Weekly Science Picks

It’s Sunday! It’s a perfect day for your holiday, relaxation and joy. The good thing about every Sunday is nothing will force you to get up that early in the morning as you do during the working week. Well, that’s why this day is our opportunity to summarise what have happened over the last 7 days. So, let us review with you the best moments of this week!

Sprouting feathers and lost teeth: scientists map the evolution of birds

A remarkable international effort to map out the avian tree of life has revealed how birds evolved after the mass extinction that wiped out the dinosaurs into more than 10,000 species alive today. More than 200 scientists in 20 countries joined forces to create the evolutionary tree, which reveals how birds gained their colourful feathers, lost their teeth, and learned to sing songs.

A different kind of show and tell

Imagine you’re back at school, and one day the teacher has something for show and tell. Someone, actually. A real live scientist, or mathematician, or ICT specialist. And not just the once.

Water vapor on Rosetta’s target comet significantly different from that found on Earth

ESA’s Rosetta spacecraft has found the water vapor from its target comet to be significantly different to that found on Earth. The discovery fuels the debate on the origin of our planet’s oceans. One of the leading hypotheses on Earth’s formation is that it was so hot when it formed 4.6 billion years ago that any original water content should have boiled off. But, today, two thirds of the surface is covered in water, so where did it come from? In this scenario, it should have been delivered after our planet had cooled down, most likely from collisions with comets and asteroids.

Could a diet supplement supercharge your eyesight?

Eyesight is an easy thing to take for granted, but our ability to see is one of the human body’s most incredible senses. And there’s a lot more to it than simply discerning objects in the distance. Our eyes are capable of dealing with huge variations in contrast, for example.
