Inspired by the tetromino shapes in the classic video game Tetris, researchers in the US have designed a simple radiation detector that can monitor radioactive sources both safely and efficiently. Created by Mingda Li and colleagues at the Massachusetts Institute of Technology, the device employs a machine learning algorithm to process data, allowing it to build up accurate maps of sources using just four detector pixels.

Wherever there is a risk of radioactive materials leaking into the environment, it is critical for site managers to map out radiation sources as accurately as possible.

The Church of Jesus Christ of Latter-day Saints published some statements about artificial intelligence (AI). The Church is by far the largest Mormon denomination – and that of which I’m a member. Its statements influence the perspectives and actions of millions of Mormons worldwide. Friends called the Church’s statements to my attention, asking for my thoughts.

Is there intelligent life somewhere in the cosmos? People have been debating this issue for centuries, if not millennia. However, with programs like SETI (Search for Extraterrestrial Intelligence) employing radio telescopes to actively listen for radio messages from alien civilizations, we’ve only recently had a real chance of finding out.

Should these searches be successful, what should we anticipate finding? I made this assumption during a talk at a conference for the SETI project Breakthrough Listen: it is highly unlikely to be little green men.

As the AI bubble continues inflating at lightning speed, the people doing the industry’s grunt work are feeling the churn.

In interviews with CNBC, AI engineers from giant companies including Amazon, Google, and Microsoft say that they’ve been under immense pressure to build new products for their employers — except that on many occasions, the features they work tirelessly to deliver are shelved at the finish line.

One Amazon AI engineer, who spoke to CNBC anonymously over concerns of retaliation, said that he was assigned an urgent project on a Friday night that was due Monday morning by 6 am. Despite having out-of-town company, he blew them off to spend the entire weekend working on the project — only to learn later that it had been “deprioritized.”

A study from the Hackett group at EMBL Rome led to the development of a powerful epigenetic editing technology, which unlocks the ability to precisely program chromatin modifications.

Understanding how genes are regulated at the molecular level is a central challenge in modern biology. This complex mechanism is mainly driven by the interaction between proteins called transcription factors, DNA regulatory regions, and epigenetic modifications – chemical alterations that change chromatin structure. The set of epigenetic modifications of a cell’s genome is referred to as the epigenome.
