Soviet cosmonaut Yuri Gagarin became the first man in space 60 years ago next week.

What are the best ways to search for technosignatures?

The search for extraterrestrial intelligence (SETI) has long roots in human history. With the advent of modern technologies, scientists were finally able to start scanning the skies for any sign of life. When the search first started back in the 1960s, it focused almost exclusively on trying to detect radio signals. Over the decades, no irrefutable evidence of any artificial radio signals was ever found. Financial support started to drift away from the discipline, and where the money goes so do many scientists.

Hubble takes a spiral snapshot

The luminous heart of the galaxy M61 dominates this image, framed by its winding spiral arms threaded with dark tendrils of dust. As well as the usual bright bands of stars, the spiral arms of M61 are studded with ruby-red patches of light. Tell-tale signs of recent star formation, these glowing regions lead to M61's classification as a starburst galaxy.

Technology news

A single spin-orbit torque device to sense 3D magnetic fields

Sensors that can detect magnetic fields have many potential applications, for instance, in the development of sophisticated medical devices and transportation systems. Most approaches for detecting 3D magnetic fields developed so far, however, require several sensors, which makes them bulky and difficult to implement on a large-scale.

X-ray study recasts role of battery material from cathode to catalyst

An international team working at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices.

Robo-starfish aims to enable closer study of aquatic life

Biologists have long experienced the challenges of documenting ocean life, with many species of fish proving quite sensitive to the underwater movements of humans.

The coronavirus pandemic has forced parents' hands on data collection and privacy issues

With the return to remote learning during the third wave of the COVID-19 pandemic, parents and students are agreeing to risky data collection practices and privacy-invasive technologies. This unprecedented collection of data includes video recordings of student's interactions with their teachers, collection of health information such as whether an absence is related to COVID-19 symptoms, system log-in time and student chat history.

In an AI world we need to teach students how to work with robot writers

Robots are writing more of what we read on the internet. And artificial intelligence (AI) writing tools are becoming freely available for anyone, including students, to use.

Researchers investigate a new form of interaction between humans and machines

Sifting through job applications, analyzing X-ray images, suggesting a new track list—interaction between humans and machines has become an integral part of modern life. The basis for these artificial intelligence (AI) processes is algorithmic decision-making. However, as these are generally difficult to understand, they often prove less useful than anticipated. Researchers at Paderborn and Bielefeld University are hoping to change this, and are discussing how the explainability of artificial intelligence can be improved and adapted to the needs of human users. Their work has recently been published in the respected journal IEEE Transactions on Cognitive and Developmental Systems. The researchers describe explanation as a social practice, in which both parties co-construct the process of understanding.
