While the vision-impaired Hubble Space Telescope needed optical doctoring from shuttle astronauts, vision researchers back on Earth were wondering if the human eye was clever enough to fix itself.
Now a neurobiology study at Cornell University suggests that internal parts of the eye indeed can compensate for less-than-perfect conditions in other parts -- either developmentally (during the lifetime of one individual) or genetically (over many generations).
Results of the study, "Internal compensation for corneal astigmatism and high-order aberrations of the eye," were reported to the fourth International Congress of Wavefront Sensing and Aberration-free Refraction Correction, Feb. 14-16 in San Francisco, by Howard C. Howland, Jennifer E. Kelly and Toshifumi Mihashi. Howland is a Cornell professor of neurobiology and behavior and director of the university’s Developmental Vision Laboratory; Mihashi is the chief scientist at the research institute of the Tokyo-based Topcon Corp., manufacturer of a wavefront analyzer used in the study; and Kelly is a Cornell senior who used the wavefront analyzer as part of her honors thesis by testing the vision of 20 other undergraduate students.

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...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
