Artificial intelligence can now predict long-term risks of heart attack and cardiac death

19.12.2019 Health Problems

A new study in Cardiovascular Research finds that machine learning, the patterns and inferences computers use to learn to perform tasks, can predict the long-term risk of heart attack and cardiac death. Indeed, machine learning appears to be better at predicting heart attacks and cardiac deaths than the standard clinical risk assessment used by cardiologists. Researchers here studied subjects from […]

Converging solutions: Artificial networks shed light on human face recognition

30.10.2019 Health Problems

Our brains are so primed to recognize faces—or to tell people apart—that we rarely even stop to think about it, but what happens in the brain when it engages in such recognition is still far from understood. In a new study reported today in Nature Communications, researchers at the Weizmann Institute of Science have shed new light on this issue. […]

Why screen time can disrupt sleep—scientists uncover how certain retinal cells respond to artificial illumination

28.11.2018 Health Problems

For most, the time spent staring at screens—on computers, phones, iPads—constitutes many hours and can often disrupt sleep. Now, Salk Institute researchers have pinpointed how certain cells in the eye process ambient light and reset our internal clocks, the daily cycles of physiological processes known as the circadian rhythm. When these cells are exposed to artificial light late into the […]

Artificial intelligence can determine lung cancer type

18.09.2018 Health Problems

A new computer program can analyze images of patients’ lung tumors, specify cancer types, and even identify altered genes driving abnormal cell growth, a new study shows. Led by researchers at NYU School of Medicine and published online in Nature Medicine, the study found that a type of artificial intelligence (AI), or “machine learning” program, could distinguish with 97 percent […]

Artificial placenta created in the laboratory

14.08.2018 Health Problems

In order to better understand important biological membranes, it is necessary to explore new methods. Researchers at Vienna University of Technology (Vienna) have succeeded in creating an artificial placental barrier on a chip, using a high-resolution 3-D printing process. The placenta has an essential and highly complex task: it must ensure the exchange of important substances between the mother and […]

An artificial mole as an early warning system

18.04.2018 Health Problems

Alongside cardiovascular disease, cancer has become the top cause of death in industrialised countries. Many of those affected are diagnosed only after the tumour has developed extensively. This often reduces the chance of recovery significantly: the cure rate for prostate cancer is 32 percent and only 11 percent for colon cancer. The ability to detect such tumours reliably and early […]
