3:53 PM | Finding new targets for attack on the bacterium that causes gonorrhea
April is Sexually Transmitted Disease Awareness Month and a good time to discuss Neisseria gonorrhoeae, the bacterium that causes gonorrhea. There aren’t any preventative vaccines for gonorrhea, and the bacterium is growing increasingly resistant to the antibiotics available to treat it. In a paper recently published in the journal Molecular & Cellular Proteomics, researchers describe […]

2:12 PM | Those Rich Petroleum Engineers
The Wall Street Journal yesterday had a poorly written opinion piece that was a mix of odds and ends that never really seemed to find its stride. The overall message is something of the following: petroleum engineering jobs are paying extremely well ($97,000 starting) but most schools are doing research on alternative energies and are brainwashing students not to go into petroleum engineering. Or since many schools don't offer that major, the students are also being guided away from what the […]

1:07 PM | PressPac: Toward a faster, more accurate way to diagnose stroke
Here’s an item from this week’s PressPac that we thought you’d enjoy. The PressPac features summaries of articles appearing in our peer-reviewed journals and Chemical & Engineering News. To get the entire PressPac in your inbox, email us at newsroom@acs.org.When someone suffers from a stroke, a silent countdown begins. A fast diagnosis and treatment can mean the difference between life and death. So scientists are working on a new blood test that one day could rapidly […]

12:30 PM | Chemical safety tidbits and papers, from OPRD
A tweet from Chemjobber that Organic Process Research & Development editor Trevor Laird is retiring at the end of the year made me realize that I forgot to highlight OPRD’s annual “Safety of Chemical Processes” section at the end of last year. Making up for the omission: Laird’s editorial: “There is a long way to […]

11:36 AM | A novel approach to designing drug-loaded nanoconstructs
Nanomaterials for nanomedicine and biological applications are often two-component structures - referred to as 'nanoconstructs' -consisting of a 'hard' nanoparticle core and a 'soft' shell of biomolecular ligands. Researchers have now demonstrated a nanoconstruct with enhanced in vitro efficacy. This highly loaded nanoconstruct was taken up by pancreatic cancer cells and fibrosarcoma cells at fast rates. The team found that the increased loading of Apt on AuNS also resulted in an enhanced in […]

7:30 AM | Scientist develop novel ultra-fast electrical circuits using light-generated tunneling currents
Scientists in Singapore have successfully designed and fabricated electrical circuits that can operate at hundreds of terahertz frequencies, which is tens of thousands times faster than today's state-of-the-art microprocessors. This scientific breakthrough has the potential to revolutionise high-speed electronics, nanoscale opto-electronics and nonlinear optics.

7:04 PM | Scientific Lessons from Bread Baking
Every day chemists enter their laboratories, intent on making or studying something. For me, my daily task is to think about nanoparticles. At the end of the day the thinking process is no different than a chef working in the kitchen. Small changes in your recipe can make a huge difference. The ingredients, types, amounts, […]

6:55 PM | Weird thought for the day
There's this trope that Big Pharma doesn't develop "cures" because it will ruin the market or there's not enough incentive to do so (i.e. if they can't sell lots of pills, the market won't be big enough. Here's a good example of that thinking.)So here's Gilead's Sovaldi, which is as close to "a cure" of Hepatitis C as we've seen in a while; it sure is expensive, running about $84,000 for an entire 12-week course. Isn't this proof positive that Big Pharma will work on cures, and if it finds one, […]

5:35 PM | Expanding particles to engineer defects
Materials scientists have long known that introducing defects into three-dimensional materials can improve their mechanical and electronic properties. Now a new study finds how defects affect two-dimensional crystalline structures, and the results hold information for designing new materials.

After installing a Linux Mint operating system (OS) as a “dual boot” setup alongside Windows 8 (not as bad as I’d heard!), I was hoping I’d be able to use some of the software I have student licenses for without having to restart each time. The open source LibreOffice just isn’t as smooth as Office 2013 packages, Office365 was made for the lightest of users and more than anything I’m comfortable as I was in the Office setup, with university supported […]

2:00 PM | The story of the phospholipase A superfamily
  The phospholipase A2 superfamily is a group of enzymes that cleave fatty acid groups from glycerol, in particular acyl groups at the sn-2 position. They contribute to numerous metabolic processes and diseases, including Alzheimer, epilepsy and multiple sclerosis; making this group of proteins very attractive to study. This superfamily includes groups such as secreted, […]

1:03 PM | The System Actually Works
Once people start distrusting the government, it is difficult to get them to reconsider, but this might: PlasticsNews is reporting that the Environmental Portection Agency (EPA) has told a New Jersey company to stop selling food containers with nanoparticles of silver in it.The company had not registered the pesticide with the EPA as they were required to. "Part of the registration process is qualifying that a product does not put human health at risk when used as it is intended...".It's pretty […]
