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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
