Whilst out at Tesco this morning, getting some fresh pineapple for breakfast, I also picked up some Factor 50 sun block to use when in San Francisco for WWDC 09 in early June. I’ve been sun burnt twice in California. Once quite badly on the forehead in San Diego, and then on the arms and neck in San Francisco. Not this year 🙂

President Obama on science
More change 🙂
If anyone doubted that change has come, and come to science, they need to watch this video. We’ve been waiting a long, long time for a president to take this kind of interest in furthering the cause of science in our country. His budget calls for a doubling of our nation’s investment in basic research in the coming years: “No one can predict what new applications will be born of basic research: new treatments in our hospitals; new sources of efficient energy; new building materials; new kinds of crops more resistant to heat and drought.” “It was basic research in the photoelectric effect that would one day lead to solar panels. It was basic research in physics that would eventually produce the CAT scan. The calculations of today’s GPS satellites are based on the equations that Einstein put to paper more than a century ago….”

Bill Maher Mocks Texas Gov. Perry Over Evolution and Swine Flu
Mocking the stone age science at the Texas State Board of Education has now gone viral — late-night comedians have the rest of the country laughing at us. Bill Maher de-pantsed the governor on last Friday’s episode of his HBO series Real Time with Bill Maher: “He [Perry] appointed a creationist to head the Texas State Board of Education, which is shocking. Texas has a board of education?!?”
Shaving: A technical solution?
I hate shaving. I’ve Twittered about it a few times. Beard hair, especially just under my jaw line and on my neck, grows very quickly and mostly dark. If I shave in the morning then by lunchtime there will be significant regrowth of the hair. A 12 o’clock shadow! Not only that the hair is like stiff wire and rubbing a finger over it is actually painful to the face skin. The shaving bumps and razor burn I get are quite painful as well. It’s not quite as bad as the Pseudofolliculitis barbae that some people get, but still a pain in the neck (pun intended!) I think that the hair composition changed a bit after I had surgery for testicular cancer. Maybe my hormone levels went a bit haywire for a bit. I don’t know. I wasn’t tested for testosterone levels at the time.
I’ve been a long advocate of the mantra there is a technical solution for everything. It’s a bit of a glib phrase I know. But it suits my view of the world. If you define it widely enough then the phrase can take in braces for teeth straightening, surgery, lots of things.
So, is there a technical solution for the shaving problem? Research shows that there is. Laser hair removal. In particular a technique that uses a laser with a certain wavelength of laser light that is meant to work really well on coarse, dark male beard hair. It’s known as the Lightsheer Diode Laser System. There are lots of sites on the Internet where people outline their successes (or not – mostly successes though) with beard removal using with the Lightsheer machine. Apparently it works due to the melanin pigment in dark hair follicles absorbing the energy in the laser light. This heats the follicle and destroys or impedes its ability to produce new hair. It seems it doesn’t work on light coloured hair or hair that has gone grey or white as there is not enough melanin to absorb the energy.The science behind it is interesting stuff. Not sure why I didn’t think of this before. I lost the hair on my chest and abdomen during my radiotherapy. That grew back after a while. With Lightsheer it takes several sessions spread out over about a year to provide a complete zapping.
Do I hate shaving and the associated razor irritation enough to try getting it lasered? I don’t know. My beard now grows with colours like a Persian carpet. Not all the hairs are as black as they were 20 years ago. The laser might not work on the light coloured hairs, and definitely won’t work on the white/grey hairs. But then again maybe removing the majority of the hair, which is dark and susceptible to the laser, would be enough. It’s also meant to be painful. Do I have the balls for it? I don’t like pain! There is also the societal aspect. Is it socially acceptable for blokes to get their beard hair permanently removed? I don’t see why not. What’s the difference between a few laser removal sessions and shaving everyday?
Anyway. I’ll have to have a think. It’s meant to be quite expensive as well.
An enzyme behind cancer spread found
This is interesting. If blocking this single enzyme does stop cancer metastasis then it’ll be a real breakthrough. AS long as the cancer is found early before it can spread of course. Which is why you need to get anything suspicious checked out as early as possible. False alarms and wasted trips to the doctor are better than the alternative.
Institute of Cancer Research scientists have found that an enzyme called LOX is crucial in promoting metastasis, Cancer Cell journal reports.
Drugs to block this enzyme’s action could keep cancer at bay, they hope.

Green light for US stem cell work
More change we can believe in 🙂
US regulators have cleared the way for the world’s first study on human embryonic stem cell therapy.
The move comes three days after the inauguration of President Barack Obama who has been a strong supporter of embryonic stem cell research.

Happy 2009
Just want to wish everyone who stumbles upon this blog a Happy 2009. If you want to be where the action is online in 2009 joint Twitter.
I think 2009 is going to be very historic for several reasons. Number 1 being the inauguration of Barack Obama. The fact that he is African American is an incidental in my opinion. The best thing about Barack Obama is that he is an intellectual. He gets that it is okay to listen to experts in various fields and that empirical evidence isn’t a taboo.
Other highlights in 2009 will be the 200 year anniversary of Charles Darwin’s birth and the 150 year anniversary of the publication of his seminal work On the Origin of Species by Means of Natural Selection.
The world has been on a path to a a better place after the work of Darwin, and Wallace it should be said.
Obama’s new science advisor on Letterman last April
Last April John Holdren, who will be Barack Obama’s chief science advisor, was on Letterman. You can see a video of it here. It’s well worth watching.
It’s like finding water after years in the desert
Barack Obama talked about science and introduced his science team in his weekly address. See video below. Could we be about to witness a new mini enlightenment after the regression of the Bush years. I think so. It is incumbent on all of us who value rationality, both in the USA and also the wider world, to step up to the plate and advance rational evidenced based thinking and policy.
I wonder how much complaining we’ll hear from the war on Christmas crowd for the Happy Holiday’s closing remark!

The end of a great use of Twitter 🙁
