POPSAnimal senses humans don't have You might think you're smart, but none of your senses rival the keenest abilities in the animal world. Animals see in the dark, sniff prey miles away, and detect electrical output from muscle twitches in hidden meals. Read on, so you don't become one of those meals.<<

POPSWhy we may overlook extra-terrestrial life Ammonia, for example, has many of the same properties as water. An ammonia or ammonia-water mixture, stays liquid at much colder temperatures than plain water.Hydrogen fluoride methanol, hydrogen sulfide, hydrogen chloride, and formamide have all been suggested as suitable solvents that could theoretically support alternative biochemistry. All of these “water replacements” have pros and cons when considered in our terrestrial environment. What needs to be considered is that with a radically different environment, comes radically different reactions. Water and carbon might be the very last things capable of supporting life in some extreme planetary conditions. In any case, it is not beyond the realm of feasibility that our first encounter with extra-terrestrial life will not be a solely carbon-based occasion.

POPSCreative ways to recycle ordinary objects Recycling doesn’t have to be limited to helping the environment: it can also be a challenge and opportunity to ingenious designers who work with materials most people would consider waste to create amazing things. Some of the above designs serve multiple purposes: illustrating the material possibilities of what most would consider trash while also maximizing the aesthetic potential of what would otherwise be considered waste objects. Clothes become rugs, airline trolleys become furniture, cardboard becomes bridges and sewage turns into building blocks!

POPSHow do we replace a friend? Some days ago, a friend of mine died. Tina was very sick, since many years, but so calm and quite that to stay near her was like to stay under a tree in a summer day. There is no way to replace a friend like her. I'm sad, but today I want to say that I'm grateful I met her.
