A framework for building tighter security into 5G wireless communications has been created by a Ph.D. student working with the University of Portsmouth’s Artificial Intelligence and Data Center.

With its greater network capacity and ability to rapidly transmit huge amounts of information from one device to another, 5G is a critical component of intelligent systems and services—including those for health care and financial services.

However, the dynamic nature of 5G networks, the high volumes of data shared and the ever changing types of information transmitted means that these networks are extremely vulnerable to cyber threats and increasing risks of attack.

In recent years, NASA’s Parker Solar Probe has given us a close-up look at the sun. Among the probe’s revelations was the presence of numerous kinks, or “switchbacks,” in magnetic field lines in the sun’s outer atmosphere. These switchbacks are thought to form when solar magnetic field lines that point in opposite directions break and then snap together, or “reconnect,” in a new arrangement, leaving telltale zigzag kinks in the reconfigured lines.

Abdominal pain is a hallmark of many digestive disorders, including inflammatory bowel disease and irritable bowel syndrome. In an effort to develop targeted treatments for gut pain, scientists have discovered a new enzyme in gut bacteria and are using nanoparticles to deliver drugs inside cells.

Currently, there are no treatments specifically for gut pain, and existing painkillers are often insufficient at managing symptoms. These drugs—including opioids, NSAIDs, and steroids—also come with side effects, some of which directly harm the digestive system.

Scientists have achieved a breakthrough in analog computing, developing a programmable electronic circuit that harnesses the properties of high-frequency electromagnetic waves to perform complex parallel processing at light-speed.

The discovery points to a new era of computing that operates far beyond the limits of conventional digital electronics, using less energy, while performing massive calculations.

The study, “Programmable circuits for analog matrix computations,” has been published in Nature Communications.

The research was led by Dr...
