One thing system biologists want is to have by and large absolute protein concentrations or copy numbers per cells available cheaply for their models leveraging all sorts of omics data. Looks like such results can now be easily delivered based on a study published on the 15th of September by the Mann lab in Molecular & Cellular… Continue reading Changing the game: absolute protein quantification by relating histone mass spec signals to DNA amounts and cell numbers
1. DNA methylation age of human tissues and cell types by Steve Horvath: This is the type of relevant data mining study most bioinformaticians are dreaming of: you pull together a large body of publicly available datasets (CpG methylation) that are not too heterogeneous (Infinium type II assay on Illumina 27K or Illumina 450K array platform), derive robust… Continue reading Three links in Aging, Regenerative Medicine & Healthy Lifespan Extension: 17 December 2013
1. Is aging linear or does it follow a step function? A good & simple question on Quora that surprised even Aubrey de Grey. If you are a bioinformatician out there – looking for a new pet project – go pull together some data & try to plot it! Let me know if you have something.… Continue reading Three links in Aging, Regenerative Medicine & Healthy Lifespan Extension: 8 December 2013
The LavaAmp is a portable PCR thermocycler that has the potential to become the default garage biology (home biology, bioDIY, DIYbio) tool once it hits the market.

Nature’s Journal Club column is usually a good & always a short read providing exciting angles on scientific topics/papers from good researchers. Recently ‘neuroscientist’ Dave Featherstone argued for a broader approach to brain mapping by not restricting it only to the connectome between neurons. Neurons are making up less than 10% of the human brain… Continue reading Mapping neurons without glial cells ~ SNP genotyping w/o whole sequencing?
Surprise email from Conor McKechnie, GE Healthcare proving the aesthetics of science and the value of blogging: A while (!) back you posted an inspiring piece linking to Harvard’s BioVisions inner life of the cell – it was 2006…It got me thinking that we could do something similarly inspiring with actual cellular images entered into… Continue reading Bright cells, big city: Cellular images hit Broadway

Finally Chris over at Ouroboros came up with the idea and the quick implementation of Hourglass, a blog carnival devoted to the biology of aging/biogerontology. For some reason I am not an explicit supporter of blog carnivals – many of my posts were chosen by carnival editors but I never hosted one -, but Hourglass… Continue reading Hourglass, a blog carnival devoted to the biology of aging
The concept of decellularizing complex organs in cadavers and reseeding the remaining matrix structure with differentiated, stem or progenitor cells, growing in a bioreactor and transplanting back to the organism could turn out to be a real technological shortcut in the field of tissue engineering. It is not a brand new story on the web,… Continue reading The decellularized matrix hack: skipping many steps in tissue engineering
This is how my Macbook saw Aubrey de Grey’s talk exactly 1 week ago on the AGING preconference at UCLA.

“I feel like I am talking to an empty room. Why do I feel like I am talking to an empty room?” starts Michael Marron his Google Tech Talk on NIH and the computational infrastructure for biomedical research rather unfortunately. (I remember that room.)
Desktop background images are important parts of people’s everyday lives in terms of unintended staring time. Usually they are picked up for the eyes (sg spectacular & cool and/or sexy) and hearts (family members), but why not use them for information uptake and learning? So I’d like to ask: What’s your current science related desktop… Continue reading What’s your current science related desktop image?
Nature Biotechnology is the (peer review) journal for me: it’s geeky, fresh and it takes into account more than just one point-of-view, that of the scientist-academist’s: technology & business are hand in hands also. (Recommending Nat Biotech makes a niche sense here while recommending Nature, which is actually the only science journal I’m reading issue… Continue reading Puzzle: Which Wired article is cited in Nature Biotechnology?
David Secko writes: “Today, it is thought that one third of the proteins present in a typical mammalian cell are covalently bound to phosphate (i.e. they are phosphorylated at one time or another)” Well I haven’t checked what kind of measurement the above 1/3 estimation is based on but if true it is no wonder… Continue reading How overrated is phosphorylation? – an opinion
The 2006 Nature Insight: Stem Cells edited by Nature Report Stem Cells editor Natalie DeWitt is still a basic reading for me. The newest Nature is accompanied by a similar supplement called Nature Insight: Regenerative Medicine
It seems that my favorite ever unconference, the SciFoo Camp will be aroundunconferenced by a BioBarCamp this year. The whole idea of the BioBarCamp is based upon the SciFoo Camp, so it is by no means a competitive but a complimentary event. From the BarCamp wiki: “The BioBarCamp is an idea (fed by the tweets… Continue reading BioBarCamp in the Valley before the SciFoo Camp!
In order to have the slightest change to design a robust, systemic life extension technology, we need to accumulate every systemic macromolecular, cellular, tissue- and organ level data of the normal, physiological human body, connect the trillions of nodes with scalable software algorithms and suck out the draft of the proper sequence of consecutive treatment/regeneration… Continue reading Human proteome project: 21000 genes/1 protein, 10 years, $1 billion?
