Last November, scientists announced they had revived a virus that had been dead for millions of years. The virus belongs to a special class that multiply by inserting their genetic code into the genome of their host cell. When the cell divides, it makes a new copy of the virus's genes along with its own DNA. Once it has installed itself in a genome, the virus can liberate itself from time to time, creating new copies. These copies can infect the same cell again, or wander out of the cell to infect another one. Some of these viruses, known as human endogenous retroviruses, may be harmless,…
Over at Aetiology, Tara Smith launched an interesting discussion by talking about why her heart doesn't automatically leap when a reporter wants to talk to her. That post was followed by a lot of scientists swearing up and down about the awful treatment they've experienced at the hands of reporters. Chris Mooney, a reporter, thinks the ranting is all misplaced, and wants us to understand that reporters who write about science are the best trained journalists of all. I thought I'd join the fray. I think, first off, that Chris is a bit off-base. He's not feeling the genuine pain being…
Today I jump sections at the New York Times. In the Week In Review, I take a look at the news of a bowhead whale that carried a harpoon tip for 115 years. It's a cool discovery, but 115 years is actually not extraordinarily long for a bowhead whale--or a rockeye rockfish. Both those animals can live over 200 years. In today's essay, I reflect on the evolution of old age (as well as the evolution of fleetingly short life spans). If you want to head for some scientific sources, check out the web site of Linda Partridge, a leading thinker on the evolution of aging at University College London.…
Nine years ago I had the opportunity to visit southern Sudan. With a few other reporters, I flew from Nairobi to Lokichokio in northern Kenya, where we prepared to cross the border. A man took our passports and told us he'd hold onto them till we got back. We climbed into another plane loaded with medical supplies and took off again, into a land that had been at war for 15 years. I found the place eerie in its quiet. We were far from the front lines, and so you could forget that there was a war going on, except for the occasional word of government planes in the air, potentially carrying…
Whoosh. A year has passed since I got my passport stamped with a scienceblogs.com visa. Thanks to all who have come this way and shared your thoughts. May the next year bring more of life's surprises.
For the past few years, Craig Venter, the human genome pioneer, has been trying to build an organism from scratch. While Venter is no shrinking wallflower (see, for example, a recent interview in Newsweek), he has been keeping his synthetic-life cards pretty close to his vest. I spoke to Venter in 2003, shortly after he announced the project, and he provided some basic details which I wrote up in a news article in the journal Science (I've archived it here). I was startled to find my article being cited in scientific papers about synthetic biology, but one scientist (Eugene Koonin of NIH)…
Okay--we're moving again. I await your comments (as usual, there will be small delay for moderation.) You'll have to make up for my appalling silence today as I work on (gasp) magazine articles. I know, I know, how very dead-tree of me....
Someone just emailed me to let me know she couldn't post a comment. For some reason that feature has shut itself down. I've been traveling, so it's taken me a while to start dealing with this. I'll let the Scienceblogs folks know of the problem, and let you know when it's resolved.
In about a month I'm heading to Colorado for the "Science and Media Summit" at the Aspen Science Center. The name may conjure up an image in your mind of a long table with diplomats from Science on one side and Media on the other, tensely negotiationg an end to some sort of bloodshed. As I understand it, though, the meeting should be much more amicable and interesting. The subtitle for the meeting is "Getting It Right: Science and the Media in the Emerging Media Landscape." Our mission will be to come up with a blueprint for good reporting on science in the age of blogs, YouTube, and…
A few months ago I got in my car and drove north until I reached a remarkable building filled with several million mice. At Jackson Laboratory in Bar Harbor, Maine, scientists are studying mice to understand many mysteries of genetics and medicine. But I was particularly curious about a project that they've only recently launched: an attempt to understand how many genes working together give rise to complex traits. When those complex traits go awry, the result may be a common disease such as heart disease, diabetes, or cancer. The article I wrote about what I learned, "Mendel's Mouse,"…
The paddlefish is a surreal giant, with a spatula-shaped nose that some scientists believe it uses to sense the electric fields of its prey, which it sucks up like a whale. You might not think of it as an animal that has much to offer in our quest to understand ourselves. But in fact, underneath the glaring differences, paddlefish and humans share some surprising similarities. And those similarities are precious clues to how our distant ancestors evolved hands and feet. Back 400 million years ago, our ancestors swam with fins. The descendants of those early fish split off into two main…
For those who don't know what I'm talking about, let me quickly recap (and then, at your leisure, read this post.) Last November, my article on the evolution of complex features came out in National Geographic. A few weeks later the article inspired a long but baseless attack from the Discovery Institute, an outfit that promotes intelligent design (a k a "the progeny of creationism"). The attack, authored by one Casey Luskin, came in three parts, climaxing in an argument for intelligent design that required me to wire my jaw back shut: "Was the Ford Pinto, with all its imperfections revealed…
Jennifer Jacquet at SB blog Shifting Baselines just returned from the Galapagos, where she got the feeling that blogging has not made much of an impact, even among the scientists at the research stations. It left her wondering if science blogging is mainly restricted to the so-called "First World"--i.e., affluent places such as the US, Europe, Australia, and Japan. If true, that would be a shame, since it is potentially such a powerful tool for getting scientific information, no matter where you are in the world. It's a fair question, but an answer really demands more data than one trip by…
Why don't I blog more? In part because I'm busy reading other blogs. I finally got around to adding some of my favorite science blogs outside the scienceblogs.com empire to the blogroll over on the left side. Allow me to take a moment to introduce you to them. The Anti-Toxo: A blog about every new paper or article on Toxoplasma, the resident parasite here at the Loom. If you want to understand our parasitic overlords, this is a must read. Center for Science Writings Blog. John Horgan, veteran science writer, now runs the Center for Science Writing at Stevens Institute of Technology. Lots of…
I just wanted to take a moment to reiterate my longstanding policy on comments. I reserve the right to delete comments that are slanderous, obscene, or glaringly off-topic. I also reserve the right to ban commenters who do not follow these rules even after being reminded of them. Anyone who accepts these simple rules is welcome to tell me why I am utterly wrong about the topic at hand, even if you think the world is six thousand years old. (And I am entitled to comment on why you are wrong, too.) But this is not the place for spam-like manifestos. Let the conversation resume.
Our culture wars make for strange ironies. The fight over the cervical cancer vaccine is a case in point. Yesterday news broke that a vaccine for cervical cancer might not be all it's cracked up to be. Cervical cancer is caused by a virus known as human papillomavirus. It infects epithelial cells in the skin and other surface layers of the body, including the vagina and throat. On rare occasion it causes its host cells to start replicating madly, creating growths that sometimes progress into full-blown tumors. It's a major menace: the American Cancer Society estimates that it causes 17…
There was a time when the publication of the entire sequence of a genome--any genome--was exciting news. I don't have any particular passion about Haemophilus influenzae, a microbe that can cause the flu various infections. But in 1997 it was the first species to have its genome sequenced. It became immensely fascinating, simply because we could now, for the first time, scan all of its genes. Now the global genome factory is cranking away so quickly--with over five hundred sequences published and over two thousand in the pipeline--that a new genome is not necessarily news. There has to be…
A bit of journalistic irony. Last week I groused that a new paper on methane from plants was getting very little attention in the press, despite the fact that it refutes a 2006 paper published in Nature that got lots of press. I wished aloud that the situation would be set right. Well, five days later, a few more sites have published the press release, but I've only seen one new piece of original reporting. It appears in the news section of today's issue of Nature. Hats off to Nature for making room for some uncomfortable news.
When you find yourself, as I did a few days ago, spending a morning watching the absurdly long phalluses of ducks being coaxed from their nether regions, you can find yourself wondering how your life ended up this way. Fortunately, there is a higher goal to such weirdness. The phalluses of ducks are just the tip of an evolutionary iceberg. The female ducks have their own kinkiness, too. It's all part of a fierce avian battle of the sexes. For the latest, see my article in tomorrow's New York Times. The paper on which it is based appears in the open-access journal PLOS One. Update 5/1, 11…
Here's a story that should be getting lots of press but apparently isn't: a new study indicates that plants don't release lots of methane gas. You may perhaps recall a lot of attention paid to methane from plants back in January 2006. A team of scientists (mostly from the Max Planck Institute for Nuclear Physics)reported in Nature that they had found evidence that plants release huge amounts of the gas--perhaps accounting for ten to thirty percent of all the methane found in the atmosphere. The result was big news for several reasons. It was a surprise just in terms of basic biology--…
