A new study published in the Proceedings of the National Academy of Sciences finds that a global nuclear war would lead to a surge in democracy.

(Note though that the study was conducted by "Belgians", so assume some devious angle is involved.)

Sufferin' Sirenia! Florida's Homosassa Springs Wildlife State Park wants to build a monorail for their manatees:

Although the state plans improvements to make the manatee treatment pools work better for the animals, [park manager Art] Yerian's wish list includes a $100,000 monorail system that would allow park officials to slip manatees into slings, hoist them with pulleys and use the rails to move them from the spring run to the holding or treatment pools.

Aren't these gentle creatures endangered enough without exposing them to the risk of collisions, spontaneous combustions, or abductions? Even worse, the manatee's closest relative is the elephant -- do park officials not know how poorly elephants take to monorails?

I propose a better, more manatee-friendly, less manatee-cidal, way to get them from pool to pool: a Pneumatic Manatee Distribution System. Given their fusiform shape, you wouldn't even need pods; just stuff them in the tube, close the hatch, and press Send.

A paper to be published on red, cell-like particles that rained over India in 2001 has rekindled interest in panspermia -- the hypothesis that life on earth was seeded from space. The paper's researchers also wrote two unpublished papers on the subject in 2003 that made stronger panspermian claims (#1 & #2).

I'm repeating this story and links swiped from Slashdot only so I can add this quote from Lord Kelvin giving the reasoning behind the concept:

Every year thousands, probably millions, of fragments of solid matter fall upon the Earth—whence came these fragments? What is the previous history of any one of them? Was it created in the beginning of time an amorphous mass? This idea is so unacceptable that, tacitly or explicitly, all men reject it. It is often assumed that all, and it is certain that some, meteoric stones are fragments which had been broken off from greater masses and launched free into space. It is as sure that collisions must occur between great masses moving through space as it is that ships, steered without intelligence directed to prevent collision, could not cross and recross the Atlantic for thousands of years with immunity from collisions. When two great masses come into collision in space it is certain that a large part of each is melted; but it seems also quite certain that in many cases a large quantity of debris must be shot forth in all directions, much of which may have experienced no greater violence than individual pieces of rock experience in a land-slip or in blasting by gunpowder. Should the time when this earth comes into collision with another body, comparable in dimensions to itself, be when it is still clothed as at present with vegetation, many great and small fragments carrying seed and living plants and animals would undoubtedly be scattered through space. Hence and because we all confidently believe that there are at present, and have been from time immemorial, many worlds of life besides our own, we must regard it as probable in the highest degree that there are countless seed-bearing meteoric stones moving about through space. If at the present instant no life existed upon this earth, one such stone falling upon it might, by what we blindly call natural causes, lead to its becoming covered with vegetation. I am fully conscious of the many scientific objections which may be urged against this hypothesis; but I believe them to be all answerable. I have already taxed your patience too severely to allow me to think of discussing any of them on the present occasion. The hypothesis that life originated on this earth through moss-grown fragments from the ruins of another world may seem wild and visionary; all I maintain is that it is not unscientific.

A recent article on making a macro lens using a Pringles can led me to a fortunate discovery that may be of use, or at least give ideas, to someone else, so I'll pass it along...

It turns out that a lens hood accessory I had lying around from a circa-1960s Pentax SLR can be jury-rigged to allow the use of that camera's filters and lenses with my Sony Mavica CD500 digicam (which otherwise would need a $35 adaptor from Sony to accept accessories). The hood, intended to keep stray light out of lenses, is just a metal tube with threading on one end that screws into the filter threads on the lenses (not all hoods use threading, though -- I also have one from another camera that uses a compression fitting.)

By lining the inside with a 3cm wide strip of felt cut to the inner diameter, the hood can be slid, thread-end pointing out, snugly onto the telescoping-lens base of the Mavica. It's just the right length to allow clearance for the moving lens, which can now be enclosed and protected with a filter.

Besides filters, lenses can also be screwed onto the hood's threads, albeit backwards. What use is a backwards lens? Macro photography! Reversing a standard lens turns it into a serviceable macro lens. (For those with the same camera: Turn the macro mode on and zoom all the way in. Do not use the "Conversion Lens" mode.) Wide angle lenses give even better magnification, but will have greater vignetting. Oh, and try a telephoto lens if you feel burdened by too many megapixels.

Anyway, here's some pics taken with my newly-discovered macro lens:
