Controlling Brain Activity With Magnetic Nanoparticles

Slashdot - Fri, 13/03/2015 - 9:21pm
sciencehabit writes: Deep brain stimulation, which now involves surgically inserting electrodes several inches into a person's brain and connecting them to a power source outside the skull, can be an extremely effective treatment for disorders such as Parkinson's disease, obsessive compulsive disorder, and depression. The expensive, invasive procedure doesn't always work, however, and can be risky. Now, a study in mice (abstract) points to a less invasive way to massage neuronal activity, by injecting metal nanoparticles into the brain and controlling them with magnetic fields. The technique could eventually provide a wireless, nonsurgical alternative to traditional deep brain stimulation surgery, researchers say.

Kim Stanley Robinson Says Colonizing Mars Won't Be As Easy As He Thought

Slashdot - Fri, 13/03/2015 - 8:38pm
An anonymous reader sends this excerpt from io9: Kim Stanley Robinson's Mars trilogy filled us all with hope that we could terraform Mars in the 21st century, with its plausible description of terraforming processes. But now, in the face of what we've learned about Mars in the past 20 years, he no longer thinks it'll be that easy. Talking to SETI's Blog Picture Science podcast, Robinson explains that his ideas about terraforming Mars, back in the 1990s, were based on three assumptions that have been called into question or disproved: 1) Mars doesn't have any life on it at all. And now, it's looking more likely that there could be bacteria living beneath the surface. 2) There would be enough of the chemical compounds we need to survive. 3) There's nothing poisonous to us on the surface. In fact, the surface is covered with perchlorates, which are highly toxic to humans, and the original Viking mission did not detect these. "It's no longer a simple matter," Robinson says. "It's possible that we could occupy, inhabit and terraform Mars. But it's probably going to take a lot longer than I described in my books."
