Joy of Movement offers dance for all
Cambridge based Joy of Movement provides a wide range of classes including Feeling Good dance for toning the body and courses in ballet tap and belly dancing. Director Jill Greenburg says the center aims to remove competition and help people connect with music and their bodies. The studio opened in 1973 by Ken Estridge, drawing 800 sign ups at opening and about 3,000 last spring with students spanning college age to adults, and plans to partner with local employers for lunchtime exercise programs to boost productivity.

Motion sickness tied to ancient poison defense system
Oxford psychologist Michel Treisman proposes motion sickness evolved as an early warning against poisons. He argues nervous system toxins may disrupt balance inputs, triggering vomiting as a protective response. Infants and puppies show less susceptibility, supporting a defense-based theory.

Siberian Tunguska Explosion Likely Comet Event
Reports from Nature and a Tomsk University expedition suggest the 1908 Tunguska blast over the Stony Tunguska River valley was caused by a comet about five miles high, releasing about 12.5 million tons. New Scientist data support a comet, not a meteorite, scattered into tiny particles. Some earlier radiocarbon readings tied to 1909 may reflect neutron exposure.
