Oldest preserved spider web found in amber

November 7, 2009 by skullsinthestars

This is one of those stories that just fills one with awe about the ancientness of life on earth.  Via The Great Orange Satan, I found this article in Wired about an amazing discovery:

The world’s oldest known spider web has been discovered on a beach in Sussex, England, trapped inside an ancient chunk of amber.

Scientists found the rare amber fossil in December, and have now confirmed that it contains remnants of spider silk spun roughly 140 million years ago by an ancestor of modern orb-weaving spiders. After slicing the amber into thin sections and examining each piece under a high-powered microscope, the researchers discovered that the ancient silk threads share several features common to modern spider webs, including droplets of sticky glue used to hold the web together and capture prey.

Spiders have been doing their web-spinning thing for at least 140 million years. That’s just amazing.

John Grant’s Bogus Science

November 6, 2009 by skullsinthestars

About two years ago, I had the pleasure of happening across and reading John Grant’s book Corrupted ScienceCorrupted Science deals with the systematic weakening, ignoring, and suppression of scientific reality for political purposes; examples include the disastrous Lysenkoism of Stalin’s Russia and the potentially catastrophic ignoring of evidence for man-made climate change.  Corrupted Science (CS) was Grant’s second book, following Discarded Science, which describes those scientific ideas that in the end turned out not to be true.

The other day, wandering through the exact same Barnes & Noble where I found CS two years ago, I found that Grant has a new book out exploring similar themes to his previous two, Bogus Science; or, Some People Really Believe These Things:

Bogus Science_fullsize

Where DS dealt with wrong science in the scientific community and CS dealt with wrong science in the political theater, BS focuses down and takes a look at individual kooks, crackpots, and frauds and their perversion of established science (and reality).

The book is very good; as a first statement I can highly recommend it.  There were also a few  aspects of it, however, that made me like it a little less than his previous book.

Horror writers on horror films, from Focus Features

November 3, 2009 by skullsinthestars

A few days ago, I got a nice email from FilminFocus.com, the film culture website of film company Focus Features (A Serious Man, Brokeback Mountain, Coraline).  For Halloween, they asked five horror writers to each list their five favorite horror movies.  Some of the names I’m familiar with — Kim Newman, Joe R. Lansdale, Tananarive Due — and others are new to me, but their choices are all interesting, even though there are some that I wouldn’t necessarily agree with (Carnival of Souls?  Really?).

You can read the list here.

Though I’m not a professional horror author (yet), I thought I’d chime in with my own set of movies that disturb me!   This list is by no means complete — after all, it’s only five — but it is indicative of what unsettles me…

Renaissance Mathematicus on the blogroll!

November 3, 2009 by skullsinthestars

Just a short note that I’ve added Renaissance Mathematicus to the blogroll, a long overdue addition!  For those readers here who like the history of science, I can highly recommend thonyc’s blog, if you haven’t been reading it already!  A mission statement about the scope and contents can be read here.

12 days until The Giant’s Shoulders #17!

November 3, 2009 by skullsinthestars

There’s 12 days left until the deadline for The Giant’s Shoulders #17!  It will be held at The Primate Diaries, and entries can be submitted through blogcarnival.com or directly to the host blog, as usual!

The movie 2012… stoopid before it even comes out

November 2, 2009 by skullsinthestars

You know, I’m not in principle against a film based on the premise that the world will end in 2012 as prophesized by the ancient Mayans, even though the idea is complete bunk.  What does bug me is that the film is by Roland Emmerich, and looks to be another noisy, incoherent mess heavy on special effects and almost bereft of plot or character development.  (See Godzilla, The Day After Tomorrow, 10,000 BC, etc.)

I had to laugh, though, when I saw this trailer on television the other day.   The text of the trailer declares,

The Mayans warned us

We should have listened

Waitaminit — the film is, in essence, about the end of the world, involving the destruction of pretty much everything on the planet.  How would listening to the Mayans actually help at all in such a circumstance?  How are we supposed to prepare for the end of the world, “duck and cover”?  Hide under the kitchen table?  Build enough spaceships to fly everyone to the moon?

This sort of incoherent trailer does not bode well for the film, in my opinion.  Then again, has there ever been a film about global catastrophe that has been any good?  Looking through the recent list of choices — Armageddon, The Day After Tomorrow, Deep Impact — I can’t say there are any that are particularly memorable.  Really, there have been so many movies involving mass destruction in the past few years that I’m totally desensitized to it.

ResearchBlogging editor’s selections: Replicating historical sites, dating the universe, zombies, vampires and werewolves, oh my!

November 2, 2009 by skullsinthestars
  • Replication. teofilo at Gambler’s House talks about an interesting proposal for preserving delicate historical sites: build exact replicas of them!  Replicas of smaller artifacts could also be used to resolve disputes of ownership amongst various countries.
  • Universe lets age clue slip. Greg Laden, at the eponymous Greg Laden’s blog, describes recent astronomical observation that extends the known age of the  universe.  He manages to explain the discovery in a very terrestrial context!
  • Blood and brains — can vampires survive a zombie apocalypse? We all know that the odds of humans surviving a zombie apocalypse are pretty bleak, but what about vampires?  Southern Fried Scientist over at Southern Fried Science describes some mathematical modeling that was done to look at the survivability of the #1 undead predator during an outbreak of the #2 predator.
  • Werewolves of London, Ontario. Neurocritic over at The Neurocritic talks a bit about another classic monster — the werewolf — and the psychological basis of lycanthropy.  Stories of people believing that they’re animals go back a long way…

Finally, as long as we’re on the subject of monsters, and Halloween is so recently behind us, let me point to my own contribution: Boo! The optics behind “ghost” imaging.

Check back next Monday for more “miscellaneous” highlights!

Boo! The optics behind “ghost” imaging

October 31, 2009 by skullsinthestars

ResearchBlogging.orgHalloween seemed like the perfect time to talk about an unconventional sort of optical imaging, referred to as “ghost” imaging.  I should point out at the beginning, however, that I’m not talking about this sort of ghost imaging:

tulipstaircaseghost

Don’t get too disappointed, however!  Ghost imaging is in fact a fascinating and relatively new technique in which a detector can produce an image of an object that it cannot see!  The physics behind this effect is somewhat subtle, and resulted in at least one minor controversy since its introduction.  Let’s take a look at it…

Halloween treats 2009

October 30, 2009 by skullsinthestars

It’s time again for my yearly dose of Halloween chills, courtesy of some classic horror stories!  The 2007 edition can be found here, and the 2008 edition can be found here.  Have a happy Halloween!

The Willows, Algernon Blackwood.  This tale is long, but is one of the absolute classics in the genre of “cosmic horror”, and one of the major inspirations for H.P. Lovecraft’s work.  Two men, canoeing down an isolated stretch of the Danube, escape rising flood waters by sheltering on a small island on the river.  They soon realize, though, that they have stumbled within reach of beings from outside of time and space — beings that threaten their lives, sanity and souls.

Number 13, M.R. James.  A visitor to Viborg decides to lodge at the Golden Lion, and chooses to stay in room 12, which has a lovely view of the street.  At night, however, his room seems smaller, and on the building across the street he can see shadows of the occupants of room 13 — a room which doesn’t exist during the day…

The Shadows on the Wall, Mary Wilkins Freeman.  A story of domestic horror.  A family struggling to recover from a terrible tragedy finds their efforts hindered, and haunted, by the presence of a shadow on the wall without a source.

Mysterious Maisie, Wirt Gerrare.  A very unsettling story about a woman who takes a job as a maid but finds herself a prisoner of a cult-like group that have unpleasant plans for her.  These plans involve a mysterious visitor to the home who seems not quite human… (Only available through archive.org; you can download the story collection or read it online at the link.)

The People of the Pit, A. Merritt. Explorers of the northern Alaskan wilderness happen across a man who has crawled until his hands are little more than ragged stumps!  He tells a story of a deep pit, a lost city within it… and the people of the pit.

The “curse” of success in science

October 29, 2009 by skullsinthestars

(This post may seem like boasting just as much as it seems like complaining, for which I apologize in advance.)

Those who are regular readers of this blog may have noticed that things have been a little quiet again for the past couple of weeks.  It turns out that I’ve been almost entirely buried under a mass of bureaucratic tasks, which I’ve managed to dig myself out from under, at least for a while.

As a graduate student and post-doc, I always marveled at how senior researchers would burden themselves with a large number of bureaucratic tasks, such as journal editing, academic committees, article reviewing, proposal reviewing, and conference organizing.  I confidently reassured myself that I would never allow such tasks to bog me down and take away from my true academic love, namely research.

What I hadn’t counted on is the fact that, as I’ve become more established and well-known in my field, I’ve made friends with lots of people who are journal editors, conference planners, and book publishers.  I end up refereeing some 20 papers a year for journals, simply because I’m friends with a large number of editors.  This year, I’ve taken a rather high-up role in the organizing of a major optics conference, primarily because two friends asked me if I could help them out.

I can’t complain too much, because it is quite flattering to be asked to help with these things, and it is quite interesting to see how things work behind the scenes at journals, conferences and publishing houses.

It may be a little too enlightening, however.  When I was younger, there were a number of conferences I attended where I thought to myself, “Who organized this mess?”  Today I realize that it was probably someone like me: a person hesitantly agreeing to accept an organizing role and now scrambling to get the pieces to fit together as a coherent whole.

The situation is analogous to growing older in general.  As children, we tend not to worry about things too much because the “grown-ups” are in charge and will take care of everything.  Then, inevitably, you suddenly realize one day that you are now the grown-up — and nobody gave you an instruction manual for the job!
