Dairy Diary

Yesterday’s kitchen science experiment was this morning’s breakfast! In explaining to my young son about microorganisms that we live with (in our bodies, and as tools of transformation we deploy in various applications like cuisine) I suddenly remembered trying to make yogurt when I was myself very young (although not … Click to continue reading this post

Screen Junkies: Science and Jurassic World

So the episode I mentioned is out! It’s a lot of fun, and there’s so very much that we talked about that they could not fit into the episode. See below. It is all about Jurassic World – a huge box-office hit. movie_science_screen_shotIf you have not seen it yet, and don’t want specific spoilers, watch out for where I write the word spoilers in capitals, and read no further. If you don’t even want my overall take on things without specifics, read only up to where I link to the video. Also, the video has spoilers. I’ll embed the video here, and I have some more thoughts that I’ll put below.

One point I brought up a bit (you can see the beginning of it in my early remarks) is the whole business of the poor portrayal of science and scientists overall in the film, as opposed to in the original Jurassic Park movie. In the original, putting quibbles over scientific feasibility aside (it’s not a documentary, remember!), you have the “dangers of science” on one side, but you also have the “wonders of science” on the other. This includes that early scene or two that still delight me (and many scientists I know – and a whole bunch who were partly inspired by the movie to go into science!) of how genuinely moved the two scientist characters (played by Laura Dern and Sam Neil) are to see walking living dinosaurs, the subject of their life’s work. Right in front of them. Even if you’re not a scientist, you immediately relate to that feeling. It helps root the movie, as does that fact that pretty much all the characters are fleshed […] Click to continue reading this post

LAIH Luncheon with Amy Parish

LAIH_Amy_Parish_10_April_2015_2 For Friday’s Los Angeles Institute for the Humanities luncheon we had a presentation from anthropologist/primatologist Amy Parish (an LAIH Fellow) on the work she’s been doing with bonobos at a zoo in Stuttgart. She updated us on how bonobo societies work (of all the apes, bonobos are our closest cousins, genetically), and then told us about recent experiments she’s been doing with getting them to watch films, giving them control over what they watch, and observing the effects of this on social patterns. (There’s a brief article here about Amy’s recent work.) It was an excellent talk, well attended, with lots of laughter – the result of a pretty potent mixture of food, sex, and humour!

LAIH Field Trip: The Natural History Museum!

LAIH_NHM_Field_Trip_3On Friday the Los Angeles Institute for the Humanities went on another field trip. This time we went to the Natural History Museum. (Click the image for a larger panorama from one of the dinosaur halls.) If you’ve not been there for a while, this is not the museum you remember. It has been transformed, under the leadership of Jane Pisano (President and Director of the Museum, who gave us a splendid talk over lunch), adding several new spaces, a special garden, and new foci in its programming (such as special displays and research programs highlighting urban ecosystems – featuring coyotes, rats, squirrels, possums, Cooper’s hawks, doves, skunks, parrots, etc., (basically my back garden on a typical day, as you know from this blog), along with snakes, bedbugs, termites… The Nature all around us in the city of Los Angeles – fascinating actually.)

We had a tour of some of the spaces, breaking up into two groups (there were around 40 of us) and taking turns on two mini-tours (as we did for the Clark Library in December), one looking at the new dinosaur halls, the other the space dedicated to the urban environments I mentioned above. We learned a lot from our guides about what’s going on in the forefront of research in both […] Click to continue reading this post

Baby Mothra!!!

So I discovered a terrifying (but also kind of fascinating and beautiful at the same time) new element to the garden this morning. We’re having a heat wave here, and so this morning before leaving for work I thought I’d give the tomato plants a spot of moisture. I passed one of the tomato clusters and noticed that one of the (still green) tomatoes had a large bite taken out of it. I assumed it was an experimental bite from a squirrel (my nemesis – or one of them), and muttered dark things under my breath and then prepared to move away the strange coiled leaf that seemed to be on top of it. Then I noticed.

It wasn’t a leaf.

caterpillar_horn_1

It was a HUGE caterpillar! Enormous! Giant and green with spots and even a red horn at one end! There’s a moment when you’re unexpectedly close to a creature like that where your skin crawls for a bit. Well, mine did for a while […] Click to continue reading this post

Screen Junkies Chat: Guardians of the Galaxy

Screen Shot 2014-09-11 at 3.13.03 PMYou may recall that back in June I had a chat with Hal Rudnick over at Screen Junkies about science and time travel in various movies (including the recent “X-Men: Days of Future Past”). It was a lot of fun, and people seemed to like it a lot. Well, some good news: On Tuesday we recorded (along with my Biophysicist colleague Moh El-Naggar) another chat for Screen Junkies, this time talking a bit about the fun movie “Guardians of the Galaxy”! Again, a lot of fun was had… I wish you could hear all of the science (and more) that we went into, but rest assured that they* did a great job of capturing some of it in this eight-minute episode. Have a look. (Embed below the more-click):

Coral Forest

crochet_forest_7Given that you read here at this blog, you may well like to keep your boundaries between art and science nicely blurred, in which case you might like to learn more about the coral reef forests made of crochet spearheaded by Margaret and Christine Wertheim. The pieces mix crochet (a hand-craft I know and love well from my childhood – I got to explore my love for symmetry, patterns, and problem-solving by making doilies) with mathematics – hyperbolic geometry in particular – as well as biology (mimicking and celebrating the forms of corals – and drawing attention to their destruction in the wild). You can read much more about the projects here. I’ve mentioned the work here before on the blog, but the other day I went along to see a new set […] Click to continue reading this post

Fail Lab Episode 12 – Finale

fail_lab_ep_12_still….In which Crystal and many of the crew chill out on the sofa after a long hard season of shows and express some of their gut feelings about the whole business. Well done on an excellent series of shows, Crystal, Patrick, James, and all the other behind the scenes people! (Warning: – This episode may not be for the squeamish!)

Containment Cube

No, not some geometrical artifact of immense power… It is the containment for my next batch of compost. Click for a larger view. I made it last year out of PVC pipes and chicken wire, and it was a huge success (see recent posts with pictures of the produce that has been appearing from that compost batch….) with one design flaw: It was a bit high so that digging in it to turn the forming compost over and so forth was tough on the back – I put my back out for days one time. So I’ve cut it down to a smaller height and now it […] Click to continue reading this post

Whale Song – Your Help Needed

I heard on NPR this morning that there’s a shout out to everyone to help with an interesting scientific project. It is crowd-sourcing in order to achieve certain objectives in science, which is an excellent idea. I wish I could do certain research projects I’m working on in this way – would be fun and quite novel indeed… Crowd-sourcing crowds of processors is maybe the closest I’d get to that. Anyway, it is all about identifying different types of whale song, and as a citizen scientist you’ll […] Click to continue reading this post

Bad Project

bad_project

I’m guessing that a lot of you (especially those doing graduate work in Biology Labs) will just love this video, because you can relate to it. It’s about that frustrating feeling that (for one reason or another, or several) you’re stuck doing the endless project from hell… We’ve all been there. Oh, and it is done in the style of a Lady Gaga video I am told (not having ever seen or heard a Lady Gaga video, as far as I am aware, I can’t attest to this). Video after the fold:

I, For One, Welcome Our New Arsenic-Replacing-Phosphorus-In-DNA Overlords

mono_lakeYeah! This is just the sort of thing I’d hoped that we (human beings) would find soon, in order to strengthen the idea that in looking for forms of life elsewhere, we be not just open to the idea that the basic chemistry for that life may be very different from what we are used to on earth (easier said than done), but that it is maybe even probable that this is what we could find first. Now, given the news today (announced by Felisa Wolfe-Simon and her team in a NASA press conference today and reported on in a paper to appear in Science) we know that it is not just a theoretical construction, but already a reality right here on earth. The researchers have identified a life form with a striking difference. The bacterium (which lives in Mono Lake – see NASA image above right) has DNA (and some other important complex molecules) with a major difference from all other forms we know. phosphorus has been replaced by arsenic!

periodic_tableThis works, by the way, because arsenic is in the same chemical family as phosphorus, being directly below it in the periodic table. Note that this is exactly the sort of thing that has been speculated about a lot in the classic days of science/speculative fiction concerned with alien life, remember? :- Silicon based life forms instead of the Carbon based ones that we know and love on earth. Silicon is again in the same column as […] Click to continue reading this post
