Science corner: ­Encouraging news on Ozone Layer

This September the United Nations released an encouraging update on the status of the ozone layer and the ozone hole over Antarctica. Evidence of progress in reversing ozone depletion offers good environmental news and some interesting parallels with climate change.

Big science questions remain

Science has advanced in leaps and bounds over the last several centuries. Our knowledge about the cosmos, our planet and life on Earth increases almost daily.

Winds of change in the tropical Pacific

Oregon on average offers a mild climate, but we have plenty of regional variation. Traveling from the coast to Eastern Oregon can present a range of temperatures and weather conditions that can be striking at certain times.

Science Corner: Genetics and DNA: An elegant way of communicating

One way of viewing modern biology is to make a list of unifying ideas that tie such a huge field of science together. The shortest list would consist of evolution alone, for as a biologist named Theodosius Dobzhansky once said, “Nothing in biology makes sense except in the light of evolution.”

Science Corner: Our rapidly aging earth

Science sometimes advances by giant leaps, but more often moves in small steps by gradually gathering new evidence. The calculated age of the Earth is a good example, having shifted from a few thousand to 4.5 billion years old over the last two centuries.

Science Corner: Climate change crosses disturbing threshold

It’s been nearly six months since my last rant about climate change, arguably one of the biggest science stories of our time. In early May we reached the milestone level of 400 parts per million carbon dioxide (CO2) in the atmosphere, a good excuse to revisit the latest signs of global warming.

We are all stardust

All life on Earth shares a common ancestor. You just have to trace the evolutionary tree over 3 billion years into the past to find it. And while family resemblances get harder to see the further back you go, modern science unmistakably ties us all together.
