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.

The structure of semi-crystalline polymers largely depends on how strongly their molecular chains are entangled. Following numerous experiments, researchers developed a new model to predict the microscopic structure of the materials as well as their properties. Polymers are long-chain molecules. Semi-crystalline polymers are a mixture of solid and liquid elements. They are often used in plastics and packaging materials.

Silver cluster-assembled materials (SCAMs) are emerging light-emitting materials with molecular designability and unique properties. However, due to their dissimilar structural architecture in different solvents, their widespread application remains limited. Now, researchers have developed two new SCAMs that exhibit excellent fluorescence and high sensitivity to Fe3+ ions in aqueous solutions, indicating their potential for environmental monitoring and assessment.

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.

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.
