3:19 PM | What is Color and How Can It Help Kill Cancer Cells?
Spring is officially here and I don’t know about you, but I’m excited to welcome back COLOR: the bright rays of sunshine, the baby blue sky, the lively green grass, and of course, the plethora of vibrantly colored flowers.   But have you ever wondered what is color?  To understand the marvels of color and how […]

3:03 PM | Your Brain on Fiction
By: Lina Jamis, 1st year student in the Anatomy Graduate Program People love stories—we build social networks around them, we recount them to our friends and families at the end of our day, we whisper them in the dark to our…Read more ›

2:55 PM | No-response rejections from major university graduate programs?
I've heard anecdotal reports about major graduate programs accepting application fees and not sending any communications or rejections -- have you heard anything about this? (NB, it wasn't in chemistry, but it was a science/engineering field.)

2:00 PM | The perfect marriage of crystallography and mass spectrometry: PI3K
  Sorry for the cheesy title, but I’m getting married in a couple of weeks and it is all I can think about (oh, and science of course).  I have to admit that I chose a GREAT paper this time!: “Molecular determinants of PI3Kγ-mediated activation downstream of G-protein–coupled receptors” which was published last year in […]

2:00 PM | Art and Science: Two Parts of a Whole
By Michal Meyer Are art and science ying and yang, essential yet opposite parts of our world? We can trace the origins of material science to the first cave drawings made thousands of years ago. The artists who left these pictures likely began with trial and error attempts made with burned wood and colored dirt. Even then art and science were mingling, taking physical form through pigment. Art and science also meet in fascinating ways in the Dutch alchemical paintings that were so popular in […]

10:23 AM | Nanoparticle-delivered local anesthesia
A technique using anesthesia-containing nanoparticles - drawn to the targeted area of the body by magnets - could one day provide a useful alternative to nerve block for local anesthesia in patients, suggests an experimental study.

8:18 AM | Topological insulator - a novel optical and microwave-absorbing material
Recently, a new Dirac material - a lattice system where the excitations are described by relativistic Dirac or Weyl equations - namely a topological insulator (TI), entered researchers' sight. TIs possess a small band gap in their bulk state and a gapless metallic state at their edge/surface. A research group working on two-dimensional materials photonicshas now experimentally demonstrated for the first time that TI may be a novel microwave-absorbing material.

7:54 AM | Nanocrystalline cellulose modified into an efficient viral inhibitor
Researchers have succeeded in creating a surface on nano-sized cellulose crystals that imitates a biological structure. The surface adsorbs viruses and disables them. The results can prove useful in the development of antiviral ointments and surfaces, for instance.

5:27 AM | Still more corrections: An explanation?
I noticed that Fukuyama and Yokoshima have talked to C&E News about the rather large series of corrections that appeared recently. There appear to be 11 at the moment in publications stretching back over a number of years. A comment from Yokoshima is “We have told our students that the NMR spectra should not contain […]

6:28 PM | Nano shake-up: Routine handling can affect nanoscale drug carriers
A common assumption is that once a nanocarrier is created, it maintains its size and shape on the shelf as well as in the body. However, recent work has shown that routine procedures in handling and processing nanocarrier solutions can have a significant influence on the size and shape of these miniscule structures.

2:03 PM | Ketchup Rheology Video
I've discussed ketchup rheology a couple of times in the past (1, 2), but a new TedEd video really does a great job of visually showing the rheology and also getting into some of the details.Early in the project I had a few emails back and forth with George Zaidan, one of the creators. He's has a great talent for writing scripts, so much so that I have forever sworn off even attempting to ever write one. You can read his writing and easily imagine the finished product - that's quite a skill. […]

10:51 AM | Chicken and egg scenario
It's all a bit chicken and egg, getting experience I mean. As you move into your chosen career you are likely to come up with the words ' I'm sorry, you just missed out, the other candidate had a bit more experience' or something similar. In an ideal world you would have some experience before embarking on your new job, but how do you get experience without a job, and how do you get a job without experience? See what I mean? It's a chicken and egg scenario. As I talk to people, particularly […]

9:23 AM | Researchers achieve complete control over on/off switching of the movement of a nanomachine
Over the past few years, researchers have demonstrated that microtubules driven by kinesin make flexible, responsive and effective molecular shuttles for nanotransport applications. In order to fully control microtubules driven by kinesin it has to be possible to switch them on, switch them off, and regulate the speed and direction of their movements - achievements that until now researchers have't fully attained yet. Now, though, it has become possible, for the first time, to achieve complete […]
