4:19 PM | Warning Letter of the Week: bare hands!
I have a sense that FDA is stepping up its monitoring of pharmacies after the Massachusetts debacle. Here's a recent warning letter that's a bit disturbing: In addition, the investigators observed serious deficiencies in your practices for producing sterile drug products, which put patients at risk.  For example, our inspection found your facility was not physically designed and environmentally controlled to minimize airborne contamination, and the ISO 5 hood was located in an […]

12:52 PM | Guess I won't apply for this job
I am not looking for a job but that doesn't mean that I don't receive an endless stream of emails from recruiters on LinkedIn [*]. A recent one came with this beautiful snippet:"An Edisonian approach of trial & error, will not work for this role... this opportunity requires the ability to use theoretical modeling skills, fundamental / first principles knowledge, and deep understanding of polymer chemistry, in order to provide innovative solutions."This is scary. That an employer would have […]

11:07 AM | What is Hydrogen Peroxide?
Two men walk into a bar and both ask for a glass of water. Strangely, the second man dies after consuming his beverage! How to solve this apparently impossible conundrum? It’s not so strange if you know that, as the second man asked for H2O too, he was actually drinking quite a dangerous chemical: hydrogen [...]

9:54 AM | Twisted graphene chills out
When two sheets of graphene are stacked in a special way, it is possible to cool down the graphene with a laser instead of heating it up, researchers have shown.

9:06 AM | Toward optical chips with MoS2 light emitters
A promising light source for optoelectronic chips can be tuned to different frequencies.

9:00 AM | Recruiting bacteria to be technology innovation partners
For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of 'bad' biofilms around, researchers see biofilms as a robust new platform for designer nanomaterials that could clean up polluted rivers, manufacture pharmaceutical products, fabricate new textiles, and more.

8:52 AM | Scientists determine factors that give tubes their chiral angles
Researchers have come up with the seed of a simple formula that describes why nanotubes have chirality.
+
5:33 AM | New process allows fully additive roll-to-roll printing of flexible electrochromic devices
Electrochromic devices are some of the most attractive candidates for paper-like displays, so called electronic paper, which will be the next generation display. Researchers have now demonstrated solid state flexible polymer based electrochromic devices are fabricated continuously by stacking layers in one direction. This novel bottom-up approach with no need for a lamination step enables fully printed and 2D patterned organic electrochromics.

5:18 AM | 'Smart material' chin strap harvests energy from chewing
It is hoped that the device can generate electricity from eating, chewing and talking, and power a number of small-scale implantable or wearable electronic devices, such as hearing aids, cochlear implants, electronic hearing protectors and communication devices.

2:56 AM | Happy Birthday to the man who found life slipping away from his fingers
“In my quest for the secret of life I started my research in histology. Unsatisfied by the information that cellular morphology could give me about life, I turned to physiology. Finding physiology too complex, I took up pharmacology. Still finding the situation too complicated, I turned to bacteriology. But bacteria were even too complex, so I descended to the molecular level, studying chemistry and physical chemistry. After twenty years' work, I was led to conclude that to understand […]

6:32 PM | Oooops: NPR's non-research jobs link is dead
What I got when I clicked on NPR's link for Ph.D. workin "other fields."NPR's Richard Harris is doing a pretty great series on the difficulties of biomedical researchers. (The second link features an assistant professor-turned-grocer - yikes!) In today's segment, he goes over the travails of biomedical postdoctoral fellows, talking to 3 postdocs, all of which are trying to find tenure-track positions unsuccessfully. And then there's this little paragraph:There actually are jobs – in […]

6:09 PM | 11-065 28 Volt supply Check
The 28 V DC power supply in the PHI 11-065 ion gun control can become weak and cause symptoms such as low emission current. To test the supply, measure the voltage from the red wire to chassis ground. It should … Continue reading → The post 11-065 28 Volt supply Check appeared first on RBD TechSpot.

5:44 PM | A Brief Guide to the Twenty Common Amino Acids
The proteins that make up living organisms are huge molecules, but they’re composed of tinier building blocks, known as amino acids. There are over 500 amino acids found in nature, yet, of these, the human genetic code only directly codes for 20. Every protein in your body is made up of some linked combination of these amino […]

4:15 PM | For electronics beyond silicon, a new contender emerges
Using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude, a result the researchers are calling 'colossal'. In short, they have engineered this material to perform comparably with the best silicon switches.

2:41 PM | Au Revoir, Auf Wiedersehen, Adios..to The Real World Blog
Eric F. Brown, author of the blog The Rheol World" signed off for the last time yesterday. His blog will be missed as during it's heyday around 2010, it was pretty active, being both humorous and informative. Sadly the posting frequency has slacked off greatly as of late and yesterday the end was formally announced. I'm hoping Eric can restart the blog sometime in the future, so I will await that day patiently. My RSS feeder will be sure to alert me.Do stop by his blog once last time and be […]
