  Habitable Planet Reality Check: The Nearby Ross 128
Like many nearby stars, Ross 128 has been the target of exoplanet searches for decades. The most sensitive search results previously published were from an analysis of HARPS radial velocity (RV) measurements published in 2013 again with Xavier Bonfils (then with Observatoire de Genève) as the lead author. With only a half dozen measurements available at the time, the star’s RV seemed to vary on the order of a meter per second suggesting that the reflex motion of an exoplanet orbiting Ross 128 was being observed although it was impossible to claim a definitive exoplanet detection or characterize its properties with so little data. With this promising start, additional precision RV measurements were made by the HARPS team over the following years.

  The Jellyfish Dream Tonight
Researchers observe sleep-like behavior in jellyfish, a brainless organism : ====== (T)he revelations about jellyfish sleep are important, he said, because they show how basic sleep is. It appears to be a “conserved” behavior, one that arose relatively early in life’s history and has persisted for millions of years. If the behavior is conserved, then perhaps the biological mechanism is too. Understanding why jellyfish, with their simple nerve nets, need sleep could lead scientists to the function of sleep in humans. ======
