kidsneedscience: Happy Birthday OXYGEN.  I guess.  Words enter language and sometimes words disappear-often as quickly as they appeared.  In the transition from the ancient ideas of the ‘four elements’ of earth, air, fire and water, to the modern Periodic table, scientists struggled to understand basic chemical reactions such as oxidation.  In 1730 the word phlogiston entered the scientific vocabulary, meaning a hypothetical inflammatory […]

3:08 PM | Benefits: a favorite small company memory
So there we were, some years and some moves back, gathered for an all-hands meeting in the conference room with the new CEO and our local health insurance provider's representative. And he starts off with announcing some Great News! for the company: now, instead of employees paying 50% of their health insurance tab, the company would cover the entire cost except for $50.Great news!And then there's something mentioned about changes to the company's willingness to pay for health insurance for […]

11:21 AM | Tales of the abandoned glassware
Guest post by Heather Cassell I love working in the lab. I’m happiest when I’m pottering about among the bottles and the beakers getting on with my work. Most of my experience has been in multi-group labs of varying sizes; all have generally been good fun to work in, with lots of people to talk [...]

11:09 AM | Meet our guest bloggers – Heather Cassell
I’m Heather Cassell (née Stubley). I did a BSc in biochemistry and genetics at the University of Leeds, then I moved to the University of York where I did an MRes in biomolecular sciences followed by a PhD investigating enzyme activity in non-aqueous solvents. I am currently finishing my first postdoc position working as a [...]

11:05 AM | Detecting damaged DNA with solid-state nanopores
DNA is constantly being damaged in our cells by radiation and other random sources. One of the major forms of this damage is called depurination, or the selective loss of A and G bases from the double helix structure. In our cells, there is a system in place to fix depurination. It usually is quite successful at repairing the damage, but can sometimes make mistakes that result in mutations. As a result, depurination is directly linked to a host of diseases, including anemia and cancer. In new […]

8:41 AM | Anticancer Aspirin? Not so fast
The news was full of the discovery that taking some aspirin every day for ten years could somehow reduce your risk of getting cancer, particularly cancers of the gastrointestinal tract. The stomach bleeding side-effect (for some) and other as yet unknown side-effects aside, I was skeptical from the start, it just looked like a review […]Anticancer Aspirin?

2:43 PM | Smelly Sweat!
The hot sunny days are still around – maybe not for much longer! – and nobody is immune to a bodily function that can be particularly annoying if you’re trying to look your best: sweating. The big question is what are these unwanted wet patches, and what exactly makes them so smelly? Let’s find out [...]

2:42 PM | Coffee and Quinine
Historian Jon Grinspan wrote in the New York Times recently that during the American Civil War Southerners desperately roasted and brewed everything from potatoes to acorns in hope of simulating coffee. Even if coffee couldn’t cure disease, it may have been valued above any medicine by soldiers on both sides of the war. According to Grinspan, troops gushed about coffee in their diaries and letters, some going so far as to cite it as the reason they were still alive. Grinspan’s […]

1:56 PM | So you want to develop sustainable polymers, do you?
Here's a short description of the polymer production industry and what the challenges of bringing a new polymer into the world.6 plastics dominate: high- and low-density polyethylene, polypropylene, polystyrene, polyethylene terephthalate and polyvinyl chloride. They make up 76% of the market. These polymers are produced in factories that cost endless billions of dollars of capital and more are constantly being built around the world.Nobody is going to idle all that capacity without a fight.

7:40 AM | Crumpled graphene boosts performance of high-energy lithium storage materials
A three-dimensional crumpled graphene-encapsulated nickel sulfide electrode is reported as a superior high-energy lithium storage material. Compared with an electrode without crumpled graphene encapsulation, the optimized electrode yields significant improvements, especially in the cycling stability and rate capability. This enhanced performance is attributed to the 3D framework providing high continuous electron pathway and more free space for charge and mass transfer, and the stabilizing […]

11:52 PM | Synthetic Cannabinoid Illnesses in Indiana - August 2014
There are reports out of Fort Wayne, Indiana regarding six people hospitalized in a 12 hour period after using a synthetic cannabinoid product. While the overall number of people presenting is small, it was enough to garner some attention. No product names are given and no synthetic cannabinoids are named. Indiana has some strong laws around these compounds, including an exhaustive list of explicitly banned compounds and structural classes. The state also employs an analog clause and an […]
