Medical malpractice cases frequently try to link injuries to the white matter of a newborns brain -- a precursor to cerebral palsy and other disorders -- to the babys delivery, though a new Johns Hopkins study demonstrates that such injuries are more closely associated with neonatal infections.
White matter, the tracts of nerve fibers that communicate messages in the brain, is generally injured at so-called "end zones" between the long, penetrating arteries that supply blood to the brain. These zones are susceptible to the type of fall in cerebral blood flow and oxygen that could occur during complications in delivery, as marked by excess acid in the umbilical cord.
The Hopkins team reviewed medical records of 150 premature babies who had white matter injuries and were born between May 1994 and September 2001. They compared each babys delivery to that of the next healthy baby delivered at the same gestational age (23-24 weeks), looking for causes of problems.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
