Restoring seagrass beds: Is it for the birds?

...s a favored spot in the summer, with constant boat traffic in its shallow waters. Its underwater shoal grassbeds, however, have been much impacted by propeller damage; and much of the terrestrial vegetation on the island itself was destroyed by Hurricane Ivan in 2004. Drs. Heck and Dindo received a grant f...

A switch between life and death

...uced by the cell directly depends on the amount of traffic on the Hippo signaling pathway, and higher levels of bantam prompt more cell division. "Bantam is an unusual type of RNA molecule," Thompson says. "Normally, RNAs go on to make protein, but bantam is different. Its job is to regulate other RNAs by a...

Just like us, social stress prompts hamsters to overeat, gain weight

...erience in everyday life, such as getting stuck in traffic or trying to complete a major project at work. It is distinct from traumatic stress, such as suffering the death of a loved one. Traumatic stress typically dulls the human appetite, said Bartness, the study's senior researcher and an authority on obe...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

...allidum. Located deep in the brain, it's a kind of traffic center for signals from different areas of the brain that process tastes and pleasurable sensations. The researchers were able to track the activity of brain cells in that area while the rats received water, salt water and sugar water directly into...

Motor protein plays key role in connecting neurons

...t, a sort of two-way highway in the cell's highest traffic area, says Dr. Wen-Cheng Xiong, developmental neurobiologist at the Medical College of Georgia. Part of its cargo is DCC receptor which needs to move from the central nucleus where it's synthesized to the cell's periphery, Dr. Xiong and her collea...
