The United States doesn't currently have a plan for dealing with the problem of climate change. But President Obama is expected to bring it up in his State of the Union address tomorrow night.

Roberts of the Seattle-based environmental magazine Grist talks with David Hyde about his predictions on how the president will attempt to tackle climate change.
Both state and federal lawmakers have been debating over how to approach immigration reform. Immigrants themselves tend to favor paths to citizenship and educational opportunities for their children. But how do non-immigrants formulate their opinions on the subject? A recent academic study says that maybe our genes play a key role in shaping our political views. According to the research, people with a predisposition to social anxiety and fear are more likely to be critical of the unfamiliar and therefore more likely to support things like anti-immigration policy. David Hyde talks to lead author and political science professor Pete Hatemi to get the details.
State toxicologist Fiona Couper recently stated that violations for driving under the influence of marijuana have not gone up since the passage of Initiative-502. But marijuana legalization is still in its early stages and to be charged with a DUI the driver has to get caught with 5 nanograms per milliliter of active THC in their bloodstream. David Hyde talks with Dr. Marilyn Huestis from the National Institute on Drug Abuse, and tries to make sense of the science of marijuana intoxication.

But scientists couldn't figure out exactly what had caused this phenomenon. Of course, there were lots of theories.
