| 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. |

| 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. |
| Gold leaf could help diagnose viral infections in low-resource settings Posted: 12 May 2021 05:34 AM PDT Gold leaf -- gold metal hammered into thin sheets -- is used by artists and crafters to gild picture frames, artwork and clothing. Despite its luxurious appearance, the material is affordable and available at most craft stores. Now, researchers have developed gold leaf electrodes that, in combination with a CRISPR-based assay, could sensitively detect human papillomavirus (HPV) DNA in human samples. The method also could be modified to diagnose other viral infections. |
| Petting therapy dogs enhances thinking skills of stressed college students Posted: 12 May 2021 05:34 AM PDT Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new research. |
| 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. |
| When conservation work pays off: After 20 years, the Saker Falcon breeds again in Bulgaria Posted: 11 May 2021 09:39 AM PDT Considered extinct as a breeding species in the early 2000s, the Saker Falcon was recovered when the first active nest from the new history of the species in Bulgaria was discovered in 2018, built by two birds that were reintroduced back in 2015. |
| 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. |
