I realized the other day that I have not posted anything here for a long time: Just about a month. I am going to start a new type of post - the links dump. Just a bunch of links to things around the Interwebs that I find interesting/important/amusing. They won't all be science-related - I do enjoy reading about things besides science.
Energy Drinks: The coffee of a new generation?
Several studies have demonstrated that strong doses of caffeine can increase hypertension, cause heart palpitations, provoke irritability and anxiety as well as cause headaches and insomnia. Health Canada does not recommend consuming more than two cans per day.
What causes schizophrenia?
Researchers in Sweden have revealed a surprising change in brain biochemistry that occurs during the training of working memory, a buffer that stores information for the few second required to solve problems or even to understand what we are reading. The discovery may have implications for understanding disorders in which working memory is deficient — such as schizophrenia and attention deficit hyperactivity disorder (ADHD).
Scientists find world's largest snake
The scientists estimate the snake lived 58 to 60 million years ago and was around 13 metres long. The giant, found in northeastern Colombia, dwarfs modern pythons and anacondas which usually don't exceed 6-6.5 metres and are thought to be the largest living snakes.
Amid rising childhood obesity, preschoolers found to be inactive
They found that the preschoolers were inactive for much of their preschool day, with 89 percent of physical activity characterized as sedentary. Even when they played outside, a time when children are expected to move around, 56 percent of their activities were sedentary
A much earlier start for animals
Where did all the animals come from? The fossil record is virtually animal-free up until the Cambrian Explosion 540 million years ago, and then--boom--thousands of critters of all shapes and sizes show up. The mystery has plagued scientists for more than a century and a half, beginning with Charles Darwin. Now, with a brilliant bit of detective work, researchers have located our missing ancestors.
