Group of compounds found in red wine, vegetables simulate benefit of low-calorie diet
Mice, rats, worms, flies, and yeast all live longer on a low-calorie diet, which also seems to protect mammals against cancer and other aging-related diseases. Now, in yeast cells, researchers at Harvard Medical School and BIOMOL Research Laboratories have for the first time found a way to duplicate the benefits of restricted calories in yeast with a group of compounds found in red wine and vegetables. One compound extended yeast life span by up to 80 percent. The molecules are also active in human cells cultured in the laboratory.
The findings are reported in the August 24 Nature advanced online edition. The research suggests a promising route to find and develop drugs to lengthen life and prevent or treat aging-related diseases.

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...
