Brain cancer self-organizes into streams, swirls, and spheres Brain cancer is not anarchy, say researchers but highly organized--self-organized. Researchers report that glioma cells build tumors by self-organizing into streams,10-20 cells wide, that obey a mathematically predicted pattern for autonomous agents flowing together. These streams drag along slower gliomas, may block entry of immune cells, and swirl around a central axis containing glioma stem cells that feed the tumor's growth.
How brain architecture leads to abstract thought Using 20 years of functional magnetic resonance imaging (fMRI) data from tens of thousands of brain imaging experiments, computational neuroscientists have created a geometry-based method for massive data analysis to reach a new understanding of how thought arises from brain structure.
Certain antidepressants linked to heightened risk of mania and bipolar disorder Taking certain antidepressants for depression is linked to a heightened risk of subsequent mania and bipolar disorder, new research reveals. The strongest association seemed to be for serotonin reuptake inhibitors, or SSRIs for short, and the dual action antidepressant venlafaxine, the analysis indicated.
Big Beef keeps getting bigger, thanks to growth drugs with unclear safety records When it comes to cattle, size certainly does matter. But how big is too big? And at what cost? The beef industry has come to rely on growth-inducing drugs to bulk up cattle before slaughter. But the consequences of using such drugs are a concerning unknown Continue Reading
Many US wells tainted with arsenic Arsenic is the biggest public-health problem for water in the United States -- yet we pay far less attention to it than we do to lesser problems. Private wells present continuing risks. Even low doses of arsenic may Continue Reading

Largest ever genome-wide study strengthens genetic link to obesity While diet and exercise are important, new findings sharpen the role genetics play in people’s tendency to gain weight and where the fat is stored. This work is the first step toward finding individual genes that play key roles in body shape and size. Continue Reading
