7:32 PM | Stories wanted: "I Quit Graduate School in Chemistry"
At the end of Vinylogous' recent excellent post on mental health and graduate school in chemistry, he posited questions that people considering leaving graduate school should consider: There's a pervasive thought--"I've already put in 2 years, so it would be a waste of time to quit now." (Or however many years). But time already invested is a sunk cost. It doesn't matter how much time you've put in if you're not going to get anything out of the degree. Only three factors should matter when […]

3:57 PM | Glassdoor Review of the Week: Moderna Therapeutics
Speaking of Moderna, I am reminded that a couple weeks ago, someone at In the Pipeline posted a pretty awesome-not-awesome Glassdoor review of them (the review was written a year ago): Moderna takes advantage of all employees below the executive level- overworked and grossly underpaid, they feel as though they can get away with this type of behavior because of rival companies recently closing their doors. When the bubble bursts, the executives will have handsome rewards while the little […]

A few of the positions posted on C&EN Jobs this past week:Rocky Hill, CT: Henkel is looking for a Ph.D. synthetic polymer chemist; looks to be adhesive-related? Oak Ridge, TN: Interesting ad for a Ph.D. physical chemist to work on "helium ion spectroscopy." Sounds fancy.Cambridge, MA: Moderna Therapeutics (recipient of just a little money recently) is hiring an B.S./M.S. bioorganic chemist.Athens, GA: This ad for a scientist by Argent Diagnostics is a little bit strange and I can't quite […]

2:54 PM | Mimicking Nature’s Nanotechnology: From a butterfly wing to anti-counterfeit technologies
Have you ever wondered where the inspiration behind new technologies comes from? We don’t have to go too far to find out; it is enough to just look out the window! Look deep into nature, and then you will understand everything better. -Albert Einstein Yes, nature is out there, standing as a giant laboratory of […]

1:18 PM | An electron takes 40 attoseconds to pass through a single layer of atoms
An international team of researchers has measured how fast an electron races through the atomic layers of a crystal lattice. The physicists used an extremely short laser pulse to time the speed: According to their measurements, the electron needs 40 attoseconds to pass through one layer of magnesium atoms.

1:12 PM | New nanotechnology image contest hosted by the NNI
The goal is to envision where your research is headed and explain how 'seeing' at the nanoscale is important to reaching that vision. This contest is for students conducting nanotechnology research in the United States and U.S. territories.

1:06 PM | Wearable nanowire sensor clears path to long-term EKG, EMG monitoring
Researchers have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.

10:53 AM | Atoms can be in two places at the same time
According to the predictions of quantum mechanics, microscopic objects can take different paths at the same time. The world of macroscopic objects follows other rules: objects always moves in a definite direction. But is this always correct? Physicists have constructed an experiment designed to possibly falsify this thesis. Their first experiment shows that Caesium atoms can indeed take two paths at the same time.

9:45 PM | About the Benefits of Lemon Water that You may/may not Have Heard Of
When we think of lemons, or citrus fruits in general we think of vitamin C. In fact lemons are packed with more than just vitamin C; they are crammed with vitamin C, B-complex vitamins, calcium, iron, magnesium, potassium, and fibre. I have heard a lot about lemon water and how it’s good for you and great for your digestion. Obviously I wanted to research and find out more about lemon water. Little did I know just how many benefits there are!Preparing Lemon WaterBecause lemon juice […]
