Rockcress for heavy-metal clean up

Rockcress of the Arabidopsis halleri species is known to possess the capability of settling on hostile, heavy metal-contaminated soil. It stores extraordinary high concentrations of certain toxic heavy metals in its leaves: a rare property. Researchers have analyzed approx. 2,000 specimens of this species from 165 locations throughout Europe. In this process, they identified overwhelming diversity that has arisen among plants of the same species over the course of evolution. Their findings help explore plants’ enormous potential for future technologies; in this case, they aid the detoxification of soil and the extraction of metals that are of economic interest. 

Small-scale agriculture threatens the rainforest

An extensive study has mapped the effects of small farmers on the rain forests of Southeast Asia for the first time. The findings are discouraging, with regard to environmental impact, biodiversity and the economy, over the long term.

Plant discovered that neither photosynthesizes nor blooms

A new species of plant has been discovered on the subtropical Japanese island of Kuroshima (located off the southern coast of Kyushu in Kagoshima prefecture) and named it Gastrodia kuroshimensis. The new flowering plant species is a very rare event as the flora of this region have been thoroughly investigated. However, G. kuroshimensis was a particularly special discovery because it is both completely mycoheterophic, deriving its nutrition not from photosynthesis but from host fungi, and completely cleistogamous, producing flowers that never bloom.

Diversified management provides multiple benefits in boreal forests

Forests provide multiple social and environmental benefits and play a key role in bioeconomy particularly in the Nordic countries. For example, the Finnish bioeconomy strategy aims to considerably increase the use of forest-based biomasses and forest harvesting by 2025. However, new research shows that there are strong conflicts between intensive timber harvesting and the provision of other benefits or the maintenance of biodiversity.

Wind patterns in lowest layers of supercell storms key to predicting tornadoes

Wind patterns in the lowest 500 meters of the atmosphere near supercell thunderstorms can help predict whether that storm will generate a tornado, report investigators.

What’s that? New study finds jumping spiders can hear more than you think

While jumping spiders are known to have great vision, a new study proves for the first time that spiders can hear at a distance. A study describes how researchers used metal microelectrodes in a jumping spider’s poppy-seed-sized brain to show that auditory neurons can sense far-field sounds, at distances up to 3 meters, or about 600 spider body lengths.

Extraterrestrial impact preceded ancient global warming event

A comet strike may have triggered the Paleocene-Eocene Thermal Maximum (PETM), a rapid warming of Earth caused by an accumulation of atmospheric carbon dioxide 56 million years ago, which offers analogs to global warming today.

Drivers of evolution hidden in plain sight

The evolutionary history of thousands of protein modifications in 18 related species have now been reconstructed by a team of scientists. Their findings highlight a previously unknown strategy for generating the diversity needed for natural selection.

Oldest known squawk box suggests dinosaurs likely did not sing

The oldest known vocal organ of a bird has been found in an Antarctic fossil of a relative of ducks and geese that lived more than 66 million years ago during the age of dinosaurs.
