Detailed construction of mouse somatosensory cortex

Brains are so incredibly complex that scientists struggle to express the complexity in words. But this visual reconstruction of the synapses in a mouse somatosensory cortex (sensitive to the stimulation of a whisker) is worth at least a thousand words. Enjoy the journey downward, thanks to the work of the Stanford Medical School.

Why it matters that the Bible is not inerrant

In Jesus, Interrupted: Revealing the Hidden Contradictions in the Bible (And Why We Don't Know about Them) (2010), Bible scholar Bart Ehrman explores many of the contradictions and inaccuracies found in the Bible, and then he comments on what his findings mean. Early in this excellent book, Ehrman invites us to consider the discrepancies in the four Gospels with regard to what happened on the third day after Jesus had been crucified.

Who actually went to the tomb? Was it Mary alone (John 20:1)? Mary and another Mary (Matthew 28:1)? Mary Magdalene, Mary the mother of James, and Salome (Mark 16:1)? Or women who had accompanied Jesus from Galilee to Jerusalem--possibly Mary Magdalene, Joanna, Mary the mother of James, and "other women" (Luke 24:1; see 23:55)? Had the stone already been rolled away from the tomb (as in Mark 16:4) or was it rolled away by an Angel while the women were there (Matthew 28:2)? Who or what do they see there? An Angel (Matthew 28:5)? A young man (Mark 16:5)? Two men (Luke 24:4)? Or nothing and no one (John)? And what were they told? To tell the disciples to "Go to Galilee where Jesus will meet them (Mark 16:7)? Or to remember what Jesus had told them "while he was in Galilee," that he had to die and rise again (Luke 24:7)? Then, do the women tell the disciples what they saw and heard (Matthew 28:8), or do they not tell anyone (Mark 16:8)? If they tell someone, whom do they tell? The 11 disciples (Matthew 28:8)? The 11 disciples and other people (Luke 24:8)? Simon Peter and another unnamed disciple (John 20:2)? What do these disciples do in response? Do they have no response because Jesus himself immediately appears to them (Matthew 20:9)? Do they not believe the women because it seems to be "an idle tale" (Luke 24:11)? Or do they go to the tomb to see for themselves (John 20:3)?

[Page 48] Ehrman's book contains a 40-page chapter called "A World of Contradictions," in which he sets out hundreds of these contradictions and discrepancies. He goes to pains to remind his readers that this is simply a small sampling of the many more such issues one will find if one reads the Bible "horizontally," making a careful effort to compare each version of a story with other versions of the same story in other books of the Bible. Although in some of these differences are insignificant, one will find others that are substantial. One of the discrepancies that Ehrman finds more significant is the debate over the date Jesus dies.

In Mark, Jesus eats the Passover meal (Thursday night) and is crucified the following morning. In John, Jesus does not eat the Passover meal but is crucified on the day before the Passover meal was to be. Moreover, in Mark, Jesus is nailed to the cross at nine in the morning: and in John, he is not condemned in till noon, and then is taken out and crucified.

[Page 27] After producing enough evidence to convince anyone other than the fundamentalist that there are plenty of contradictions and inaccuracies, Ehrman proposes several conclusions we can draw:

1. The Bible is not completely inerrant. There are many errors. 2. Christians "of a certain persuasion--such as many of those among whom I live, in the American South--would ever think to ask such a question": Is it now impossible to be a Christian given these many discrepancies? Ehrman suggests that most Christian faiths will remain "unscathed" by the imperfection of the Bible. 3. It is important to let each author in the Bible "speak for himself and not pretend that he is saying the same thing as another." Urban points out that each of the authors has his own agenda, and these become visible when we read each author separately and carefully. Erhman goes to great pains to distinguish the writings of the four Gospel authors, and this careful analysis has the effect of humanizing these authors and their writings. 4. It is impossible to read the books of the Bible as "disinterested historical accounts. None of them is that." At this point, Ehrman offers this thought experiment: "what would you do as a judge in a court trial in which you have conflicting testimony from eyewitnesses? One thing you would certainly not do is assume that each witness is 100% correct."

If there is an overall theme of Ehrman's book, it is that people should stop reading the Bible with the assumption that each of the authors is basically saying the same thing. Ehrman contrasts this "harmonizing approach" to reading the Bible, which is based upon emotional reading, to the approach he recommends, the "historical-critical approach." This latter approach assumes that the Canon of Scripture--

"[T]hat is, the collection of the books into one book considered in some sense to be authoritative for believers--was not the original form in which the biblical books up.. When Paul wrote his letters to the churches he founded, he did not think that he was writing the Bible. He thought he was writing letters . . . . These books were written in different times and places, under different circumstances, to address different issues; they were written by different authors with different perspectives, beliefs, assumptions, traditions, and sources.

Welcome back to the United States. Give me your laptop and your passwords.

Glenn Greenwald has written about the federal government's common practice of seizing laptops and smartphones of American citizens who are re-entering the United States and reviewing their private data. Amazingly, our government is seizing this personal data without probable cause and even without reasonable suspicion:

When you really think about it, it's simply inconceivable that the U.S. Government gets away with doing this. Seizing someone's laptop, digging through it, recording it all, storing the data somewhere, and then distributing it to various agencies is about the most invasive, privacy-destroying measure imaginable. A laptop and its equivalents reveal whom you talk to, what you say, what you read, what you write, what you view, what you think, and virtually everything else about your life. It can -- and often does -- contain not only the most private and intimate information about you, but also information which the government is legally barred from accessing (attorney/client or clergy/penitent communications, private medical and psychiatric information and the like). But these border seizures result in all of that being limitlessly invaded. This is infinitely more invasive than the TSA patdowns that caused so much controversy just two months ago.
But how often are these e-strip searches occurring?
[T]his is happening to far more than people associated with WikiLeaks. As a result of writing about this, I've spoken with several writers, filmmakers, and activists who are critics of the government and who have been subjected to similar seizures -- some every time they re-enter the country.
But this is the tip of the iceberg:
A FOIA request from the ACLU revealed that in the 18-month period beginning October 1, 2008, more than 6,600 people -- roughly half of whom are American citizens -- were subjected to electronic device searches at the border by DHS, all without a search warrant.
I highly recommend reading Greenwald's detailed article for the reaction to this practice by a smattering of members of Congress and by a few court decisions. The sad bottom line is that there is no political momentum to condemn and bar this practice, even in the context of ubiquitous rhetoric regarding the need to limit the power of the federal government.

I love Sara Tavares

I'll try to get myself under control. But you see, I've been sitting at my desk for 15 hours today, creating an extremely complicated legal document that is finally finished. For the last 2 hours of this almost-torture, I have been listening to an album called Xinti by Sara Tavars. Gad, such intense, gorgeous music! (See, I even used an exclamation point). I've never met Sara, but . . . her voice . . . her fantastic song-writing and that excellent guitar playing . . . This is music that removes you from wherever you are and puts you in a place where everything is OK. I've never met Sara, but I love her. She's got me wrapped around her finger. This is pathetic, in a good way. When visitors come over to the house when Xinti's playing, they all demand to know who is making that incredible music. Sara is. And it's really daunting to try to describe exactly what kind of music she creates. Here's the description of her work from Amazon:

Brimming with Cape Verdean guitar licks, Angolese rhythms and warm Portuguese vocals, Sara never sounded more intense. This is a startling collection, packed with surprises that displays how progressively richer and more expansive Sara Tavares' vocal repetoire has become since her previous album "Balance". Her songs are lyrcial, sensual and more textured. They are intimate but also wrapped in irresistibly funky rhythms drawn from the Cape Verdean / African / Brazilian / Caribbean diaspora.

Have you ever listened to music of that genre? Maybe it's time you tried. Or buy Sara's album as a gift for someone you love, and they will love you back. It's unfair, because Sara did all of the work to make that music, and all you had to do was buy it. Here's a cut called "Sumanai" from Xinti (and you'll find quite a few of her other tunes on Youtube):
