Science highlights: human adult neurogenesis, and a fungus killing amphibians

A new study provides further evidence that the adult brain in humans does grow new neurons (a process called neurogenesis) in the hippocampus–the section of the brain where learning, memory, and mood regulation is controlled. These new brain cells may play a role in depression, PTSD, Alzheimer’s, epilepsy, etc. Read the article (Karen Weintraub, Scientific American, 25 March 2019). And, go to the source —…

Science highlights: dwindling seafood, Alzheimer’s/Parkinson’s and inflammation, today’s fast food, and disease-carrying mosquitos

Rising sea water temperatures have lowered the yield of 235 fish stocks globally by 4% since 1930. However, by 2100, water temperatures will increase more than 3 times the current amount since 1930, plus tropical fish haven’t been factored in, and they’re most at risk. The global seafood supply is decreasing. Read the article (Erik Stokstad, Science, 28 February 2019). Both Alzheimer’s and Parkinson’s may…

Science highlights: food waste, weather forecasting, 2080 climate, and sinking land

1/3 of all fruit & vegetables produced annually are thrown away because they appear marked or spoiled. A new edible food coating–already in use–helps food last 2-3 times longer and can cut down on food waste. (Charlotte Jee, MIT Technology Review, 14 February 2019). Weather forecasting has improved; accurate forecasts can now be made for 10 days in the future. But, there appears to be…
