Unesco to rule on Tasmania forest and Great Barrier Reef

An Australian plan to chop down 74,000 hectares of protected Tasmanian forest for timber will be discussed at a UN cultural organisation meeting which begins on Sunday in Qatar.
The Tasmanian forest is part of a Unesco World Heritage Site, but the Australian government wants this status revoked so logging can begin.
Thousands of people in Tasmania protested against the move on Saturday.
The government says the area is degraded as it has been logged before.
If the bid succeeds, Australia would become the first developed nation to have reversed the protected status of a forest on economic grounds.
Australian Prime Minister Tony Abbott has championed the cause of the timber industry, which employs more than 66,000 people.
The opposition Greens party has labelled him a "dig it up, cut it down prime minister".
Wilderness Society spokesman Vica Bayley said: "Logging World Heritage forests is as reckless as destroying any other World Heritage site, like using the Grand Canyon as a garbage dump, knocking down the Sydney Opera House for harbourside apartments or selling the Eiffel Tower for scrap."
Another protected Australian site, the Great Barrier Reef, is also on the agenda of Unesco's World Heritage Committee meeting in Doha.
Canberra hopes to deter Unesco from downgrading the reef to "endangered status" because of pollution-linked deterioration.
Australian officials say that industrial chemical pollution levels at the reef have fallen significantly because of better agricultural and industrial practices.
However, critics say approval for a project to dump dredged sediment in the Great Barrier Reef Marine Park as part of a project to create one of the world's biggest coal ports presents a serious threat to the reef. Scientists have warned that the sediment could smother or poison coral.
Unesco is also expected to reclassify other world sites as protected areas, including the Inca Trail in Peru, the Rani-ki-Vav stepwell in India and the Chauvet Cave paintings in France.
The Great Barrier Reef is the world's largest coral reef
There are concerns that dumped dredged sediment will harm the Great Barrier Reef
The site is home to more than 1,500 species of fish, 4,000 species of molluscs, and 400 species of sponge

Che cosa sono i Campi Flegrei?

  Le recenti scosse di terremoto hanno riportato l'attenzione degli scienziati sui Campi Flegrei. Che cosa c'è in quest'area? Perché si chiama così? Che rischi ci sono?     Campi Flegrei: rendering in 3D dell'area a partire da immagini satellitari fornite dalla NASA. I  Campi Flegrei  sono un'area vulcanica attiva che si trova in Campania, nel golfo di Pozzuoli e che include (completamente o in parte) i comuni di Bacoli, Giugliano, Monte di Procida, Napoli, Pozzuoli e Quarto. Il nome Campi Flegrei deriva dal greco, sta per "campi ardenti, in fiamme" e dà l'idea di come  questa zona sia stata caratterizzata fin dall'antichità da attività vulcanica . A differenza del  Vesuvio , spiegano all'Istituto Nazionale di Geofisica e Vulcanologia, i  Campi Flegrei  non sono un unico  vulcano , ma un campo vulcanico, attivo da oltre 80mila anni, formato da diversi centri vulcanici distribuiti su un'area depressa chiamata  caldera : quest'ultima ...

Londonderry explosion: 'Firebomb' explodes in Everglades Hotel

No-one was injured in the explosion but the reception area was extensively damaged A masked man has thrown what police have described as a "firebomb" into the reception area of a Londonderry hotel. The Everglades Hotel, in the Prehen area of the city, was evacuated after the device was reported at 23:15 BST on Thursday. The device exploded a short time later when Army bomb experts were working to make it safe. No-one was injured in the explosion but the reception was extensively damaged. Deputy First Minister Martin McGuinness has tweeted: "Derry is a place looking to the future and will not be held back by those living in the past. Their attack on the Everglades must be condemned." PSNI Chief Superintendent Stephen Cargin said: "A masked man went into the hotel and left a hold-all at the reception desk saying he was from the IRA. 'Ball of flames' The device exploded in the reception area of the hotel when Army bomb experts were wor...

Valkyrie, il robot della Nasa

Costruito sul modello dell'uomo, si muove con grande libertà e può valutare situazioni critiche. Valkyrie, il robot della Nasa. La Nasa lo ha tenuto segreto per più di una anno, da quando cioè, durante il  Darpa Robotics Challenge  dell’anno scorso, disse che stava lavorando al progetto di un robot umanoide, insieme a prestigiose università Usa, ma senza svelarne le caratteristiche. Ora eccolo: è R5 (Valkyrie per gli amici), alto un metro e 90, 125 kg, autonomia assicurata dallo zaino battery-pack. Più umani dell'uomo AL POSTO DI CHI?  Valkyrie parteciperà alla prossima edizione della sfida tra robot - il Darpa - con prove impegnative, come il camminare su terreni irregolari, salire una scala, utilizzare attrezzi e guidare un’auto: ecco perché è stato progettato con dimensioni e fattezze umane. L’obiettivo ultimo di questi oggetti ad altissima tecnologia è insomma quello di sostituire l’uomo là dove è necessario, in zone o condizioni di estremo pericolo ...
