| Study finds six degrees celsius cooling on land during the last Ice Age Posted: 12 May 2021 11:36 AM PDT Researchers show that prior studies have underestimated the cooling in the last glacial period, which has low-balled estimates of the Earth's climate sensitivity to greenhouse gases. The rather high climate sensitivity is not good news regarding future global warming, which may be stronger than expected using previous best estimates. |
| Prehistoric horses, bison shared diet Posted: 12 May 2021 08:56 AM PDT Researchers found that a broader diversity of plants in the Arctic 40,000 years ago supported both more -- and more diverse -- big animals like horses, bison and ground sloths. The research could inform conservation of wood bison in Alaska. |
| Engineered bacteria show promise for sustainable biofuel industry Posted: 12 May 2021 08:56 AM PDT Acetone, a volatile solvent used for everything from removing nail polish and cleaning textiles to manufacturing plastics, could get a sustainability boost from a new strain of engineered bacteria. |
| An enzyme system for the hydrogen industry Posted: 12 May 2021 08:55 AM PDT An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer. |
| Study of ancient corals in Indonesia reveals slowest earthquake ever recorded Posted: 12 May 2021 05:34 AM PDT A 'slow-motion' earthquake lasting 32 years - the slowest ever recorded - eventually led to the catastrophic 1861 Sumatra earthquake, researchers have found. |
| Residential coal use in China results in many premature deaths, models indicate Posted: 12 May 2021 05:34 AM PDT Coal combustion by power plants and industry pollutes the air, causing many governments to implement mitigation actions and encourage cleaner forms of energy. Now, a new study indicates that in China, indoor air pollution from residential coal burning causes a disproportionate number of premature deaths from exposure to tiny, inhalable pollutants. |
| Nature has enormous potential to fight climate change and biodiversity loss in the UK Posted: 11 May 2021 05:11 PM PDT A new report details how nature can be a powerful ally in responding to the twin crises of biodiversity loss and climate change. |
| Posted: 11 May 2021 09:39 AM PDT The most energetic earthquakes occur where oceanic plates submerge beneath continental plates during plate tectonics. Quakes in these subduction zone settings commonly carry the risk of triggering severe tsunamis. But when the earth shook with a moment magnitude of 8.1 near the northern Chilean city of Iquique on 1 April 2014, the resulting tsunami was relatively small. A unique seismological data set provides a possible explanation. |
| Zoo YouTube videos prioritize entertainment over education Posted: 11 May 2021 09:38 AM PDT YouTube channels run by zoos focus on entertainment over education, according to a new study. |
| Bone-deep: Mineral found in human bone can help fight toxic organic compounds Posted: 11 May 2021 09:38 AM PDT Many industrial processes emit volatile organic compounds (VOCs) that are hazardous to human health. In a new study, scientists tailor the catalytic activity of hydroxyapatite, a mineral contained in human bones, using mechanical stress. This method was inexpensive and resulted in a 100% VOC conversion. |
| Nature draws out a happy place for children Posted: 11 May 2021 09:38 AM PDT Young children in deprived areas see nature and outdoor spaces as being associated with 'happy places', according to a new study. |
| Roads pose significant threat to bee movement and flower pollination Posted: 11 May 2021 09:37 AM PDT Road networks extend some 20 million miles across the globe, and that number is projected to increase by an additional 15 million miles or so by 2050. |
| COVID-19 wastewater testing proves effective in new study Posted: 11 May 2021 09:37 AM PDT The research offers some of the first clear guidance on the most effective methods to perform testing to detect COVID-19 in wastewater. |
| Sequencing the genome of the leopard Posted: 11 May 2021 09:37 AM PDT They are some of the most beautiful, and elusive, animals on the plant. Leopards. In a major scientific step, the whole genome DNA sequence of 23 individual leopards have been interpreted. |
| Box fan air cleaner can greatly reduce virus transmission, study finds Posted: 11 May 2021 09:36 AM PDT A systematic modeling study of simple air cleaners using a box fan shows these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately. |
| Mediterranean turtles recovering at different rates Posted: 10 May 2021 04:25 PM PDT Numbers of two Mediterranean turtle species have risen in the last three decades - but in Cyprus the recoveries are happening at different rates, new research shows. |
| Pretty plants hog research and conservation limelight Posted: 10 May 2021 08:35 AM PDT New research has found a bias among scientists toward colorful and visually striking plants, means they are more likely to be chosen for scientific study and benefit from subsequent conservation efforts, regardless of their ecological importance. |
| Conservationists concerned about illegal hunting and exploitation of porcupines in Indonesia Posted: 10 May 2021 07:44 AM PDT Porcupines are being illegally hunted and exploited throughout their range in Indonesia for local subsistence and commercial trade. They are reportedly in decline, yet there seems to be little control or monitoring on uptake and trade. A new study examining seizure data of porcupines in Indonesia found a total of 39 incidents from January 2013 to June 2020 involving an estimated 452 porcupines. |
| Why do more than 100 killer whales gather off Western Australia every year? Posted: 10 May 2021 07:44 AM PDT Biologists have finally fathomed why large numbers of killer whales gather at a single main location off the Western Australian southern coastline every summer. A physical oceanographer describes the conditions which have produced this ecological natural wonder of orcas migrating to the continental slope near Bremer Bay in the western Great Australian Bight from late austral spring to early autumn (January-April). |
