To navigate the world, we all shimmy like these electric fish      (via sciencedaily.com)     Original source 

An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.

Algae's surprising potential to help ease climate change worries      (via sciencedaily.com)     Original source 

The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.

On the trail of the silver king: Researchers reveal unprecedented look at tarpon migration      (via sciencedaily.com)     Original source 

New research unveils a dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. The work leveraged networks of thousands of acoustic receivers that tracked 200 tarpon over more than five years. One of the key findings is that there are two distinct subgroups of tarpon, which has immediate implications for efforts to conserve the fish, known to anglers as the 'Silver King.'

Report warns about risk tipping points with irreversible impacts on people and planet      (via sciencedaily.com)     Original source 

A new report finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed.  The Interconnected Disaster Risks Report 2023 warns of six risk tipping points ahead of us: Accelerating extinctions; Groundwater depletion; Mountain glaciers melting; Space debris; Unbearable heat; and an Uninsurable future.

Diapers can be recycled 200 times faster with light      (via sciencedaily.com)     Original source 

More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.

Bitcoin mining has 'very worrying' impacts on land and water, not only carbon      (via sciencedaily.com)     Original source 

As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.

Light, freshwater sticks to Greenland's east coast      (via sciencedaily.com)     Original source 

Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island.  In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.

Climate is increasing risk of high toxin concentrations in Northern US lakes      (via sciencedaily.com)     Original source 

As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.

A step on the way to solid-state batteries      (via sciencedaily.com)     Original source 

A lithium ceramic could act as a solid electrolyte in a more powerful and cost-efficient generation of rechargeable lithium-ion batteries. The challenge is to find a production method that works without sintering at high temperatures. A research team has now introduced a sinter-free method for the efficient, low-temperature synthesis of these ceramics in a conductive crystalline form.

Land use: Producing more food and storing more carbon      (via sciencedaily.com)     Original source 

Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.

DNA shows where Washington culvert replacements helped spawning salmon      (via sciencedaily.com)     Original source 

University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.

Scientists discover deepest known evidence of coral reef bleaching      (via sciencedaily.com)     Original source 

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
