Great Barrier Reef spared Unesco 'in danger' listing

The reef contains a higher degree of biodiversity than any other World Heritage site
United Nations heritage body Unesco has voted not to put Australia's Great Barrier Reef on its world danger list.
The decision has been welcomed by the state of Queensland, which generates billions of dollars in tourism revenue from the reef.
Despite deciding against giving the reef protected status, Unesco did warn that it faced "major threats".
The reef, which stretches 2,000km (1,200 miles) along the coast, is the world's largest living ecosystem.
Jackie Trad, Queensland's deputy state premier, told the BBC she was "absolutely pleased about the decision".
"It was an incredible moment in history, in Queensland and Australian history," said Ms Trad.
She acknowledged there had been a decline in the health of the reef, but said that the Queensland government had made "strong commitments" to protecting it.
Australia will have to report back to Unesco at the end of 2016 and again in 2020 to show its implementation of the body's recommendations.

Dredging danger

Some environmentalists had argued that the reef needed to be added to the 45 sites already on Unesco's list in order to protect it from worsening water pollution and major coastal development projects.
At the talks in Bonn, Germany, Greenpeace voiced concerns that the approval of the development of new coal ports would mean new dredging - removal of parts of the seabed - on the Queensland coast.
"Until the plans for the massive coal mine and port expansion are dropped, it's impossible to take Australia's claims that they are protecting the reef seriously," Greenpeace's Jess Panegyres said.

The reef generates a vast amount of tourism revenue for Australia
Dermot O'Gorman, of the WWF conservation group, said that the committee's decision "places Australia on probation".
Australia said it had "clearly heard" the concerns of the environmental groups and would commit an additional A$8 million ($6.2m; £3.9m) for monitoring the reef.

'Enormous scientific importance'

A report published in 2014 concluded that the condition of the reef "is expected to further deteriorate in the future". Climate change, extreme weather, and pollution from industry were listed a key concerns.
Earlier this year, Australia submitted a plan to Unesco outlining how it would address the threats to the reef.
This included a proposed objective of reducing pollution by 80% before 2025, as well as reversing a decision to allow dredged material to be dumped near the reef.

  • The Great Barrier Reef includes 3,000 coral reefs and 600 islands
  • It is the world's largest marine park, covering 348,000 sq km
  • It contains 400 types of coral, 1,500 species of fish and 4,000 kinds of mollusc
  • It attracts about two million tourists each year.
  • The region contributes A$6bn ($4.6bn; £3bn) a year to the Australian economy

The reef - a vast collection of thousands of smaller coral reefs stretching from the northern tip of Queensland to the state's southern city of Bundaberg - was given World Heritage status in 1981.
The UN says this is the "most biodiverse" of its World Heritage sites, and that is of "enormous scientific and intrinsic importance".

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 ...
