8:13 AM | Manipulation of Anthrax to Deliver Cancer Drugs to Tumours
Cancer is acknowledged as one of the most dangerous biological diseases and there are many ongoing research studies to try and find suitable drugs to cure the uncontrollable cell replication. Cancer is caused when cells replicate unusually and rapidly to form tumours, this is because the cell does not undergo apoptosis (the normal programmed cell death) and these tumours need to be treated so

8:23 PM | Updated #chemnobel odds for tomorrow
So today's physics Nobel Prize was awarded to three physicists who worked on blue LEDs, devices that make light bulbs glow brighter and last longer than normal ones. It's a well-deserved recognition, really one for a physics-based invention rather than for a fundamental discovery (as an aside, it's worth noting how much the invention owes to the chemistry of gallium nitride semiconductors). The last time an invention was recognized was when the prize was given out for CCDs in 2009.However I […]

8:12 PM | Who was Gerry Mander?
Moving the political goalposts – Gerrymandering is the deliberate design of voting districts to achieve a specific outcome other than fair representation in a governmental election. It is named for US Governor Elbridge Gerry of Massachusetts, who signed the Massachusetts Senate Redistricting Bill of 1812 that included several “creatively” drawn districts designed to ensure his […]Who was Gerry Mander? is a post from the science blog of science journalist, photographer […]

6:40 PM | Chemical Warfare – The Chemistry of Nerve Agents (Part I)
Today’s graphic looks again at the darker side of chemistry, after the previous post on the various chemical agents used in World War 1. The present day spectre of chemical warfare is largely concerned with nerve agents, which come in two main groups; today’s post examines the G series of nerve gases, including sarin, which […]

3:57 PM | From Russia with love? Report on a new synthetic cannabinoid
Russia’s Health Ministry has recently reported on 25 synthetic cannabinoid-related deaths, along with more than 700 hospitalizations. The substance in question is simply described as MDMB N-Bz F. Average age of the hospitalizations is estimated at 24. According to this article, the substance has sent users “into vegetative state, provoking dementia and even respiratory arrest.” Other reports of this substance include a male who stabbed himself several times after smoking the […]

3:02 PM | The 'cyberwar' against cancer gets a boost from intelligent nanocarriers
Cancer possesses special traits for cooperative behavior and uses intricate communication to distribute tasks, share resources, and make decisions. New research now offers additional insight into the lethal interaction between cancer cells and the immune system's communications network.

2:54 PM | Researchers design 'molecular Pom Poms' from self-assembling peptides
Starting from a specific type of peptides (amino acid chains), researchers have developed a hierarchical system that, under appropriate conditions, self-assembles leading to spherical structures similar to the pom-poms used in some clothing.

1:50 PM | Nanotechnology could revolutionize treatment of eye conditions
Researchers developed novel nanoparticles that could attach to the cornea and resist the wash out effect for an extended period of time. If these nanoparticles are loaded with a drug, their longer attachment to the cornea will ensure more medicine penetrates the eye and improves drop treatment.

1:43 PM | Researchers discuss the future of organic photovoltaic devices
Organic photovoltaic devices (OPVs) have major potential as a principal source of clean electricity for the future. However, the large-scale introduction of OPVs onto the market is currently limited by their stability. The StableNextSol Action aims to create a highly interdisciplinary network of academic and industry researchers to study the degradation mechanisms occurring in state-of-the-art OPVs.

1:40 PM | A New Plastics-to-Oil Operation - In Syria?
I written in the past 1, 2 about "Plastics-to-Oil" (PTO), the process for anaerobic pyrolysis of plastics which ends up creating a sweet, crude oil. There are a few smallish operations here in the US but at this point in time, it does not play a critical role in our economy. And with gas prices continuing to fall (I saw $2.99/gallon yesterday for the first time in about 5 years!), that won't change soon.But is Syria, the story is different. There, all fuels are at a premium and so PTO suddenly […]

Until now, if you want to print a greeting card for a loved one, you can use colorful graphics, fancy typefaces or special paper to enhance it. But what if you could integrate paper-thin displays into the cards, which could be printed at home and which would be able to depict self-created symbols or even react to touch?

10:15 PM | I did a Nobel thing…
It’s difficult to make predictions, especially about the future – so said Niels Bohr (or maybe Yogi Berra, or Mark Twain or… boy, it’s hard to track down who *really* said something…). Anyway, @carmendrahl and @laurenkwolf from @cenmag were kind enough … Continue reading →

4:18 PM | Get rid of the mole?
From this week's C&EN and the Too Logical To Happen file:Regarding the ACS Comment “Check Your IQ on the SI”: In theory, we can dispense with the mole (C&EN, Aug. 4, page 32). The mole, molarity, and molality were adopted as convenient ways to express relative amounts and concentrations of substances when we didn’t know the actual mass of atoms and molecules—when the very existence of atoms and molecules was in dispute. Now we know, which has enabled us to […]

4:04 PM | This week's C&EN
Lots of interesting things in this week's C&EN:Enjoyed reading/learning about immune cell therapy in Lisa Jarvis' cover article. Those interested in the inside-baseball of journal editing and consecutive appearances in the literature will enjoy this Carmen Drahl article. Gosh, this Marc Reisch article about Chinese chemical manufacturers driving out competition in the artificial sweeteners market is interesting; wonder where the stuff that goes into Diet Cokes comes […]

2:30 PM | 55 applications later...
After countless alterations to my CV and a shameless outpouring of enthusiasm into numerous cover letters, I am finally about to start the next step of my career. In my search for the perfect career move I sent out 55 applications. Many of these were actually for industry positions that I thought, "well I can do that, it would be ok and is kind of my skill set", and so I was not too surprised when I didn't get the job. But I was always optimistic and therefore always disappointed. I really […]
