The aquaculture sector is growing, with fish farming being a key way to ensure Europe gets the quality food it needs without exploiting marine resources further. One key problem the industry faces is how to get the immature fish though their first few months – one EU project may be about to smooth the way.

Aquaculture is a growing market within the EU, bringing employment and providing a sustainable source of fish at a time when our marine life is under pressure. The main bottle-neck for the production of marine fish is the juvenile phase, especially during the time in which live diets are used. Even the established species, sea bream and sea bass, have a very low survival rate with an average of 25 percent. For new species in aquaculture, such as amberjack and tuna, the mortality is even higher.

The natural first feed for most fish larvae is crustacean nauplii, the offspring of many types of crustacean zooplankton. Fish larvae is evolutionary adapted to such a diet, and it is believed that this type of prey fulfils the fish larva’s nutritional requirements.

The German engineering company Geltz Umwelt-Technologie has successfully developed an advanced recycling plant for obsolete or ageing solar panels.

As sales of solar power increase, there is a looming problem that is quite often overlooked: disposing waste from outdated or destroyed solar panels. A surge in solar panel disposal is expected to take place in the early 2030s, given the design life of solar energy systems installed around the millennium.

To address this problem before this big disposal wave, the EU has funded the ELSi project. With strong competencies in plant manufacturing and wastewater treatment including recycling, the Geltz Umwelt-Technologie firm has built a test and treatment facility at a large disposal firm to retrieve reusable materials from solar modules.

Imagine something similar to the Great Depression of 1929 hitting the world, but this time it never ends.

Economic modelling suggests this is the reality facing us if we continue emitting greenhouse gases and allowing temperatures to rise unabated.

Economists have largely underestimated the global economic damages from climate change, partly as a result of averaging these effects across countries and regions, but also because the likely behaviour of producers and consumers in a climate change future isn’t usually taken into consideration in climate modelling.

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO₂ from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO₂. This work is presented at the Goldschmidt conference in Boston.

Scientists are already working to slow global warming by removing carbon dioxide from the atmosphere, but there are serious practical and economic limits on developing the technology. Now, for the first time, researchers have explained how magnesite forms at low temperature, and offered a route to dramatically accelerating its crystallization. A tonne of naturally-occurring magnesite can remove around half a tonne of CO₂ from the atmosphere, but the rate of formation is very slow.

Project leader, Professor Ian Power (Trent University, Ontario, Canada) said:

A research analyst at Swiss investment bank UBS believes the cost of energy renewables could be so near to zero by 2030 “it will effectively be free,” according to a projections published on Monday. If renewables could soon be cheaper than all the alternative energy sources, and that this “is great news for the planet, and probably also for the economy.”

The analysis, published in the Financial Times, explains that solar and wind farms are getting bigger, and that the potential of this sort of cheap, green energy is far-reaching and will only get cheaper. “In 2010, using solar power to boil your kettle would have cost you about £0.03,” the analyst writes in FT. “By 2020, according to estimates by our research team at UBS, the cost will have fallen to half a penny.” And just ten years later, the costs will be so minuscule, it will practically be free.

Historically, water managers throughout the thirsty state of California have relied on hydrology and water engineering—both technical necessities—as well as existing drought and flood patterns to plan for future water needs.

Now, climate change is projected to shift water supplies as winters become warmer, spring snowmelt arrives earlier, and extreme weather-related events increase. Some water utilities have started to consider these risks in their management, but many do not. Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new University of California, Davis, paper suggests.

The paper, which analyzes various approaches to climate science by drinking water utility managers in California, was presented along with new research at the American Sociology Association Conference in Philadelphia on Aug. 11. The paper, “Climate Information? Embedding Climate Futures within Social Temporalities of California Water Management,” was published this spring in the journal Environmental Sociology.

Just as Henry Ford’s assembly line revolutionized the automobile industry, synthetic biology is being revolutionized by automated DNA assembly (see SynBioBetaLive! with Opentrons). The key features of an assembly line translate well into the field of synthetic biology – speed, accuracy, reproducibility and validation. Instead of welding chassis together, small robotic arms are lifting delicate plates holding dozens of samples, adding and removing miniscule amounts of fluid.

While Facebook and Google recently pulled the plug on their solar-powered internet drones, another company with a lot more experience is having success with the idea. Airbus announced that its solar-powered Zephyr S HAPS (high altitude pseudo-satellite) flew for 25 straight days, setting a time aloft record for any airplane, ever. It shattered the previous record of 14 days, marked by a previous prototype Zephyr aircraft.

The Zephyr flies on sun power alone at over 70,000 feet, an altitude that just a few aircraft like the Concorde and SR-71 Blackbird have reached. That’s well above any weather, and lets it perform reconnaissance, surveillance and communications/internet duties. “[It fills a] capability gap complimentary to satellites, UAVs and manned aircraft to provide persistent local satellite-like services,” Airbus said in a press release. A video of the takeoff (below) shows that it can be lifted and launched by hand. Once aloft, it can be operated for a fraction the cost of a satellite.

Wealth-generating, flat-pack solar houses and a profit-sharing scheme that incentivises retrofitting are bringing sustainable living to people who would otherwise not be able to afford it.

“One of the biggest problems that we see right now is (the creation of) a big gap between the lower and the middle classes. Everyone is talking about this growing inequality gap,” said Bart Glowacki, co-founder of SOLACE, a start-up based in Warsaw, Poland, set up with the aim of making sustainable housing widely affordable.

Tighter mortgage controls, job insecurity and high student debts in Europe has meant that it is increasingly difficult for young people to buy their own homes.
