A levitating magnetometer detects weak magnetic signals from the brain

Researchers have developed a highly sensitive magnetometer that can detect the faint magnetic fields generated by electrical activity in the human brain. The device uses laser beams to monitor the movement of a microscopic magnet levitating in a vacuum chamber.

Unlike many existing magnetic-field sensors, the new technology does not require temperatures close to absolute zero or near-perfect shielding from external magnetic interference. This simpler approach could support future measurements of magnetic signals from the brain and heart. Similar magnetic levitation methods might also be used in the search for dark matter.

AI agents uncover errors in decades of scientific research

Artificial-intelligence agents trained to audit the scientific literature have identified errors dating back decades, including typographical mistakes and incorrect boiling-point values for molecules. AI systems can review scientific databases and research papers far more quickly than human fact-checkers, says computer scientist James Zou.

However, researchers caution that AI tools can also make mistakes. They argue that automated auditing should focus on objective problems, such as calculation errors and incorrect numerical values, rather than judging how researchers interpret data or assessing the originality of a study.

Rare FNIP1 mutations may protect against cardiometabolic disease

A rare mutation in the FNIP1 gene has been associated with several potential health benefits, including lower levels of abdominal fat and blood sugar. People carrying the mutation also appear to have a reduced risk of type 2 diabetes and heart disease.

The gene is involved in cellular metabolism and helps cells detect and respond to nutrients. Although these mutations are uncommon, the findings could point to new drug targets designed to reproduce some of their protective effects against cardiometabolic diseases.

Which scientific studies have the greatest influence on patents?

Patent citations — references included in legal documents filed to protect potentially profitable inventions — offer a way to track how academic research contributes to commercial innovation. A new analysis shows that some of the scientific studies most frequently cited in patents are not widely discussed in academic journals, and some authors are unaware of the reasons their work has attracted so many patent references.

The findings provide insight into the relationship between universities and industry. In particular, most of the research papers cited most often in patents were produced with public funding. (Nature | 15 min read) (Source: Nature analysis/relianceonscience.org)

Universities need stronger policies to prevent academic cheating

After suspecting that students had cheated on an at-home midterm examination, economist Robert Serrano held the final exam in person. The class average fell sharply. “The shock was not that cheating seems to have occurred on the take-home exam, but how prevalent it appeared to be,” he writes.

Serrano argues that universities should create dedicated committees to protect academic integrity and collaborate on best practices for using artificial intelligence in education. Clear policies are needed to ensure that AI tools support learning rather than undermine it.

How early-career scientists can build resilience

Geopolitical instability, rising living costs, research-funding cuts and declining public trust in science are making research careers feel increasingly uncertain for Generation Z, generally defined as people born after 1997.

Four early-career researchers tell Nature how scientists can stay motivated and develop resilience. Their advice includes finding a research environment that matches your needs, building a reliable support network and advocating for positive change within scientific institutions. “We, as scientists, must support each other and not give up on our careers,” says mycologist Jefferson Reis. “Staying in science is itself a form of resistance.”

Today we’re back in action after a short break — and Leif Penguinson is back with us, too.

In our last puzzle, Leif was gazing into Boca do Inferno, or “mouth of hell” in English, on the coast of Cascais, Portugal. Did you find the penguin? When you’re ready, here’s the answer.

I’ve read all of the emails you sent while we were away. Please send a fresh round of feedback to [email protected].
