Advanced Micro Devices Inc. and Nvidia Corp. are feeling the heat from a Chinese adversary that they never imagined would become a competitor.

How many times have you heard someone say that the pursuit of beauty, or of its preservation over time, is a “vain” endeavor? My guess would be probably many. That’s why you need to tread carefully if you plan to present the preservation of looks as an argument in favor of rejuvenation biotechnology—you might be stepping into a minefield.

Quite frankly, I never got what’s so wrong with wanting to maintain youthful beauty over time, and I’d tend to think we’re dealing with a fox-and-grapes situation here.

Neural networks have started to take off since AlexNet in 2012. We don’t have to call it a software war, but there’s a competition for mindshare and community contributors in neural networks.

Of course, AI needs more than a neural network library, it needs the configuration hyperparameters, training datasets, trained models, test environments, and more.

Most people have heard of Google’s Tensorflow which was released at the end of 2015, but there’s an active codebase called PyTorch which is easier to understand, less of a black box, and more dynamic. Tensorflow does have solutions for some of those limitations (such as Tensorflow-fold, and Tensorflow-Eager) but these new capabilities remove the need for other features and complexity of Tensorflow. Google built a high-performance system for doing static computation graphs before realizing that most people want dynamic graphs. Doh!

In 2017, synthetic biology companies raised a record amount of funding – just over $1.8 billion for fifty two companies – driven mostly by several multi-hundred million dollar deals. This was a 50% increase over the previous year, a pace of growth that indicated an intense interest in the field from outside investors. It seems that this interest has only intensified since then, as 27 companies raised $650 million in funding during the first quarter of 2018, which is double the activity of the first quarter of 2017. At this rate, the field is on track to raise over $2.4 billion with over 100 companies being funded, which would be a record for both statistics.

The companies raising money in 2018 are pursuing a broadly diverse set of applications from all sections of the synthetic biology technology stack. Many companies are developing products that will eventually end up in the hands (or bodies) of everyday consumers, but others are making the tools and reagents that will empower the whole field to become more productive. It is important that all of these types of companies exist in order to build a healthy industry ecosystem.

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.
