| New survey method proves Rhode Island's rarest frog may not be so rare Posted: 14 Jun 2021 03:56 PM PDT A study by researchers using a seldom-used methodology turned up many more Eastern spadefoots, an endangered primitive frog, than they expected. |
| New health benefits of red seaweeds unveiled Posted: 14 Jun 2021 03:55 PM PDT Red seaweeds have been prevalent in the diets of Asian communities for thousands of years. Researchers have now shown how these algae confer health benefits. |
| As climates change, prepare for more mosquitoes in winter Posted: 14 Jun 2021 03:55 PM PDT In places on the front lines of climate change, these disease-spreading insects may become a year-round problem. |
| 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. |
| Making a meal of DNA in the seafloor Posted: 14 Jun 2021 12:39 PM PDT While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source. One bacterium newly named by the team in fact is a true expert in degrading DNA. |
| Persistence pays off in the human gut microbiome Posted: 14 Jun 2021 12:39 PM PDT The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health -- but how is it sustained? |
| 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. |
| 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. |
| Huge prehistoric croc 'river boss' prowled waterways Posted: 14 Jun 2021 10:12 AM PDT A new species of large prehistoric croc that roamed southeast Queensland's waterways millions of years ago has been documented. |
| 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. |
| Plant-based diet protects from hypertension, preeclampsia Posted: 14 Jun 2021 08:08 AM PDT A plant-based diet appears to afford significant protection to rats bred to become hypertensive on a high-salt diet, scientists report. When the rats become pregnant, the whole grain diet also protects the mothers and their offspring from deadly preeclampsia. |
| 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). |
