High blood sugar doesn’t just increase your risk of developing diabetes—studies have also shown a link between blood sugar and dementia. Researchers tracked the blood glucose levels of more than 2,000 older adults for seven years and found that those who had high glucose levels—but not diabetes—were nearly 20 percent more likely to develop dementia than those with low levels.

Coral reefs continue to die until carbon output drops

Scientists have concluded for the last decade that more-acidic seas have been harming coral, making it more difficult for coral reefs to grow or regenerate themselves. Conducting an experiment over the course of 22 days, scientists flooded Australia’s Great Barrier Reef with an antacid. They found that by lowering the water’s acidity, it caused the coral to grow. Research has […]
