The circadian clock coordinates physiological and behavioral processes on a 24-hour rhythm, allowing animals to anticipate changes in their environment and prepare accordingly.

Scientists already know that some genes are controlled by the clock and are turned on only one time during each 24-hour cycle but now researchers at the University of Pennsylvania School of Medicine and the Salk Institute for Biological Studies have found that some genes are switched on once every 12 or 8 hours.

Genome sequencing is getting better and faster.  Two months ago we had the first draft of the neanderthal genome and now scientists from the University of Maryland have published their assembly of the Bos taurus - the domestic cow.  Sure that's not as exciting to the wider population but it's important to the genetics community.

When I was a kid, 'toxic' assets were not assets at all; they were called 'liabilities.'    That's why asset and liability columns exist on these things called 'spreadsheets.'   But I am neither a politician nor a banker so I have poor grasp of things I know nothing about.  Much like this Timothy Geithner guy.

But apparently toxic assets do exist because banks around the world are being dragged down by them.   Who would have thought that mortgage-backed securities based on a housing bubble fueled by people who couldn't afford their homes would ever be a problem?   Well, me, but I was told I hated poor people and minorities for daring to ask.

A process called ‘dark gulping’ may solve the mystery of the how supermassive black holes were able to form when the Universe was less than a billion years old.

Dr Curtis Saxton will be presenting the study at the European Week of Astronomy and Space Science at the University of Hertfordshire in Hatfield.

This is part 1 of 6 in a brief series describing the history of English and its grammar.

What is Grammar?

A grammar is a set of rules for the communal use of a language. A language can never become a truly national language unless all users of that language share common rules for how words are invented, used and strung together in sentences.  When by some means the users of a language no longer share these rules, the language fragments into dialects and eventually, new languages.  It is useful to think of dialects as not being quite so large an obstacle as different languages are to trade, commerce and exchange of ideas between regions.

I recently came across a radio lecture given by Dr Lee Alan Dugatkin on 7.6.2007, titled "Is Goodness Natural?" It deserves comment. (An article on the same subject but with some differences in text was published at Huffington Post.)

The talk began well with some historical background describing the attempts by Charles Darwin, Thomas Huxley, Peter Kropotkin and W. D. Hamilton to explain the origin of goodness, (in the sense of being nice to one another,) in light of evolutionary theory. He concluded that the first three had failed to adequately explain goodness, (Kropotkin’s great work “Ethics” was obviously overlooked) but that Hamilton had solved the dilemma with a “simple but elegant mathematical equation.”

This week, researchers and scientists at UCLA are doing something unusual: They are organizing a demonstration against the violent tactics of certain animal rights groups.

This week, people in labs across the country are saying: It's about time.

-- It's about time that people came out of their labs and off the bench and took a public stand, rather than relying upon trade groups and animal providers to make the case for them

-- It's about time that science generated its own leaders to pro-actively make the case for animal testing, rather than rely on the usual ( and rather suspect) cast of pharmaceutical companies and toxicology labs

It's Earth Day, in case you can't tell by our swanky green Earth logo in the header, and that means people will be thinking about Nature (the bitch, not the magazine) and our impact on her.   I didn't say people would be thinking clearly, but they will be thinking.

So instead of shocking and awing you with my dark humor and divine genius, I will instead ask a question; what kind of science could you do if you got sent back to 10,000 BC?

Researchers writing in Nature magazine say the fossil skeleton of a newly discovered carnivorous animal, Puijila darwini, is a "missing link" in the evolution of the group that today includes seals, sea lions, and the walrus. 

Modern seals, sea lions, and walruses all have flippers—limb adaptations for swimming in water. These adaptations evolved over time, as some terrestrial animals moved to a semi-aquatic lifestyle. Until now, the morphological evidence for this transition from land to water was weak.

Using information from a suite of telescopes, astronomers have discovered a mysterious, giant object that existed at a time when the universe was only about 800 million years old. Objects such as this one are dubbed extended Lyman-Alpha blobs; they are huge bodies of gas that may be precursors to galaxies. This blob was named Himiko for a legendary, mysterious Japanese queen. It stretches for 55 thousand light years, a record for that early point in time. That length is comparable to the radius of the Milky Way's disk.
