A new optical device at Sandia National Laboratories that helps researchers image pollutants in combusting fuel sprays might lead to clearer skies in the future.

Researchers have shown free radical concentrations in lichens to be directly related to air pollution.

NASA’s Aqua satellite and the NASA-NOAA Suomi NPP satellite provided imagery of Damrey as it strengthened into a typhoon in the South China Sea.

On July 22, 1847, a scouting party from The Church of Jesus Christ of Latter-day Saints stood above the Great Salt Lake Valley in modern-day Utah; by 1870, more than 18,000 followers had colonized the valley and surrounding region, displacing Native American populations to establish dispersed farming communities. While historians continue to debate the drivers of this colonization event, a new study from the University of Utah proposes that agricultural productivity drove dispersal patterns in a process that led the current distribution of Utah populations today.

Flu shot season is here. But as you head to the doctor’s office or pharmacy to get vaccinated, scientists are working to make this yearly ritual a thing of the past. Researchers around the world, including at the University of Rochester Medical Center (URMC), are pursuing a “universal” flu vaccine, one that would protect against most or all seasonal and pandemic strains of the flu virus.

The ESA (European Space Agency) and NASA mission SOHO — short for Solar and Heliospheric Observatory — got a visit from an old friend this week when comet 96P entered its field of view on Oct. 25, 2017. The comet entered the lower right corner of SOHO’s view, and skirted up and around the right edge before leaving on Oct. 30. SOHO also spotted comet 96P in 1996, 2002, 2007 and 2012, making it the spacecraft’s most frequent cometary visitor.

Is it any wonder that most happiness idioms are associated with nature? Happy as a pig in muck, happy as a clam, happy camper.

Proxima Centauri is the closest star to the Sun. It is a faint red dwarf lying just four light-years away in the southern constellation of Centaurus (The Centaur). It is orbited by the Earth-sized temperate world Proxima b, discovered in 2016 and the closest planet to the Solar System. But there is more to this system than just a single planet. The new ALMA observations reveal emission from clouds of cold cosmic dust surrounding the star.

Many climate-related studies, such as detection and attribution of historical climate change, projections of future climate and environments, and adaptation to future climate change, heavily rely on the performance of climate models. Concisely summarizing and evaluating model performance becomes increasingly important for climate model intercomparison and application, especially when more and more climate models participate in international model intercomparison projects. 

Young hockey players who have suffered concussions may still show changes in the white matter of the brain months after being cleared to return to play, researchers at Western University have found through sophisticated Magnetic Resonance Imaging (MRI) techniques.
