Treating arthritis with algae

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis. This is based on a polysaccharide, a long-chain sugar molecule, originating from brown algae. When chemically modified, this "alginate" reduces oxidative stress, has an anti-inflammatory effect in cell culture tests and suppresses the immune reaction against cartilage cells, thereby combating the causes of arthritis. The research is, however, still in its infancy.Arthritis is the most-widespread joint disease, with around 90 percent of all people over 65 being affected to varying degrees, but this degenerative disease...Powered by WPeMatico

Witnessing turbulent motion in the atmosphere of a distant star

For the first time, astronomers have succeeded in obtaining a map of the turbulent motions in the atmosphere of a star other than the Sun, thanks to an innovative technique that combines three telescopes at the European Southern Observatory (ESO) on Cerro Paranal located in northern Chile. The astronomer Keiichi Ohnaka at the Universidad Católica del Norte in Antofagasta, Chile, led the research. He and his partners Gerd Weigelt and Karl-Heinz Hofmann from the Max Planck Institute for Radio Astronomy in Bonn, Germany obtained unprecedented velocity-resolved images of the surface and the atmosphere of a distant star.The team was able to measure the intensity (Figure 1) and velocity of the gas at each position over the surface and atmosphere of the red supergiant star...Powered by WPeMatico...

Machine control to user: Mitsubishi Electric and Fraunhofer IPT to unveil smart system for mobile devices in manufacturing

Nowadays, workers on the shop floor are required to operate increasingly complex machinery whilst reacting flexibly to any disturbances. At the EMO Metal Working Trade Fair in Hanover from 18 – 23 September in Hall 25, Booth B94, Mitsubishi Electric and the Fraunhofer Institute for Production Technology IPT will be revealing for the first time, a smart information system which will deliver information tailored to match the requirements of the job in hand, straight from the machine control unit to the machine operator. This will slash the time required by the operator to make a decision and will permit even unfamiliar tasks to be solved more swiftly and more flexibly.Costs rapidly start to mount up in production when a machine unexpectedly comes to a standstill. The onus is then on the mach

Self-powered paper-based ‘SPEDs’ may lead to new medical-diagnostic tools

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses - powered only by the user's touch - and reads out the color-coded test results, making it easy for non-experts to understand."You could consider this a portable laboratory that is just completely made out of paper, is inexpensive and can be disposed of through incineration," said...Powered by WPeMatico

Such detailed images of the pathogen that causes sleeping sickness inside a host are unique so far: They illustrate the manifold ways in which the parasites move inside a tsetse fly. A research team from the University of Würzburg's Biocenter has presented the images.Single specimens of the vermicular pathogens causing sleeping sickness swim inside the gut of the tsetse fly between blood cells which the fly has ingested...Powered by WPeMatico

New Test for Rare Immunodeficiency

Researchers at the University of Basel have developed a test to quickly and reliably diagnose a rare and severe immune defect, hepatic veno-occlusive disease with immunodeficiency. They reported on their findings in the Journal of Clinical Immunology.Rare diseases are often only diagnosed very late, especially since in many cases, diagnostic tests are not available or are only available in a few...Powered by WPeMatico

Meter-sized single-crystal graphene growth becomes possible

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
"Preparation determines the future". Since the discovery of graphene, the synthesis of graphene has long been a hot spot in graphene community. Using transition metals such as Cu or Ni as substrate, scientists have realized the preparation of large-area graphene films.Especially, high-quality large-scale continuous monolayer graphene has been successfully grown on Cu foils. This simple and low-cost method has been widely...Powered by WPeMatico
