1:45 PM | Nanospheres cooled with light to explore the limits of quantum physics
Scientists have eveloped a new technology which could one day create quantum phenomena in objects far larger than any achieved so far. The team successfully suspended glass particles 400 nanometres across in a vacuum using an electric field, then used lasers to cool them to within a few degrees of absolute zero.

11:55 AM | 'Smart bandage' detects bed sores before they are visible to doctors
Engineers are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new 'smart bandage' that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.

10:11 AM | New cheap and efficient electrode for splitting water
Scientists have developed a highly efficient oxygen-producing electrode for splitting water that has the potential to be scaled up for industrial production of the clean energy fuel, hydrogen. The new technology is based on an inexpensive, specially coated foam material that lets the bubbles of oxygen escape quickly.

9:14 AM | What is a Demineralisation Plant?
Most commonly, a demineralisation plant is composed by two pressure vessels with ion exchange resins. Depending on the type of impurities present and the intended use for water, various types for anion and cation resins can be used. This includes enhanced capacity, purafine; potable clear gel and gel polystyrene resins; as well as resins to [...]

8:00 AM | "Sam": "Very happy having left"
This story on leaving graduate school in chemistry is from "Sam"'; it has been redacted for privacy. 1. Why did you leave? So a little background first.  I graduated from [small prestigious college] in Chemistry with a strong desire to go into theory.  I was awarded a [redacted] Fellowship to study for a year in [European country X] in [redacted], and I deferred my admission to [University of West Coast].  While in [European country X], I applied for and was selected […]

7:00 AM | "QH": "I basically got fired."
This story is from QH; their story has been redacted for privacy and clarity by CJ:[Recently] I left grad school with my M.S. after [3+] years of trying to work toward my doctorate. Things got progressively worse over time and I kept telling myself "this is bottom. now I'll bounce back." but I never did.When I started grad school, I had already begun a successful research career as an undergraduate. When weighed against having to fight to get an entry-level job with medical benefits, versus the […]

12:31 AM | A hiring manager from pharma speaks about what they look for in new Ph.D.s
From a recent ItP thread, "tt" speaks (emphases mine): As a frequent reader/fan of this blog, I don't find it be all doom and gloom, rather it's a fairly realistic take on the state of the industry. I'm a hiring manager at a big pharma and can say that the industry is definitely changed as far as career stability is concerned. People who are adaptable and just plain good scientists tend to land well regardless of changes to an organization. For a fresh graduate, the forecast is just […]

11:51 PM | Acylboronates Enter the Mix?
Just a few days removed from the great Synthesis Machine debate of '15, a new paper has appeared that prompts me to wonder: might other protected boronates work in this chemistry?The Bode group, now at ETH-Zurich, discloses in JACS ASAPs some intriguing bifunctional acylboronates. Much like their MIDA boronate cousins, these, too, are stabilized by an N,O-chelating ligand, demonstrate a shelf-life of several months, and are easily prepared in one step from their […]

8:55 PM | Molecular ruler sets bacterial needle length
A step in understanding how microbes infect target cells. The findings have potential long-term applications for developing new antibiotics against salmonella and certain other disease-causing bacteria, for designing bacteria that could inject cancer cells with chemotherapy drugs, and for helping people how to design machines at the nanoscopic or molecular scale.

8:47 PM | Spherical nucleic acids set stage for new paradigm in nanomedicine drug development
Researchers have shown that spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. The initial treatment triggers a cell-specific immune response all over the body.

8:33 PM | «Quand trop, c’est trop!»
Les Manchettes scientifiques d’Ariel Fenster Imaginez qu'une université réputée propose de mettre en œuvre une étude pour déterminer «une fois pour toutes» si la terre tourne autour du soleil. Ne penseriez-vous pas que la question a déjà été réglée depuis longtemps et que c'est un gaspillage de […]

7:27 PM | Ambit.js: JavaScript client library for the eNanoMapper API technical preview
eNanoMapper is passed its first year, and an interesting year it has been! I enjoyed the collaboration with all partners very much and also the Open character of it. Just check our GitHub repository or our Jenkins build server.Just this month, the NanoWiki data on Figshare was released and I just got around to uploading ambit.js to GitHub. This library is something in development, and should too be considered a technical preview. This JavaScript client library, inspired by Ian Dunlop's […]

6:26 PM | L'Oreal holding a "Live Day" on March 26
An interesting idea from L'Oreal:If you are a scientist, passionate about making breakthrough innovations and with a desire to see your science transformed into products then join us on 26th March for the Live Day. We invite you to meet our experts and to find out more about the research that is carried out in our laboratories....I feel that L'Oreal is doing a pretty strong push for chemists in R&D, dunno if that's actually true.

4:05 PM | Antibiotic nanoparticles attack respiratory infection
Researchers have shown that the use of nanoparticles to carry antibiotics across biological barriers can be effective in treating lung infections. Doing so allows better delivery of the drug to the site of infection, and hence prevents the development of antibiotic resistance which may be caused by too large and continued doses of antibiotic.

2:47 PM | "Other than that, Mrs. Lincoln, how was the play?"
From former Pfizer R&D president John LaMattina, a focus on the "silver lining":...Clearly, the consolidation of the biopharmaceutical industry has not been good for new drug discovery and development. The reduction in R&D jobs, the time lost due to organizational redesigns, and the personal toll incurred by family dislocations or the need to find a new job have been terrible. However, in talking to people, particularly those who have found new opportunities, they have found their new […]
