Pause in recent coral recovery on much of Great Barrier Reef      (via sciencedaily.com) 

In-water monitoring shows hard coral cover across the Great Barrier Reef remains at similar levels to that recorded in 2022, with small decreases in the Northern, Central and Southern regions. AIMS' Annual Summary Report on Coral Reef Condition for 2022/23 found that while some reefs continued to recover, their increased hard coral cover was offset by coral loss on other reefs. Most reefs underwent little change in coral cover.

Sun 'umbrella' tethered to asteroid might help mitigate climate change      (via sciencedaily.com)     Original source 

Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.

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.

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.

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.
