The Bubonic Plague wiped put a giant swath of the affected populations, it was truly an Old Testament wrath-of-God phenomenon - but it also led to a wave of agricultural innovation and the creation of a middle class (How The Bubonic Plague Made Europe Great).

It also did what folklore says about things that don't kill you - it made us a little stronger.

PROVIDENCE, R.I. [Brown University] — Different manifestations of preeclampsia, such as early vs. late timing or typical vs. high severity, appear to have distinct genetic underpinnings, suggesting that they may need to be studied and treated differently. That and several other insights are described in a newly published comprehensive review of genetic studies of the condition, which produces life-threatening complications such as high-blood pressure in as many as 8 percent of pregnancies in the United States.

Leesburg, VA, May 5, 2014—Misinformation and misunderstanding about the risks associated with ionizing radiation create heightened public concern and fear, and may result in avoidance of screening mammography that can detect early cancers.

Leesburg, VA, May 5, 2014—Breast tomosynthesis in the diagnostic workup for one- or two-view focal asymmetry detected at screening mammography resulted in less use of ultrasound, fewer biopsies, and higher positive predictive value for cancer than when diagnostic exams involved only 2D mammography, according to a study conducted at the University of Virginia.

"Tomosynthesis has been evaluated in screening populations and been shown to decrease recall rates," said researcher Brandi Nicholson, "but studies in the diagnostic setting are lacking."

 A computer simulation called "Illustris" has created the first realistic virtual universe - it can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution.

A bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature has been created. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

The team of researchers behind this have been working since the late 1990s to find pairs of molecules that could serve as new, functional DNA bases—and, in principle, could code for proteins and organisms that have never existed before.
