A research team from the Chinese Academy of Sciences elucidated the high-resolution structure of the Orf2971-FtsHi complex, a chloroplast motor complex from Chlamydomonas reinhardtii. The study reveals the highly complex protein composition and assembly details of the complex, and explores the potential translocation pathway of precursor proteins.

The study, conducted by Prof. Li Mei’s team from the Institute of Biophysics of the Chinese Academy of Sciences, and Prof. Yang Wenqiang’s team from the Institute of Botany is published in Molecular Plant.

The Orf2971-FtsHi complex is a structure with 20 subunits formed by 19 proteins, spanning the chloroplast inner membrane and extending into the intermembrane space as well as the stromal side.

A robot trained via video observation performs surgery with skill rivaling human doctors, moving robotic surgery closer to autonomous procedures.

Coelacanths are strange fish that are currently only known from two species found along the East African coast and in Indonesia. A team from the Natural History Museum (MHNG) and the University of Geneva (UNIGE) has succeeded in identifying an additional species, with a level of detail never before achieved. This discovery was made possible by the use of the European Synchrotron Radiation Facility (ESRF) in Grenoble, a particle accelerator for analyzing matter.

Teams lifted NASA’s Orion spacecraft for the Artemis II test flight out of the Final Assembly and System Testing cell and moved it to the altitude chamber to complete further testing on Nov. 6 inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida.

Engineers returned the spacecraft to the altitude chamber, which simulates deep space vacuum conditions, to complete the remaining test requirements and provide additional data to augment data gained during testing earlier this summer.

The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back.

The interface superconductor underwent a transition under a magnetic field and became more robust, the scientists said in the paper This suggests it has transformed into a “triplet superconductor.” — a type of superconductor that is more resistant to magnetic fields than conventional superconductors.

They conducted the research in conjunction with the National Institute of Standards and Technology. In earlier work, they demonstrated that thin films of gold and niobium naturally suppress decoherence — the loss of quantum properties due to external environmental interference.

Given its robust quantum qualities and its ability to suppress decoherence, this new superconducting material promises to be ideal for use in quantum computers, the scientists said. Minimizing decoherence within the system is a key challenge, which necessitates extreme measures to isolate the quantum computer from external influences, such as shifts in temperature or electromagnetic interference, as well as the use of error-correcting algorithms to ensure calculations remain accurate.

Surprising findings on bacterial aging have emerged from a study carried out by a team of researchers led by the biologist Dr. Ulrich Steiner at Freie Universität Berlin. In a new paper published in Science Advances, the team demonstrated that even genetically identical bacterial cells living in the same environment react differently to the aging process and that changes occur at different rates within different regions of the cell.
