Time-Lapse Phonography

R. Luke Dubois' Billboard is a study in time-lapse phonography. Dubois digitally analyzed every #1 Billboard single from 1958 to 2005 and found a "spectral average" sound for each song. Every second of the piece represents one week in music history. The results are more interesting than you might think: compare the Beatles-dominated 1964 with the more processed, percussive sounds of 1997. Dubois has also created a time-lapse study of Oscar-winning movies. See also: "Chart Sweep" (scroll down to bottom of page). (via)

Climate Change

Scientists claim that cosmic rays from outer space play a far greater role in changing the Earth's climate than global warming experts previously thought. For a demonstration of how cosmic rays affect cloud formation, you can build a Cloud Chamber.

Space 199NOW

We could wait for NASA to build that permanent moon base they keep promising. Or we could just turn our apartments on earth into our own moon bases, space ships, or spy pads.

Converting Garbage into Energy

Mr Fusion - coming soon. Startech Environmental Corporation's "Plasma Converter" works like "the big bang in reverse," creating nothing out of something. With the ability to break down any type of material (other than nuclear waste) into component molecules and and actually generate energy in the process, we may be at the twilight of the landfill industry.

The dolphin with the artificial fin

An artificial fin has given a bottlenose dolphin a new lease on life. Fuji, a dolphin at Okinawa's Churaumi Aquarium, lost 75 percent of her flukes to an unknown disease. But a prosthetic fin developed by Bridgestone Corporation engineers has enabled Fuji to swim again in the aquarium's dolphin lagoon. Watch the BBC video report here. Read the aquarium's notes on the project and see photos of Fuji both during and after the disease's onset here.

2000 light years away

"I did not evolve from Turkana Boy or anything like it" says Bishop Boniface Adoyo of Nairobi Pentecostal Church, who is championing the 'hide-the-fossils' campaign to force the National Museums of Kenya to not discredit the Christian belief of a universe that is only a few thousand years old.

KSJTracker

Knight Science Journalism Tracker is a new-ish blog (project of a program at MIT and Charles Petit) that follows science writing and reporting in a very wide range of publications. It's a good way to learn about how science news is reported, and an efficient way to keep up with the news itself. [some recent examples]

White House reverses stance on existence of global warming

Energy Secretary Samuel Bodman has endorsed the recent IPCC report, reversing the White House stance on the existence of global warming. Bodman claims that the Bush administration has always accepted scientific studies pointing to man-made climate change, even as Henry Waxman, House oversight committee chair, has been holding hearings on the White House's misleading the public on global warming for the last six years; hearing documents. Bodman also rejects caps on CO2 emissions, claiming that the US is "a small contributor when you look at the rest of the world," when in fact it's the largest contributor worldwide (and has an even greater share of cumulative CO2 emissions). Previously: IPCC, Waxman.

"We're space explorers, and we need space!"

Where did you want to live when you grew up? If you're like me, you read Clarke's SF classic, Rendezvous with Rama (soon to be a major motion picture?). Donald E. Davis took what we dreamed about and illustrated it, for NASA. His depictions of O'Neill Cylinders, Stanford Tori, and Bernal Spheres are in the public domain (and make excellent desktop wallpaper).

Hubble ACS, We Hardly Knew You

Hubble's ACS Has Died. Hubble's Advanced Camera for Surveys has apparently gone into safe mode, with little hope of return. The ACS was installed in 2002, and added amazing upgrades to Hubble's imaging capabilities. Though its lifespan was only projected at five years, scientists had hoped it would hold out longer. Though a final shuttle servicing mission is scheduled for 2008, the mission objectives plate is already too full to consider its repair. Alas, more of those beautiful pictures (as well as extended research capabilities) will have to wait until the James Webb Space Telescope is launched in 2013.

Cancer

Cheap, safe drug kills most cancers. That's the good news. The bad news is that because there's no patent and it's so cheap to make, researchers may not be able to get funding from the private sector for further research since the treatment wouldn't make a profit. [Via Hullabaloo.]

Kinseyian mathematics, of a kind

The "Darwinian paradox" of homosexuality presents the conundrum of how a potential genetic basis for homosexual behavior could provide a survival benefit to offpsring and extend through generations, when sexual reproduction would seem to place strong selection pressure against such a "gene". Recently developed mathematical models (PDF) from researchers Sergey Gavrilets and William Rice not only show how a "gay gene" might proliferate within a population, but also provides testable hypotheses, including predictions of "widespread bisexuality" (subscription req'd).

Your boyfriend must have solved the problem for you.

"Ben Barres's work is much better than his sister's," one scientist remarked to another. The only problem is that Ben Barres and his “sister” Barbara Barres were the same person. An FTM transsexual offers a unique view of the impact of gender discrimination in science, having seen it from both sides. Despite the fact that recent studies have shown that a woman has to be 2.5 times as productive to be judged as scientifically competant as a man in the sciences, many still argue that there is actually a level playing field, a source of some frustration for many women in the field. (For a somewhat easier to read and referenced response to the Physics Today letters, check out Evalyn Gates’ reply at the end.)

Beyond Belief

Beyond Belief. Google Video of the complete proceedings of the conference Beyond Belief: Science, Reason, Religion and Survival, which took place on November 5-7, 2006 at the Salk Institute in La Jolla, California. (There are ten sessions, which average about two hours each.) Bios of the speakers who attended. A NYT article on the conference: "By the third day, the arguments were so heated that Dr. [Melvin] Konner was reminded of 'a den of vipers.' " Further conversation concerning the conference, in which Scott Atran writes, "I find it fascinating that among the brilliant scientists and philosophers at the conference, there was no convincing evidence presented that they know how to deal with the basic irrationality of human life and society other than to insist against all reason and evidence that things ought to be rational and evidence based. It makes me embarrassed to be a scientist and atheist."

The Secret Life of Machines and the amazing Tim Hunkin

All the episodes of The Secret Life of Machines are available online. Created by engineer, artist, tinkerer and cartoonist Tim Hunkin, the show took a look at the science and mechanics behind common household objects, with a bit of social history, homemade laboratory experiments, and downplayed humor. The series grew out of a long-running strip, which Hunkin has now offers as his own cartoon encyclopedia. You can also try some experiments of your own, marvel at the coin-operated contraptions he made for the Under the Pier Show in Suffolk (don't miss the film), and read his thoughts about his brief foray into the fine art world and his ruminations about how art and engineering mix.

The Lights in the Sky Are Stars

Universe Today is a news site for astronomy geeks. Don't miss its sibling, the Bad Astronomy Forum, which not only features examples of bad astronomy, but also discussions of space exploration and astrophotography. (If you like astrophotography, you're probably already aware of NASA's astronomy photo of the day.) But my favorite part of the whole site is the free astronomy eBook, What's Up 2007: 365 Days of Skywatching. If only it would only stop raining, maybe I'd grab some binoculars and go outside for some stargazing...

A day to be thankful for resublimated thiotimoline.

Think you get a lot done? Isaac Asimov (pronounced like "has, him, of" without the h's) , who would have turned 87 today, wrote or edited over 500 books, including science-fiction novels, introductions to organic chemistry (a field in which he held a professorship at B.U.) , indispensable anthologies of early science fiction, jokebooks, guides to Shakespeare, and collections of lively essays on science that have introduced thousands of people to the pleasures of thinking hard about the universe. He also found the time to write a few essays and write postcards to his fans. His story "Runaround" , from his 1950 collection I, Robot, is the only piece of fiction I know centered on the properties of a differential equation. His Foundation Trilogy was given a special Hugo award in 1966 as the best science fiction series of all time; a movie version, to be written by Jeff Vintar and directed by Shekhar Kapur, is currently in development.

“Allowing parents to select their children’s sexual orientation would further a parent’s freedom to raise the sort of children they want to raise.”

Cure for teh gay? I was relaxing in front of X-Men 3 when a friend mentioned that the United States "gay sheep" experiments were wrapping up (though not uneventfully), with considerable successes. Lesbian tennis champ Martina Navaratilova has been fighting to end the tests for some time, but it appears a "gay vaccine" for pregnant mothers may be inevitable. Meanwhile, the GOP's only gay congressman retires.

A Happy Family is a World's First

"There are few world firsts nowadays, but it may be one." - A quote used to describe triplets born to a woman with two wombs. Double uterus is an uncommon condition that is often undetected until a woman becomes pregnant. The outcome for such pregnancies is usually good, though posing a higher risk for breech positioning. The odds of triplets (twins in one womb, one fetus in the other) are 25 million to one.

Billions and Billions... of Blog Posts

Carl Sagan has a posse. Today marks the ten year anniversary of the passing of Carl Sagan, scientist and popularizer of science, and bloggers are planning to mark the day with posts about the man and how he's affected their lives. The initiative has the blessing of at least one member of the Sagan clan, and has already spawned a site where those without blogs of their own can post their thoughts online. Yes, Sagan could be prickly at times, and there might have been things he could have been more open about in his lifetime. But few scientists have done more to bring science to the public. These days, we could use another of him. Maybe two.

Medics face death in Libyan HIV case

Death by firing squad is imminent (timeline) for a Palestinian doctor and five Bulgarian nurses accused of infecting 426 girls and boys at the al-Fatah Hospital in Benghazi with HIV, after having the sentence lifted a year ago and sent to retrial. Libya stands accused of using the children as diplomatic pawns and torturing confessions out of the health workers. Nature has published a series of articles refuting the dubious evidence provided by Libyan researchers, which many think was concocted to cover up the poor hospital hygiene that likely caused the infections in the first place.
