Great science reads of the fortnight – Dec 1 2012

1. We’ve all heard of “white noise” but scientists have uncovered a smell they are calling “olfactory white”. The “white” or bland smell is based on a combination of odours and would probably not be found in nature. But it will help scientists to learn about the human olfactory system and brain.

2. A jumping spider called Nefertiti recently returned from a 100-day stay at the International Space Station. The experiment, devised by 18-year-old Egyptian Amr Mohamed, tested whether Nefertiti would be able to adjust her hunting methods in a low-gravity environment and then readjust back on Earth. The video shows how Nefertiti got the hang of hunting in low gravity.

3. Devastating floods have inundated California every 200 years for the last 2000-odd years, according to scientists who analysed sediment deposits. The last flood was in 1861…

5. Severe stress and chronic stress have opposite effects on the behavioural response of animals. This discussion of a study in mice shows scientists edging closer to understanding the physiology of severe stress.

    At the International Space Station ISS repairs are often needed on the exterior, the problem is it is a lot of work to send out a manned space walk to do this. Astronauts need oxygen and they have the problems of human error. Yet if we use robots, well they do not complain, unless programmed too. Robots in fact could spend months to fix something, astronauts five day space walk missions are about all we can muster right now and if we cannot get it done in time, imagine the cost for another launch. What about Fatigue factors, which take a toll on the organic components of the human body? Costs to send up a space crew to do repairs can be millions if not billions of dollars.*
