Kashmir valley, nestled in the north-western extremity of Himalayan bio-
diversity hotspot, is bestowed with an incredible plant wealth. However, over the last few decades, flora of the valley faces a multitude of threats. Being historically a global tourist destination, the
In 2004, I visited the Chorabari Glacier on an expedition under the leadership of M. Kuhle. Thus, I have read the paper by R. K. Chaujar with great interest1. In agreement with Chaujar1, we also recognized different latero-frontal moraines around Kedarnath. Because younger glacial history was not the primary aim of our expedition, we did not differentiate
Biogeographical, physiological, and paleoecological evidence suggests that the coast redwood [Sequoia sempervirens (D. Don) Endl.] is closely associated with the presence of summer marine fog along the Pacific coast of California.
Abundant plant biomass has the potential to become a sustainable source of fuels and chemicals. Realizing this potential requires the economical conversion of recalcitrant lignocellulose into useful intermediates, such as sugars. We report a high-yielding chemical process for the hydrolysis of biomass into monosaccharides.
The herbicide atrazine is one of the most commonly applied pesticides in the world. As a result, atrazine is the most commonly detected pesticide contaminant of ground, surface, and drinking water. Atrazine is also a potent endocrine disruptor that is active at low, ecologically relevant concentrations. Previous studies showed that atrazine adversely affects amphibian larval development.
CO2 emissions from the burning of fossil fuels are the primary cause of global warming. Much attention has been focused on the CO2 directly emitted by each country, but relatively little attention has been paid to the amount of emissions associated with the consumption of goods and services in each country.
There is a way of returning to nuclear while overcoming safety and waste concerns: hybrid nuclear fusion. The concept has been around for decades, and has been discussed in the technical literature and at the International Atomic Energy Agency. But it has not yet been explained to governments, industry, researchers and the public.
There is an ongoing debate about the rationality of price controls in a regime where drugs can be manufactured through alternative processes as was the case in India before 2005. In a regime of only process patents, competition was expected to bring prices down.
