Piss up ?

Taking a (the) piss. Handy hints from MoFi.This takes the cake. *efficiently urination for males: first of all, learn to urinate while in a seated position. It is more relaxing, less spray intensive, and the spreading of the loins allows for a relatively thorough emptying of the bladder. Spread legs slightly for optimal effect.(There's a lot mi)

Human Variety

The Nature of Normal Human Variety A talk with Dr. Armand Leroi (his website). "Almost uniquely among modern scientific problems [the problem of normal human variety] is a problem that we can apprehend as we walk down the street. We live in an age now where the deepest scientific problems are buried away from our immediate perception. They concern the origin of the universe. They concern the relationships of subatomic particles. They concern the nature and structure of the human genome. Nobody can see these things without large bits of expensive equipment. But when I consider the problem of human variety I feel as Aristotle must have felt when he first walked down to the shore at Lesvos for the first time. The world is new again."

Secrets of the X chromosome, revealed!

Female X chromosome 'cracked' - "The discovery, by an international consortium of scientists, shows that females are far more variable than previously thought and, when it comes to genes, more complex than men." Nature reports two new studies; one on the complete sequencing of the X chromosome for humans, which sheds some light on how sex evolved and how women differ from men, and another on how women express many genes from X chromosomes previously thought dormant.

Transhumanism and effective use of the Web

More than Human - Ramez Naam's site promoting his new book (about emerging technologies for engineering human biology, more or less), has excerpts, a list of upcoming appearances, and even a full-fledged blog linking to articles and commentary that might be of interest to people curious about the book's transhumanist ideas. Now this is the way to do it.

At least the scientists can get along

Bridging the rift. A joint Israeli/Jordanian biological research centre straddling the border between the two nations is set to become operational in the near future. Scientists from Cornell and Stanford are involved as well. See what it'll look like (big PDF), and learn why studies of biosalinity and other forms of extreme biology are important.

Open Source Biology

BIOS-Biological Innovation for Open Society is an open source biotechnology initiative based in Australia. Along with its parent organization CAMBIA, it aims to foster a "protected commons" for scientific information and technology. Tools and techniques are shared, and can be improved and repackaged, just like in open source software.

Infrasound animals

"Infrasonic Symphony" Intrigued by reports of tsunami-avoidance behavior in Sri Lankan wildlife? Science News offers a timely antidote to simplistic mumbo-jumbo about the "mythical power" of animal earthquake detection with a detailed look at the latest research into low-frequency sound. The Elephant Listening Project is particularly interested in elephant rumblings that produce Rayleigh waves. "Mammals, birds, insects, and spiders can detect Rayleigh waves," notes The Explainer. "Most can feel the movement in their bodies, although some, like snakes and salamanders, put their ears to the ground in order to perceive it."

BioMotion Walker

The BioMotion Walker [flash] demonstrates that biologically and socially relevant information about a person is conveyed in biological motion patterns. It allows you to manipulate a number of parameters controlling the characteristics of human walking. You can interactively change biological properties, personality traits and emotional expression of a point-light walker. You can even help out their research here.

Got the right genes?

Predicting who'll benefit from anti-depressants From the study's abstract: "There are well-replicated, independent lines of evidence supporting a role for corticotropin-releasing hormone (CRH) in the pathophysiology of depression." The NY Times has a bit more readable explanation (reg-free link) of a recent investigation of into whether there is a genetic explanation for why some people get more from their drugs than others.

Microbes vs. Peak Oil

I want Life, F****r!

"We have [a substance] that extends the life of every species it's given to. We're 50 years ahead of where I thought we would be 10 years ago." While Harvard Medical School rules prevent David Sinclair from recommending product, "I know a number of scientists who think [it] is their best shot. Others satisfy themselves with a glass of red wine," which contains the compound. Too good to be true?

science

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.

it's all about the fish

The Starving Ocean : A large collection of articles by Debbie MacKenzie on the death of the ocean. The idea is that removing most of the fish from the sea might be sort of bad for the marine ecosystem as a whole. Her writing style is a bit kooky, but she has been right on some points (ie. the Grey Seal thing). Oh, and fishing is also responsible for the rise of atmospheric carbon dioxide.

The story of Ohh!

The story of Ohh! For men it is quick, easy and essential for reproduction. For women, it is slow, difficult and purely for pleasure. Yet despite such differences, it brings the sexes together and is the basis of the monogamy that distinguishes us from other animals.

The project was built with a grant from the National Science Foundation and has received an additional grant to expand the site to develop content for students and adults.

a penguin love story

Birds do it, bees do it... homosexual attachment and lovemaking are widespread in the animal kingdom, say biologists like Bruce Bagemihl, author of "Biological Exuberance." [For a longer, better-edited version of the same article, go here, but NYT reg. required.] Not everyone agrees, particularly those apt to quote the Bible to justify claims of a "natural revulsion to perverse sex."

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

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.
