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.

Primordial germ cells made from northern white rhino stem cells      (via sciencedaily.com) 

In its race to advance assisted reproduction and stem cell associated technologies to save the northern white rhinoceros from extinction, researchers announce a major breakthrough: the creation of primordial germ cell-like cells (PGCLSs) from induced pluripotent stem cells of the northern white rhino Nabire. Now there is one last step to master for the production of artificial rhino gametes (eggs and sperm) from preserved tissue. If successful, this would boost the availability and genetic diversity of embryos and become a cornerstone for saving the northern white rhinoceros.

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.

Mammoth problem with extinction timeline      (via sciencedaily.com)     Original source 

Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.

Microlaser chip adds new dimensions to quantum communication      (via sciencedaily.com) 

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional microlaser generates 'qudits,' photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications.

The way you talk to your child about math matters      (via sciencedaily.com) 

'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.

A key role for quantum entanglement      (via sciencedaily.com) 

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.
