Early humans influenced the availability of meat and scavenging animals
A new study indicates that human behavior around 45,000 to 29,000 years ago contributed to a change in the composition of scavenging animal species living nearby. While smaller scavenging animals such as foxes and some bird species benefited from the presence of humans, large scavengers such as hyenas and cave lions tended to be displaced.

International research team measures extreme winds on an exoplanet An international research team led by the University of Göttingen has discovered extremely strong winds on the exoplanet "WASP-127b". The winds along the equator of this planet can reach speeds of up to 33,000 kilometres per hour. These results help better understand the atmosphere of planets outside our solar system.

Extreme climate events endanger groundwater quality and stability, when rain water evades natural purification processes in the soil. This was demonstrated in long-term groundwater analyses using new analytical methods, as described in a recent study in "Nature Communications". As billions of people rely on sufficient and clean groundwater for drinking, understanding the impacts of climate extremes on future water security is crucial.

The fruit fly Drosophila busckii can detect and thrive on toxic food sources The ability to tolerate toxic substances can help animals find new food sources and thrive in certain ecological niches. Researchers at the Max Planck Institute for Chemical Ecology in Jena have now discovered that the fruit fly Drosophila busckii has developed a tolerance to the toxic sulfur compound dimethyldisulfide.

Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. This innovative method, developed by a team of scientists led by Professor Christoph Schneider at the Institute of Organic Chemistry, provides a solution-oriented approach to a long-standing challenge in organic and medicinal chemistry," says Till Friedmann, lead author of It has just been published in the prestigious Journal of the American Chemical Society.

We normally associate high testosterone levels with male dominance and aggression. Among ruffs - a shore bird that breeds across Europe and Asia - some males suffer from too much of it. Together with international colleagues, researchers at the Max Planck Institute for Biological Intelligence have now shown how the birds eliminate the excess: they produce a super enzyme that rapidly breaks down the hormone.

An international team led by Harvard University, ETH Zurich and the University of Zurich has revealed in a new study that trust in scientists is at a moderately high level worldwide. The majority of those surveyed would like researchers to be involved in politics and society. Simone Dohle from the Research Laboratory for Health and Risk Communication (HRCL) helped collect the data for Germany.

Researchers create dataset resource to understand plant development, resilience and biodiversity Land plants are extremely diverse: over 400,000 species reaching every corner of the world. This diversity mainly splits into two plant lineages: vascular and non-vascular. Vascular plants are the ones that often capture our attention - from the towering trees to the crops in our fields.

Global climate models show, how the Arctic permafrost will respond to global warming The Arctic is heating up particularly fast as a result of global warming - with serious consequences. The widespread permafrost in this region, where soils currently store twice as much carbon as the atmosphere, is thawing.

Quantum chemical calculations by HU enable the development of new porous materials distinct by a high adsorption capacity for CO2. Climate experts agree: To tackle the climate crisis, we will not only need to reduce carbon dioxide (CO2) emissions but also directly filter the harmful gas from air and exhaust gases.

For the first time, researchers have observed how HIV penetrates the nuclear pores to the genome of human immune cells Researchers at the Max Planck Institute of Biophysics and the University of Heidelberg have discovered how Hi viruses enter the nucleus of a human cell. The conical protein capsules in which the genetic material of the pathogens is packed accumulate at nuclear pores in human immune cells such as macrophages and pass through them.

Shell-dwelling cichlids take intense care of their offspring, which they raise in abandoned snail shells. A team at the Max Planck Institute for Biological Intelligence used 3D-printed snail shells to find out what happens inside. The young and the mother each follow their own, but synchronized schedules: as soon as the larvae prefer light, they leave the shell on the ninth day after fertilization.

Nitrogen isotopes in Australopithecus tooth enamel show no evidence of meat consumption Pre-humans such as Australopithecus, who lived in southern Africa around 3.5 million years ago, ate little or no meat - this has been proven by Tina Lüdecke and her team at the Max Planck Institute for Chemistry using isotope measurements on fossil teeth.

So-called foraminifera are found in all the world's oceans. Now, an international study led by the University of Hamburg has shown that foraminifera are found in all the world's oceans: The mostly shell-bearing microorganisms absorb phosphate from the water to an unprecedented extent, which pollutes the oceans.

Graphene Made Permeable for Ions
Würzburg chemists have for the first time created a defect in graphene that allows ions to pass through. As they report in 'Nature', this could lead to new applications in water filtration or sensor technology. Graphene is an extremely thin, flexible and resistant material made of pure carbon. It forms layers that consist of virtually a single layer of carbon atoms.
