Researchers from Mosquito Alert (who belong to CEAB-CSIC, CREAF and UPF) together with researchers from the University of Budapest have shown that an artificial intelligence algorithm is capable of recognizing the tiger mosquito (Aedes albopictus) in the photos sent by Mosquito Alert users.
Organizing functional objects in a complex, sophisticated architecture at the nanoscale can yield hybrid materials that tremendously outperform their solo objects, offering exciting routes towards a spectrum of applications. The development in synthetic chemistry over past decades has enabled a library of hybrid nanostructures, such as core-shell, patchy, dimer, and hierarchical/branched ones.
Nevertheless, the material combinations of these non-van der Waals solids are largely limited by the rule of lattice-matched epitaxy.
Twenty-seven years ago, more than 1 million Rwandans were killed during the genocide against the Tutsi in Rwanda from April 7 to July 4, 1994. It is estimated that 100,000 to 250,000 women were raped during the 100-day genocide, and that 10,000 children were born as a result.
A research group has developed an ion-selective smart porous membrane that can respond to outer stimuli, potentially paving the way for new applications in molecular separation and sensing applications.
Porous thin films have attracted the attention of scientists because of their potential use in sensors, energy harvesting, and ion/molecular separation.
Nanostructure properties, such as pore size, thickness, and film density, affect molecular selectivity and molecular permeability. Surface properties also have a significant impact on molecular selectivity.
The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests.
The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.
Researchers from Tokyo Medical and Dental University (TMDU), collaborating with scientists from the Marine Biological Laboratory (MBL) and RIKEN, develop a novel technique for live-cell fluorescent imaging which leads them to discover a new actin structure in starfish early embryos.
Millions of people suffer from psoriasis, a chronic, autoimmune disorder that causes scaly patches on the skin and often precedes psoriatic arthritis. While no cure exists, treatments range from topical creams to injected medications that block inflammation. To improve treatment options, scientists need to better understand the dysregulation of the immune system that leads to these lesions.
WASHINGTON -- In a new study, researchers have shown that 3D printing can be used to make highly precise and complex miniature lenses with sizes of just a few microns. The microlenses can be used to correct color distortion during imaging, enabling small and lightweight cameras that can be designed for a variety of applications.
Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these enormous stars has a major impact on our understanding of their evolution prior to their explosion. It also represents the largest uncertainty for scientists studying their structure and evolution.
Irvine, CA - May 13, 2021 - A new University of California, Irvine-led study finds low serum levels of the sugar N-acetylglucosamine (GlcNAc), is associated with progressive disability and neurodegeneration in multiple sclerosis (MS).
The study, done in collaboration with researchers from Charité - Universitätsmedizin Berlin, Germany, and the University of Toronto, Canada, is titled, "Association of a Marker of N-Acetylglucosamine With Progressive Multiple Sclerosis and Neurodegeneration," The study was published this week in JAMA Neurology.
According to data from a cohort of adult and pediatric patients with antibody deficiencies, patients that often fail to make protective immune responses to infections and vaccinations showed robust T-cell activity and humoral immunity against SARS-CoV-2 structural proteins. The new study, led by researchers at Children's National Hospital, is the first to demonstrate a robust T-cell response against SARS-CoV-2 in immunocompromised patients.
Scientists at the Skolkovo Institute of Science and Technology (Skoltech) and their colleagues from the University of Graz & the Kanzelhöhe Observatory (Austria) and the ESA European Space Operations Centre developed a method and software called RESONANCE to predict the solar radio flux activity for 1-24 months ahead. RESONANCE will serve to improve the specification of satellite orbits, re-entry services, modeling of space debris evolution, and collision avoidance maneuvers. The research results were published in the high-profile Astrophysical Journal Supplement Series.
The work was sponsored by Russian Science Foundation; the project, headed by Professor Anatolii Mokshin, is titled "Theoretical, simulating and experimental research of physico-mechanical traits of amorphous-producing systems with heterogeneous local visco-elastic properties".
PROVIDENCE, R.I. [Brown University] -- Since the 1950s, political scientists have theorized that political polarization -- increased numbers of "political partisans" who view the world with an ideological bias -- is associated with an inability to tolerate uncertainty and a need to hold predictable beliefs about the world.
But little is known about the biological mechanisms through which such biased perceptions arise.
The primary cilium, an antenna-like subcellular structure ('organelle') protruding from the outside of many types of vertebrate cells, has an important but previously overlooked role in guiding the growth of lymphatic vessels, shows a new study. The authors show for the first time that mouse and human lymphatic endothelial cells (LECs) - which make up the inner and outer lining of lymphatic vessels - use primary cilia.
