Neutrinos made by a particle collider detected      (via sciencedaily.com) 

Physicists have detected neutrinos created by a particle collider. The discovery promises to deepen scientists' understanding of the subatomic particles, which were first spotted in 1956 and play a key role in the process that makes stars burn.

Jellyfish size might influence their nutritional value      (via sciencedaily.com) 

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

Inbreeding contributes to decline of endangered killer whales      (via sciencedaily.com) 

The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.

New study provides first comprehensive look at oxygen loss on coral reefs      (via sciencedaily.com) 

A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. The study captures the current state of hypoxia -- or low oxygen levels -- at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.

How fishermen benefit from reversing evolution of cod      (via sciencedaily.com) 

Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

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.

Webb Telescope captures rarely seen prelude to supernova      (via sciencedaily.com) 

The rare sight of a Wolf-Rayet star -- among the most luminous, most massive, and most briefly detectable stars known -- was one of the first observations made by NASA's James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments. The star is 15,000 light-years away in the constellation Sagittarius.

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.

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.

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.
