We all know that cancer happens more often in older people. The reason seems to be that cancer develops slowly, first passing through a series of benign stages. Our understanding of how cancer develops over a lifetime is limited by the extreme difficulty of monitoring these slow changes, but new work reported this week aids this effort by employing mathematical modelling to analyze epidemiological data on the relationship between age and cancer and generating ideas about how cancer progresses over time.
The findings come from Steven Frank at the University of California in Irvine, who analyzed how the rates of breast, prostate, colon, and lung cancers rise with age. Older people do indeed get these cancers much more often, but the increase with age slows down later in life.
In the new work, Frank asks how the passage through the benign early stages of cancer would cause the increase in cancer incidence to slow as one ages. His theory is that, early in life, we are well-protected because all of our cells have many stages to go through before they may become cancerous. As we get older, some of our cells progress through the early stages. By midlife, much of the waiting for the slow passage of the early stages is over. A few of our cells are poised on the brink of cancer, with only a few steps to go.

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...
