Weather associated with sentiments expressed on social media

Researchers found temperature, precipitation, humidity, and cloud cover associated with positive or negative expressed sentiments. Positive expressions increased up to 20 degrees Celsius before declining over 30 degrees Celsius, while high humidity and cloud cover were linked to negative expressions.

Drinking baking soda could be an inexpensive, safe way to combat autoimmune disease

Medical College of Georgia scientists found that drinking baking soda encourages the spleen to promote an anti-inflammatory environment, reducing destructive inflammation in autoimmune diseases. This shift was observed in rats and healthy people, with a reduction in pro-inflammatory cells and an increase in anti-inflammatory macrophages.

Sunlight works against oil clean-up efforts

Researchers found that sunlight has a significant impact on oil clean-up efforts, decreasing dispersant effectiveness by four-fold. The study's findings suggest that photochemical oxidation, triggered by sunlight, is a dominant weathering process that should be considered in future field manuals and oil spill response guides.

Study suggests older surgeons produce lower mortality rates in emergency procedures

Research from UCLA and Harvard T.H. Chan School of Public Health found that surgeries performed by older surgeons (age 50 and up) have lower patient mortality rates than those performed by younger surgeons. The study also showed that female surgeons in their 50s had the lowest patient mortality rate, regardless of age group or gender.
