Although laptops and tablets have flooded into schools over the past decade, a new study published online on March 1, 2024, in ECNU Review of Education warns that the real “digital divide” has not disappeared but has become more hidden. The study points out that in the “post-digital era,” digital inequality has shifted from a lack of hardware to how technology is used, and school leaders play a critical role in this.

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and medicine. Despite this, their ultrashort duration has made them elusive and difficult to measure.  About ten years ago, researchers from Lund University and Porto University introduced a tool for measuring pulse duration of ultrafast lasers. The same team has now achieved a breakthrough that enables the measurement of individual laser pulses across a wider parameter range in a more compact setup.

Researchers have developed the first scientifically validated ‘personality test’ framework for popular AI chatbots, and have shown that chatbots not only mimic human personality traits, but their ‘personality’ can be reliably tested and precisely shaped – raising implications for AI safety and ethics.
