| Wind and solar could power the world’s major countries most of the time Posted: 05 Nov 2021 10:46 AM PDT With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources. |
| How cells correctly choose active genes Posted: 05 Nov 2021 10:46 AM PDT It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers have now found that the formation of transcription factories resembles the condensation of liquids. Their findings will improve the understanding of causes of diseases and advance the development of DNA-based data storage systems. |
| Comparing photosynthetic differences between wild and domesticated rice Posted: 05 Nov 2021 10:46 AM PDT In a new study, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity. |
| Lighting up chemical reactions for sustainable drug production Posted: 05 Nov 2021 10:45 AM PDT Researchers have discovered a new approach for using visible-light to structurally modify bioactive molecules in chemical reactions, providing a possible sustainable alternative to traditional methods that could be used in the design and production of new medicines. |
| Increasingly frequent wildfires linked to human-caused climate change Posted: 05 Nov 2021 08:43 AM PDT A new study strengthens the case that climate change has been the main cause of the growing amount of land in the western U.S. destroyed by large wildfires. And researchers say the trend is likely to worsen. |
| Save the planet (and your health) by steering clear of sweets and pastries Posted: 05 Nov 2021 07:38 AM PDT Need another reason to cut back on sugary foods and drinks, apart from an expanding waistline? They're not helping the environment, contributing to a higher cropland, water scarcity and ecological footprint, according to a new review. |
| Researchers detect a diffusion barrier inside fly brain Posted: 05 Nov 2021 07:37 AM PDT A team of researchers has now demonstrated the existence of an internal diffusion barrier in the brain of fruit flies - in addition to the already known blood-brain barrier. |
| SARS-CoV-2 variant detected in dogs and cats with suspected myocarditis Posted: 05 Nov 2021 05:41 AM PDT A new study reveals that pets can be infected with the alpha variant of SARS-CoV-2, which was first detected in southeast England and is commonly known as the UK variant or B.1.1.7. |
| New insights into kidney disease with tropical frog models Posted: 05 Nov 2021 05:41 AM PDT Using cutting-edge genetic engineering, researchers have developed a model to study hereditary kidney disease with the help of tropical frogs. The method allows them to collect large amounts of data on anomalies, which can then be analyzed using artificial intelligence. The research opens up new opportunities in the search for new treatment approaches for the hitherto incurable disease. |
| Bood metabolites associated with coffee consumption may affect kidney disease risk Posted: 04 Nov 2021 02:12 PM PDT Researchers have identified several metabolites in the blood whose levels are altered by coffee consumption. Levels of 3 of these coffee-related metabolites were significantly associated with individuals' risk of developing chronic kidney disease. |
| Repurposing carbon dioxide may be key to net-zero emissions Posted: 04 Nov 2021 01:26 PM PDT While only a mere 4% of the atmosphere, carbon dioxide plays a vital role in sustaining life on our planet. However, if this delicate balance is disrupted, excess carbon dioxide can pose a formidable threat to our environment and the living beings that reside within. |
| Radiocarbon is key to understanding Earth’s past Posted: 04 Nov 2021 11:08 AM PDT Radiocarbon records are critical to understanding the history of Earth's climate, magnetic field, and the Sun's activity, say researchers. |
| What sponges can tell us about the evolution of the brain Posted: 04 Nov 2021 11:08 AM PDT What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don't have brains, what is the role of these? Scientists imaged the sponge digestive chamber to find out. |
| Cutting ammonia emissions is a cost-effective way to prevent air pollution deaths Posted: 04 Nov 2021 11:07 AM PDT Tackling pollution from the emission of nitrogen compounds, particularly ammonia, could reduce many of the 23.3 million years of life that were lost prematurely across the world in 2013 due to nitrogen-related air pollution, an international study has discovered using a modeling framework. |
| Lake’s radioactivity concentration predicted for 10,000 days after the Fukushima accident Posted: 04 Nov 2021 08:53 AM PDT Researchers investigated the long-term contamination of Lake Onuma in Japan resulting from the 2011 Fukushima Daiichi nuclear disaster. They devised a formula based on a framework known as the fractional diffusion model to predict the radioactive contamination of the lake for up to about 30 years after the Fukushima accident. The results suggest that the decrease in radioactivity concentration will be slower than predicted by the conventional two-component decay function model. |
| Novel tag provides first detailed look into goliath grouper behavior Posted: 04 Nov 2021 07:06 AM PDT A new study reveals detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera and a hydrophone, researchers show how this species navigates through complex artificial reef environments, maintain themselves in high current areas, and how much time they spend in different cracks and crevices -- none of which would be possible without the tag. |
| Ecosystems worldwide are disrupted by lack of large wild herbivores – except in Africa Posted: 03 Nov 2021 05:26 AM PDT Biological research has repeatedly demonstrated that the relationship between the producer and the consumer is governed by a scaling law. An international research team has now looked into whether this law of nature can be reproduced in the relationship between the production of plants in an area and the number of large herbivores that graze on them. The study reveals that Africa is the only continent where the scaling law holds true. |
