Which countries have emitted the most carbon since 1850?
To get a sense of how ridiculous carbon pollution has become, going back in time gives some perspective.

The Federal Communications Commission approved a proposal for a controversial set of new net neutrality rules this morning that advocates say could undermine the very principals that they set out to support by introducing so-called “fast lanes” to the internet. The rules aren’t set in stone just yet, however: as the FCC has been reiterating for the past month, what it was voting to approve today was only a draft, and public comments received over the coming weeks will factor into what the final rules look like. The commission is even running a particularly long commenting period this time around given the outcry over and importance of the proposal.
That public comment period begins today and will run for 60 days, until July 27th, at which point a second phase of commenting will open up. That second phase will run for 57 days beyond that, until September 10th, and is meant to allow the public to reply to comments that the FCC received during the first phase. Traditionally, those interested in making a short comment would have to do so here, on proceeding number 14-28, and longer entries would have to be included as attachments through this larger form. But given the amount of interest the FCC is expecting, it’s also set up an email address, openinternet@ , where it’s accepting comments too in order to make the whole process a bit easier. Regardless of the method, all comments are made publicly. Comments on the proposal have technically been rolling in for months now, but the initial public comment period properly begins today.
Researchers find neurons responsible for tying together fearful events with environment
Researchers working at Columbia University have identified a neuron that serves to tie fearful events with the environment in which they occurred. In their paper published in the journal Science, the team explains how they isolated the special neuron and how its identification furthers the understanding of how memories are formed in the brain.
When an animal (or person) experiences something that truly frightens them, say by being shocked when touching a badly grounded appliance, they learn to fear not only the thing that shocked them (the appliance) but the environment in which the shock occurred (such as the kitchen). Such learning experiences are clearly an evolutionary development that aids in a species surviving—by avoiding such environments and appliances in the future, they will be more likely to survive. But there’s a little more to the story, prior research has shown that the brain also builds memories that tie the two parts of the experience together—memories specifically geared to causing a reaction when encountering both the environment and the actual thing that shocked them. Scientists have known for some time that an intermediate step must be involved in such memorycreation, but until, haven’t been able to isolate it. In this new effort, the researchers have found the specific neurons in the brain that appear to be responsible for tying such information together to form associated memories.
Suspecting that neurons in the hippocampus might be involved, the researchers focused on inhibitor cells known as intermeurons. To find out if they do indeed play a role, the researchers trained mice to fear a specific environment (a special box) by shocking them when they were put into it. Subsequent tests showed that the mice grew fearful of the environment—but when the intermeurons in the mouse brains were physically deactivated, the mice no longer feared the box. This shows, the researchers suggest, that intermeurons are essential for the formation of memories that are associated with an environment.
Isolating the particular neurons that play a key role in the creation of memories that are tied to both an event that occurred and its environment might perhaps be useful for helping treat people with disorders such as anxiety or even PTSD. If the neuronsresponsible for the creation of disturbing memories can be disabled or muted, then the person might find some relief from the emotional reactions that occur when exposed to triggers.
Payu Harris, Head of the Lakota Nation, on MazaCoin, a new crypto-currency that has been adopted by a confederation of seven Native American tribes as their national currency.
In preparation, the nation has mined some 25 million MazaCoins to be utilized as a national reserve of sorts. A further 25 million are on standby for a Tribal Trust – a collective which will issue grants to tribe members or support local businesses. A handful have already agreed to start using the coin.
The FBI has already allegedly contacted Harris to discuss the proposals to immerse themselves in the crypto-currency, apparently having reminded him that cryto-currencies are not considered legal tender in the US, currently. Harris has dismissed the warnings.
