghost light," i.e. it is "lit by the ultraviolet light and X-rays from a quasar that has vanished in the last 100,000 years," to quote astronomer Bill Keel. "As far as we can tell, it's an unprecedented thing," Keel added. Researchers are scrambling to book time on the Hubble and other major telescopes to get a closer look.

ISRO, Indian Space Research Organisation, is planning to send a robot for its mission to moon. It is probably going to be made by students and profs of IIT-Kanpur (the Indian equivalent of MIT). The two-legged robot, fitted with sophisticated sensors and high-resolution cameras, is capable of recording information and images using laser beams. It can also detect the distance of a hindrance, enter a small crater, bring surface samples and return high resolution images to the lunar vehicle. It balances cost and sophistication; basic functionality for only $50,000.

Parallax Blue writes "The Independent is reporting new findings that indicate a common additive called sodium benzoate, found in soft drinks such as Fanta and Pepsi Max among others, has the ability to switch off vital parts of DNA in a cell's mitochondria. From the article: 'The mitochondria consumes the oxygen to give you energy and if you damage it — as happens in a number of diseased states — then the cell starts to malfunction very seriously. And there is a whole array of diseases that are now being tied to damage to this DNA — Parkinson's and quite a lot of neuro-degenerative diseases, but above all the whole process of aging.' European Union MPs are now calling for an urgent investigation in the wake of these alarming new findings."
