Study using new method of dating corals reveals that sea level is more variable over shorter periods of time than previously thought
Sea level may be far more variable over shorter periods of time than can be explained by natural variations in the Earths orbit. Scientists using a new method of dating fossil coral reefs have uncovered evidence that sea level is capable of changing by as much as 30 meters in just a few thousand years--more quickly and more dramatically than previously believed. The study, carried out by geochemists William Thompson and Steven Goldstein at the Lamont-Doherty Earth Observatory, a part of the Earth Institute at Columbia University, appears in the April 15 issue of the journal Science.
"People tend to associate substantial sea level changes like this with long-term changes in the Earths climate, like the onset of an ice age," says Thompson, lead author on the paper and currently a post-doctoral researcher at Woods Hole Oceanographic Institute. "But weve shown this isnt necessarily true." Thompson carried out the research as part of his doctoral research at Lamont.

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...
