I saw a bunch of people yesterday tweeting approval of John Hawks’s complaint about academic timidity when it comes to blogging: The bottom line is: People need to decide if they want to be heard, or if they want to be validated. I have long been an associate editor at PLoS ONE, and once I…

New, more efficient drug formulations designed to treat illnesses through skin applications - thus avoiding serious side effects associated with oral drug-taking - have been developed by a student at the Hebrew University of Jerusalem. The method is based on utilizing skin-permeable proteins that are inserted into nano-structured gels.

The real challenge in the food arena is to produce functional food sustainably that is both nutritious and affordable, says Ioannis Zabetakis, Assistant Professor of Food Chemistry, at the University of Athens, Greece. This task is not an easy one. We need to combine good management practices, use resources effectively, make sensible use of water [...]More science scoops:Fats and food security, the lipid linkFunctionality against cardiovascular diseasesTaking the PNew SciScoop column on food

As previously noted, I spent most of last week at the 2013 DAMOP meeting, where I listened to a whole bunch of talks. At some point, I was listening to a talk, and said “I bet this guy hasn’t given a lot of these before.” What was the give-away? The fact that he almost never…

Mobile phones that bend, self-powered nanodevices, new and improved solar cell technology and windows that generate electricity are but a few of the potential products from the union of semiconductors and graphene.

Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate, findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft.

Aomically precise manufacturing (APM) can be understood through physics, engineering design principles, proof-of-concept examples, computational modeling, and parallels with familiar technologies. APM is a prospective production technology based on guiding the motion of reactive molecules to build progressively larger components and systems. Bottom-up atomic precision can enable production with unprecedented scope (in terms of product materials, components, systems, and performance), while […]

Fans of the network theory series might like to look at this paper: • John Baez, Quantum techniques for reaction networks. and I would certainly appreciate comments and corrections before I slap it onto the arXiv. This paper tackles a basic question we never got around to discussing: how the probabilistic description of a system […]

Yesterday I had the pleasure of visiting the Measurement Standards Lab at Lower Hutt. We were talking about making measurements of electrical impedance. In practice, if you want a decent measurement, it's rather less straightforward than whacking...

So, in physics graduate school, you have your quantum mechanics, and your EM, and your statistical mechanics, and classical mechanics, and so on, and all of this is very well and good. And then, if you're very, very lucky, there's machine shop class and it's awesome!!! Obstensibly, the class is to teach you to be a better communicator with machine shops, but you still get to learn how to use the tools! You actually get to learn how to build scientific instruments. It's […]
