| Research reveals why people pick certain campsites Posted: 14 Jun 2021 03:56 PM PDT Those in love with the outdoors can spend their entire lives chasing that perfect campsite. New research suggests what they are trying to find. |
| Lightning impacts edge of space in ways not previously observed Posted: 14 Jun 2021 03:55 PM PDT A team of researchers working with data collected by an Incoherent Scatter Radar (ISR) have examined the simultaneous impacts of thunderstorms and solar flares on the ionospheric D-region (often referred to as the edge of space). |
| Microbes in ocean play important role in moderating Earth's temperature Posted: 14 Jun 2021 03:55 PM PDT A new study uncovers where much of the carbonate consumption in the deep sea is happening - a process that prevents its escape into Earth's atmosphere. Researchers collected and examined methane-eating microbes from seven geologically diverse seafloor seeps and found that the carbonate rocks from all sites host methane-oxidizing microbial communities with the highest rates of methane consumption. |
| More than a bumpy ride: Turbulence offers boost to birds Posted: 14 Jun 2021 03:55 PM PDT By combining wind speed data with the measured accelerations of a golden eagle outfitted with GPS tracking instruments, researchers suggest that, rather than hindering flight, turbulence is a source of energy that birds may use to their advantage. |
| Rocky mountain forests now burning more than any point in past 2,000 years Posted: 14 Jun 2021 12:39 PM PDT Following 2020's extreme fire season, high-elevation forests in the central Rocky Mountains now are burning more than at any point in the past 2,000 years, according to a new study. |
| Boundary of heliosphere mapped Posted: 14 Jun 2021 12:39 PM PDT For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact. |
| An unusual symbiosis of a ciliate, green alga, and purple bacterium Posted: 14 Jun 2021 12:39 PM PDT The intracellular purple sulfur bacterium 'Candidatus Thiodictyon intracellulare' has lost the ability to oxidize sulfur and now supplies a ciliate with energy from photosynthesis. |
| Climate conditions during the migration of Homo sapiens out of Africa reconstructed Posted: 14 Jun 2021 12:39 PM PDT Climate reconstruction of the last 200,000 years from East Africa illustrates the living conditions of Homo sapiens when they migrated out of Africa / Homo sapiens was mobile across regions during wet phases and retreated to high altitudes during dry phases. |
| Scientists expose the cold heart of landfalling hurricanes Posted: 14 Jun 2021 10:12 AM PDT Fearsome and powerful, hurricanes can wreak massive destruction when they hit land. But while most hurricanes then weaken, others can strengthen again into extratropical cyclones and caused further damage inland. Now, researchers have used simulations to uncover the presence of a cold core inside decaying hurricanes - an unexpected discovery that could help forecasters predict the level of extreme weather that communities farther inland may face. |
| What does it take to discover a new species of cicada? Posted: 14 Jun 2021 10:12 AM PDT An observation of an insect exoskeleton on a potted plant may lead to the identification of a new species of cicada. |
| Too many forewing eyespots are bad for butterflies Posted: 14 Jun 2021 10:12 AM PDT Biologists sought to understand the impact of uneven distribution of eyespots on butterflies. The team found that the location of these eyespots is key to their protective function. |
| Irish potato famine pathogen stoked outbreaks on six continents Posted: 14 Jun 2021 08:08 AM PDT Researchers tracking the evolution of different strains of the plant pathogen that caused the Irish potato famine in the 1840s show that the historic lineage called FAM-1 was found in nearly three-fourths of the 140 historic and modern samples tested and was found on all six continents. |
| Posted: 14 Jun 2021 08:08 AM PDT Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces. With new model calculations, they are proposing a comprehensive explanation of known sun cycles for the first time. They also reveal the longest fluctuations in activity over thousands of years as a chaotic process. |
| A better understanding of 'wet markets' is key to safeguarding human health, biodiversity Posted: 11 Jun 2021 05:56 AM PDT The term 'wet market' is often laced with negative undertones, especially in light of the COVID-19 pandemic, but the majority of these markets -- like the one featured above in Taipei, Taiwan -- pose very little risks to human health and biodiversity, according to a new study. |
| For bay oysters, protection plus restoration creates healthiest reefs Posted: 10 Jun 2021 10:57 AM PDT Actively restoring oyster reefs -- beyond simply protecting them from harvest -- can create big payoffs for habitat quality and the other species that flock to them. A new study compared restored, protected and harvested areas using photos and video footage from roughly 200 sites. |
| Posted: 10 Jun 2021 10:57 AM PDT New research shows that disruptions to Indigenous land management following Iberian colonization did not always result in widespread forest regrowth in the Americas and Asia-Pacific, as has been recently argued. |
| Declining growth rates of global coral reef ecosystems Posted: 10 Jun 2021 10:57 AM PDT If the trend of declining coral growth continues at the current rate, the world's coral reefs may cease calcifying around 2054, a new study has found. Drawing on research from the late 1960s until now, the paper reveals the global spatiotemporal trends and drivers of coral reef ecosystem growth (known as calcification). |
