CDC assesses potential human exposure to prion diseases

The CDC study found that a significant proportion of respondents had traveled to countries with reported prion diseases, increasing the risk of exposure. Hunting and venison consumption were also associated with increased risk of prion disease exposure, particularly in areas with chronic wasting disease.

Weight gain between first and second pregnancies increases woman's gestational diabetes risk

Women who gained 2-3 BMI units between the first and second pregnancy were more likely to develop GDM in the second pregnancy. Conversely, women who lost over 6 pounds between pregnancies reduced their risk of developing GDM by approximately 50%. The association was strongest in women who were overweight or obese in their first pregnancy.

Common Jupiters?

A recent study using data collected between 2006 and 2007 found evidence for 10 free-floating planets roughly the mass of Jupiter, suggesting they are common. The discovery supports the 'ejection' scenario where planets are kicked out from their solar systems due to close gravitational encounters with other planets or stars.
