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.

Pactamycin Analogs Offer New, Gentler Approach to Cancer Treatment
CORVALLIS, Ore. -- Researchers at Oregon State University are pursuing a new concept in treatment of epithelial cancer, especially head and neck cancer, by using two promising "analogs" of an old compound that was once studied as a potent anti-tumor agent, but long ago abandoned because it was too toxic. The analogs are more highly selective than the parent compound, pactamycin, which originally was found to kill all cells, from bacteria to mammals, by inhibiting their protein synthesis.

Hazing Remains a Concern in College Marching Bands, New Study Shows
CORVALLIS, Ore. -- Nearly a third of college marching band members surveyed in a national study observed hazing in their programs but few of the students reported the activities, often because of fears of retribution or loss of social standing, according to researchers.

New Method Developed to Assess Cancer Risk of Pollutants
CORVALLIS, Ore. - Scientists at Oregon State University have developed a faster, more accurate method to assess cancer risk from certain common environmental pollutants. Researchers found that they could analyze the immediate genetic responses of the skin cells of exposed mice and apply statistical approaches to determine whether or not those cells would eventually become cancerous.

Solomon Islands Dolphin Hunts Cast Spotlight on Small Cetacean Survival
NEWPORT, Ore. - A new study on the impact of 'drive-hunting' dolphins in the Solomon Islands is casting a spotlight on the increasing vulnerability of small cetaceans around the world. From 1976 to 2013, more than 15,000 dolphins were killed by villagers in Fanalei alone, where a single dolphin tooth can fetch the equivalent of 70 cents ($0.70 U.S.) - an increase in value of five times just in the last decade.

Global Decline of Large Herbivores May Lead to an 'Empty Landscape'
CORVALLIS, Ore. - The decline of the world's large herbivores, especially in Africa and parts of Asia, is raising the specter of an "empty landscape" in some of the most diverse ecosystems on the planet, according to a newly published study. Many populations of animals such as rhinoceroses, zebras, camels, elephants and tapirs are diminishing or threatened with extinction in grasslands, savannahs, deserts and forests, scientists say.

Researchers Find 200-year Lag Between Climate Events in Greenland, Antarctica
CORVALLIS, Ore. - A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture of the link between climate in the northern and southern hemispheres.
