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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
