Richard Feynman’s 1959 lecture “There’s plenty of room at the bottom” envisioned atomic pick and place to build complex nanoscale machines. The lecture is often considered the conceptual birth of nanotechnology. I am sure this is not the fi

Amazing that this can be achieved at such a low cost. The DVD optical pickup is truly a marvel of engineering, incorporating fairly complicated optics into such a small space. The focusing lens additionally has a electromagnetically contr

what about computational methods? i have always wondered how stacking many short exposures without tracking compares to deconvolution of a single long exposure. it seems that there is software able to do this by taking into account both mot

One important distinction is to understand that VA ECMO is more often used as mechanical circulatory support in cases of severe heart failure leading to cardiogenic shock. Used alone or in conjunction with other mechanical devices (balloon

Was the phosphorescent dye inhaled? What was the physical process responsible for the phase lag? Would love to read more about your device if you ever published your results!

I really enjoy using Julia too but I have also been disappointed with how the updates have played out. Just a few weeks ago I rolled back my installation from v1.2 to the LTS version because of silly errors in the plotting package not allow

True iodine deficiency is quite rare in the west as many table salts are fortified with iodine. It is extremely uncommon to see people with Goiter in the US. The same goes for thiamine/B1 deficiency which used to cause cardiovascular a

Building on your comment, I think that while it does help to have high quality cameras and objective lenses, it is always worthwhile to push the limits of how cheap we can go. There have been many nicely done papers in this vein recently, s

That is indeed an extreme example, given how matter of factly they teach transposons in molecular bio these days. When we couldn't get a paper published, my old PI would always joke, "There's always BBRC!", referring to

The hypothesis for many prion diseases is that of "seeding" whereby a small number (or maybe even a single) prion protein acts as a template to induce misfolding of other proteins with similar sequence but native folds [1,2]. Thi
