2:11 PM | A Response to the NY Times: "Choking the Oceans with Plastic"
The New York Times had an editorial on Monday by Captain Charles S. Moore, a long-time, outspoken advocate for raising awareness of plastic pollution in the ocean gyres. The editorial tells of the plastic pollution that he observed during his latest trip in the Pacific. While I do not doubt the veracity of his anecdotes, Moore uses a small subset of his observations to portray a wholly inaccurate image of what the pollution is like in the gyres in the Pacific and other oceans.Throughout the […]

1:29 PM | How is Potassium Permanganate Used to Treat Koi?
The effects of potassium permanganate (KMnO4) to treat koi’s external parasites have been known for over 200 years, but this product can be very dangerous to the fish if not used correctly. If you google it, you’ll find many accounts of very high doses applied to a pond, consequently killing all the fish. Potassium permanganate can [...]

8:11 AM | Researchers film protein quake for the first time
One of nature's mysteries is how plants survive impact by the huge amounts of energy contained in the sun's rays, while using this energy for photosynthesis. The hypothesis is that the light-absorbing proteins in the plant's blades quickly dissipate the energy throughout the entire protein molecule through so-called protein quakes. Researchers have now managed to successfully 'film' this process.

5:35 AM | I love our members
As the title suggests, I love the members of the Royal Society of Chemistry, our members, our community. I am on my last day in the fair city of Glasgow having done our first careers hub of the autumn. Whilst the focus is on careers consultations and actually getting to the places you live to support you we also have talks and networking, to help you find out more about the local people in your city/area. Last night for our Profiles in Chemistry talk we had David McMullan from Scottish Water. […]

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 […]

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 [...]
