Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers      (via sciencedaily.com)     Original source 

Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.

Melting ice falling snow: Sea ice declines enhance snowfall over West Antarctica      (via sciencedaily.com)     Original source 

As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise.

Shark fear: Just when you thought it was safe to get back in the water...      (via sciencedaily.com)     Original source 

It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.

Non-native species likely to continue spreading in North America, Australia and Europe      (via sciencedaily.com)     Original source 

Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.

Study sheds light on how Earth cycles fossil-carbon      (via sciencedaily.com)     Original source 

Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown persist across the different geographical profiles of a river basin.

Faster Arctic warming hastens 2C rise by eight years      (via sciencedaily.com)     Original source 

The Arctic is currently warming nearly four times faster than the global average rate. The new study aimed to estimate the impact of this faster warming on how quickly the global temperature thresholds of 1.5C and 2C, set down in the Paris Agreement, are likely to be breached.

Some of today's earthquakes may be aftershocks from quakes in the 1800s      (via sciencedaily.com)     Original source 

In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.

A 'fish cartel' for Africa could benefit the countries, and their seas      (via sciencedaily.com)     Original source 

Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, researchers say African fisheries would not just secure more competitive access fees, they could also protect their seas' biodiversity.

Endangered turtle population under threat as pollution may lead to excess of females being born      (via sciencedaily.com)     Original source 

Researchers find exposure to heavy metals cadmium and antimony and certain organic contaminants, accumulated by the mother and transferred to her eggs, may cause embryos to be feminized in green sea turtles (Chelonia mydas), a species already at risk of extinction from a current lack of male hatchlings.

Second-most distant galaxy discovered using James Webb Space Telescope      (via sciencedaily.com)     Original source 

The second- and fourth-most distant galaxies ever observed have been discovered in a region of space known as Pandora's Cluster, or Abell 2744, using data from NASA's James Webb Space Telescope.

Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years      (via sciencedaily.com)     Original source 

A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.

Scientists caution against a reliance on mechanical devices to clear water bodies of plastic      (via sciencedaily.com)     Original source 

An international group of scientists has called for the United Nations Treaty on Plastic Pollution to focus more on measures to reduce the production and consumption of plastics and the prevention of future plastic waste, rather than on the unselective removal of waste already in the water.

Greenland's glacier retreat rate has doubled over past two decades      (via sciencedaily.com)     Original source 

A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.

Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics      (via sciencedaily.com)     Original source 

A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.

A different take on phosphorus: Bacteria use organic phosphorus and release methane in the process      (via sciencedaily.com)     Original source 

Some bacteria are able to tap into unusual sources of nutrients in the surface water of the oceans. This enables them to increase their primary production and extract more carbon dioxide from the atmosphere. In doing so, however, they release the potent greenhouse gas methane.

New dates for landslides reveal past Seattle fault earthquakes      (via sciencedaily.com)     Original source 

New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago -- and may also hold traces of older earthquakes along the fault.
