"Now we are starting to work with organisms that are more likely to appear in a hospital, like staph and influenza, and we have our sights on Clostridia difficile, Pneumococcus aeruginosa, Acetinobacter baumanii and an alarming number of other bacteria that are resistant to antibiotics. We are also working on influenza, which has a convenient little feature called M2e."




"I was not writing for an audience. I was writing for myself. I was making something for myself. And then just hoping that maybe somebody else had similar interests. But of course, in the early days, 75 percent of my audience would walk out after 20 minutes. And being a young Turk, I thought that was great, because it proved I was making real stuff. But I still have a very ambivalent attitude towards the audience, which is one of the things I've always hated about the theatre, because I believe that people, en masse, always have a reaction that is lower and less interesting than any individual person that you can confront and have a relationship with."

"The parasite my lab is beginning to focus on is one in the world of mammals, where parasites are changing mammalian behavior. It's got to do with this parasite, this protozoan called Toxoplasma. If you're ever pregnant, if you're ever around anyone who's pregnant, you know you immediately get skittish about cat feces, cat bedding, cat everything, because it could carry Toxo. And you do not want to get Toxoplasma into a fetal nervous system. It's a disaster."

"For the past twelve years my research team has been using all the brain research tools at its disposal, from functional MRI to electro- and magneto-encephalography and even electrodes inserted deep in the human brain, to shed  light on the brain mechanisms of consciousness."

"Inflation does not provide a natural explanation for why the early universe looks like it does unless you can give me an answer for why inflation ever started in the first place. That is not a question we know the answer to right now.  That is why we need to go back before inflation into before the Big Bang, into a different part of the universe to understand why inflation happened versus something else. There you get into branes and the cyclic universe. ... I really don't like any of the models that are on the market right now. We really need to think harder about what the universe should look like."

"We are apparently now in a situation where modern technology is changing the way people behave, people talk, people react, people think, and people remember. And you encounter this not only in a theoretical way, but when you meet people, when suddenly people start forgetting things, when suddenly people depend on their gadgets, and other stuff, to remember certain things. This is the beginning, its just an experience. But if you think about it and you think about your own behavior, you suddenly realize that something fundamental is going on. There is one comment on Edge which I love, which is in Daniel Dennett's response to the 2007 annual question, in which he said that we have a population explosion of ideas, but not enough brains to cover them."

Evolutionary Psychology

Cognitive instincts for cooperation, institutions & society

"There's a mismatch between the modern versus ancestral world. Our minds are equipped with programs that were evolved to navigate a small world of relatives, friends, and neighbors, not for cities and nation states of thousands or millions of anonymous people. Certain laws and institutions satisfy the moral intuitions these programs generate. But because these programs are now operating outside the envelope of environments for which they were designed, laws that satisfy the moral intuitions they generate may regularly fail to produce the outcomes we desire and anticipate that have the consequences we wish. ..."

Language and Human Nature


"Language is an adaptation to the "cognitive niche". It facilitates exchange of information, negotiating of cooperation. But indirect speech (polite requests, veiled threats & bribes, sexual overtures) are a puzzle for the theory that language is an adaptation for efficient communication. Language is an adaptation to the "cognitive niche". ..."

Beauty's Child: Sexual Selection, Nature Worship and the Love of God


"...I want to engage you in a discussion of the deep history of beauty. By deep I mean as seen from an evolutionary perspective. I am an "evolutionary psychologist".  I believe that to understand and fully appreciate human mental traits, we need to know why they are there — which is to say what biological function they are serving.  Evolutionary psychology has been making pretty good progress. But, as we say, "there are still some  elephants in the living room" — big issues that no one wants to talk about. And human beings worship of the beautiful remains  one of the biggest."
