Frog species evolved rapidly in response to road salts      (via sciencedaily.com)     Original source 

When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.

Toward unification of turbulence framework -- weak-to-strong transition discovered in turbulence      (via sciencedaily.com)     Original source 

Astrophysicists have made a significant step toward solving the last puzzle in magnetohydrodynamic turbulence theory by observing the weak to strong transition in the space plasma turbulence surrounding Earth with newly developed multi-spacecraft analysis methods.

Giant galactic explosion exposes galaxy pollution in action      (via sciencedaily.com)     Original source 

Astronomers have produced the first high-resolution map of a massive explosion in a nearby galaxy, providing important clues on how the space between galaxies is polluted with chemical elements.

Lemur's lament: When one vulnerable species stalks another      (via sciencedaily.com)     Original source 

What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future      (via sciencedaily.com)     Original source 

The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.

No gamma rays seen coming from nearby supernova      (via sciencedaily.com)     Original source 

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

Seed ferns: Plants experimented with complex leaf vein networks 201 million years ago      (via sciencedaily.com)     Original source 

According to a research team led by palaeontologists, the net-like leaf veining typical for today's flowering plants developed much earlier than previously thought, but died out again several times. Using new methods, the fossilized plant Furcula granulifer was identified as such an early forerunner. The leaves of this seed fern species already exhibited the net-like veining in the late Triassic (around 201 million years ago).

Digging up new species of Australia and New Guinea's giant fossil kangaroos      (via sciencedaily.com)     Original source 

Palaeontologists have described three unusual new species of giant fossil kangaroo from Australia and New Guinea, finding them more diverse in shape, range and hopping method than previously thought. The three new species are of the extinct genus Protemnodon, which lived from around 5 million to 40,000 years ago -- with one about double the size of the largest red kangaroo living today.

Brightest gamma-ray burst of all time came from the collapse of a massive star      (via sciencedaily.com)     Original source 

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.

Oxidant pollutant ozone removes mating barriers between fly species      (via sciencedaily.com)     Original source 

Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
