A truffle-eating Australian marsupial known as the “rat kangaroo” has suffered a dramatic population decline and could become extinct without urgent action, a report said yesterday.
Only two populations of the northern bettong remained in the wet coastal tropics of northern Queensland State, numbering at most 2,500, down 70 percent in the past 30 years, the WWF said.
The nocturnal, rabbit-sized bettongs are at risk from feral cats, land-clearing and wildfires, which have become more frequent and fierce in Queensland due to climate change.

“We know particularly with climate change a massive wildfire could be just around the corner,” WWF senior manager for species conservation in Australia Tim Cronin said. “Any situation where you have one population isolated and that’s all you have in the wild, it puts you at a really high risk.”
It is vital to establish an “insurance population” of the northern bettong, protected from pests and fire, and consider raising the species’ status from “endangered” to “critically endangered,” he said.
“It’s not too late for the northern bettong, but our window of opportunity for action is closing fast,” he said.
The northern bettong is one of the main animals that eat truffles, dispersing truffle spores across its habitat and maintaining a delicate ecological balance.
“It plays a really unique role in maintaining ecological function in the vegetation, so if we lose it — and other species like it — we could be looking at ecological collapse,” Cronin said.
Brazil, the world’s largest Roman Catholic country, saw its Catholic population decline further in 2022, while evangelical Christians and those with no religion continued to rise, census data released on Friday by the Brazilian Institute of Geography and Statistics (IBGE) showed. The census indicated that Brazil had 100.2 million Roman Catholics in 2022, accounting for 56.7 percent of the population, down from 65.1 percent or 105.4 million recorded in the 2010 census. Meanwhile, the share of evangelical Christians rose to 26.9 percent last year, up from 21.6 percent in 2010, adding 12 million followers to reach 47.4 million — the highest figure
A Chinese scientist was arrested while arriving in the US at Detroit airport, the second case in days involving the alleged smuggling of biological material, authorities said on Monday. The scientist is accused of shipping biological material months ago to staff at a laboratory at the University of Michigan. The FBI, in a court filing, described it as material related to certain worms and requires a government permit. “The guidelines for importing biological materials into the US for research purposes are stringent, but clear, and actions like this undermine the legitimate work of other visiting scholars,” said John Nowak, who leads field
‘THE RED LINE’: Colombian President Gustavo Petro promised a thorough probe into the attack on the senator, who had announced his presidential bid in March Colombian Senator Miguel Uribe Turbay, a possible candidate in the country’s presidential election next year, was shot and wounded at a campaign rally in Bogota on Saturday, authorities said. His conservative Democratic Center party released a statement calling it “an unacceptable act of violence.” The attack took place in a park in the Fontibon neighborhood when armed assailants shot him from behind, said the right-wing Democratic Center, which was the party of former Colombian president Alvaro Uribe. The men are not related. Images circulating on social media showed Uribe Turbay, 39, covered in blood being held by several people. The Santa Fe Foundation
NUCLEAR WARNING: Elites are carelessly fomenting fear and tensions between nuclear powers, perhaps because they have access to shelters, Tulsi Gabbard said After a trip to Hiroshima, US Director of National Intelligence Tulsi Gabbard on Tuesday warned that “warmongers” were pushing the world to the brink of nuclear war. Gabbard did not specify her concerns. Gabbard posted on social media a video of grisly footage from the world’s first nuclear attack and of her staring reflectively at the Hiroshima Peace Memorial. On Aug. 6, 1945, the US obliterated Hiroshima, killing 140,000 people in the explosion and by the end of the year from the uranium bomb’s effects. Three days later, a US plane dropped a plutonium bomb on Nagasaki, leaving abut 74,000 people dead by the
