What to read this week: the persuasive How Flowers Made Our World
We shouldn't dismiss flowers as merely ornamental – these blooms are world-changers, argues a vivid new book by David George Haskell
What would it take to prepare the NHS for a war?
As the threat of war looms larger, experts warn that the UK must start planning now to scale up military evacuations, recruit retired medics and protect hospitals from attack
Genetic clues tell the story of Neanderthals' decline
The Neanderthal population shrank during a cold spell around 75,000 years ago, and the loss of genetic diversity may have contributed to their eventual extinction
Deep time journeys: A cross-continental look at early human archaeology
This program transports participants to four of the world’s most revealing prehistoric landscapes - Morocco, the Neanderthal heartlands of France, northern Spain, and Turkey
Neanderthals may have treated wounds with antibiotic sticky tar
Tar made from birch tree bark is commonly found at Neanderthal sites, and experiments show that it kills some bacteria that cause skin infections
The ancient Goths were an ethnically diverse group
Ancient DNA reveals that the Goths of eastern Europe, some of whom would ultimately sack the city of Rome, may have been a mix of peoples from three continents
Our extinct Australopithecus relatives may have had difficult births
Simulations of Australopithecus hominins’ anatomy suggest that when they gave birth, they may have exerted tremendous pressure on their pelvic floors, putting them at risk of tearing
We’ve only just confirmed that Homo habilis really existed
Their species name is well known, but until recently we’ve understood very little for certain about Homo habilis
The first apes to walk upright may have evolved in Europe
A single femur found in Bulgaria appears to represent an ape or early hominin that walked on two legs before any known African hominin, but the evidence is far from conclusive
Ancient 'weirdo' reptile graduated from 4 legs to 2 in adolescence
Sonselasuchus cedrus, discovered in fossils from Arizona, was a crocodile relative from the Triassic period that grew into an ostrich-like adult
The secret of how cats twist in mid-air to land on their feet
An exceptionally flexible region of the spine enables falling cats to twist the front and back halves of their body sequentially to ensure a safe landing
Top predators still prowled the seas after the biggest mass extinction
The end-Permian extinction 252 million years ago wiped out over 80 per cent of marine species, but many ecosystems still had complex food webs despite the losses
Six things every doctor needs to know about AI scribes
Use of AI-based ambient listening tools is rising sharply in medicine, but research on their benefits and training about best practice are still sparse
When we interbred with Neanderthals, they were usually the fathers
Genetic evidence hints that there was a strong bias for male Neanderthals and female humans to mate, rather than any other combination
Snowball Earth might have had a dynamic climate and open seas
Rocks from a global ice age over 600 million years ago show records of an active climate
