The Great News Of The Day
I presume you’ve heard the news by now, concerning stem cell research in the USA. If not, listen to and read some of the NPR reporting on it here (by Julie Rovner

Happy 200th Birthday, Darwin!
Well, as you’ve read here and elsewhere, this is a big year for (among other things) Darwin celebration. There are all sorts of wonderful essays, documentaries, discussions, lectures and so forth all around. Be sure to look at some of this work, and get involved. In addition to it being the 150th anniversary of the release of the Origin of Species, it is Charles Darwin’s 200th birthday year, and the actual birthday date is today, the 12th February.

Darwin in the Air
You’ll begin to notice a lot of discussion of Charles Darwin soon. Why? It is his 200th anniversary, and also 150 years since his Origin of Species was published, and so many people and organizations will be celebrating those landmarks. I did a couple of posts last year on Darwin that are worth a look, one about Darwin’s presentation of the evolution idea to the Linnean Society (150th anniversary of that last year) and the other about the wonderful Darwin Online project. See here and here.
Earlier this week I noticed that BBC Radio 4’s excellent series In Our Time (which I’ve mentioned a number of times here and will again) did a four part special documentary on Darwin. I’ve not listened to it yet, but I’ve a feeling it’ll be good. (I’ll be dropping all four parts onto my phone for listening to in those idle moments on some travel I’m about to embark upon.)
Snipping some of the synopses: […] Click to continue reading this post
Prize Watch
Don’t forget to be looking out for the other Nobel Prizes announced this week. Monday saw the Physiology or Medicine Prize go to Harald zur Hausen for work on the human papilloma viruses (which cause cervical cancer), and to Françoise Barré-Sinoussi and Luc Montagnier for work on the human immunodeficiency virus. Announcement and more details here. Meanwhile, today’s Chemistry Prize was to Osamu Shimomura, Martin Chalfie, and Roger Y. Tsien for the discovery and development of the green fluorescent protein, GFP. Details here.
No, no, no. The Chemistry prize was not for the discovery of a substance that’s just pretty and sparkly-glowy. (Although, you know… maybe that is a good reason on its […] Click to continue reading this post
E.Coli Stories
Not long ago, science writer Carl Zimmer spoke at the Zócalo series. He was talking about the subject of his new book, E. Coli, and wove a lovely story of how the E. Coli have taught us so much about life over the years, and how they continue to do so. So much of what we know about the workings of DNA, for example, came down to studies of a very clear model system, and E.Coli was the system chosen by Biologists (and Physicists interested in fundamental issues surrounding the nature of life, DNA, etc.) (Updated attribution: Image left is a painting from here. Worth looking at that site for more such images.)
The talk, for a general audience, is highly informative. It is only about an hour long, and worth your time. It was broadcast last night, and I found it rather good indeed. I […] Click to continue reading this post
Oh My God, It’s Full of Stars!
I really hope the scientists said that when they found this. Really. It’s a mountain, underwater, colonized by millions of starfish. Amazing.
It is at the Macquarie Ridge, near New Zealand. […] Click to continue reading this post
The Darwin Online Project
On NPR the other morning, I heard a piece about the Darwin Online Project. It sounds just amazing. I hope you find time to explore the site.
It has all sorts of fascinating things that you can download or view in the above (click for larger) manner (your very own copy of the Origin of Species, perhaps, or parts of his diaries and notebooks…), and is quite a treasure trove of one-stop-shop (but free) Darwin data. (There are even some of (his wife) Emma Darwin’s recipes.) The site is here.
Very importantly, the collection shows Darwin’s work in development, and not just the […] Click to continue reading this post
Liberated Penguins
[Update:- NB: This was an April Fool joke. -cvj]
Well, I learned recently* that the BBC wildlife program makers have done it again, breaking new ground in scientific discovery while making a new series. Quite amazing this time. From the Daily Telegraph website:
The BBC will today screen remarkable footage of penguins flying as part of its new natural history series, Miracles of Evolution.
Also:
The programme is being presented by ex-Monty Python star Terry Jones, who said: “We’d been watching the penguins and filming them for days, without a hint of what was to come.
“But then the weather took a turn for the worse. It was quite amazing. Rather than getting together in a huddle to protect themselves from the cold, they did something quite unexpected, that no other penguins can do.”
Above right (click for larger view) is a screen shot that I took of the incredible footage […] Click to continue reading this post
Police Sting Operation
I find this a bit sad, although most people will say “they’re only bees”. They (and lots of other beekeepers with their bees on trucks) were in the area to help with pollinating crops. I’m very enamoured of the idea that we still need bees to be brought in to … Click to continue reading this post
Notes from the Compost Heap
Continuing a bit about the microbiology to be found in the garden, I did a post not so long ago on Correlations giving an update about the composting system I started a while ago (post on that here). You might find it interesting, and so I thought I’d let you know about it. It is here.

Stem Cell Timeline
Not surprisingly, there’s been a lot of interesting chatter about the recently announced stem cell research results I blogged about earlier. I did a longer blog post over on Correlations that might interest you (I managed to think of the pun for the title that I knew was in there somewhere, but could not manage it this morning over here).
Mentioned there are two more NPR items I thought were of note: […] Click to continue reading this post
Stem Cell News
You may have heard about the new stem cell breakthrough in the news. It seems to be quite significant – researchers (at Kyoto University and at Wisconsin-Madison) have managed to make human skin cells into stem cells (following on work done in mouse some announced some months back). If interested in the details (as I’m sure you are) you can read more about it in an AP story on the NPR web site here. (Yahoo’s version has pictures, such as the nerve cells above left from the Kyoto group. – try and spot the odd one out in their 14 image slide show.)
There was also a very informative chat about it with one of their science correspondents, Joe Palca, on Morning Edition, and you can listen to it here. There’ll […] Click to continue reading this post
A Flawed Model
News report on research into the fundamental constituents of little boys. It seems that the “frogs, snails and puppy dog’s tails” model may not stand up to experiment: -cvj (Thanks Sarah!)
Many Mysteries Left
I spotted an interesting article by Faye Flam in the Philadelphia Inquirer about research into left-handedness. I confess that I do not know really what to make of it, but it is an interesting survey of some research in the area, with several surprising facts. Thought I’d pass it on … Click to continue reading this post
Inside Out from the Inside
Last night’s Categorically Not! – Inside Out event was just great. The three topics contrasted really nicely, were very well presented as individual topics in their own right, and there were resonances between the different topics through the main umbrella theme – “Inside Out”.
Science writers Sandy Blakeslee and her son Matt Blakeslee did a sort of tag team presentation, taking turns to build up several aspects of the subject (covered in their new book “The Body Has a Mind of Its Own”) of one’s sense of self and that all-so-important division between inside (ourself) and outside (the rest of the universe) that we make with our minds. 
It’s very dynamic, of course – you extend it a lot when you use tools, from a fork when eating to the car you’re driving in (everyone grunted in recognition when Sandy mentioned how you have the instinct to duck when driving under a low ceiling in a parking garage….). One of the things that I think resonated most with the audience is the description of the work on showing how many celebrated “out of body” experiences that people get have a foundation in […] Click to continue reading this post
