New research suggests that carbon, oxygen, and hydrogen cosmic rays travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently. The international research team analyzed data from the CALET instrument on the International Space Station to arrive at the results, which help address the age-old question: How is matter generated and distributed across the universe?
Just as the skeleton and muscles move the human body and hold its shape, the cells of the body are stabilised and moved by a cellular skeleton. This cellular skeleton is a dynamic structure, constantly changing and renewing. It consists of different types of protein filaments, which include intermediate filaments and microtubules. Researchers from Göttingen University are the first to succeed in observing a direct interaction between microtubules and intermediate filaments outside the cell, and in measuring this.
An international team led by Princeton researchers explored quantum structures called kagome lattices and found insights into the fundamental understanding of quantum order leading to orbital magnetism - that is, magnetism that arises from extended orbital motion of electrons rather than their spin. The findings hint at behaviors that could be precursors of unconventional superconductivity and an anomalous Hall effect.
It could be a milestone on the path to detecting life on other planets: Scientists under the leadership of the University of Bern and of the National Centre of Competence in Research (NCCR) PlanetS detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground. The measurement technology could also open up opportunities for remote sensing of the Earth.
Two recent studies led by researchers from the University of Minnesota Medical School add new evidence to the impact of how drug price increases affect US patients and the overall cost of health care.
Professor Konstantin Arutyunov of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE), together with Chinese researchers, has developed a graphene-based mechanical resonator, in which coherent emission of sound energy quanta, or phonons, has been induced. Such devices, called phonon lasers, have wide potential for application in information processing, as well as classical and quantum sensing of materials. The study is published in the journal Optics Express.
Scientists have developed a new technique that could revolutionize medical imaging procedures using light.
The Korea Institute of Science and Technology (KIST) had developed a novel, high-performance, economical anode material for use in sodium-ion secondary batteries, which are more cost-effective than lithium-ion batteries. This novel material can store 1.5 times more electricity than the graphite anode used in commercial lithium-ion batteries and its performance does not degrade even after 200 cycles at very fast charging/discharging rates of 10 A/g.
Massive heavy-lift crane vessels, capable of hauling thousands of tons, navigate the rough waves and strong winds offshore to construct wind turbines and oil fields in the ocean. An international team of researchers has developed a new modeling system to help improve the control, and ultimately the safety, of such vessels.
Properties of materials are often defined by imperfections in their atomic structure, especially when the material itself is just one atom thick, such as graphene. Researchers at the University of Vienna have now developed a method for controlled creation of such imperfections into graphene at length scales approaching the macroscopic world. These results, confirmed by atomically resolved microscope images and published in the journal Nano Letters, serve as an essential starting point both for tailoring graphene for applications and for the development of new materials.
