In “A New Picture of Dinosaur Nesting Ecology” (Perspective), paleontologist Daniel T. Ksepka offers an overview of these sweeping advances in his field, showcasing the spectrum of reproductive traits among the dinosaurs, often with surprising mixes of reptilian and avian traits.
The cover shows an artist’s impression of Mbiresaurus raathi, a newly discovered species of herbivorous dinosaur found in Zimbabwe and dating to around 230 million years ago.
Joe Biden lands in Saudi Arabia this morning, having spent two unremarkable days in Israel and the West Bank.
As president, he has been unusually disengaged from the Middle East, and will probably return home with little to show for his peregrinations. We survey the state of sex education in Latin American schools, and explain why dinosaurs outcompeted other species.
The Triassic was full of many bizarre creatures and no animal showed this more then Tanystropheus that had a neck that measured the same length as the rest of its body. So where did Tanystropheus come from and why did it have such a long neck?
The chances of mini brains becoming sentient, herd immunity, bat-like dinosaurs, and a UK government decision threatens gender diversity in academia.
In this episode:
00:59 The ethics of creating consciousness
Brain organoids, created by culturing stem cells in a petri dish, are a mainstay of neuroscience research. But as these mini-brains become more complex, is there the chance they could become conscious, and if so, how could we tell?
So called ‘herd immunity’ is claimed by some as a way to break the chain of infection and curtail the pandemic. However epidemiologists say that this course of action is ineffective and will lead to large numbers of infections and deaths.
23:22 How cutting red-tape could harm gender diversity in UK academia
The Athena SWAN scheme, designed to boost gender-equality in UK academia, has proved effective, and has been exported to countries around the world. But now a decision by the UK government to cut bureaucracy could mean that institutions pay less heed to schemes like this and threaten future efforts to increase gender diversity in UK academia.
We discuss some highlights from the Nature Briefing. This time, oncologists discover a potential new human organ, and how re-examined fossils have given new insights into the size of baby tyrannosaurs.
Watch how we installed STAN — one of the most complete T. rex skeletons ever found.
Unearthed in 1987, less than a century after the existence of Tyrannosaurus rex had first become known, STAN — named after his discoverer Stan Sacrison — represents one of the most complete fossil skeletons of the most famous dinosaur species ever to have lived.
Each individual fossil from STAN’s skeleton had to be prised carefully from the rock, then stored and recorded. Following more than 30,000 hours of labour, STAN was erected on a custom mount to reflect his former glory. He was given a public unveiling on Hill City’s Main Street in South Dakota, followed by his global ‘debut’ as the centrepiece of Japan’s T. rex World Exposition in 1995.
