New light has been shed on proteorhodopsin, the light-sensitive protein found in many marine bacteria. Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have demonstrated that when the ability to respire oxygen is impaired, bacterium equipped with proteorhodopsin will switch to solar power to carry out vital life processes.
In the bayous of eastern Arkansas, amidst ancient trees both living and dead that provide nourishment to creatures of the swamp, hangs a high-tech sentinel patiently waiting to capture video of an elusive bird once thought to be extinct. Developed by researchers from the University of California, Berkeley, and Texas A&M University, the high-resolution intelligent robotic video system installed in the Bayou DeView area of the Cache River National Wildlife Refuge in Arkansas is part of a major effort to locate the ivory-billed woodpecker in its historic habitat, the bottomland forests of the southeast United States.
Having a basic knowledge of scientific principles is no longer a luxury but, in today’s complex world, a necessity. And, according to a Michigan State University researcher, while Americans are holding their own, they are not even close to where they should be.
I’m sure PZ is inundated with e-mails from readers asking for a real evo-devo explanation, but in the meantime read the news report and see the picture:
The 104th edition of The Tar Heel Tavern is up on Freelance Writing for Nonprofits. The theme is ‘paying tribute’.
Next week, the carnival will be on my old digs, Science And Politics, with no particular theme or topic. Just send your week’s best to: Coturnix AT gmail DOT com
Use new media to influence old media, for example, and read the Web to find out what people are talking about outside the campaign bubble. Understand that the news cycle is dead and that stories don’t just fade away anymore; the Web operates in an eternal present, where information gets posted in close-to-real-time and remains a click away forever.
Dr. Aaron B. Lerner, a Yale dermatologist and the leader of a team of researchers who discovered melatonin, a powerful hormone regulating human sleep-wake cycles, died on Feb. 3 in New Haven. He was 86.
The cause was complications of Parkinson’s disease, his family said.
In 1958, Dr. Lerner, an expert on skin pigmentation disorders who trained in both chemistry and medicine, led a Yale team that isolated a hormone from the pineal gland within the brain.
In laboratory experiments on frogs, the researchers found that the compound could lighten skin color and theorized that it might have applications in treating human skin disorders. Dr. Lerner named the hormone melatonin, and the team’s findings were announced in The Journal of the American Chemical Society.
Subsequent investigations revealed that melatonin did not hold the key to treating disruptions in skin pigmentation like vitiligo. Research by others has since uncovered the hormone’s importance in maintaining the circadian rhythm of rest and wakefulness, and it is now used to treat sleeplessness and jet lag.
Dr. Lerner later developed a transplantation therapy for vitiligo, a disorder that affects about 1 percent of the population and destroys pigment-making cells. The condition may be disfiguring and leaves light-colored patches around body openings like the mouth and eyes, but does not otherwise affect someone’s health. After removing a postage-stamp-size patch of a patient’s normal skin, he grew the cells in culture, then transplanted them to damaged areas. The result was a more uniform complexion covering the abnormal shades of skin, and it was often accompanied by a reduction in social stigma for the patient. The technique was advanced in the 1980s and remains in use, even as vitiligo is more commonly treated by drugs and exposure to light.
In other work, Dr. Lerner isolated another compound — melanocyte-stimulating hormone, or MSH, which he obtained from the pituitary glands of pigs — and studied its skin-darkening effects. Earlier, while still a graduate student, he and another researcher, G. Robert Greenberg, isolated a protein that appears in the blood at low temperature, a monoclonal antibody known as a cryoglobulin.
Aaron Bunsen Lerner was born in 1920 in Minneapolis. In 1945, he received his medical degree and a doctorate in physiological and physical chemistries from the University of Minnesota. After teaching at the University of Michigan and the University of Oregon, he joined Yale as an associate professor of medicine in 1955. Dr. Lerner became the first chairman of Yale’s dermatology department in 1958. He remained chairman until 1985, and was named a professor emeritus of dermatology in 1991.
I am also hosting The Tarheel Tavern this weekend, the premiere carnival of North Carolina bloggers. My theme is “Paying Tribute.” Since we are close to President’s Day, and nobody I know actually honors our presidents on the day, I suggest we honor a person in our lives or history who really does deserve an extra bit of love and respect from us, via our blogs. NC bloggers can submit a post to me by Saturday night at kivi AT writingfornonprofits.com.
After writing her side of the story in Salon, Amanda Marcotte is quite busy in the media these days, making various apperances on radio, including NPR’s DayTo Day next week. She will also be joining TPM Cafe and has a post up on Huffington Post: Think Tanks, 503s and Rush Limbaugh–What’s The Real ‘Soft Money’
Now, Melissa McEwen published her take on the whole affair in Guardian: My life as a rightwing target. Check the comments and tell me that the Rightwingers are not delusional, dangerous psychopaths. And they are in the White House right now. (Oh, and if anyone thinks that Amanda and Melissa were wimps for quitting, you should read this)
I think that Donohue has jump-started their careers. And what they will do, now that they have more prominent soap boxes, is reveal to everyone how the Rightwing sliming machine works, how it is financed, and how it can be counteracted.
What Donohue has done successfully is make the story of Amanda and Melissa be framed as Bloggers vs. Edwards. And it pains me to see how many on the Left bit that bait (and hook and sinker). It is a multi-faceted story about the Rightwing sliming machine and how it works. It is also a story about the way the Party Establishment (both Left and Right) resists the democratization of the political process (it is the old-Millennium, dinosaur, computer-illiterate campaign managers who, I guess, wanted to get rid of the bloggers in the first place until Edwards stepped in and said No). It is also a story about the way Media resents the citizen journalism and the many-to-many conversation of the new media unrestrained by the he-said-she-said tropes. It is a story about the Beltway protecting their turf against the “rubes.”
If this is the future, we are now in the middle of the war between the powers of the Old-Way-Of-Doing-Things that tends to protect the old power sturucture, and the New Way that gives the little man a say and overturns the old power structure.
Check out this Salon editorial as an example of this turf-protection. It is all about silencing the people. As I stated before, the netroots ARE the grassroots. It is the same people who knock on doors and donate money. Except, this time around, they do not just take orders and write checks, they have the means to talk back and tell the campaigns what to do (or to shove it). Of course the campaign managers used to the old way of thinking are afraid of the new world.
Here is another example from ABC: Loose Lips in the Blogosphere Don’t Sink Presidential Ships
I hate the subtitle – what do they mean by “even Edwards” when everyone (including the techies with no political axe to grind) agrees he is the leader on the use of Internet and netroots: his website is by far the best, he announced to the bloggers first, then by video on YouTube, then by Video and post on his own website, and only the next day announced to the MSM dinosaurs down in New Orleans. He hired and (stood by in spite of calls for their heads) two of the most outspoken and popular feminist bloggers. He is prominently present and active on all social networking sites, not just MySpace, YouTube, Flickr, Del.icio.us and Facebook, but also the second-tier places, like Gather.
There are 199 Groups on Facebook for Edwards. The two biggest ones have 2,126 members and 1,849 members respectively – the rest are smaller, mainly due to being geographically restricted. Barack Obama has more than 500 groups, with the biggest one having 5,002 members and the others being small, local chapters. So, even including the overlap (people joining more than one group), there is not such a huge advantage for Obama on Facebook as the Media likes to point out. Edwards is right behind.
And he is the first candidate on Second Life. Yes, on Second Life! If you have no idea what that is, or if you want to know what techies and politicos think, follow the links here, here, here, here, here, here and here.
Also, note that in fundraising, Hillary Clinton is expected to raise $100 million from the Beltway power-mongers and Holywood, Obama somewhat less, from the same sources, while Edwards is expected to raise about $50 million mostly from small online donations. He is killing all other candidates together in such donations through ActBlue ($860,861.35, compare that to Richardson’s two separate funds at $284,916.57 and $10,154.85 and Obama’s $16,885.56).
Oh, and if you do not believe Edwards stood by his bloggers and does not understand the netroots, I hope you watched the Situation Room earlier today (there should be a YouTube clip of it here soon). Listen to his defense of the bloggers and phrases like: “I stood by them,” “new brave world with the net and the blogosphere,” “a powerful world which will have a huge effect,” “grassroots politics at it’s best,” etc. Here is the clip:
As for the bloggers, Jude, aka Iddybud, has an excellent take on the bloggers saga and Dave Neiwert takes another look at the ‘Christofascists’ who are Unhinged indeed. Also read important posts by Ampersand, Jeffrey Feldman and Richard Cranium.
And finally, let’s look again at the posts for which Amanda got so much flak from Donohue and his ogre minions. They are about Plan B. Here are Part I and Part II.
She is not the only blogger explaining Plan B and why the opposition to it by wingnuts (including but not only Catholics) is bad politics and bad public health. For instance, Ema of Well-Timed Period blog wrote at least two posts on it here and here. PZ Myers of Pharyngula wrote about it here, here and here. DarkSyde of DailyKos wrote about it here and Bitch, PhD wrote about it many times, most recently here.
Is there any difference between these posts? They all get the facts about Plan B right. They all demonstrate that the opposition to it is hypocritical and based on mysogyny. And they are all written in typically blogospheric colorful language. Yes, those who deserved to be insulted got insulted. Now, tell me. If any campaign hired any of these bloggers to work on the technical and esthetic parts of their campaign blogs, don’t you think Donohuse and his basement monsters would not come out against them? Of course they would – their goal never was to destroy the careers of Amanda Marcotte and Meilissa McEwen. Their goal is to undermine a Democrat – any Democrat – running for President because their job (for which Donohue is paid $300,000) is to go on TV and lie for Republicans. It has nothing to do with these two bloggers, it has to do with silencing the voices of the people who are actually telling the truth as it is, as opposed to The Truth as the conservatives want “to create” for themselves.
It does not matter if you care or not about Behe’s silly creationist claims, but they sure provide great starting points for cool science blog posts. Here, Ian Musgrave uses this tactic to educate us all about the ancient roles of some molecules we use in blood-clotting, but invertebrete Chordates use for other functions.
This is less than a year old (March 05, 2006), but instructive now that the campaigning has actually started…Also, click on the spiderweb icon to see interesting comments on the original post.
I use it all the time. Today’s Merriam-Webster Word Of The Day:
grok \GROCK\ verb
: to understand profoundly and intuitively
Example sentence:
No matter how many times I try to explain it, my grandmother just can’t grok what a blog is and why anyone would want to read one.
Did you know?
“Grok” may be the only English word that derives from Martian. Yes, we do mean the language of the planet Mars. No, we’re not getting spacey; we’ve just ventured into the realm of science fiction. “Grok” was introduced in Robert A. Heinlein’s 1961 science fiction novel Stranger in a Strange Land. The book’s main character, Valentine Michael Smith, is a Martian-raised human who comes to earth as an adult, bringing with him words from his native tongue and a unique perspective on the strange, strange ways of earthlings. “Grok” was quickly adopted by the youth culture of America and has since peppered the vernacular of those who grok it, from the hippies of the ’60s to the computerniks of the ’90s.
Words have meanings; they express ideas and ideas are important. The word “surge” came with the idea of a relatively small short-term increase in force that would be effective. Such previous troop increases had been ineffective and the joint chiefs saw no reason that this one would be effective either. The actual proposal called a “surge” was the opposite of what the word meant. In short, the very use of the word “surge” was a lie.
People all over the country noticed the “surge” framing immediately, and quickly — and accurately — reframed the President’s proposal as an “escalation.” Escalation is a strategy employed by an apparently superior power that is losing when it was expected to win. It is the strategy of raising the level of force and, hence, of violence, bringing in more troops, deepening one’s commitment to a strategy already in place, raising the bar for what is to count as “success” and for the removal of troops.
In recent years, many progressives have been learning that facts alone — without framing that conveys their context — are not enough. This lesson is forcefully demonstrated in cases in which conservatives tenaciously resist the use of language that reveals truth and lays bare their failed policies. The latest examples of this include a proposed non-binding Senate resolution opposing the deployment of greater numbers of troops to Iraq and an international report on the future of the world’s climate.
The $2.9 trillion budget that the Bush administration proposed this week cuts the budget for public broadcasting by nearly 25 percent. The cuts have already prompted the reaction that the Bush administration surely expected: progressive groups are asking their members to lobby Congress to protect PBS and NPR. Are progressives falling into a right-wing trap that reinforces the conservative framing of PBS and NPR as tools of a “liberal elite”?
Conservatives have long invoked family values to promote wedge issues and win elections, but the implications of family values on our politics and society run far deeper than campaigns and elections. In the Rockridge Nation video that we have just released, George Lakoff examines the extraordinary influence of James Dobson on parenting in America. He also discusses progressive and conservative conceptions of family values, and why progressives must overcome the conservative dominance of this subject.
“Regressive evolution,” or the reduction of traits over time, is the result of either natural selection or genetic drift, according to a study on cavefish by researchers at New York University’s Department of Biology, the University of California at Berkeley’s Department of Integrative Biology, and the Harvard Medical School. Previously, scientists could not determine which forces contributed to regressive evolution in cave-adapted species, and many doubt the role of natural selection in this process. Darwin himself, who famously questioned the role of natural selection in eye loss in cave fishes, said, “As it is difficult to imagine that eyes, although useless, could be in any way injurious to animals living in darkness, I attribute their loss wholly to disuse.”
The warming most global climate models predict will do more harm than simply raise the sea levels that most observers fear. It will make drastic changes in fragile ecosystems throughout the world, especially in the Antarctic. A warming trend during the last few decades in the Antarctic Peninsula has already forced penguin populations to migrate south and perhaps diminished the abundance of krill that are at the base of the massive food chain at the bottom of the world.
Being female can be a risky business, especially if you are a Marula tree in Africa receiving the attention of elephants. The tasty, nutritious and vitamin C-rich Marula fruits are much sought after by both man and animals. It is a stable “wild food” and base for the popular Amarula liquor. But Marula has separate male and female trees so fruiting females attract browsing elephants, which cause damage to branches and bark.
Remember this, and use it next time you are debating religion, politics or pseudoscience:
“….someone wearing nothing but a Peter Gibbons-esque cheerful smile and having nothing but kind words for anyone will always be wrong if he says 2 + 2 = 5, and that if I call him a douchebag on wheels and use terms like “donkey punch” in the course of correcting him, it doesn’t change who is right; it just changes the input into the popularity contest…
Global warming change is the topic of a symposium, free and open to the public, in NC State’s Campus Cinema, located in Witherspoon Student Center, February 26-28, and featuring excellent speakers. Elizabeth Kolbert, author of FIELD NOTES FROM A CATASTROPHE, opens the meeting on Monday, Feb. 26, at 7:00 p.m.

Raleigh officials have teamed up with Cree, Inc. in Research Triangle Park to save money and help the environment. Raleigh public works employees will test and implement Cree’s Light Emitting Diode lighting components across the city.
In a pilot program late last year, LED lights were installed in a parking deck downtown. Progress Energy, the city’s primary energy provider, said that the floor equipped with LED lights used more than 40 percent less energy than the standard lighting system. Also, the quality of the lighting was greatly improved, according to Progress Energy’s research.
As part of the initiative, more Cree lighting components will be tested in other applications, such as street lights, architectural and accent lighting, and pedestrian and walkway lights, over the next 18 months. If significant energy savings are found, Raleigh will convert permanently to LED lighting.
While switching to LED in public spaces and governmental offices, as well as, hopefully, a bandwagon effect of this on businesses and private homes, will have a very positive effect on the lowering of energy consumtion an cost and the air pollution, I sure hope they use this opportunity to redesign the city lighting in such a way as to reduce LightPollution as well.
I also hope that other cities will follow suit. How about a LED-only Triangle region? Or LED-only North Carolina? Set the example for the rest of the country.
[Hat-tip]
P.S. This does not mean banning incadesent lightbulbs. They have their uses. How can you keep a reptile in a terrarium without an incadescent light? Only by wasting even more energy and polluting more by installing a heater.
I have read “The God Delusion” by Richard Dawkins and “Breaking The Spell” by Daniel Dennett a couple of months ago, could not bear to slog all the way through “The End of Faith” by Sam Harris, and am still waiting to get my copies of “God: the Failed Hypothesis” by Victor Stenger and “Evolving God: A Provocative View on the Origins of Religion” by Barbara J. King. I was going to write a big meta-review of all of them together, perhaps adding in “Darwin’s Cathedral” by David Sloan Wilson as an anti-toxin to the Dawkins/Dennet naive understanding of evolution (and just plain old nastiness towards the idea of demic selection in particular and towards the idea of hierarchy of levels and units of selection in general).
But more I wait, harder it will be to get something original out. Yesterday, Sean Carroll scooped me in my idea to use the concept of OvertonWindow to explain the usefulness of most (if not all) of these books, particularly the Dawkins book. You should really go and read how Sean put it together and I will, once I get through all the books, try to find a different angle.
This is the last in the 16-post series of BIO101 lecture notes for a speed-course targeted at adults. As always, I welcome corrections and suggestions for improvement (June 17, 2006)…
Litbrit (also check the comments on the re-post here) tells it beautifully:
That is why so many of us have spoken out–we don’t want government telling us what we should believe and how we should run our private, personal lives or how we should use our private, personal bodies. Not because we “hate” religion, but because we revere freedom.
I want to assure you very much that I don’t judge all Christians by the nasty actions of a few. Basically, as I’ve said before, I find it a shame that the word “Christian” gets applied both to true believers and those who just profess to believe because it gives them cover for their hate.
If there were more like him, I might still be a Catholic, grappling with the conflicts between doctrine and justice. And if there were more like him, the Church would not stand for people like Bill Donahue speaking in its name.
In fact if there were more like Father Cobos, maybe someone would have set Bill Donahue on a more Catholic path back when he was a child.
It was until now believed that nocturnally migrating songbirds, while venturing into the unfamiliar night sky for accomplishing their long, challenging trans-continental migrations, could at least release anti-predator vigilance thanks to the concealment of darkness. A new study by Spanish and Swiss scientists — published this week in PLoS ONE — shows that migration at night is not without predation risk for passerines.
Not every bloggers’ meetup has to be talking about blogging. We can also just get together and have fun. And so we did last night. A bunch of us went bowling.
On Wednesday nights they have great family rates. We got four lanes – one for kids, three for adults. My daughter tends to start out slow and get better and better as the time goes. In the end, she got some tens.
I am the opposite – my very first practice shot was a strike and I won the first game, but I get progressively more and more tired. Anton won the second game easily. In the end, my wrist and fingers were hurting so much, I was dropping the ball. And I am hurting all over today! You can see some more pictures here.
Last week, John Edwards put forward his healthcare plan which got pretty positive reviews – not an all-out single-payer system, but a good step in the right direction, pitting private and state providers in direct competition with each other (and since state can provide better care more efficiently for less money than any business, in the long run it should become popular enough to displace private health insurance from all but the richest people’s plans) which should reduce the cost of healthcare over time.
Unfortunately, the Right-wing attack on bloggers on the matter of science and medicine (not to mention the angry astronaut, Libby trial, Obama announcement, and the death of a Playboy playmate) reduced the amount of space given to the plan in the media.
I hope there will be more coverage of this week’s proposal. A few minutes ago, Edwards posted his comprehensive proposal to enact his plan to end the war in Iraq:
* Cap funding for the troops in Iraq at 100,000 troops to stop the surge and implement an immediate drawdown of 40-50,000 combat troops. Any troops beyond that level should be redeployed immediately.
* Prohibit funding to deploy any new troops to Iraq that do not meet real readiness standards and that have not been properly trained and equipped, so American tax dollars are used to train and equip our troops, instead of escalating the war.
* Make it clear that President Bush is conducting this war without authorization. The 2002 authorization did not give President Bush the power to use U.S. troops to police a civil war. President Bush exceeded his authority long ago, and now needs to end the war and ask Congress for new authority to manage the withdrawal of the U.S. military presence and to help Iraq achieve stability.
* Require a complete withdrawal of combat troops in Iraq in the next 12-18 months without leaving behind any permanent U.S. military bases in Iraq.
Considering the name of this blog, you may not be surprised that I am a sucker for clocks and watches. If I had more walls and more money, I’d collect them by dozens (hundreds?). Grow-a-Brain has been collecting links to sites showing all kinds of clocks.
I wish I could have something like this, this or this for the house and this for the pocket.
Tonight at 6pm, bloggers go bowling. Bring your lap-top – the bowling place has wifi.
Monday, some of us will go and get the NBC ascertainment.
Next week (2/21/2007) at 6pm free food and drinks for bloggers, courtesy of Duke University and its new DukeEngage initiative. Read more about it here and about the Wednesday happy hour here.
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males. These findings, published in this week’s Nature, suggest that female choice may be more widespread in nature than previously believed and that such strategies enable species to maintain genetic diversity.
