Indians across the country began celebrating Diwali, the Hindu festival of lights, on Thursday amid concerns over the coronavirus pandemic and rising air pollution.

Diwali is typically celebrated by socializing and exchanging gifts with family and friends. Many light oil lamps or candles to symbolize a victory of light over darkness, and fireworks are set off as part of the celebrations.

Last year, celebrations in India were upended by a renewed spike in COVID-19 infections, but festivities this year seem to be back. Even though the government has asked people to avoid large gatherings, markets have been buzzing ahead of Diwali, with eager crowds buying flowers, lanterns and candles.

As dusk fell on Wednesday, over 900,000 earthen lamps were lit and kept burning for 45 minutes in the northern city of Ayodhya in Uttar Pradesh state, retaining the Guinness World Record it set last year. As part of the Diwali celebrations, the city last year lit 606,569 oil lamps, The Associated Press reported.

The lamps were lit at Ram ki Pauri, at the banks of Saryu River, a stunning spectacle for thousands of visitors who thronged its shores while ignoring coronavirus social distancing norms. A laser and fireworks show followed, illuminating the city's lanes and river banks. Thousands of city residents also lit lamps at their houses and temples.

The festival is being celebrated at a time when India's pandemic crisis has largely subsided.

On Thursday, the country recorded over 12,000 new coronavirus cases and 461 deaths, a far cry from earlier this year when India buckled under a few hundred thousand new infections every day. Overall, it has recorded more than 35 million infections and over 459,000 deaths, according to the Health Ministry. These figures, as elsewhere, are likely undercounts.

Even states where infections were swelling a few weeks ago, such as Kerala along the tropical Malabar Coast, have seen a sustained decline. India also celebrated administering its billionth COVID-19 vaccine dose last month, further boosting confidence that life is returning to normal.

Still, experts have warned that the festival season could bring a renewed spike in infections if COVID-19 health measures aren´t enforced.

There are also worries over air pollution, which typically shrouds northern India under a toxic grey smog at this time as temperatures dip and winter settles in.

On Diwali night, people also lit up the sky with firecrackers - their smoke causing pollution that takes days to clear.

While there is no nationwide ban on bursting firecrackers, a number of states have imposed restrictions to stem the pollution, with some allowing their residents to light green crackers for a certain number of hours. Green crackers produce lesser emissions than normal firecrackers. In the past, similar bans have often been flouted.

A scientist guides a long tube into the mouth and down to the stomach of Thing 1, a two-month-old calf that is part of a research project aiming to prevent cows from burping methane, a potent greenhouse gas.

Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.

While the fossil fuel industry and some natural sources emit methane, cattle farming has become a major climate concern due to the sheer volume of the cows' emissions.

"Almost half of the increase in (global) temperature that we've had so far, it's been because of methane," said Ermias Kebreab, an animal science professor at UC Davis.

Methane, the second largest contributor to climate change after carbon dioxide, breaks down faster than CO2 but is more potent.

"Methane lives in the atmosphere for about 12 years" unlike carbon dioxide which persists for centuries, Kebreab said.

"If you start reducing methane now, we can actually see the effect on the temperature very quickly."

Filho uses the tube to extract liquid from Thing 1's rumen -- the first stomach compartment containing partially digested food.

Using the rumen liquid samples, the scientists are studying the microbes that convert hydrogen into methane, which is not digested by the cow but instead burped out.

A single cow will burp roughly 220 pounds (100 kilograms) of the gas annually.

- 'Social critters' -

Thing 1 and other calves receive a seaweed-supplemented diet to reduce methane production.

Scientists hope to achieve similar results by introducing genetically modified microbes that soak up hydrogen, starving methane-producing bacteria at the source.

However, the team proceeds cautiously.

"We can't just simply cut down methane production by removing" methane-making bacteria, as hydrogen could accumulate to the point of harming the animal, warned Matthias Hess, who runs the UC Davis lab.

"Microbes are kind of social critters. They really like to live together," he said.

"The way they interact and affect each other impacts the overall function of the ecosystem."

Hess's students test different formulas in bioreactors, vessels that reproduce microorganisms' living conditions in a stomach from movements to temperature.

- More productive cows -

The project is being carried out at UC Davis as well as UC Berkeley's Innovative Genomics Institute (IGI).

IGI scientists are trying to identify the right microbe -- the one they hope to genetically alter to supplant methane-producing microbes.

The modified microorganisms will then be tested at UC Davis in the lab and in the animals.

"Not only are we trying to reduce methane emissions, but you also increase the feed efficiency," said Kebreab.

"Hydrogen and methane, they are both energy, and so if you reduce that energy and redirect it to something else... we have a better productivity and lower emissions at the same time."

The ultimate goal is a single-dose treatment administered early in life, since most cattle graze freely and can't receive daily supplements.

The three research teams have been given $70 million and seven years to achieve a breakthrough.

Kebreab has long studied sustainable livestock practices and pushes back against calls to reduce meat consumption to save the planet.

While acknowledging this might work for healthy adults in developed nations, he pointed to countries like Indonesia, where the government is seeking to increase meat and dairy production because 20 percent of children under five suffer from stunted growth.

"We can't tell them to not eat meat," he said.
