AI helps medical professionals read confusing EEGs to save lives      (via sciencedaily.com)     Original source 

Researchers have developed an assistive machine learning model that greatly improves the ability of medical professionals to read the electroencephalography (EEG) charts of intensive care patients. Because EEG readings are the only method for knowing when unconscious patients are in danger of suffering a seizure or are having seizure-like events, the computational tool could help save thousands of lives each year.

Electrochromic films -- like sunglasses for your windows?      (via sciencedaily.com)     Original source 

Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Like eyeglasses that darken to provide sun protection, the optical properties of these transparent films can be tuned with electricity to block out solar heat and light. Now, researchers report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.

Risky path to meeting climate targets for Stockholm      (via sciencedaily.com)     Original source 

The Swedish capital Stockholm aims to capture more carbon dioxide than is emitted by 2030. Therefore, the city is investing in new technology at a combined heat and power plant. But it is a strategy that has been adopted without sufficient discussion of the risks.

What makes some plant groups so successful?      (via sciencedaily.com)     Original source 

Researchers involved in cataloguing the world's plant species are hunting for answers as to what makes some groups of plants so successful. One of their major goals is to predict more accurately which lineages of flowering plants -- some of which are of huge importance to people and to ecosystems -- are at a greater risk from global climate change.

Aerosol pollution, greenhouse gases must be reduced simultaneously to keep forest fires in check      (via sciencedaily.com)     Original source 

If we want cleaner air, fewer forest fires, and less severe climate change, a new study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.

Some species may tolerate climate change better than expected      (via sciencedaily.com)     Original source 

A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.

Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally      (via sciencedaily.com)     Original source 

A new study concludes that nearly half of the food waste, about 620 million metric tons, could be eliminated by fully refrigerated food supply chains worldwide. At the same time, fully refrigerated supply chains, or 'cold chains,' could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally, according to a new study.

Prenatal exposure to air pollution associated with increased mental health risks      (via sciencedaily.com)     Original source 

A baby's exposure to air pollution while in the womb is associated with the development of certain mental health problems once the infant reaches adolescence, new research has found. The study examined the long-term mental health impact of early-life exposure to air and noise pollution.
