University of Oregon research maps major shifts in Colorado River history
November 16, 2017 08:28 AM - University of Oregon

Geologists have long debated how and when the Colorado River made its first connection to the ocean. In a new study, a team led by the UO’s Becky Dorsey has helped pull the river’s story together.

The river did not, as many thought, simply roar down out of the Colorado Plateau and pour into the Gulf of California.

Is that burger bad for your knees?

One could say that biomedical engineering grad Kelsey Collins is walking in the footsteps of giants.

When Collins started out as a grad student at the University of Calgary’s Human Performance Laboratory, she didn’t know that her path would lead her to a postdoctoral appointment at Washington University in St. Louis — home to no fewer than 17 Nobel laureates in medicine and physiology, and a world-renowned institute for orthopaedic research.

Study Reveals Structure and Origins of Glacial Polish on Yosemite's Rocks
November 15, 2017 03:16 PM - University of California - Santa Cruz

The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial polish, are common in the Sierra Nevada and other glaciated landscapes.

Pacific Island Countries Could Lose 50-80% of Fish in Local Waters Under Climate Change
November 15, 2017 01:27 PM - Nippon Foundation-Nereus Program

Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new Nippon Foundation-Nereus Program study published in Marine Policy. This area of the ocean is projected to be the most severely impacted by aspects of climate change.

Study Finds People with Certain Blood Types Have Increased Risks of Heart Attack During Periods of High Air Pollution
November 15, 2017 01:13 PM - Jess Gomez

Individuals who have A, B, or AB blood types have an elevated risk of having a heart attack during periods of significant air pollution, compared to those with the O blood type, according to new research from the Intermountain Medical Center Heart Institute and Brigham Young University.

The new study is unique in that it links increased risk of heart attack associated with small particulate pollution to increased risk of heart attack for people with certain blood types who have coronary artery disease.

The Global Precipitation Measurement mission or GPM core satellite provided data on rainfall over Vietnam from the remnants of former Tropical Storm Haikui.

Amazon's Recovery Limited by Climate Change
November 15, 2017 12:20 PM - University of Edinburgh

Deforested areas of the Amazon Basin have a limited ability to recover because of recent changes in climate, a study shows.

Scripps Scientists Use Photomosaic Technology to Find Order in the Chaos of Coral Reefs
November 15, 2017 11:47 AM - University of California - San Diego

In a study published recently in Coral Reefs, scientists from Scripps Institution of Oceanography at UC San Diego created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll, and made surprising discoveries around coral spatial ecology. The scientists, led by graduate student Clinton Edwards, canvassed more than 17,000 square feet of reef, and 44,008 coral colonies, taking more than 39,000 images that were then stitched together to create 3D photomosaics that encompassed the reef. 

Low dose, constant drip: Pharmaceuticals & personal care products impact aquatic life
November 15, 2017 11:41 AM - Cary Institute of Ecosystem Studies

Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption – not just organism death – are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. So reports a new study published this week in Elementa.

FIREBIRD II and NASA Mission Locate Whistling Space Electrons' Origins
November 15, 2017 11:36 AM - NASA / Goddard Space Flight Center

Scientists have long known that solar-energized particles trapped around the planet are sometimes scattered into Earth’s upper atmosphere where they can contribute to beautiful auroral displays. Yet for decades, no one has known exactly what is responsible for hurling these energetic electrons on their way. Recently, two spacecraft found themselves at just the right places at the right time to witness first hand both the impulsive electron loss and its cause.
