“#Supply constraint from earthquakes in Japan in input-output analysis” Direct damage of a disaster and indirect damage among sectors in a supply chain of five sectors (as an example) Credit: John Wiley and Sons Many people can recall shocking news images of Japan sustaining earthquake damage. Between 1996 and September of 2018, there were 155…
“#’Ironing’ out the differences: Understanding superconductivity in ultrathin FeSe” The results show that resistivity begins to decrease sharply at temperatures below 40 K regardless of the thickness of the FeSe layer. This means that two-dimensional superconductivity in FeSe/STO occurs at the interface rather than across all FeSe layers. ρ2D: two-dimensional resistivity, UC: unit-cell thickness. Credit:…
“#Transgenic rice lowers blood pressure of hypertensive rats” Credit: American Chemical Society In the future, taking your blood pressure medication could be as simple as eating a spoonful of rice. This “treatment” could also have fewer side effects than current blood pressure medicines. As a first step, researchers reporting in ACS’ Journal of Agricultural and…
“#New research reveals how water in the deep Earth triggers earthquakes and tsunamis” Quill, on the island of Statia. One of the islands in the Lesser Antilles. Credit: Dr George Cooper In a new study, published in the journal Nature, an international team of scientists provide the first conclusive evidence directly linking deep Earth’s water…
“#Neptune-sized planet discovered orbiting young, nearby star” Illustration of AU Mic b orbiting its parent star, AU Mic. Credit: NASA’s Goddard Space Flight Center/Chris Smith (USRA) New research published today in Nature reports the discovery of a planet about the size of Neptune orbiting an especially young, nearby star. The planet, named AU Mic b,…
“#Four new species of giant single-celled organisms discovered on Pacific seafloor” A specimen of Abyssalia, a new genus of sponges. Credit: Slim Chraiti, University of Geneva. Two new genera and four new species of giant, single-celled xenophyophores (protozoans belonging to a group called the foraminifera) were discovered in the deep Pacific Ocean during a joint…
“#Ion conducting polymer crucial to improving neuromorphic devices” Photograph of a neuromorphic device used in this study. Credit: Shunsuke Yamamoto “Neuromorphic” refers to mimicking the behavior of brain neural cells. When one speaks of neuromorphic computers, they are talking about making computers think and process more like human brains-operating at high-speed with low energy consumption….
“#Unearthing evidence of more sophisticated manufacturing in the bronze age” Type of bone and antler tools found at the site. Including a) a possible loom shuttle made of antler, b) a possible spindle made of antler, c) a whorl made of bone, d—g) bone awls and perforators, i) a small (broken) shearing comb made of…
“#ESA listens in on black hole mission” Illustration of the Spektr-RG spacecraft. Credit: NPO Lavochkin European and Russian specialists recently worked together to catch signals from an astrophysical observatory mission, now mapping X-ray sources in our galaxy and beyond, discovering previously unknown supermassive black holes. In a joint technology demonstration conducted in April and May,…
“#Dynamical and allosteric regulation of photoprotection in light harvesting complex II” Credit: CC0 Public Domain The photosynthetic systems of green plants have developed a dual function of efficient light collection under low light intensity and photoprotection under intense sunshine to prevent the oxidative damage of reaction centers. Whereas it is widely accepted that such a…
