Professor Steven Chu, who was appointed Energy Secretary under as much optimism as can be imagined in late 2008, has officially resigned, a move everyone knew was coming.

Except for his irrational CO2 fanaticism - an energy Nobel laureate who takes a job in the cabinet has to know we can't just cut off CO2, the way an academic working at a national lab can talk about it - Chu was a much safer choice than the UFO believers and Doomsday prophets the Obama administration was determined to hire after his victory in November of that year.

Sociologists have settled an important debate - namely, do women really want a man that does housework. The answer is 'no', according to an important new paper which found that married men and women who divide household chores in traditional ways report having more sex than couples who share the women's work.  

It's no shock to know there is no anthropology without beer. No history either. Really, it took alcohol to get someone to write down mundane events in longhand.  And beer-making equipment was prized above all else, that is why many of our earliest finds from ancient civilizations have been related to it.

figshare, a Digital Science portfolio company, has announced a new partnership with open access publisher Public Library of Science (PLoS) to host the supplemental data for all seven PLoS journals, as well as provide a widget that will enable PLoS users to view data in the articles in the browser alongside the content. 

 figshare provides a free way for researchers to publish, share and get credit for their research data, hosting videos, datasets, graphs, figures and images. By partnering with figshare, PLoS can host data accompanying their publications, making the data easier to access for future use. Through figshare's new widgets, users will also be able to visualize the research objects within the browser. 

A new paper outlines the many pitfalls associated with simulation methods such as Monte Carlo algorithms and other commonly used molecular dynamics approaches.

If a numerical model simulating 25,000 generations of evolution within computers is to be believed, Cornell University engineering and robotics researchers may have discovered why biological networks tend to be organized as modules – a finding that will lead to a deeper understanding of the evolution of complexity.

And they say it will help evolve artificial intelligence. Robot brains with the grace and cunning of animals? What could go wrong?

There is a reason for the disparity between charitable giving among people who advocate smaller government and larger government; people who advocate larger government already feel like they are doing their part by paying more in taxes, so they give less to charity.

Two new research papers signal how the next class of powerful medications may currently reside at the bottom of the ocean. 

Sea life studies could aid researchers in several ways, including the development of new medications and perhaps biofuels. Because many of these ocean animal species have existed in harmony with their bacteria for millions of years, these benign bacteria have devised molecules that can affect body function without side effects - and therefore better fight disease.

A new estimate is that each intravenous drug user contracting Hepatitis C could infect around 20 other people with the virus, half of these transmissions occurring in the first two years after the user is first infected.

During the short time that Roy Thomas took over as writer of the Fantastic Four from Stan Lee, the original writer, it got a lot better.  I know, I know, that is blasphemy.(1) There is a reason Stan Lee gets a cameo in every movie about every Marvel superhero - he co-created them all, he made them all famous. He is a bigger legend than the guys behind Batman or Superman, his economic impact rivals the GDP of many small nations.

Still, when is the last time you read a good Stan Lee comic? Eventually, people are just phoning it in. And that had happened on the Fantastic Four by 1972.
