Australia storms: Cyclones hit Queensland and Northern Territory

Two major storms have slammed into Australia, knocking out power, damaging homes and forcing evacuations in coastal areas.
Tropical Cyclone Marcia hit the Queensland coast between Yeppoon and St Lawrence on Friday morning local time.
Arriving with little warning as a Category Five storm, it has now been downgraded to a Two but still threatens high tides and heavy rain.
Separately, Tropical Cyclone Lam hit a remote area of the Northern Territory.
'Terrifying experience'
In its latest update, the BOM said Marcia had weakened to a Category Two cyclone, with sustained winds of 110km/h (72mph) and gusts of up to 155km/h.
It was about about 60km west of the town of Gladstone, Queensland and 65km north-northeast of Biloela, and moving south-southeast at 18 kmh but expected to weaken below cyclone strength by Saturday morning.
"Destructive winds" battered coastal and island communities including Yeppoon in Queensland
About 870 Yeppoon homes were evacuated because of possible storm surges
Surfers off the Gold Coast made the most of the rough sea conditions
The BoM warned of abnormally high tides and said people in coastal areas should be ready evacuate if necessary.
Earlier on Friday, the storm passed through Rockhampton and Yeppoon, where Queensland Premier Annastacia Palaszczuk said people of had gone through a "terrifying experience".
"We are very, very thankful that we have avoided the worst of what could've been an absolute catastrophe if those winds had escalated and the Category Five had gone straight over Yeppoon," she told reporters in Brisbane.
Ms Palaszczuk said earlier that 33,000 residences were without power in the Livingstone/Yeppoon area and 20,000 in Rockhampton.
There were no reports of injuries, but some homes and businesses suffered significant structural damage, she tweeted.
In Yeppoon, about 870 homes were evacuated because of storm surges, according to Queensland emergency authorities.
More than 170 schools and childcare centres had been closed, and people evacuated or moved to safety on both Lady Elliot Island and Heron Island, on the Great Barrier Reef.
The mayor of Rockhampton, Margaret Strelow, told ABC Radio that Marcia was like "a real moving beast" as it appeared to head first to the west of the city and then to the east.
Further south, local media reported that 90,000 sandbags had so far been handed out across Queensland's major city, Brisbane, because of predictions of heavy rain and flooding.
Describing the cyclone as "very serious", Prime Minister Tony Abbott said: "Let's hope we can get through it without any loss of life."
Roads impassable
Cyclone Lam, which arrived as a Category Four, struck close to the tiny and remote indigenous settlements of Elcho and Goulburn Island, east of Darwin.
Some communities had been evacuated ahead of the storm, but others spent the day in emergency shelters.
These children were evacuated to Darwin along with their entire community from Goulburn Island
Regional police commander Bruce Porter said Elcho Island had no power or water, and that there had been "substantial" damage.
"Initial reports are the airstrip is still intact but covered with debris," the AFP news agency quoted him as saying.
"There are downed power lines. There are a number of trees down and many roads are impassable and we do have a number of buildings and houses that have been severely damaged."
Lam has now been downgraded to a tropical low, but Australia's Bureau of Meteorology (BoM) warned of further "squally thunderstorms" and high tides.

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 ...
