A class of materials that once looked as if it might revolutionize everything from solar cells to frying pans -- but fell out of favor in the early 2000s -- could be poised for commercial resurrection, new findings suggest.

A new automated numerical scheme is proposed for upper tropospheric cyclones (cutoff lows) and their earlier development stage as troughs (preexisting troughs). The proposed scheme has the capacity of early stage detection and can extract locations with transitions that are as smooth as possible and estimate their intensities, sizes, and...

Fraudulent practices in food production, especially false claims of geographical origin, cause billions of dollars in economic damage every year. Botanists have now developed a model that can be used to determine the origin of food in an efficient and low-cost manner.

A new study speaks to the importance of public awareness programs in keeping residents -- and emergency management offices -- informed about rare but potentially lethal natural events in their area.

The full magnitude of the impact of smoke from seasonal fires in Central Africa - and in particular, the potential climate warming from the absorption by the black carbon component of the aerosol - is underestimated by some climate models over the South-East Atlantic, new research has shown.

Over time, concrete cracks and crumbles. Well, most concrete cracks and crumbles. Structures built in ancient Rome are still standing, exhibiting remarkable durability despite conditions that would devastate modern concrete. One of these structures is the large cylindrical tomb of first-century noblewoman Caecilia Metella. New research shows that the quality...

Researchers uncover the evolution of the hepatitis B virus since the Early Holocene by analyzing the largest dataset of ancient viral genomes produced to date.

We regularly hear warnings that climate change may lead to 'tipping points': irreversible situations where savanna can quickly change into desert, or the warm gulf stream current can simply stop flowing. But the earth is much more resilient than previously thought. Researchers now show that the concept of tipping points...

Microbiology researchers have shed new light on the mechanisms of carbon cycling in the ocean, using a novel approach to track which microbes are consuming different types of organic carbon produced by common phytoplankton species.

In urban areas across the U.S., low-income neighborhoods and communities of color experience an average of 28% more nitrogen dioxide (NO2) pollution than higher-income and majority-white neighborhoods. The disparity is driven primarily by proximity to trucking routes on major roadways, where diesel trucks are emitters of NO2 and other air...
