Twenty-eight paintings by Johannes Vermeer go on display at the Rijksmuseum in Amsterdam this week, the largest ever exhibition of works of the 17th-century Dutch master, known for his expertise at rendering light and intimate household scenes.

The show gathers half the works that Vermeer, who died aged 43 and worked slowly, is thought ever to have painted and three-quarters of those that still exist. He likely never saw so many of his own works together at one time.

Rijksmuseum director Taco Dibbits said Vermeer was a man who lived with a large family and had a busy life as an art dealer, but still managed to obsessively refine works of quiet beauty, bathed in light rendered with almost photographic accuracy.

"It's this ... complete focus and tranquility in his paintings that we still love today," Dibbits said.

Alongside famed works like "Girl With A Pearl Earring" (1664) and "The Milkmaid" (1659), the exhibit features Vermeer's two known outdoor paintings, several large canvases, and a string of his portrayals of women -- including playing instruments, reading and working.

"What's quite striking when you look at Vermeer is that in his paintings, it's mostly women who are the protagonists," said curator Pieter Roelofs, noting Vermeer had seven daughters.

Though no letter written by Vermeer exists, a key document is an inventory of possessions drawn up after his death, which left the family in debt. Furniture and many objects mentioned on the list appear in the paintings.

Roelofs said major advances have been made in understanding how Vermeer worked, including identifying pinholes at the focal point in some paintings such as "The Milkmaid", part of a system of strings he used to help ensure perfect perspective.

Artists and scholars dispute whether Vermeer may have made use of a "camera obscura", a forerunner of the modern photocamera.

Roelofs said Vermeer's works are more than something a good eye and skilled hand can create. Recent analysis shows the composition of "The Milkmaid" changed several times, notably by stripping things out to simplify it.

"That is what Vermeer is: it's never good enough and he keeps working on it until he thinks its sufficient to hand over to clients," Roelofs said.

Author Tracy Chevalier, whose novel "Girl with a Pearl Earring" was adapted to a movie of the same name, said for her the exhibition evoked an image of Vermeer as a reserved man who "plays his cards close to his chest."

"His paintings are so quiet and there are no children ... he must have compartmentalized his life and said 'no, no kids in the studio'."

Museums in Germany, France, Japan, Britain, Ireland and the United States contributed to the exhibition, which opens on Friday and runs until June.

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.
