Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction      (via sciencedaily.com)     Original source 

Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.

How did the Andes Mountains get so huge? A new geological research method may hold the answer      (via sciencedaily.com)     Original source 

How did the Andes -- the world's longest mountain range -- reach its enormous size? This is just one of the geological questions that a new method may be able to answer. With unprecedented precision, the method allows researchers to estimate how Earth's tectonic plates changed speed over the past millions of years.

How skates learned to fly through water      (via sciencedaily.com)     Original source 

Genes are not the only drivers of evolution. The iconic fins of skates are caused by changes in the non-coding genome and its three-dimensional structure, an international research team reports.

Humans need Earth-like ecosystem for deep-space living      (via sciencedaily.com)     Original source 

Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.

Critical observations of sinking coasts      (via sciencedaily.com)     Original source 

Using satellite-obtained data from 2007-21, researchers mapped the entire East Coast to demonstrate how the inclusion of land subsidence reveals many areas to be more vulnerable to floods and erosion than previously thought.

Pollution monitoring through precise detection of gold nanoparticles in woodlice      (via sciencedaily.com)     Original source 

Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.

Lightning strike creates phosphorus material      (via sciencedaily.com)     Original source 

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

Jellyfish and fruit flies shed light on the origin of hunger regulation      (via sciencedaily.com)     Original source 

To survive, all organisms must regulate their appetite. Hormones and small proteins called neuropeptides perform this process, stimulating feelings of hunger and fullness. When researchers noted the similarities between GAWamide, a neuropeptide that regulates feeding in the Cladonema jellyfish, and myoinhibitory peptide, a neuropeptide that regulates feeding in fruit flies, they decided to test whether they could exchange the two. Their success in doing so highlights the deep evolutionary origins of feeding regulation.

Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards      (via sciencedaily.com)     Original source 

Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease      (via sciencedaily.com)     Original source 

Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.

Coral skeletons influence reef recovery after bleaching      (via sciencedaily.com)     Original source 

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

Was plate tectonics occurring when life first formed on Earth?      (via sciencedaily.com)     Original source 

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.

Ocean warming intensifies viral outbreaks within corals      (via sciencedaily.com)     Original source 

A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.

Scientists discover hidden crab diversity among coral reefs      (via sciencedaily.com) 

The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.

Earth prefers to serve life in XXS and XXL sizes      (via sciencedaily.com) 

Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
