The reduction of poverty in India requires much more than solutions such as direct cash transfers.

The global atmospheric circulation transports energy from the equatorial regions to higher latitudes through a poleward flow of high-energy and -entropy parcels and an equatorward flow of air with lower energy and entropy content. Because of its turbulent nature, this circulation can only be described in some averaged sense.

Molecular chlorine (Cl2) is an important yet poorly understood trace constituent of the lower atmosphere. Although a number of mechanisms have been proposed for the conversion of particle-bound chloride (Cl-) to gas-phase Cl2, the detailed processes involved remain uncertain.

Researchers are running out of time to finish updating an important U.S. climate change model that has been hamstrung by the budget woes of its home institution, the National Center for Atmospheric Research.

The development of antibiotic resistance in bacteria has been attributed to the overuse of antimicrobials in human medicine. Another route by which humans are exposed to antibiotics is through the animal foods we eat. In modern agricultural practice, veterinary drugs are being used on a large scale, administered for treating infection or prophylactically to prevent infection.

Scientists have gained new insights in the exact timeline of events that led to the rise of the Tibet plateau, described as the 'roof of the world'. US scientists who pieced together the geological puzzle say the rise of the plateau, due to collision of India with Asia about 50 million years ago, is closely linked to movement of the earth in the Pacific Ocean.

Policies that predict and direct innovative research might seem to be a practical impossibility, says David H. Guston, but social sciences point to a solution.

San Francisco-based Pacific Gas and Electric Company (PG&E) agreed last week to purchase power from two solar-panel manufacturers in the state. OptiSolar, based in Hayward, will build a 550-megawatt plant, to be accompanied by a 250-megawatt plant from SunPower of San Jose.
