Potential changes in the frequency and intensity of storms off the coast of the UK and around the world could have a “catastrophic impact” on the livelihood of fishermen and sustainability of fishing industries, research led by the University of Exeter has shown.

The research, based on a review of past studies and examination of future projections, warns that the increase in storms could make fishing more dangerous, displace fish from their natural habitats and interfere with the ability of fish to breed.

Storms off the coast of the UK are projected to become more frequent and intense over the next two centuries and more dramatic storms are expected in the North Sea and North Atlantic, to the West of the UK, Ireland and France, threatening the future of fishermen and the fish they catch.

Covering roofs and walls of buildings with vegetation is a good way of reducing greenhouse gas emissions. And these green roofs and walls make cities look nicer. Toronto’s central business district adopted a policy of establishing green roofs on around half of all city buildings in 2009. Research shows this could reduce maximum city temperatures by up to 5℃.

We spent the past 12 months analysing the case for more greenery on Australian city buildings, drawing on international comparisons. We’ve shown that a mandatory policy, coupled with incentives to encourage new and retrofitted green roofs and walls, will provide environmental, social and business benefits.

These include improved air quality, energy conservation and reductions in stormwater run-off from buildings, which would decrease flash flooding. Green roofs and walls also become new habitats for biodiversity and can be pleasant spaces for social interaction in dense urban areas.

On May 20, China launched Queqiao, a lunar communications relay satellite for the upcoming Chang’e 4 lander and rover mission. On the way out to the Moon, it dropped off a pair of small satellites bound for lunar orbit called Longjiang-1 and Longjiang-2. The satellites weigh just 45 kilograms each and measure 50-by-50-by-40 centimeters. Their purpose is testing out future radio astronomy and interferometry techniques, and one also has a camera built by Saudi Arabia.

Unfortunately, Longjiang-1 had a problem and didn’t make it into lunar orbit. Longjiang-2, however, was successful, and sent home a few pictures! Check them out:

A Dutch construction company is about to 3D print five actually habitable homes near the city of Eindhoven. But can the technique replace brick and mortar?

Too bad the middle class is shrinking!

The rate of growth in residential rooftop solar photovoltaics (PV) in Australia since 2008 has been nothing short of breathtaking.

Our new research suggests that the households most likely to join in the solar spree are those that are affluent enough to afford the upfront investment, but not so wealthy that they don’t worry about their future power bills.

Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight.

The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

“There is nothing like this,” said Omar Yaghi, who invented the technology underlying the harvester. “It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.”

“Society is vulnerable, so we need to prepare ourselves as individuals,” said Dan Eliasson of the Swedish civil contingencies agency, which is in charge of the project. “There’s also an information deficit in terms of concrete advice, which we aim to provide.”

Update from a space robot rolling around Mars!

Sols 5073–5102

Opportunity continued exploring the south trough of Perseverance in May, still looking for evidence that explains just how this one-of-a-kind valley meandering through Endeavour Crater’s rim formed, and, along the way, helped the Mars Exploration Rover (MER) mission chalk up yet another first, linking with three relay orbiters in one Martian day or sol to send a pipeline of data home.
