Most recent edition was published in 2012. It's extensively updated between editions, so very much worth reading if you are seriously interested in neuroscience.

This is overly judgmental. Accidental pregnancies happen (even with contraceptive use), and can often not be detected until several weeks have passed. Even if alcohol consumption is stopped immediately, fetal alcohol syndrome spectrum disor

It would be remiss to not mention the well-curated list by Gerard 't Hooft [1999 Nobel Laureate in Physics]. A lot of books on the list, but also a lot of links to freely available lecture notes or online books as well. http:/&#x

You might be interested in the normal physiology of cerebrospinal fluid [0] and the disease hydrocephalus [1] that occurs when there is a blockage in the normal flow path. As a treatment for hydrocephalus, bypass shunts (made of tubing) are

As I understand it (from friends in med school), the grades in the pre-clinical classes are important as they affect the Dean's letter, the primary letter of recommendation for residency applications. However, the grades from the time

An advantage of the silicon photonics (over other on-chip optical technologies) is that we can leverage a lot of the experience that we have with silicon to fabricate these devices. There are still large technological challenges, since we o

Seconding this recommendation -- this book was a really fun (and fast!) read and was really eye-opening about how real memory tricks work and started to get me thinking about the utility of having vast amounts of information memorized.

It has the potential to be inefficient if they choose the wrong group of scientific advisors. But, for most of these initiatives, they're very careful to choose smart people to actually lead the details of the project and figure out ho

I would expect so. Alcohol can cause inflammation, triggering various parts of the immune system to kick in. This could result in the release of free radicals from these immune cells, which promotes DNA mutations.

I recommend Connections or The Day the Universe Changed (out of print, I think?), both by James Burke. These aren't comprehensive histories of science, but they show how science, technology, and society are intimately connected. They a

I agree! I wonder if there's a substantial overlap between the set of people who buy yogurt frequently and the set of people who are averse to ~artificial chemicals~ in their food (tildes denoting a bit of sarcasm at chemophobia).

To elaborate a little bit more: the first generation of LVADs were had large mechanical pumps and were huge -- they could only be implanted in people with a large chest cavity, excluding a large number of patients (especially women) from el

I'm actually really curious -- why would you want to get rid of the ECG as an EEG tech? Do the signals interfere? (I don't know too much about EEG -- happy to learn more!)

Presumably a single lead would still be able to detect certain arrhythmias? I.e. if there are no QRS complexes, then there may be something wrong with the person wearing the device. There are benign explanations for why the signal might be

Thank you for your post. The best talk on CRISPR that I ever heard was ~45 minutes about previous genome editing techniques -- TALENs, Zinc finger proteins, etc -- and ~15 minutes about how CRISPR simplifies the genome editing process. It v

Typically quoted values are (in the current market), approx. $2-3B per product brought to market. Drug development is incredibly difficult -- for very good reasons. The FDA has to be risk-averse in order to protect the health of the public

There's also experimentation to generate hypotheses. I.e., let's sequence the genomes of healthy people and the genomes of people with some disease and see if there is a difference. It's possible to argue that the implicit hy
