In quantum physics, you can't precisely measure momentum and position simultaneously. They are an example of conjugate variables, connected by Heisenberg's Uncertainty Principle. There are workarounds, such as "weak measurement," to measure both at the same time but a new study says that a technique called compressive sensing also offers a way to measure both variables at the same time, without violating the Uncertainty Principle.

A recent paper found that exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia, and that led them to conclude that smog causes autism.

Male mice had more changes and the mice also performed poorly in tests of short-term memory, learning ability, and impulsivity.

A new data analysis technique
in the journal PLoS Computational Biology improves monitoring of kidney patients and could lead to changes in the way we understand our health.

The research uses the Science 2.0 approach to make sense out of the huge number of clues about a kidney transplant patient's prognosis contained in their blood. Using big data analysis of the samples, scientists were able to crunch hundreds of thousands of variables into a single parameter indicating how a kidney transplant was faring.

That allowed the team of physicists, chemists and clinicians to predict poor function of a kidney after only two days in cases that may not previously have been detected as failing until weeks after transplant.

Kids with glasses were once stereotypically considered smarter - expensive prescription specs did not lend themselves to sports so it made some sense they would focus on books due to the biological hand that was dealt them

But it may be that needing glasses is an indicator of knowledge if other ways - glasses may be created by learning. A recent paper found hat attaining a higher level of education and spending more years in school were associated with a greater prevalence and severity of myopia - nearsightedness.

The authors say they are the first population-based study to demonstrate that environmental factors may outweigh genetics in the development of myopia. 

You see advertisements for fitness apps on smartphones all of the time. Apple prides itself on convincing you that you will be a better dancer and healthier if you buy their phone. The problem is that the people most likely to use a fitness app for more than a week are least likely to need it.

Or maybe they do, according to recent Scare Journalism. In the health fad culture perpetuated by mainstream media, there is now a War On Sitting. Once some crazy claim appears in the New York Times, studies are going to crop up affirming exactly what popular media claims say. 

A new paper based on an analysis of sleep and cognitive (brain function) data from 3,968 men and 4,821 women who took part in the English Longitudinal Study of Ageing (ELSA) indicates that sleep problems are associated with worse memory and executive function in older people. 

Respondents reported on the quality and quantity of sleep over the period of a month and the results showed that there is an association between both quality and duration of sleep and brain function which changes with age.
