Five key lessons other cities can learn from Cape Town’s water crisis

Posted by in categories: climatology, sustainability

Postponing Day Zero in Cape Town for 2018 comes as no surprise. There was no sense to it once the day had been pushed into the winter rainfall period. It also didn’t make sense for the Western Cape and Cape Town governments to continue drafting detailed logistical plans for points of water distribution in the event that taps were turned off across the city.

But Cape Town’s remain at high risk because the long-term predictions for rainfall in the south-western Cape remain uncertain. Dam levels continue to fall while people are struggling to achieve the ’s target of 450 million litres per day. And yields from new water schemes will only be known in the coming months and next year.

The general perception is that the onset of climate change would be slow and measured. This would afford authorities the time to intervene with considered plans. But climate change is a disrupter and takes no prisoners. Over the past three years, Cape Town and the surrounding regions has experienced successive years of well below average rainfall. The experience is changing the way people think about water and how it is managed.

Research overcomes major technical obstacles in magnesium-metal batteries

Posted by in categories: chemistry, energy, nanotechnology

YES!!!


Scientists at the Department of Energy’s National Renewable Energy Laboratory (NREL) have discovered a new approach for developing a rechargeable non-aqueous magnesium-metal battery.

A proof-of-concept paper published in Nature Chemistry detailed how the scientists pioneered a method to enable the reversible of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in a prototype cell. The technology possesses potential advantages over lithium-ion batteries—notably, higher density, greater stability, and lower cost.

Our legacy of liveable cities won’t last without a visionary response to growth

Posted by in categories: economics, health, policy

Australia’s major cities are growing more rapidly than ever before, gaining three million residents in a decade. Concerns about the risks to their long-term liveability and health are growing too. Is the consistent placing of Australian cities at the top of most liveable city rankings a reason for complacency?

The fastest-growing city, Melbourne, is experiencing unprecedented growth and yet has topped The Economist Intelligence Unit global liveability ranking for seven years running. However, much like Australia’s remarkable record of 26 years of continuous economic growth, many of the policy and institutional reforms that delivered this liveability legacy occurred decades ago.

Australia is now undergoing its third great wave of population growth, putting pressure on infrastructure, services and the environment. During the past two waves of growth, in the late-19th and mid-20th centuries, cities implemented visionary responses. It’s largely because of these past phases of planning and investment that our cities have until now been able to sustain their liveability and a reasonably healthy natural environment.

Telematics technology steering toward smarter EU roads

Posted by in categories: climatology, economics, sustainability

If we are to have truly smart cities our transport systems will have to be more cost-effective, safer and sustainable. Perhaps most of all they will need to be more integrated, as the EU-funded project MFDS demonstrates.

The stated aim of the EU’s ‘smart, green and integrated transport’ initiative is to build a European transport that is ‘resilient, resource-efficient, climate- and environmentally friendly, safe and seamless for the benefit of all citizens, the economy and society.’

In contribution, the EU-funded MFDS project has developed a versatile and affordable ‘Intelligent Transport System’ offering several functions including wrong-way driver detection, traffic congestion detection, vehicle counting by vehicle classification and parking accounting. The core innovation of MFDS is the system’s ability to perform its functions simultaneously, while remaining low-cost to buy and install, as well as running on minimum power. The project’s feasibility study has demonstrated that the system will be of interest to multiple EU markets.

Rocket Lab sets date for first commercial launch of its Electron rocket

Posted by in category: satellites

US spaceflight startup Rocket Lab is officially open for business and has scheduled its very first commercial launch for later this month. The company will launch its small Electron rocket with payloads from two paying satellite operators on board — just three months after completing a second test flight of the vehicle. The upcoming mission will initiate the beginning of customer operations for Rocket Lab, which claims to have a busy manifest for this year and next.

After four years of developing the Electron, Rocket Lab flew the vehicle for the first time in May 2017 out of the company’s own private launch site in New Zealand. That test flight — appropriately dubbed “It’s a Test” — made it to space, though the rocket didn’t achieve orbit, due to a glitch in communication equipment on the ground. Rocket Lab was able to fix the problem, though, and performed a second test flight of the Electron in January in a mission called “Still Testing.” That time, the vehicle did make it to orbit and even deployed four satellites, including a secret disco ball probe made by Rocket Lab’s CEO Peter Beck.

Russian science chases escape from mediocrity

Posted by in categories: economics, government, science

For all its progress, Russia’s state-funded science still lags behind that of emerging science powers including China, India and South Korea, especially when it comes to translating discoveries into economic gains. Decades of underfunding, excessive state bureaucracy and entrenched opposition to reform within the country’s sputtering research institutions are hampering competitiveness, says Khokhlov. “What we need are new ideas, new labs, fresh talent and more freedom and competition.”


With Vladimir Putin set to earn another presidential term, researchers wonder whether his government will reverse decades of decline.

Neuroscientists Confirm That Our Loved Ones Become Ourselves

Posted by in category: neuroscience

A new study has confirmed that humankind’s capacity for love and friendship sets us apart from all other species. Researchers at University of Virginia have found that humans are hardwired to empathize with those close to them at a neural level.

Interestingly, the ability to put yourselves in another person’s shoes depends drastically on whether the person is a stranger or someone you know. The study titled “Familiarity Promotes the Blurring of Self and Other in the Neural Representation of Threat” appears in the August issue of the journal Social Cognitive and Affective Neuroscien ce.

According to researchers, the human brain puts strangers in one bin and the people we know in another compartment. People in your social network literally become entwined with your sense of self at a neural level. “With familiarity, other people become part of ourselves,” said James Coan, a psychology professor in University of Virginia’s College of Arts & Sciences who used functional magnetic resonance imaging brain (fMRI) scans to find that people closely correlate people to whom they are attached to themselves.

Different shades of shadow

Posted by in category: cosmology

This graphic is perhaps more complex than first meets the eye. The Sun glows hot to the left, illuminating the Earth’s surface. The side facing away from the Sun is cast in deep shadow, and the man-made lights of cities are visible. The darkest patch of shadow, where the Earth blocks all the Sun’s light, is called the umbra. The lighter slivers of shadow either side of the umbra, which are not in total darkness, is the penumbra. Needless to say, this is not to scale!

This graphic will form part of the “The Living Universe” exhibition, to be displayed at the ESO Supernova, opening in spring 2018.
