The poisonous birds inhabit one of Earth’s most pristine rainforests, a place as exotic as no other in the world. Hearing the words poisonous and bird coupled will be an eye-opener for most. But poisonous birds actually exist. And now, more species have been discovered in New Guinea’s jungles. "We managed to identify two new species of poisonous birds on our most recent trip. These birds contain a neurotoxin that they can both tolerate and store in their feathers," says Knud Jønsson of the Natural History Museum of Denmark. Jønsson and fellow UCPH researcher, Kasun ...

Antarctic sea ice is an important component of the climate system, and may act as an early indicator of climate change. Under global warming, significant changes in Antarctic sea ice have been observed. Specifically, it experienced a slow increase during 1979–2014, but a rapid decline thereafter. Despite a modest recovery after the record minimum in 2017, the sea ice area during austral summer 2022 (December 2021 to February 2022) again hit a new record minimum, at 3.07 million km2, which is approximately a 25% reduction compared with its long-term mean during 1981–2010. The largest decline occurred in two regions: the central-eastern Ross Sea ...

Manganese oxides are natural reactive minerals and widely spread in aquatic and terrestrial environments, affecting the fate of metals (such as As3+ and Cd2+) and organic pollutants (such as phenols and diclofenac) through adsorption and oxidation in sewage treatment. Usually, the manganese (III/IV) oxides in the environment are thought to be formed by the oxidation of dissolved Mn(II) through abiotic or biotic processes. Oxidation of aqueous Mn(II) by dissolved oxygen is thermodynamically favored, but the kinetic is slow due to the high energy barrier of the reaction from dissolved ...

End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by environmental physicist Prof. Dr André Butz of Heidelberg University. To investigate the carbon fluxes over Australia, the researchers studied atmospheric CO2 measurements. Their analyses show that CO2 emissions spike when heavy rain falls on dried-out soil, thus activating microorganisms in that soil. The findings suggest that dry regions have a greater influence on the variations in the global carbon cycle than previously thought. The Australian continent is dominated by dry ecosystems and widely varying precipitation patterns. ...

Ants are pretty much everywhere. There are more than 14,000 different species, spread over every continent except Antarctica, and researchers have estimated that there are more than four quadrillion individual ants on Earth-- that’s 4,000,000,000,000,000. But how ants evolved to take over the world is still a mystery. In a new study in the journal Evolution Letters, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and ...
