How one medical group uses AI, machine learning to improve value-based care

While many hospitals and medical groups are exploring artificial and machine learning, Hill Physicians Medical Group in San Ramon, California, has already reaped noteworthy results using the technologies to advance value-based care work. “The efficiencies we’ve gained have allowed us to increase the number of charts collected by more than 200 percent,” said Jennifer Pereur, […]

Ytterbium: The quantum memory of tomorrow

Quantum communication and cryptography are the future of high-security communication. But many challenges lie ahead before a worldwide quantum network can be set up, including propagating the quantum signal over long distances. One of the major challenges is to create memories with the capacity to store quantum information carried by light. Researchers at the University […]

Surprising similarity between stripy black holes and high-temperature superconductors

Scientists don’t understand how some materials become superconducting at relatively high temperatures. Leiden physicists have now found a surprising connection with auxiliary black holes. It enables researchers to apply knowledge of black holes to the mystery of high-temperature superconductivity. The new study is published in Nature Physics. Superconductivity, discovered in Leiden in 1911, is exploited […]

Wearable device measures cortisol in sweat

The hormone cortisol rises and falls naturally throughout the day and can spike in response to stress, but current methods for measuring cortisol levels require waiting several days for results from a lab. By the time a person learns the results of a cortisol test—which may inform treatment for certain medical conditions—it is likely different […]
