Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Wildfires increasingly threaten oil and gas drill sites, compounding potential health risks
(via sciencedaily.com) Original source More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of fires worsened by climate change.
Published Fuel treatments reduce future wildfire severity
(via sciencedaily.com) Original source There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
Published New study finds dinosaur fossils did not inspire the mythological griffin
(via sciencedaily.com) Original source For centuries, scientists thought they knew where the griffin legend came from. A new study takes a closer look at the data and folklore's influence on science.
Published Newly discovered dinosaur boasts big, blade-like horns
(via sciencedaily.com) Original source A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published Large wildfires create weather that favors more fire
(via sciencedaily.com) Original source A new study shows soot from large wildfires in California traps sunlight, making days warmer and drier than they ought to be.
Published Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere
(via sciencedaily.com) Original source An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.
Published New way to spot beetle-killed spruce can help forest, wildfire managers
(via sciencedaily.com) Original source A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.
Published Fighting fires from space in record time: How AI could prevent devastating wildfires
(via sciencedaily.com) Original source Scientists are getting closer to detecting bushfires in record time, thanks to cube satellites with onboard AI now able to detect fires from space 500 times faster than traditional on-ground processing of imagery.
Published Novel mobile air monitoring technology yields greater insight into post-disaster pollution levels
(via sciencedaily.com) Original source A team has found that high resolution mass spectrometry could be a valuable tool for identifying and assessing air-borne contaminants produced by natural and human-made disasters.
Published Origins of 'Welsh dragons' finally exposed by experts
(via sciencedaily.com) Original source A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
Published Musankwa sanyatiensis, a new dinosaur from Zimbabwe
(via sciencedaily.com) Original source Fossils found on the shoreline of Lake Kariba in Zimbabwe represent a completely new dinosaur species. This remarkable find, named Musankwa sanyatiensis, marks only the fourth dinosaur species named from Zimbabwe.
Published 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.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Researchers discover hidden step in dinosaur feather evolution
(via sciencedaily.com) Original source Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.
Published First 'warm-blooded' dinosaurs may have emerged 180 million years ago
(via sciencedaily.com) Original source The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
Published Improved wildfire smoke model identifies areas for public health intervention
(via sciencedaily.com) Original source The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
Published T. Rex not as smart as previously claimed
(via sciencedaily.com) Original source Dinosaurs were likely as smart as reptiles but not as intelligent as monkeys.
