Without water, humans cannot live. Since time began, we have lived by the water and vast tracts of waterless land have been abandoned as too difficult to inhabit. A new machine which extracts water from air could change that …

How much should we drink?
To answer the most important question, there is no correct or magic formula to follow to ensure you are properly hydrated each day. However, there are guidelines that you can follow to ensure that you get as close as possible to the perfect daily water intake. The most important aspects to take into consideration are your body weight, environmental conditions, diet and your level of fitness.

Excuse me, I have to sit down, my brain is hurting. (Clearly, not enough water). Okay. So, not a conundrum, it’s something else. Moving swiftly along!
What are antioxidants?

Over time, free radicals can damage cells and cause disease. Antioxidants are like microscopic police officers who seize these bad guys that plan to harm our cells. Read more
Cracking the problem of river growth
A general mathematical theory that predicts how cracks spread through materials like glass and ice can also predict the direction in which rivers will grow, according to a new MIT study.
Scientists at MIT have now applied this theory to the growth of river networks, finding that as a river fed by groundwater cuts through a landscape, it will flow in a direction that maintains symmetric pressure from groundwater around the river’s head. Read more
