Science X Newsletter Week 03

Dear ,

Here is your customized Science X Newsletter for week 03:

	New map shows where damaging earthquakes are most likely to occur in US  Nearly 75% of the U.S. could experience damaging earthquake shaking, according to a recent U.S. Geological Survey-led team of more than 50 scientists and engineers.
	Discovery of second ultra-large structure in distant space further challenges our understanding of the universe The discovery of a second ultra-large structure in the remote universe has further challenged some of the basic assumptions about cosmology.
	Samples from Wild 2 comet reveal a surprising past Eighteen years after NASA's Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus.
	Researchers find evidence of long-lived valley states in bilayer graphene quantum dots In quantum computing, the question as to what physical system and which degrees of freedom within that system may be used to encode quantum bits of information—qubits, in short—is at the heart of many research projects carried out in physics and engineering laboratories.
	Scientists compute with light inside hair-thin optical fiber Scientists at Heriot-Watt University in Edinburgh, Scotland, have found a powerful new way to program optical circuits that are critical to the delivery of future technologies such as unhackable communications networks and ultrafast quantum computers.
	Water molecule discovery contradicts textbook models Textbook models will need to be re-drawn after a team of researchers found that water molecules at the surface of salt water are organized differently than previously thought.
	Searching for dark matter in gaps between stars Although dark matter makes up about 27% of the universe, astronomers have been unable to observe it directly.
	Climate change isn't producing expected increase in atmospheric moisture over dry regions: Study The laws of thermodynamics dictate that a warmer atmosphere can hold more water vapor, but new research has found that atmospheric moisture has not increased as expected over arid and semi-arid regions of the world as the climate has warmed.
	Team uncovers new marine source of carbon emissions into atmosphere Bottom trawling is a previously unaccounted for source of atmospheric carbon emissions, scientists reveal in a study published today. As the world scrambles to slash emissions caused by fossil fuels, deforestation and other sources, the study finds bottom trawling—the act of dragging a heavy fishing net across the ocean floor and resuspending some of the carbon in the seafloor sediment—to be a significant source of atmospheric carbon pollution.
	Who is most efficient in health care? Study finds, surprisingly, it's the VA Private-sector hospitals, clinics, and insurers are bloated, bureaucratic nightmares compared to efficiently run Veterans Health Administration facilities that put care over profits, a new study reveals.
	Insect populations flourish in the restored habitats of solar energy facilities Bumblebees buzz from flower to flower, stopping for a moment under a clear blue Minnesota sky. Birds chirp, and tall grasses blow in the breeze. This isn't a scene from a pristine nature preserve or national park. It is nestled between photovoltaic (PV) solar arrays on rehabilitated farmland.
	Efficiency asymmetry: Scientists report fundamental asymmetry between heating and cooling A new study led by scientists from Spain and Germany has found a fundamental asymmetry showing that heating is consistently faster than cooling, challenging conventional expectations and introducing the concept of "thermal kinematics" to explain this phenomenon. The findings are published in Nature Physics.
	Astrophysicist proposes a new theory of gravity without a conservation law The general theory of relativity is based on the concept of curved space–time. To describe how the energy and momentum of fields are distributed in space–time, as well as how they interact with the gravitational field, a special mathematical construct is used—the energy–momentum tensor. This is a kind of analog of energy and momentum in ordinary mechanics.
	NASA regains contact with mini-helicopter on Mars NASA has re-established contact with its tiny helicopter on Mars, the US space agency said Saturday, after an unexpected outage prompted fears that the hard-working craft had finally met its end.
	Unlocking the magnetic superpowers of topological magnons In the ever-evolving landscape of condensed matter physics, a recent breakthrough has emerged from the collaborative efforts of researchers at the Peter Grünberg Institute (PGI-1), École Polytechnique Fédérale de Lausanne, Paul Scherrer Institut in Switzerland, and the Jülich Centre for Neutron Science (JCNS).
	Shiyu discovery reveals East Asia's advanced material culture dating to 45,000 years ago A team of researchers from China, Australia, France, Spain, and Germany has revealed advanced material culture in East Asia dating to 45,000 years ago. The new study is published in Nature Ecology & Evolution.
	Evidence of one of the largest explosive eruptions ever recorded in the Aegean Sea The Greek archipelago of Santorini consists of the remains of a powerful volcano. Members of the international IODP expedition "Hellenic Arc Volcanic Field" have now found evidence of one of the largest eruptions ever recorded in the southern Aegean Arc.
	Study says ice age could help predict oceans' response to global warming A team of scientists led by a Tulane University oceanographer has found that deposits deep under the ocean floor reveal a way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age, which ended more than 11,000 years ago.
	Study unveils emotional hubs that exist across languages Emotions exert a profound influence on human behavior, prompting extensive explorations in the realms of psychology and linguistics. Understanding central emotions also has practical utility since it can help organizations create messages that resonate better with people. For instance, businesses can enhance their connection with their customers, and non-profits can prompt quicker action by skillfully leveraging the salient emotions in humans.
	The surface knows what lies beneath: Physicists show how to detect higher-order topological insulators Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be "featureless" holds an unmistakable signature that could lead to the first definitive observation.
