Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study, published in The Journal of Physiology, shows that the pupil is smallest during inhalation and largest during... Continue Reading →
Rima Hyginus is a spectacular fissure, some 220 kilometers long, found near the center of the lunar near side. Easy to spot in telescopic views of the Moon, it stretches top left to bottom right across this lunar closeup. The image was made... Continue Reading →
Breast cancer incidence trends in U.S. women under 40 vary by geography and supports incorporating location information with established risk factors into risk prediction, improving the ability to identify groups of younger women at higher risk for early-onset breast cancer,... Continue Reading →
Enormous elliptical galaxy Messier 87 is about 50 million light-years away. Also known as NGC 4486, the giant galaxy holds trillions of stars compared to the mere billions of stars in our large spiral Milky Way. M87 reigns as the large central... Continue Reading →
How do stars and planets form? New clues have been found in the protoplanetary system Herbig-Haro 30 by the James Webb Space Telescope in concert with Hubble and the Earth-bound ALMA. The observations show, among other things, that large dust grains are more concentrated into a central disk where they... Continue Reading →

Scientists have developed new light-sensitive chemicals that can radically improve the treatment of aggressive cancers with minimal side effects. In mouse tests, the new therapy completely eradicated metastatic breast cancer tumors. The novel chemicals, called cyanine-carborane salts, and their role... Continue Reading →
