We have introduced so much carbon dioxide into nature's operating system that we no longer know "what is an act of God and what is an act of man" when it comes to natural disasters striking with increasing frequency and overwhelming power, says Nathan Lewis, a chemistry and energy specialist at the California Institute of Technology.

It's been a few weeks since we moved house. After just two years in which we had managed to adapt, once again everything has changed: the environment that is closer to nature, the temperature, the housing, the placement of things in the house, the daily schedule, the children's school, the type of people we come into contact with, the type of activities, the...

"Hi, Alina! I hope you had a productive weekend" was the opening line of an email that, to me, encapsulated a whole misguided philosophy of life.

I love books as much as I love people, but if I’m honest with myself, sometimes I find a little more comfort in the company of books than in the presence of my fellow humans.

The journey "through the valley of the shadow of death" has never been easy. However, it has become increasingly lonely as our unfamiliarity with death has made us awkward and reserved when interacting with the dying.

Recently, I became a dad for the first time (that is, if you don’t count my miniature schnauzer, Banjo). Ever since my daughter was born, I’ve had a single thought going through my head: how do I ensure I don’t screw up my child?

Holiday greetings are a nice custom, but they are also an opportunity to assess how much we care about each other, how much we have grown closer or, on the contrary, how much we have grown apart over the past year.

My one-year-old son eyes the chickpea-filled bowl suspiciously. He tentatively pokes a stubby finger into the bowl and starts stirring the legumes around. I’m pretty sure it isn’t my imagination when, seconds later, his hazel eyes light up and his little pink lips curve ever-so-slightly upwards.

Bacteria are becoming increasingly resistant to antibiotics; some butterflies and fish are developing new colours for better camouflage; and a series of laboratory experiments have revealed small but significant changes in various microorganisms. Are these phenomena conclusive evidence of evolution unfolding before our eyes?

The biased sample is a kind of unrepresentative sample, either for quantitative reasons (as is the case with the too-small sample), or for qualitative ones, when its structure does not represent the structure of the real population that is the object of the research.
