Northwestern University researchers have identified a key molecular "signal" that allows malarial parasites to release virulence proteins inside human red blood cells.
The investigators, led by Kasturi Haldar and N. Luisa Hiller, also found that the process by which the malarial parasite remodels red blood cells is far more complex than scientists previously had realized. Haldar is Charles E. and Emma H. Morrison Professor in Pathology and professor of microbiology-immunology and Hiller a sixth-year student in the Integrated Graduate Program in the Life Sciences at Northwestern University Feinberg School of Medicine. Other key researchers on this study were Souvik Bhattacharjee; Christiaan van Ooij; Konstantinos Liolios; Travis Harrison; and Carlos Estrano.
Findings from the Northwestern study were published in the Dec. 10 issue of the journal Science. Malaria is a blood-borne illness transmitted by mosquitoes. Forty percent of the world’s population lives at risk for infection, and between 200 and 300 million people are afflicted each year, particularly in underdeveloped and impoverished tropical and sub-Saharan countries. Plasmodium faciparum is the most virulent form of the four human malarial parasite species, killing over 1 million children each year, and is responsible for 25 percent of infant mortality in Africa, according to the World Health Organization.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
