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.
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 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.
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.
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
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.
