Jurassic Pain: Giant 'Flea-like' Insects Plagued Dinosaurs 165 Million Years Ago

Published: May 1, 2012.
Released by Oregon State University  

CORVALLIS, Ore. – It takes a gutsy insect to sneak up on a huge dinosaur while it sleeps, crawl onto its soft underbelly and give it a bite that might have felt like a needle going in – but giant "flea-like" animals, possibly the oldest of their type ever discovered, probably did just that.

Beyond Prevention: Sulforaphane May Find Possible Use for Cancer Therapy
CORVALLIS, Ore. - New research has identified one of the key cancer-fighting mechanisms for sulforaphane, and suggests that this much-studied phytochemical may be able to move beyond cancer prevention and toward therapeutic use for advanced prostate cancer.

Deworming Programs in Animal, Human Populations May Have Unwanted Impacts
CORVALLIS, Ore. - A study of the effects of worming medications on infectious disease in wildlife herds showed an unexpected and alarming result - it helped reduce individual deaths from a bovine tuberculosis infection, but hugely increased the potential for spread of the disease to other animals. The findings, from one of the first field studies ever done on this issue, will be published Friday in the journal Science.

Wave Energy Integration Costs Should Compare Favorably to Other Energy Sources
CORVALLIS, Ore. - A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.

'Glowing' New Nanotechnology Guides Cancer Surgery, Also Kills Remaining Malignant Cells
CORVALLIS, Ore. - Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells - a system that will help surgeons identify malignant tissues and then, in combination with phototherapy, kill any remaining cancer cells after a tumor is removed. It's about as simple as, "If it glows, cut it out." And if a few malignant cells remain, they'll soon die.

Introverts Could Shape Extroverted Co-workers' Career Success, OSU Study Shows

CORVALLIS, Ore. - Researchers for the first time have developed a method to track through the human body the movement of polycyclic aromatic hydrocarbons, or PAHs, as extraordinarily tiny amounts of these potential carcinogens are biologically processed and eliminated.

No Laughing Matter: Nitrous Oxide Rose at End of Last Ice Age
CORVALLIS, Ore. - Nitrous oxide (N2O) is an important greenhouse gas that doesn't receive as much notoriety as carbon dioxide or methane, but a new study confirms that atmospheric levels of N2O rose significantly as the Earth came out of the last ice age and addresses the cause.
