Hundreds of pupils from across north Wales took part in the Big Bang competition where they put their engineering talents to the test.
Its extra-long roots make the soil more absorbent, which means more rain could be soaked up on higher ground.
Stephen Power was left with disfigured features after a motorbike crash. Surgeons used 3D equipment to plan complex surgery to help him.
A parody website called 'Google Naps' - based on Google Maps - features Cardiff. The website aims to help uncover "the world's coziest and coolest places to take a well-deserved nap", according to the creators.
Users can post their favourite suggestions for nap locations, giving details of the nap (whether on a bench, lawn, bed etc) and reasons why you should nap there. One of the Cardiff posts is listed as a bench in Catays Park. The post states: "the City Hall clock tower acts as an alarm clock".
The parents of murdered schoolgirl April Jones have criticised David Cameron for failing to clamp down on online images of child abuse.
Paul Jones accused the Prime Minister of reneging on a vow to take tough action on blocking internet images of abuse.
Jones told Channel 5 News: "I think he's hoodwinked us a little bit by coming out banging the drums, but hasn't actually put any money in place - he's left it to the internet (companies)."
He added: "When I last met David Cameron I said aim high - but he's fallen well short of the mark."
Last July, Cameron threatened to impose tough new laws on internet giants if they fail to blacklist key search terms for horrific images as part a crackdown on online porn unveiled today.
In November, Google and Microsoft promised to introduce new software that will automatically block 100,000 "unambiguous" search terms which lead to illegal content.
Coral and Paul Jones launched the campaign after Mark Bridger was found guilty of their daughter's abduction and murder last year.
The discovery of new drugs and development of new treatments will form the basis for a new science network launching today. One of three, the life sciences and health network, based at Cardiff University will work on areas that have unmet medical need.
Another area to be looked at will be the growing needs of society, such as the need for food. The network will carry out research into the relationships between land, water, the provision of food and energy production.
The network is one of three Ser Cymru National Research Networks for Wales launching today. They are funded by £7m from the Welsh Government and are designed attract more scientific research business to the country.
One of three new science networks launching today will focus on materials and engineering. It aims to carry out research that could have applications in manufacturing.
One area of research for the network, based at Swansea University, will be solar technology. Different materials that could be used to coat buildings to harness solar energy, instead of using solar panels, are already being discussed.
Wales is to gain three new science networks. The Ser Cymru National Research Networks for Wales are the product of a £7m investment by the Welsh Government. They are designed to attract scientific research business and cover various disciplines from medicine, manufacturing, energy and food security.
The Army's latest "spy in the sky" unmanned aircraft, which was tested in Wales, is due to begin flying over British skies this week.
Watchkeeper, a reconnaissance and surveillance unmanned air system (UAS), has a wingspan of 35 feet and can fly at an altitude of up to 16,000 feet.
It has been designed to loiter over areas of interest for "significantly longer" than existing systems, providing clear surveillance pictures to troops on the ground.
