A pair of researchers from the Universities of California and Drew, believe they may have solved the mystery of why people living during the time of the Roman Empire used lopsided dice in their games.

During the time of the Roman Empire, people played a game called taberna (similar to backgammon), which involved throwing dice. The dice were made out of bone, metal or clay and had symbols shown on the faces to represent numbers, as with modern dice. But they differed markedly in shape. The Roman dice were usually elongated or made into other odd shapes that made them asymmetrical.

In their paper published in the journal Archaeological and Anthropological Sciences, the researchers studied 28 dice from the period and found that 24 of them were asymmetrical. They found a pattern in the irregularity - icons representing one and six were often present on larger opposing surfaces.

Prior research has shown that asymmetry in a die can impact the probability of a given side landing face up. To find out if the Romans made their dice asymmetrical as a means of cheating, the researchers conducted an experiment - they asked 23 students to place marks on reproductions of the asymmetrical Roman dice.

The researchers reasoned that because the students would not know the purpose of the experiment and had no incentive to cheat, they would mostly place the marks randomly. But that was not the case, the students still placed the one and six on the larger sides.

When asked why, many suggested it was easier because starting on a large side meant ending on a large side where they would need to place the most pips - a finding that suggests the Romans were not trying to cheat, but just trying to make life easier for themselves.

Manufacturers and users understood that dice throwing was governed by the fates, not by chances, so the irregular forms were tolerated as an acceptable range of asymmetry.



'Lungs of the Earth': the Indonesians Fighting for Peatland

'Lungs of the Earth': the Indonesians Fighting for Peatland

Indonesian environmentalist Pralensa steered his boat through a shallow canal in the marshy peatlands near his village, an environment he fears may soon disappear.

His oar stirred up rich organic material in the brackish water, evidence of the layers of plant matter that make peatlands vital carbon dioxide stores and key to biodiversity, AFP said.

Indonesia has more tropical peatland than any other country, but it is also quickly losing this poorly understood ecosystem.

That affects local residents and wildlife but also has global impacts, because converted peatland can release vast quantities of planet-warming carbon dioxide.

Pralensa worries a similar fate awaits much of the swampy peatland around his village of Lebung Itam in South Sumatra.

Locals say palm oil firm Bintang Harapan Palma has already begun digging canals to drain the peatlands for planting.

"We protested... we told them this is a community-managed area," said Pralensa, who, like many Indonesians, uses a single name.

"According to them, they already have rights to this land."

Bintang Harapan Palma did not respond to AFP's request for comment.

Peatlands are an in-between place -- seemingly neither water nor land -- an environment that slows plant decomposition and forms carbon-rich peat.

Covering just three percent of the world's surface, they hold an estimated 44 percent of all soil carbon.

Indonesia's peatlands are home to endangered orangutans, as well as economically important fish species. They also help prevent flooding and drought, lower local temperatures and minimize saltwater intrusion.

For Pralensa, peatlands are no less than a "spiritual bond".

"From the moment that we exist, that we're born, we are aware of this peatland. We encounter it every moment of every day," the 44-year-old said.

Catastrophic fires

Indonesia's peatland has long been converted for agriculture, drained of the water that is its lifeblood, with severe consequences.

Dry peat is highly flammable, and fire can smoulder underground and reignite seemingly at will.

The blazes sparked calls for action, including a moratorium on new peatland concessions.

Government regulations adopted the following year banned several damaging activities, including burning and drying out peatland.

The environment ministry did not respond to questions submitted by AFP.

"Weak oversight and law enforcement in Indonesia allow the exploitation of peatlands to continue," said Wahyu Perdana at peatland preservation NGO Pantau Gambut.

And fires still happen "almost every year," said Rohman, a farmer in Bangsal village, around two hours west of Lebung Itam.

Like Lebung Itam, it is ringed by plantations on converted peatland.

Bangsal residents could once rely on vast wetlands to feed their distinctive buffalo, which dive beneath the water to graze.

Fish traps supplied additional income, along with small rice paddies.

'We must protect nature'

Plantation infrastructure prevents water from subsiding properly when the rains end, complicating rice planting.

And then there is the seasonal haze.

"It's difficult to do anything" when it descends, said Rohman, with visibility sometimes dropping to just a few meters.

Everything from "economic activity to children playing and learning is very disrupted".

Rohman, 53, was one of several plaintiffs from Bangsal and Lebung Itam who filed a landmark lawsuit over the fires.

They argued three companies with nearby timber plantations on peatland bore legal responsibility for the health, economic and social impacts of local fires.

Filing the suit was not an easy decision, said Bangsal schoolteacher Marda Ellius, who alleges a company named in the case offered her money and help for her family if she withdrew.

"I kept thinking that, from the beginning, my goal here was for the environment, for many people," she said.

"I chose to continue."

AFP could not reach the companies named in the suit. Major firm Asia Pulp & Paper (APP), which buys from the three companies, did not respond.

This month, a local court rejected the suit, saying the plaintiffs lacked standing.

"The pain cannot be described," plaintiff Muhammad Awal Gunadi said of the ruling.

"It was tough because we were facing corporations.

The group has pledged to appeal, and Bangsal's villagers are lobbying local government for a new designation to protect their remaining peatland.

Healthy peat is "like the lungs of the Earth," said Bangsal resident and buffalo farmer Muhammad Husin.

"Hopefully, if we protect nature, nature will also protect us."
