Portland State virus study receives major NASA grant

Portland State biologist Ken Stedman has received a $540,000 grant from NASA to study the evolution of viruses, which may shed light on how viruses form, adapt and infect hosts.

The study stems from a bizarre virus Stedman discovered in a hot spring at Lassen Volcanic National Park five years ago. The virus’s genetic code is derived from both DNA and its evolutionary predecessor, RNA. The vast majority of life on Earth switched its genetic code from RNA to DNA about four billion years ago, so the fact that this virus has both is highly unusual, according to Stedman.

Portland State researcher discovers new species of South American rabbit

A Portland State University researcher discovered that a rabbit known for centuries to exist in South America is different enough from its cousins to be its own unique species.

“At a time when species are going extinct every day, it’s encouraging to know we can add one back on the list of survivors,” said PSU biology professor Luis Ruedas. 

His findings will be published May 17 in the Journal of Mammalogy.

OPB: Thousands Hit The Streets For Portland's March For Science

Read the story on OPB.

Scientists, students, and families carried signs and chanted “Earth Day is every day.” Some, like Barbara Martin, even dressed for the occasion.

“I’ve got on my lab coat with my stethoscope and my sign says ‘Got Polio? Me neither. Thanks, science,’” said Martin, who was also sporting a green knit hat with an ohm symbol in the middle, the electrical sign for resistance.
