Volcano Profile: Erta Ale

The latest in my Volcano Profiles series, this one on Erta Ale in Ethiopia. The summit crater at Erta Ale in 1994 Location: The Afar region of Ethiopia. Height: 613 m / 2,011 feet Tectonic setting: Erta Ale (meaning "smoking mountain") is part of the East African Rift, where the African Continent is tearing apart along a seam that runs from the Red Sea/Gulf of Aden (two other arms of the rift themselves) south through eastern Africa. Many of the large lakes of eastern Africa such as Lakes Albert, Tanganyika, Nyasa and Kariba fill rift valleys created by the cracking of the continental plate…

Japan nuke news 18: Reactor facilities smoke, sputter. Fission continues?

Claims are being made that the situation at Fukushima is starting to improve, but there is no actual evidence of this. We probably (but not certainly) passed the point where nuclear fuel is likely to accumulate in such a way as to cause a major fission event or explosion, but there is still sufficient heat to cause, apparently, water to split into hydrogen and oxygen, or at least, there is concern of this possibility. (Hydrogen explosions have already occurred here early on in the crisis, and there is concern that this may happen again.) All of the basic safety systems are still not working…

The Physics of why the e-Cat's Cold Fusion Claims Collapse

"Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy." -Carl Sagan (This post is coauthored by Dr. Peter Thieberger, Senior Physicist at Brookhaven National Laboratory.) A cheap, clean, efficient and virtually limitless source of energy would be just what our world needs right about now. The cheap sources -- coal, oil, and gas -- are dirty, destructive, and limited, while the clean sources -- wind and solar -- are expensive and…

Comments of the Week #151: from lost information to the atmosphere of Mars

“A theory is a supposition which we hope to be true, a hypothesis is a supposition which we expect to be useful; fictions belong to the realm of art; if made to intrude elsewhere, they become either make-believes or mistakes.” -G. Johnstone Stoney It's been another exciting week here at Starts With A Bang! This coming Thursday, I'll be speaking at Jacksonville University in Florida; if you're around that area come and say hello! Before we get any further, I'm pleased to announce that thanks to two very generous new Patreon donations from Ryan Schultz and Samir Kumar (shout-out!), we've now…

Comments of the Week #132: from dark comets to alien searches

"Ships that could circumnavigate the galaxy in a few years, and count every cell in your body from light-years off, but he wasn't able to go back one miserable day and alter one tiny, stupid, idiotic, shameful decision..." -Iain Banks And while we can't travel back in time at all to change the actions or events of the past, our incomplete knowledge of the past can always be improved as we move forward. This month's Starts With A Bang podcast is one of the most fun of all, as we cover how we went from mere lower limit estimates of how many galaxies are in the Universe to the first true,…

Democracy Now! - Greenhouse Emissions Rising at Unexpected Rate

Today's DemocracyNow! has a segment with Chris Field, a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change and other guest discussing worsening outlooks of future warming and increased lobbying efforts from the fossil fuel industry. We speak to Chris Field, a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change, about his warning that the amount of greenhouse gases in the atmosphere is rising more rapidly than expected in recent years. Field says the current trajectory of climate change is now much worse than the IPCC had…

Friday Fun: 31 Days of Halloween!

The science fiction news site blastr has a very entertaining series going for the month of October, 31 Days of Halloween. As you would imagine, every day this month they are featuring a post about Halloween. And fortunately the topics range from the bizarre to the ridiculous all the way to the barely safe for work. Here's a sampling: 33 scary stories you can read RIGHT NOW from great horror writers Vader, Spock, Spidey and 26 other sci-fi icons as rotting zombies 18 LEGO creations so unnerving they could give you nightmares Zombies and vampires rule in 14 horrific Halloween board games What…

The Buzz 3/24: What If the Montreal Protocol Were Never Signed?

If climatologists saved the world and nobody experienced the alternative, would it make an impact? New research conducted at NASA's Goddard Space Flight Center suggests that it should. The Center used cutting-edge computer modeling technologies to address the question: "What if the Montreal Protocol that regulated the emission of ozone-depleting chlorofluorocarbons (CFCs) had not been signed?" The answer, it turns out, is catastrophe. The findings are a welcome change from the usual "doom and gloom" tune that frequently accompanies environmental reports, and gives evidence that intervention…

Prehistoric Dental Hygiene

Our Neanderthal ancestors probably cleaned their teeth, Spanish newspaper El Pais reported recently. Spanish paleontologists recently uncovered two, 63,400-year-old tooth fossils near Madrid. The molars, found in near-perfect condition, once resided in the jaw of an approximately 30-year-old Neanderthal. It's been 25 years since another human specimen has been unearthed from that region. But even more exciting, head researcher Juan Luis Asuarga told El Pais, is that the teeth showed grooves that were likely formed by some kind of pointed object—presumably, a small stick used for cleaning…

Tet Zoo picture of the day # 12

When most people (and that includes palaeontologists and dinosaur specialists) think of Brachiosaurus, they think of the east African taxon B. brancai, named by Werner Janensch in 1914. But they shouldn't: the 'real' Brachiosaurus is B. altithorax from the Morrison Formation of Colorado [later reported from Utah, Wyoming and Oklahoma], named by Elmer Riggs in 1903. The two species are actually quite different, leading Greg Paul to coin a new name - Giraffatitan - for the African taxon. This photo, kindly provided by Dr Matt Wedel (aka Dr Vector), shows the mounted B. altithorax skeleton that…

Dinosaurs are coming to Raleigh!

OK, I live here, yet I had to learn from Brian that the AMNH dinosaur exhibit is coming to the North Carolina Museum of Natural Sciences in downtown Raleigh. The exhibit will be open from October 26, 2007 till March 2, 2008 and I will make sure to go and see it while it is in town (and take pictures if they'll let me and then blog about it). If you come from out of town to see the exhibit, don't forget to also see the dinos that are on permanent display at the Museum: the Acrocanthosaurus (the only skeleton of its kind displayed anywhere - and it is not a cast either but the real thing) and…

The Fly Buzz Continues

The Fly Spontaneous Behavior paper is generating quite a lot of buzz. Bjorn has collected some of the best blogospheric responses, including these from Mark Chu-Carroll, Mark Hoofnagle and Kate. He also got Slashdotted - of course, whoever posted that on Slashdot failed to a) link to the paper, b) link to the press release and c) link to Bjorn's blog. Instead, a little blurb from one of the worst media articles from MSNBC is the only link. Those got linked later in the comments, so I hope Bjorn enjoys the traffic (it will go away tomorrow never to come back again). Bjorn has also posted…

Where Are You From?

Reader demographics based on 100 visitors. While I take a brief break from writing this week's issue of Birds in the News, I want to mention that I am proud to say that once again, nearly half of my visitors are from outside of the United States. Not that I have anything against Americans, because I do not, but it pleases me to think that the topics that I write about have an international appeal. Since I have your attention, I am curious to know where you are from? Is this your first visit to Scientific Life or to ScienceBlogs? How did you find ScienceBlogs/Scientific Life? What do you…

Another Gold Foil Figure Die from Zealand

Another one of the rare production dies for 6/7/8th century gold foil figures has come to light, again on Zealand! This is an unusual design depicting a lady from the front. She's wearing a long dress, a cloak and two bead strings. She seems to be cupping her hands around a ring at her abdomen. The rings on her dress hem are quite odd. Parallels to the general motif and design are known from Eketorp on Öland (a foil) and Sättuna in Östergötland (a die). Congratulations to detectorist Hans, and thanks for doing other folks with an interest in the past a big favour! Update 4 Feb: Aard regular…

TVs and computers breeding generation of 'screen kids'?

Sez the Grauniad. So far so dull. More interesting was TVs and computers are the "electronic babysitters" for a generation of children who are losing out on family life and becoming more materialistic, a report says today. The study paints a picture of a breed of "screen kids" who are spending more and more time watching TV and surfing the net in their bedrooms, unsupervised by adults. The Watching, Wanting and Wellbeing report from the National Consumer Council found nearly half the children from better-off families surveyed had televisions in their bedrooms, compared with 97% of the nine-…

074/366: Gotham City

This is a pure document-my-day shot, not one of my random attempts at artsy effects. One of The Pip's birthday presents was a big vinyl wall decal from Chic Walls, a gift from Aunt Erin in California. These are a little complicated to install, and SteelyKid being sick messed up the whole week, but I finally got around to putting it up Friday: The Pip's new Gotham City wall decal. So, our superhero-crazy Little Dude now has Gotham City on his wall. He's all fired up about this. And that's it from Friday; I'm still fighting a cold of my own, so between this and some video shooting for a…

GP for the masses

My colleague Nic McPhee (with a couple of other people) is an author of a new book, A Field Guide to Genetic Programming — I think I'm going to have to read it. Genetic programming (GP) is a systematic, domain-independent method for getting computers to solve problems automatically starting from a high-level statement of what needs to be done. Using ideas from natural evolution, GP starts from an ooze of random computer programs, and progressively refines them through processes of mutation and sexual recombination, until high-fitness solutions emerge. All this without the user having to know…

Metal Detectorist Tattoo #6 - Kvanli

Detectorist John Kvanli is the chairman of Rygene detektorklubb and one of Norway's most prominent proponents of collaboration between amateurs and professionals in field archaeology. Of course he has a tattoo! It's an Urnes brooch from c. AD 1100, in the final exquisite Christian style of Scandinavian animal art. John tells me he has found several fragments of these fragile objects, but the one inked onto his upper right arm is a settlement excavation find from Lindholm Høje, across the fjord from Aalborg in northern Jutland. The needlework was done by the Martin Tattoo Studio in Bangkok,…

Baby Blogging Backlog

I've been really bad about documenting The Pip's growth here. The annoying thing is, I've actually taken pictures of him over the last couple of weeks, but I've been too busy to edit and post them. If there's one thing transcontinental flights are good for, though, it's providing you with time to do stuff like this. So, here are some photos of The Pip from the last few weeks, starting with one of this first shots of him smiling: This is a couple of weeks old, already, and he's much more expressive now. Here's an Appa-for-scale shot from the same day: And here's an Appa-for-scale shot from…

Achilles and Hector Cannot Both Walk into the Sunset Alive

Bummer news from Making Light this morning: one of my favorite authors, John M. Ford, has died. That's a shitty way to start the week. The post title is from his poem Troy: The Movie, which does not involve Brad Pitt. Also well worth reading is his September 11th memorial poem 110 Stories, which I had taped up outside my office for a long time. His NESFA collection, From the End of the Twentieth Century is full of good stuff, as is the more recent Heast of Fusion, and Growing Up Weightless may be my favorite coming-of-age SF story ever. He was also an occasional poster to Making Light, and an…

Why does your voice sound different than you expect it to sound?

... like, when you hear it on playback from a tape recorder. Sound can reach the inner ear by way of two separate paths, and those paths in turn affect what we perceive. Air-conducted sound is transmitted from the surrounding environment through the external auditory canal, eardrum and middle ear to the cochlea, the fluid-filled spiral in the inner ear. Bone-conducted sound reaches the cochlea directly through the tissues of the head. When you speak, sound energy spreads in the air around you and reaches your cochlea through your external ear by air conduction. Sound also travels from your…

OVER 1 MILLION!

This past Tuesday a troupe of SciBlog readers met up in OKC for pizza, beer, and cookies!! Ill leave it to readers to out themselves if they want (or email me to anonymize you!), but I had to put up a funny pic of Logan, my partner-in-crime from Dembskis infamous OU visit: And a pic of the good sports at 'the other table' (we didnt have the room I thought we had reserved, so the group got broken up *sad* ), plus a crazy ranting atheist: Some nice OESE folks sent home some pizza for poor Arnie. It was amazing how fast he went from 'poor baby who cant get up from bed' to '…

INCONVENIENT TRUTH'S PROFITS LEVEL OFF: Opens in 73 More Theaters, But Weekend Gross Falls Short of Previous Two Weekend's Earnings

It appears that while audiences continue to go see Inconvenient Truth, some of the excitement has worn off. According to BoxOffice Mojo, the film opened in 73 more theaters this weekend, bringing its total to 587, still a tiny number compared to the 3000 screens that blockbusters run on. Across these theaters, the film earned 1.597 million over the weekend, down from the 2.016 million the week before, and the 1.911 million from two weeks back. So far, the film has earned a total of 12.359 million, ranking it fifth all-time among documentaries, just behind Madonna's Truth or Dare Meanwhile…

Bionic arm in the news

Beebs on Claudia Mitchell, the second person to be fitted with the bionic arm. Cool video there. What is a bionic arm? From the RIC page: The "Bionic Arm," or myoelectric arm, is driven using electrical signals from the muscles of the chest, now activated by the user's own thought-generated nerve impulses. These impulses are sensed, via surface electrodes, from the pectoral muscle and carried through to the mechanical arm, causing the arm to move. Very impressive. We can now replace hearts, eyes, ears and limbs. The list keeps growing. I personally would like to see the day when we can…

Debris Threat to International Space Station; Crew Evacuating to Soyuz as Precaution

A moderately large piece of space debris has only recently been identified as a threat to the International Space Station - too recently for the station to be moved out of the way. The object is now projected to pass close enough to the ISS to put it into the high threat category. As a result, the astronauts onboard the ISS will be moving from the station into the Soyuz escape capsule as a safety precaution. The closest approach is predicted to occur at 11:39 CDT - about 20 minutes from now. The crew is currently preparing to board the Soyuz. If all goes well, they'll be in the Soyuz from…

New Feminist Blog and Nifty Database

There's a great post over at the blog Women in Science on a resource, the Harvard Open Collections Program Women Working 1800-1930. ...a great digital database of books, photos, diaries, and trade catalogs. It covers all kinds of work, from unpaid household labor to lawyers and politicians. And, of course, scientists. Go read the post for a sampling of goodies from the collection. Many thanks to Women in Science for pointing us all to this rich archive! Also, from the WMST-L listserv, I learned of a new Feminist Philosophers blog . This is not a philosophy of science blog, it's subject…

Bits and pieces

I'm away from what serves as my computer these days for a while - off to Sydney to find a place to live. Also, the Seed Masters (whom I for one welcome) are upgrading Moveable Type from 3 to 4, so we can't blog for a few days anyway. But I would like to announce that my paper with Gareth J. Nelson on a possible precursor to punctuated equilibrium and the biological species concept, Pierre Trémaux, has been published in the journal History and Philosophy of the Life Sciences. The full details are: Wilkins, John S., and Gareth J. Nelson. 2008. Trémaux on species: A theory of allopatric…

Casual Friday postponed til Saturday

I'm not quite finished analyzing the data from last week's Casual Friday's study and I've got some personal business to attend to this afternoon, so I'm going to have to postpone my writeup of the results until tomorrow. Sorry! One item of interest from today's results: Some commenters this morning wanted to know what percentage of our readers are Americans. Here's the breakdown based on this study (however I think it's quite possible that non-Americans weren't as interested in this study as usual): So 78 percent of our readers are U.S. Citizens living in the U.S., and just 12 percent are…

Please Give to Cyclone Relief!

The Intersection just got an email from Oxfam America, asking for our help getting the word out about the urgent need to help cyclone survivors in Myanmar. To quote in brief: "In the aftermath of Cyclone Nargis - which struck Myanmar on May 3, washing away entire communities - conditions remain dire for millions of people. Food and water shortages are rapidly increasing risk of disease, and more bad weather threatens those who have survived....With death tolls climbing - the latest count puts deaths above 120,000, with 500,000 homeless - we are urgently looking for support from outlets like…

Early color circles: Newton for artists

C.B., circa 1708: "These color circles, from a 1708 edition, are the earliest published examples of Newton-style color circles in an artist's manual." Moses Harris, 1766: "Mimicking the spread of light from a source, Harris places the pure colors at the center of his circle and the lightest at the outer edge." Schiffermuller, 1772: "Like many others with the same goals, he assumed that there is a knowable natural order to color, one that would confirm the relationship among all forms of knowledge." More quotes and images from Sarah Lowengard's e-book The Creation of Color in 18th Century…

Newly Discovered Antarctic Marine Life Attacks and Consumes Researchers

Researchers from New Zealand's National Institute of Water and Atmospheric Research have discovered hundreds of potentially new species. Part of the International Polar Year survey program, the critters were hauled up from the briny depths around Antarctica. Among the 30,000 once living beings now in formaldehyde are huge sea spiders, jellyfish with 12-foot tentacles, enormous sea snails and starfish. The expedition was also made into a documentary entitled DeepStar Six... Giant Macroptychaster sea star measuring 60 cm across Antarctic toothfish (1.81 m long, 57 kg) CR McClain from Deep…

Recommended reads on women in math, science, engineering.

They're both by men, but sometimes it happens that way. Mark Chu-Carroll ridicules Vox Day's ridiculous claim that women are too dumb to do long division, let alone program computers. While Day's claim was silly from the get-go, Mark's take-down in really nice. A friend from the three-dimensional world (specifically math camp), Jonathan Kulick, who cannot hide from the blogosphere even in Tbilisi, examines claims that women are underrepresented in science for reasons other than bias. Will it surprise you to hear that Christina Hoff Sommers may be dismissing research she doesn't like out of…

Bastille Day sprog art.

Not that the art has anything to do with Bastille Day, but it seemed like as good an occasion as any to share some more of their work. And, for the record, if art classes somehow lead the Free-Ride offspring to adopt an all-black wardrobe, they are bloody well going to find themselves reading Sartre. In our house, moody black-clad young people are philosophers! From the younger Free-Ride offspring: I'm told this is a water buffalo striding to the water hole by moonlight. My sense, from the drawing, is that a water buffalo could sneak up on you on a dark night. From the elder Free-Ride…

AAP reports from the future

This story from the Australian Associated Press contains the usual scare-mongering from Ian Plimer: AAP November 19, 2009 01:36pm Australia will go broke and become the laughing stock of the world if politicians ignore basic science on climate change, a leading global warming sceptic says. But there is one intriguing detail: Prof Plimer's comments came as he delivered the annual Essington Lewis Memorial Lecture in honour of a former chief executive and chairman of BHP. And that lecture won't be delivered until 6pm today (Nov 19). I think it is awesome that the AAP can report from the future…

Our Sex Columnist Featured by ELLE Magazine

E. Jean Carroll, the infamous advice columnist for ELLE magazine, picked 40 sex columnists from student newspapers across the country, and our own Amanda Baldwin was one of them. Carroll set all 40 columnists up on her website, giving them space to post their columns for the nation to read. To see Amanda's contributions, select her name from the drop down list (one of the first on the list; the site is javascripted, so there's no direct link). I feel like a proud parent. Amanda has gotten so much crap over the past couple years as our sex columnist, from English professors giving her a hard…

Woman grows a "scrotum", loses husband

Chinese Necklace by Inextremiss (Flickr)   From the Annals of the Weird, or more precisely Proceedings in Obstetrics and Gynecology, comes the story of a 21-year-old woman from rural India presenting a benign vulvar tumour resembling a "soft, pedunculated mass, with a wrinkled surface dangling from her left labia majus" about the size of a tennis ball. She had been abandoned by her husband, proving he was insecure about the fact his wife had bigger balls than him.  Happily, after a visit to the doctors, the five year old growth was removed with "excellent cosmetic result", leading to smiles…

mmmmmm.....tasty......Neanderthal mmmm.....

Well it seems that Neanderthals may have had a taste for.. well... other Neanderthals. Neanderthals suffered periods of starvation and may have supplemented their diet through cannibalism, according to a study of remains from northwest Spain. Paleobiologists studied samples from eight 43,000-year-old Neanderthal skeletons excavated from an underground cave in El Sidrón, Spain since 2000. The study sheds light on how Neanderthals lived before the arrival of modern humans in Europe. Researchers found cut marks and evidence that bones had been torn apart, which they say could indicate…

Carry a gun = you get shot more often

In a first-of its-kind study, epidemiologists at the University of Pennsylvania School of Medicine found that, on average, guns did not protect those who possessed them from being shot in an assault. The study estimated that people with a gun were 4.5 times more likely to be shot in an assault than those not possessing a gun. source From the abstract of the paper: Objectives. We investigated the possible relationship between being shot in an assault and possession of a gun at the time. Methods. We enrolled 677 case participants that had been shot in an assault and 684 population-based…

Mobile Phone Ingenuity in Africa

This post from one of my favorite blogs, AfriGadget, highlights interesting ways that Africans are modifying cell phones for their unique technological needs. It is based on the author's (Erik Hersman) conversation with Jan Chipchase, a design and usability ethnographer for Nokia, who travels around the world to explore how mobile phones are used worldwide and then reports his findings back to Nokia's design team. He explains: While exploring in Africa [Jan] found a booming market of hackers and mobile phone mechanics who are doing all kinds of interesting things such as creating new mobile…
