Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the release of the 2018 Carnegie Mellon Power Sector Carbon Index, at CMU Energy Week, hosted by the Wilton E. Scott Institute for Energy Innovation. The Index tracks the environmental performance of U.S. power producers and compares current emissions to more than two decades of historical data collected nationwide. This release marks the one-year anniversary of the Index, developed as a new metric to track power sector carbon emissions performance trends.

“The Carnegie Mellon Power Sector Carbon Index provides a snapshot of critical data regarding energy production and environmental performance,” said Costa Samaras, Assistant Professor of Civil and Environmental Engineering. “We’ve found this index to provide significant insight into trends in power generation and emissions. In particular, the data have shown that emissions intensity has fallen to the lowest level on record, as a combination of natural gas and renewable power have displaced more carbon intensive coal-fired power generation.”

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 water supplies 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 city’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.

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 chemistry 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 energy density, greater stability, and lower cost.

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.

We could be swallowing more than 100 tiny plastic particles with every main meal, a Heriot-Watt study has revealed.

The plastic, which can come from soft furnishings and synthetic fabrics, gets into household dust which falls on plates and is consumed.

The university academics made the discovery after putting Petri dishes containing sticky dust traps on the table next to dinner plates in three homes at meal times.

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 system 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.

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.

___ Why you shouldn’t bother with memory or brain health supplements (Consumer Reports): The signs of memory loss can be bewildering and scary: misplaced keys, a forgotten street name, that task you suddenly can’t remember. It’s no wonder that, according to the Nutrition Business Journal, sales of supplements touted.

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.
