Mice Fall Short As Test Subjects for Humans’ Deadly Ills – Data obtained from mouse models of sepsis, burns, and trauma have been misleading. Nearly 150 drugs developed to treat sepsis in humans have failed. A manuscript published in PNAS last month demonstrated why- mice have a condition that looks similar to human sepsis but is very different biologically. The decade long study analyzed genes used by white blood cells when responding to sepsis. The investigators found a panel of genes that were upregulated in response to sepsis in humans and then analyzed the response in mice to see if a similar panel of genes were involved. Surprisingly, there were no similarities between organisms. Additionally, in samples from human patients, a similar panel of genes were involved in the response to burns, sepsis, and trauma suggesting that finding a drug to treat one condition will treat all 3. While in many situations, mice are an ideal genetic model to human disease, this work suggests that mouse models cannot be used to develop drugs for all human conditions.  (Gina Kolata)

How To Find a Food Desert Near You – A food desert is an area where it is difficult to access large grocery stores that offer fresh and affordable food. To identify regions where access to healthy foods is limited, the USDA has recently released the Food Access Research Atlas.  Using the atlas, you can identify regions where there is low access to grocery stores. Additionally, income data has been incorporated into the map to compare low access to low income regions. (Nancy Shute)

Inequality Quantified: Mind the Gender Gap – While the number of women working in science and engineering fields has increased, universities still employ more men than women in STEM fields, and men still earn significantly more in these fields. Currently, only 21 percent of science professors and 5 percent of engineering professors are women. One potential cause of this problem is that a larger percentage of women quit scientific careers in the earlier stages to raise a family. Additionally, women only make 82 percent of what male scientists earn in the United States, and this gap is larger in European countries. Many universities are conscious of the need to correct the gender gap. (Helen Shen)
