Space reporter Miles O'Brien wrote a lovely farewell to the NASA's rover Spirit on the PBS NewsHour blog today, as NASA ceases attempts to reach the little robot that could.
It discovered silica deposits, carbonates, and evidence for hydrothermal systems and explosive volcanism. Billions of years ago, Spirit's site was a hot, violent place, with hot springs, steam vents, and volcanic explosions, and the little rover managed to suss that out.
But roving on Mars is not easy, and eventually Spirit found some sand that left it stranded. Since the JPL AAA card does not work on Mars, the rover had, in essence, dug its own grave. It was just a matter of time that the batteries would run down for lack of juice from the photovoltaic solar cells.
It is interesting, and somehow fitting, that Spirit was given its last rites on the 50th anniversary of John F. Kennedy's historic speech before a joint session of Congress. Kennedy said, "this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish."

Kratom (previously) is a widely used herb that has been very effective in treating opioid withdrawal and other chronic, hard-to-treat conditions — it also became very controversial this year because the DEA decided, without evidence, to class it as a dangerous drug, and then changed its mind (unprecedented!) after a mass-scale petition that included interventions […]
In a curious study, researchers at the University of California, Los Angeles showed that transcranial magnetic stimulation (TMS) — altering brain activity by zapping specific regions with magnetic pulses — can apparently increase people’s libido, at least briefly. Neuroscientist Nicole Prause and her colleagues targeted the left dorsolateral prefrontal cortex (at the left temple), a […]
