Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 21:

	Lost since 1362: Researchers discover the church of a sunken medieval trading place The medieval trading center of Rungholt, which is today located in the UNESCO Wadden Sea World Heritage Site and currently the focus of interdisciplinary research, drowned in a storm surge in 1362.
	Researchers discover Chinmo, 'the youth gene' A new study published on eLife and led by the Institute for Evolutionary Biology (IBE, CSIC-UPF) and the IRB Barcelona, has revealed that the Chinmo gene is responsible for establishing the juvenile stage in insects. It also confirms that the Br-C and E93 genes play a regulatory role in insect maturity. These genes, which are also present in humans, act as a promoter and as a suppressor, respectively, of cancerous processes.
	Unidentified aerial phenomena observations reported by almost one fifth of academic survey respondents Nineteen percent of respondents to a survey of academics report that they or someone they know have witnessed unidentified aerial phenomena (UAP)—observations of the sky that cannot be identified as aircraft or as known natural phenomena—and 37% report some degree of interest in conducting research into UAP.
	Engineers harvest abundant clean energy from thin air, 24/7 A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter. The research appeared in the journal Advanced Materials.
	Machine learning approach opens insights into an entire class of materials being pursued for solid-state batteries A team of researchers at Duke University and their collaborators have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters.
	The laws of physics have not always been symmetric, which may explain why you exist For generations, physicists were sure the laws of physics were perfectly symmetric. Until they weren't.
	Calculating the amount companies owe for causing global warming A pair of sociologists, one with the University of Milan-Bicocca, the other with the Climate Accountability Institute, has used survey data to calculate the amount companies should be paying in reparations to compensate for activities that have led to global warming.
	Experiments see first evidence of a rare Higgs boson decay The discovery of the Higgs boson at CERN's Large Hadron Collider (LHC) in 2012 marked a significant milestone in particle physics. Since then, the ATLAS and CMS collaborations have been diligently investigating the properties of this unique particle and searching to establish the different ways in which it is produced and decays into other particles.
	Breed, age and puppyhood socialization linked to canine personality The dog, man's best friend, is a popular pet. There are hundreds of different dog breeds, each of which is said to have a personality of their own. A study recently completed at the University of Helsinki confirms this notion of personality differences between dog breeds. The research is published in the journal iScience.
	Despite the dangers, early humans risked life-threatening flintknapping injuries Every day, hundreds of stone artifact enthusiasts around the world sit down and begin striking a stone with special tools attempting to craft the perfect arrowhead or knife. This craft is known as flintknapping, and for most, it is a skilled hobby or art form that was thought to occasionally require bandages or stitches.
	Saddle unearthed in China may be oldest ever found An international team of archaeologists has found what may be the earliest known saddle at a dig site in China. In their paper published in the journal Archaeological Research in Asia, the group describes where the ancient saddle was found, its condition and how it was made.
	White-bellied pangolins have second-highest number of chromosomes among mammals There's a lot scientists don't know about the pangolin—a peculiar, scaly mammal that looks like a cross between an aardvark and an armadillo. Now, a new paper published in the journal Chromosome Research reveals what UCLA researcher Jen Tinsman calls a "scientific surprise" that underscores how unusual the animal is.
	Marsupials might be the more evolved mammals Mammal evolution has been flipped on its head, according to new research that suggests marsupials are the more evolved mammals.
	Researchers reveal that the mechanism for forming colloidal gels differs from glass formation The soft, solid-like properties of colloidal gels are essential in fields such as food and medical applications, but how these properties manifest themselves is a long-standing mystery. Until now, it was believed that the solid nature of gels emerges through glass formation.
	World's most sensitive model-independent experiment starts searching for dark matter The world's most sensitive model-independent experiment to search for particularly light particles, of which dark matter might be composed, starts today at DESY in the form of the 'light shining through a wall' experiment ALPS II. Scientific calculations predict that this ominous form of matter should occur five times as often in the universe as normal, visible matter. Until now, however, no one has been able to identify particles of this substance; the ALPS experiment could now furnish such evidence.
	Danish researcher and NASA predict how many people will die from air pollution in the future They come from factory stacks, car exhaust pipes and cruise liner engines. They are tiny particles and they are all around us. When we breathe in air, these particles settle in the small vessels of our lungs, and they make us sick.
	Stable qubit is a prime candidate for universal quantum computer Researchers from QuTech improved the so-called "Andreev spin qubit" in a critical way and believe it can become a prime candidate in the pursuit of a perfect qubit. The new type of qubit is created in a more reliable and intrinsically stable way, compared to previous versions, by combining the advantages of two other types of qubits. The team has published their work in Nature Physics.
	Element creation in the lab deepens understanding of surface explosions on neutron stars Led by Kelly Chipps of the Department of Energy's Oak Ridge National Laboratory, scientists working in the lab have produced a signature nuclear reaction that occurs on the surface of a neutron star gobbling mass from a companion star. Their achievement improves understanding of stellar processes generating diverse nuclear isotopes.
	Fossil tells the 'tail' of an ancient beast Approximately 200 million years ago, Antarctica was attached to South America, Africa, India, and Australia in a single "supercontinent" called Gondwana. Paleontologists have long wondered about the unique mammals that lived only on this ancient supercontinent, including a particularly elusive group called Gondwanatheria, for which few fossils have been identified.
	Stephen Hawking's last collaborator on physicist's final theory When Thomas Hertog was first summoned to Stephen Hawking's office in the late 1990s, there was an instant connection between the young Belgian researcher and the legendary British theoretical physicist.
