Life in the smoke of underwater volcanoes

Deep down in the ocean at tectonic plate boundaries, hot fluids rise from hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as iron, manganese or copper. Some may also transport ...

Shark from the Jurassic period was already highly evolved

Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate ...

Working against the mainstream in fungal systematics

Developments in the current systematics of fungi are largely directed towards the division of existing species into smaller, narrowly defined species. But as demonstrated by scientists from the Faculty of Science, Charles ...

Do dogs really descend from wolves?

Curled up on the sofa, you watch your dog snoozing nearby. Is he dreaming of the bowl of biscuits he gobbled down? Or could he be picturing the great odyssey of his forbearers, who roamed in packs across the vast steppes ...

Multifaceted analysis identifies transitional areas of vegetation as biodiversity hotspots

Climate change and biodiversity loss are interrelated environmental challenges facing the world today, and species living in transitional areas often show adaptive responses to climate change, making such areas crucial for ...

Researchers uncover key codon repeats regulating chilling tolerance in rice

A recent study by Prof. Chong Kang's group from the Institute of Botany of the Chinese Academy of Sciences (CAS) has revealed a novel cold domesticated repair mechanism for DNA damage in rice, providing corresponding elite ...

New metric of molecular evolution in the search for the genetic basis of phenotypic traits

With its powerful digging shovels, the European mole can burrow through the soil with ease. The same applies to the Australian marsupial mole. Although the two animal species live far apart, they have developed similar organs ...

Sharpsnout seabream's mortality during early life stages shown to have genetic base

The high mortality in the early stages of life is a common phenomenon in fish and other species, but it is little studied due to its complexity. A study by the University of Barcelona and the Center for Advanced Studies of ...

Study sheds light on phylogenomics and tree of life of flowering plants

Flowering plants (angiosperms) are the largest, most diversified, and most successful major lineage of green plants, with ~330,000 known species. In the past decade, the accelerated development of high-throughput sequencing ...

More than 52 million birds in the US have been affected by an outbreak of avian influenza

A form of highly pathogenic avian influenza (HPAI) has been causing widespread disruption and illness in birds since first being detected roughly a year ago. Last March, a bald eagle found dead in Pennsylvania's Chester County ...
