Whether you're a professional, a student, an amateur, an enthusiast, whatever! Lots of atheists love science. Might as well have a group for it!

Feel free to nerd out, link articles, talk about your favorite field of research, whatever!

I've been super busy with school this semester -- no time for Atheist Nexus, sadly!!
If anyone who's around here a lot wants me to toss them moderation privileges to run this group or anything, just send me (Sara) a message! Thanks!

Removed ability to send mass messages to everyone in the group. At 1000+ members, that seems like asking for spam.

Offer still open if anyone active in the group wants moderation privileges, but it appears everything has been going smoothly with all kinds of great discussions without moderation. Fantastic! :)

Humans' Big Brains Tied To Chimps' Immunity?


It's a provocative — even astonishing — hypothesis: Could the same set of genes that explains why chimpanzees are protected from some diseases also explain why humans have big brains?


That's what researchers at Stanford University are suggesting.


The genes in question control a type of white blood cell known as natural killer cells, or NK cells.


"They can make a big difference as to whether you get sick, or you don't get sick," says Peter Parham, a professor of cell biology at Stanford. Parham has been studying the genes that control NK cells. And it's not a simple picture — there are a lot of genes involved.

though they are all being read.

Maybe that's a good indication that it is a worthwhile book. : )

Thanks DG, it looks super fun :D My local library even has copies of it, though they are all being read.

The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements

Science magazine reporter Kean views the periodic table as one of the great achievements of humankind, "an anthropological marvel," full of stories about our connection with the physical world. Funny, even chilling tales are associated with each element, and Kean relates many. The title refers to gallium (Ga, 31), which melts at 84ËšF, prompting a practical joke among "chemical cognoscenti": shape gallium into spoons, "serve them with tea, and watch as your guests recoil when their Earl Grey ˜eats™ their utensils." Along with Dmitri Mendeleyev, the father of the periodic table, Kean is in his element as he presents a parade of entertaining anecdotes about scientists (mad and otherwise) while covering such topics as thallium (Tl, 81) poisoning, the invention of the silicon (Si, 14) transistor, and how the ruthenium (Ru, 44) fountain pen point made million for the Parker company. With a constant flow of fun facts bubbling to the surface, Kean writes with wit, flair, and authority in a debut that will delight even general readers.

I've just writeen this: http://imaginaryfriendsshow.com/?p=144 "Science Verifies Ancient Religious Claim!" about the new studies on the 'biblical exodus'.

Science, comedy... got to loves its!

This was posted on another site, so I'm crossposting here.

These chickens are male on one side of their bodies, and female on the other. They're called gynandromporphs.


Here is one science blog explaining the phenomenon, and here is a follow up post. Below is a short video.

Here is an excerpt from the articles (discussing the bird pictured above):

The animal on the right is no ordinary chicken. Its right half looks like a hen but its left half (with a larger wattle, bigger breast, whiter colour and leg spur) is that of a cockerel. The bird is a ‘gynandromorph‘, a rare sexual chimera. Thanks to three of these oddities, Debiao Zhao and Derek McBride from the University of Edinburgh have discovered a truly amazing secret about these most familiar of birds – every single cell in a chicken’s body is either male or female. Each one has its own sexual identity. It seems that becoming male or female is a very different process for birds than it is for mammals.


Here is another photo I found:



And somewhat related, here is an entry on Parthenogenesis, a form of asexual reproduction in which female insects and animals reproduce without male fertilization, producing another female offspring.

Interesting stuff.

Thanks Mrina. I've passed that along.

We are going backwards in America and it is painful to see. Soon it'll be like the Dark Ages...

Video: 30 Years of Asteroid Discoveries



This animation using data from observatories and amateurs around the world plots the positions of all the known asteroids in the solar system in 1980, and adds new ones as they are discovered. The pace and patterns of asteroid discovery give a neat visual illustration of the history of solar system exploration.

New asteroids appear in flashes of white, to make them easy to pick out. The final color codes for how close the object comes to Earth: Asteroids that cross Earth’s orbit are shown in red, “Earth approachers” that come to 1.3 times the Earth-sun distance are yellow, and all others are green. The bunches of new asteroids follow Earth in its orbit, usually in the region directly opposite the sun (that is, in the Earth’s night sky). Some clusters appear on the line between Earth and Jupiter, the side effects of surveys looking for Jovian moons.

In the mid-1990s, the pace of discovery picks up, showing the results of automated sky surveys. By 2001, the area just outside the orbit of Mars is filled in by a bright green ring of asteroids, and it keeps getting denser.

The beginning of 2010 brings a new pattern of discovery, with new asteroids fanning out on either side of the Earth. This new pattern is thanks to the Widefield Infrared Survey Explorer, an infrared space telescope that is expected to find hundreds of new asteroids by seeking their heat rather than their light.

According to the YouTube notes, “Currently we have observed over half a million minor planets, and the discovery rates snow no sign that we’re running out of undiscovered objects.”

The video was created using the ‘astorb.dat‘ data created by astronomer Ted Bowell of the Lowell Observatory and colleagues.

CORRECTION: The original version of this article attributed the data to the Arecibo Observatory in Puerto Rico. It actually came from observatories all over the world, and was compiled by the Minor Planet Center and the Lowell Observatory.

Someone else posted it on another site. It is a well done video.
