McGill University scientists say they've discovered a small molecule in coral that can be used to block the replication of certain viruses.
The Canadian research shows the naturally occurring product, hippuristanol, specifically impairs the machinery used to make proteins.
Lead author of the study, Jerry Pelletier, and colleagues isolated hippuristanol from the coral Isis hippuris. The researchers found that molecule prevents a protein, eIF4A, from binding to mRNA, which carries the code to make proteins from DNA to specific sites of protein synthesis in the cell.
By binding to the mRNA, eIF4A initiates the translation of the protein code and Hippuristanol prevents replication by inhibiting that process.
The research appears in the April issue of the journal Nature Chemical Biology

Diversity of plant-eating fishes may be key to recovery of coral reefs
For endangered coral reefs, not all plant-eating fish are created equal. A report scheduled to be published this week in the early edition of the journal
Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring coral reefs, which are declining dramatically worldwide. The conclusion results from a long-term study that found significant recovery in sections of coral reefs on which fish of two complementary species were caged.
Paradigm shift: Switch for programmed cell death promotes spread of glioblastoma
Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis. Therefore, tumors are often resistant to chemotherapy or radiation therapy, whose effect is based on forcing tumor cells to commit suicide.

Immediate action needed to save corals from climate change
The journal
Science has published a paper today that is the most comprehensive review to date of the effects rising ocean temperatures are having on the world’s coral reefs. The Carbon Crisis: Coral Reefs under Rapid Climate Change and Ocean Acidification, co-authored by seventeen marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.

Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.

A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. This fluorescent marker protein may shed light on brain cell defects believed to play a role in various neurological diseases. The researchers describe how this marker works in mice in the December 20, 2006, issue of

Sea coral hope for fighting gastroenteritis
A molecule found in coral is effective in fighting the type of virus that causes gastroenteritis, giving hope for the development of better treatments for the illness, according to new research. At present, treatments do not fight the virus itself but instead address its symptoms, such as dehydration and diarrhoea.
