John Glenn

John Glenn, o primeiro norte-americano a orbitar em torno da Terra, tornou-se símbolo de patriotismo e perseverança. O último sobrevivente dos pioneiros da era do espaço morreu esta quinta-feira. A história dele é uma lenda.

All ESEA training activities are specifically designed for teaching professionals in STEM disciplines (Science, Technology, Engineering, and Mathematics). The common objectives of ESEA training activities are to introduce teachers to implementing inquire based science education, as well as resource based and project-based teaching approaches.
2016 training activities here.

Be a Cassini Scientist for a day

 The 'Cassini Scientist for a Day' competition returns for a 2016/2017 edition. The competition is designed to give the participants a taste of life as a space scientist. Students are invited to submit a 500-word essay explaining their choice of one of three targets imaged by the Cassini spacecraft, in orbit around Saturn, over the past few years.
Be a Cassini Scientist for a day
To enter the competition, school students (10 –18 years old) from participating countries need to find out as much as possible about the beautiful planet Saturn, its fascinating features, and mysterious moons. Students must then choose one of the three targets imaged by Cassini and write an essay to justify their choice to a panel of experts.

The closing date for the competition in these countries is 23:59 CEST, 3 April 2017. More.

Silly putty makes seriously state-of-the-art sensors

Silly putty is more than just child’s play, according to a new paper – it's a key ingredient in a motion sensor precise enough to detect a spider’s tiny footprints.
Conor Boland, a nanophysicist at Trinity College Dublin in Ireland, and colleagues combined the popular children’s play-goo with graphene: single layers of pure carbon atoms bonded in a honeycomb formation. The result, dubbed “G-Putty”, was unveiled in Science.

Scientists are moulding photons into shapes to unlock the secrets of light

Individual particles of light called photons are considered to have no mass, but that hasn't stopped scientists from figuring out to precisely mould them into shapes up to 4 metres (13.1 feet) long.
In testing the ways light interacts with matter, the researchers found that the specific shape of a photon alters its effect on an atom. The discovery not only tells us more about the nature of light, but could also inform the development of the quantum technologies we'll use in the future. More.
