Malaria parasites transform healthy red blood cells into rigid versions of themselves that clump together, hindering the transportation of oxygen. The infectious disease affects more than 200 million people across the world and causes nearly half a million deaths every year, according to the World Health Organization's 2018 report on malaria. Until now, however, researchers did not have a strong understanding of how the parasite so effectively infiltrated a system's red blood cells.
Scientists at Tokyo Institute of Technology(Tokyo Tech) explore a new material combination that sets the stage for magnetic random access memories, which rely on spin--an intrinsic property of electrons-- and could outperform current storage devices. Their breakthrough published in a new study describes a novel strategy to exploit spin-related phenomena in topological materials, which could spur several advances in the field of spin electronics. Moreover, this study provides additional insight into the underlying mechanism of spin-related phenomena.
Researchers led by Professor MATSUYAMA Hideto and Professor YOSHIOKA Tomohisa at Kobe University's Research Center for Membrane and Film Technology have succeeded in developing an ultrathin membrane with a fouling-resistant silica surface treatment for high performance separation of oil from water.
Furthermore, this membrane was shown to be versatile; it was able to separate water from a wide variety of different oily substances.
These results were published online in the Journal of Materials Chemistry A on October 3 2019.
Introduction
For many people, the New Year is a time to adopt new habits as a renewed commitment to personal health. Newly enthusiastic fitness buffs pack into gyms and grocery stores are filled with shoppers eager to try out new diets.
Imagine a world where people could only talk to their next-door neighbor, and messages must be passed house to house to reach far destinations.
Until now, this has been the situation for the bits of hardware that make up a silicon quantum computer, a type of quantum computer with the potential to be cheaper and more versatile than today's versions.
Researchers at LSTM have identified a completely new mechanism by which mosquitoes that carry malaria are becoming resistant to insecticide.
After studying both Anopheles gambiae and Anopheles coluzzii, two major malaria vectors in West Africa, they found that a particular family of binding proteins situated in the insect's legs were highly expressed in resistant populations.

Typhoon Phanfone, known locally in the Philippines as Ursula, was making landfall in the central part of the country when NASA-NOAA's Suomi NPP satellite passed overhead on Dec. 24.
Suomi NPP's VIIRS instrument provided a visible image of Phanfone that showed its center had made landfall in the eastern Visayas region of the Philippines. The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of 5 instruments aboard Suomi NPP. VIIRS and other satellite imagery has shown an intermittent eye feature peeking out within a compact area of sustained deep central convection.
A new study led by NIMS researchers reveals that, in solid electrolytes, a Si anode composed only of commercial Si nanoparticles prepared by spray deposition -- the method is a cost-effective, atmospheric technique -- exhibits excellent electrode performance, which has previously been observed only for film electrodes prepared by evaporation processes. This new result therefore suggests that a low-cost and large-scale production of high-capacity anodes for use in all-solid-state Li batteries is possible.
International Journal of Modern Physics has published an article by the IKBFU Physics and Mathematics Institute Artyom Astashenok and the Institute's MA student Alexander Teplyakov. The article refers to the issue of the "Dark Enegry" and an assumption is made that the Universe has borders.
Artyom Astashenok told:
Silicene consists of a single layer of silicon atoms. In contrast to the ultra-flat material graphene, which is made of carbon, silicene shows surface irregularities that influence its electronic properties. Now, physicists from the University of Basel have been able to precisely determine this corrugated structure. As they report in the journal PNAS, their method is also suitable for analyzing other two-dimensional materials.
A major issue with operating ring-shaped fusion facilities known as tokamaks is keeping the plasma that fuels fusion reactions free of impurities that could reduce the efficiency of the reactions. Now, scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found that sprinkling a type of powder into the plasma could aid in harnessing the ultra-hot gas within a tokamak facility to produce heat to create electricity without producing greenhouse gases or long-term radioactive waste.
Dust plays a crucial role in the life and health of our planet. In our modern world, dust-borne nutrients traveling in great dust storms from the Saharan Desert fertilize the soil in the Amazon Rainforest and feed photosynthetic organisms like algae in the Atlantic Ocean. In turn, it is those organisms that breathe in carbon dioxide and expel oxygen.
Scientists at St. Jude Children's Research Hospital have discovered a new way that the molecule RIPK1 leads to cell death in infected, damaged or unwanted cells showing that more than one mechanism can trigger the process. The findings appeared online today in the Journal of Experimental Medicine.
"Our findings break the existing dogma that RIPK1 kinase activity is required for cell death," said Thirumala-Devi Kanneganti, Ph.D., a member in the St. Jude Department of Immunology.
When you search your lost keys with a flash lamp, when bats detect obstacles during their night flight, or when car radars locate other cars on the road, the very same physical principle works. Be it light, sound, or an electromagnetic wave in general, a probe beam is sent ahead, and a reflected wave of the same kind carries the relevant information back to the detector. That also explains why stealth aircrafts can escape radars: by absorbing radar energy, no signal is reflected back, and they become invisible.
