Thoughts Can Fuel Some Deadly Brain Cancers

The simple act of thinking can accelerate the growth of many brain tumors.

That's the conclusion of a paper in Cell published Thursday that showed how activity in the cerebral cortex affected high-grade gliomas, which represent about 80 percent of all malignant brain tumors in people.

"This tumor is …

Transparent findings? 'Invisible' people less anxious, say scientists

The possibilities open to a person rendered invisible have been well explored in the worlds of science fiction and philosophy, not to mention the minds of adolescents.

Now neuroscientists in Sweden have simulated the effect using virtual reality and found, perhaps unsurprisingly, that the sensation …

40,000-year-old teeth suggest an ancient culture belonged to humans, not Neanderthals

Tens of thousands of years ago, the rise of humanity as we know it began. Modern humans spread from Africa to Europe and Asia, which were already populated by older Neanderthal cultures. The two groups interbred, adding some Neanderthal DNA to our present-day genes. The relatively sophisticated …
