Whale remains tracked to highlight sustainable disposal benefits      (via sciencedaily.com)     Original source 

A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.

How a plant app helps identify the consequences of climate change      (via sciencedaily.com)     Original source 

A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.

Study reveals environmental impact of artificial sweeteners      (via sciencedaily.com)     Original source 

A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.

Coral reefs: Battlegrounds for survival in a changing climate      (via sciencedaily.com)     Original source 

Coral reefs, those vibrant underwater cities, stand on the precipice of collapse. While rising ocean temperatures and coral bleaching grab headlines, a new essay reveals a hidden layer of complexity in this fight for survival: the often-overlooked roles of the reefs' smallest inhabitants.

Study illuminates cues algae use to 'listen' to their environment      (via sciencedaily.com)     Original source 

New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.

Tiny bright objects discovered at dawn of universe baffle scientists      (via sciencedaily.com)     Original source 

A recent discovery by NASA's James Webb Space Telescope (JWST) confirmed that luminous, very red objects previously detected in the early universe upend conventional thinking about the origins and evolution of galaxies and their supermassive black holes.

Projected loss of brown macroalgae and seagrasses with global environmental change      (via sciencedaily.com)     Original source 

Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.

Wolves reintroduced to Isle Royale temporarily affect other carnivores, humans have influence as well      (via sciencedaily.com)     Original source 

In a rare opportunity to study carnivores before and after wolves were reintroduced to their ranges, researchers found that the effects of wolves on Isle Royale have been only temporary. And even in the least-visited national park, humans had a more significant impact on carnivores' lives.

Future risk of coral bleaching set to intensify globally      (via sciencedaily.com)     Original source 

Researchers have projected future marine heatwaves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen.

Pillars of creation star in new visualization from NASA's Hubble and Webb telescopes      (via sciencedaily.com)     Original source 

Made famous in 1995 by NASA's Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty. Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA's Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds.

Fuel treatments reduce future wildfire severity      (via sciencedaily.com)     Original source 

There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.

Star clusters observed within a galaxy in the early Universe      (via sciencedaily.com)     Original source 

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to understanding it. New insights about young galaxies during the Epoch of Reionization have been revealed. Observations with the James Webb Space Telescope (JWST) of the galaxy Cosmic Gems arc (SPT0615-JD) have confirmed that the light of the galaxy was emitted 460 million years after the big bang. What makes this galaxy unique is that it is magnified through an effect called gravitational lensing, which has not been observed in other galaxies formed during that age.

Boosting biodiversity without hurting local economies      (via sciencedaily.com)     Original source 

Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
