New research highlights risks of selective adaptation in extreme coral habitats      (via sciencedaily.com)     Original source 

Resilient corals, often referred to as 'super corals', have recently been seen as potential saviours in the face of climate change and its detrimental effects on coral reefs. Now, a team of scientists is working to better understand these corals in order to develop strategies to protect fragile ecosystems such as the Great Barrier Reef.

Hubble sees evaporating planet getting the hiccups      (via sciencedaily.com) 

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

Listen to a star 'twinkle'      (via sciencedaily.com)     Original source 

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.

Webb snaps highly detailed infrared image of actively forming stars      (via sciencedaily.com)     Original source 

Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.

Astronomers reveal new features of galactic black holes      (via sciencedaily.com) 

An international team of scientists, including astrophysicists, report on a dedicated observational campaign on the Galactic microquasar dubbed GRS 1915+105. The team revealed features of a microquasar system that have never before been seen. Using the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers discovered a quasi-periodic oscillation (QPO) signal in the radio band for the first time from any microquasar systems.

Genetic study reveals that a captive-bred population could save endangered crocodile from extinction      (via sciencedaily.com)     Original source 

Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.
