I figured a Bank Holiday Weekend (UK) deserved a double-whammy of News Posts here on DC this, here is part 2 of the Weekend Roundup!

Methane vents bubble up off US coastmethane bubbles

Researchers say they have discovered more than 500 bubbling methane vents on the seafloor off the US east coast. Fire ice: The energy of the future? Japan taps gas from methane hydrate Antarctic may host methane stores



Warning sign on the road to the Bardarbunga volcano (20 August)Iceland lowers aviation risk warning

Iceland lowers the warning level to aviation from the Bardarbunga volcano, but say an eruption "cannot be excluded". '50-50 chance' of eruption Watch 'Melting ice could trigger eruptions' Watch How 2010 volcano chaos unfolded



Galileo satellites go into wrong, lower orbit

The European Space Agency (Esa) says the latest two satellites for Europe's version of the American GPS satellite navigation system have not gone into the correct orbit.



Study creates 'time travel' illusion

Virtual reality can be used to give the illusion of going "back in time", according to an exploratory study. In this virtual world, subjects were able to reduce how many people a gunman killed, an event they had unknowingly been part of.



You'll be able to charge your car wirelessly from 2017

Electric cars certainly have potential, but it's a pain having to plug them in to charge - give it three years though and you'll be able to ditch those annoying cables.
Wireless car charging technology is already up and running on the safety cars of the new Formula E championship - the world's first fully electric racing series - and from 2015 even the race cars will charge wirelessly.



Tor Project's struggle to keep the dark net in the shadows

The BBC has interviewed Andrew Lewman, executive director of the Tor Project.

His US-based team creates software that lets people visit websites anonymously and access otherwise hidden parts of the internet.

An article based on the interview can be found here, which focuses on Mr Lewman's belief that cyberspies in the US and UK are leaking his team information, frustrating their colleagues' efforts to compromise Tor's special browser software.



Hot-Spring Bacteria Reveal Ability to Use Far-Red Light for Photosynthesis

Bacteria growing in near darkness use a previously unknown process for harvesting energy and producing oxygen from sunlight, scientists have discovered.

Seeing past the jellyfish sting

Robots that hunt down and exterminate jellyfish: Good or bad idea? Discuss.

A 2013 video from robotics designers at the Korea Advanced Institute of Science and Technology shows three jelly-killer prototypes gliding as a metallic fleet over gently rippling water. An underwater video demonstrates the cunning plan. Pale jellyfish bells drift into view, and a blenderlike slicer whirs into action. Jellies explode in beige puffs as they are sucked into the spinning blades.

Hydrogen-Generating Water Splitter Runs on AAA Battery

Rather than emit greenhouse gases into the atmosphere the way gasoline does, fuel cells running on hydrogen release water. Until now, the clean way to produce hydrogen required the use of prohibitively expensive precious metals. Now, researchers have developed a water-splitting device that runs on ordinary, store-bought batteries. The work was published in Nature Materials this week.

Sinkhole so deep you can't see the bottom opens up in County Durham

The huge hole in the ground is already 100ft wide, with fears it will continue to grow after more rain.




WATCH: North Korea as you've never seen it before

In an incredible series of videos, British photographer Rob Whitworth has travelled to a number of countries in the far-east.

In a not often explored path, the filmmaker chronicles the daily life in North Korea's capital Pyongyang.

The rare view of the city, sees him given access to areas which are rarely covered by Western media outlets.

Mr Whitworth did admit that they were constantly accompanied while filming and there were restrictions on what they could or could not shoot.
