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.

Some time this month, in Poker Flat, Alaska, a team of scientists from  The Aerospace Corporation of El Segundo, Calif.and NASA's Goddard Space Flight Center of Greenbelt, Md., will launch a sounding rocket up through the Northern Lights. 

Biologists have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes. 

Bioelectric signals underlie an important set of control mechanisms that regulate how cells grow and multiply. The study investigated the bioelectric properties of cells that develop into tumors in Xenopus laevis frog embryos.
