This artistic interpretation shows a pack of Nanotyrannus attacking a juvenile Tyrannosaurus rex (front left).Credit: Anthony HutchingsA fossil once assumed to be of a young Tyrannosaurus rex is in fact that of a different species altogether, and the dinosaur it belongs to was a fully grown adult at the time of its death, palaeontologists have found.Facelift for T. rex: analysis suggests teeth were covered by thin lipsThe small tyrannosaur — named Nanotyrannus — is about half the length and one-tenth of the body mass of a fully grown T. rex — which led scientists to initially suspect the fossil belonged…

Credit: sefa ozel/Getty images The molecular mechanism that governs how the glucocorticoid receptor (GR) assembles into higher-order structures inside the cell, a process fundamental to how the receptor regulates gene expression, immune responses, and metabolism, has been uncovered by researchers at the Institute of Biomedicine (IBUB) of the University of Barcelona. The study, published in Nucleic Acids Research, shows that the GR forms tetramers, not just monomers or dimers as previously believed, unlocking a new, potentially fertile, ground for the development of new therapies for a range of conditions. “The glucocorticoid receptor controls approximately 20% of the human transcriptome and…

Cauliflower and sweet butternut squash roast together until caramelized and tender, then get tossed with peppery arugula, tangy goat cheese and crunchy pecans in this salad. Using pre-chopped butternut squash is a great prep time-saver, but if you’d rather start from a whole squash, go for it! Serve it warm or at room temperature for a satisfying side.

Sponsored content brought to you by When developing novel life science products, developers may face challenges in areas such as technical expertise, reagent optimization, manufacturing scale, turnaround time, reagent quality, and comprehensive logistical support. These complexities are particularly magnified within regulated markets. In this Q&A, John Pezza, PhD, Customized Solutions Director at New England Biolabs® (NEB®), and Mike Pelletier, NEB’s Director of Global Operations, discuss the resources and support that companies should expect from a reagents partner to navigate these challenges that come with developing custom products.   Q: What should customers expect from a customized solutions vendor (provider)?

Things are getting spooky!

Nature, Published online: 30 October 2025; doi:10.1038/d41586-025-03561-zA key fossil suggests that the controversial Nanotyrannus is its own species, not a juvenile Tyrannosaurus rex.

The brain contains built-in maps, represented by neurons called place cells.Image credit:© iStock, solarsevenPlace cells are neurons in the brain’s memory center, the hippocampus, that help the brain keep track of the body’s location in space. Arrays of these cells form a cognitive map, firing off electrical signals when the body is in a particular location in its environment. These cells walk a delicate functional tightrope. They have to remain stable so that the brain remembers when the body has re-entered a familiar location, and they have to be ready to adapt as the environment around the body changes. How…

Cyclana Bio lands funding to advance therapeutics for chronic inflammation diseases, starting with endometriosis.  British biotech Cyclana Bio has raised $6.6 million in pre-seed funding to develop next-generation therapies for diseases characterized by chronic inflammation, using cutting-edge tissue modeling technologies that capture how disease behaves in the human body. The Cambridge-based company is initially focused on women’s health, specifically endometriosis, a painful chronic inflammatory condition where womb lining tissue grows outside the uterus. Founded earlier this year by Dr Léa Wenger and Prof. Kevin Chalut, both former scientists at longevity biotech giant Altos Labs, Cyclana aims to close long-standing gaps…
