With season 2 unfolding, the science of the fungal horror drama is becoming shakier. It is a pity that the creators haven’t thought about terrifying scenarios of real-life infection, says Corrado Nai

In this latest instalment of our speculative column Future Chronicles, an imagined history of future inventions, Rowan Hooper explores the pros (and cons) of networking our brains with those of other animals

Newly discovered species of extinct fish shows striking similarities to unrelated modern-day predators, suggesting certain traits have emerged multiple times and remained consistent over hundreds of millions of years.

Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch typically right next to a gene. This basic form of genomic regulation is probably as old as life on Earth. A new study finds that the ability to control genes from far away, over many tens of thousands of DNA letters, evolved between 650 and 700 million years ago. It probably appeared at the very dawn of animal evolution, around 150 million years earlier than previously thought. The critical innovation likely originated in a sea creature, the common ancestor or all extant animals.

Superb starlings appear to swap between parent and ‘nanny’ roles to help raise chicks over their lifetimes, even when they aren’t related to them

The origin of complex eukaryotic cells, of the type found in all plants and animals, is shrouded in mystery. Now, strange microbes from wetlands in China are helping us to understand when they first emerged, and what they were like

A UK parliamentary committee has greenlit gene-edited plants. This is great news, as it will boost food production and reduce waste, says Michael Le Page

Tyrannosaurus rex evolved in North America, but its direct ancestor came from Asia, crossing a land bridge connecting the continents more than 70 million years ago, according to a new study.

A new study is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered significant variations in a key geological marker, challenging long-standing methods of determining the ages of dinosaur fossils.

Using rock samples collected from the Wasatch Fault, geoscientists combined experiments and analysis with examinations of fault rock textures. The team's research revealed significant clues about the Wasatch Fault's earthquake risk. Researchers explain why properties of fault rocks and geologic events that occurred more than a billion years ago portend worrisome seismic activity for Utah's population center.

Hydrologists show most streamflow out of the West's mountains is old snowmelt on a multi-year underground journey. New study finds that spring runoff is on average 5 years old.

At a conference in Washington D.C. in 2000, the secretoglobin super family of proteins was named to classify proteins with structural similarities to its founding member uteroglobin. Now, 25 years later, there is still little known about the basic functions of these proteins, prompting a group of researchers to dive into their evolutionary origins. This bioinformatic survey reported that secretoglobins, or SCGBs -- originally thought to be exclusive to mammals -- are also found in turtles, crocodilians, lizards, and birds. These new findings suggest that these proteins evolved earlier than dinosaurs and share a basic function that is not yet discovered.

The highest trophic niches in Mesozoic oceans were filled by diverse marine reptiles, including ichthyosaurians, plesiosaurians, and thalattosuchians, dominating food webs during the Jurassic and Early Cretaceous. Yet during the mid-Cretaceous, ichthyosaurs, thalattosuchians, and pliosaurids vanished, replaced by mosasaurs, xenopsarian plesiosaurians, and new groups like sharks, fish, turtles, and birds. This shift restructured marine ecosystems.

While dolphins are known to transmit information in their whistles, until now it hasn't been clear whether the marine mammals used the same sounds to indicate a shared understanding of a concept
