In the early 2000s, a new set of data revised the chemical abundances at the surface of the sun, contradicting the values predicted by the standard models used by astrophysicists. Often challenged, these new abundances made it through several new analyses. As they seemed to prove correct, it was thus up to the solar models to adapt, especially since they serve as a reference for the study of stars in general...

Model of Lieb’s ‘minimal’ ferrimagnetism with Kondo effect using a ‘T’ of quantum dots. Dr. Nishikawa at Osaka Metropolitan University focused on the Kondo effect on minimal ferrimagnetism and attempted to elucidate it theoretically. As a result, they found that the Kondo effect occurred via multiple “quantum entangled states” depending on temperature and other factors. They also found that the Kondo effect suppressed electrical conductivity through minimal ferrimagnetism, when usually it is amplified in many other cases.

Most people are not aware of magnetic forces in their everyday lives, but continuously rely on them in electric motors, hard drives, and electric sensors...

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations from the Gemini North telescope, the NASA Infrared Telescope Facility, and the Hubble Space Telescope, researchers have developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet’s stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

Neptune and Uranus have much in common — they have similar masses, sizes, and atmospheric compositions — yet their appearances are notably different. At visible wavelengths Neptune has a distinctly bluer color whereas Uranus is a pale shade of cyan...

Researchers have discovered a mechanism linking breast cancer and diabetes, each of which promotes development and growth of the other. Breast cancer and type 2 diabetes would seem to be distinctly different diseases, with commonality only in their commonality. Breast cancer is the second most diagnosed malignancy after some types of skin cancer; approximately 1 in eight U.S. women will develop invasive breast cancer over the course of their lifetime. More than 10 percent of the U.S...
