At the end of the 1980s, 90,000 Swedish women were sent a questionnaire on their dietary habits in connection with their mammography scan. Now, with the help of another questionnaire a decade later and the cancer registry, scientists at Karolinska Institutet have concluded that women who eat fatty fish gain significant protection against renal cancer.
At least one portion of fatty fish a week during the period (1987-2004) reduced the risk of renal cancer by 74 per cent compared with those who never ate fatty fish. The group who ate fresh fish at least once a week but for whom follow-up information were unavailable, saw a 40 per cent reduction.
“This is the first time that a link between the consumption of fatty fish and renal cancer has been studied,” says Professor Alicja Wolk, one of the scientists working with the study. “The reason previous studies have been unable to demonstrate a link between fish consumption and renal cancer is that they made no distinction between fatty and non-fatty fish.”
One significant difference between oily and non-fatty fish lies in how much omega-3 fatty acids and vitamin D they contain – substances that, according to earlier cell studies, seem to protect against cancer. Fatty fish contains more omega-3 fatty acids than non-oily fish, and 3 to 5 times as much vitamin D. As fatty fish, the study included salmon, raw herring, sardines and mackerel; as non-fatty, cod and tuna (amongst other kinds).
The study is to be published in the Journal of the American Medical Association (JAMA) on 20 September.

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...
