Yale study shows deforestation causes cooling

A Yale-led team found that deforestation in northern latitudes has a net cooling effect due to increased albedo from snow cover and reduced absorption of solar radiation. Temperatures decrease by an average of 1.5 degrees Fahrenheit north of Minnesota.

Deforestation causes cooling in Northern US, Canada

Researchers discovered a surprising link between deforestation and temperature changes, finding that areas north of 45 degrees latitude experience cooling effects due to increased albedo. However, this effect is not observed at lower latitudes, where deforestation may actually contribute to warming.

Form and function: New MRI technique to diagnose or rule out Alzheimer's disease

Researchers developed a new MRI technique called Arterial spin labeling (ASL) to measure changes in brain function, potentially replacing the current standard PET scan. The study found that ASL-MRI is comparable to FDG-PET in detecting Alzheimer's disease and has the advantage of being non-invasive and widely available.

Childhood obesity -- what are the health risks?

A new review of research into childhood obesity and metabolic disease in adulthood suggests that treating obesity during childhood can remove the risk of lasting harm. However, the study also found that being overweight or obese as a child may actually increase the risk of health problems later in life.
