The camera and lens that Wally Schirra and Gordo Cooper carried into space during their Mercury Program flights is going up for auction in a few weeks. 

Wally Schirra, a known camera enthusiast, said the Hasselblad camera they used was held in highest regard by photographers for its superior engineering, craftsmanship, and top-of-the-line quality. He reportedly purchased the Hasselblad 500c camera at a Houston photo supply shop in 1962, and brought it back to NASA for mission use preparation.

An organic compound called limonene provides the pleasant smell of cleaning products and air fresheners but some byproducts of these sweet-smelling compounds could be adding to the air while they remove germs and odors.

By cleaning your house, you could be adding smog and ozone to it. 

Aircraft propelled by beams of light rather than fuel? Laser-propulsion just got a step closer thanks to a new method for improving the thrust systems developed by physicists Yuri Rezunkov of the Institute of Optoelectronic Instrument Engineering and Alexander Schmidt of the Ioffe Physical Technical Institute in Saint Petersburg. 

Currently, the maximum speed of a spacecraft is limited by the amount of solid or liquid fuel that it can carry. Achieving higher speeds means that more fuel must be burned—fuel that, inconveniently, has to be carried by the craft and hefted into space. These burdensome loads can be reduced, however, if a laser—one located at a remote location, and not actually on the spacecraft—were used to provide additional propulsive force.

How can the international community know it is election time in the United States? A whole raft of claims about science and why you should vote one way or the other will be produced. Some people have even claimed politics is hard-wired, which would mean that American Republicans and Democrats are distinct species, having branched off from the rest of the world in 1860.

While biologists laugh at the idea that voting preferences are biological, sociologists, psychologists and political scientists continue to match surveys to science and claim it might be true. What if only tall people voted Democrat and they only married other Democrats? Would that not shape evolution? Democrats would be tall and imposing and psychologists would say they will get their way more often.

The United Kingdom's National Health Service (NHS) is very popular with people who have no serious issues, because it is free - if they have to wait a few weeks, it is no big deal. For doctors, it isn't so great. The cost to attend medical school is not high, around $15,000 per year, but in their first year they will only earn about $30,000 annually. A specialist is almost 50% higher and that is part of the reason why the UK is losing General Practioners, at the bottom of the wage scale, faster than they can replace them.

Ebola is causing a lot of concern, a few instances in the United States were enough to lead to calls to overthrow the FDA vaccine approval process and the White House declared that the United States Department of Health and Human Services was unqualified to manage a handful of cases in America so they put a lawyer in charge as an Ebola czar. The National Institutes of Health said they could not fix the problem with the $330 billion they have gotten since 2001 but they are just exploiting an outbreak for personal gain also. In reality, the impact of disease outbreaks has been declining on a per capita basis for decades.
