Erratic Black Hole Regulates Itself

New results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce.  These results suggest that these black holes have a mechanism for regulating the rate at which they grow.

Cracking the Crusts of Neutron Stars

Research by Michigan State University scientists is helping shed light on neutron stars, city-sized globs of ultra-dense matter that occasionally collapse into black holes. A team led by Betty Tsang, a professor at MSU's National Superconducting Cyclotron Laboratory, has had some success in measuring a key nuclear quality that may make it easier to describe the outer crusts of such stars.

Mutated Gene in Zebrafish Sheds Light on Blindness in Humans

Among zebrafish, the eyes have it. Inside them is a mosaic of light-sensitive cells whose structure and functions are nearly identical to those of humans. There, biologists at The Florida State University discovered a gene mutation that determines if the cells develop as rods (the photoreceptors responsible for dim-light vision) or as cones (the photoreceptors needed for color vision).

Researchers Develop Flow Sensors That Mimic Blind Fish

The fish species Astyanax fasciatus cannot see, but their unique technique for sensing their environment and the movement of water around them with gel-covered hairs that extend from their bodies may inspire a new generation of sensors that perform better than current active sonar.

Insurance Coverage No Peace of Mind for Parents

Trouble paying health plan premiums and difficulty affording out-of-pocket expenses for medications aren't just problems of the uninsured anymore. They're also concerns for families with private insurance, according to the C.S. Mott Children's Hospital National Poll on Children's Health.

Inhaling a Heart Attack: How Air Pollution Can Cause Heart Disease

Accumulating evidence indicates that an increase in particulate air pollution is associated with an increase in heart attacks and deaths. The relatively new field of environmental cardiology examines the relationship between air pollution and heart disease. A symposium in the Environmental Factors in Heart Disease will take place April 21 at the Experimental Biology conference in New Orleans.

Symposium to Look at Genetic Basis of Exercise

How many genes play a role in the body's ability to adapt to exercise? Mark Olfert of the University of California and Claude Bouchard of the Pennington Biomedical Research Center will answer that question and provide insight into why some people adapt to exercise more easily than others at a symposium at the Experimental Biology Conference in New Orleans on April 20.
