Life Through the Lens

netbros — Mon, 30 Mar 2009 11:00:11 -0800

Microscope Imaging Station opens a door to the wonder of the microscopic world and allows the layman to explore it. They seek to recreate some of the excitement and wonder that the earliest biological researchers found. Features include cells with potential as well as bad oogy. The microscopic Galleries are inhabited by zygotes and organelles.

Diffusion spectrum imaging

The Brain Unveiled: A new imaging method offers a spectacular view of neural structures. Diffusion spectrum imaging, developed by neuroscientist Van Wedeen at Massachusetts General Hospital, analyzes magnetic resonance imaging (MRI) data in new ways, letting scientists map the nerve fibers that carry information between cells.

What Lies Beneath

In the 13th century, thrifty monastic scribes erased an old Archimedes manuscript they had lying around and reused it. Thankfully, they didn't do a very thorough job. Ten years ago today, an anonymous American collector purchased the Archimedes Palimpsest, and has since funded the project to conserve, image, and study the manuscript, which contains several otherwise unknown works. Today, the Archimedes Palimpsest Project has released all its data and images under a Creative Commons license.

Shedding Light on Life

Frankieist — Sat, 19 Apr 2008 08:02:37 -0800

Light makes a comeback. “New technologies — more sophisticated imaging techniques, fluorescent molecules that act as beacons of light in the cell, and the computing power to gather and stitch together multiple images and create videos from high-powered microscopes — make it possible to harness one of light’s key advantages: gentleness. Unlike higher-resolution techniques, light microscopes can image biological structures without killing them or chemically fixing them. At Harvard, the resurgence of light microscopy is making it possible to see structures and events that have never before been seen in the context of living cells and organisms.” Also don't miss the video samples of “in vivo” imagining.

What is the relationship between the optical groove in a record or wax cylinder and sound, and how can we use this to recover analog recordings from the past? Dr. Carl Haber explains IRENE (.pdf; begin at slide 44 for audio samples).

HiRISE High-Res Images From Mars - Find the filing cabinet!

The HiRISE camera is one of eleven instruments on the Mars Reconnaissance Orbiter. Yesterday the first few images were downloaded from the MRO.

High Dynamic Range Imaging

High Dynamic Range Imaging: The dawn of a new era? In computer graphics and cinematography, high dynamic range imaging (HDRI for short) is a set of techniques that allow a far greater dynamic range of exposures than normal digital imaging techniques. The intention is to accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to the deepest shadows. quote from HDR Wikipedia page

Hot Sapphic Love (poem)

melmoth — Fri, 24 Jun 2005 03:28:05 -0800

New Sappho poem found. Combining a Cologne University fragment found in the cartonnage of an Egpytian mummy with a fragment from Oxyrhynchus has allowed the reconstruction of Sappho's fourth poem. The Oxyrhynchus papyri have been much in the news lately, what with the discovery of the earliest fragment of Revelations to give the number of the beast as 616 and the publication of several lines from Sophocles' lost tragedy The Progeny (scroll down). Infra-red imaging techniques may not be sexy, but Sappho sure is. After all, Plato said she was worthy of being considered not only as a poet but as a muse. Sappho herself is a palimpsest or a sort of cypher. We know next to nothing about her -- including whether she was lesbian or not. One thing's for sure: she almost certainly wasn't a schoolmistress.

Odd Spot on Titan Baffles Scientists

Diamornte — Wed, 25 May 2005 12:26:23 -0800

Unidentified Titan Object Saturn's moon Titan shows an unusual bright spot that has scientists mystified. The spot, approximately the size and shape of West Virginia, is just southeast of the bright region called Xanadu and is visible to multiple instruments on the Cassini spacecraft.

The Gigapxl Project has found a far less tedious method of producing stunning, ultra-high-definition images (up to 4,000 megapixels!) using specialized large-format equipment. (Another amazing image using multiple exposures can be found here.)

Digital Morphology, for when you really want to get up close and personal.

lychee — Mon, 28 Jul 2003 22:45:31 -0800

Digimorph, headed by University of Texas professor Timothy Rowe, is a collection of 2D and 3D cross-sectional images of everything from dinosaur skulls to fertilized emu eggs. Using an advanced X-ray Computed Tomographic scanner, researchers are able to capture minute details of a subject's internal structure. DigiMorph provides data on almost 300 species in the form of Quicktime animations, 3D movies, and stereolithography files which can be used (with the proper tools) to create your own 3D specimen.

If you've ever wondered exactly what's up with the stimulating hummingbird or the confounding platypus, now's the perfect time to take a more in-depth look.

This is an amazing photograph of what the world looks like at night, from a low orbit. Although this is found in a subdirectory of NASA's Astronomy Picture of the Day, I'm not sure how to get to this pic by surfing the site, nor do I have any information on what was used to do the photographing. The link was sent to me in an email.

Anybody know the details on this one?
