A new study in Nature Geoscience has uncovered more evidence linking regular changes in  Earth's orbital cycle to changes in the planet's climate

The new analysis of ocean sediment cores from 57 locations around the world suggests that the pattern of climate change over the past million years likely involves complicated interactions between different parts of the climate system, as well as three different orbital systems: eccentricity, tilt, and "precession," or a change in the orientation of the rotation axis.

Medical researchers at the University of Texas say they can detect obesity in infants just six month old, and a lot of children in the age group are obese and on track to maintain that status later in life.

By analyzing the electronic medical records of babies seen for routine "well-child" visits to the University of Texas Medical Branch at Galveston pediatric clinic, researchers  found that about 16 percent of 6-month-olds fit the criterion for obesity — a weight-for-length ratio that put them in the top 5 percent of all babies in their age group. 

Further analysis of the records indicated that obese 2-year-olds were much more likely to have been obese at 6 months than 2-year-olds who were not obese.
