Could a simple blood test reveal how well someone is aging? A team of researchers led by Wolfram Weckwerth from the University of Vienna, Austria, and Nankai University, China, has combined advanced metabolomics with cutting-edge machine learning and a novel network modeling tool to uncover the key molecular processes underlying active aging.

Their study, published in npj Systems Biology and Applications, identifies aspartate as a dominant biomarker of physical fitness and maps the dynamic interactions that support healthier aging.

It has long been known that exercise protects mobility and lowers the risk of chronic disease...

An article published in the journal Communications Medicine points to a correlation between disturbances in Earth’s magnetic field resulting from solar storms and an increase in the frequency of heart attacks, especially among women.

The authors reached this conclusion by analyzing data from the public health network of São José dos Campos, in the state of São Paulo, Brazil, recorded between 1998 and 2005, a period considered to be one of intense solar activity.

Focusing on hospital admissions for myocardial infarction, the analysis included information from 871 men and 469 wom...

A new Cochrane review demonstrates that vaccines for respiratory syncytial virus (RSV) are both safe and effective in protecting vulnerable groups that are most at risk of serious illness, including older adults and infants.

RSV is a common virus that causes coughs and colds but can also lead to life-threatening lung infections like pneumonia. Children under the age of two are at the highest risk of severe RSV infection and death, with older adults also vulnerable.

An international group of researchers analyzed 14 clinical trials with over 100,000 participants, including older adults, pregnant women, women of childbearing age, and children...

Harvard physicists working to develop game-changing tech demonstrate 3,000 quantum-bit system capable of continuous operation

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits could simultaneously store more information than the number of particles in the known universe.

Now process this: Harvard scientists just unveiled a system that was 10 times bigger and the first quantum machine able to operate continuously without restarting.

In a paper published in the journal Nature, the team demonstrated a system of more than 3,000 quantum bits (or qubits) that could run for more than two hours, surmounting a series of technical challenges and representing a significant step toward building the super computers, wh...
