Delhi's air quality improves to 'satisfactory'

In two separate incidents Customs officials of Trichy Airport seized gold worth one crore rupees from two male passengers.

Researchers have shown how carbon dioxide from industrial operations or even straight from the air can be gathered and converted into clean, sustainable fuels using just solar energy. The researchers, from the University of Cambridge, developed a solar-powered reactor that converts captured CO2 and plastic waste into sustainable fuels and other valuable chemical products. In tests, CO2 was converted into syngas, a key building block for sustainable liquid fuels, and plastic bottles were converted into glycolic acid, which is widely used in the cosmetics industry.

Plant roots are crucial in the uptake, selection, enrichment, and retention of a variety of mineral elements, which supply distant plant tissues with nutrients and sequesters excess metals. A variety of ion transporters found at roots mediate the absorption, efflux, and intracellular compartmentalization of various mineral elements to carry out such element-specific tasks.

In Physics of Fluids, by AIP Publishing, researchers from the University of California, Los Angeles and Cardiff University in the U.K. developed an early warning system that combines state-of-the-art acoustic technology with artificial intelligence to immediately classify earthquakes and determine potential tsunami risk.

The work was conducted in Del Mar, California, a beach town in San Diego County with infrastructure atop its coastal bluffs.

Oxygen concentration is an important measure of water quality because fish and other aquatic organisms require dissolved oxygen to breathe, according to Wei Zhi, assistant research professor of civil and environmental engineering and first author of the study, recently published in Nature Water.

But a new national study found that housing is also important before disasters happen: People with homes not meeting federal quality classifications and those who are housing insecure tend to be less prepared to face natural calamities.

Certain pesticides, particularly a class called neonicotinoids, are known to impact bees and other important insects, and are thought to be contributing to population declines. However, bees' reported responses to this threat across the world often seem to vary, suggesting other interacting factors are at play.

New research from geophysicists at the University of Leeds suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers at the University of East Anglia. A new study shows the bird's distribution and ecology in Grand Bahama before the hurricane struck.
