Potential Autoimmunity-inducing Cells Found In Healthy Adults
 It’s not just patients with autoimmune diseases like lupus and rheumatoid arthritis (RA) that have self-attacking immune cells—healthy people have them too, according to a new report. In healthy adults, however, these cells are maintained in an ‘off’ state.

How Certain Vegetables Combat Cancer
While it has been known for some time that eating cruciferous vegetables, such as broccoli, cauliflower, and cabbage, can help prevent breast cancer, the mechanism by which the active substances in these vegetables inhibit cell proliferation was unknown — until now. Scientists … have shown how the healing power of these vegetables works at the cellular level.

One World, Many Minds: Intelligence in the Animal Kingdom
The brains of other animals are not merely previous stages that led directly to human intelligence. Instead—as is the case with many traits—complex brains and sophisticated cognition have arisen multiple times in independent lineages of animals during the earth’s evolutionary history. With this new understanding comes a new appreciation for intelligence in its many forms. So-called lower animals, such as fish, reptiles and birds, display a startling array of cognitive capabilities. Goldfish, for instance, have shown they can negotiate watery mazes similar to the way rats do in intelligence tests in the lab.

What Can Swiss Cheese Teach Us About Dark Energy?
About 10 years ago, scientists reached the astonishing conclusion that our universe is accelerating apart at ever-increasing speeds, stretching space and time itself like melted cheese. The force that’s pushing the universe apart is still a mystery, which is precisely why it was dubbed “dark energy.” But is dark energy really real? Is our universe really accelerating? [Researchers] recently published a paper… looking at how giant holes in our “Swiss-cheese-like” universe might make space look as if it’s accelerating when it’s really not. They concluded these holes, or voids, are not sufficient to explain away dark energy; nevertheless, Vanderveld says it’s important to continue to question fundamental traits of the very space we live in.
