Humans may be adding large amounts of carbon dioxide to the atmosphere by using groundwater faster than it is replenished, according to new research. This process, known as groundwater depletion, releases a significant amount of carbon dioxide into the atmosphere that has until now been overlooked by scientists in calculating carbon sources, according to the new study.

A genomic study of Puerto Rico's Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees' rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.

In 2016, news about the Zika virus in Brazil made the headlines in Europe for the first time. With approximately 65 million people affected, it is one of the largest epidemics in the last few years. The Olympics additionally fuelled fears that the virus could spread globally. When the first cases of newborns with microcephaly, i.e. malformations of the brain, were observed in connection to Zika, it became apparent that further research was called for. The DZIF responded to this global challenge and, under the leadership of Jan Felix Drexler, Charité – Universitätsklinikum Berlin, initiated a German alliance project with Brazilian scientists, which investigates the pathogenesis and epidemiology of Zika.

Some impacts of global warming – such as sea level rise and coastal flooding – are already locked in and unavoidable, according to a major research project. 

Two new studies from The University of Texas at Austin have significantly improved scientists’ ability to predict the strength and duration of droughts caused by La Niña – a recurrent cooling pattern in the tropical Pacific Ocean. Their findings, which predict that the current La Niña is likely to stretch into a second year, could help scientists know years in advance how a particular La Niña event is expected to evolve.

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.

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.

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.

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.

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