What’s in a name? (Hindu)

Far from hubris, Anthropocene is a formal acknowledgement of guilt about what we have to done to the earth

Last year, the International Commission on Stratigraphy (ICS) — the body that decides epochs, aeons and eras to mark the earth’s geological history — recommended that humans should have their own epoch. Anthropocene, as this proposed epoch is called, roughly means the ‘Recent Age of Man’ and was first proposed by Nobel laureate Paul Crutzen and atmospheric scientist Eugene Stoermer around 2000.

Today we live in the Holocene, a period that began roughly 12,000 years ago. This corresponds to the beginning of agriculture, the earliest settlements in West Asia, and the multiplication of humanity to every part of the globe. Geologists mark out an age based on imprints in fossil records. They have never marked out an age as belonging to an organism or species. ‘Jurassic’, for instance, has nothing to do with dinosaurs and refers to the Jura mountains in Europe.

Is Anthropocene man’s self-attestation that he is the master of the universe?

If the planet were to end
Far from hubris, Anthropocene is a formal acknowledgement of guilt. The triumphant march of Homo sapiens, chronicled through the ages as ‘civilization’, has over the past half a century begun to be replaced by a creeping shame: there is concrete enough to cover every square kilometre of the earth, ginormous amounts of plastic that outweigh this planet’s seven-billion inhabitants, and warheads primed to destroy all traces of the years it took to conceive them.

Armageddon is no longer the scary chapter that concludes religious texts but is now staid science. Of course, the details are hazy and many years away, but in broad terms there is fair agreement that life — organic life at least — is three-fourths done and earth is almost halfway through its journey of being destroyed by the sun. This is even if mankind stops, as of this second, every wisp of its greenhouse gases.

When the leaders of the world congregated and congratulated themselves in Paris about their success in getting everyone to agree (without any binding commitments) that the earth couldn’t be allowed to heat up two degrees, it only showed how naively humanity hopes that somehow technology and evolution will ‘save’ us. The lesson for doomsday scenarios is that survival must involve a massive upheaval in the way we conceive of our place on earth and how squabbles over apportioning carbon emissions are pointlessly incremental and futile when what we need is radical — almost outrageous — ideas for even a moon shot at surviving, let alone as a species.

In this light, the quest for Anthropocene is man scratching out a timestamp in the sand, not to show that we lived but just that we existed.

What's ailing Namami Gange programme?(DTE)

Winters are extremely hectic for Sushma Patel, a vegetable grower in Uttar Pradesh’s Chunar town. Her farm is in the fertile plains of Ganga where people grow three crops a year. But this is the only season when she can grow vegetables. And before that, she needs to manually dig out shreds of plastic and wrappers from her one-hectare (ha) farm. “This is all because of the nullah,” she says, pointing at an open drain that runs through her field, carrying sewage from the neighbourhood to the Ganga. “Every monsoon, the drain overflows and inundates the field with a thick, black sludge and plastic debris. We cannot even go near the field as the stench of sewage fills the air,” she says. But Patel has no one to complain to as this is the way of life for most people in this ancient town. About 70 per cent of the people in Chunar depend on toilets that have on-site sanitation, such as septic tanks and pits. In the absence of a proper disposal or management system, people simply dump the faec...

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...
