A diet rich in plant-based products reduces the risk of cognitive impairment in the elderlyA diet rich in plant products reduces the risk of cognitive impairment and dementia in the elderly. This is the result of a study by the Biomarkers and Nutritional Food Metabolomics Research Group of the Faculty of Pharmacy and Food Sciences of the University of Barcelona (UB) and the CIBER on Frailty and Healthy Aging (CIBERFES). The paper, published in the journal Molecular Nutrition and Food Research, is led by Cristina Andrés-Lacueva, professor at the Faculty of Pharmacy and Food Sciences and head of the Biomarkers and Nutritional Metabolomics of Food Research Group of the UB and the Biomedical Research Network Center in Frailty and Healthy Aging (CIBERFES), which is also part of the Food Innovat...

A new super-cooled microwave source boosts the scale-up of quantum computersResearchers in Finland have developed a circuit that produces the high-quality microwave signals required to control quantum computers while operating at temperatures near absolute zero. This is a key step towards moving the control system closer to the quantum processor, which may make it possible to greatly increase the number of qubits in the processor. One of the factors limiting the size of quantum computers is the mechanism used to control the qubits in quantum processors. This is normally accomplished using a series of microwave pulses, and because quantum processors operate at temperatures near absolute zero, the control pulses are normally brought into the cooled environment via broadband cables from room ...

DeepMind AI helps study strange electrons in chemical reactions Strange so-called fractional electrons are crucial to many chemical reactions, but traditional methods cannot model them – a problem that DeepMind has used machine learning to fix Physics ...
