Research reveals air pollution can alter the effectiveness of antibiotics and increases the potential of disease

Leicester research reveals the impact of black carbon on bacteria in the respiratory tract

Cigarette smoke curbs lung's self-healing

Smoke from cigarettes blocks self-healing processes in the lungs and consequently can lead to chronic obstructive pulmonary disease (COPD). Researchers at the Helmholtz Zentrum München, partner in the German Center for Lung Research (DZL), and their international colleagues have reported this in the American Journal of Respiratory and Critical Care Medicine.

Aging faces could increase security risks

Images of our faces exist in numerous important databases – driver’s license, passport, law enforcement, employment – all to accurately identify us. But can these images continue to identify us as we age?

UBC team develops mobile sensors to monitor urban greenhouse gas emissions

Cities play a key role in reducing greenhouse gas emissions to combat climate change, but directly measuring emissions remains a challenge.

New USGS Streamgages Provide Flood Monitoring for Additional Philadelphia Neighborhoods

Philadelphia communities along the Schuylkill River and Darby Creek now have new tools to help inform residents of impending flooding. The U.S. Geological Survey recently installed three new streamgages in Manayunk, Eastwick, and downtown near 30th St., which will monitor water levels, and provide vital data used by emergency managers and flood forecasters to help protect lives and property.

Concurrent heat waves, air pollution exacerbate negative health effects of each

The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of California, Irvine.

“The weather factors that drive heat waves also contribute to intensified surface ozone and air pollution episodes,” said UCI professor of Earth system science Michael J. Prather, co-author of the study, published this week in Proceedings of the National Academy of Sciences. “These extreme, multiday events tend to cluster and overlap, worsening the health impacts beyond the sum of their individual effects.”

Mollusk graveyards are time machines to oceans' pristine past

A University of Florida study shows that mollusk fossils provide a reliable measure of human-driven changes in marine ecosystems and shifts in ocean biodiversity across time and space.

Collecting data from the shells of dead mollusks is a low-cost, low-impact way of glimpsing how oceans looked before pollution, habitat loss, acidification and explosive algae growth threatened marine life worldwide. Mollusk fossils can inform current and future conservation and restoration efforts, said Michal Kowalewski, the Jon L. and Beverly A. Thompson Chair of Invertebrate Paleontology at the Florida Museum of Natural History on the UF campus and the study’s principal investigator.

Using Google to map our ecosystem

Researchers in the Singapore-ETH Centre’s Future Cities Laboratory developed a method to quantify ecosystem services of street trees. Using nearly 100,000 images from Google Street View, the study helps further understanding on how green spaces contribute to urban sustainability.

Do you remember the last time you escaped the hot summer sun to enjoy a cool reprieve in the shade beneath a broad-leafed tree? While sizzling summer days may seem far away right now in the northern hemisphere, tropical cities like Singapore deal with solar radiation on a daily basis.

First Solar Images from NOAA's GOES-16 Satellite

The first images from the Solar Ultraviolet Imager or SUVI instrument aboard NOAA’s GOES-16 satellite have been successful, capturing a large coronal hole on Jan. 29, 2017.

The sun’s 11-year activity cycle is currently approaching solar minimum, and during this time powerful solar flares become scarce and coronal holes become the primary space weather phenomena – this one in particular initiated aurora throughout the polar regions. Coronal holes are areas where the sun's corona appears darker because the plasma has high-speed streams open to interplanetary space, resulting in a cooler and lower-density area as compared to its surroundings.

Bhutan's stumbling block to becoming the greenest nation on the planet

Bhutan is well on its way to becoming the greenest nation on the planet. In his Special Report for the Ecologist, Photojournalist MICHAEL BUCKLEY explores the reasons why the country's ecosystems and dazzling biodiversity remain intact - and highlights the one thing that threatens this admirable integrity...
