[ad_1] Very small steps make a big difference to researchers who want to create large wafers of two-dimensional material. Atom-sized steps in a substrate provide the means for 2D crystals growing in a chemical vapor furnace to come together in perfect rank. Scientists have recently observed this phenomenon, and now a Rice University group has…
[ad_1] Rice University physicists Matthew Foster and Seth Davis want to view a vexing quantum puzzle from an entirely new perspective. They just need the right vantage point and a place colder than deep space. “There’s a process in strongly interacting physics where fundamental particles, like electrons, can come together and behave as if they…
[ad_1] A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has created a nanoscale “playground” on a chip that simulates the formation of exotic magnetic particles called monopoles. The study — published recently in Science Advances — could unlock the secrets to ever-smaller, more powerful memory devices, microelectronics, and…
[ad_1] For almost a decade, astronomers have tried to explain why so many pairs of planets outside our solar system have an odd configuration — their orbits seem to have been pushed apart by a powerful unknown mechanism. Yale researchers say they’ve found a possible answer, and it implies that the planets’ poles are majorly…
[ad_1] A recently discovered Weyl semimetal delivers the largest intrinsic conversion of light to electricity of any material, an international team lead by a group of Boston College researchers reports today in the journal Nature Materials. The discovery is based on a unique aspect of the material where electrons can be separated by their chirality,…
[ad_1] Resistance to antimalarial drugs is thought to result mainly from changes in the parasite’s genome. However, P. falciparum can also develop resistance to some antimalarial compounds by epigenetic changes, according to a new study led by ISGlobal, an institution supported by “la Caixa,” and the Institute of Tropical Medicine (ITM), Antwerp. This is of…
[ad_1] Researchers have proposed a new idea that may explain why some Antarctic icebergs are tinged emerald green rather than the normal blue, potentially solving a decades-long scientific mystery. Pure ice is blue because ice absorbs more red light than blue light. Most icebergs appear white or blue when floating in seawater, but since the…
[ad_1] Optical clocks of the National Institute of Information and Communications Technology (NICT, Japan) and LNE-SYRTE (Systemes de Reference Temps-Espace, Observatoire de Paris, Universite PSL, CNRS, Sorbonne Universite, France) evaluated the latest “one second” tick of the International Atomic Time (TAI) and provided these data to the Bureau International des Poids et Mesures (BIPM) to…
[ad_1] People exposed to trauma are less able to suppress unwanted emotional memories due to neural and behavioral disruptions in their brain that may contribute to the development of post-traumatic stress disorder (PTSD). PTSD is characterized by intense reliving of the trauma that is repetitive, intrusive and incapacitating. The intrusive nature of these hallmark symptoms…
[ad_1] Our brain comprises 85 billion nerve cells and just as many so-called glial cells, which work in close contact with the former to guarantee their proper function. All originate from brain stem cells. But what decides when and how many of them become neurons or glial cells? A new study led by the Laboratory…
