Publication of the Chemistry Laboratory in the journal PNAS on March 7, 2023. Communication of the CNRS-INC on March 28, 2023. Electroporation consists of perforating the cell membrane with an electric field to pass a therapeutic substance through it. A team from the Chemistry Laboratory (CNRS/ENS de Lyon/Claude Bernard Lyon 1 University) and their colleagues from the University of Freiburg im Breisgau have published in the journal PNAS some essential elements for understanding this widely used but still little understood phenomenon.

To study valuable manuscripts and other written artefacts around the world, the Understanding Written Artefacts cluster of excellence at Universität Hamburg has developed a mobile laboratory. The first mobile unit has now been delivered. In the fall, it will be sent to India so that researchers there can study palm-leaf manuscripts that belong to the world's document heritage.

German-Japanese research team from Universities of Freiburg and Nagoya identifies what determines the site of cell division in plants For a new plant to grow from a seed, cells need to divide numerous times. Daughter cells can each take on different tasks and sometimes vary in size. How plants determine the plane of cell division in this process, known as mitosis, is being researched by Ralf Reski and Dr. Elena Kozgunova from the University of Freiburg in a joint effort with Prof. Dr. Gohta Goshima from Nagoya University.

The human brain has 100 billion neurons, making 100 trillion connections. Understanding the precise circuits of brain cells that orchestrate all of our day-to-day behaviors-such as moving our limbs, responding to fear and other emotions, and so on-is an incredibly complex puzzle for neuroscientists.

Like a work of art enshrined in a museum, some stones end up on a pedestal of ice in nature, with no human intervention. This "Zen stone" phenomenon, named after the stacked stones in Japanese gardens, appears on the surface of frozen lakes, Lake Baikal (Russia) in particular. These structures result from the phenomenon of sublimation, which causes a body, in this case ice, to change from solid to gaseous form without the intermediary form of a liquid.

Berkeley Lab researchers are part of an international team that reports a high-sensitivity measurement by underground CUPID-Mo experiment Nuclear physicists affiliated with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) played a leading role in analyzing data for a demonstration experiment that has achieved record precision for a specialized detector material.
