The brains of people with Alzheimer’s disease contain lumps of so-called amyloid plaques which consist of misfolded protein aggregates. They cause nerve cell death in the brain and the first nerves to be attacked are the ones in the brain’s memory centre.
“When we treated brain tissue from mice suffering from Alzheimer’s disease with vitamin C, we could see that the toxic protein aggregates were dissolved. Our results show a previously unknown model for how vitamin C affects the amyloid plaques”, says Katrin Mani, reader in Molecular Medicine at Lund University.
“Another interesting finding is that the useful vitamin C does not need to come from fresh fruit. In our experiments, we show that the vitamin C can also be absorbed in larger quantities in the form of dehydroascorbic acid from juice that has been kept overnight in a refrigerator, for example”.
There is at present no treatment that cures Alzheimer’s disease, but the research is aimed at treatments and methods to delay and alleviate the progression of the disease by addressing the symptoms.
That antioxidants such as vitamin C have a protective effect against a number of diseases, from the common cold to heart attacks and dementia, has long been a current focus of research.“The notion that vitamin C can have a positive effect on Alzheimer’s disease is controversial, but our results open up new opportunities for research into Alzheimer’s and the possibilities offered by vitamin C”, says Katrin Mani.

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...
