A bovine TB control strategy under consideration risks spreading the disease rather than supressing it, according to researchers who predict that culling badgers which test positive for TB could increase the movement of remaining badgers, potentially infecting more cattle with the disease.

In the past, we have seen how much it would cost to replace a housewife and how much it cost to raise a child.

What about a child with special needs?  A recent literature review of U.S. and U.K. studies on patients with autism spectrum disorders and their families in 2013 came up with the economic impact. 

Autism used to be rather specific but the modern range of autism spectrum disorders is really broad, so Ariane V.S. Buescher, M.Sc., of the London School of Economics and Political Science, and colleagues separate those with intellectual disabilities and those with just behavioral issues.

Is a person's race "fixed"? It seems not. Since race is a cultural construct, perceptions of race may shift as a result of changes to the perceiver's social goals and motivations, so it always seems a little silly for sociologists to do surveys or give Implicit Association tests and play with statistics and declare that X equals Y, but that is the state of the social sciences in the USA.

So psychologists have found, for example, that political ideology may influence the extent to which they see biracial individuals as being Black or White. Look for a lot more of this political ideology stuff since it is election season.

Banks have long expected that you should spend a third of your income on housing. Now humanities academics say that would help low-income families get optimal brain power for their children also. 

But don't overspend to try and get into a better neighborhood, they write, and we saw the disaster that 1960s subsidies brought to neighborhoods.

Four of the most common mosquito pesticides used along the east and Gulf coasts show little risk to juvenile hard clams and oysters, according to a NOAA study in Archives of Environmental Contamination and Toxicology.

The paper also determined that lower oxygen levels in the water, known as hypoxia, and increased acidification increased how toxic some of the pesticides were. Such climate variables should be considered when using these pesticides in the coastal zone, the study concluded.

Like breathing? Thank water. And the continents.

One of the greatest mysteries of evolution involves oxygen levels in the atmosphere. At various points throughout 4.5 billion years of geological history, carbon levels have been 10X what they are today, yet life pushed on. Today, oxygen concentration is 21% of the atmosphere. One of the biggest puzzles in geochemistry is how it went from trace amounts to just the right one.
