Current Antarctic conservation efforts are insufficient to avoid biodiversity declines, study shows      (via sciencedaily.com) 

Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a new study.

Is there a link between climate change and plant nutrition?      (via sciencedaily.com) 

A new study underscores that we still have much to learn regarding how plants will function -- and how nutritious they will be -- as more carbon enters our atmosphere. That same influx of carbon is helping drive climate change, meaning this new work may be revealing an unexpected way this global phenomenon is reshaping nature and our lives.

Decoding the secret language of photosynthesis      (via sciencedaily.com) 

For decades, scientists have been stumped by the signals plants send themselves to initiate photosynthesis, the process of turning sunlight into sugars. Researchers have now decoded those previously opaque signals.

Human activities degrade hippopotamus homes at Bui National Park, Ghana, researchers find      (via sciencedaily.com) 

Researchers found that the number of common hippopotamus in the Bui National Park declined by about 70 percent following the construction of a hydroelectric dam in the reserve. From 209 individuals before the dam construction, the number declined to 64. Land cover changes led to severe reduction in forest cover and destruction of riparian areas through flooding. In addition, poaching activities increased during and after the construction period.

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.

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.

New method to systematically find optimal quantum operation sequences for quantum computers developed      (via sciencedaily.com) 

Computer scientists have succeeded in developing a method for systematically finding the optimal quantum operation sequence for a quantum computer. They have developed a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences. This method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.
