The B-factories have successfully exploited the unique advantages of the γ(4S) resonance to study many aspects of the Bd and Bu mesons. The γ(10860) resonance, also known as γ(5S), is above mass threshold for the Bs and shares many of the same advantages. The Belle experiment has collected more than 120 fb−1 at the γ(5S), corresponding to 7.9 million Bs events. First results from these data are presented, including the first observation of a baryonic decay of Bs, a novel measurement of sin2φ1, and observation of hb(1P), hb(2P), and two charged bottomonium-like states.
