Bees play a vital role in the ecosystem, pollinating plants and ensuring food production. Bees provide us with valuable products that have been used for millennia in both cooking and body care such as honey, pollen, royal jelly, propolis, wax, and even poison.

However, bees are threatened from many sources, including habitat loss, pesticide use and climate change.

It is important that we all take steps to protect bees and their environment.

In this photo gallery, we offer eight practical tips to save bees.

History is unfortunately full of episodes in which natural catastrophes have claimed a very high number of victims.

Looking at the case history, among the main causes that have triggered natural disasters throughout history are earthquakes, followed by floods and cyclones. These are natural phenomena beyond the control of man, who often manages to do very little, even in terms of prevention, against them.

Each of us may go through moments of uncertainty at work, and recognising these signs could be crucial in preparing for change.

We have explored gestures, behaviours and situations that could indicate a threat to your job position, with the aim of providing awareness and inspiration to react positively in such circumstances.

In some of these cases, however, one is not appreciated and one is not to blame for this: if it happens, it is good to look around for a new opportunity.

It may sound like a trivial question, but in fact it is not trivial at all; on the contrary, it holds within it very important physical and philosophical questions. The Washington Post noted that this question is stirring up some of the people on Twitter these days.

The debate was generated by a tweet from journalist Jacqui Deevoy, who wondered how it was possible that the sun had 'changed colour' from what she remembered as a child. The answer, however, is one that leaves one somewhat appalled, as there is no real unequivocal answer.

After all, children do not make a mistake by drawing the sun as a big yellow ball, but it is not a completely right answer. After all, light is just the perception of the wavelength of radiation emitted by the sun, and therein lies the whole secret.
