Published Biodegradable plastic from sugar cane also threatens the environment
(via sciencedaily.com)
Original source 
Plastic made from cane sugar also threatens the environment. Researchers from the University of Gothenburg have found that perch change their behavior when exposed to so-called bioplastic.
Published Supercomputer simulations provide a better picture of the Sun's magnetic field
(via sciencedaily.com)
Original source 
The new findings challenge the conventional understanding of solar dynamics and could improve predictions of solar weather in the future.
Published Honey bee colony aggression linked to gene regulatory networks
(via sciencedaily.com)
Original source 
In honey bees, the role a bee plays in the colony changes as they age. Younger bees perform duties inside the hive, such as nursing and wax building, while older bees transition to roles outside of the hive, either foraging for food (foragers) or defending the colony (soldiers). What determines whether older bees become foragers or soldiers is unknown, but a new studyexplores the genetic mechanisms underlying the collective behavior of colony defense, and how these mechanisms relate to the colony's overall aggression.
Published Forest birds with short, round wings more sensitive to habitat fragmentation
(via sciencedaily.com)
Original source 
Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.
Published Protecting large ocean areas doesn't curb fishing catches
(via sciencedaily.com)
Original source 
In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.
Published Saved from extinction, Southern California's Channel Island Foxes now face new threat to survival
(via sciencedaily.com)
Original source 
Starting in the 1990s, Island Fox populations began to dwindle due to an outbreak of canine distemper and an increase in attacks by golden eagles. Some islands saw their population drop to as low as 15 individuals, but conservation efforts by the Federal government restored numbers by 2017. A new study reveals a worrying decrease in genetic diversity within the species, signaling a new threat to the Channel Islands foxes' survival. The decrease in genetic diversity reduces the foxes' ability to adapt to future challenges, such as climate change and introduced pathogens, putting their survival at risk once again. Although the foxes have low genetic diversity, they possess diverse gut microbiomes that could help them cope with environmental changes.
Published Genetic change increased bird flu severity during U.S. spread
(via sciencedaily.com)
Original source 
Scientists found the virus strains that arrived in 2021 soon acquired genes from viruses in wild birds in North America. The resulting reassortant viruses have spread across the continent and caused more severe disease.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com)
Original source 
Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published How insects track odors by navigating microscale winds
(via sciencedaily.com)
Original source 
Insects use odor plumes -- which travel like smoke and form when the wind blows odor molecules from their source -- to track down sources such as flowers or pheromones. But wind tunnels are typically unable to replicate realistic outdoor wind conditions. Researchers decided to explore microscale wind conditions in various outdoor environments to better understand what flying insects might experience while tracking odor plumes.
Published One-third of galaxy's most common planets could be in habitable zone
(via sciencedaily.com)
Original source 
A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published The search for habitable planets expands
(via sciencedaily.com)
Original source 
Astronomers are suggesting a new way to expand the search for habitable planets that takes into account a zone not previously considered: the space between the star and what's called soot-line in planet-forming disks.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
(via sciencedaily.com)
Original source 
A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published How sweet it is: The fruit fly gut influences reproduction by 'tasting' fructose
(via sciencedaily.com)
Original source 
A research group has found that in fruit flies (Drosophila melanogaster), circulating fructose derived from dietary sugar is needed for enhanced egg production after mating. In this species, circulating fructose is required for an increase in germline stem cells, which divide into reproductive cells. This increase leads to enhanced post-mating egg production. These findings may help to determine whether fructose influences the reproduction of mammals, including humans.
Published New study provides novel insights into the cosmic evolution of amino acids
(via sciencedaily.com)
Original source 
All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic origin of this asymmetry. Based on the optical properties of amino acids found on the Murchison meteorite, they conducted physics-based simulations, revealing that the precursors to the biological amino acids may have determined the amino acid chirality during the early phase of galactic evolution.
Published Weevils, long-nosed beetles, are unsung heroes of pollination
(via sciencedaily.com)
Original source 
Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.
Published Deep sea surveys detect over five thousand new species in future mining hotspot
(via sciencedaily.com)
Original source 
There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science.
Published Move over, armadillos: There's a new bone-plated mammal in town
(via sciencedaily.com)
Original source 
Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.
Published Scientists from the Global South innovate to track ongoing amphibian pandemic
(via sciencedaily.com)
Original source 
Scientists have developed and validated an assay that could be used to diagnose Indian strains of the amphibian chytrid fungus that were not detected by previous tests. The novel assay also works for other better-known strains from other parts of the world, such as the one present in Panama.
Published A deep underground lab could hold key to habitability on Mars
(via sciencedaily.com)
Original source 
Tunnels deep underground in North Yorkshire are providing a unique opportunity to study how humans might be able to live and operate on the Moon or on Mars.
Published NASA's Hubble hunts for intermediate-sized black hole close to home
(via sciencedaily.com)
Original source 
Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
