Make Pluto a planet again!
A scientific campaign has been launched to restore Pluto to planethood. Once the solar system’s ninth planet, tiny Pluto was demoted to “dwarf planet” status in 2006 after the International Astronomical Union redefined planets as round celestial bodies that circle the sun and have “cleared their neighborhoods”—that is, become the gravitationally dominant bodies in their orbit. Because Pluto is surrounded by icy debris, it lost its full planetary status. Now two scientists involved in NASA’s New Horizons mission to explore Pluto and the Kuiper Belt, Alan Stern and David Grinspoon, are pushing for Pluto to be let back into the club. The pair argues in a Washington Post op-ed that the IAU’s definition is deeply flawed. Earth could not have been classified as a planet for its first 500 million years, they note, because back then it, too, orbited among a field of debris. Stern and Grinspoon want the IAU to adopt a simpler definition of a planet: a round object in space that is smaller than a star. If they succeed, Pluto could once again be called a planet.
effect of eggs, researchers at the University of Sydney put 128 people with prediabetes or type 2 diabetes—a major risk factor for cardiovascular disease—on two different diets for a year. One group ate 12 eggs a week and the other ate two eggs or fewer a week. At the end of the study, the researchers found no adverse changes in cardiovascular risk factors in either group, including in blood pressure, weight, and cholesterol and blood-sugar levels, MedicalDaily.com reports. “Our research indicates people do not need to hold back from eating eggs,” study author Nick Fuller says, “if this is part of a healthy diet.”
