Weekly Science Picks
FollowWe have come to the end of one more week and it’s time to summarise what has happened during this week. As usual, the task was quite challenging, but we made it. Here is the review of the most exiting and fascinating news from the world of science and technology.
Do coffee and tea really dehydrate us?
They enjoy the taste and the fact that the caffeine wakes them up. But when we’re exhorted to drink six or eight glasses of water a day, it’s usually emphasised that drinks like coffee and tea don’t count towards your daily liquid total because they’re dehydrating.

The findings are surprising considering Mercury wasn’t supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed.
That’s all for this Sunday! Until next meeting, stay thirsty for new scientific stories.
