2:59 AM | Standard operating procedures exist in our world!
On August 14, 2014, the state of New Hampshire (NH) issued a state of emergency resulting from a series of synthetic cannabinoid-related illnesses. No actual adverse effects were described in Governor Hassan’s press release, but the alleged product was identified as the bubblegum flavor of “Smacked!”. According to reports, starting on August 11, 2014, the product was responsible for adverse effects in at least 41 people across the state of NH. InfectiousChris over at the […]

7:13 PM | Scientists craft atomically seamless semiconductor junctions only three atoms thick
Researchers have demonstrated that two of these single-layer semiconductor materials can be connected in an atomically seamless fashion known as a heterojunction. This result could be the basis for next-generation flexible and transparent computing, better light-emitting diodes, or LEDs, and solar technologies.

7:12 PM | PSA for professors and other supervisors with access to social media
Just in case you didn't know, it's not helpful to call out your direct reports on social media, especially platforms that lend themselves to screen shots and anonymous image sharing sites.(Should a professor or other boss-type entities friend their direct reports on social media? No, says CJ.)

7:06 PM | August 2014 Chemical Activity Barometer slowing a bit, but still grows
From the American Chemistry Council: The Chemical Activity Barometer (CAB), a leading economic indicator created by the American Chemistry Council (ACC), continued to see moderated upward growth this month, with a 0.2 percent gain over July as measured on a three-month moving average (3MMA). This represented a deceleration from the 0.4 percent gain in July and an average gain of 0.5 percent for the first six months of 2014...  “Consistent with other recent economic reports, […]

3:18 PM | The Ebola outbreak would be so much worse without plastics
There are a lot of dangerous jobs in the Ebola hot zone right now, but the possible worse job would be that of handling the bodies of those that have just died. Despite the general recommendation to avoid touching people with the disease, these bodies do need to be handled in order to dispose of them without furthering the spread of the disease. And the only safe way to do that is by using plastics and polymeric materials to encase the corpse and protect the workers. A recent Buzzfeed article […]

2:16 PM | Hemp: Not Just for Rope and Granola
Hemp is back, man, and more energizing than ever. David Mitlin, then at the University of Alberta and now at Clarkson University, has developed a method for making supercapacitors out of hemp that is not only much cheaper than graphene (the cream of the crop as far as organic conductors go), but also outperformed standard devices by nearly 200%.

1:25 PM | What are Researchers Doing to Stop the Ebola Outbreak?
The latest Ebola outbreak is already considered to be the worst since the disease was first identified in 1976. In previous outbreaks, careful containment regulations have successfully stopped the spread of the virus, maintaining the number of infected to only a few hundred per year. This time however the virus is spreading in an uncontrollable [...]
