East Coast, US, landslide impacts from Puerto Rico to Vermont and in between      (via sciencedaily.com) 

In the U.S., we may often think of landslides as primarily a West Coast problem, mostly plaguing the mountainous terrain of California, Oregon, and Washington. New research highlights the major impacts of landslides on the U.S. East Coast and what is being done to save lives and deal with the damages.

Recovering tropical forests offset just one quarter of carbon emissions from new tropical deforestation and forest degradation      (via sciencedaily.com) 

A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.

Bird flu associated with hundreds of seal deaths in New England in 2022      (via sciencedaily.com) 

Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.

New study finds early warning signs prior to 2002 Antarctic ice shelf collapse      (via sciencedaily.com) 

In 2002, an area of ice about the size of Rhode Island dramatically broke away from Antarctica as the Larsen B ice shelf collapsed. A new study of the conditions that led to the collapse may reveal warning signs to watch for future Antarctic ice shelf retreat, according to a new scientists.

Humans are leaving behind a 'frozen signature' of microbes on Mount Everest      (via sciencedaily.com) 

Thanks to technological advances in microbial DNA analysis, researchers have discovered that mountaineers' boots aren't the only things leaving footprints on the world's tallest mountain. When someone sneezes on Everest, their germs can last for centuries.

High winds can worsen pathogen spread at outdoor chicken farms      (via sciencedaily.com) 

A study of chicken farms in the West found that high winds increased the prevalence of Campylobacter in outdoor flocks, a bacterial pathogen in poultry that is the largest single cause of foodborne illness in the U.S. Researchers found that about 26% of individual chickens had the pathogen at the 'open environment' farms in the study, which included organic and free-range chicken farms. High winds the week prior to sampling and the farms' location in more intensive agricultural settings were linked to a greater prevalence of Campylobacter.

Climate change alters a human-raptor relationship      (via sciencedaily.com) 

Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this 'win-win' relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.

Thousands of native plants are unphotographed, and citizen scientists can help fill the gaps      (via sciencedaily.com) 

New research finds almost 4000 Australian plant species have not been photographed before in the wild, which may lead to their extinction.

Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought      (via sciencedaily.com) 

A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.

Minke whales are as small as a lunge-feeding baleen whale can be      (via sciencedaily.com) 

A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.

Brown widow spiders' aggression likely driver of black widow decline      (via sciencedaily.com) 

Black widow spiders have earned a fearsome reputation for their venomous bite. But in parts of the southern United States these spiders have much to fear themselves -- from spider relatives who really don't like their company. In the past couple decades, researchers have noticed black widow spiders being displaced by the brown widow, a fellow species in the same genus. But new research suggests this isn't a simple case of one species winning the competition for food or habitat. Instead, a study shows brown widow spiders have a striking propensity to seek out and kill nearby black widows.

Looking for risky viruses now to get ahead of future pandemics      (via sciencedaily.com) 

Rather than let the next outbreak take the world by surprise, two virologists say that the scientific community should invest in a four-part research framework to proactively identify animal viruses that might infect humans.

Remarkable squirting mussels captured on film      (via sciencedaily.com) 

Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.

Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems      (via sciencedaily.com) 

An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.

Migratory birds take breaks to boost their immune system      (via sciencedaily.com) 

Exercising too much and not getting enough rest is likely bad for your health. A new study shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.

Diverse approach key to carbon removal      (via sciencedaily.com)     Original source 

Researchers find that 10 gigatons of carbon dioxide may need to be pulled from Earth's atmosphere and oceans annually to limit global warming to 1.5 degrees. A diverse suite of carbon dioxide removal methods will be key.

The world's atmospheric rivers now have an intensity ranking like hurricanes      (via sciencedaily.com) 

Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.
