| Early molten moon’s deep secrets Posted: 03 Aug 2021 02:52 PM PDT Recently, a pair of NASA studies identified the most likely locations to find pieces of the Moon's mantle on the surface, providing a map for future lunar sample return missions such as those under NASA's Artemis program. If collected and analyzed, these fragments from deep within the Moon can provide a better understanding of how the Moon, the Earth, and many other solar system worlds evolved. |
| How landscapes of fear affect the songbirds in our backyards Posted: 03 Aug 2021 02:52 PM PDT A team of researchers has recently discovered that fear plays an important, unrecognized role in the underdevelopment, and increased vulnerability, of backyard songbirds. |
| New approach opens window into life below the seafloor Posted: 03 Aug 2021 02:52 PM PDT Scientists studied microorganisms from an underwater mountain in the Atlantic Ocean, pioneering a method that could open new windows into our understanding of how life survives deep under the sea -- or in space. |
| State of the science on western wildfires, forests and climate change Posted: 03 Aug 2021 02:52 PM PDT Seeing the urgent need for change, a team of scientists from leading research universities, conservation organizations and government laboratories across the West has produced a synthesis of the scientific literature that clearly lays out the established science and strength of evidence on climate change, wildfire and forest management for seasonally dry forests. The goal is to give land managers and others across the West access to a unified resource that summarizes the best-available science so they can make decisions about how to manage their landscapes. |
| Emperor penguins increasingly threatened by climate change Posted: 03 Aug 2021 09:13 AM PDT A new study provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice loss. |
| Semi-natural habitat patches complement flower strips in protecting pollinators Posted: 03 Aug 2021 09:13 AM PDT Ecologists observe the diversity of insects on the edge of apple orchards on Lake Constance. |
| What’s killing coral reefs in Florida is also killing them in Belize Posted: 03 Aug 2021 07:55 AM PDT Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly driving macroalgal blooms to increase on the Belize Barrier Reef and causing massive decline in hard coral cover. With only 2 percent of hard coral cover remaining in the Florida Keys National Marine Sanctuary, it's too late to save that reef, but there's still hope for the Belize Barrier Reef. |
| New method to detect impact of sea level rise Posted: 03 Aug 2021 07:55 AM PDT Scientists have developed a new simple, inexpensive and fast method to analyze sulfur isotopes, which can be used to help investigate chemical changes in environments such as oceans, and freshwater rivers and lakes. |
| Productivity of kelp forests, sans the iconic kelp Posted: 02 Aug 2021 01:06 PM PDT A lush canopy is a defining feature of most of the planet's forests. But canopy-forming species can be particularly vulnerable to disturbances and environmental change. So the question is: What is a forest without its trees? |
| Manganese could make luminescent materials and the conversion of sunlight more sustainable Posted: 02 Aug 2021 08:49 AM PDT Researchers have reached an important milestone in their quest to produce more sustainable luminescent materials and catalysts for converting sunlight into other forms of energy. They have developed a new class of compounds, based on the cheap metal manganese, with promising properties that until now have primarily been found in noble metal compounds. |
| Bird and mammal diversity is declining with biological invasions Posted: 02 Aug 2021 07:30 AM PDT The introduction of invasive species leads to a decline in certain native species: a team of researchers has managed to show that 11% of the global phylogenetic diversity of birds and mammals, in other words their accumulated evolutionary history, is threatened by biological invasions. Their ability to adapt to environmental changes could thus be largely lost due to biological invasions. |
