Molecular shape-shifting      (via sciencedaily.com) 

Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists revealed this mechanism which may be used to actively manipulate molecular organization. A seed of the novel desired configuration is sufficient to trigger reorganization. This principle can be applied on to biological building blocks which are constantly recycled to form new structures in living systems.

True giant wombat gives Diprotodon podium a wobble      (via sciencedaily.com) 

While the Diprotodon -- the extinct megafauna species that is distantly related to wombats but was the size of a small car -- is commonly (but incorrectly) thought of as Australia's 'giant wombat', researchers have shed light on a large species that does belong in the modern-day wombat family. The complete skull of this true fossil giant wombat, found in a Rockhampton cave in Queensland, Australia and estimated to be around 80,000 years old, has been described for the first time.

Bolstering the safety of self-driving cars with a deep learning-based object detection system      (via sciencedaily.com) 

Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.

Dinosaur teeth reveal what they didn't eat      (via sciencedaily.com) 

Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of marks scratched into them, researchers could reason which dinosaurs may have frequently crunched on hard bone and which may have regularly eaten softer foods and prey. This technique opens up a new avenue of research for paleontology, helping us to better understand not only dinosaurs themselves but also the environment and communities in which they lived.

Discovery of world's oldest DNA breaks record by one million years      (via sciencedaily.com) 

Two-million-year-old DNA has been identified -- opening a 'game-changing' new chapter in the history of evolution. Microscopic fragments of environmental DNA were found in Ice Age sediment in northern Greenland. Using cutting-edge technology, researchers discovered the fragments are one million years older than the previous record for DNA sampled from a Siberian mammoth bone. The ancient DNA has been used to map a two-million-year-old ecosystem which weathered extreme climate change.

Dinosaurs were on the up before asteroid downfall      (via sciencedaily.com) 

Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into dinosaurs' ecosystems -- the habitats and food types that supported their lives -- suggests that their environments were robust and thriving, right up until that fateful day, at the end of the Cretaceous period.

Meteorites plus gamma rays could have given Earth the building blocks for life      (via sciencedaily.com) 

Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids -- life's building blocks -- to our planet. Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.

Ankylosaurs battled each other as much as they fought off T. rex      (via sciencedaily.com) 

Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates.
