In 'reading' a gaze, what we believe changes what we see

Researchers found that when people believe another person cannot see, the effects of adaptation are greatly reduced, suggesting a bi-directional relationship between gaze processing and mental-state attribution. This discovery could lead to a better understanding of what goes wrong in individuals with autism.

In the warming West, climate most significant factor in fanning wildfires' flames

A study by the USDA Forest Service and university scientists found that climate plays a critical role in shaping wildfire behavior, particularly in the Western United States. Climate influences fuel production and drying, which varies among different ecosystems, leading to varying fire sizes and severities.

Kidney damage from medical imaging procedures can cause long-term health problems

A recent study found that contrast-induced kidney damage from medical imaging procedures increases the risk of having a stroke or heart attack over the next year or two. Patients who developed this damage had twice as many long-term negative health effects compared to those whose kidneys were not damaged.
