I would like to know if this statement is scientifically correct, or if it's hyperbole, or if it's basically correct but requires qualification: "Most of the atoms that formed your infant body at birth are now dispersed, as your present atoms will be again, if you have the good fortune to live a few more years on this oxygen-rich planetary home."

I'm a couple years off finishing a PhD that's been about half biochemistry and half electrophysiology at a top-ranked Australian university. The academic career path is definitely open to me - I've got a decent number of publications, heaps of teaching experience, blah blah blah - but I'm unsure that it's what I want to pursue.

Tomasetti and Vogelstein recently published an analysis that suggests the variation in the number of stem cell divisions leads to cancer incidence rates that are higher for tissues with relatively greater numbers of divisions. They recently posted a follow-up which attempts to address some of the counterarguments to their results. Acting on the premise that their work is correct or at least "in the right direction", are there labs or drug companies working on gene therapies that attempt to improve DNA polymerase fidelity (even in model organisms), as a means to one day perhaps reduce cancer incidence in higher-risk tissues? While it is easy through mutagenesis to worsen fidelity rates and increase cancer rates (as has been demo'ed in mice, say) can this aspect be engineered to be improved — that is, what biochemical aspects of (human) DNA polymerase have evolved to control its fidelity rate such that it might be possible to improve upon it?
My +1 is outfitting the molecular biology and biochemistry side of a physics lab. He would like to get books (electronic and/or paper) to fulfill two needs: 1. protocols and reference - for in lab use 2. history or textbook of molecular biology - to help familiarize physics people with the field. Looking for suggestions for solid books that are readable and have good figures. [more inside]
This seems like it ought to be a simple question but I'm not finding the answer myself. Someone here must already know. I would like to buy sheets of printable adhesive labels suitable for sticking on 1.5ml/2.0ml microcentrifuge tubes. Ideally I would like both dots for the caps and little rectangles for the sides. They don't need to be able to stand up to particularly tough conditions, except that they shouldn't run if they get wet. Also, they should be cheap as I am a grad student and would be buying them out of my own pocket. I am just sick of writing the same teeny tiny letters over and over and over again with an ultrafine Sharpie. Can somebody here point me to a product that I can buy that would suit my needs?

I'm looking for two books, one biology, one chemistry. They are related to GCSE, they say that on the front of the books, but I don't know if they're licensed. One has a green cover, one has a blue cover, but they both have pictures on the front. The good thing about these books is that they explain scientific concepts through diagrams in one-pagers, which are conveniently in both Chinese and English. Help me find these books? [more inside]
I want to write a science fiction story where somebody spends a few weeks or so living off a food that was intended for people colonising another planet, with odd effects. I'm not that scientifically knowledgeable and I want this to be grounded in facts. More details below. [more inside]
Looking for videos to create a youtube playlist to entertain a group of science-minded teenagers for about 30 min that are largely visual. Sound is fine but the bulk shouldn't be someone talking to the class like an instructor - visualizations are best - ideally they should look really, really cool. Class is engineering focused, but chemistry, robotics, wobbly bridges, comp-sci, biology, are all welcome. [more inside]
What is this thing my cat brought to my porch? http://i.imgur.com/cejZcGe.jpg It appears to be something between an animal fetus and organ. When I turned it over it looked the same on the other side. There were no visible eyes/mouth/features. It was larger than a quarter and there was no blood present. A possum visits regularly, and the area has many moles, birds, and raccoons.
I recently accepted a sales position within a company that sells laboratory equipment. (i.e. centrifuges, GC's, HPLC's, Thermal Cyclers, etc) I have no previous lab or science experience, so learning about a myriad of highly technical products/methods is a quite challenging. My main challenge comes from the fact that I need to engage in conversations with scientists, chemists, biologists on a daily basis. With no previous lab experience, I've been having a hard time talking to them on technical level. [more inside]

How common is human chimerism of the sort described in this Boing Boing post? What implications does the existence of chimerism have for DNA testing, especially with respect to the criminal justice system? Does it pose a practical limit on the usefulness of DNA evidence, or just a theoretical one? Has chimerism come up in any cases, or been considered as a problem in legal scholarship?

I'm a final year biochemistry undergrad, and through my internships / reading of papers / etc, I've become keenly aware that I'd like to be more conversant with computer science approaches to the field. The sheer volume of approaches and strategies in bioinformatics is a little overwhelming, though: where's a good place to start focusing my attention? I have strong maths skills, but my programming ability is limited to pecking out simple instruction sets in Python or Matlab, and my research work thus far has mostly been on isolating and characterising protein markers from serum / urine / etc.
What should I be doing to position myself for grad school? I'm a freshman biology undergrad and my long-term goal is to earn a doctorate and start a career in research, either private or academic.
