Koide Hiroaki: an insider's exposé of the Fukushima nuclear disaster

Katsuya Hirano & Hirotaka Kasai / Asia-Pacific Journal

17th March 2016

Koide Hiroaki has spent his entire career as a nuclear engineer, and has become a central figure in Japan's movement for the abolition of nuclear power plants. He met with Katsuya Hirano and Hirotaka Kasai to discuss the catastrophic nuclear meltdowns at Fukushima Daaichi in March 2011, and the crimes and cover-ups committed both before and after the event. more...

EDF's Hinkley C offices occupied as UK nuclear hopes wither

Oliver Tickell

15th February 2016

An occupation of EDF's site office for Hinkley C turned into a celebration today as the EDF Board postponed its 'final investment decision' for the tenth time. With strong opposition among French unions and the project afflicted by severe technical and financial problems, it's not just Hinkley that's going down, but the UK's entire nuclear programme. more...

Pandora's box: how GM mosquitos could have caused Brazil's microcephaly disaster

Oliver Tickell

1st February 2016

In Brazil's microcephaly epidemic, one vital question remains unanswered: how did the Zika virus suddenly learn how to disrupt the development of human embryos? The answer may lie in a sequence of 'jumping DNA' used to engineer the virus's mosquito vector - and released into the wild four years ago in the precise area of Brazil where the microcephaly crisis is most acute. more...

Nuclear renaissance? Failing industry is running flat out to stand still

Dr Jim Green

30th January 2016

Despite the endless rhetoric about a 'nuclear renaissance', there are fewer power reactors today than there were a decade ago, writes Jim Green. The one country with a really big nuclear build program is China, but no one expects it to meet its targets. And with over 200 reactor shut-downs due by 2040, the industry will have to run very hard indeed just to stay put. more...

'Green platinum' catalyst promises cheap fuel cells, emission-free fuels

Tim Radford

11th February 2016

Advanced new catalysts are poised to stimulate a clean energy revolution, writes Tim Radford. An organic replacement for the precious metal platinum would allow surplus electricity to be cheaply converted into hydrogen fuel, then burnt in low cost fuel cells to propel 'green' vehicles and generate power on demand. more...

GM 2.0? 'Gene-editing' produces GMOs that must be regulated as GMOs

Janet Cotter & Ricarda Steinbrecher

13th January 2016

The EU is considering the exclusion of gene-edited plants and animals from GM regulations, write Janet Cotter & Ricarda Steinbrecher. However gene-edited organisms clearly fall within the definition of GMOs in both European and international law. They also present real risks to the environment and human health - and must be regulated like any other GMOs. more...

How GMO lobbyists taught me we're winning

Claire Robinson / GMWatch

11th January 2016

GMO promoters enthuse about how GM crops will be able to help the poor and hungry, far in the future, writes Claire Robinson. But they are silent about the currently-planted GM crops - 99% of them herbicide-tolerant or insecticidal. Could it be because opponents of the technology are being proved right at every turn? more...

War and police? Drones, chemicals and political repression

Paul Rogers

10th January 2015

A fusion of drone systems and chemical agents is set to transform the landscape of combat for states and non-state actors alike, writes Paul Rogers. These technologies won't just be used for warfare, but for 'public order' ... suppressing riots, protests and political dissent. Forget water cannon - this is the real deal. more...

Nuclear fusion is great - gravitationally contained, and 150 million km away

Linda Pentz Gunter

9th December 2015

ITER, the elusive and multi-million dollar fusion fantasy, was yet another nuclear chimera introduced at the Paris COP21 climate talks as a 'solution' to our climate crisis, writes Linda Pentz Gunter. But the idea is pure fantasy: long before it can be made to work, if it ever can, it will have been made obsolete by harnessing the power of our giant fusion reactor in the sky: the Sun. more...

How fast can the world transition to a low-carbon energy system?

Paul N Edwards, University of Michigan

30th November 2015

As world leaders convene in Paris for the COP21 climate summit, the major task before them is to replace fossil energy generation with renewables, writes Paul N Edwards - and with the right incentives, it could happen fast. For developing countries it's different: they could skip over fossil fuels much as they have gone straight for mobile telephony. But will they seize the opportunity? more...

Li-air battery could make oil obsolete in ten years

The Ecologist

23rd November 2015

Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future. more...

Don't nuke the climate! James Hansen's nuclear fantasies exposed

Dr Jim Green

20th November 2015

NASA scientist James Hansen is heading to COP21 in Paris to berate climate campaigners for failing to support 'safe and environmentally-friendly nuclear power', writes Jim Green. But they would gladly support nuclear power if only it really was safe and environment friendly. In fact, it's a very dangerous and hugely expensive distraction from the real climate solutions. more...

An activists' guide to the 'Snooper's Charter' - and what to do about it

Paul Mobbs

12th November 2015

The recently announced Snoopers Charter 2.0 gives the state enormous powers to delve into our lives, writes Paul Mobbs. And all the more so when combined with other data to which the government has access - by simply buying it from commercial providers. If you don't like the idea, it's time to get your systems secure and shrink your digital data trail. more...

With floating platforms, offshore wind cost set to plunge

Paul Brown

11th November 2015

Floating wind turbines offer huge falls in the cost of offshore wind power, writes Paul Brown, and could be generating power in UK waters at well under the cost of new nuclear by 2020, provided adequate support. more...

Industrial wastes could capture 1Gt a year of CO2 emissions

Helena I. Gomes, Mike Rogerson & Will Mayes

15th November 2015

The world produces over a billion tonnes a year of dangerously caustic wastes, write Helena Gomes, Mike Rogerson & Will Mayes. They are currently being dumped, although they could be used to sequester a gigatonne of CO2 from the atmosphere - while also yielding minerals essential for key renewable energy technologies. more...

Batteries and renewables - believe the hype!

Helle Abelvik-Lawson / Greenpeace Energydesk

5th November 2015

What's the new 'big thing' in energy? Of course, cheap, abundant solar power is very new and very big. But to make it work on a really large scale we need to be able to store its energy to use when we need it, not just when the sun is shining. Soon the batteries will be there to make that possible - at a price we can afford. And that will be a very big thing, indeed. more...

Ban the tiny horrors in our Halloween candy!

Jaydee Hanson & Evan Bromfield / Center for Food Safety

31st October 2015

The European Parliament voted this week to regulate nano-materials in the pending EU law on novel foods, write Jaydee Hanson & Evan Bromfield. But no such moves are taking place in the US. Let's make this the last time our children are exposed to these hazardous substances in their Halloween candy! more...

Hydrogen car price breakthrough: it's the platinum

The Ecologist

14th October 2015

Hydrogen cars - and the fuel cells that drive them - are about to get a whole lot cheaper thanks to a redesign of the platinum catalyst that makes them work, writes Oliver Tickell. By inserting atom-sized holes into the precious metal's surface, its activity can be trebled. more...

Dieselgate - our wake-up call for new car technologies

Harry Hoster, Lancaster University

8th October 2015

The real lesson of Volkswagen's 'dieselgate' scandal is that we must ditch petroleum fuels, writes Harry Hoster. There's new, clean technologies just waiting to take off - and the most promising is fuel cells. They will also fit right into the new world of renewables, with surplus power from wind and solar making the hydrogen they burn. more...

Re-engineering life? The dangers of 'next generation' biofuels

Almuth Ernsting

30th September 2015

The biofuels of the future will depend on microbes, writes Almuth Ernsting: algae to produce the biomass, and fungi or bacteria to break cellulose down into useful molecules. Just one problem: wild strains aren't up to the job. So scientists are trying to genetically engineer supercharged 'synthetic biology' variants - which will inevitably enter the environment. What could possibly go wrong? more...

Hinkley Point must be stopped - even if you believe in nuclear

Chris Goodall

19th September 2015

UK support for low-carbon energy technologies is running at £250 million a year, writes Chris Goodall. Yet the government wants to throw four times more, every year for 35 years, at the Hinkley C nuclear power station, that could take almost as long to build as Salisbury Cathedral. more...

For climate's sake, let's cut food waste!

John Mandyck

17th September 2015

At least a third of the food the world grows each year goes to waste, writes John Mandyck, most of it in fields, transport and storage. The result is poor farmers, hungry people, and a massive 3.3 billion tonnes of needless CO2 emissions. It should be a key topic for action at COP21 in Paris - but so far it's not even on the agenda. more...

Golden rice: the 'GM superfood' that fell to Earth

Glenn Stone

2nd September 2015

Golden rice was once hailed as the wonder crop that 'could save a million kids year', writes Glenn Stone. But in the 15 years since that bold prediction, the carotene enhanced GMO has been held back by persistent 'yield drag' and inconclusive nutrition outcomes. It now appears unlikely ever to fulfill its early promise. more...

Growing doubts over GMO safety: a scientist's experience

Jonathan Latham

31st August 2015

Are GMOs safe? Up to a point, writes Jonathan Latham - provided you're not eating them. That's certainly not proven to be safe, indeed the hazards are numerous: protein encoding viral DNA fragments, herbicide metabolites, biotoxins whose operation is not understood, poorly conducted experiments ... and those are just the ones we know about. more...
