The anti-inflammatory drug hydroxychloroquine does not significantly reduce admission to intensive care or death in patients hospitalized with pneumonia due to COVID-19, finds a study from France. And a randomized clinical trial from China shows that hospitalized patients with mild to moderate persistent covid-19 who received hydroxychloroquine did not clear the virus more quickly than those...

Persistent inequitable exposure to air pollution in Salt Lake County schools
Salt Lake County, Utah's air pollution varies over the year, and at times it is the worst in the United States. The geography traps winter inversions and summertime smog throughout the Salt Lake Valley, but underserved neighborhoods—and their schools—experience the highest concentrations. Previous research has shown pollution disparities using annual averages of PM 2.5 levels, the tiny...
Online romance scams: A modern form of fraud
Over the last 20 years, the rapid development of digital communication technology has given rise to new forms of social interaction on social media. Digital communication technologies can overcome physical, social and psychological barriers in building romantic relationships.

Persistent pollutants and the unintended side effects of the Montreal Protocol
Bob McDonald's blog: The Montreal Protocol banned chemicals to protect the Earth's ozone. Now, the alternatives to those chemicals are showing up in Arctic ice and we don't know if they pose a threat to human...
Big data and synthetic chemistry could fight climate change and pollution
Scientists at the University of South Carolina and Columbia University have developed a faster way to design and make gas-filtering membranes that could cut greenhouse gas emissions and reduce pollution.
Modern sea-level rise linked to human activities, Rutgers research reaffirms
New research by Rutgers scientists reaffirms that modern sea-level rise is linked to human activities and not to changes in Earth's orbit.
Ocean 'breathability' key to past, future habitat of West Coast marine species

Ocean breathability, which combines the oxygen levels, a species' oxygen needs and the water temperature, matches the shifts in northern anchovy populations from the 1950s to today. Under climate change, this key forage fish may no longer be able to survive in the southern part of its range, off Mexico and southern California.
Food webs determine the fate of mercury pollution in the Colorado River, Grand Canyon

In the Grand Canyon reach of the Colorado River, two species play an outsized role in the fate of mercury in the aquatic ecosystem, and their numbers are altered by flood events.
Modern sea-level rise linked to human activities

- 20/5/15 20:46
New research reaffirms that modern sea-level rise is linked to human activities and not to changes in Earth's orbit. Surprisingly, the Earth had nearly ice-free conditions with carbon dioxide levels not much higher than today and had glacial periods in times previously believed to be ice-free over the last 66 million years, according to a new article.
Key to preserving The Scream

- 20/5/15 20:46
Moisture is the main environmental factor that triggers the degradation of the masterpiece The Scream (1910) by Edvard Munch, according to new findings using a combination of in situ non-invasive spectroscopic methods and synchrotron X-ray techniques.
USGS reports magnitude-6.5 earthquake in western Nevada
Authorities in western Nevada checked for possible highway damage following a magnitude 6.5 earthquake in a remote area early Friday.
Typhoon leaves 1 dead, extensive damage in Philippine towns
Strong winds and rain from Typhoon Vongfong left at least one person dead and damaged hundreds of homes and coronavirus isolation facilities along with rice and corn fields in five hard-hit eastern towns, a governor said Friday.
Scientists break the link between a quantum material's spin and orbital states
In designing electronic devices, scientists look for ways to manipulate and control three basic properties of electrons: their charge; their spin states, which give rise to magnetism; and the shapes of the fuzzy clouds they form around the nuclei of atoms, which are known as orbitals.
Ocean 'breathability' key to past, future habitat of West Coast marine species
Marine life off the West Coast, from Mexico up through Canada, inhabit the California Current. The cool, nutrient-rich water supports life from invisible phytoplankton to the economically important salmon, rockfish and Dungeness crab to the majestic orcas.
