  An enormously overgrown sheep that spent years in the wild and was saddled with so much wool that it could barely walk underwent a lifesaving "haircut" last month that removed more than 90 lbs. (41 kilograms) of fleece. Now, the animal affectionately known as Chris the Sheep has set a new Guinness World Records for having the most wool removed in a single shearing. Named by the wandering hiker who discovered him, the Merino sheep was then rescued by the Royal Society for the Prevention of C

• Pulsars Have Crunchy Crust, Supersmooth Interiors, Study Suggests

  06-10-2015 19:22
  
  Pulsars, the left-over remains of exploded stars, are considered some of the most accurate natural timekeepers in the universe, but even these excellent cosmic clocks aren't perfect. A new study suggests that pulsars occasionally exhibit a "glitch" in their timing because they are filled with a "superfluid" that can flow over any surface without friction. When massive stars grow old and die, they explode, sometimes leaving behind a neutron star — a small, incredibly dense nugget of collaps

  Takaaki Kajita and Arthur B. McDonald will share this year's Nobel Prize in physics for helping to reveal that subatomic particles called neutrinos can change from one type to another — a finding that meant these exotic particles have a teensy bit of mass. Neutrinos are the second-most abundant particles in the cosmos, constantly bombarding Earth. In their separate experiments, Kajita and McDonald each showed that neutrinos change between certain flavors — a process called neutr
