Ancient DNA reveals the appearance of a 6th century Chinese emperor      (via sciencedaily.com)     Original source 

What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.

Uncovering the mystery of Dorset's Cerne Giant      (via sciencedaily.com)     Original source 

For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.

Persian plateau unveiled as crucial hub for early human migration out of Africa      (via sciencedaily.com)     Original source 

A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.

Researchers name prehistoric amphibian ancestor discovered in Smithsonian collection after Kermit the Frog      (via sciencedaily.com)     Original source 

Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. The team of researchers described the fossil as a new species of proto-amphibian, which they named Kermitops gratus in honor of the iconic Muppet, Kermit the Frog.

New archive of ancient human brains challenges misconceptions of soft tissue preservation      (via sciencedaily.com)     Original source 

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.

Researchers develop a new control method that optimizes autonomous ship navigation      (via sciencedaily.com)     Original source 

Existing ship control systems using Model Predictive Control for Maritime Autonomous Surface Ships (MASS) do not consider the various forces acting on ships in real sea conditions. Addressing this gap, researchers developed a novel time-optimal control method, that accounts for the real wave loads acting on a ship, enabling effective planning and control of MASS at sea.

Satellites for quantum communications      (via sciencedaily.com)     Original source 

Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.

Balancing training data and human knowledge makes AI act more like a scientist      (via sciencedaily.com)     Original source 

When you teach a child how to solve puzzles, you can either let them figure it out through trial and error, or you can guide them with some basic rules and tips. Similarly, incorporating rules and tips into AI training -- such as the laws of physics --could make them more efficient and more reflective of the real world. However, helping the AI assess the value of different rules can be a tricky task.

Lost tombs and quarries rediscovered on British military base in Cyprus      (via sciencedaily.com)     Original source 

Archaeologists rediscovers 46 sites at the Eastern Sovereign Base Area at Dhekelia, Cyprus. Archaeologists located sites from archive records, a number of which were thought to have been 'lost.' They uncovered evidence of quarries and tombs likely to span from the Bronze Age, Byzantine, Hellenistic and Roman periods.

Drawings of mathematical problems predict their resolution      (via sciencedaily.com)     Original source 

Solving arithmetic problems, even simple subtractions, involves mental representations whose influence remains to be clarified. Visualizing these representations would enable us to better understand our reasoning and adapt our teaching methods. A team has now analyzed drawings made by children and adults when solving simple problems. The scientists found that, whatever the age of the participant, the most effective calculation strategies were associated with certain drawing typologies. These results open up new perspectives for the teaching of mathematics.
