7:03 PM | Your family tree just got a little bit more complicated....
Your family tree just got a little bit more complicated. Scientists recently confirmed that the DNA found in the fossil of a 45,000-year-old human contains traces of Neanderthal DNA. The fossilized bones were discovered near the Irtysh River in Siberia in 2008. Based on the amount of Neanderthal genetic material in the fossil, researchers believe that humans interbred with Neanderthals between 60,000 and 50,000 years ago. The difficulty of sequencing ancient DNA cannot be […]

11:48 AM | Friday Fun - Maitotoxin Watch
For those keeping tabs on K.C. Nicolaou's potential career capstone, the group has published another fragment (QRSTUVWXYZA') of the ladder polyether maitotoxin. By my count (and thanks to their handy graphic, below), they've now formed 30 of the 32 requisite rings, meaning we'll likely see a completed total synthesis in the next few years.*Top: MaitotoxinBottom: Previously disclosed fragmentsSource: Nicolaou et.al. | JACS 2014 ASAPWhen Nicolaou's group announced the move to Rice, one of my […]

10:24 AM | 5 Uses of Polyethylene Glycol
Polyethylene glycol – often shortened to PEG – is simply a polymer of ethylene oxide, with the structure H-(O-CH2-CH2)n-OH. It’s sometimes called polyoxyethylene (POE) or polyethylene oxide (PEO) according to its molecular weight: PEG refers to polymers with a molecular mass under 20,000 g/mol PEO refers to polymers with a molecular mass higher than 20,000 [...]

9:02 AM | Transitions between states of matter: It's more complicated, scientists find
A new study reveals the need to rethink one of science's building blocks and, with it, how some of the basic principles underlying the behavior of matter are taught in our classrooms. The researchers examined the way that a phase change, specifically the melting of a solid, occurs at a microscopic level and discovered that the transition is far more involved than earlier models had accounted for.

7:46 AM | Publication of the week, number 50, 7th November 2014
This week another new use for older compounds from the Baran labs. The ASAP discusses the use of quinone diazides in steroid synthesis. Now these things have been around for quite some time and are simply made by diazotisation of the corresponding aminophenol. So here we have a carbene source, what is the best way […]

10:43 PM | What have I learnt from post doc-ing?
I am no longer a postdoc. This both makes me ecstatic and sad. As a belated goodbye to academia post, I thought I would share my thoughts on my period as a postdoc. I learned a lot over the last 3 years or so and, looking back, am very glad I became a postdoc. I […]

8:16 PM | Ozone Nano-Bubble Water: Breakthrough for Chemists and Dentists
Ozone is typically associated with the ozone layer that surrounds the Earth and any articles about it are usually about the size of the hole in the ozone layer and how and what affects it every day. But that isn't what this article is about. This blog post is about how ozone can be bubbled into water to make nano-bubble water that is a powerful antiseptic agent that can be used to

7:37 PM | I don't think Impostor Syndrome ever goes away
This past week, Beth Haas posted on Impostor Syndrome and how she felt a little odd about being at her new workplace:I realized I was asking everyone around me for permission to be there, and that was undermining my confidence. I don't need anyone's permission to do my job. I'm the real deal, not an impostor. Like the spy movie cliché, people tend to assume you belong and you know where you're going. You just have to act like it. Do it long enough, and you might just fool […]

5:58 PM | Researchers culture norovirus
Norovirus is the leading cause of illness from contaminated food in the U.S.; its most infamous association is with outbreaks of food-borne disease on cruise ships. To date, researchers have been unable to culture the human version of the virus, which thwarts attempts to better understand its biology. Now, in a paper in the journal […]

4:21 PM | How do you disrecommend someone?
I have been extraordinarily remiss in not linking to C&EN's Employment Outlook section, but as readers may have sensed, it has been busy here this week. So, to rectify that, 3 links: Sophie Rovner's broad economic outlook is quite interesting, especially the focus on Paul Hodges' thoughts. It's worth a look, especially the ending paragraphs where they focus on the unemployment amongst East Coast pharma scientists versus the need for petrochemical workers in the Gulf region. Susan […]

The standard technique, using a top and a bottom gate, can lead to damaging of the graphene layer. This is avoided in the new method, which also offers linear I-V characteristics at low gate voltage. The two-top-gate structure is expected to be a practical route to a room-temperature terahertz source.

9:32 AM | How to make mobile batteries last longer by controlling energy flows at nano-level
Electronic devices waste a lot of energy by producing useless heat. This is one of the main reasons our mobiles use up battery power so quickly. Researchers have made a leap forward in understanding how this happens and how this waste could be reduced by controlling energy flows at a molecular level.
