But Lauren Groff has reimagined the life of 12th-century poet Marie de France so that we can’t help but stay with this royal castoff as she’s sent away, at 17, to run a poor church, which she eventually changes into a shelter fo...
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
This study introduces the term ferroptosis to describe a novel form of non-apoptotic cell death and identifies the small molecule ferrostatin 1 as the first specific inhibitor of ferroptosis. Article CAS Google Scholar Ganz, T. Systemic iron homeostasis. Physiol. Rev. 93, 1721–1741 (2013). ...
This means that, although major earthquakes and great volcanic eruptions can also occur during the sunspot number ascending and maximum phase, but, from a long-term statistical perspective, the probability of occurrences of the major earthquakes and great volcanic eruptions occurring during the sunspot...
Having forged the idea that the world is a global community of shared future, and believing that it must act as a responsible member, China has fought shoulder to shoulder with the rest of the world. In an open, transparent, and responsible manner and in accordance with the law, China ...
oxygen atom is functioning as both an electromagnetic force-mediating structure and a matter-energy exchanging tunnel simultaneously. For instance, in the case of an iron oxide molecular system, the two iron atoms and the three oxygen atoms are collectively performing the quantum-physical activities ...
Fill in the blank with the appropriate term. Water is essentially neutral, with a pH of ___. pH in chemistry In chemistry, the pH is a measurement of the concentration of hydrogen ions in a particular solution. This measures how acidic, basic or neutral a solution is....
Under climate warming, the cryosphere, defined as the part of Earth’s layer characterized by the low temperatures and the presence of frozen water, has been experiencing significant changes. The Arctic cryosphere (e.g., sea ice, snow cover, Greenland ice sheet, permafrost) can store and ...
where some satellites orbit, particularly those designed for long-term observations of Earth or communications. The low density of particles in this layer means that there is minimal drag on these satellites, allowing them to maintain their orbits for extended periods with little need for adjustment...
